Description

A kind of PE pipe connections

Technical field

It the utility model is related to PE pipe interconnection techniques field, more particularly to a kind of PE pipe connections.

Background technology

PE is vinyon, and PE pipes are a kind of tubing made of vinyon, its with it is anticorrosive, light-weight, The characteristic such as easy processing, moisture-proof, but according to the difference of length, it is necessary to be attached to PE pipes in construction, but traditional PE Pipe connects the shortcomings of relatively slow there is connection speed and insecure, easy leakage, to be filled for this reason, we have proposed a kind of connection of PE pipes Put.

Utility model content

The purpose of this utility model is and a kind of PE pipes connection dress proposed in order to solve shortcoming existing in the prior art Put.

To achieve these goals, the utility model employs following technical solution：

A kind of PE pipe connections, including connection ring are designed, the connection ring both sides are connected to casing, the connection Ring both sides are additionally provided with internal lining pipe, and the internal lining pipe is located in casing, and the internal lining pipe is coaxially disposed with casing, the internal lining pipe Outer surface offers thread respectively with internal surface of casing, and PE pipes, institute are clamped with the gap between the internal lining pipe and casing To state liner pipe internal surface and offer to be equipped with grooves on two sides and groove and strengthen keel, described sleeve pipe outer surface is arranged with garter spring, and The garter spring both ends are connected with compact heap, and two through holes are offered on the compact heap, and are connected between the compact heap tight Fixing bolt.

Preferably, the thread of the connection ring side is in left-handed state, and the thread of the connection ring opposite side is in Dextrorotation state.

Preferably, the one end of the internal lining pipe away from connection ring is equipped with drop balk ring.

Preferably, the connection ring internal diameter is equal with the internal diameter of internal lining pipe, and the connection ring outside diameter is more than the outer of casing Footpath.

Preferably, the connection ring outer ring surface offers some grooves.

The utility model proposes a kind of PE pipe connections, beneficial effect is：In the present solution, pass through casing, liner Pipe is clamped and connected the PE pipes to be connected, and thread is additionally provided with the surface between casing, internal lining pipe, and outside of sleeve is set There is garter spring so that connection is more firm, and is not easy to reveal, and has also speeded up connection speed, and using simple, convenient.

Brief description of the drawings

Fig. 1 be the utility model proposes a kind of PE pipe connections schematic cross-sectional view；

Fig. 2 be the utility model proposes a kind of PE pipe connections overlooking the structure diagram.

In figure：Connection ring 1, casing 2, internal lining pipe 3, strengthen keel 4, be thread 5, drop balk ring 6, garter spring 7, compact heap 8, tight Fixing bolt 9, groove 10, PE pipes 11.

Embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

With reference to Fig. 1-2, a kind of PE pipe connections, including connection ring 1,1 both sides of connection ring are connected to casing 2, even Connect 1 both sides of ring and be additionally provided with internal lining pipe 3, internal lining pipe 3 is located in casing 2, and internal lining pipe 3 is coaxially disposed with casing 2, in connection ring 1 Footpath is equal with the internal diameter of internal lining pipe 3, and 1 outside diameter of connection ring is more than the outside diameter of casing 2, and 1 outer ring surface of connection ring offers some recessed Groove 10,3 outer surface of internal lining pipe offer thread 5 respectively with 2 inner surface of casing, the gap inner clip between internal lining pipe 3 and casing 2 Hold PE pipes 11 so that preferably connected between PE pipes, will not cause to reveal or breathe freely, good airproof performance, and groove 10 It can be used to be inserted into extension bar in connection so that connection more convenient quickly.

The thread 5 of 1 side of connection ring is in left-handed state, and the thread 5 of 1 opposite side of connection ring is in dextrorotation state, interior The one end of bushing pipe 3 away from connection ring 1 be equipped with drop balk ring 6, be rotatablely connected ring 1 when, thread bite PE pipe surfaces, increase liner Frictional force between pipe 3, casing 2 and PE pipes so that connection is more firm, and adds the compactness of connection, and drop balk ring 6 drops The low resistance of Bottomhole pressure liquid, is conducive to the material that PE pipelines carry out transport flow.

3 inner surface of internal lining pipe, which offers to be equipped with grooves on two sides and groove, strengthens keel 4, and 2 outer surface of casing is arranged with hoop Ring 7, and 7 both ends of garter spring are connected with compact heap 8, two through holes are offered on compact heap 8, and fastening is connected between compact heap 8 Bolt 9, keel 4 and garter spring 7 add the firmness and intensity between PE pipe connections and PE pipes again.

The above, is only the preferable embodiment of the utility model, but the scope of protection of the utility model is not This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality New technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
