Abstract
The utility model relates to a pipe connecting piece, in particular to a polyethylene composite pipe connecting piece used in coal industry, and solves the problems of the prior connecting mode such as complicated operation, low work efficiency of workers and difficult disassembly. The connecting piece comprises the circular seal rings arranged at the connecting end faces of two polyethylene composite pipes and a connecting body arranged at a pipe joint, wherein the seal ring is wrapped inside the connecting body; the connecting body consists of two semicircular metal casings respectively clamped at both sides of a pipe; the outer edge of each semicircular metal casing is provided with a bolt hole and is respectively fixed by a bolt and a nut; moreover, the part of the internal wall of each semicircular metal casing contacting the pipe is tooth-shaped. With a simple structure, simple connecting mode, convenient assembly and disassembly, the utility model improves the labor efficiency of workers and has stable and reliable performances, good seal effect and strong pressure-bearing capacity; moreover, the utility model which meets the requirements of explosion protection in an underground mine is particularly suitable for the connection between polyethylene composite pipes which are formed into a steel mesh framework in an underground mine.
Description
Technical field
The utility model relates to a kind of pipe joint, is specially a kind of polyethylene compound pipe pipe connecting that is used for coal industry.
Background technique
At present, the polyethylene compound pipe road of gas extraction pipe, high-pressure air hose, high pressure supplying drainage connects the connection of most of employing steel pipe flange under the domestic coal industry mine, the holder of polyethylene pipe hot melt flange adds modes such as steel flange connection, fiber reinforced plastic pipe connection, these Placements exist sealing effect relatively poor in actual use, do not meet the downhole anti-explosion requirement, and attended operation is loaded down with trivial details, labor strength is high, inefficiency, and not easy to assemble, waste time and energy.
Summary of the invention
The utility model is in order to solve existing polyethylene compound pipe road Placement complex operation, labor strength height, inefficiency, and it is not easy to assemble, problem such as waste time and energy provides a kind of polyethylene compound pipe pipe connecting, has advantages such as easy to connect, quick, reliable.
The utility model is to adopt following technological scheme to realize: the polyethylene compound pipe pipe connecting, comprise that being arranged on two polyethylene compound pipe roads connects the circular seal ring of end face and the connecting body that is arranged on pipeline junction, seal ring is wrapped in the connecting body, described connecting body is made of two semicircle metal shells that fix respectively in the pipeline both sides, on two semicircle metal shell outer rims bolt hole is set and fixes by bolt, nut.Semicircle metal shell described in the utility model adopts a cast molding of metallic material, and the dimensioned amount is few, can satisfy the requirement of pipe fitting pressure; Described seal ring can form triple seal, and sealing principle forms the sealing of first road for the elasticity by seal ring when static state; After pipe fitting was installed, seal ring was subjected to the restriction of seal groove inner space in the semicircle metal shell, passively further compressed pipeline and formed the sealing of second road; When being full of medium in the pipeline, medium enters in the interior seal groove of semicircle metal shell, reacts on the sealing lip of seal ring, increased the power that is adjacent to of sealing lip and pipeline more, thereby reach the 3rd road reaction equation sealing, the pressure of pipeline inner fluid is big more, and the sealing of pipe fitting is good more; Described bolt adopts advanced technologies to make, screw bolt and nut all be up to state standards the regulation more than 8 grades, simultaneously the rate elongation of bolt has also been done corresponding optimization restriction, after feasible the installation, press when increasing in the pipeline, pipe fitting does not have open possibility, thereby guaranteed the stability of sealing, bolt structurally adopts the anti-form of revolving, only need one wrench got final product when making pipe fitting install, nut directly adopts flange surface nut, need not other shimming and gets final product locking nut, prevented that effectively the nut that vibrations cause from withdrawing from phenomenon, above-mentioned said bolt, nut is standard piece.
During concrete the connection, seal ring is placed in the middle of the pre-connection pipe ends face earlier, then two semicircle metal shells are fixed both sides at pipeline junction respectively, at last bolt is inserted in the bolt hole of semicircle metal shell outer rim, get final product with nut is fastening, convenient and fast connection, and can satisfy the requirement of explosion-proof, sealing and pressure-bearing.
The position of described two semicircle metal shell inwalls and tube contacts is the tooth shape, further makes connecting body and connected pipe fastening.
Compared with prior art, the utility model is simple in structure, Placement is simple and direct, easy accessibility, improved workman's efficiency, and it is stable and reliable for performance, good sealing effect, bearing capacity height, and applicable to requirement of explosion proof under the mine, the utility model are particularly useful for constituting under the coal mine connection between the polyethylene compound pipe road of steel wire mesh frame.

Among the figure: the semicircle metal shell 4-of 1-pipeline 2-seal ring 3-bolt hole
Embodiment
The polyethylene compound pipe pipe connecting, comprise that being arranged on two polyethylene compound pipe roads 1 connects the circular seal ring 2 of end face and the connecting body that is arranged on pipeline 1 joint, seal ring 2 is wrapped in the connecting body, seal ring 2 slightly larger in diameter are in pipeline 1 diameter, make sealing effect better, described connecting body is made of two semicircle metal shells 3 that fix respectively in pipeline 1 both sides, on two semicircle metal shell 3 outer rims bolt hole 4 is set and fixes by bolt, nut, the position that two semicircle metal shell 3 inwalls contact with pipeline 1 is the tooth shape.
During concrete the connection, earlier seal ring is placed in the middle of the pre-connection pipe ends face, then two semicircle metal shells are fixed both sides at pipeline junction respectively, at last bolt is inserted in the bolt hole of semicircle metal shell outer rim, get final product with nut is fastening.
