Description

Novel PE pipe fittings

Technical field

The utility model is related to a kind of conduit coupling more particularly to a kind of novel PE pipe fittings.

Background technology

Currently, unexpected fracture often occurs in use for PE pipes.Need replacing new pipeline after fracture, however this Kind processing mode cost is higher.

For this situation, technical staff can generally repair to be used after the fracture PE pipes displaced.It is existing to repair Compound method is to carry out cutting flat mouth by that will be broken connector, then docks two notch again, melts notch hardening after cooling It links together.However by the tube wall after bond vitrified in docking can outwardly convex, cause that bonding part is uneven, tube wall It extends out.

In engineering the drilling field, the outer casing of pipe need to be generally coordinated to use, the annular space between casing internal diameter and PE pipe outside diameters Receiving PE pipes are only sufficient to be inserted.Therefore, it can cause PE pipes that cannot be inserted into shield after being extended out at melting adhered PE pipe meltings It is used in cylinder.

Utility model content

Disadvantage in for the above-mentioned prior art and deficiency can be connected quickly the purpose of this utility model is to provide a kind of It is broken the connector of PE pipes.

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

A kind of novel PE pipe fittings, including junction block, expansion loop and nut, the junction block include intermediate tube and both ends loudspeaker Opening, the flare openings coordinate with PE ligaments；Nut is threadedly coupled with the intermediate tube of junction block, and expansion loop has set Cover for seat on intermediate tube and multiple tiles with flare openings cooperation；The nut resists cover for seat, is pushed away by rotating nut Dynamic cover for seat, and then tile is squeezed into the gap of PE pipes and flare openings, make to fasten between junction block and PE pipes by tile Connection.

Preferably, the end face of the nut towards cover for seat is provided with mandril, corresponding to add in the side of cover for seat towards nut Work has card slot；When nut is with respect to central tube precession, mandril resists card slot and expansion loop rotation is driven to advance.

Preferably, it is sealed by gasket between the junction block and expansion loop.

Preferably, the quantity of the tile is 3-8 pieces, and the tile, which circularizes, to be evenly distributed in cover for seat.

Preferably, the mandril is 3-6, and mandril is evenly distributed on nut.

Preferably, the tile of the expansion loop and cover for seat are integrated molding structure.

Preferably, it is carved with fine thread on the outer wall of the expansion loop.

Preferably, the inner wall of the tile is the inclined-plane coordinated with flare openings, and outer wall is plane.

Compared with prior art, the embodiment of the novel PE pipe fittings of the utility model has at least the following advantages：

The novel PE pipe fittings of the utility model link together the two of fracture section PE pipes from inside, connection it is simple and quick and Tube expansion will not occur, the PE pipes reconnected together are still inserted into using into casing.

Specific implementation mode

With reference to embodiment and its attached drawing, the utility model is described in further detail, and following embodiment is descriptive , it is not restrictive, protection scope of this utility model cannot be limited by this.

As shown in Figs. 1-5, a kind of novel PE pipe fittings, including junction block, expansion loop and nut 1, the junction block include Intermediate tube 8 and both ends loudspeaker opening, the flare openings 7 coordinate with PE ligaments；8 spiral shell of intermediate tube of nut 1 and junction block Line connects, and expansion loop has the cover for seat 5 being sleeved on intermediate tube 8 and the multiple tiles 4 coordinated with flare openings 7；The nut 1 Cover for seat 5 is resisted, cover for seat 5 is pushed by rotating nut 1, and then tile 4 is squeezed into the gap of PE pipes and flare openings 7, led to Crossing tile 4 makes to be fastenedly connected between junction block and PE pipes.

As shown in Figure 9 and Figure 10, the end face of the nut 1 towards cover for seat 5 is provided with mandril 2, corresponding in 5 direction of cover for seat The side of nut 1 is machined with card slot 3；When nut 1 is with respect to central tube precession, before mandril 2 resists the drive expansion loop rotation of card slot 3 Into.

It is sealed by gasket 6 between the junction block and expansion loop.

The quantity of the tile 4 is 3-8 pieces, and the tile 4, which circularizes, to be evenly distributed in cover for seat 5.

The mandril 2 is 3-6, and mandril 2 is evenly distributed on nut 1.

As Figure 6-Figure 8, the tile 4 of the expansion loop and cover for seat 5 are integrated molding structure.

It is carved with fine thread on the outer wall of the expansion loop.

The inner wall of the tile 4 is the inclined-plane coordinated with flare openings 7, and outer wall is plane.

By two fracture PE pipes be connected on this connector, rotate forward nut 1 respectively, when the mandril 2 that nut 1 protrudes above with it is swollen When the recessed card slot 3 of tensioner ring cover for seat 5 is coupled, nut 1, which will rotate forward, to drive expansion loop to rotate forward, and at the same time nut 1 will push swollen Tensioner ring moves forward；Since 8 diameter of junction block intermediate tube is small, 7 diameter of flare openings is gradually increased from inside to outside, and expansion is circumferential It will be expanded while preceding mobile；Again due to there is fine thread on 4 surface of expansion loop tile, expansion ring surface will be with PE inside pipe walls Threaded engagement occurs, to achieve the purpose that connect.

The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not It is confined to this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should Subject to the scope of protection of the claims.
