Abstract

A valve body assembly of a high-pressure large-flow fast-response two-position three-way valve belongs to valve body assemblies in a fluid control system. The valve body assembly comprises two inner spool components. The first inner spool component and the second inner spool component are nested into a valve sleeve from left and right ends respectively. The valve sleeve is nested in a valve side shell. Moving parts in the valve body assembly, namely a first inner spool, a second inner spool, and the valve sleeve, are all in fluid pressure-balanced structure, and motion of the moving parts is insusceptible to pressure of controlled fluid. The valve body assembly is applicable to control of high-pressure fluids. During switching, the first inner spool and the second inner spool move in same direction synchronously, the valve sleeve moves reversely and synchronously, response time of a valve body is shortened, total travel of the valve body is increased, and the contradiction between response time shortening and armature travel increasing in traditional valves is overcome. The valve body assembly is applicable to controlling fluids with the requirement for high pressure, large flow and fast response.

Description

technical field [0001] The utility model relates to a valve body assembly of a two-position three-way valve with high pressure and large flow rate and fast response, which belongs to the valve body assembly in a fluid control system. Background technique [0002] Fluid control systems such as hydraulics and pneumatics have been widely used in various sectors of the national economy because of their advantages such as flexible control, large power-to-weight ratio, smooth movement, simple structure, and easy layout. As the main control part of the system, the rapid response capability, flow capacity and high pressure bearing capacity of the valve body assembly are directly related to the further expansion of the application field of the fluid control system. For example, the valve body components used in the fields of vehicle electronic control injection system or variable valve drive system need to meet the response time of milliseconds or lower, the instantaneous flow rate o...
