Description
Technical Field
The utility model relates to a valve, in particular to fixed ball valve.
Background
The fixed ball valve is a new generation high-performance ball valve, is suitable for long-distance pipeline and general industrial pipeline, and its strength, safety and resistance to harsh environment are specially considered in the design process, so that it is applicable to various corrosive and non-corrosive media. Compared with a floating ball valve, when the ball valve works, acting force generated by fluid pressure in front of the valve on the ball body is completely transmitted to the bearing, the ball body cannot move towards the valve seat, and therefore the valve seat cannot bear overlarge pressure, so that the fixed ball valve is small in torque, small in deformation of the valve seat, stable in sealing performance and long in service life, and is suitable for high-pressure and large-caliber occasions. Advanced spring pre-seating assemblies, with self-tightening features, achieve upstream sealing. Each valve has two valve seats and can seal in each direction, so that the installation has no flow direction limitation and is bidirectional. The valve is generally mounted horizontally.
The existing fixed ball valve is unstable in structure, large in pressure generated on a valve seat, and easy to damage the valve seat for a long time, so that the sealing performance of the valve seat is reduced, leakage is easy to occur, and the service life of the valve seat is short.
