1. Panimula ng Hindi Kinakalawang na Asero Naayos na Ball Valve
Kung ikukumpara sa lumulutang na balbula ng bola, ang puwersang ginawa ng presyon ng likido sa harap ng balbula sa bola ay inililipat sa tindig, kaya't ang bola ay hindi lilipat sa upuan ng balbula, kaya't ang upuang balbula ay hindi magtatagal ng labis na presyon ;
Bukod dito, ang hindi kinakalawang na asero na nakapirming ball balbula ay may maliit na metalikang kuwintas, maliit na pagpapapangit ng upuan ng balbula, matatag na pagganap ng pag-sealing at mahabang buhay ng serbisyo, na angkop para sa mataas na presyon at malalaking mga application ng diameter.

3.Mga katangian ngHindi Kinakalawang na Asero Naayos na Ball Valve
1) Hindi kinakalawang 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 Hindi kinakalawang 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) Hindi kinakalawang 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) Hindi kinakalawang 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;
