Embodiment 1
[0014] As shown in FIG. 1 , the rolling type end face sealing diaphragm 1 is in the shape of a disc, with an annular arc boss 2 on the inner surface and a flange 3 on the outer circumference. The rolling end face sealing diaphragm is made of two kinds of materials, the inner and outer layers are sealing diaphragm, and the middle layer is mesh braid 4; the sealing diaphragm is made of rubber and other materials with high elasticity, and the mesh braid is made of high strength Cotton thread, carbon fiber and other materials.
[0015] As shown in Figures 1 and 2, the rolling end face seal diaphragm works like this: the flange 3 on the outer circumference of the rolling end face seal diaphragm is installed on the cylinder body 5, which acts as a seal equivalent to the ○ ring, and the The high-pressure chamber in the cylinder body 5 is isolated from the normal pressure chamber; when the piston 6 in the cylinder body 5 moves axially within a certain range, the diaphragm at the ring-...
