A fluid extrusion groove is formed in the middle of the inner wall of the rubber sealing body, a silicon rubber ring groove A is formed in the left inner wall, and a silicon rubber ring groove B is formed in the right inner wall; the fluid extrusion groove has the function that when fluid passes through, the fluid is extruded to the left side and the right side under pressure, so that the rubber sealing body is in extrusion contact with the connected pipeline, and the purpose of enhancing the sealing performance is achieved.

The silica gel ring A is arranged in a silica gel ring groove A on the right inner wall of the rubber sealing body.

The silica gel ring B is arranged in a silica gel ring groove B on the left inner wall of the rubber sealing body.

The silica gel ring A and the silica gel ring B are in further flexible close contact with the two connected pipelines, so that the problem of untight sealing caused by rough pipelines is solved, and the optimal sealing effect and purpose are achieved.

Go up the inner wall centre of tile and be equipped with the sealing member groove, the upper and lower both sides in sealing member groove are equipped with the connecting pipe draw-in groove respectively, and connecting pipe draw-in groove outer end is equipped with the chamfer, go up the tile about both ends be equipped with respectively and close the ear of tile, the middle part that closes the ear of tile is equipped with the connecting hole.

The upper tile and the lower tile have the same structure and are mutually matched with each other when being installed.

The upper tile and the lower tile have the effects that the pipeline can be clamped by mutually combining circles, and the purpose of connecting the pipeline can be achieved by assembling an upper bolt and a nut.

The invention has the beneficial effects that: the problems of reduced sealing performance and generated fluid leakage caused by the deformation of the sealing element due to the contact corrosion of the fluid and the change of positive and negative pressure can be solved, the form and the sealing performance of the sealing element can be maintained, and the purpose of solving the fluid leakage is achieved; the flexible contact seal can solve the problem of fluid leakage caused by rough pipelines, can ensure the connection and sealing of the pipelines, brings economic benefits to using enterprises, reduces unnecessary loss, saves maintenance cost, saves energy, protects environment, and brings immeasurable beneficial effects to enterprises, society and countries.
