Nuts 4 are screwed on the pipe body of the screw pipe 3, and elastic hanging plates 9 are provided on the outer ring surface of the connecting plate 1. Both ends of the elastic hanging plate 9 are fixed with clamping strips 10; the connecting plate 1 is arranged between the flange at the end of the gate valve and the flange of the conveying pipeline, and the two groups of screw pipes 3 are respectively inserted into the flanges on both sides. After the connecting plates 1 are installed at both ends of the gate valve, the gate valve is suspended between the two sections of the conveying pipeline, and the nuts 4 are screwed on the nuts 4 and locked to complete the installation and fixation of the gate valve; it further solves the problem that the existing gate valve needs to be supported by supporting equipment while being installed with bolts; the gate valve can be suspended between the two flanges, and the hanging structure acts as a screw for the bolts.

[0025] Embodiment 2

[0026] See attached Figure 5 As shown, on the basis of Example 1, in order to realize the connection between the flange at the end of the gate valve and the flange of the conveying pipeline, a plurality of reserved holes 2 are provided, and the plurality of reserved holes 2 are arranged in a circular shape, and a plurality of screw tubes 3 are provided in each group, and the screw tubes 3 and the reserved holes 2 correspond one to one, and the inner diameter of the screw tubes 3 is smaller than the aperture of the reserved holes 2; a truncated cone ring is integrally formed at one end of the screw tube 3 away from the connecting plate 1, and a plurality of notches 5 are provided on the surface of the truncated cone ring, and a rubber clamp 6 is fixed on the surface of the notch 5, and the thickness of the rubber clamp 6 is greater than the height of the notch 5. After the nut 4 is sleeved and screwed on the screw tube 3, the rubber clamp 6 is clamped between the nut 4 and the screw tube 3 to generate elastic deformation; a rubber gasket 7 is fixed on the surface of the connecting plate 1, and the rubber gasket 7 is an arc-shaped plate-like structure, and two rubber gaskets 7 are provided, and the two rubber gaskets 7 are symmetrically distributed about the connecting plate 1.

[0027] After the two groups of screw tubes 3 are respectively plugged into the flange at the end of the gate valve and the flange of the conveying pipeline, ensure that the flanges at both ends of the gate valve are connected to the two sections of the conveying pipeline through the connecting plate 1. At this time, the screw tube 3 plays a carrying role, that is, the gate valve does not need to be supported and will not fall off; then the nut 4 is sleeved and screwed on the screw tube 3 and locked. At this time, the screw tube 3 is used as the screw of the bolt, that is, the screw tube 3 has two uses. The reason why a rubber clamp 6 is installed at one end of the screw tube 3 is that after the nut 4 is locked, the rubber clamp 6 is clamped between the nut 4 and the screw tube 3 to produce elastic deformation to prevent the nut 4 from loosening.
