Gripping member includes casing and the fixing piece that connect with the end face of casing；Sealing element is placed in casing；One end of sealing element is equipped with and opens
Mouthful, the other end of sealing element is connect with fixing piece, and the side of sealing element is equipped with cricoid seal convexity, seal convexity and opening phase
To setting.
The pipe sleeve of the utility model is set in the outside of polyethylene pipe and is fixed, and fixing piece is in the end of polyethylene pipe
Face, sealing element are placed in the inside of polyethylene pipe.The seal convexity of sealing element is contacted with the inner surface of polyethylene pipe, and is played sealing and made
With.During the test, medium is full of in polyethylene pipe, and the pressure of medium gradually rises, the medium in opening
Pressure increases accordingly, and medium struts sealing element, and the contact between seal convexity and polyethylene pipe is even closer, makes seal convexity
Sealing effect between polyethylene pipe is more preferable, that is, realizes the high-pressure self-sealing of medium in managing, pressure is higher, and sealing effect is got over
It is good.
Further, above-mentioned opening is in horn-like, inside to the outside of sealing element of the sectional area self-sealing part of opening by
It is cumulative big.
The opening of the utility model is in horn-like, and medium is more easier to strut sealing element, and self-sealing effect is more preferable.
Further, the material of above-mentioned sealing element is rubber.
The sealing element of the utility model rubber material and the sealing effect of polyethylene pipe are preferable, and the sealing of rubber material
Part has certain deformability, is easy to be strutted by medium.
Further, the inside of above-mentioned casing is equipped with annular knurl.
Due to the typically no flange in the end of polyethylene pipe, screw thread etc., the mechanical connection between casing and polyethylene pipe is only
It can be frictional connection.The annular knurl being arranged on the inside of the casing of the utility model can increase the friction between casing and polyethylene pipe
Power keeps the connection between casing and polyethylene pipe stronger.
Further, the outer sheath of above-mentioned casing is equipped with clip, and clip is oppositely arranged with annular knurl.
The utility model, come squeezing bushing, increases the pressure between annular knurl and polyethylene pipe, Jin Erzeng by tightening clip
Friction between jacketed pipe and polyethylene pipe keeps the connection between casing and polyethylene pipe stronger.
Further, the breach quantity of above-mentioned clip is 1, and the indentation, there of clip is bolted.
The breach quantity of the utility model clip is 1, and the power that clip can be made to apply polyethylene pipe is in circumferential direction
Uniformly, increase the forced area of polyethylene pipe.
Further, it further includes press machine that above-mentioned polyvinyl piping materials, which examine equipment,.
The utility model has the following beneficial effects:
1, the sealing element of the utility model is equipped with opening, and when overpressure increases, high-pressure self-sealing may be implemented, improve
The sealing effect of sealing element.
2, integrally using mechanical connection, structure is simple and convenient to operate, connects reliably the utility model.

Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
Embodiment
Fig. 1 is please referred to, it includes press machine, polyethylene pipe 140 and plugging device 100 that polyvinyl piping materials, which examine equipment, is gathered
One end of ethylene tube 140 is connect with press machine, and the other end is connect with plugging device 100.
Plugging device 100 includes clamping piece 110 and sealing element 120.Clamping piece 110 includes casing 111 and fixing piece 112.
