Explosion-proof, anti-vacuum self-relieving safety valve

Abstract

The invention relates to a blast and vacuum prevention self-detaching safety valve for solar energy water heater, which belongs to the technical field of solar energy water heater. The invention comprises two column shaped pipelines, a round drum shaped pipeline positioned between a round pipeline at two ends and communicated with two round pipelines, as well as a spherical ball with less specific gravity than water being positioned inside the round drum shaped pipeline and can move inside the pipeline. Wherein, an upper end port in the round column shaped pipeline is configured as the overflow port or air inlet port or air outlet port for the safety valve; a lower end port in the round column shaped pipeline is configured as the water outlet port or air inlet port or air outlet port for the safety valve; a plurality of bordering gaps are made on the internal wall at the interface of the round column shaped pipeline connected with the round drum. Therefore, the invention, which can be applied to ensure the safe application of solar energy water heater, has the advantages of simple structure, low cost and easy realization.

Description

technical field [0001] The invention belongs to the field of solar water heaters, in particular to the design of an explosion-proof and vacuum-proof self-release valve for solar water heaters. Background technique [0002] Today's energy-saving and environmentally-friendly solar water heaters are attracting more and more attention, but in actual use, the water storage container of the solar water heater often explodes when the water pressure is too high, or the water cannot be replenished in time when hot water is used, resulting in a vacuum that makes the inner barrel (container) ) was pumped flat and other security issues. Water supply tanks have been used to solve the vacuum problem, but the water supply tank itself also has problems such as anti-vacuum, anti-freezing, heat dissipation, and cumbersome appearance. Explosion problems have been used by explosion-proof valves. Although the explosion-proof has been solved, problems such as vacuum protection, anti-freezing, an...

Problems solved by technology

[0002] Today's energy-saving and environmentally-friendly solar water heaters are attracting more and more attention, but in actual use, the water storage container of the solar water heater often explodes when the water pressure is too high, or the water cannot be replenished in time when hot water is used, resulting in a vacuum that makes the inner barrel (container) ) is deflated and other security issues

Water supply tanks have been used to solve the vacuum problem, but the water supply tank itself also has problems such as anti-vacuum, anti-freezing, heat dissipation, and cumbersome appearance.

Explosion problems have been solved by using explosion-proof valves. Although the explosion-proof has been solved, the problems of vacuum protection, anti-freezing, and heat dissipation cannot be solved.

These problems have hindered the further popularization and use of solar water heaters
