Taper convex block.
Preferably, the lead screw is tightly connected by pressure cap and the gate valve cap.
Preferably, packing seal is equipped between the lead screw and the joint face of the gate valve cap.
Preferably, the joining place of the left sealing cover and right sealing cover is equipped with sealing strip.
Compared with prior art, the utility model is advantageous in that: the bottom end of the utility model brake valve body is equipped with close
Sealing groove, flashboard are inserted in seal groove, can achieve sufficiently sealed effect, avoid flashboard bottom end and brake valve body Long Term Contact,
Leading to flashboard bottom end, deformation occurs, influences sealing effect, and left sealing cover and right sealing cover play block media and enter seal groove, shadow
Ring the use of valve.
Detailed description of the invention
Fig. 1 is a kind of overall structure diagram of leakproof sandwich valve in an embodiment of the present invention.
Specific embodiment
