r, >Fixed 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 during design. It is suitable for various corrosive and Non-corrosive media. Compared with the floating ball valve, when it works, the force generated by the fluid pressure in front of the valve on the ball is all transmitted to the bearing, and the ball will not move toward the valve seat, so the valve seat will not bear excessive pressure, so the fixed ball valve It has small torque, small valve seat deformation, stable sealing performance and long service life. It is suitable for high pressure and large diameter occasions. The advanced spring pre-valve seat assembly has self-tightening characteristics to achieve upstream sealing. Each valve has two valve seats, which can be sealed in each direction, so the installation has no flow restrictions and is bidirectional. This valve is generally installed horizontally.
<:rr, , Fixed ball valves have two-piece and three-piece valve body structures. The middle flange is connected with bolts. The seal is made of reinforced polytetrafluoroethylene embedded in a stainless steel ring. The rear part of the steel ring is There is a spring to ensure that the valve seat is close to the ball and maintains a seal. The upper and lower valve stems are equipped with bearings to reduce friction and save effort in operation. There is an adjustment piece at the bottom of the small shaft to ensure the joint position between the ball and the sealing ring. Full bore: The flow aperture of the valve is consistent with the inner diameter of the pipeline to facilitate pipeline cleaning.
