Abstract

The invention discloses a novel method for tightly grasping pipe in pipe device. Traditional pipe device usually uses claw to hold the pipe, but the claw is made of plastic and is subject to fatigue during using, or the claw is made of metal and results in heavy damage to surface of pipe. The invention employs series of thorns which increases grasp area and do little harm to pipe surface; increased grasp area largely reduces the fatigue degree of plastic thorns.

Description

Intelligent locking pipe device

Technical field:

The present invention relates in general to tube equipment, but more specifically, relating to has two sections pipe to be connected to link together with the mode of liquid airproof, and does not need to adopt welding, and is bonding, other conventional arts of the pipeline of special tool(s) or extended immobilization.

Background technique

Plastic tube is used to carry liquid for a long time, water for example, chemical liquid and other any liquid. tube equipment is used to be connected the pipeline of mutual coupling. and these tube equipments must provide one in certain operating temperature, the interior connector without any the liquid airproof that leaks of the scope of pressure and a series of environmental conditionss.

The commodity that the tube equipment of many types has been arranged now, for example, compression system, the enlarging system, interspersed system and hot melt connect. and prevailing in the tube equipment is to utilize the pincers tooth to fix the compression system of pipeline. among the present invention, inner at the device body with a kind of method of a series of sour jujube as fixing tube, replacing this traditional pincers tooth. this a series of sour jujube is positioned at the inwall of grabbing ring, grabbing ring promptly is the place that sour jujube contacts with pipeline external surface. and the movement direction that the shape of sour jujube is designed to pipeline when pipeline is advanced in the device tilts. and this design prevents to advance in the course of action pipe surface is produced scratch or damage. in the time of after pipeline advances, will drawing back, this design can make that sour jujube clenches pipe surface. in this case, the hardness of sour jujube is far longer than pipe surface. therefore, the material that is selected as sour jujube depends on the type of pipeline. high density polyethylene (HDPE) pipeline for example, low density polyethylene (LDPE) (LDPE) pipeline, plastic pipes such as polybutylene pipeline have medium hardness. and need the bigger engineering plastics of hardness to make sour jujube.Polyvinyl chloride pipeline (PVC), polypropylene pipe (PP), atactic copolymerized polypropene pipelines such as (PPR) is to have the more plastic pipe of high hardness. sour jujube is designed to make with fine sand, husky size and sharp-pointed degree are determined by pipeline applications. and have the more pipeline of high hardness for those than aforementioned tube road, the sour jujube of being made by thin stainless steel sheets is installed to the inwall of tube equipment securely. and those stainless sour jujubes are enough to fix pipeline.

Fig. 5 is that a width of cloth shows the perspective view of grabbing ring that is complementary with dissimilar sour jujubes.

Embodiment

The basic element of character of the tube equipment of described " intelligent locking " is by tube equipment body 1, and the sealing O shape ring 2 of elliptical shape is grabbed ring 3, protective cap 4

Described tube equipment body 1 has columnar shape, and a via 6 in described via 6, has retaining pipe device 7, and ring cavity 9 is grabbed in O shape chamber 8.

The O shape of described elliptical shape ring 2 is in O shape ring 8. and the sealing O shapes ring 2 of described O shape ring 8 restriction elliptical shapes is movable in default position ranges, and stops and grab the described sealing O shape of ring 3 compressings and encircle 2. therefore, does not need external force with in the pipeline 18 advancing means bodies 1.

The described ring 9 of grabbing has cone shape, and the inner wall surface that enters into tube equipment is outwards opened in its lower end. and described shoulder 10 of grabbing ring cavity 9 when touching the shoulder 12 of grabbing ring 3, stops the activity of grabbing ring 3.

The described ring module 3 of grabbing is positioned at and grabs ring cavity 9. and the described ring module 3 of grabbing has the aperture lines that the compression movement of ring module 3 is grabbed in cone shape and promotion. and the top column part of grabbing ring module 4 has many indentations, described indentation is divided into big and small wall with the top column part. at the top of little wall, the parts 13 at described little angle extend out impel grab ring module 3 central shaft can and the central shaft of pipeline 18 and tube equipment body 1 aim at. a series of sour jujubes are distributed in and grab the internal surface that encircles 3 lower end.

When an end chamfering of pipeline 17 and be inserted in the tube equipment body 1, grabbing ring 3 expansions makes described pipeline pass through. during pipeline moves inward, the sour jujube of described series will can not destroyed pipe surface, because being configured to the direction that moves to described pipeline, they tilt. then, pipeline 17 process ovaloid seal O shape rings 2 also stop on the described retaining pipe device 7. when described pipeline 17 inside produce pressure, described pipeline 17 is removed from described retaining pipe device 7. simultaneously, the described ring 3 of grabbing is retracted along described pipeline 17. described draw back to decompose make the described ring 3 of grabbing move to the inclined surface that ring cavity 9 is grabbed in described taper. move along described inclined surface along with grabbing ring 3, described ring 3 outer surface and the pressure that are pressed in described pipeline 18 of grabbing constantly increase, and a series of sour jujubes are engaged in the outer surface of pipeline 18 dearly.The described ring 3 of grabbing is attached to tightly on the described pipeline 18 not that offset returns, and touches described shoulder 10. of grabbing ring cavity 9 then up to described shoulder 12 of grabbing ring 3, describedly grabs ring 3 and 18 stop motions of described pipeline.

Use a kind of key 18 of particular design, described pipeline 17 is removed from described tube equipment 1 easily. by making described aperture lines 11 separately toward described 11 li wedge 19. described wedges 19 that insert described keys 18 of aperture lines of grabbing ring module 3. this action will make the described ring module 3 of grabbing outwards expand along radial direction. therefore described described expansion of grabbing ring module 3 extracts the sour jujube of described series out from the surface of described pipeline 17, and pipeline 17 can easily be extracted out from tube equipment 1.

Having shown 3 types sour jujube among Fig. 5. each type is applicable to one type pipeline. and the sour jujube 14 made from hard engineering plastics is used for medium-hard pipeline for example HDPE pipeline and LDPE pipeline. and the pipeline that the sour jujube made from sharp-pointed fine sand 15 is used for high hardness more is pvc pipe road and PP pipeline for example. and the pipeline that the sour jujube made from stainless steel sheets 16 is used for maximum hardness is steel pipeline for example.
