Abstract

A gas pipeline joint is used for a joint connected between a gas joint and an automatic cutting device and is formed by buckling an upper block and a lower block. The cross section is a hexagonal long strip, the middle is provided with a colloid connecting pipe, the outside of the pipe is tightly clamped by a special-shaped torsion spring, the gas pipe can be conveniently inserted into the stepped connecting buckle of the gas joint and the automatic cutting device, the operation is simple, the labor and the time are saved, the appearance is attractive, and the connection quality is reliable.

Description

Joint of gas pipeline

A kind of gaspipe line joint is the pipe joint that pipeline connects fast between coal gas joint and the automatic cut off device.

Use at present at the coal gas joint and cut off connection between the pipeline automatically, the general employing on the powerful stepped shaft interface cylindrical that inserts the coal gas joint and cut off automatically of rubber pipe, prick with the steel wire watchman's wooden clapper again, with Drop-proof and leakage gas, this connection way is time-consuming, not attractive in appearance, and can be unreliable on quality of connection, vary with each individual.

The purpose of this utility model provides a kind of gaspipe line joint, is used for connecting coal gas joint and coal gas electrotome, and it can insert ladder quickly and easily and connect the button mouth, tightens the deficiency that overcomes prior art with special-shaped torsion spring.

The utility model is realized in the following way, this pipe joint is the microscler condition of inequilateral hexagonal section, it constitutes with following piece fastening by last piece, there is a flanged colloid connecting tube in two ends the centre, card has two special-shaped torsion springs on the connecting tube outer rim, the torsion spring head exposes outside the torsional spring slot of following piece bottom, and the counterbore of an interior hexagonal form is arranged in pipe joint one end in the heart, has two symmetries can prevent the rectangular block of rotating on the other end on the piece.

This model utility has following advantage, has avoided when using this pipe joint to connect the coal gas joint with automatic cut off device and must be connected simply rapidly with its saving of work and time of defectives such as artificial metal binding wire, and the beautiful shape quality of connection is reliable.

Accompanying drawing and drawing explanation:

Accompanying drawing 1 is a kind of gaspipe line joint decomposition chart

Accompanying drawing 2 is a kind of gaspipe line joint connection diagram

Piece, 2 times pieces, 3 connecting tubes, 4 special-shaped torsion springs, 5 joints, 6 electrotomes, 7 boss, 8 counterbores, 9 special-shaped torsion spring heads, 10 dowels, 11 positioning holes, 12 torsional spring slots, 13 rectangular block, 14 stepped shafts connect button on 1.

In conjunction with the accompanying drawings a kind of gaspipe line joint of the utility model is described further below by embodiment:

This joint make by last piece 1, piece 2 buttons and forming down, its cross section is an inequilateral hexagon long strips body, the tubulose connecting tube 3 that a two ends flanged pin is made by rubber is adorned in the centre, connecting tube outer through on snap in two special-shaped torsion springs 4, two heads 9 of torsion spring expose in torsion spring slotted eye 12 outer ends of piece 2 down.When fastening, last piece and following piece locate by 4 bands dowel 10 and positioning hole 11 slightly, on the end face of pipe joint, be shaped on the counterbore 8 of an interior hexagonal form, be shaped on two symmetries on the other end on the piece 2 and may be stuck in the rectangular block 13 that prevents to rotate on the boss 7 of coal gas joint 5.Installing and using as shown in Figure 2 of this pipe joint, an end of its band block are plugged on stepped shaft on the coal gas joint 5 and connect and smash, and two rectangular block 13 are stuck in the two ends of boss 7, and the other end inserts in the stepped shaft interface on the electrotome 6.

Claims

1, a kind of gaspipe line joint, it is characterized in that, profile is the inequilateral hexagon, the long strips body in cross section, it is fastened by last piece (1) and following piece (2) has the flanged colloid connecting tubes in two ends (3) in the middle of forming, card has two special-shaped torsion springs (4) on the connecting tube outer rim, abnormity torsion spring head (9) exposes outside following piece (3) bottom torsional spring slot (12), the counterbore (8) that an interior hexagonal form is arranged in pipe joint one end in the heart has two symmetries can prevent the block (13) that rotates on the piece on the other end (2).
