Abstract
The utility model relates to a water level and water temperature detector for a solar water heater, which is mainly characterized in that one end of an outer tube 12, which is assembled with a shaft frame 4, is inserted in a water tank, and the other end is fixed with a switching box 11; outside the water tank, a pull wire 5 passing through the outer tube transfers the motion of a float 1 following a water level to a swinging element 7 in the switching box 11, which causes the swinging element 7 to move; according to the motion of the swinging element 7, different converting circuits are matched and the measurement to the water level can be realized. During the detection process of the water level, the float 1 and water have no electric relation, and thus water temperature and water quality can not affect the detection; therefore, the service life is effectively prolonged and the failure rate is reduced. Meanwhile, a hose 6 containing a temperature measuring element realizes the measuring function to water temperature. The utility model has the characteristics of convenient installation, stable performance, simple structure, long service life, etc., and can be used for detecting liquid level and liquid temperature in other liquid storing tanks.
Description
Affiliated technical field
The utility model relates to a kind of utensil of while sensed water level water temperature.It is a kind of solar water heater's of being specially adapted to water level and temperature detector.
Background technology
Following three kinds of modes have mainly been adopted in the detection of known solar water heater's water level.1, electric pole type: utilize the electric conductivity of water, electrode is arranged on positions different in the water, be used for detecting corresponding water level.2, the float-type that contains magnetic material: magnet is embedded in float inside,, can makes corresponding magnetosensitive switch motion, detect corresponding water level in view of the above when float moves to ad-hoc location with the water surface.3, pressure type: adopt pressure cell to detect owing to pressure differential that water surface fluctuation produced realizes measurement to water level.The used utensil of these detection methods all can deposit and influence detection performance because of scaling and impurity.Caused the fault rate height, service life is short.Though the real core water-level and water-temperature test bar (ZL96248024.X) of antiscale has adopted the measure of anti-incrustation scale, because in use test bar soaks in water all the time, its average life is only about 2 years.
Summary of the invention
The purpose of this utility model provides a kind of water level and temperature detector of solar water heater, and it in use can not be subjected to the influence of scaling and water temperature and quality, thereby reduces fault rate, increases the service life.This checkout gear can directly be installed and used by the spout hole or the steam vent of header tank, and needn't change the original structure of casing.Can cooperate the measurement of different change-over circuit realizations to water-level and water-temperature.
The technical scheme that its technical problem that solves the utility model adopts is: the two ends of outer tube are respectively equipped with pedestal and boxcar, and its end that is provided with pedestal can insert in the water tank by the overflow pipe of water-heater water tank.Be equipped with fork on the pedestal, an end of fork connects float, and the other end connects a backguy.Backguy is passed in the outer tube with the swing component that is provided with in the boxcar and is connected.The process of water level detecting is as follows: float and fork rise or descend along with water level and move, and pass to swing component by backguy simultaneously and make it produce corresponding moving.Cooperate the different switching circuit can realize measurement according to the displacement of swing component to water level in the water tank.Temperature element is encapsulated in the flexible pipe, and flexible pipe penetrates and hangs down in the outer tube measures water temperature in the water tank.Owing to have only float to contact with water with the thermometric flexible pipe in the water tank, boxcar is in the water tank outside, so water and water level and temperature detector do not have electrical relation in testing process.Therefore, incrustation scale and water temperature and water quality all can not influence the detection performance of utensil.
The beneficial effects of the utility model are: in use can not be subjected to the influence of scaling and water temperature and quality, prolong service life, reduce fault rate.Can not change solar water heater's original state, install by spout hole.Have simple in structure, stable performance, characteristics easy for installation.
Description of drawings
Figure is a kind of structural representation of water level and temperature detector of solar water heater
1, float 2, fork 3, axle A 4, pedestal 5, backguy 6, contains the flexible pipe of temperature element
7, swing component 8, spring 9, axle B 10, binding post 11, boxcar 12, outer tube
21, header tank 22, heat-insulation layer 23, overflow pipe.
The specific embodiment
Known that by figure an end of outer tube 12 is equipped with pedestal 4, the other end is fixed on the boxcar 11.Be provided with a B9 in the boxcar 11.Swing component 7 is installed in a B9 and goes up and can swing.Spring 8 is fixed in the boxcar 11, and the one end connects swing component 7.Pedestal 4 is provided with an A3, and fork 2 can be swung on axle A3.Fork 2 one ends are equipped with float 1, pass outer tube 12 by backguy 5 other end of fork 2 is associated in swing component 7.Be provided with binding post 10 in the boxcar 11.It is sagging in header tank 21 that the flexible pipe 6 that contains temperature element passes outer tube 12, and the lead of its temperature element is connected with binding post 10.
The course of work is as follows: when anhydrous or water level descended in the header tank 21, fork 2 and float 1 were because the effect of self gravitation can be that the center of circle is to lower swing with axle A3.Drive the active force that swing component 7 overcomes spring 8 by wiring 5 simultaneously, make swing component 7 do corresponding swing.When the active force of the self gravitation of fork 2 and float 1 and spring 8 and buoyancy reach balance, stop to lower swing.When water level rose in the header tank, float 1 was subjected to buoyancy upwards, can break above-mentioned balance, along with the rising of water level, and fork 2 and upwards swing of float 1.Simultaneously, because the effect swing component 7 meeting corresponding mobile of spring 8 reach new balance, swing stops.
The result of the above-mentioned course of work is: along with the variation of water level, swing component 7 produces corresponding displacement, cooperates different change-over circuits, realizes the measurement to water level.
Know that by figure header tank 21 is provided with heat-insulation layer 22 and overflow pipe 23.The present invention can directly insert from overflow pipe 23 and use, and needn't change the original structure of header tank 21.If change the position of backguy 5 on fork 2, the present invention can vertical direction install and use.
