Description

Push-type water valve

This creation is about a water supply device, especially a water supply device installed at the outlet end of a pipeline.

At present, the traditional water pipe control valve in the general market is installed above the water pipe faucet. Although it has the advantage of a simple structure, people must lift their hands to operate the control valve located above the water pipe faucet after completing the washing action. This water shut-off action will cause waste of water resources.

Therefore, a water valve (such as Taiwan Invention Patent Case No. I228578) is currently developed, which is directly installed at the water outlet end of the water pipe and controls the water outlet and water shutoff by pressing the control mechanism. People can operate according to demand and have Water and easy to use. However, at the moment the water is turned off, the water flow in the water pipe may still flow toward the outlet end, and the kinetic energy generated by the flowing water will be converted into elastic energy, which will generate a series of positive and negative pressure waves and oscillate back and forth in the water pipe until The energy stops because of friction. This phenomenon can cause harsh noise and damage to the water pipe when the water is turned off.

In view of this, it is an urgent problem for the industry to provide a better improvement solution.

The main purpose of this creation is to provide a push-type water valve with a buffer structure, which can mitigate the impact force generated when the user turns off the water.

In order to achieve the above purpose, the push-type water valve provided by this creation has: An inlet seat has: an upper seat having: a first flow passage that runs through the center of the upper seat in the up-down direction; and a plurality of second flow passages that communicate from the lower surface of the upper seat to the upper seat. A side surface; a lower seat located below the upper seat, the lower seat having a perforation, and a circulation space formed between the lower seat and the upper seat; a movable plug that can be displaced up and down in the circulation space, and has a circulation A through hole that penetrates the movable plug in the up-down direction; and a control mechanism having a plug portion that closes or opens the perforation according to user control; wherein when the plug portion of the control mechanism opens the When perforating, the movable plug is located below the circulation space; when the plug portion of the control mechanism closes the perforation, the water flowing into the circulation space will gradually push against the lower part of the movable plug against the upper seat. Surface, and close the second flow channels.

Therefore, the advantage of this creation is that the water pressure will be gradually pushed to the closed position of the second flow path by the water pressure when the plug is closed in the water. Compared with the prior art, the flow path is closed when the water is closed, which can effectively reduce the flow of water. The positive and negative pressure waves that will be generated at the moment of stopping, so as to avoid the harsh noise and damage to the water pipe caused by excessive vibration of the water pipe. With the progressive water shutoff function, the water pressure exerts less force on the control mechanism, so the force required to operate is smaller, and the operation is easier and more convenient. In addition, in this creation, the movable plug is displaced and closed by the hydraulic pressure, instead of being deformed to close the flow channel. Therefore, there is no way to reliably close the flow channel due to the aging and hardening of the gasket. problem.

The water passing groove 232 is located on the lower surface of the movable plug 23. In this embodiment, the water passing groove 232 is radial and extends outward from the center of the lower surface of the movable plug 23 or extends outward with the circulation hole 231 as the center. The water passing tank 232 can be used to guide the direction of water flow so that water can reach the periphery of the movable plug 23.

Please refer to FIGS. 2 to 4. The control mechanism 30 is disposed below the water inlet seat 20 and is disposed in the casing 10 but partially exposed on the casing 10. The user can operate a part of the control valve 30 exposed on the casing 10 to control the water valve to close or open the perforation of the lower seat 22. 221. Specifically, the control mechanism 30 includes a movable member 31 and an operation assembly 32. The movable member 31 may be located in a first position and a second position, and the first position is lower than the second position. When the movable member 31 is in the first position, the control mechanism 30 opens the perforation 221 of the lower seat 22; when the movable member 31 is in the second position, the control mechanism 30 closes the perforation 221. The operation assembly 32 is located below the movable member 31 and is used to control the position of the movable member 31. The operation assembly 32 has an operation member 321, an operation base 322, and an elastic member 323.

Please refer to FIG. 5 together. The spacer ring on the inner wall surface of the operation seat 322 is provided with a plurality of protruding ribs 3221, and a plurality of guide grooves 3222 are provided between the protruding ribs 3221. In other words, the ribs 3221 and the guide grooves 3222 are staggered. The top surface of the raised rib 3221 is an inclined surface.

The operation member 321 is disposed in the operation seat 322, and the bottom end of the operation member 321 protrudes outside the operation seat 322 and the casing 10, so the user can directly press the operation member 321. However, other components may be connected to the operation member 321 to allow the user to drive the operation member 321 by triggering other components. Operator 321 A plurality of guide blocks 3211 protrude from the upper side, and the guide blocks 3211 are received in the guide grooves 3222 of the operation base 322. The top surface of each guide block 3211 is an inclined surface, and the direction of the inclined surface of the guide block 3211 is the same as the direction of the inclined surface of the rib 3221.

The operating member 321 has a moving stroke in the up-and-down direction, and when the operating member 321 moves within the moving stroke, the guide blocks 3211 are all located in the guide groove 3222 of the operating base 322, so the operating member 321 and the operating base 322 are not opposed Turn. However, when the operating member 321 is located at the top of the moving stroke, the inclined surface of the guide block 3211 protrudes from the convex rib 3221 and pushes upward against the movable member 31. The elastic member 323 is disposed in the operation base 322 and exerts a downward force on the operation member 321 to keep the operation member 321 at the bottom end of the moving stroke. However, through the weight of the operation member 321 itself, the operation member 321 can also naturally fall back to the bottom end of the moving stroke.

The movable member 31 has a plug portion 311 and a plurality of positioning blocks 312. The plug portion 311 closes or opens the perforation 221 of the lower seat 22 according to user control. Specifically, the upper end of the plug portion 311 is cup-shaped, and has a side wall surrounding the cylindrical portion 222. The cup-shaped plug portion 311 is sleeved on the outside of the cylindrical portion 222 and closes the perforation 221 according to user control.

The positioning block 312 protrudes from the periphery of the movable member 31. The bottom end of the positioning block 312 is an inclined plane, and the direction of the inclined plane of the positioning block 312 corresponds to the inclined plane of the guide block 3211. In other embodiments, the plug portion 311 of the movable member 31 may not be cup-shaped, but a column or block, and may block and close the perforation 221 according to user control.

When the movable member 31 is in the first position, the positioning block 312 is located in the guide groove 3222 of the operation seat 322 and on the guide block 3211 of the operation member 321. At this time, the plug portion 311 is located below the cylindrical portion 222 of the lower seat 22. There is a gap between the plug portion 311 and the cylindrical portion 222. In other words, at this time, the control mechanism 30 opens the perforation 221 of the lower seat 22 (as shown in FIG. 3).

When the movable member 31 is located at the second position, the positioning block 312 is located on the convex rib 3221 of the operation base 322, and at this time, the plug portion 311 is sleeved and closely fits the lower end of the cylindrical portion 222. Surround the sleeve through the plug 311 Provided in the cylindrical portion 222, the movable member 31 can reliably seal the perforation 221. In other words, at this time, the control mechanism 30 closes the perforation 221 (as shown in FIG. 4).

When the user presses the operating member 321, the operating member 321 moves upward and is located at the top of the moving stroke, and the inclined surface of the guide block 3211 of the operating member 321 is pushed against the inclined surface of the positioning block 312 of the movable member 31, so that the movable member 31 is upward Disengage from the operation base 322 and rotate according to the inclined direction of the guide block 3211 and the positioning block 312. When the user releases the operation member 321, the operation member 321 moves downward due to gravity or is pushed down by the elastic member 323 and is located at the bottom of its stroke, and the positioning block 312 of the movable member 31 is located in the guide groove of the operation base 322 3222 (that is, the first position, as shown in FIG. 3) or the inclined surface of the rib 3221 of the operation base 322 (that is, the second position, as shown in FIG. 4).

By pressing the operating member 321 to rotate the movable member 31, the positioning block 312 is sequentially switched on the ribs 3221 and the guide grooves 3222 that are arranged in a staggered manner. That is, the switchable movable member 31 is located in the first position or the second position.

As shown in FIG. 3, when the plug portion 311 of the control mechanism 30 opens the perforation 221 of the lower seat 22 (that is, when the movable member 31 is located at the first position), water can pass from the water inlet of the housing 10 through the first flow passage of the upper seat 21 211 flows into the circulation space. Then most of the water will flow into the space between the casing 10 and the water inlet seat 20 through the second flow channel 212, and then flow out of the water valve through the water outlet of the casing. A small part of water flows into the circulation space below the movable plug 23 through the narrow circulation hole 231, and flows out of the circulation space through the perforation 221 of the lower seat 22. At the same time, the movable plug 23 is pushed downward, and then the water outlet of the casing Out of water valve. Therefore, the movable plug 23 is located below the circulation space and keeps the second flow channel 212 open, and the water valve is in an open state.

As shown in FIG. 4, when the plug portion 311 of the control mechanism 30 closes the perforation 221 of the lower seat 22 (that is, when the movable member 31 is located at the second position), initially the second flow channel 212 is still kept in an unblocked state, and water is still available. Continuously drain the water valve. However, because the perforation 221 of the lower seat 22 is closed, the water flowing into the circulation space cannot be discharged downwards, so the water gradually accumulates in the circulation space and gradually pushes upwards. The movable plug 23 is closed until the movable plug 23 abuts on the lower surface of the upper seat 21 and closes the second flow path 212 to complete the water closing action.

At the same time, through the water tank 232 of the movable plug 23, water can flow along the water tank 232 to the periphery of the movable plug 23 and provide upward pressure to ensure that the movable plug 23 can abut against the first surface of the lower surface of the upper seat 21.二流 道 212. The water valve is now closed.

Please refer to FIG. 10 and FIG. 11. The water valve further has a deforming member 40, which has elasticity and is disposed in the casing 10 and is located above the upper seat 21. The deforming member 40 is used to control the amount of water flowing into the water valve, so as to keep the water output of the water valve stable. The deforming member 40 has a central portion 41 and a peripheral edge portion 42 surrounding the periphery of the central portion 41.

Please refer to FIG. 7 together. The central portion 41 has a central hole 411. The central hole 411 communicates with the first flow path 211 of the upper seat 21 and has a common axis with the first flow path 211. The peripheral edge portion 42 further includes a plurality of flow increasing holes 421 and a plurality of bumps 422. The flow increasing holes 421 are scattered around the central hole 411 and face the upper surface of the upper seat 21. The bump 422 is located on the lower surface of the peripheral edge portion 42 and abuts on the upper surface of the upper seat 21, so that the lower surface of the peripheral edge portion 42 is spaced from the upper surface of the upper seat 21.

When the water pressure flowing through the water valve is small, in addition to the water flowing through the central hole 411 into the first flow path 211, since the flow increasing hole 421 communicates with the first flow path 211 of the upper seat 21, water can also pass through the increasing flow hole 421 through the upper seat 21 The upper surface flows into the first flow path 211. When the water pressure flowing through the water valve is large, the deformation member 40 is deformed under pressure (as shown in FIG. 11), the peripheral edge portion 42 is bent downward and the central portion 41 abuts against the peripheral edge of the first flow path 211, and is blocked The flow increasing hole 421 is in communication with the first flow path 211.

Therefore, when the water pressure is small, water can flow into the water valve through the central hole 411 and the flow increasing hole 421; when the water pressure is large, the flow increasing hole 421 is almost blocked, so that water can flow into the water valve only through the central hole 411. Under the influence of water pressure and the area of the flow channel, even if the water pressure of the water source changes, the amount of water flowing out of the water valve can remain stable without significant changes.

Please refer to FIG. 2 and FIG. 3. The water valve may further include a bubble head 50, a bubbler net 60 and a strainer 70.

The foaming head 50 is located in the casing 10 and has a plurality of gaps with the casing 10, and the control mechanism 30 penetrates and protrudes from the bottom of the foaming head 50. The side wall of the bubble head 50 has a first surface, and a plurality of air inlet holes 51 are arranged at intervals on the first surface. Each air inlet hole 51 communicates with a gap between the casing 10 and the bubble head 50. The bubble head 50 has a water outlet 52 in the shape of a radial grid at the bottom.

When the perforation 221 of the lower seat 22 is opened, the water flowing out from the second flow channel 212 will flow into the bubble head 50 and flow out of the water valve through the water outlet hole 52. When water flows through the foaming head 50, air will flow into the air inlet 51 from the gap between the casing 10 and the foaming head 50, and mix with water. After passing through the radiation grid-shaped water outlet holes 52, the air mixed into the water will be dispersed into fine foam. In order to make the foam more detailed, the foaming net 60 can be set in the foaming head 50. Specifically, the foaming net 60 is located above the water outlet hole 52, and the control mechanism 30 runs through the center of the foaming net 60.

The filter screen 70 is disposed at the upper end of the water valve, specifically, it is disposed above the upper seat 21 or the deformed member 40 to filter impurities when water flows into the water valve, so as not to block the water valve with the impurities.

The advantage of this creation is that the movable plug 23 will be gradually pushed to the position of the closed second flow channel 212 by the water pressure when the water is turned off, which can effectively reduce the positive and negative pressure waves generated when the water stops momentarily, thereby avoiding Excessive vibration of the water pipe causes harsh noise and damage to the water pipe. With the progressive water shutoff function, the water pressure exerts less force on the control mechanism 30, so the force to be applied during operation is smaller, and the operation is easier and more convenient. In addition, in this creation, the movable plug 23 is displaced by water pressure to close and close the flow channel, instead of being deformed to close the flow channel by water pressure. Therefore, the flow cannot be closed due to the aging or hardening of the gasket. Question of the road.

The above is only the preferred embodiment of the creation, and does not limit the creation in any form. Although the creation has been disclosed as above with the preferred embodiment, it is not intended to limit the creation. Generally knowledgeable people, without departing from the scope of this creative technical solution In addition, when the technical contents disclosed above can be used to make some changes or modifications to equivalent equivalent embodiments, any content that does not depart from the technical solution of this creation can be made according to the technical essence of this creation.
