Description
Technical Field
The utility model relates to a pipeline butt joint device, in particular to a PE pipeline quick butt joint assembly.
Background
The PE plastic pipeline is widely applied to industrial production due to the advantages of corrosion resistance, small resistance, convenience in laying and the like. In use, butt joint of plastic pipelines is a technical problem because the plastic pipelines cannot be welded like steel pipes.
In the conventional technology, a quick connector is usually connected for butt joint. The following disadvantages exist in the process of using the quick connector:
1. is easy to be broken. Generally, night patrol of continuous production enterprises is less, the continuous stability of production is influenced by the fact that a pipeline is broken, and particularly, a pipeline used for conveying acid-base liquid is easy to cause casualties and environmental pollution after being broken, so that potential safety hazards exist.
2. The butt joint is not easy. When the quick connector is used, two sides of the quick connector are required to be respectively bound and connected with the plastic pipeline, and the plastic pipeline is hard and is not suitable to be bound due to small friction of the inner wall.
3. The price is high. Quick connectors are expensive and not suitable for long-term delivery of acidic and basic liquids.
The mode of "steel pipe short circuit" connection plastic line still adopts among the prior art, the drawback of "steel pipe short circuit" connected mode:
1. the resistance increases, affecting the delivery performance of the pump. In the process of conveying media in the pipeline, when the media flow through the middle joint steel pipe, the flow form is changed from laminar flow to turbulent flow, and the resistance is increased.
2. The connection is difficult. Because the plastic pipeline is hard, the inner wall has small friction and is difficult to directly bind, and the plastic pipeline is easy to break.
Therefore, it is urgently needed to research a rapid butt joint device for PE pipelines, which is easy for butt joint operation of the pipelines, has more firm and stable butt joint position of the pipelines, small influence on conveying resistance and low cost, and is suitable for conveying acid-base liquid for a long time.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art, and provides a PE pipeline quick butt joint assembly which is easy for pipeline butt joint operation, more firm and stable in pipeline butt joint position, small in influence on conveying resistance, low in cost and suitable for conveying acid and alkali liquid for a long time.
The utility model is realized by the following technical scheme: the utility model provides a quick butt joint subassembly of PE material pipeline, includes mould base and moulding centrum, the upper end middle part of mould base is provided with circular shape recess down, the centre department of mould base recess down is provided with central through-hole, the fixed centrum screw rod that is provided with in bottom center of moulding centrum, the bottom of moulding centrum is located in the recess down, the centrum screw rod passes central through-hole is connected with a nut, the lateral wall of recess down with form flange shaping clearance between the bottom lateral wall of moulding centrum.
The pipe fitting butt joint device further comprises two butt joint flange plates used for connecting the pipe fittings, and a locking bolt and a locking nut used for connecting the two butt joint flange plates.
The shaping vertebral body is in a frustum shape with the diameter gradually increasing from top to bottom.
The mould base, the moulding centrum is aluminium matter structure.
The mould base moulding centrum is the iron structure spare.
The utility model has the beneficial effects that: the utility model is convenient to use, easy to butt joint the pipelines, more firm and stable in the butt joint position of the pipelines, small in influence on conveying resistance, low in cost and suitable for conveying the acid-base liquid for a long time.

Detailed Description
The present invention is described in detail below with reference to the attached drawings.
As shown in fig. 1 and 3, a fast butt joint assembly for a PE pipeline 8 comprises a mold base 1 and a shaping cone 4, wherein a circular lower concave portion 2 is arranged in the middle of the upper end of the mold base 1, a central through hole 3 is arranged at the center of the lower concave portion 2 of the mold base 1, a cone screw 5 is fixedly arranged at the center of the bottom of the shaping cone 4, the bottom end of the shaping cone 4 is located in the lower concave portion 2, the cone screw 5 penetrates through the central through hole 3 to be connected with a nut 6, and a flange forming gap 7 is formed between the side wall of the lower concave portion 2 and the side wall of the bottom end of the shaping cone 4.
As shown in fig. 2, the pipe fitting joint structure further comprises two butt flange plates 9 for connecting the pipe fittings, and a locking bolt 10 and a locking nut 11 for connecting the two butt flange plates 9.
During operation, a shaping cone 4 is placed in the lower concave part 2 of the mold base 1, and a cone screw 5 penetrates through the central through hole 3 of the mold base 1 and is locked and fixed by a nut 6. The PE material pipeline 8 is heated to be softened, then the softened end of the PE material pipeline 8 is sleeved on the shaping centrum 4, and the PE material pipeline 8 is pressed downwards, so that the softened end of the PE material pipeline 8 moves downwards along the shaping centrum 4 to enter the flange forming gap 7, and a flange 12 is formed. And taking down the PE pipeline 8 from the shaping vertebral body 4 for later use. The same method is adopted to process the other section of PE pipeline 8 into the flange 12, the flanges 12 of the PE pipelines 8 at two ends are opposite to each other, and the two butt flange plates 9 are compacted and connected and locked through the locking bolt 10 and the locking nut 11. The flanges 12 of the two sections of PE pipelines 8 are compressed by the two butt flange plates 9 and are in sealed butt joint with each other, the butt joint positions of the pipelines are firmer and more stable, the influence on conveying resistance is small, the cost is low, and the device is suitable for conveying acid and alkali liquid for a long time.
Referring to fig. 1, the shaped vertebral body 4 is in the shape of a frustum with a gradually increasing diameter from top to bottom. The cone molds with different diameters are arranged aiming at pipelines with different pipe diameters. The mold base 1 and the shaping cone 4 are both aluminum structural members, and of course, can also be iron structural members. The utility model can be repeatedly used, has low cost, and is also suitable for the quick butt joint of plastic pipelines made of other materials.
Finally, it should be noted that the above-mentioned contents are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, and that the simple modifications or equivalent substitutions of the technical solutions of the present invention by those of ordinary skill in the art can be made without departing from the spirit and scope of the technical solutions of the present invention.
