Bidirectional water leakage-proof valve

Abstract

The invention relates to a bidirectional water leakage-proof valve. The bidirectional water leakage-proof valve comprises a valve body, wherein the valve body comprises two parts, namely a water supply side cavity and a backwater side cavity; a water supply side water inlet connected with a municipal water supply pipe is formed in one end of the water supply side cavity, and a water supply side water outlet connected with a home inner heating pipeline is formed in the other end of the water supply side cavity; a regulating valve used for regulating flow of the water supply side cavity is arranged at one end, close to the water supply side water inlet, inside the water supply side cavity, and a water sealing plate controlled to be opened and closed by flow pressure is arranged at one end, close to the water supply side water outlet, inside the water supply side cavity; a backwater side water outlet connected with a municipal backwater pipe is formed in one end of the backwater side cavity, and a backwater side water inlet connected with the home inner heating pipeline is formed in the other end of the backwater side cavity; and a water sealing valve and a check valve only allowing circulation from the backwater side water inlet to the backwater side water outlet are arranged inside the backwater side cavity. The bidirectional water leakage-proof valve provided by the invention effectively avoids large-area water leakage.

Description

technical field [0001] The invention relates to the technical field of anti-leakage devices for pipelines, in particular to a two-way anti-leakage water valve. Background technique [0002] At present, residential central heating systems often leak a lot of water due to damage to household heating pipes or equipment. Due to the high heating pressure, it will cause floods to families and even affect neighbors in a few minutes. At present, the anti-leakage technology adopted in the market is infrared remote sensing to control electronic valves, which is complicated, expensive, and sometimes misjudged; at the same time, some residents’ homes are not heated, so they put hot water into the sewer to increase the flow rate to For the effect of increasing heat, the heating company has to continuously add water to heat up, which also causes a lot of waste of water resources and heat. It is also a headache for the heating company at present, and there is currently no effective solutio...

[0002] At present, the residential central heating system often leaks a lot of water due to damage to the heating pipes or equipment in the home. Due to the high heating pressure, it will cause floods to the family in a few minutes, and even affect the neighbors.

At present, the anti-leakage technology adopted in the market is infrared remote sensing to control electronic valves, which is complicated, expensive, and sometimes misjudged; at the same time, some residents’ homes are not heated, so they put hot water into the sewer to increase the flow rate to To increase the heat effect, the heating company has to continuously add water to heat up, which also causes a lot of waste of water resources and heat. It is also a headache for the heating company at present, and there is no effective solution at present
