Valve body structure of pneumatic regulating ball valve


Release time:

2022-12-17

Wuxi Xinming automatic control valve industry Co., Ltd. tells you the valve body structure of pneumatic regulating valve Pneumatic control valve Pneumatic control ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipelines. Its strength, safety, and resistance to harsh environments have been specially considered in the design. It is suitable for various corrosive and non-corrosive media. Compared with the floating ball valve, the fixed electric ball valve has the force generated by the fluid pressure on the ball before the electric control valve is transmitted to the bearing, and the ball will not move to the valve seat, so the valve seat will not bear excessive pressure. Therefore, the fixed ball valve has small torque, small deformation of the valve seat, stable sealing performance and long service life, and is suitable for high pressure and large diameter occasions. Advanced spring pre-seat assembly with self-tightening characteristics to achieve upstream sealing. Steam control valve each valve has two seats, each direction can be sealed, so the installation is not flow restriction, is two-way.

Pneumatic regulating ball valve has two-block and three-block valve body structure. The middle flange is connected by bolts. The seal is embedded in the stainless steel ring with reinforced polytetrafluoroethylene. There is no spring at the rear of the steel ring to ensure that the valve seat is close to the ball and keeps the seal. There are no PTFE bearings on the upper and lower valve stems, which reduces friction and saves labor. There is no adjusting plate at the bottom of the small shaft of the self-operated regulating valve to ensure the joint position between the ball and the sealing ring.
