Abstract
A water level sensor installed on the bottom portion of a water storage tank comprises a floater rod and a floater, the floater is located at one end of the floater rod, and a rotation shaft is arranged at the other end of the floater rod. The water level sensor is characterized in that the rotation shaft is installed on the bottom portion of the water storage tank. The rotation shaft of the floater rod is installed on the bottom portion of the water storage tank, the floater rod is in a horizontal state in a non-water state, the floater has a maximum force arm when water is fed, and the defect in the prior art that swing of the floater rod is apt to be out of order. The water level sensor has the advantage of good stability.
Description
Technical field
The utility model relates to the structure of solar water heater, specifically is meant a kind of level sensor that is installed on the reserve tank bottom.
Background technology
The solar water heater storage water tank automatic water-supply apparatus need be measured the water level in the reserve tank in order to control water, a kind of level sensing device commonly used, and it comprises ball lever; End at ball lever is provided with ball float, and the other end of ball lever is provided with variable-resistance moving contact, utilizes different water levels; The different angles of ball lever swing, the respective change of resistance value is measured water level, and prior art is arranged on this level sensor at the top of reserve tank; When reserve tank was anhydrous, ball lever is under the effect of gravity, and was sagging naturally; The arm of force that buoyancy produced of ball float is very little during last water, and it is malfunctioning that the ball lever swing takes place in the use easily, exists poor stability and get defective.
Summary of the invention
The purpose of the utility model is to above-mentioned defective, proposes a kind of level sensor that is installed on the reserve tank bottom of good stability.
The purpose of the utility model is achieved in that a kind of level sensor that is installed on the reserve tank bottom of the utility model; It comprises ball lever and ball float; Ball float is at an end of ball lever, and the other end of ball lever has rotating shaft, it is characterized in that above-mentioned rotating shaft is installed in the bottom of reserve tank.
The level sensor that is installed on the reserve tank bottom of the utility model; Owing to the bottom that the rotating shaft of ball lever is installed in reserve tank, during anhydrous state, ball lever is the level of state; Ball float has the maximum arm of force during last water, has overcome prior art ball lever swing malfunctioning defective easily.The utlity model has the characteristics of good stability.
Description of drawings
Fig. 1 is the structural representation of the level sensor that is installed on the reserve tank bottom of the utility model.
