Problems solved by technology

[0003] During the working process of the regulating valve, due to the distance of the pressure, the valve core and the valve stem may deviate from the axis, resulting in wear and tear, which affects the sealing and service life of the valve body. Therefore, we have designed a high-pressure resistant regulating valve to solve the problem. above questions

Abstract

The invention discloses a high-pressure-resistant regulating valve. The high-pressure-resistant regulating valve comprises a valve body. A valve body inlet and a valve body outlet are formed in the two sides of the valve body correspondingly. A valve element is arranged at the junction of the valve body inlet and the valve body outlet. A valve seat matched with the valve element is arranged on the valve body. A mounting base is fixed to the valve body, and a first sealing plate and a second sealing plate are connected to the inner side of the mounting base through springs. Limiting plates are arranged at the two ends of the first sealing plate correspondingly. A sliding clamp block is arranged at the end, away from the first sealing plate, of each limiting plate. A valve deck is arranged on the upper side of the valve body. A valve rod is perpendicularly arranged at the center of the side, close to the valve deck, of the valve element. Two guide rods which are perpendicularly mounted on the valve element are arranged on the outer side of the valve rod. Two supporting plates in symmetrical positions are arranged on the inner wall of the valve body. Guide through holes which are matched with the guide rods are formed in the supporting plate. The high-pressure-resistant regulating valve is simple in structure and good in airtightness, abrasion of the regulating valve is effectively reduced, and the service life of the valve is prolonged.

Description

technical field [0001] The invention relates to the field of regulating valves, in particular to a high pressure resistant regulating valve. Background technique [0002] The valve is the most basic component of automatic control in the entire industrial fluid power pipeline system, which realizes the control of the pressure, flow rate and flow rate of the fluid, and ensures the safety, real-time and effective control of the system. higher requirements. The regulating valve, also known as the control valve, changes the fluid flow by means of power operation by receiving the control signal output by the regulating control unit. A regulating valve generally consists of an actuator and a valve. According to the power used by its matching actuator, the control valve can be divided into three types: pneumatic control valve, electric control valve and hydraulic control valve. In addition, according to its function and characteristics, linear characteristics, equal percentage cha...
