Problems solved by technology

[0004] When the existing release interface leads out the branch pipeline, it is often necessary to cut off the transportation of natural gas, and then open the release interface to connect, otherwise it will cause natural gas leakage
However, cutting off natural gas will affect the normal transportation of natural gas pipelines, bring inconvenience to people's lives, and also bring economic losses to construction units or operating units

Abstract

The invention discloses a natural gas pipeline capable of branching, and relates to the technical field of natural gas pipelines. The natural gas pipeline at least includes a pipe body. A releasing mechanism is arranged on the pipe body. The releasing mechanism at lease includes a releasing pipe, a gas outlet pipe, a releasing valve and a detachable driving rod. A sealing separating plate for sealing a pipe hole of the releasing pipe is transversely in the releasing pipe. An ash collection cylinder is positioned at the opening of the lower end of the releasing pipe located in the pipe body. The gas outlet pipe includes a main pipe and a branch pipe. A sleeve pipe is coaxially arranged in the main pipe. A hole opener capable of sliding up and down along the inner wall of the sleeve pipe isarranged in the sleeve pipe. The hole opener and the inner wall of the sleeve pipe are in a sliding sealing fit manner. The invention provides the natural gas pipeline capable of hole-opening and branching without cutting off natural gas transportation.

Description

technical field [0001] The invention relates to the technical field of natural gas pipelines, in particular to a branchable natural gas pipeline. Background technique [0002] Existing natural gas pipelines often use PE pipe fittings, that is, polyethylene pipe fittings. The pipe fittings made of this material have the advantages of strong corrosion resistance, convenient installation and affordable price. [0003] During the use of natural gas pipelines, sometimes it is necessary to open holes for diversion, and some pipe fittings will also reserve a release interface. It is more convenient and reliable to lead out the branch pipeline through the release interface than to lead out the branch pipeline on a smooth pipe wall. [0004] When the existing release interface leads out to branch pipelines, it is often necessary to cut off the transportation of natural gas, and then open the release interface for connection, otherwise natural gas leakage will occur. However, cuttin...
