Abstract

The invention discloses a dovetail groove type soft seal cutting adjustment valve. The adjustment valve comprises a valve body, a valve element and a valve rod; a first medium channel is formed in theleft lower end of the valve body; a second medium channel is formed in the right upper end of the valve body; the valve body is provided with a current limiting separation plate; a first positioninggroove is formed in an outlet of a medium through hole of the current limiting separation plate; a first winding gasket is arranged in the first positioning groove, and is provided with a first valvebase; a valve base through hole is axially formed in the middle part of the first valve base; a valve base convex ring is integrally arranged on the upper end surface of the first valve base; a soft seal valve base mounting groove is formed in the middle part of the upper end surface of the valve base convex ring; a soft seal valve base is embedded in the soft seal valve base mounting groove; thevalve element is mounted in a valve element movable cavity; the upper end of the valve element is detachably connected with the lower end of the valve rod; and a sealing convex block is arranged on the lower end surface of the valve element. The adjustment valve is reasonable in structural design, simple in structure, multiple in function, excellent in sealing performance, low in machining difficulty, high in production efficiency and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a dovetail groove type soft seal cut-off regulating valve. Background technique [0002] Control valve, also known as control valve, in the field of industrial automation process control, is the final control element that changes the process parameters such as medium flow, pressure, temperature, liquid level, etc. by means of power operation by receiving the control signal output by the adjustment control unit. It is generally composed of actuators and valves. Regulating valves play a very important role in the automatic control of modern factories whose production depends on the correct distribution and control of the flowing medium. Whether these controls are energy exchange, pressure reduction or simple container filling, some final control elements are required to complete. [0003] The existing regulating valve has unreasonable structural settings and single function. Gener...
