The high-pressure ball valve is a ball valve that uses a new type of sealing material as the valve seat and is sealed by a similar product PTFE. The service life is increased by 3-5 times. The high-pressure ball valve has the advantages of stable performance, reliable sealing, low friction, light switch, high temperature resistance, wear resistance, oil resistance, corrosion resistance, and long service life. The high pressure ball valve has the same structure length as the stop valve, plunger valve, and drain valve. Expanded the scope of use of ball valves, widely used in petroleum, chemical, rubber, paper, pharmaceutical and other industries, can replace stop valves, plunger valves, fast blowdown valves. Applicable medium: acids such as water, steam, heat transfer oil, etc., operating temperature: ≤300℃.
The ball and sealing ring in the high-pressure ball valve adopts special processing technology and new sealing materials to make the surface roughness and roundness of the ball meet the standard requirements, thereby improving the sealing performance, service life and high temperature resistance. Turn the handle clockwise to drive the valve stem to drive the sphere to rotate, so that the medium can pass smoothly. Structural characteristics of high-pressure ball valve: When the stagnant pressure in the cavity of the high-temperature ball valve exceeds the pre-tightening force of the spring abnormally, the valve seat retreats and separates from the sphere to achieve the effect of automatic pressure relief, and the valve seat automatically resets after pressure relief. In the event of a fire or abnormal heating of the high-pressure ball valve, the seat sealing ring is burnt or softened. Under the action of the spring and the medium pressure, the spherical part of the support ring and the ball will form a metal-to-metal contact to achieve a temporary sealing effect and prevent The fire expanded further. The high-pressure ball valve divides the valve body into three parts along the cross section perpendicular to the axis of the valve channel at the two valve seats. The whole valve is symmetrical along the stem axis. It is mainly used to cut off, distribute and change the direction of medium flow in the pipeline. Its large pivot structure ensures accurate ball position under high pressure, ensuring good valve operation performance; standard valve seat adopts a spring structure, which pushes the valve seat to the ball, ensuring good two-way sealing performance for inlet and outlet; using its own The discharge valve in the valve body can discharge outward; the pivot adopts an anti-blowout protection structure to effectively prevent leakage; the low friction coefficient of the bearing reduces the torque to a small amount and facilitates the opening and closing of the valve; the valve stem and the valve body are effective Contact, so that the anti-static grounding device has superior performance. It has the advantages of excellent performance, high reliability, wide range of uses, and reasonable price. Structural features of high-pressure ball valve: The main feature of the floating ball valve is that the ball has no supporting shaft. The ball is held in a "floating" state by two valve seats. It is mainly used to cut off, distribute and change the direction of medium flow in the pipeline. The main features of the floating ball valve are the valve seat sealing design, the reliable inverted sealing valve sealing rod, the anti-static function, automatic pressure relief and locking device and other structural features.
