Abstract
The present invention relates to tube union, in particular, relates to norminal diameter variable tube union. Plastic pipeline hoop type reducer union includes a pair of tube hoops or a non tube hoop and a tube hoop. The tube hoop is composed of small diameter adaptor, large diameter hoop and connector, non tube hoop is composed of large diameter hoop and connector. It possesses the advantages of simple structure, unimpeded pipeline, easy to maintain, low in mfg. cost etc.
Description
The present invention relates to pipe joint, especially the variable pipe joint of nominal diameter.
The material of pipe can be divided into metallic material and nonmetallic material two big classes.Nonmetallic material have plastics, silicate material and industrial rubber etc.The connection pattern that pipeline is commonly used has flange connection, scyewed joint, welding, the connection of stuffing box formula, spigot and socket type connection, clamp band type connection and FERRULETYPE connection etc.The pipe joint that existing nominal diameter is variable, for example reducing tee, reducing cross etc. all will be cut off pipe when pipeline connects, if reducing numerical value is bigger, also will could connect through reducing repeatedly.Exist that structure is complicated, pipeline easily stops up, the more high drawback of cost.971016224 " plastic pipeline reducing connecting pieces " though overcome above-mentioned drawback preferably, also exist defective non-dismountable, the inconvenience maintenance.
The present invention's purpose be to disclose a kind of simple in structure, pipeline be difficult for stopping up, easy to maintenance, cost is lower, nominal diameter variable new tube joint arbitrarily.
Locking hood type reducing joint for plastic pipeline comprises a pair of pipe anchor ear that has, and perhaps one has only pipe anchor ear and a nothing pipe anchor ear.Form by the adapter of all-in-one-piece path, big footpath anchor ear and link by the pipe anchor ear, do not have the pipe anchor ear and form by all-in-one-piece big footpath anchor ear and link.
Below in conjunction with embodiment shown in the drawings, the present invention is done detailed explanation.
Accompanying drawing 1 is a user mode plan view of the present invention, accompanying drawing 2 and 4 is the embodiment of the invention one plan views, accompanying drawing 3 and 5 is the embodiment of the invention one plan views, accompanying drawing 6 and 8 is the invention process two plan views, accompanying drawing 7 and 9 is the embodiment of the invention two plan views, accompanying drawing 10 and 12 is the embodiment of the invention three plan views, and accompanying drawing 11 and 13 is the embodiment of the invention three plan views.
Shown in accompanying drawing 1 to 13, locking hood type reducing joint for plastic pipeline comprises a pair of pipe anchor ear 2 that has, and perhaps one has only pipe anchor ear 2 and a nothing pipe anchor ear 5.Form by all-in-one-piece path adapter 6, big footpath anchor ear 7 and link 8 by pipe anchor ear 2.Not having pipe anchor ear 5 is made up of the big footpath of all-in-one-piece anchor ear 7 and link 8.Constitute four-way by a pair of by the reducing connecting piece formed of pipe anchor ear 2, and constitute threeway by a reducing connecting piece that has only pipe anchor ear 2 and not have to manage anchor ear 5 to form.
Shown in accompanying drawing 1,2,6,10, it can be light pipe that the path adapter 6 of pipe anchor ear 2 is arranged, and can be threaded pipe, and riffled tube or male-pipe also can be flanged pipes.It is light pipes that path takes over 6, connects with methods such as small diameter tube 1 stick with glue.In like manner, the screw thread path is taken over 6 and use scyewed joint with small diameter tube 1, and flange path adapter 6 connects with small diameter tube 1 usefulness flange.
Shown in accompanying drawing 3,5,7,9,11,13, pipe anchor ear 2 is arranged and do not have the link 8 of managing anchor ear 5 and can be square, as embodiment one; Can be rounded, as embodiment two; Also can be other geometrical shapies, as embodiment three.
The using method of locking hood type reducing joint for plastic pipeline is, with a pair of have the pipe anchor ear 2, perhaps one has only pipe anchor ear 2 and a nothing pipe anchor ear 5 to be contained in large-diameter pipe 4 and outside, add Sealing 3, with screw-nut two anchor ears are tightened together again, again small diameter tube 1 is contained in path and takes on 6 and get final product.
Obviously, the present invention need not cut off large-diameter pipe 4 when the pipeline reducing, arbitrarily reducing.Except embodiment one with small diameter tube 1 be adhesive in path take on 6, small diameter tube 1 and anchor ear all can be pulled down, and reinstall.Therefore have simple in structure, pipeline is smooth and easy, easy to maintenance, advantage such as cost is lower, nominal diameter is variable arbitrarily, can be widely used in water treatment, plumbing field, also can be used for fields such as chemical industry.
In the embodiment shown in the figures, the internal diameter size of embodiment one big footpath anchor ear 7 is φ 32, the internal diameter size of path adapter 6 is φ 16, the internal diameter size of embodiment two big footpath anchor ear 7 is φ 40, the internal diameter size of path adapter 6 is φ 30, the internal diameter size of embodiment three big footpath anchor ear 7 is φ 32, and the internal diameter size of path adapter 6 is φ 25.
