Abstract
The utility model discloses a pipeline joint for rush repairs use, which comprises a flange disc 5, adapter sleeve 2, and wedge-shaped seal ring 3, plain cushion 1 and bolt 4. An annular dummy club is arranged on the side of the compacted flange disc 5, the flange disc is arranged on both sides of the adapter sleeve 2, and a bevel edge ranging from 15 DEG to 40 DEG is in the end of the center bore. The utility model has the advantages of high strength, long service life, few excavation, easy installation, stability and reliability, and saving material.
Description
Technical field
The utility model relates to the pipe fittings in the chemical building material, and more particularly, the utility model relates to a kind of joint of plastic duct system.
Background technique
After breakage appearred in plastic pipe, restorative procedure commonly used was to stick with glue agent the sheet material identical with the plastic pipe material is bonded at breakage spot, with clamp or rope etc. sheet material and the former pipeline that is stained with is fixed together again at present.Or with the PVC welding gun weldering of the breakage spot of pipeline is lived, deficiency is only to be applicable in damaged repairings the such as pressure is lower and damaged scope is less local breach of pipeline or hole.For bearing the plastic pipe that pressure is higher or damaged degree is bigger, one segment pipe of its breakage can only be blocked, replace the pipeline of whole breakage with a new pipeline or the pipe fitting that has double-bellmouth that utilizes tubing to make, deficiency is need carry out a large amount of earth excavation engineerings just can finish repair.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes in the existing pipe rehabilitation technology, a kind of join strength height, long service life is provided, the earth excavation engineering work load is few, quick and easy for installation, reliable and stable and economical with materials, has been fit to the pipe coupling of repairing usefulness.
The purpose of this utility model is achieved by following technical solution.A kind of pipe coupling of rushing to repair usefulness, comprise supported flange dish, adapter sleeve, wedge-type seal circle, plain cushion, reach bolt, be shaped on annular boss on one end face of described supported flange dish, the two ends of described adapter sleeve are shaped on flange plate, at center hole one end one 15 °～40 ° chamferings are arranged.
Further, described wedge-type seal circle wedge angle is 15 °～40 °.
The utility model compared with prior art has following advantage.
1, join strength height, long service life;
2, the earth excavation engineering work load is few, quick and easy for installation;
3, reliable and stable and economical with materials.
Description of drawings
Accompanying drawing is a longitudinal sectional view of the present utility model, wherein
1, plain cushion 2, adapter sleeve 3, wedge-type seal circle 4, bolt 5, supported flange dish 6, pipeline
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Behind piping failure, the breakage spot that is embedded in underground pipeline 6 is excavated, and the pipeline section of breakage cut down, make pipeline 6 become two sections, distance was greater than the length of an adapter sleeve 2 between two sections terminations were faced mutually, two groups of supported flange dishes 5, wedge-type seal circle 3, adapter sleeve 2 are set to respectively on two segment pipes 6 that are repaired successively, add plain cushion 1 in the middle of two adapter sleeves 2, tight a bolt 4 then, move two adapter sleeves 2 again, the pipeline 6 at two ends is all inserted wherein, and the two ends pipeline 6 end faces chamfering of all crossing adapter sleeve 2.Respectively the supported flange dish 5 of adapter sleeve 2 both sides is tightened with corresponding adapter sleeve 2 usefulness bolts 4.The angle of the wedge shape of wedge-type seal circle 3 is identical with the chamfer angle of adapter sleeve 2 center holes, and wedge-type seal circle 3 is between the outer surface of the chamfer surface of the end face of supported flange dish 5 and annular boss, adapter sleeve 2 and pipeline 6.Wedge shape seal ring 3 produces distortion under the effect of bolt 4 impacting forces, squeezes firmly between adapter sleeve 2 and pipeline, thereby plays good seal action.
