Ball valves are used in oil, natural gas, coal and ore mining, refining and processing and pipeline transportation systems; in chemical products, medicine and food production; in hydropower, thermal power and nuclear power generation systems; in urban and industrial enterprises' water supply and drainage systems , Heating, and gas supply systems; in farmland irrigation and drainage systems; in metallurgical production systems, it can be widely used. It is an important mechanical product that is closely related to production, construction, and people's lives. The ball valve is sealed in various piping systems to cut off or connect the medium flow, so that the medium can be transported to various points according to a predetermined procedure.


1. Labor-saving operation: the ball is supported by the upper and lower bearings to reduce friction and eliminate the excessive torque caused by the huge sealing load formed by the imported pressure pushing the ball and the sealing seat.
2. Reliable sealing performance: PTFE unisexual material sealing ring is embedded in the stainless steel valve seat, and the end of the metal valve seat is equipped with a spring to ensure sufficient pre-tightening force of the sealing ring. When the sealing surface of the valve wears during use, it will be under the action of the spring. The valve continues to ensure good sealing performance.
3. Fireproof structure: In order to prevent the PTFE seal ring from being burnt due to sudden heat or fire, and large leakage occurs, which encourages the fire, a fireproof seal ring is set between the ball and the valve seat. When the seal ring is burned, Under the action of the spring force, the valve seat sealing ring is quickly pushed to the ball to form a metal-to-metal seal, which has a certain degree of sealing effect. The fire resistance test meets the requirements of AP16FA and API607 standards.
4. Automatic pressure relief function: When the pressure of the stagnant medium in the valve cavity rises abnormally and exceeds the pre-load of the spring, the valve seat retreats away from the sphere to achieve the effect of automatic pressure relief. After the pressure is relieved, the valve seat automatically recovers.
5. Drainage pipeline: Drain holes are set up and down the valve body to check whether the valve seat is leaking. During work, when the valve is fully open or fully closed, the pressure in the middle cavity can be removed, and the packing can be directly replaced; the middle cavity can be discharged. Retentate, reduce the pollution of the medium to the valve.
