Embodiment Construction

[0016] like figure 1 As shown, the anti-freezing and cracking solar water heater inlet and outlet pipes include solar water heater inlet and outlet pipes 5, inflation device 1, gas cylinder 4, pressure measuring devices 6, 7 and display device 9. The inlet and outlet water pipes 5 of the solar water heater are connected to the water storage tank 8 .

[0017] The gas cylinder 4 air inlet is connected with the inflation device 1 through a pipeline. The air outlet of the cylinder is connected with the solar water heater water inlet pipe 5. A pressure limiting valve 2 is installed between the gas cylinder 4 and the inflation device 1 . A control valve is installed between the gas cylinder and the solar water heater water inlet pipe 5.

[0018] The inflator can be an air pump or an electric inflator. The pump is manually operated and consumes no energy.

[0019] A pressure measuring device 6 is installed on the cylinder. The top of the water inlet and outlet pipe 5 is equippe...

Abstract

The invention discloses a frost crack prevention solar water heater water inlet-outlet pipe which comprises a water inlet-outlet pipe body connected with a water storage tank of a solar water heater, an inflation device, an air cylinder, pressure measurement devices and a display window. An air inlet of the air cylinder is connected with the inflation device through a pipeline, an air outlet of the air cylinder is connected with the water inlet-outlet pipe body of the solar water heater, a pressure limit valve is arranged between the air cylinder and the inflation device, and a control valve is arranged between the air cylinder and the water inlet-outlet pipe body of the solar water heater. One pressure measurement device is arranged on the air cylinder. The other pressure measurement device is arranged at the top end of the water inlet-outlet pipe body, the display device is arranged in a user house, the pressure measurement device at the top end of the water inlet-outlet pipe body is connected with the display device through a guide wire, and when the pressure value on the display device in the user house is equal to the pressure value of the pressure measurement device on the air cylinder, the water inlet-outlet pipe body is filled with air. The frost crack prevention solar water heater water inlet-outlet pipe is ingenious in concept and simple in structure, saves energy, is environmentally friendly and low in production cost, solves the problem that frost crack easily occurs to the solar water heater water inlet (outlet) pipe, and eradicates water waste.

Description

technical field [0001] The invention relates to an inlet and outlet pipe of an anti-freezing and cracking solar water heater, which belongs to the technical field of solar heating equipment. Background technique [0002] Solar water heaters are favored by consumers because of their energy saving, high heating efficiency and low cost. However, in the actual use of solar water heaters, there are the following problems: first, after the water heater is filled with water, the water inlet pipe of the water heater is still full of tap water. Frozen or frozen phenomenon, resulting in cracking or blockage of pipes; Second, the water in the inlet pipe of the solar water heater has not been heated, so its temperature is room temperature. When the user uses hot water in the solar water heater, the cold water in the inlet pipe needs to be first Drainage, most users drain it directly, the amount of cold water drained at one time is not large, but the amount of water wasted is considerab...
