Valvola a sfera fissa in acciaio inossidabile

1.Introduzione della valvola a sfera fissa in acciaio inossidabile

Rispetto alla valvola a sfera flottante, la forza prodotta dalla pressione del fluido davanti alla valvola sulla sfera è tutta trasferita al cuscinetto, quindi la sfera non si sposterà verso la sede della valvola, quindi la sede della valvola non sopporterà troppa pressione ;
Inoltre, la valvola a sfera fissa in acciaio inossidabile ha una coppia ridotta, una piccola deformazione della sede della valvola, prestazioni di tenuta stabili e una lunga durata, adatta per applicazioni ad alta pressione e di grande diametro.

3.Caratteristiche diValvola a sfera fissa in acciaio inossidabile

1) Inossidabile steel fixed ball valve has two-piece and three piece valve body structures. The middle flange is connected by bolts, and the seal is made of reinforced polytetrafluoroethylene inlaid into the stainless steel ring. There is no spring at the back of the steel ring to ensure that the valve seat is close to the ball and keep the seal.
2) There is no PTFE bearing on the upper and lower valve stems of the Inossidabile steel fixed ball valve, which reduces friction and saves labor. There is no adjusting plate at the bottom of the small shaft to ensure the joint position between the ball and the sealing ring. Full bore design for pipeline cleaning.
3) Inossidabile steel fixed ball valve automatic pressure relief function: when the stagnant medium pressure in the valve cavity rises abnormally and exceeds the preload of the spring, the valve seat will retreat from the ball to achieve the effect of automatic pressure relief, and the valve seat will reset automatically after pressure relief.
4) Inossidabile steel fixed ball valvedrain pipeline: the drain valve L is set up above and below the valve body to check whether the valve seat leaks. During operation, when the valve is fully open or closed, the pressure in the middle chamber can be removed and the packing can be directly replaced; Can be discharged in the cavity retention, reduce the pollution of the medium to the valve. Auxiliary seal setting system;
