Abstract

The utility model discloses a crimping type screwed PTP pipe fitting, comprising a core pipe and an outer coat, wherein the core pipe comprises pipe bodies and connection heads which respectively paired left and right and the connection heads are inserted and connected with each other; also comprising a ferrule arranged on the outer wall of the connection head and screwed with one connection head and fastened with another connection head. The pipe fitting is tightly and firmly connected to facilitate disassembly, exchange or repeated usage and simultaneously the stability and reliability of the pipe connection is increased.

Description

A kind of fastening-pressing type RTP pipe pipe fitting that is threaded
Technical field
The utility model relates to pipeline interconnection technique field, relates in particular to a kind of fastening-pressing type RTP pipe pipe fitting that is threaded.
Background technique
Strengthen thermoplastic composite tube (RTP, Reinforced Thermoplastic Pipes) and mainly constitute usually by three layers, promptly inside and outside plastic layer and be arranged in the middle of the enhancement layer that is composited by reinforcing material.At present, for strengthening thermoplastic composite tube, adopt usually between the tube and tube to strengthen electric smelting sleeve or the connection of fastening-pressing type pipe fitting.
Prior art fastening-pressing type pipe fitting is made of core pipe and overcoat as a kind of connected element.During connection, the end of connected pipe is inserted in the gap between core pipe and the overcoat, tightens by implementing buckle press, and the connection between core pipe and the overcoat then is that both end is fixed together.Present this class pipe fitting of prior art, ubiquity complex structure between the pipe fitting, it is insecure to connect, get loose easily, sealing is poor, can not dismantle defective such as repeated use.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of fastening-pressing type rational in infrastructure, that be connected firmly RTP pipe pipe fitting that is threaded is provided, to improve steadiness and the reliability that pipeline connects, realize the repeated use of pipe fitting simultaneously, with the expense of reducing cost.
The purpose of this utility model is achieved by the following technical programs:
A kind of fastening-pressing type that the utility model provides RTP pipe pipe fitting that is threaded comprises core pipe and overcoat; Described core pipe comprises body and connecting head, and about pairing, insert embedding by described connecting head and connect and compose; In addition, also comprise lasso, described lasso is arranged on the outer wall of described connecting head, and is threaded with one of them connecting head, is buckle with another connecting head and is connected.The utility model is connected firmly the core pipe part by lasso, and has improved axially mounting power, is convenient to dismounting and change or repeated use simultaneously.
The utility model can be taked following further measure: described core pipe also comprises the collar, and the described collar is fixed in the junction of body and connecting head and is positioned at the termination that is connected tubing, which is provided with annular groove; The termination of described overcoat is provided with bulge loop, and this bulge loop can insert in the annular groove of the described collar.Like this, be convenient to the installation and removal of overcoat, also further improved the axially mounting power of pipe fitting simultaneously.
Be the installation of firm overcoat, the bulge loop of overcoat described in the utility model is connected in the annular groove of the described collar with concavo-convex clamping form through rotation.
The surface of contact that its left and right sides connecting head of core pipe described in the utility model is inserted the embedding connection is smooth curved surface, thereby helps closely cooperating.In addition, its axial length of the wall of described surface of contact is equal to or greater than pipe diameter, promptly, surface of contact between the connecting head has enough axial lengths to bear radial stress, make in the connection close and firm and be difficult for getting loose more of implementing to withhold between the core pipe connector of back, also improved radial support power simultaneously.
For improving the sealing that connects, the wall of surface of contact is provided with at least one seal ring between the core pipe connector described in the utility model.After implementing to withhold, seal ring is clamped on the wall between the connecting head, the seal ring difficult drop-off, and sealability is better and be not easy to lose efficacy.
The utlity model has following beneficial effect:
(1) rational in infrastructure between the pipe fitting, connection close and firm, and be convenient to dismounting and change or repeated use, flexible, and reduced cost.
(2) effectively improve axially mounting power and radial support power, improved the steadiness that pipeline connects.
(3) seal ring connects tight difficult drop-off, and sealability is better and be not easy inefficacy, has improved the reliability that pipeline connects.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model embodiment's a structural representation.
Among the figure: core pipe 1, left body 1a, left connecting head 1b, right body 1a ', right connecting head 1b ', surface of contact 1c, overcoat 2, bulge loop 2a, the collar 3, lasso 4, seal ring 5, tubing 6
Embodiment
Figure 1 shows that embodiment of the present utility model, comprise core pipe 1, overcoat 2, the collar 3 and lasso 4.
Wherein, core pipe 1 has body and connecting head, and about pairing, insert embedding by connecting head and connect and compose.The outer surface of left side body 1a, right body 1a ' has unidirectional tooth; The surface of contact 1c that left side connecting head 1b, right connecting head 1b ' insert the embedding connection is smooth curved surface, and the wall of surface of contact 1c has enough axial lengths to bear radial stress.On this wall, be set side by side with two O RunddichtringOs 5.
As shown in Figure 1, the collar 3 is fixed in the junction of body and connecting head and is positioned at the termination (collar 3 also can be one with core pipe 1) that is connected tubing 6.The collar 3 is provided with annular groove.
The internal surface of overcoat 2 has unidirectional tooth.The termination of overcoat 2 is provided with bulge loop 2a.Corresponding projection/the recess that is evenly equipped with on overcoat bulge loop 2a and the collar 3 annular grooves.The bulge loop 2a of overcoat can corresponding insert in the annular groove of the collar 3, can concavo-convex clamping form by rotating a certain angle just, and overcoat 2 and core pipe 1 are snapped together effectively reliably.
Lasso 4 is arranged on the outer wall of core pipe connector 1b, 1b ', and is threaded with one of them connecting head, is buckle with another connecting head and is connected.
When connecting tubing, the termination of tubing 6 is packed between the body and overcoat 2 of core pipe 1, install with the special erection unit that clamps pipe fitting, the card pressure of a locking of this clamping force formation tubing makes whole system can bear axial load and prevents to get loose, simultaneously also can clamp seal ring 5, make that sealability is better and be not easy to come off and lost efficacy. Core pipe connector 1b, 1b ' put lasso 4 outward again, and this lasso 4 is threaded with right connecting head 1b ', is buckle with left connecting head 1b and is connected, thereby left and right sides two-part of core pipe 1 are linked together effectively reliably.
