Description

Integrated solar control valve

technical field

The utility model relates to an integrated solar control valve, which belongs to the auxiliary accessories of solar water heaters.

technology field.

Background technique

Solar water heaters have the advantages of being clean, pollution-free, safe, and have a large amount of hot water. They are becoming more and more popular. However, most of the solar water heaters on the market are non-pressure-bearing structures, and the pressure of hot water is low due to the use of drop-type water intake. It is difficult to adjust the water temperature during use. The reason is that the pressure of cold water is high and the pressure of hot water is low. Existing solar water heaters are installed in combination with many valves and fittings for water supply and hot water regulation. The pipelines in the bathroom are complex and cause many leakages, difficult installation, high cost, and inconvenient use.

Contents of the invention

The purpose of this utility model is to provide an integrated solar control valve designed completely according to the characteristics of the drop-type solar water heater, which can overcome the above-mentioned shortcomings. A regulating switch can be used for secondary temperature adjustment conveniently. The control valve can adjust the water temperature and flow, supplement cold water to the solar water heater, balance the flow and pressure of cold water and hot water, etc., without installing other valves, and its structure is simple and easy to install.

The structure of the integrated solar control valve is that the main water mixing spool 3 is installed in the valve body 2, the main valve handle 1 is installed on the valve body 2, the left and right parts of the valve body 2 are equipped with a regulating valve spool 4, and the left and right regulating valve spools 4 There is a rotary adjustment handle 9 on the upper part, and the left and right ends of the valve body 2 are the water heater interface 6 and the cold water interface 7. Below the main mixing valve core 3, the valve body 2 has a water interface 8, and the check valve core 5 is respectively installed in the cold water Interface 7 and hot water interface 6 inside.

The advantage of the integrated solar control valve is that two adjustment switches are added to the inlet of hot and cold water, which can easily perform secondary temperature adjustment. One valve body is equipped with two adjustment valve spools and one check valve spool. , a water mixing spool for solar water heaters is a regulating spool, which can first adjust the flow of cold and hot water according to the pressure difference between cold and hot water, and then use the main mixing spool to adjust the temperature. Second, the temperature adjustment becomes simple. There is no need to install a check valve in addition, which avoids the disadvantage that the cold water pipe is concealed and cannot be installed with a check valve.

Description of drawings

Figure 1. Sectional structure diagram of integrated solar control valve

As shown in Figure 1, the main mixing valve core 3 is installed in the valve body 2, the main valve handle 1 is installed on the valve body 2, the left and right parts of the valve body 2 are equipped with the regulating valve spool 4, and the upper part of the left and right regulating valve spool 4 has a rotating The adjustment handle 9, the left and right ends of the valve body 2 are the water heater interface 6 and the cold water interface 7. Below the main mixing valve core 3, the valve body 2 has a water interface 8, and the check valve core 5 is installed on the cold water interface 7 and the hot water interface respectively. Inside the water connection 6 .

Implementation

When in use, cold water and hot water enter the valve body 2 through the cold water interface 7 and the water heater interface 6 respectively. At this time, according to the difference in the pressure of the cold water and hot water, the adjusting handle 9 can be rotated to adjust the flow of the incoming water, so that the intake of cold water and hot water can be adjusted. The water volume is kept roughly equal, and then the water temperature can be adjusted conveniently by adjusting the main valve handle 1. The water interface can be adjusted to warm water, completely cold water or completely hot water. Interconnected, realizing the function of filling water for the solar water heater water tank. The effect of the check valve spool 5 is when the solar water heater is filled with water, as the cold water pressure is less than the hot water pressure or when there is no cold water, the water in the solar water heater water tank will not flow back into the cold water pipeline through the cold water interface 7.
