Low price for Double Offset Butterfly Valve - heavy duty double gate air sealed knife gate valve with airbag – Jinbin Valve Detail:
heavy duty double gate air sealed knife gate valve
The air sealed knife gate valve seat structure design adopts two different sealing mechanisms in the positive and reverse directions. The positive direction is a replaceable combined structure, which is fixed on the valve body by PTFE sealing ring; the reverse is the replaceable elastic compensation sealing combination structure, which is composed of air bag. By inflating and losing air to the air bag, the air bag forms an axial displacement, and the change caused by the gate plate translation is compensated, The first is to ensure the pre pressure of the reverse sealing of the ram and effectively ensure the sealing; the second is to reduce the opening and closing force of the ram: the material of the air bag should bear an internal pressure of 1.6Mpa at 200 ° high temperature (the air pump providing air source for the air bag is required to be more than 1.6Mpa).
