Description

Solar water heater water level proving installation

Technical field the utility model relates to a kind of water level proving installation, a kind of specifically solar water heater or family expenses water tower level proving installation of being used for.

The background technology solar water heater is the commercial device that China widelys popularize and comparatively popularizes, the water level testing sensor of prior art, conducting is to be that insulation between conductor, electrode, sealing are material with the heat-shrink tube with water between electrode, when common electrode one by one with certain grade of electrode through the water conducting or when separating, the water level display instrument is to showing current water level by a shelves electrode.Because of the temperature variation of water temperature in the solar water heater water tank bigger, when water temperature greater than more than 80 ℃ the time, water tank upper end humidity is bigger, can produce between electrode and gang up phenomenon, water level is shown entanglement takes place, because insulation, the sealing of level sensor, relying on heat-shrink tube guarantees, but electrode is a metal material, differs bigger with the heat-shrink tube expansion coefficient, at solar water heater water tank during anhydrous or exsiccosis, temperature is higher in the water tank, about about 100～150 ℃, high temperature causes the level sensor sealing to decrease, and inner inlet can't normally use; In the relatively poor area of water quality, level sensor such as long period of soaking are in water, and incrustation scale makes between electrode and gangs up, water level display instrument generation entanglement.Thus, the suitable fouling of traditional level sensor, difficult sealing, serviceable life is short, maintenance rate is high, and its reliability and stability are poor.

Utility model content the purpose of this utility model is to overcome the defective of above-mentioned prior art, provides a kind of water quality, water temperature of not being subjected to influence, and reliability and stability are good, the solar water heater water level proving installation of long service life.

To achieve these goals, the technical scheme that the utility model is taked is: a kind of solar water heater water level proving installation is characterized in that: this proving installation is made up of float, guiding float, master arm, support, trace, slave arm, magnet strip and reed switch circuit plate; One end and the master arm of support are hinged, and the other end and slave arm are hinged, and the other end of master arm is fixedlyed connected with float, and the other end of float is hinged with the guiding float, and the other end of slave arm installs magnet strip; The reed switch circuit plate is made up of web joint and several tongue tubes that are installed on the web joint, and web joint is fixed on the support, and magnet strip is corresponding with the tongue tube position; The two ends of trace are hinged with master arm and slave arm respectively.

In order to ensure safe in utilization and attractive in appearance, neat, the link of reed switch circuit plate, slave arm and magnet strip, trace and support and slave arm is encapsulated in housings.

The utility model is a water level height in the corresponding water tank of power arm by float, utilize buoyancy to be power,, make corresponding adhesive of tongue tube or release through the displacement of trace driving-belt moving magnet bar, thereby reach the purpose of test water level height, show current water level through the water level display instrument.

Principle of work of the present utility model: establish buoyancy greater than the master arm driving force, float and master arm deadweight sum make float sagging naturally greater than the resistance sum.Separate with tongue tube at the anhydrous situation lower magnet of water tank bar, the water level display instrument shows exsiccosis.Along with the rising of water level, under the guiding of guiding float, float drives master arm and rises during last water, through the trace transmission, drives slave arm and makes the magnet strip displacement, and when magnet strip is displaced to the corresponding adhesive of certain grade of tongue tube, limnimeter shows current water level.During decline of water table, because float master arm deadweight sum makes float sagging naturally greater than the resistance sum, drive slave arm, magnet strip is shifted in the other direction, corresponding tongue tube discharges naturally, and limnimeter shows current water level.

In addition, change magnet strip into the navigation bar, tongue tube changes limit switch into, and the mobile navigation bar makes limit switch conducting one by one, also can realize the water level test.

Because of the utility model is the dynamic test water level device with buoyancy, the fluctuating of float does not have related with incrustation scale, water temperature, thoroughly solved in the test of solar water heater water level big because of sealing difficulty, big and the defective brought of incrustation scale influence, have simple in structure, reliability and stability good, the advantage of long service life.The utility model also can be used for family expenses water tower level measuring.
