Problems solved by technology

[0002] Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valve to extremely complex The various valves used in the automatic control system have a wide variety of varieties and specifications. The valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. , The diameter of the water inlet and outlet of the existing valve is the same. After being washed by the fluid for a long time, the surface is easy to scale, which affects the flow speed, thereby increasing the pressure bearing pressure of the valve. After a long time, it will cause impact on the valve and reduce the valve's performance. Service life, for this reason, we propose a processing technology for erosion-resistant valves

Abstract

The invention relates to the technical field of valves, in particular to a washing-resistant valve.The washing-resistant valve comprises a valve body, wherein a liquid inlet is formed in the left sideof the valve body, a liquid outlet communicatingwith the liquid inlet is formed in the right side of the valve body, a valve element is arranged at thesection, located between the liquid outlet and the liquid inlet, of the valve body, the side, close to the liquid inlet, of the valve element is provided with a first through hole communicating with the liquid inlet, a second through hole communicatingwith the liquid outlet is formed in theside, close to the liquid outlet, of the valve element, the second through hole communicates with the first through hole, and the bore diameter of the firstthrough hole is smaller than the bore diameter of the second through hole. By changing the through diameter of the through hole in the middle of the valve element, the flowing pressure of awater inletsection and a water outlet section of the valve element is changed, so that the impact of fluid on the inner wall of the valve element and the inner wall of the valve body is effectively reduced, atthe same time, theend, close to the second through hole, of the liquid outlet is of an arc-shaped structure, so that the impact reflection direction of the fluid is changed, and the effectivebufferingis achieved.
