Description
Technical field
This utility model belongs to plastics forming technique field, relates to a kind of PP-R screw thread straight joint.
Background technology
Along with the pipe joint connected installed by popularizing of plastic tube application, cupric mold insert pipe fitting or other metal inserted piece pipe fitting as plastic tube, it is applied in engineering and also gets more and more；The joint particularly using this metal inserted piece pipe fitting in heating and ventilation project is more, often causes mold insert to seal bad with the joint portion of molded portion because of the alternate of cold fluid and hot fluid, in use causes fluid to leak；Also contact loosely because of interior metal inlaying part with outer tube, cause both relatively to loosen or the abjection of metal part, make pipe fitting joint lose efficacy.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of PP-R screw thread straight joint, can effectively solve because of the leakage of fluid cold fluid and hot fluid alternate process medium fluid, and can effectively prevent rotationally and axially moving of adapter sleeve and connecting tube.
For reaching above-mentioned purpose, this utility model following technical scheme of offer:
PP-R screw thread straight joint, including adapter sleeve, connecting tube, described connecting tube is the metalwork having and connecting screw thread, described adapter sleeve is to be molded all-in-one-piece working of plastics with connecting tube, described connecting tube is provided with multiple closure gasket groove on the periphery being connected with adapter sleeve, and described connecting tube is additionally provided with multiple retaining anti-rotation groove on the periphery being connected with adapter sleeve.
Further, described connecting tube is provided with sealed groove on the end face being connected with adapter sleeve.
Further, described closure gasket groove is the rectangle annular groove concentric with connecting tube.
Further, described sealed groove is the rectangle annular groove concentric with connecting tube.
Further, described retaining anti-rotation groove is provided with four and is distributed on the same cross section of connecting tube, and it is square for making the connecting tube cross section herein.
Further, the other end of described adapter sleeve is the straight length for connecting plastic tube.
Further, the periphery of described straight length is provided with reinforcement.
Further, the periphery of described adapter sleeve is provided with screw grip multiple projections.
The beneficial effects of the utility model are:
The first, metal connecting tube is set inside adapter sleeve, and adapter sleeve and metal connecting tube are molded into one, connect two sections of plastic tubes with having the metal connecting tube connecting screw thread, substantially prolongs the service life of plastic pipe joint head thread.
The second, on metal adapter sleeve periphery, it is provided with multiple annular groove sealed, after being molded into one, is full of plastics in each annular groove, constitutes a lot of sealing ring, can effectively prevent liquid from leaking.
3rd, connecting tube is provided with sealed groove on the end face being connected with adapter sleeve, after being molded into one, is full of plastics, constitutes a lot of sealing ring in each groove, more efficient can prevent liquid from leaking.
4th, on metal adapter sleeve periphery, it is provided with multiple retaining anti-rotation groove, after being molded into one, is full of multiple boss that plastics are formed with adapter sleeve one in retaining anti-rotation groove and embeds in connecting tube, thus limit rotationally and axially moving of adapter sleeve and connecting tube.
