Abstract
The invention discloses a water temperature and a water level sensor, and in particular relates to a sensor for measuring a liquid level or a liquid amount on a liquid tank according to liquid pressure. The pressure type liquid level and temperature integrated sensor is provided for detecting change of water pressure in a water tank. The pressure type liquid level and temperature integrated sensor comprises a valve body, a valve core, an insulator pad, an insulation sleeve, a conductive silicon rubber combined body, a substrate and a circuit board and has the characteristics of convenience in use, simple structure, long service life and the like.
Description
Technical field
The present invention relates to a kind of water temperature, level sensor, especially a kind of sensor that passes through liquid pressure measurement liquid level or amount of liquid on the fluid box that is used in.
Background technology
The water level and the cooling-water temperature sensor that use now are various in style, a kind of electric pole type water-temperature water-level sensor is disclosed in the patent of patent No. ZL01217122, the water level of the detection described in this patent has level relatively, the water level that shows corresponding a plurality of gears on the corresponding display, the level that has such as the similar type such as 20%, 50% shows, can not detect along with the variation of solar water heater water tank middle water level in real time respective change.This fuzzy detection method more and more can not satisfy our requirement, and so fuzzy demonstration tends to cause having washed half, and hot water has not had.The level sensor of kind electrode formula causes manufacturing cost higher because manufacturing process is complicated.
Also have now and a kind ofly measure the pressure type sensor of liquid level by tracer liquid pressure, described liquid is oil, water etc., the pressure type sensor that uses now since with the easy scaling in the contacted spool of liquid place or dirt so that detect inaccurate; And present sensor can leak, and especially uses easier generation leakage phenomenon in solar water heater because in the spool long time treatment high-temperature water, is connected with the cooperation place of spool all parts tight due to.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the pressure type liquid level temperature integrative sensor that provides a kind of energy to change by detecting Water in Water Tanks pressure.
Pressure type liquid level temperature integrative sensor of the present invention, it comprises valve body, spool, insulator pad, insulation sleeve; Described spool is T-shaped, is provided with successively on the described valve body and spool, electric silica gel complex, cushion block, wiring board; Described valve body is provided with the T-shaped cavity that cooperates with spool, described have projection with the contacted spool end of electric silica gel complex, described projection is right cylinder, and overlap with the axial line of spool, fluted on the sidewall periphery of the valve body of this projection correspondence, described circlip is arranged on the outer circumference surface of projection, and embeds in the groove of valve body, and the liquid that plays the spool outside can not be seeped in the valve body chamber by this circlip; Described electric silica gel complex outside is coated with the insulation glue-line of Waterproofing/oilproofing; Described cushion block contacts with the electric silica gel composite bulk phase, described electric silica gel complex and cushion block valve body place cavity internal diameter corresponding to contravention that join increases, be that described valve body place has a platform, cushion block is positioned on this platform, so that cushion block can not move toward the spool direction; Described cushion block is fixed on the valve body by the resilient seal back-up ring, and is fluted on the described valve interior wall, is provided with described resilient seal back-up ring in the groove, thereby plays the fixedly effect of cushion block; Described wiring board and cushion block link into an integrated entity, and they connect by holder; Be provided with pressure signal line in the described electric silica gel complex, signal wire is connected with wiring board; Be provided with thermal sensing element in the described electric silica gel complex, thermal sensing element is connected with wiring board by wire; Described wiring board is provided with draws wire, draws wire and passes waterproof gland cover; Described waterproof gland cover is connected with valve body so that this end sealing; The valve body that described spool is corresponding with the liquid contact jaw is provided with limiting stand, limiting stand so that spool can not move toward flow direction.
In order to make on the valve body inlet opening place not precipitate dirt, as preferably, the inlet opening of the valve body corresponding with the contacted spool end of liquid is horn-like.
According to above-described pressure type liquid level temperature integrative sensor, as long as it cooperate with corresponding display controller, with regard to the very easy amount of measuring liquid in the casing, simultaneously, the temperature and pressure data acquisition is that a setting is on the element, avoid the generation of the warm phenomenon of wafing, improved accuracy rate, reduced the error of data; It has the characteristics such as easy to use, simple in structure, long service life.
