Safe anti-leakage water valve for supply of urban water resources

Abstract

The invention belongs to the technical field of valves, in particular to a safe anti-leakage water valve for supply of urban water resources. The safe anti-leakage water valve comprises a valve body,a valve rod module, a sealing module, an annular air sac, auxiliary sealing modules and a rotating module, wherein the valve rod module and the sealing module are mounted in a vertical cavity of the valve body; the valve rod module is arranged on the inner side of the sealing module; the annular air sac is fixedly connected to the top of the sealing module on the inner wall of the vertical cavityof the valve body; the rotating module is mounted at the bottom of the vertical cavity of the valve body; the auxiliary sealing modules are mounted in a horizontal cavity of the valve body; the sealing module comprises a sealing block, an elastic sealing cushion and a No.1 cavity; elastic sealing cushions are respectively and fixedly connected with two sides of the bottom of the sealing block; thevalve rod module comprises a screw rod; and the bottom end of the screw rod penetrates through the No.1 cavity to extend to the bottom of the vertical cavity. Through the adoption of the safe anti-leakage water valve disclosed by the invention, the service life of the elastic sealing cushions can be prolonged; and the annular air sac and the auxiliary sealing modules cooperate with the elastic sealing cushions for usage, so that the valve body is subjected to multistage sealing, and the sealing efficiency of the valve body is improved.

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to a safe and anti-leakage water valve used for supplying urban water resources. Background technique [0002] With the continuous development of the city, the urban water supply system is becoming more and more important, and the planning of the urban water supply system is an integral part of the overall urban planning. Urban water supply systems usually consist of water sources, water pipelines, water plants and water distribution networks. After water is taken from the water source, it is sent to the water plant through the water delivery pipe for water treatment. The treated water is pressurized and sent to the user through the water distribution network. During the tap water delivery process, valves are required to prevent tap water from leaking. However, after the valve is used for a long time, there is a phenomenon that the sealing material is damaged and consumed due to fri...

Problems solved by technology

However, this type of water valve is closed only with a gasket when used. After a long period of use, the gasket will be worn and the sealing effect of the gasket will be reduced, resulting in leakage and reducing the service life of the water valve. Therefore, it is proposed A safe and anti-leakage water valve for urban water supply, capable of multi-stage sealing of the water valve to prevent leakage of the water valve, effectively improving the sealing efficiency of the water valve and prolonging the service life of the water valve
