Description
CLOGGING-PROOF AND JAMMING-PROOF CONSTANT TEMPERATURE VALVE
CORE
The invention relates to the technical field of thermostatic valve core, in particular to a clogging-proof and jamming-proof thermostatic valve core.
A prior art thermostatic valve now available in the market is shown in FIG. 1, comprising an upper casing 10, a lower casing 20, a spline rod 30, a guiding assembly 40, a plunger 50, paraffin wax temperature sensing component 60, and a working spring 70; the lower casing 20 partially sleeves the upper casing 10; the plunger 50 is slidably disposed in the lower casing 20 to move up and down inside the lower casing, and the plunger 50 is positioned on the paraffin wax temperature sensing component 60. When the paraffin wax temperature sensing component expands due to increase in temperature, the plunger 50 will be driven to move upwardly. The guiding assembly 40 is nested in the upper casing10; by rotating the spline rod 30, the guiding assembly 40 will be driven to move downwardly so as to drive also the paraffin wax temperature sensing component 60 and the plunger 50 to move downwardly.
Cold water enters to a top side of the plunger 50 from a cold water pipe opening 201 of the lower casing 20, and hot water enters a bottom side of the plunger 50 from a hot water pipe opening 202 of the lower casing 20; cold water flows through a cold water inlet slit 203 between the plunger 50 and the upper casing 10, and hot water flows through a hot water inlet slit 204 between the plunger 50 and the lower casing 20. By moving the plunger 50 upwardly or downwardly, the cold water inlet slit 203 and the hot water inlet slit 204 can be adjusted in terms of their sizes, thereby controlling the amount of cold water inflow and hot water inflow. When cold water flowing inside the plunger 50 reaches a temperature sensing area of the paraffin wax temperature sensing component 60 and mixes with hot water, water temperature is sensed by the paraffin wax temperature sensing component 60; because the paraffin wax temperature sensing component 60 expands under high temperature and contracts under low temperature, the plunger 50 is driven to move up or down to realize temperature self-adjustment. When the spline rod 30 is released, the working spring 70 between the plunger 50 and the lower casing 20 drives the plunger 50 to reset. The prior art thermostatic valve has the following disadvantages: 1. At present, the plunger 50 of the prior art thermostatic valve is designed to have an integral structure. When the valve is used in an area where water contains mud and sands, the plunger 50 of the valve will always be clogged because of the mud and sands. As a result, the valve cannot be used. To solve this problem, a filter net 80 is usually required to sleeve the lower casing 20 to prevent mud and sands from clogging the valve core. However, the filter net 80 cannot block mud and sands of tiny size from getting into the valve.
2. A protection spring of the prior art thermostatic valve core using the paraffin wax temperature sensing component 60 to adjust water temperature is usually designed inside the guide rod (part of guiding assembly 40). During use of the valve, the protection spring cannot assist in removing impurities.
3. In the prior art thermostatic valve core, hot and cold water will flow to the temperature sensing area of the paraffin wax temperature sensing component 60 directly after mixing. However, the hot and cold water are usually not further and sufficiently mixed. Therefore, temperature adjustment is not achieved stably.
In view of the aforesaid disadvantages now present in the prior art, the inventor has specifically invented a clogging-proof and jamming-proof thermostatic valve core according to the present invention.
An object of the present invention is to provide a clogging-proof and jamming-proof thermostatic valve core so as to solve the problem of clogged valve core because of mud and sands.
To fulfill the above object, the present invention has the following technical solutions: A clogging-proof and jamming-proof thermostatic valve core, comprising an upper casing, a lower casing, a plunger assembly, a guiding rod, a spline rod, a paraffin wax temperature sensing component and a working spring; the lower casing is provided with a cold water inlet, a hot water inlet, and a mixed water outlet; an axial shaft of the paraffin wax temperature sensing component is axially configured inside the upper casing and the lower casing; the guiding rod is positioned in the upper casing above the paraffin wax temperature sensing component; the spline rod is disposed at an upper end of the upper casing; the spline rod is threadedly connected to the guiding rod which is capable to move up and down.
The plunger assembly comprises a press cap, a connecting sleeve, a plunger upper cap, a plunger seat and a protection spring; both the press cap and the connecting sleeve partially sleeve the paraffin wax temperature sensing component, and are slidable with respect to each other; the press cap is positioned on top of the connecting sleeve and is partially sleeved inside the connecting sleeve; a top portion of the paraffin wax temperature sensing component protrudes out of the press cap; a top portion of the connecting sleeve abuts against the press cap; a bottom portion of the connecting sleeve abuts against the paraffin wax temperature sensing component; water inlet holes are provided in the middle of the plunger upper cap; water outlet holes are provided in the middle of the plunger seat; the plunger seat partially sleeves the plunger upper cap, and are slidable with respect to each other; a top portion of the plunger upper cap abuts against the press cap; a bottom portion of the plunger seat abuts against the connecting sleeve; the protection spring is disposed between the plunger upper cap and the plunger seat; the plunger upper cap, the protection spring and the plunger seat are tightly contained between the press cap and the connecting sleeve; a lower end of the working spring resiliently abuts an inner bottom surface of the lower casing; an upper end of the working spring resiliently abuts a bottom surface of the plunger seat.
A cold water inlet slit corresponding to the cold water inlet is formed between the plunger upper cap and the upper casing; a hot water inlet slit corresponding to the hot water inlet is formed between the plunger seat and the lower casing.
Further, the protection spring sleeves the connecting sleeve.
Further, a water inlet disc is provided inside the plunger upper cap; the water inlet holes are provided on the water inlet disc; the water inlet holes are spaced apart from one another by equal intervals; a water outlet disc is provided inside the plunger seat; the water outlet holes are provided on the water outlet disc; the water outlet holes are spaced apart from one another by equal intervals.
Further, a sealing ring is provided between the plunger upper cap and the plunger seat.
Further, a bottom portion of the guiding rod is sleeved with a press bolt; an upper portion of the press cap is sleeved inside the press bolt; a position limiting flange is provided around an inner surface of the press bolt to limit downward movement of the press cap.
Further, the thermostatic valve core also comprises a water mixing component; the water mixing component is mounted at the mixed water outlet of the lower casing; slanted holes spaced apart from one another by equal intervals are provided on the water mixing component.
To use the present invention, rotate the spline rod to drive the guiding rod to move downwardly; when downward movement of the guiding rod causes the guiding rod to abut against the paraffin wax temperature sensing component, the paraffin wax temperature sensing component will be driven to move downwardly; as the guiding rod continues to move downwardly, the guiding rod will then also abut against the press cap and therefore drive the press cap to move downwardly; the press cap in turns drives the plunger upper cap to move downwardly; as a result, the cold water inlet slit will be enlarged. Due to the effect of the protection spring, the plunger upper cap is required to receive a greater driving force from the press cap in order to be driven to move downwardly; therefore, a larger cold water inlet slit is formed between the plunger upper cap and the upper casing for impurities of large sizes to pass through, so that the impurities will not be jammed between an end surface of the plunger upper cap and an end surface of the upper casing. Also, because driving force that drives the paraffin wax temperature sensing component to move downwardly is buffered by the protection spring, the paraffin wax temperature sensing component is prevented from being damaged due to use of excessive driving force.
When the spline rod is rotated reversely, the guiding rod and the press bolt are driven to move upwardly, and so the connecting sleeve and the press cap are also driven to move upwardly; since the plunger upper cap, the plunger seat and the protection spring are tightly contained between the press cap and the connecting sleeve, the plunger upper cap and the plunger seat will also be driven to move upwardly; also, the working spring compressed by the plunger seat will be decompressed to provide upward driving force to the plunger seat as the plunger seat 34 move upwardly. As a result, the hot water inlet slit is enlarged while the cold water inlet slit is narrowed. Due to the effect of the protection spring, the plunger seat is required to receive a greater driving force in order to be driven to move upwardly; therefore, a larger hot water inlet slit is formed. Since the upwardly driving force against the plunger upper cap is buffered by the protection spring, the cold water inlet slit can maintain a sufficiently large size.
The present invention has the following advantages: 1. Since the plunger seat, the plunger upper cap and the protection spring are tightly contained via the press cap and the connecting sleeve, it is ensured that the plunger upper cap can only be driven to move downwardly under a certain amount of downward driving force, and the plunger seat can only be driven to move upwardly under a certain amount of upward driving force. As a result, a larger cold water inlet slit and a larger hot water inlet slit can be attained. Therefore, impurities of larger sizes can pass through so as to prevent impurities from being jammed in the plunger assembly causing the plunger assembly being clogged. Accordingly, the present invention does not require a filter net, which further prevents clogging of the thermostatic valve core.
2. Compared with a prior art thermostatic valve core using paraffin wax temperature sensing component, the present invention improves and optimizes mixture of hot and cold water. In the present invention, cold water passes through the water inlet holes and the water outlet holes, and then flows down to a hot water zone to be premixed with hot water, and then the pre-mixed hot and cold water will swirl down through the slanted holes on the lower casing where hot and cold water are sufficiently mixed; eventually the sufficiently mixed hot and cold water will flow to a temperature sensing area of the paraffin wax temperature sensing component. As a result, water temperature of the water output by the valve core is more stable.
3. The present invention uses a press bolt to achieve position limitation of the press cap to ensure that the plunger upper cap and the plunger seat move only within a safe stroke with respect to the paraffin wax temperature sensing component to prevent excessive stress on the paraffin wax temperature sensing component causing damage of the paraffin wax temperature sensing component.
4. By adjusting internal dimensions, the present invention is adaptable to be used in a thermostatic valve core made of memory alloy and also in a thermostatic valve core using a paraffin wax temperature sensing component. Therefore, the present invention has good adaptability of use.

The plunger assembly 3 comprises a press cap 31, a connecting sleeve 32, a plunger upper cap 33, a plunger seat 34 and a protection spring 35; both the press cap 31 and the connecting sleeve 32 partially sleeve the paraffin wax temperature sensing component 6, and are mutually slidable with respect to each other; the press cap 31 is positioned on top of the connecting sleeve 32 and is partially sleeved inside the connecting sleeve 32; a top portion of the paraffin wax temperature sensing component 6 protrudes out of the press cap 31; a top portion of the connecting sleeve 32 abuts against the press cap 31; a bottom portion of the connecting sleeve 32 abuts against the paraffin wax temperature sensing component 6; the plunger seat 34 partially sleeves the plunger upper cap 33, and are slidable with respect to each other; water inlet holes 331 are provided in the middle of the plunger upper cap 33; water outlet holes 341are provided in the middle of the plunger seat 34; a top portion of the plunger upper cap 33 abuts against the press cap 31; a bottom portion of the plunger seat 34 abuts against the connecting sleeve 32; the protection spring 35 is disposed between the plunger upper cap 33 and the plunger seat 34; as such, the plunger upper cap 33, the protection spring 35 and plunger seat 34 are tightly contained between the press cap 31 and the connecting sleeve 32; a lower end of the working spring 7 resiliently abuts an inner bottom surface of the lower casing 2; an upper end of the working spring 7 resiliently abuts a bottom surface of the plunger seat 34.
A cold water inlet slit 332 corresponding to the cold water inlet 22 is formed between the plunger upper cap 33 and the upper casing 1; a hot water inlet slit 342 corresponding to the hot water inlet 23 is formed between the plunger seat 34 and the lower casing 2.
To increase the stability of the protection spring 35 when being mounted, the protection spring 35 sleeves the connecting sleeve 32.
Further, a water inlet disc 333 is provided inside the plunger upper cap 33; the water inlet holes 331 are provided on the water inlet disc 333; the water inlet holes 331 are spaced apart from one another by equal intervals; a water outlet disc 343 is provided inside the plunger seat 34; the water outlet holes 341 are provided on the water outlet disc 343; the water outlet holes 341 are spaced apart from one another by equal intervals.
To increase the sealing effect of the plunger assembly 3, a sealing ring 8 is provided between the plunger upper cap 33 and the plunger seat 34.
As a preferred embodiment, a bottom portion of the guiding rod 4 is sleeved with a press bolt 41; an upper portion of the press cap 31 is sleeved inside the press bolt 41; a position limiting flange is provided around an inner surface of the press bolt 41 to limit downward movement of the press cap 31; by limiting the movement of the press cap 31 using the press bolt 41, the plunger upper cap 33 and the plunger seat 34 are ensured to move only within a safe stroke with respect to the paraffin wax temperature sensing component 6 to prevent excessive stress on the paraffin wax temperature sensing component 6 causing damage of the paraffin wax temperature sensing component 6.
As a preferred embodiment, the thermostatic valve core also comprises a water mixing component 9. The water mixing component is mounted at the mixed water outlet 21 of the lower casing 2; slanted holes 91 spaced apart from one another by equal intervals are provided on the water mixing component 9. After cold water flows through the water inlet holes 331 and the water outlet holes 341, the cold water is pre-mixed with hot water at a hot water zone at a lower portion of the valve core, and then the premixed water will then swirl down through the slanted holes 91 of the lower casing 2 so as to be mixed sufficiently. The sufficiently mixed water will flow to the temperature sensing area of the paraffin wax temperature sensing component 6; therefore, the water output from the valve core will have a more stable temperature.
To use the present invention, rotate the spline rod 5 to drive the guiding rod 4 to move downwardly; when downward movement of the guiding rod 4 causes the guiding rod 4 to abut against the paraffin wax temperature sensing component 6, the paraffin wax temperature sensing component 6 will be driven to move downwardly; as the guiding rod 4 continues to move downwardly, the guiding rod 4 will then also abut against the press cap 31 and therefore drive the press cap 31 to move downwardly; the press cap 31 in turns drives the plunger upper cap 33 to move downwardly; as a result, the cold water inlet slit 332 will be enlarged. Due to the effect of the protection spring 35, the plunger upper cap 33 is required to receive a greater driving force from the press cap 31 in order to be driven to move downwardly; therefore, a larger cold water inlet slit 332 is formed between the plunger upper cap 33 and the upper casing 1 for impurities of large sizes to pass through, so that the impurities will not be jammed between an end surface of the plunger upper cap 33 and an end surface of the upper casing 1. Also, because driving force that drives the paraffin wax temperature sensing component 6 to move downwardly is buffered by the protection spring 35, the paraffin wax temperature sensing component 6 is prevented from being damaged due to use of excessive driving force.
When the spline rod 5 is rotated reversely, the guiding rod 4 and the press bolt 41 are driven to move upwardly, and so the connecting sleeve 32 and the press cap 31 are also driven to move upwardly; since the plunger upper cap 33, the plunger seat 34 and the protection spring 35 are tightly contained between the press cap 31 and the connecting sleeve 32, the plunger upper cap 33 and the plunger seat 34 will also be driven to move upwardly; also, the working spring 7 compressed by the plunger seat 34 will be decompressed to provide upward driving force to the plunger seat 34 as the plunger seat 34 move upwardly. As a result, the hot water inlet slit 342 is enlarged while the cold water inlet slit 332 is narrowed. Due to the effect of the protection spring 35, the plunger seat 34 is required to receive a greater driving force in order to be driven to move upwardly; therefore, a larger hot water inlet slit 332 is formed. Since the upwardly driving force against the plunger upper cap 33 is buffered by the protection spring 35, the cold water inlet slit 332 can maintain a sufficiently large size.
A specific embodiment of the present invention is described above. However, the scope of protection of the present invention should not be limited by the above description. Any configurations achieving equivalent technical effects in accordance with the inventive concept of the present invention should also fall within the scope of protection of the present invention.
