Suitable for long-distance pipelines and general industrial pipelines, its strength and resistance to harsh environments have been considered in the design, and it is suitable for 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 transmitted to the bearing, which will not make the ball move towards the valve seat, so the valve seat deformation is small, the sealing performance is stable, and the use is long. It is suitable for high-pressure and large caliber occasions. The spring pre valve seat component has self tightening characteristics to achieve upstream sealing. Each valve has two valve seats, which can seal in each direction, so there is no flow restriction during installation, and it is bi-directional. This valve has two types of valve body structures: two-piece and three piece. The middle flange is connected by bolts, and the seal is made of reinforced polytetrafluoroethylene embedded in a stainless steel ring. The rear of the steel ring is equipped with a spring to make the valve seat tightly adhere to the ball, which conforms to the seal. Both the upper and lower valve stems are equipped with PTFE bearings to reduce friction and make operation effortless. There is no adjusting plate at the bottom of the small shaft to ensure the joint position between the ball and the sealing ring. Adopting a full bore structure to ensure that the valve flow hole is consistent with the inner diameter of the pipeline for pipeline cleaning.
