Abstract
The utility model relates to a liquid level sensor of a solar water heating system, which comprises a pipeline connector, a water inlet pipe, an air-liquid separator, an air outlet opening and a pressure sensor, wherein one end of the water inlet pipe is connected with a pipeline at the bottom of a water tank of the solar water heating system through the pipeline connector, the other end of the water inlet pipe is placed at the bottom of the air-liquid separator, the top of the air-liquid separator is provided with the air outlet opening, and an air inlet opening of the pressure sensor is connected on the air outlet opening through an air transmission pipe. The utility model has a work mode that the water inlet pipe transmits the pressure of water in a hot water storage tank into the air-liquid separator, the pressure is transmitted to the pressure sensor through air of the air-liquid separator, the pressure is converted into the liquid level through the pressure sensor and peripheral circuits thereof, the precision is high, and the temperature drift is small.
Description
Technical field
The utility model relates to the solar water heating system technical field, specifically is a kind of solar water heating system liquid level sensor.
Background technology
The solar water heating system liquid level sensor of generally selling mostly is segmentation liquid level sensor or the electric pole type level sensor that tongue tube is made greatly in the market, be divided into 4 sections demonstrations, display precision is low, transportation is inconvenient, is difficult to satisfy the requirement of high precision in control.
The pressure type liquid level sensor of selling on the market exists temperature to float seriously mostly, and gas-liquid can't be isolated, flimsy shortcoming after the fouling.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of solar water heating system liquid level sensor, it separates water tank water with pressure sensor, realize real gas-liquid separation, guarantees the service life and the high-precision requirement of pressure sensor.
For addressing the above problem, the utility model by the following technical solutions: a kind of solar water heating system liquid level sensor comprises pipe jointer, water inlet pipe, gas-liquid separator, gas outlet, pressure sensor; Described water inlet pipe one end is connected with the water tank bottom pipeline of solar water heating system by pipe jointer; The water inlet pipe other end places the gas-liquid separator bottom; The top of gas-liquid separator is provided with described gas outlet, is connected with the air inlet of pressure sensor by appendix on the gas outlet.
As further technical scheme of the present utility model:
In this solar water heating system liquid level sensor, described pressure sensor is selected the silicon pressure sensor of built-in temperature drift compensation for use.
The beneficial effects of the utility model are: to be water inlet pipe pass to the pressure of water in the hot water storage tank in the gas-liquid separator its working method, by gas-liquid separator gas pressure is passed to the pressure sensor place, by automatically controlled plate pressure is converted to liquid level, the precision height, temperature is floated little.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the circuit theory diagrams of the utility model embodiment;
Among the figure: 1 pipe jointer, 2 water inlet pipes, 3 gas-liquid separators, 4 gas outlets, 5 pressure sensors, 6 appendixs.
The specific embodiment
As shown in Figure 1, this solar water heating system liquid level sensor comprises pipe jointer 1, water inlet pipe 2, gas-liquid separator 3, gas outlet 4, pressure sensor 5.Described water inlet pipe 2 one ends are connected with the water tank bottom pipeline of solar water heating system by pipe jointer 1; Water inlet pipe 2 other ends place gas-liquid separator 3 bottoms; The top of gas-liquid separator 3 is provided with described gas outlet 4, is connected with the air inlet of pressure sensor 5 by appendix 6 on the gas outlet 4.In this solar water heating system liquid level sensor, described pressure sensor is selected the silicon pressure sensor of built-in temperature drift compensation for use.Appendix 6 can adopt medical silicone tube.
Be illustrated in figure 2 as the circuit theory diagrams of this solar water heating system liquid level sensor, comprise pressure sensor U1, mu balanced circuit element U2, electric capacity and resistance R 1.Capacitor C 1, C2 play filter action, and resistance R 1 is used for dividing potential drop.
All the other do not state technology is prior art.
