Embodiment Construction

[0009] An insulated solar water heater, comprising a water tank 3 and a heat collecting pipe 6, an air inlet pipe 4 and an exhaust pipe 2 are arranged on the upper part of the water tank 3, an air inlet valve 5 is installed on the air inlet pipe 4, and an exhaust pipe 2 is installed on the air inlet pipe 2. valve 1. The air intake pipe 4 is arranged on the side of the water tank 3, and the mouth of the pipe is arranged downwards. The air intake valve 5 includes a valve chamber located at the lower end of the mouth of the air inlet pipe, and an air intake float is arranged near the air inlet end of the valve chamber. ball. The exhaust pipe 2 is arranged on the top or side of the water tank 3, and the mouth of the pipe is set upwards. The exhaust valve 1 includes a valve cavity located at the upper end of the mouth of the exhaust pipe 2, and is provided near the exhaust end of the valve cavity. A vent float.

Abstract

The invention relates to a heat-insulation solar water heater comprising a water tank and a heat collection pipe, wherein the upper part of the water tank is provided with an air inlet pipe and an air exhaust pipe, the air inlet pipe is provided with an air inlet valve, and the air exhaust pipe is provided with an air exhaust valve. Because the water tank is provided with the floating ball type air inlet valve and the floating ball type air exhaust valve, when sunlight is sufficient in the daytime, the temperature of water inside the water tank is increased, the inner pressure of the water tank is enhanced so that floating balls of the air exhaust valve can be propped up to exhaust air so as to reduce the inner air pressure of the water tank, or when water enters the water tank, the inner pressure of the water tank can also be enhanced, and the air exhaust valve can also plays roles of exhausting the air and reducing the pressure; when the air temperature is reduced or light is insufficient in nights, the floating balls are lowered to cover on a valve opening so that heat air can not be diffused so as to play a role of heat insulation; when the water is used, the inner pressure of the water tank is reduced, and the air inlet valve is opened at the same time to supplement air for the water tank and regulate the inner air pressure of the water tank so that the inner and outer pressure of the water tank is kept balanced.

Description

technical field [0001] The invention relates to a solar energy utilization device, in particular to a thermal insulation solar water heater. Background technique [0002] The solar water heater of the prior art includes a water tank and a heat collecting pipe, and the water tank is provided with an exhaust port, some of which are located on the top of the water tank, and some are on the side of the water tank, in order to adjust the internal and external air pressure of the water tank. Its weak point is: when regulating air pressure, a large amount of heat also dissipates in vain, has reduced the thermal insulation performance of solar water heater. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a thermal insulation solar water heater with good thermal insulation performance in view of the deficiencies of the prior art. [0004] The technical problem to be solved by the present invention is achieved through the...
