Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

A sealing connection pipe fitting for a vacuum system is shown in figure 1-2 and comprises pipe bodies 1 arranged at intervals oppositely and connectors 2 connected with the two pipe bodies 1 respectively, clamping rings 3 are fixedly connected to the shaft walls of the two pipe bodies 1 respectively, the clamping rings 3 are flush with the opening walls of the pipe bodies 1, and sealing devices are arranged on the two connectors 2.

As shown in fig. 1-2, an annular through groove 4 is formed in the connector 2, the pipe body 1 is located in the through groove 4, the diameter of the through groove 4 is larger than that of the pipe body 1, and the diameter of the outer wall of the clamping ring 3 is equal to that of the connector 2.

As shown in fig. 1-2, the opposite side walls of the two connectors 2 are provided with clamping grooves 5 arranged at opposite intervals, the two clamping grooves 5 are distributed on both sides of the axis of the connector 2, and the surfaces of the two clamping rings 3 which deviate from each other are fixedly connected with clamping blocks 6 matched with the clamping grooves 5.

As shown in fig. 1-2, the sealing device includes two fixing shells 7 covering the exterior of the connector 2 and disposed at opposite intervals, when the two fixing shells 7 are combined together, the inner wall of the fixing shell 7 matches with the exterior shapes of the tube body 1 and the connector 2, a rubber layer 8 is laid on the inner wall of the fixing shell 7, a water-swelling sealing strip 9 is disposed on the surface of the rubber layer 8, and a fixing member is disposed on the outer wall of the fixing shell 7.

As shown in fig. 1-2, the fixing member includes fixing blocks 10 fixedly connected to the outer axial walls of the two fixing cases 7 and oppositely disposed at intervals, the fixing blocks 10 are provided with threaded holes, the threaded holes are internally threaded with bolts 11, and the bolts 11 are threadedly connected with nuts 12.
