1. Uvedba krogličnega ventila iz nerjavečega jekla
V primerjavi s plavajočim krogelnim ventilom se sila, ki jo povzroča tlak tekočine pred ventilom na krogli, prenese na ležaj, zato se krogla ne premakne na sedež ventila, zato sedež ventila ne bo prenašal preveč ;
Poleg tega ima fiksni krogelni ventil iz nerjavečega jekla majhen navor, majhno deformacijo sedeža ventila, stabilno tesnjenje in dolgo življenjsko dobo, kar je primerno za visokotlačne in velike premere.

3.ZnačilnostiKrogelni ventil iz nerjavečega jekla
1) Nerjaveče 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 Nerjaveče 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) Nerjaveče 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) Nerjaveče 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;
