Specific embodiment
Further illustrate a specific embodiment of the invention with reference to the accompanying drawing.
The present invention is mainly made of vacuum tube 1, detection pipe 13, sealing ring 15, it is characterised in that: the vacuum tube 1 and institute
It states and is connected between detection pipe 13 by bellows 5,13 front end of detection pipe is equipped with ball sealer 14.
Draw-in bar bracket 2 is provided in the bellows 5, the draw-in bar bracket 2 passes through interior drawing with the ball sealer 14
Bar 3 is connected as an entirety, and outside link bracket 4 is arranged outside the bellows 5, and the outside link bracket 4 passes through outside link 6 and sets
It sets the slip ring 12 outside the detection pipe 13 and is connected as an entirety.
5 upper end of bellows is connect by fastening clamp 9 with the vacuum tube 1, lower end pass through fastening clamp 9 with it is described
Detection pipe 13 connects.
The ball sealer 14 is pressed on the opening of the detection pipe 13 by spring 11, will test the opening sealing of pipe 13, institute
It states spring 11 to be supported in spring support seat 10, the spring support seat 10 is arranged on the inner wall of the detection pipe 13.
Slip ring 12 and sealing ring 15,15 elastically deformable of sealing ring, institute are provided on the outer wall of the detection pipe 13
Stating slip ring 12 can slide up and down along the outer wall of the detection pipe 13.
Clamping cylinder 8 is further fixed on the outer wall of the detection pipe 13, the bottom surface of the clamping cylinder 8 has aperture, makes described
Outside link 6 can pass through the clamping cylinder 8 and connect with the slip ring 12.
Preferably, the vacuum tube 1, the bellows 5, the detection pipe have sealing flange 7, the sealing flange 7
Can intersect cooperation, to enhance the leakproofness of pipeline.
Preferably, the draw-in bar bracket 2 is set at the major diameter of the top of the bellows 5, the draw-in bar bracket 2
For one cross bar of band in circle.
Preferably, there are external screw thread in internal screw thread on the ball sealer 14,3 end of draw-in bar, pass through screw thread between the two
Connection.
Preferably, the outside link bracket 4 is set at the path of the top of the bellows 5, and is set in described
The lower section of pull rod bracket 2,6 bracket 4 of outside link are a circular ring shape.
