HHQ971 series electric thin ball valve has the remarkable features of short structural length, light weight, convenient
installation and material saving, and has a good thermal insulation effect on jacketed ball valves. In addition, the valve seat adopts elastic sealing structure, which is reliable and easy to open and close. Equipped with fire-resistant structure, in case of fire, it can still be operated reliably and has good sealing performance.
According to user's requirements, anti-static structure can be provided.
A 90-degree switch locating piece with holes is set, which can be locked as required to prevent misoperation.
main feature
The ball valve with small fluid resistance is the smallest of all valves, and even the reducing ball valve has quite
small fluid resistance. . Thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.
The sealing performance of the valve seat is good. The sealing ring made of elastic materials such as PTFE is easy to seal, and the sealing ability of the ball valve increases with the increase of medium pressure.
.The sealing of the valve stem is reliable. Because the valve stem only moves in imitation of rotation and does not move up and down, the packing seal of the valve stem is not easy to be damaged, and the sealing ability increases with the increase of the pressure of the medium. .
Because PTFE and other materials have good self-lubrication, the friction loss with the ball is small,so the service life of the ball valve is long.
The lower-mounted valve stem and the convex step at the head of the valve stem prevent the valve stem from spraying out. If the valve stem seal is damaged by fire, metal contact can be formed between the convex step and the valve body to ensure the valve stem seal. Anti-static function: a spring is arranged between the ball, the valve stem and the valve body, which can lead out the static electricity generated in the switching process.
