Abstract

The invention discloses a plunger valve with a good plug protecting effect. The plunger valve comprises flange connecting discs, sealing pads, filtering brackets, a valve shell, sliding pipes, threaded connecting blocks, a sealing circle, a screw, rotating discs, balls, sealing rings, inlet and outlet holes, hooks, connecting pieces, a plug, a buffering pipe, a buffering block, a spring, metal pieces, and reset springs. A cavity body is formed in an inner cavity of the plug. The reset springs are fixedly connected into the inner cavity of the plug, and the metal pieces are fixedly connected tothe ends of the reset springs. The metal pieces are erected on the lateral surfaces of the inner cavity of the plug. Compared with a plug with a conventional fixing structure, the elastic deformationrange of the edge is wider, and abrasion of the plug is reduced. In the case of abrasion of the edge of the plug after longtime use, compensation sealing is conducted by the reset springs to the edgeof the plug, so that sealing effect damage to the edge of the plug and caused by longtime use is avoided.

Description

technical field [0001] The invention relates to a plunger valve, in particular to a plunger valve with good protection effect on the plunger, and belongs to the technical field of valve application. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves and regulating valves. Valves are important components in the fluid conveying system. The control unit has the functions of cut-off, adjustment, flow diversion, reverse flow prevention, voltage stabilization, flow diversion, overflow and pressure relief, etc. [0003] When the existing plunger valve is in use, the sealing effect of the valve is affected due to the wear of the plunger after long-term use, resulting in the valve leaking and being unusable, and the valve is easily blocked by debris when it is used in the se...
