What are the characteristics of stainless steel flanged ball valves?


What is the stainless steel flange ball valve? Sphere ball with a fixed shaft is called a stainless steel flange ball valve.
The valve body has two valve seat seals, between them clamping a sphere, the ball has a through hole, the diameter of the hole is equal to the diameter of the pipe, said the full diameter ball valve; the diameter of the hole slightly smaller than the diameter of the pipe , Said reduced diameter ball valve. The ball is free to rotate in the valve seat seal by means of the valve stem. When the valve stem is rotated by 1/4 turn, the ball hole is perpendicular to the channel of the valve, and the preload force applied to the two valve seat seals is the same as that of the valve seat. And the media pressure will be tightly pressed in the ball on the outlet side of the valve seat seal, so as to ensure that the valve completely sealed.
Structure and Function of Stainless Steel Flange Ball Valve
Seal performance Advanced multi-seat structure: According to the user's different uses and requirements of the design of ordinary seat, flexible seat and other structures to ensure that the valve sealing performance and reliable; long life, reduce the valve operating torque.
2. Handle operation position and valve opening and closing position of the same: the correct installation of the handle for the handle and the channel parallel to the position of the handle to determine the valve opening to prevent misuse.
3. Valve fully open, fully closed position of the locking device: In order to prevent the opening and closing the valve malfunction, in the fully open, fully closed position set with a locking hole. The valve position can be locked to prevent other people from malfunctioning, as well as vibration and other causes of valve position malfunction to ensure the safety of equipment.
4. Stem anti-fly structure: the lower part of the design of the stem stem, the assembly will be stuck from the valve body to prevent the internal pressure of the valve stem fly out. At the same time can also be in the accident after the fire, stem and valve body sealing performance.
5. Anti-static function: in the use of flammable media such as low ignition of gasoline, natural gas, propane and other flammable media, should be considered to prevent static problems, in order to avoid the ball and PTFE seat between the Friction produces static electricity and explodes.
6. Fire protection structure: When an accident fire occurs, the seat, packing.
