Description

Heavy caliber natural gas line is not depressured boring device

Technical field

The utility model relates to natural gas line fields more particularly to a kind of heavy caliber natural gas line not to be depressured aperture dress It sets.

Background technique

During natural gas line carries out fortune, because part needs to repair or piping foundation, need do not stopping the supple of gas or steam In the case of be not depressured aperture construction, need at this time pipeline external set up saddle holding card, to implement interim external pipe Circulation, to carry out pipeline replacement maintenance, traditional saddle holding card applies rubber mat at punching, and leakproofness is easy because of gas stream Dynamic to cause to reveal, leakproofness is not sufficiently good.

Utility model content

The utility model In view of the above shortcomings of the prior art, provides a kind of heavy caliber natural gas tube of good seal Road is not depressured boring device.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of heavy caliber natural gas line is not depressured lower armful of holding card on boring device, including saddle, seal gasket, saddle Card has No.1 half slot on the saddle inside holding card, have No.1 gluing slot on the inside of No.1 half slot, in No.1 gluing slot The symmetrical annular groove in portion, No.1 gluing slot top have No. two glued slots, and No. two glued slot internal symmetries are distributed bulge loop slot, institute Stating has cushion rubber inner hole inside seal gasket, seal gasket bottom has the convex pad in side, and the side top Tu Dian has flat rubber mat, flat rubber mat The symmetrical snap ring in top, flat rubber mat top have vertical rubber mat, found rubber mat outer symmetrical and are distributed bulge loop, flat rubber mat merging No.1 glue Glued in slot, snap ring and annular groove cooperation are closed, vertical rubber mat is placed in glued in No. two glued slots, bulge loop and the cooperation of bulge loop slot, saddle Upper holding card and seal gasket are glued.

Holding card outer symmetrical distribution No.1 connects protrusive board on the saddle, is uniformly distributed in No.1 inside No.1 connection protrusive board Hole, has No. two half slots under the saddle inside holding card, No. two half slots and No.1 half slot cooperatively form holding chamber, combustion gas Pipeline is placed in holding chamber, and holding card outer symmetrical is distributed No. two connection relief printing plates under saddle, is uniformly distributed inside No. two connection relief printing plates No. two inner holes, stud are inserted into No.1 inner hole and No. two inner holes, and stud both ends are spirally connected with nut, holding card and lower armful of saddle on saddle Card connection.

Holding card top has punching base on the saddle, has ring flange at the top of punching base, cushion rubber inner hole and punching base Inner hole forms venting cavity.

The utility model has the advantages that

Flat rubber mat outer symmetrical is distributed snap ring, and snap ring is placed in annular groove, founds rubber mat outer symmetrical and is distributed bulge loop, bulge loop is set Enter in bulge loop slot, the angle of snap ring and bulge loop holds vertical distribution, and can cooperate jointly makes leakproofness improve, gas pipeline merging two After in number half slot and No.1 half slot, pipeline external presses the convex pad in side, and deformation occurs, need to undergo when gas is scurried out the convex pad in side, Snap ring, bulge loop are three-layer sealed, make good seal, and reducing leakage may.
