The stainless steel flanged ball valve adopts a hard sealing structure with reliable sealing performance, and it also has the dual characteristics of adapting to high and low temperature.

     The pressure on the sealing surface of the stainless steel flange ball valve is the effect of the torque of the transmission device and the medium pressure on the valve plate. When the medium pressure is large, the surface of the valve plate and the cover of the valve seat will be squeezed and tightened, so that the sealing effect will be stronger. it is good.

     The sealing between the valve plate and the valve seat depends on the driving device, and the pressure of the reverse medium increases, the unit positive pressure between the valve plate and the valve seat is less than the medium pressure, and the existing deformation can compensate the tight pressure on the sealing surface of the valve plate and the valve seat. to automatic compensation.

     The soft and hard multi-layer sealing ring is installed on the valve plate, which is directly installed on the valve body, and an adjusting ring is added between the pressure plate and the valve seat, which is a very ideal two-way hard sealing method.
