摘要： A non-sliding gate valve includes a valve housing and a valve body, the valve body having a paired valve plate and a counter plate disposed within the valve housing in parallel with each other. Also included are a pair of inner supports, each made of a metallic circular plate and arranged in parallel with each other, an outer support arranged outside the inner supports, and a pair of annular elastic connecting sheets arranged radially between the inner and outer supports and in parallel with each other, with a gap being left therebetween. The valve and counter plates are sealingly connected to the confronting inner supports, respectively; and the inner and outer supports are sealingly secured at their peripheries to the annular sheets at their inner and outer diameter portions, respectively. The annular sheets are each formed with at least one annular corrugation on their surfaces, a sealed space being formed between the inner and outer supports and the annular sheets so as to be connected to a pressurized fluid source.
