Abstract
A quick first-aid repair joint applied to a PE pipeline. The main accessories are as follows: semicircular sleeve 1, bolt 2, salvage festival 3, sealing washer 4. The pipe joint is characterized in that the joint is formed by sleeving a semicircular sleeve with a split flange outside a pipeline to replace an original integral flange, so that the pipe is prevented from being pressed and deformed at the joint; processing barbs or grooves and other similar structures capable of increasing the axial telescopic friction force of the pipe on the inner wall of the semicircular sleeve, converting the axial telescopic motion of the pipe into radial telescopic motion, and preventing the pipe from falling off from the rush repair joint; when the sealing ring is used, the rush-repair joint is connected with the semicircular sleeve through the bolt, and the sealing ring is placed between the rush-repair joint and the semicircular sleeve and sleeved on the PE pipe to play a role in sealing. The utility model has the advantages of the tensile is pulled out, anticreep is broken away from, simple to operate is swift, joint strength is high, the leakproofness is good, durable, the small investment, the expense is low, economical and practical, and there is certain support and the effect of revising out-of-roundness to PE tubular product in the junction.
Description
Technical field
The utility model relates to a kind of pipe fittings in the chemical building material, and more particularly, the utility model relates to a kind of PE pipeline with rushing to repair joint.
Background technique
In recent years, PE (PE is that polythene material is called for short) pipeline development is rapid, and application quantity is increasing.But relatively lag behind with the supporting pipe fitting of PE pipeline and the knowledge experience of construction aspect.Aspect the quick repairing of PE feedwater piping, at present domestic also do not have a kind of effective connecting means, because the PE pipeline mainly connects by electric smelting or hot melt, and hot melt, electric smelting welding all need carry out under very dry condition.But when water supply line breaks down suddenly, even throttle down also is difficult to thoroughly water be stopped breaking in pipeline for the moment.Therefore the PE feedwater piping can not adopt the way repairing of hot melt, electric smelting, is only limited to the mechanical connection method that adopts.We consider the quick repairing joint of using PVC theoretically, but because the low characteristic of PE rigidity, the tubing out of roundness is bigger than PVC.Because little, the anti-adaptability to changes of Young's modulus of PE material is poor, the repairing joint structure that existing spheroidal graphite pipeline, pvc pipe road etc. use is inapplicable.The present domestic supporting pipe fitting that still do not have also has only molding and forming Φ 355 following pipe fittings abroad.Φ more than 355 in the heavy caliber pipe fitting also do not have at present, mainly be because shot capacity too big, equipment investment expense height, reasons such as formation of tubes difficulty in process.
Summary of the invention
The purpose of this utility model overcomes the deficiency in the quick reparation of present PE pipeline just; on the basis of ripe PVC repairing joint; carried out structure innovation according to the PE pipe characteristic; a kind of repairing joint that is applicable to that outdoor middle large-caliber water supply pipeline is used is provided; the repairing joint of this kind structure is easy to connect, in the joint PE pipe is had certain support protective action, has guaranteed the sealing of joint; the installation process simple and convenient can reach the repairing purpose very soon.
The purpose of this utility model is achieved by following technical solution.
A kind of novel middle heavy caliber PE pipeline is with rushing to repair joint, it is made up of semicircle sleeve 1, bolt 2, repairing joint 3 and seal ring 4, wherein, two semicircle sleeve 1 usefulness bolts connect into the sleeve of a full circle, be provided with flange at the one end, the two ends of described repairing joint 3 connect a sleeve with bolt respectively, are provided with seal ring 4 between the two.
Above-mentioned novel middle heavy caliber PE pipeline is with rushing to repair joint, and the inwall of described semicircle sleeve 1 is provided with hangnail or groove.
The utility model adopt this structure be because:
One, because water hammer and temperature produce axial tension to tubing, the utility model processes similar structure such as the hangnail that can increase tubing axial stretching frictional force or groove at sleeve lining, the tubing axial stretching is converted into radial expansion, thereby tubing can not be deviate from from the repairing joint, can play the effect of sealing all the time; Two, have the semicircle protection sleeve of split type flange plate at the outside suit of pipeline, replace original integral (type) flange dish, prevent that tubing is at the joint compressive deformation; Three, with reference to the size of pipe and tubing tolerance standard, work up the suitable dimension internal diameter, also can play correcting action to the out of roundness of PE tubing.The repairing joint is connected by bolt with the semicircle sleeve during application, and seal ring is placed in the middle of both and is enclosed within on the PE tubing, seals.
The utlity model has following advantage:
1. has the effect that prevents to break away from, resist drawing.
2. the repairing joint of this structure, the installation process simple and convenient can reach the repairing purpose very soon.
3. the join strength height has certain support and revises the out of roundness effect PE tubing in the joint.
4. guaranteed the sealing of joint, durable in use.
5. little investment, expense is low, and is economical and practical.
Description of drawings
Fig. 1 is for installing connection diagram (being painted with the pipeline of being rushed to repair among the figure);
Fig. 2 is a semicircle sleeve sectional view;
Fig. 3 is a semicircle sleeve left view.
Each label is among the figure: semicircle sleeve 1, bolt 2, repairing joint 3, seal ring 4, tubing 5.
Embodiment
Be described further below in conjunction with accompanying drawing.
When repairing is installed, the tubing 5 of at first sawed-off breakage spot, subsequently sawed-off tubing end is lifted respectively, bottom respectively puts into a semicircle sleeve 1, then put a seal ring 4, then two sawed-off tubing ends are inserted 3 butt joints of repairing joint, if damaged pipeline section is long, can be connected in series with a plurality of repairing joints, centering is put the semicircle sleeve 1 on tubing top well, hang up the bolt 2 of two semicircle sleeves, clamp PE tubing, hang up the bolt 2 of semicircle sleeve and repairing joint again, tighten one by one, tighten the bolt 2 of two semicircle sleeves at last, whole rapid pipe joint also can be used in the pvc pipe road.
