Description
Affiliated technical field
The utility model relates to a kind of water level sensor for solar water heater, belongs to liquid level detector.
Background technology
At present, the level sensor of China's solar water heater use is of a great variety.As: resistance induction type, its principle of work are to utilize the electric conductivity of water to measure water level, because the easy scaling of sensor surface, and incrustation scale is moisture, causes the level measuring mistake; And for example: the ball float induction type level sensor that current line occurs in the industry, its principle of work is: ball float rises and falls with the water surface and lifting, and driving ball float conductive bar rectilinear motion, the ball float conductive bar drives and is positioned at the outer rheostat of boiler, thereby water level signal is become electric signal.There is potential problem in this sensor,, measures main part (rheostat) outside boiler that is, and when using in the winter time, the ball float conductive bar outside boiler partly can be frozen because of water vapor enters, and makes that guide rod can not proper motion.
China's utility model 00206793.5 proposes a kind of diaphragm induction type liquid level sensor, its principle of work is: the pressure of liquid level acts on the pressure-sensitive diaphragm, the variation of liquid level causes that the pressure on the pressure-sensitive diaphragm changes, under the effect of pressure and spring force, pressure-sensitive diaphragm drives the pen travel of linear sliding potentiometer; Pressure-sensitive diaphragm moves up and down with the variation of liquid level, drives the pen travel of linear sliding potentiometer, thereby liquid level signal is become electric signal.The advantage of this diaphragm induction type liquid level sensor is: simple in structure, and highly versatile; Shortcoming is: when it was used for solar water heater, incrustation scale entered sensor easily, influenced moving of diaphragm, and liquid level sensor is produced than mistake.
Summary of the invention
The purpose of this utility model is: overcome above-mentioned defective, the sensor of a kind of long service life, anti-freeze, antiscale is provided.
A kind of water level sensor for solar water heater that the utility model proposes is made up of slide bar, pressure spring, top board, pressure-sensitive diaphragm, lower platen, rheostat, upper shell and lower house; Cause top board and lower platen compress sealing in the described pressure-sensitive diaphragm, and are fixed on the slide bar bottom, and outer cause upper shell of pressure-sensitive diaphragm and lower house compress sealing and fixing; The slide bar lower end drives described rheostatic pen travel; It is characterized in that: described slide bar upper end is fixed with the antiscale cap; Pressure spring is enclosed within on the slide bar, and pressure spring one end withstands the antiscale cap, an end is supported by the connecting pipe tube wall; Pressure spring is installed in the connecting pipe with slide bar, leaves the slit between the outer wall of antiscale cap and connecting pipe, and the pressure of water level reaches connecting pipe by the slit between the outer wall of antiscale cap and connecting pipe, remakes to be used on the pressure-sensitive diaphragm.
Antiscale cap in the utility model is fixed on the top of slide bar, the antiscale cap is directly over the pilot mouth of pipe, leave the slit between the outer wall of antiscale cap and connecting pipe, so, incrustation scale can not be deposited in the connecting pipe, and can be slipped to the bottom along the antiscale cap, but hydraulic pressure can enter connecting pipe from the slit between antiscale cap and the connecting pipe, remakes to be used on the pressure-sensitive diaphragm.
The variation of water level causes that the pressure on the aforementioned diaphragm changes, and under the effect of pressure and spring force, slide bar moves up and down with the variation of water level, drives the pen travel of linear sliding potentiometer, thereby water level signal is become electric signal.
Be convenient in solar water heater mounting temperature sensor, can be in described slide bar mounting temperature sensor.Thereby described level sensor can also play the effect of temperature sensing.
When in use, sensor integral body is in the water tank skin, thereby sensor can be incubated, and can not freeze.
Effect of the present utility model is: can prevent that incrustation scale from entering sensor, preventing that sensor from freezing, long service life.
Description of drawings
Fig. 1 is the texture edge figure of level sensor.
Among Fig. 1,1-antiscale cap; The 2-slide bar; The 3-pressure spring; The 4-top board; The 5-pressure-sensitive diaphragm; The 6-lower platen; The 7-rheostat; The 8-upper shell; The 9-lower house; The 10-bolt.The 11-slit; The 12-pointer.
Embodiment
With reference to Fig. 1, the level sensor of present embodiment is made up of antiscale cap 1, slide bar 2, pressure spring 3, top board 4, pressure-sensitive diaphragm 5, lower platen 6, rheostat 7, upper shell 8 and lower house 9, wherein slide bar 2 is the hollow tubular of upper end closed, puts into temperature sensor in the hollow tubular; Cause top board 4 and lower platen 6 compress sealing in the described pressure-sensitive diaphragm 5, and are fixed on slide bar 2 bottoms, and pressure-sensitive diaphragm 5 outer cause upper shells 8, lower house 9 compress sealing and fixing, and upper and lower pressing plate has bolt 10 fixing; The pointer 12 that slide bar 2 lower ends drive described rheostat 7 moves.
Antiscale cap 1 in the present embodiment is fixed on the top of slide bar 2, antiscale cap 1 directly over the pilot mouth of pipe, antiscale cap 1 and the connecting pipe outer wall between slit 11 is arranged, so the incrustation scale that water produced can not enter in the connecting pipe, can be slipped to the bottom along antiscale cap 1; And hydraulic pressure can enter connecting pipe from the slit 11 between antiscale cap 1 and the connecting pipe outer wall, conducts.
Sensor integral body is in the water tank skin, thereby sensor can be incubated, and can not freeze.
The variation of water level causes that the pressure on the aforementioned pressure diaphragm 5 changes, and under the effect of pressure and spring force, slide bar 2 moves up and down with the variation of water level, and the pointer 12 that drives linear sliding potentiometer moves, thereby water level signal is become electric signal.
Owing in slide bar 2, temperature sensor is housed, so described level sensor can also play the effect of temperature sensing.
The sensor has been realized two kinds of functions, measures the temperature of water level and water simultaneously.Is temperature sensor and level sensor collection one, reduces production costs, and is convenient to install.
