Torque calculation of forged steel ball valve…

The three-piece forged steel ball valve divides the valve body into three parts along a cross-section perpendicular to the axis of the valve passage with two valve seats, and the whole valve is symmetrical along the central axis of the valve stem. The three-piece forged steel ball valve is used for pipeline interruption. and distribution.…

The flat gate valve has two floating valve seats. Each seat is designed to be sealed when the medium flows in both directions. Therefore, the flat gate valve can not only achieve two-way sealing, but also realize the simultaneous sealing of the inlet and outlet.…

Expansion type double gate plate gate valve is suitable for chemical, petroleum, natural gas, power plant, coal mine, construction, steel, light industry and sewage treatment industries. Because there are often hard particles and fibrous dirt and other objects in the medium, the valve can play an excellent role as an opening and closing device in the pipeline system. Its driving methods include ma…

a parallel single-gate gate valve without diversion holes. The valve adopts the valve seat to float downstream, the spring preloads the automatic sealing structure, the opening and closing force is small, the higher the working pressure, the better the sealing performance. The seal is provided with a sealing grease injection mechanism. Mainly made of carbon steel, stainless acid-resistant steel, a…

Axial-flow check valve should have a streamline shape on the surface of the inner cavity of the valve body, the diversion cover, the valve flap and other flow surfaces, with a rounded front and a sharp back. The fluid is mainly on its surface as layer flow, and there is no or rarely turbulence.…

Explosion-proof electric regulating valve is an important execution unit instrument in industrial automation process control. With the increasing degree of automation in the industrial field, it is being used more and more in various industrial production fields. The valve is divided into three types: linear characteristic, equal percentage characteristic and parabolic characteristic according to …

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. The regulating valve generally consists of an actuator and a valve. According to the power used by the actuator, the control valve can be divided into three types: pneumatic control valve, electric control valve and hydraul…
