Description

A kind of pipeline quick union

Technical field

The utility model relates to a kind of pipe coupling, more particularly, relates to a kind of pipeline quick union.

Background technique

Traditional pipeline connecting head generally is through in the pipe fitting housing, internal thread being set, and the pipe port is provided with outside thread; But because of being connected and carrying out simultaneously between pipe fitting and two pipes, generally all be to twist pipe fitting to be incorporated on the mounted pipe earlier, and then twist another pipe to close and be connected on the pipe fitting; Realize the seamless link of two pipes; And pipe is a kind of oblong object, rotates with it and twists that to close that pipe realizes being threaded be trouble, and particularly the installation of pipe fitting often is again in some narrow spaces; Bring very big inconvenience to installation, influenced working efficiency.The outside thread of tube end processes often temporarily; There are not unified specification standards with the internal thread of pipe fitting; Often occur pipe fitting when making installation and adorn phenomenon not in place, also guaranteed not the sealing of pipe fitting, because the pipe two ends are all fixed; Keep in repair or when safeguarding the dismounting trouble through pipe fitting.Therefore, how to address the above problem, become problem demanding prompt solution.

The model utility content

The utility model technical problem to be solved provides a kind of pipeline quick union with easy for installation, quick detachable and good seal performance.

A kind of pipeline quick union of the utility model; Comprise the connection body; Its end is provided with the outer screw socket and the rotation set of bolt with it, and the end that is threaded of its described body is provided with annular groove, and the inwall of described rotation set is provided with seal ring, plastic washer, claw and push pipe from outside to inside successively; Push pipe length and annular groove are fitted mutually, its outer end and claw are inconsistent, and inner end is when screwing and the annular groove pig.

Above-mentioned a kind of pipeline quick union is provided with seal ring between described rotation set and the push pipe.

Above-mentioned a kind of pipeline quick union, the free end that described claw extends internally is tapered.

Above-mentioned a kind of pipeline quick union, described rotation set is inner to be the hole enlargement rank, and screw thread is formed on the inboard wall in hole enlargement rank, and plastic washer, claw and push pipe inwardly set gradually along the hole enlargement rank.

Above-mentioned a kind of pipeline quick union, described push pipe outer end is connected with the inwall buckle of rotation set.

Above-mentioned a kind of pipeline quick union, described seal ring are the corrugated O RunddichtringO in cross section.

After the utility model adopted said structure, the internal thread of rotation set was corresponding with the outside thread of body end, and the be threaded annular groove of end of the push pipe length in the rotation set and body is right mutually; Through being screwed together between rotation set and the body, when push pipe with after the annular groove bottom contacts, the outer end and the claw of push pipe are inconsistent; When rotation set and body continue to be spirally connected; The reaction force of push pipe is given in the annular groove bottom, and push pipe is inwardly moved in rotation set, the claw of conflicting with push pipe is opened in pipe and blocks main pipe; Realize the seamless link of two pipe fittings, have easy for installation, quick detachable and advantage of simple structure; The seal ring of seal ring that between rotation set and push pipe, is provided with and rotation set inwall all is a silica gel material, and silica gel sheath has positional stability preferably, has better sealing.
