Description

Technical Field

[0001] The utility model relates to the technical field of water valve sealing components, in particular to a water valve sealing component. Background Art

[0002] Valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems, with functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shut-off valves to various valves used in extremely complex automatic control systems.

[0003] After searching, the Chinese patent application number is: CN202321005305.2, which relates to a water valve seal in the technical field of water valve seals, including a valve outlet pipe, the output end of the valve outlet pipe is sleeved with a connecting pipe, the other end of the connecting pipe and the outer surface of the valve outlet pipe are both provided with a threaded groove, and the valve outlet pipe and the connecting pipe are threadedly connected through the threaded groove, and the inner diameter of the water outlet is smaller than the inner diameter of the end of the connecting pipe with the threaded groove. By setting a threaded valve outlet pipe, a connecting pipe, and a sealing block located at the connection between the valve outlet pipe and the connecting pipe, the water pressure can apply force to the sealing block outward when the water valve is discharging water, and the sealing ring on the surface of the sealing block and the groove on the inner wall of the connecting pipe can improve the sealing effect when the sealing block is pushed outward by the water pressure. At the same time, the setting of the groove and the sealing ring can minimize the situation of the sealing ring being worn and pressed to the greatest extent. The setting of this device can improve the sealing of the seal at the water outlet connection of the water valve.

[0004] The above technical solution still has defects. Like the existing water valve seals, after long-term use, the internal sealing ring is prone to loosening and deformation. Especially before and after maintenance, when the seal is disassembled, the sealing ring lacks positioning, and the sealing ring slides and deviates in the pipe fitting, which easily leads to poor sealing at the connection between the water valve and the pipe fitting. Therefore, we need to propose a water valve seal. Utility Model Content
