Description
Technical field
The technical field of nonmetal pipeline is the utility model is related to, is led more particularly to the technology of GRP pipe
Domain.
Background technology
GRP pipe is that one kind is formed by glass fiber winding, and through nonmetal pipeline made from infrared curing, it has
There are the corrosion such as insulation, acid-proof, alkali, salt, antistatic, the features such as non-corrosive is non-aging, nontoxic, and the elasticity of flexure is good, and install
It is very easy, construction period is substantially shorter, operating expenses is reduced, is widely used in the industries such as oil, chemical industry and draining.So
And there are some following shortcoming for GRP pipe common at present：First, rigidity is poor, structural strength is not ten sub-arguments
Think, under mechanical stress effect, the phenomenon that easily deforms and rupture；Second, the company of current common heavy-caliber fiber reinforced plastic pipe
Double O-ring sealing socket joint connections are usually used in the mode of connecing, but use this connection mode, and the sealing performance of junction is not
It is very good, when differential settlement occurs for adjacent channel or after long-time service, sealing performance decline is easy to cause, is revealed
Phenomenon.
Utility model content
The purpose of this utility model is exactly that a kind of structural strength height, ability of anti-deformation are provided to solve above-mentioned deficiency
By force, and with performance is tightly connected well, the high-strength light GRP pipe of leakage can be effectively prevented.
In order to solve the above-mentioned technical problem technical solution that the utility model uses is as follows：
A kind of high-strength light GRP pipe, it is mainly made of tube body, the first sealing ring and the second sealing ring, the pipe
The tube wall of body is made of resin-lined layer, metal shielding, glass fiber winding layer and resin protective layer successively from the inside to the outside, institute
The one end for stating tube body is provided with plug, and the other end of tube body, which is provided with, takes the lead, and first is offered on the lateral wall of plug
Closure gasket groove, offers annular slot in the end taken the lead, the second sealing ring is offered on the madial wall for annular slot of taking the lead
Groove, first sealing ring are nested with the second closure gasket groove, and second sealing ring is nested with the first closure gasket groove.
First closure gasket groove and the second closure gasket groove are paired respectively to be arranged, first sealing ring and the second sealing ring
It is rubber O-ring seal.
The utility model is using the attainable beneficial effect of above-mentioned technical solution institute：By resin-lined layer with
Metal shielding is set between glass fiber winding layer, so as to significantly improve the structural strength and ability of anti-deformation of tube body, is had
Effect extends the service life of tube body.The plug of a piece pipeline is caught in by this high-strength light GRP pipe when being attached
In the annular slot that another pipeline is taken the lead, and sealed by the first sealing ring and the second sealing ring, by plug with taking the lead
Clamping seals, and forms sealing interlocking connection, so as to substantially increase sealed connection intensity, effectively prevent the hair of leakage phenomenon
It is raw.

Fig. 2 is the structure diagram after the utility model connection；
Fig. 3 is the partial structural diagram at A in Fig. 2.
Embodiment
As shown in Figure 1, a kind of high-strength light GRP pipe, it is mainly by tube body 1, the first sealing ring 2 and the second sealing
Ring 3 is formed, and the tube wall of the tube body 1 is from the inside to the outside successively by resin-lined layer 4, metal shielding 5, glass fiber winding layer 6
Formed with resin protective layer 7, stainless steel can be selected in the metal shielding 5.The one end of the tube body 1 is provided with plug
9, the other end of tube body 1, which is provided with, takes the lead 10, and the first paired closure gasket groove 12 is offered on the lateral wall of plug 9,
Take the lead 10 end offers annular slot 13, and the second paired sealing is offered on the madial wall for taking the lead 10 annular slots 13
Annular groove 14, first sealing ring 2 are nested with the second closure gasket groove 14 respectively, and second sealing ring 3 is nested with respectively
In one closure gasket groove 12.Rubber O-ring seal common on the market can be selected in first sealing ring, 2 and second sealing ring 3.By
Shown in Fig. 2 and Fig. 3, when two high-strength light GRP pipes are being attached, the plug 9a of first pipeline is caught in
Two pipelines take the lead 10b annular slot 13b in, formed sealing interlocking connection.It should be noted that for the ease of observation, it is attached
Hatching in figure is removed.
Claims (2)
- A kind of 1. high-strength light GRP pipe, it is characterised in that：It is mainly by tube body, the first sealing ring and the second sealing ring structure Into the tube wall of the tube body is protected by resin-lined layer, metal shielding, glass fiber winding layer and resin successively from the inside to the outside Layer is formed, and the one end of the tube body is provided with plug, and the other end of tube body, which is provided with, takes the lead, and is opened on the lateral wall of plug Equipped with the first closure gasket groove, annular slot is offered in the end taken the lead, is offered on the madial wall for annular slot of taking the lead Two closure gasket grooves, first sealing ring are nested with the second closure gasket groove, and second sealing ring is nested with the first sealing ring In groove.
