Abstract

The utility model discloses a water-temperature water-level sensor which comprises operation lines, stainless steel sleeves, and silicone tubes; the stainless steel sleeves and the silicone tubes are arranged at intervals and are connected with each other, the operation lines are arranged in the stainless steel sleeves and the silicone tubes, each conductor of the operation lines is respectively fixed and connected with the inner wall of each stainless steel sleeve, the stainless steel sleeves and the silicone tubes are full of fluid silica gel inside, the operation lines are sealed and covered by the fluid silica gel. As the silicone tube is softer, the heat-resistant property of the silicone tube is better, and the silicone tube causes the whole sensor to be sealed integrally, so the operation stability of the sensor can be effectively ensured, and the service life of the sensor can be prolonged.

Description

A water temperature and water level sensor

technical field

The utility model relates to a water temperature and water level sensor, in particular to a water temperature and water level sensor for a solar water heater.

Background technique

The water temperature and water level sensor of the solar water heater is arranged in the water tank to detect the water temperature and water level in the water tank. The structure of the sensor generally includes working lines, stainless steel sleeves and heat shrinkable tubes (generally made of rubber materials). The tubes are distributed at intervals and connected airtightly to seal the working circuit. Since the sensor has been soaked in the water tank for a long time, affected by the high temperature and temperature changes of the water tank, the heat shrinkable tube itself and the connection between the stainless steel sleeve are prone to cracks or breaks, which makes the working line soaked in water and cannot work normally. Affect the working stability and service life of the sensor.

Contents of the invention

The technical problem to be solved by the utility model is to propose a water temperature and water level sensor with good working stability and long service life.

In order to solve the above technical problems, a water temperature and water level sensor of the utility model includes a working circuit, a stainless steel sleeve and a silicone tube, the stainless steel sleeve and the silicone tube are spaced apart and connected to each other, and the working circuit is set on the stainless steel tube. In the sleeve and the silicone tube, the wires of the working circuit are fixedly connected to the inner walls of the stainless steel sleeves, and the stainless steel sleeve and the silicone tube are filled with fluid silicone, and the fluid silicone will The working line is enclosed and covered.

In the above-mentioned water temperature and water level sensor, a step is provided on the inner wall of the port of the stainless steel sleeve, and the silicone tube is sleeved on the step.

Due to the adoption of the above-mentioned technical structure in the utility model, when making it, the wires of the working circuit are fixedly connected with the inner walls of the stainless steel sleeves respectively, the stainless steel sleeves and the silicone tubes are spaced apart and connected to each other, and then the fluid silicone is injected The inside of the stainless steel casing and the silicone tube, so that the working circuit is sealed and covered after the silicone is hardened, and the junction of the stainless steel sleeve and the silicone tube is also sealed. Since the silicone tube is relatively soft, its high temperature resistance is better, and it seals the entire sensor in one piece, so it can effectively ensure the working stability of the sensor and prolong the service life of the sensor. The silicone tube is set on the step set on the inner wall of the stainless steel sleeve port, which can prevent the silicone tube from coming out of the stainless steel sleeve when the fluid silicone is injected.

Description of drawings

Fig. 1 is a structural schematic diagram of the water temperature and water level sensor of the present invention.

Detailed ways

As shown in Figure 1, the water temperature and water level sensor includes a working circuit 1, a stainless steel sleeve 2 and a silicone tube 3, the stainless steel sleeve 2 and the silicone tube 3 are distributed at intervals, the inner wall of the port of the stainless steel sleeve 2 is provided with steps, and the silicone tube 3 is set. on that step. The working circuit 1 is arranged in the stainless steel casing 2 and the silicone tube 3 , and the wires of the working circuit 1 are respectively fixedly connected with the inner walls of the stainless steel casing 2 . The inside of the stainless steel casing 2 and the silicone tube 3 is filled with fluid silicone 4 , and after the fluid silicone 4 dries hard, the working circuit 1 is sealed and covered, and is connected with the silicone tube 3 into one body. At the same time, through penetration, the fluid silica gel 4 also seals the junction between the silica gel tube 3 and the stainless steel casing 2 .
