The Q47F/Q47H/Q47Y/Q347Y worm gear fixed ball valve is a new generation of high-performance ball valves, suitable for long-distance pipelines and general industrial pipelines.The Q47F/Q47H/Q47Y/Q347Y worm gear fixed ball valve is a new generation of high-performance ball valves, suitable for long-distance pipelines and general industrial pipelines. Its strength, safety, and resistance to harsh environments have been specially considered during the design process. Its strength, safety, and resistance to harsh environments have been specially considered during the design process. It is suitable for various corrosive and non-corrosive media. It is suitable for various corrosive and non-corrosive media. Compared with the floating ball valve, when working, the force generated by the fluid pressure before the valve on the ball is fully transmitted to the bearing, preventing the ball from moving towards the valve seat, so the valve seat will not bear excessive pressure. Compared with the floating ball valve, when working, the force generated by the fluid pressure before the valve on the ball is fully transmitted to the bearing, preventing the ball from moving towards the valve seat, so the valve seat will not bear excessive pressure. Therefore, the fixed ball valve has a smaller torque, less valve seat deformation, stable sealing performance, and a long service life, and is suitable for high-pressure and large-diameter applications. Therefore, the fixed ball valve has a smaller torque, less valve seat deformation, stable sealing performance, and a long service life, and is suitable for high-pressure and large-diameter applications. The spring-preloaded valve seat assembly has self-tightening characteristics and realizes upstream sealing. The spring-preloaded valve seat assembly has self-tightening characteristics and realizes upstream sealing. Each valve has two valve seats, and each direction can seal, so there is no flow direction restriction during installation. Each valve has two valve seats, and each direction can seal, so there is no flow direction restriction during installation.

The characteristics of the worm gear fixed ball valve 

1. Operation is effortless: The sphere is supported by upper and lower bearings, reducing friction and eliminating the huge sealing load caused by the imported pressure pushing the sphere against the sealing seat, which results in excessive torque.

2. Reliable sealing performance: The PTFE elastic material sealing ring is embedded in the stainless steel valve seat. The metal valve seat tail end has no spring, ensuring sufficient preload for the sealing ring. When the sealing surface of the valve wears during use, under the action of the spring force, the valve continues to maintain good sealing performance.

3. Fireproof structure: To prevent the polytetrafluoroethylene sealing ring from burning and causing a large leakage that may intensify the fire, a fireproof sealing ring is set between the sphere and the valve seat. When the sealing ring burns, under the action of the spring force, the valve seat sealing ring is quickly pushed onto the sphere, forming a metal-to-metal seal, achieving a certain degree of sealing effect.

4. Automatic pressure relief function: When the pressure of the medium in the valve chamber abnormally rises and exceeds the pre-tightening force of the spring, the valve seat retreats and detaches from the sphere, achieving the effect of automatic pressure relief. After pressure relief, the valve seat automatically resets.

5. Drainage pipeline: Both the upper and lower parts of the valve body are equipped with drainage holes. They can be used to check if the valve seat has leaked. During operation, when the valve is fully open or fully closed, the pressure in the middle chamber is relieved, and the packing can be replaced directly.
