Abstract

The invention relates to a rotary multi-way valve with pressure maintaining and shock preventing functions, and belongs to the technical field of fluid reversing valves. The technical problems that for an existing valve, a pressure maintaining function can not be achieved, operation is tedious, and misoperation is liable to be caused are solved. According to the technical scheme, the rotary multi-way valve with the pressure maintaining and shock preventing functions comprises a valve body, a valve element, a front end cover, a back end cover and a safety valve assembly and further comprises a valve element positioning sheet, a reset spring, a fastening screw and a spring base; a valve element hole is formed in the center of the valve body, a P-cavity annular groove is formed in the middle of the valve element hole, a T-cavity annular groove is formed in the end, close to the back end cover, of the valve element hole, the P-cavity annular groove communicates with an oil inlet, and the T-cavity annular groove communicates with an oil return inlet; the valve element is arranged in the valve element hole and can rotate around the axis of the valve element and axially move; two groups of inclined fluid working channels and two groups of parallel vertical fluid working channels are formed in the axial cross section of the valve body.

Description

technical field [0001] The invention belongs to the technical field of fluid reversing valves, in particular to a rotary multi-way valve with pressure maintaining and anti-shock. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. There are many kinds of valves in the existing market, but most of the existing valves have a one-valve-one-channel structure, and their application conditions are relatively simple; on agricultural machinery, most of the existing multi-way reversing valves are multi-handle-operated and the working oil circuit Without the pressure holding function, there are disadvantages such as cumbersome operation and easy misoperation during use. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior a...
