The utility model discloses a component device for detecting the liquid level of a container. It is mainly composed of a housing, a magnetic float and an inductive element. It is characterized in that the said float is set in the lumen of a measuring tube. Inductive elements and circuit boards are arranged on the outer wall of the pipe wall, and the inductive elements are arranged in sections corresponding to the positions of the magnets in the float. The problem of short working life of the liquid level sensor is fundamentally solved by adopting the structural mode of indirect detection. It is suitable for various occasions of different containers and liquid level detection including solar water heaters.
Description
The utility model relates to level gauging, specifically a kind of Level Detection part device with buoy control detection signal.
Usually detecting liquid level is to reflect the electric signal of liquid level and further realize control in order to obtain.These controls comprise feed liquor amount and timing controlled thereof.A kind of sensing rod that is used for solar water heater water tank container detection liquid level before this, insert water tank by vent port, directly place water liquid, suspension operational inconvenience not only, also influence accuracy because of producing incrustation scale easily, and the surface of its measuring point head easily because of electrolysis takes place, oxidation damages, its mission life is shorter, generally below 1 year.
The purpose of this utility model is to propose a kind of novel liquid level pick-up unit, and it can fundamentally solve the short problem of its mission life with the frame mode of indirect detection.
The purpose of this utility model is achieved in that this novel liquid level pick-up unit, main float and sensing element by housing, magnetic, it is characterized in that said float is located in the tube chamber of a survey pipe, the lower end of surveying pipe is provided with the port joint, the external storage liquid container of port joint, the tube wall outer wall of surveying pipe is provided with sensing element and wiring board thereof, and the sensing element segmentation is provided with, and is corresponding with the magnet positions in the float.
In the said housing, the upper end of surveying the pipe tube chamber is provided with capping and air hole, also is provided with the operation circuit panel assembly in the cap at wiring board place and the cap chamber.
Said port joint connects to chew with an elbow and is connected, and elbow connects connecing of chewing and chews that end is unsettled to be inserted into the chewing in the mouth an of three-way connection, in its end sealing and fixing.
Connect the back of chewing at said elbow and be provided with one and be used for the thermometric thermal resistance, its gauge head passes from connecing the space of chewing inner chamber.
Owing to use magnetic float independent the survey in the pipe, surveying between pipe and sensing element has tube wall to separate, make sensing element and wiring board be in one not with good working environment that liquid contacts among, mission life obtains prolonging widely, degree of accuracy also is improved, thereby has guaranteed the accuracy of liquid level data.In addition, the contrary feed liquor three-port structure that returns formula of employing can make this pick-up unit and feed liquor threeway merge installation and be unlikely to cause the indeterminacy phenomenon.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a shape assumption diagram of the present utility model.
Fig. 2 is a structure principle chart of the present utility model.
Fig. 3 is an embodiment synoptic diagram of the present utility model.
Fig. 4 is two the structural representation of the utility model embodiment.
As shown in Figure 1, this is a basic structure of the present utility model.The 1st, the housing of elongate tubular is provided with one of the semilune tube chamber and surveys and survey pipe, and the back interlocks side by side with a cap, establishes port joint 2, the external formation linker of port joint and liquid container, the built-in magnetic float 3 of tube chamber below the tube chamber of this survey pipe.Segmentation is provided with sensing element in the wall casing cover of the chamber of tube chamber.The various Versatile induction switch elements that comprise the magnetic red pipe all can.
Fig. 2 is the decomposition chart of liquid level detection device.Wherein 2 is port joints.The 3rd, float, the centre is embedded with magnetic 4, and there is capping 6 upper end of pipe 5, and its next door is provided with air hole, floats in order to guarantee the normal of float.Be equipped with wiring board 7, set up sensing element 8 on its face separately.Wiring board is inserted upright along the tube chamber outer wall.Be provided with corresponding control circuit panel assembly 10 in the cap 9, cap 9 is fastened on to be surveyed on the pipe 5, below the socket (as quartzy socket) of 11 expression external lead wires.
Fig. 3 is the embodiment of a practical application.Near the lower portion of water tank 16 intake-outlet 12 is housed, liquid level detection device 14 and elbow connect to be chewed 15 and joins, and will connect then and chew on the water tank wall that directly is connected on away from intake-outlet.The 13rd, the vent port of water tank.
Threeway with liquid level detection device and intake-outlet among the embodiment of Fig. 4 is connected on one.Like this, can influence liquid level detection device middle water level undesired variation in next door when avoiding into water, water outlet and cause the actual water level in control signal and the water tank inconsistent, so adopted the feed liquor three-port structure of contrary time formula.As shown, the direct water receiving case of the three-way connection at intake-outlet 12 places, cross-under has the elbow of liquid level detection device to connect to chew in the three-way connection, and the mouth 19 of chewing of the three-way connection of Qi Zui hole 20 and intake-outlet 12 interlaces and separates a distance.In connecing and chew, elbow also is provided with the thermal resistance 18 that detected temperatures is used.The 21st, gauge head (thermal resistance).So, enter the water liquid of surveying pipe and the water-in and water-out mouth of pipe not at same place, just can not cause when water inlet, water outlet surveying that water level produces sharply variation in the pipe.
The device that the technical program provides is in the different vessels, and the Level Detection of different liquids all is suitable for.
