Valve with valve clack convenient to replace and replacing method

Abstract

The invention discloses a valve with a valve clack convenient to replace and a replacing method. The valve comprises a lower valve body, wherein a valve seat is fixedly connected to the center of an inner cavity of the lower valve body, a sealing ring is fixedly connected to the inner wall of the valve seat, an upper valve body is arranged at the top of the lower valve body, fastening screw holesare formed in the two sides of the bottom of the upper valve body and the two sides of the top of the lower valve body correspondingly, fastening bolts are arranged in inner cavities of the fasteningscrew holes in a penetrating mode correspondingly, a valve rod is arranged at the top of the upper valve body, and the bottom of the valve rod sequentially penetrates through the upper valve body andthe lower valve body from bottom to top and extends to the top of the inner cavity of the lower valve body. Through cooperative use of the valve clack, the fastening screw holes, the fastening bolts,the valve rod, the upper valve body, a first screw, a first baffle, a sliding clamping block, a first sliding groove, a limiting clamping block, a stable sliding block, a first spring, a stable sliding groove and a limiting clamping groove which are arranged, the problem that the valve clack of an existing valve is inconvenient to replace, the replacement time is greatly increased, and the convenience of the valve is reduced is solved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a valve and a replacement method for easy replacement of valve clacks. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, 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 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...
