Abstract
The utility model discloses a multipurpose plastic pipe connecting tube, belonging to fluid transmission field and particularly relating to a connecting tube for plastic pipes. Based on the physical theory that plastic pipes have elasticity, the utility model arranges the size of the entrance of the tube to be slightly smaller than the outer diameter of the plastic pipes; meanwhile, the entrance of the tube is arranged to be a splay entrance structure provided with a sharp corner; and after the plastic pipes are inserted into the tube, the parts of the plastic pipes, which contact with the sharp corners, slightly contract, forming a concave groove, thereby reaching the connecting and sealing requirements. Particularly, if the screw threads on the main body of the tube and the screw threadson the screw cap of the tube are arranged to be standard taper pipe threads of 55 degrees or 60 degrees, the tube can not only be connected at the outside of plastic pipes but also be used as a standard external screw provided with taper pipe threads after the screw cap is removed and can be directly connected with a standard valve provided with screw threads and internal threads or other objectsprovided with internal threads, thereby greatly expanding the application range.
Description
Technical field
Multipurpose plasticity pipeline connecting pipe fitting of the present utility model belongs to the fluid transmission field, relates in particular to a kind of connection pipe fitting of plasticity pipeline.
Background technique
The society that builds economizing type is the fundamental state policy of our country, and fluid transmission pipe is that easy operating, connection are reliable, using scope is extensive to the basic demand of various links.And the connection pipe fitting of existing plasticity pipeline mainly to be the main body that has a screw thread couple together with the nut of band screw thread, there is cushion rubber, the locking ring that prevents pull-off and the pad of sealing usefulness the centre.This pipe fitting accessory is various, and the assembling trouble when hydrodynamic pressure is big, is very easy to pull-off.Multipurpose plasticity pipeline connecting pipe fitting of the present utility model has overcome above deficiency, relies on the physics elastic principle of plasticity pipeline itself, has saved accessories such as seal ring, locking ring and pad, terminal with compact integral structure, and easy for installation, using scope is more extensive.
Summary of the invention
The multipurpose plasticity pipeline connecting pipe fitting that provides Applicable scope more extensive, reliable and stable is provided the purpose of this utility model.Owing to made full use of flexible this basic physical principle of plastic tube stage property, the external diameter that is slightly less than the plasticity pipeline that the size of pipe fitting inlet is done, make the splayed configuration structure inlet of band wedge angle simultaneously, hydrodynamic pressure is big more, the dilatancy of plasticity pipeline itself is big more, make connection all the more firm, sealability is good more; In addition, the screw thread that the main body of pipe fitting connects with nut is made the pipe thread of standard, makes pipe fitting can either connect the plasticity pipeline, remove nut after, can also connect the internal thread of corresponding screw thread valve and other pipe fittings, function of use is strengthened greatly.
The utility model is achieved in that multipurpose plasticity pipeline connecting pipe fitting is made up of the main body of band screw thread and the nut of corresponding band screw thread, screw thread can be made 55 ° or 60 ° of taper pipe threads of standard, also can be other forms of standard or odd-pitch screw; In the nut ingress is the splayed configuration structure inlet of band wedge angle, and the undersized of inlet is in the plasticity pipe diameter.
Owing to adopt such scheme, the plasticity pipeline inserts after the splayed configuration structure inlet of the band wedge angle that is slightly less than its diameter on the nut, and the plasticity pipeline is with the position of inlet wedge angle contact, will shrink slightly some, form a groove, because horn structure makes the plasticity pipeline couple together firmly with pipe fitting, plasticity pipeline itself has rubber property simultaneously, realized the function of sealing, and the pressure of fluid is big more, and plasticity pipeline dilatancy is also big more, and the soundness of connection and sealing are strong more; Particularly, after screw thread on the main pipe body and the screw thread on the nut all made 55 ° of standard or 60 ° of taper pipe threads, pipe fitting is except can connecting the plasticity pipeline, nut is removed, it is exactly the outer silk of taper pipe thread of a standard, can directly connect screw thread internal thread valve or other objects with internal thread of standard, using scope is expanded greatly.
The basic structure form of utilizing multipurpose plasticity pipeline connecting pipe fitting homoplasy pipeline to connect can make that straight-through, outer silk,, reducing outer silk straight-through to silk, reducing, reducing are seven logical to curved logical, six logical to curved logical, the threeway of silk, screw thread threeway, reducing tee, the threeway of reducing screw thread, four-way, screw thread four-way, five-way, screw thread five-way, six logical, screw thread to curved logical, the reducing of curved logical, the outer silk of reducing of curved logical, the reducing of silk, seven logical, the screw thread of silk, curved logical, outer silk, internal thread, inside and outside silk, valve, flange, plug, the first-class various plasticity pipeline connecting pipe fittings of outer pipe plug.
