Abstract

The invention relates to a telescopic pipeline connector. The telescopic pipeline connector consists of a through body, sleeves, seal rings and a C-shaped snap ring; the through body is in a tubular hollow structure; grooves are formed in the outer wall of the through body at positions with the same distance from two ends respectively; the edges, close to the direction of the ends, of the grooves are straight angle-shaped; the edges far away from the direction of the ends is slope-shaped; the through body is integrally sleeved inside the two sleeves; the butted end of the two sleeves is provided with a baffle edge; two seal ring accommodating grooves are formed in each sleeve; the seal rings are arranged inside the seal ring accommodating grooves; the C-shaped snap ring is arranged between the inner wall of the sleeve and the outer wall of the through body at the position close to the baffle edge. The telescopic pipeline connector has the beneficial effects of being simple in mounting working procedures, convenient for operation, time-saving and labor-saving, reliable in sealing, and connection operation can be carried out under the working condition of pipelines.

Description

Telescopic Petrochemical Pipe Joints

Technical field

The present invention relates to a kind of assembling pipe joint, relate in particular to a kind of telescopic pipe connecting part.

Background technique

Pipe technology has practiced for many years, in every field, duct products and application are quite general both at home and abroad, as buried feedwater, draining blow-off line, water supply and sewerage pipeline for building, storm sewer etc., in these pipelines, often there will be various Pipeline damage accidents, is the engineering of a system to the maintenance of breakdown point, as buried pipeline, burying pipeline is underground, pipeline moves and changes inconvenience, and cannot dig on a wide area in the situation that, the movement of pipeline and replacing can be described as impossible, therefore, the difficult of connection again during pipeline rehabilitation, equally, many outdoor pipelines are for avoiding pipeline because of twisting, the situations such as bending cause pipeline damage, also tubing can be fixed by fixing devices such as pipe clamps, therefore as there is somewhere damage, use very difficulty of common accessory maintenance, and adopt special aftermarket attachment, if the patent No. is 201020157537.7 disclosed Rapid pipeline maintenance devices, its structure comprises the lock ring of C type, the two ends of lock ring are bolted, the inwall of lock ring is provided with rubber sealant, its advantage is in the situation that pipeline is not stopped work, to carry out pipeline maintenance, equally, as the industry, technician is known, as enough in this device width, can occur that breakdown point both sides pipeline is inserted in breakdown point in the situation that of not mobile at pipeline completely, then lock bolt is realized pipeline rehabilitation, but adopt this device maintenance pipeline existent defect, as the bolton instrument of needs special use, and the defect that bolt joint cannot seal, therefore this device is as assembling pipe joint or pipeline maintenance connection set implements cumbersome, even do not reach application target, the disclosed a kind of pipeline on-line maintenance device of patent 201020194084.4, solved the shortcoming that cannot seal of bolt joint, but it implements more loaded down with trivial details.

Summary of the invention

The object of this invention is to provide a kind of the deficiencies in the prior art that make up, convenient practicality, time saving and energy saving, sealing is reliable, the telescopic Petrochemical Pipe Joints that can carry out attended operation under pipeline working condition.

For achieving the above object, the present invention adopts following technological scheme:

Telescopic Petrochemical Pipe Joints, by straight-through body, sleeve, seal ring and C shape snap ring form, straight-through body is hollow tubular structure, on straight-through external wall, on the equidistant position of two-port, be respectively provided with a groove, groove limit near port direction is rectangular in shape, groove limit away from port direction is slope shape, straight-through body integral body is enclosed within two sleeves, the port of two docking sleeves is provided with rib, sleeve is provided with two seal ring standing grooves, seal ring is arranged in seal ring standing groove, C shape snap ring is arranged on the position of close rib between sleeve lining and straight-through external wall.

Beneficial effect of the present invention is: installation procedure is simple, and simple operation is time saving and energy saving, and sealing is reliable, can under pipeline working condition, carry out attended operation.

Accompanying drawing explanation

Fig. 1 is structure sectional view of the present invention;

Fig. 2 is the schematic diagram of placement location before connecting tube of the present invention;

Fig. 3 is the schematic diagram after connecting tube of the present invention completes.

Embodiment

As shown in Figure 1, telescopic Petrochemical Pipe Joints, by straight-through body 1, sleeve 2, seal ring 3 and C shape snap ring 4 form, straight-through body 1 is hollow tubular structure, on straight-through body 1 outer wall, on the equidistant position of two-port, be respectively provided with a groove 5, groove 5 limits near port direction are rectangular in shape, groove 5 limits away from port direction are slope shape, straight-through body 1 integral body is enclosed within two sleeves 2, the port of two sleeve 2 docking is provided with rib 6, sleeve 2 is provided with two seal ring standing grooves 7, seal ring 3 is arranged in seal ring standing groove 7, C shape snap ring 4 is arranged on the position of close rib 6 between sleeve 2 inwalls and straight-through body 1 outer wall.

As shown in Figure 2,3, utilize the step of connecting tube of the present invention to be: needs to be connected or damaged pipeline 8 to be repaired is cut into port spacing and just puts into telescopic Petrochemical Pipe Joints, then put into telescopic Petrochemical Pipe Joints, push sleeve 2 to pipeline 8 ports, make the seal ring 3 of sleeve 2 ports be inserted in pipeline 8 completely, complete pipeline and connect, for guaranteeing sealingly secure, suggestion is pushed into by sleeve 2 groove 5 that C shape snap ring 4 snaps on straight-through body 1 completely and is advisable.
