[0036] Please refer to Figures 1-5 The utility model provides a technical scheme: a kind of PE ball valve auxiliary device, including the length of extension pipe 1 for extending double diffusion PE ball valve in pipe guard and the gas guide pipe 2 for conveying double diffusion PE ball valve in diffusion valve 36 released gas, the extension pipe 1 is equipped with support strip 3 between gas guide pipe 2, and the extension pipe 1 and gas guide pipe 2 are all with support strip 3 detachable connection.

[0037] The length of the protection pipe of the double-dispersion PE ball valve is extended by the extension pipe 1, and the opening end of the protection pipe extends towards the opening direction of the valve well to facilitate the related technical personnel to insert the wrench into the opening of the protection pipe, and then to open and close the operation cap to complete the opening and closing operation on the ground without entering the narrow valve well, thereby providing convenience for the opening and closing operation of the double-dispersion PE ball valve and reducing the risk of oxygen deficiency and asphyxiation of the related technical personnel.

[0038] At the same time, the released gas at the dispersion valve 36 of the double-dispersion PE ball valve is transported by the gas guide pipe 2 to the vicinity of the opening of the valve well to facilitate the dissipation of the gas to the outside of the valve well, thereby reducing the content of the accumulated gas in the valve well and reducing the probability of poisoning of the related technical personnel due to inhaling the gas.

[0039] In the embodiment, the first pipe clamp 31 in the shape of U is fixedly connected to the middle part of the support strip 3, and the extension pipe 1 is clamped in the first pipe clamp 31, and the extension pipe 1 is perpendicular to the support strip 3.

[0044] In the embodiment, two strip-shaped holes 33 corresponding to the two second pipe clamps 32 are formed at the two ends of the support strip 3, and the strip-shaped holes 33 extend along the length direction of the support strip 3. The two strip-shaped holes 33 are each provided with a slide rod 34.

[0045] One end of the slide rod 34 is fixedly connected with the corresponding second pipe clamp 32, and the other end extends out of the strip-shaped hole 33 towards the side away from the second pipe clamp 32.

By inserting the slide rod 34 into the strip-shaped hole 33, the slide rod 34 can drive the second pipe clamp 32 to rotate around the axis of the slide rod 34, so that the second pipe clamp 32 drives the air guide pipe 2 to rotate and tilt, and the tilt angle of the air guide pipe 2 is freely adjusted, so that the bottom end of the air guide pipe 2 is aligned with the output end of the diffusion valve 36 in the double diffusion PE ball valve, and the influence of the bending of the double diffusion PE ball valve during use on the installation of the air guide pipe 2 is reduced. The slide rod 34 can slide along the length direction of the strip-shaped hole 33, so as to adjust the spacing between the second pipe clamp 32 and the first pipe clamp 31.

[0047] In the embodiment, recesses 331 extending along the length direction of the strip-shaped hole 33 are formed on the opposite two planes in the strip-shaped hole 33, and a convex ring 341 is coaxially fixedly connected to the middle part of the slide rod 34.

[0051] Under the blocking action of the convex ring 341, the second pipe clamp 32 is limited to be embedded in the strip-shaped hole 33 or to pass through the strip-shaped hole 33. The support strip 3 is clamped by the cooperation of the convex ring 341 and the clamping block 35. By rotating the clamping block 35, the clamping block 35 is close to the convex ring 341, so that the clamping block 35 and the convex ring 341 press the support strip 3. Under the action of the friction between the clamping block 35, the convex ring 341 and the support strip 3, the free sliding of the clamping block 35 and the convex ring 341 is limited, so as to achieve the purpose of locking the second pipe clamp 32.

[0060] In the embodiment, the other end of the air guide pipe 2 is fixedly connected with the double-discharge PE ball valve 36 and is communicated with the input end of the double-discharge PE ball valve 36.

[0061] When the air guide pipe 2 needs to be installed on the output end of the double-discharge PE ball valve, the double-discharge valve 36 on the top end of the air guide pipe 2 is manually closed, then the double-discharge valve 36 in the double-discharge PE ball valve is opened, and the double-discharge valve 36 on the air guide pipe 2 replaces the double-discharge valve 36 in the double-discharge PE ball valve, so that the double-discharge valve 36 on the top end of the air guide pipe 2 is close to the valve well opening, and the related technical personnel can control the opening and closing of the double-discharge valve 36 on the ground, without entering the valve well, which provides convenience for the work of the related technical personnel and protects the safety of life and property.
