Abstract
The utility model relates to a plastic pipe joint. A pipe is inserted in a groove of the joint, and the groove is formed from a joint pipe body and an aluminum alloy lantern ring sheathed out of the joint pipe body. An even clamping force is used on the outer part of the aluminum alloy lantern ring along the circumference, so that the pipe can be sealed. The utility model avoids the potential hazard of glue connection for the human body. Compared with other connection structures, the utility model has the advantages of simplicity, rapidness and low cost, and is a convenient, practical, safe and sanitary connection joint.
Description
The utility model belongs to the macromolecule member, is specifically related to the structure of plastic tube jointing.
Adopting polyethylene (PE), crosslinked polyethylene (PEX), polypropylene (PP), polybutylene (PB) and the plastic-aluminum combined tubing that waits is present emerging green tubing, carry liquid especially for water supply pipe with this class tubing, in energy-saving and environmental protection and application, has clear superiority, with it as a kind of desirable to mould for steel, China construction department widelys popularize, in the hope of progressively substituting Coating Steel Pipe.And the key that plastic tube is promoted the use of is to solve its interconnection technique, the main now several modes such as glue connection, metallic copper are threaded, hot melt connection that adopt on the China market.On construction process and manufacture cost, the chemical glue that uses during glue connects has certain toxicity, metallic copper be threaded processed complex, cost costliness, hot melt connects needs higher professional knowledge and expensive special device, owing to do not have easy, practical, reliable link, therefore seriously restricting popularizing of this type of tubing.
The purpose of this utility model is: design a kind of simple in structure, easy to use, reliable performance, beautiful shape, plastic tube joint that price is suitable, solve plastic tube field joint technical problem.
Technical solution of the present utility model is:
The jointing of less caliber tubing, mainly form by joint body, interpolation metal tube and the aluminum alloy collar, passive interpolation metal tube is positioned at the joint inboard wall of tube body, the aluminum alloy collar engages mutually by groove on it and flange on the joint body that to be positioned adaptor tube external, and have between the aluminum alloy collar and the external diameter joint body with the level one with the consistent groove of body section shape.
In the tubing insertion groove, with even clamping force, one group of projection clamp ring that joint body upper edge external diameter distributes embeds non-response distortion takes place in the tubing, tubing can be sealed to the aluminum alloy sleeve circulating application.
Provide accompanying drawing of the present utility model:
Fig. 1 is less caliber tubing of the utility model and jointing sectional arrangement drawing
Among the figure: 1 joint body, 2 interpolation metal tubes, the 3 aluminum alloy collars, 4 tubing, 5 protruding clamp rings, 6 flanges, 7 grooves, 8 grooves
Introduce implementation methods of the present utility model below in conjunction with accompanying drawing:
The jointing that is used for less caliber tubing is mainly by joint body 1, the interpolation metal tube 2 and the aluminum alloy collar 3 are formed, interpolation metal tube 2 is positioned at joint body 1 inwall, butt joint body 1 plays a supportive role when joint bears the external force clamping, its top circular arc design can reduce the water pressure fluctuations that unexpected reducing causes, the aluminum alloy collar 3 engages with groove 7 mutual on it by the flange on the joint body 16 and is positioned at outside the joint body 1,3 formation of the external diameter joint body 1 with the level and the aluminum alloy collar and the consistent groove 8 of tubing section shape, tubing 4 insertion grooves 8, with special tool it is executed an even clamping force at the aluminum alloy collar 3 outer circumference, force the aluminum alloy collar 3 and tubing 4 that non-response distortion takes place, one group of projection clamp ring 5 that joint body 1 upper edge external diameter distributes embeds in the tubing 4, plays reliable location and seal action thereby tubing 4 tightly embraced.
The plastic tube joint also has all size forms such as threeway, elbow except that isometrical two lead to, its joint style, structure and two are led to similar, and implementation methods no longer exemplifies.
The utility model is a kind of connector of convenient, practical, safe, reliable, health, Avoided the potential hazard of glue connection to human body, other method of attachment has letter relatively Single, quick, cheap advantage is promoted the use of this joint and will be brought very significant Social benefit and economic benefit.
