·                                 Fixed ball valve is a new generation of high performance ball valve. It is suitable for long-distance pipelines and general industrial pipelines. Its strength, safety and harsh environment are specially designed for various corrosive and non-corrosive properties. medium. Compared with the floating ball valve, when working, the force generated by the pre-valve fluid pressure on the ball is transmitted to the bearing, and the ball is not moved to the valve seat, so the valve seat does not withstand excessive pressure, so the fixed ball valve The torque is small, the valve seat deformation is small, the sealing performance is stable, and the service life is long, and is suitable for high pressure and large diameter occasions. An advanced spring pre-valve assembly with self-tightening for upstream sealing. Each valve has two seats that seal in each direction, so the installation has no flow restriction and is bidirectional. This valve is generally installed horizontally.
The fixed ball valve has two-piece and three-piece valve body structure. The middle flange is bolted. The seal is made of reinforced PTFE embedded in the stainless steel ring. There is no spring at the rear of the steel ring to ensure that the valve seat is close to the ball. seal. There is no PTFE bearing on the upper and lower valve stems, which reduces friction and saves effort. There is no adjustment piece at the bottom of the small shaft to ensure the position of the ball and the sealing ring. Full bore: The valve flow orifice is the same as the inner diameter of the line for the pipeline to be cleaned. Fixed ball valve for medium: water, gas, oil, natural gas and acid-alkaline corrosive media. Applicable temperature: -196 ~ 350 °C, drive mode: manual, worm gear, pneumatic, electric, hydraulic and so on.
Fixed ball valve product features
1. Low effort: The ball is supported by the upper and lower bearings to reduce friction and eliminate excessive torque caused by the large sealing load caused by the inlet pressure pushing the ball and the sealing seat.
2 , the sealing performance is reliable: PTFE single material sealing ring is embedded in the stainless steel valve seat, the metal valve seat end is provided with a spring to ensure sufficient pre-tightening force of the sealing ring, when the sealing surface of the valve is worn during use, under the action of spring The valve continues to guarantee good sealing performance.
3 , fire-proof structure: In order to prevent the occurrence of sudden heat or fire, the PTFE seal ring burned, a large leak occurred, and promote the fire, a fire seal ring is set between the ball and the valve seat, when the seal ring burns, Under the action of the spring force, the seat ring is quickly pushed onto the ball to form a metal-to-metal seal, which has a certain degree of sealing effect. The fire test conforms to the APl6FA and APl607 standards.
4. Automatic pressure relief function: When the pressure of the medium in the valve cavity is abnormally increased beyond the preload of the spring, the valve seat retreats out of the sphere to achieve the effect of automatic pressure relief. The valve seat is automatically reset after pressure relief.
5 , drain pipe: the upper and lower sides of the valve body are provided with drainage å‘L , can check whether the valve seat leaks, in the work, when the valve is fully open or fully closed, remove the pressure in the middle cavity, can directly replace the packing; can be discharged The cavity is retentate to reduce the contamination of the valve by the medium. Fixed ball valves are widely used in the cutting or circulation of conveying pipeline media such as food, medicine, petroleum, chemical, natural gas, steel, environmental protection, and papermaking. The device can also be cleaned by injecting a corresponding cleaning agent or lubricant into the device.
