Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] A non-relief opening device for pipe fittings, see Figure 1 to Figure 12 , including two screw rods 4, the two screw rods 4 are arranged in parallel, and the two screw rods 4 are sequentially positioned with a clamping plate 1, a sealing plate 2 and a positioning plate 3, and the clamping plate 1, the sealing plate 2 and the positioning plate 3 are fixed in parallel by the nuts screwed on the screw rod 4, and can be disassembled or adjusted by adjusting the distance between the adjacent plates. The bayonet 101 that matches the connecting arm of the ball valve 12 is provided on the clamping plate 1, such as figure 2 shown. A sealing end cover 5 is provided on the side of the sealing plate 2 towards the clamping plate 1, such as Figure 4 , Figure 5 As shown, the sealing end cap 5 is used to seal one end port of the ball valve 12, t...

Abstract

The invention discloses non-decompression opening equipment for a pipe fitting, relating to the technical field of a fuel pipeline dial-up connected branch opening. The non-decompression opening equipment comprises two screws which are arranged in parallel, and a clamping plate, a sealing plate and a positioning plate are sequentially positioned on the two screws from front to back; a piston barrel is arranged between the positioning plate and the sealing plate, a piston is arranged in the piston barrel, a tapping cutter is arranged on the lower side of the piston, and the upper end of the tapping cutter and the lower end of the piston are connected through a connecting rod which penetrates through the sealing plate; a vent hole is formed in the piston barrel and penetrates through the inner wall and the outer wall of the piston barrel, and a vent valve is arranged on the vent hole; and a test hole is formed in the piston barrel and penetrates through the inner wall and the outer wall,and an atmospheric pressure tester is arranged on the test hole. in order to solve the problem that the connection with a bypass pipeline can be conducted only by closing the fuel pipeline, the invention provides a non-decompression opening equipment which is used for the pipe fitting and can be connected with the bypass pipeline without closing the fuel pipeline.

Description

technical field [0001] The invention relates to the technical field of gas pipeline dial connection, in particular to a non-reducing pressure opening device for pipe fittings. Background technique [0002] In recent years, with the rapid development of my country's economy and the acceleration of urbanization, polyethylene gas pipelines have also developed rapidly. With the construction and development of cities and towns, the traditional method of opening holes in the original main pipeline and connecting bypass pipes has been encountered. Yes, stop the gas pipeline first, cut off the gas pipeline, install a tee joint, and then connect the bypass pipe to the tee joint, or shut down the gas pipeline, open a hole in the gas pipeline, and then Install an electric fusion straight-through saddle pipe fitting on the opening, and connect the bypass pipe fitting to the electric fusion straight-through saddle pipe fitting. However, gas shutdown has a large impact on buried pipeline p...
