Abstract

A polypropylene plastic flexible joint has the advantages of high rigidity, fine ductility, temperature resistance and fine thermal insulating performance and can be widely applied in hot water pipe engineering such as bathroom shower hot water pipe engineering, geothermal heating water pipe engineering, solar water heater hot water pipe engineering and the like. One end of the polypropylene plastic flexible joint is made of polypropylene plastic materials, and the other end is provided with a metal pipe with a movable nut. One end of the metal pipe is a groove end, two or three grooves and straight flutes are designed at the groove end, and a circle of open groove is designed on a pipe opening. When the polypropylene plastic materials are melted with the groove end in a mold, a polypropylene plastic material filling portion fills the grooves, the straight flutes and the open groove to prevent the polypropylene plastic materials from coming out and rotating on the polypropylene plastic end of the metal pipe. The other end of the metal pipe is provided with a convex edge to clamp the nut and avoid the same coming off from the convex edge end, and the nut can freely slide on a slide way of the metal pipe.

Description

The polypropylene plastics movable joint
Technical field the utility model relates to a kind of pipe joint, particularly the polypropylene plastics movable joint.
Background technique has pp pipeline and polypropylene plastics elbow, threeway, straight-through etc. at present on the market, but lacks the metal joint of being with polypropylene plastics, particularly with the movable joint of polypropylene plastics; Though the movable straight joint of a kind of metal is arranged, and Placement is not suitable for some occasions and uses, it is very big to take up room.The words manufacturing procedure of finishing installing engineering by the existing joint in present market is very complicated, use numerous parts.Though I pass through test of many times success at last for many years, it is 2005101183049 that application number is arranged before, name is called " application of PPR hard tube on shower house is made " and application number is 2008100015586, name is called a plurality of relevant applications such as " PP-R pipe movable joints ", but recognizes the perhaps still not enough invention qualification of this application now.
Summary of the invention the utility model lacks a kind of shortcoming of movable elbow or the joint with polypropylene plastics according to above-mentioned pipe fitting, has invented the polypropylene plastics movable joint.
Polypropylene plastics, PP-R are its international code name.The water pipe advantage made from this polypropylene plastics is: the hardness height, good toughness, 110 ℃ of heatproof Du Keda, good heat preservation performance, biggest advantage is---joint connects by hot melting mode, can guarantee to connect back good airproof performance and being connected firmly, and the polypropylene plastics material to reach 30 years aging.Polypropylene plastic water pipe is widely used in the hot-water line engineering, as: in the engineerings such as Rest Room shower hot-water line, underground heat Heater hose, solar water heater hot-water line.
For making things convenient for the connection of pipe, polypropylene plastics should have screw thread, but directly polypropylene plastics being made screw thread can not be durable or easy deformation, so the metal joint of polypropylene plastics parcel has just been arranged, one end of metal joint has screw thread, the other end is polypropylene plastics plastic material parcel, movable joint be exactly screw thread one end be a movable nut.Movable joint mainly is made up of polypropylene plastics end, metal tube, nut, and metal generally adopts copper material.The structure of for example making an elbow is such: make a bend pipe with metallic, a wherein end of metal winding pipe is groove ends, groove ends is designed twice or three road groove and straight troughs, enclose the mouth groove that falls in mouth of pipe design one, the effect of groove, straight trough and mouthful groove is when the polypropylene plastics material fuses with groove ends in mould, polypropylene plastics material filling part branch fills with groove, straight trough and mouthful groove, metal tube is wrapped, prevent that the polypropylene plastics material from deviating from or rotate from metal tube polypropylene plastics end; The other end of metal tube is at the chimb end, one chimb is arranged, its diameter is greater than screw cap hole, the effect of chimb is to block nut to make it can not deviate from from the chimb end of metal tube, and nut can be free to slide on the slideway of metal tube, and it is movable to become, so be movable joint, metal tube and polypropylene plastics generally adopt the mold injection mode to fuse, and before metal tube and the fusion of polypropylene plastics end, must be inserted in nut in the metal tube earlier.The benefit of movable joint is that a rotating screw cap just can connect.
The pipe of polypropylene plastics joint and polypropylene plastics material links together by hot melting mode, earlier the surface of the pipe end of the face of weld of the polypropylene plastics end of pipe joint and polypropylene plastics material is heated on welding machine, treat to insert fusion rapidly behind its face of weld and the surface melting, both have just linked together after the cooling in tens seconds.
Screw with being connected of nut direct double thread tighten and get final product the therebetween rubber seal.
Technique effect of the present utility model is: 1. be connected to become with other pipe fitting and be easy to; 2. installing and using on the hot water engineering and saved part and man-hour; 3. the welding mode of polypropylene plastics more seals firmly; 4. long service life.
The polypropylene plastics movable joint that the utility model is introduced also can be designed to metal tube directly, and movable joint is made into directly movable and activity threeway.The groove of metal tube and straight trough effect are to prevent that the polypropylene plastics end from deviating from or rotate from metal tube, can make the style of multiple groove.
