Buried antifreezing anti-siphon quick water take valve

Abstract

The invention relates to a buried antifreezing anti-siphon quick water take valve, in particular to the technical field of water take valves. The buried antifreezing anti-siphon quick water take valveis simple in structure and is composed of a water tank handle and a water take valve body. A water valve is mounted in the water tank valve body; the water tank handle and the water tank valve body are through with a water flow by means of simple rotary splicing; the valve body is buried underground; when the water tank handle is pulled out, residual water in the water take valve body will be discharged automatically, the inner valve of the water tank valve body separates tap water to an un-frozen part, and the water tank valve body can be made in different lengths according to anti-freezingdemands to make sure that a pipeline is not frozen or frosted in cold winter, so that the buried antifreezing anti-siphon quick water take valve is conveniently used by a user, and the water resourceis saved. Meanwhile, a one-way valve is also arranged on the water tank valve body. Once a water supply pipeline losses pressure, the one-way valve is opened automatically, and air enters the valve body cavity, so that the siphonic effect is avoided, and sewage is prevented from being sucked back to the water supply pipeline.

Description

technical field [0001] The invention relates to the technical field of water intake valves, in particular to a buried antifreeze and anti-siphon fast water intake valve. Background technique [0002] As the earth's environment is increasingly destroyed and environmental pollution is becoming more and more serious, the temperature in summer is getting higher and higher, and the temperature in winter is getting lower and lower. In most parts of northern my country, the temperature in winter is usually tens of degrees below zero. Once exposed to the air, it will freeze immediately. The water in the outdoor faucet often freezes due to the low temperature, causing the faucet to fail to work or even the pipeline to be frozen. People usually use the method of covering the faucet with insulation measures to prevent freezing. [0003] Due to the special structure of the faucet and the simple covering method, its thermal insulation effect is not ideal. Moreover, covering the thermal in...
