[0022] The embodiment of the present application provides a pipeline connection device for a natural gas pipeline valve, which solves the problem that the existing pipeline valve is prone to shaking after installation, which will cause instability in the interface. At the same time, when the clamp is used to restrain the hose, the contact area with the hose surface is small, the pressure is large, and it is easy to deform excessively, which makes the interface unstable, causes cracks or aging after a long time, and reduces the life of the interface.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The utility model discloses a pipeline connection device for a natural gas pipeline valve according to the attached Figure 1-4 As shown, it includes a valve body 1, the bottom of the valve body 1 is fixedly connected to a position adjustment seat 2, and the position adjustment seat 2 is provided with a bracket assembly fixed to the wall;

[0025] The bracket assembly includes a wall fixing plate 5 fixed to the wall and a guide rail rod 501 arranged on the wall fixing plate 5, and the position adjustment seat 2 is sleeved on the guide rail rod 501;

[0026] Hose butt pipes 3 are provided at both ends of the valve body 1, and a clamping assembly for reinforcing the sleeved hose is provided on the hose butt pipe 3. The clamping assembly includes a support seat 4 arranged on the position adjustment seat 2, and a station plate 401 is provided on the support seat 4. A screw rod 402 is threadedly connected to the station plate 401, and an arc-shaped clamping block 403 is rotatably connected to the screw rod 402.

[0027] Furthermore, multiple groups of anti-slip clamps 301 that are clamped with the hose are fixedly connected to the hose-to-hose pipe 3. The interface between the hose-to-hose pipe 3 and the hose is clamped between two groups of arc-shaped clamping blocks 403. The multiple groups of anti-slip clamps 301 facilitate clamping of the inner wall of the natural gas hose, so that the natural gas hose and the hose-to-hose pipe 3 are not easy to loosen after docking.

[0028] Furthermore, a lateral support rod 404 is fixedly connected to the arc clamping block 403, and the lateral support rod 404 is slidably connected to the standing plate 401. The arranged lateral support rod 404 can laterally support the arc clamping block 403 and stabilize the force.

[0029] A rotating handle 405 is provided on the screw rod 402, and the rotating handle 405 makes it easier and more convenient to rotate the screw rod 402.

[0030] Furthermore, a reinforcing rib 406 is fixedly connected between the support base 4 and the standing plate 401 . The provided reinforcing rib 406 makes the support base 4 and the standing plate 401 fixed and stable and not easy to deform.
