Abstract
The invention provides a movable connector for PP-R pipes. The pipe made of PP-R materials has the advantages of high hardness, good toughness, resistance to high/low temperature and good heat-insulating effect, and is widely used in hot-water supply systems, such as shower bath hot-water pipe in bathroom, geothermal heating water pipe, and heat pipe of solar water heater. One end of the movable PP-R pipe connector is made of PP-R plastic material and the other end thereof is a movable metal pipe with a screw cap. The metal elbow pipe has a groove end at one side, which is she with two or three grooves and a plurality of straight channels, and also has a concave mouth groove at the pipe mouth. When the PP-R material is fused with the groove end inside the die, the grooves, the straight channels and the mouth groove are filled with the filling portion of the PP-R material, so as to prevent the PP-R material from falling off the PP-R end of the metal pipe as well as rotating. The other end of the metal pipe is provided with a raised edge to prevent the screw cap from falling off the raised edge. The screw cap is fused after placing inside the metal tube. The screw cap can move freely on the slide way of the metal pipe.
Description
Technical field the present invention relates to a kind of pipe joint, particularly the PP-R pipe movable joint.
Background technique is on the market PP-R pipe at present, elbow, threeway, straight-through etc. is arranged, but lack the metal joint of being with nut, particularly movable joint; Though a kind of movable straight joint is arranged, Placement is not suitable for some occasions and uses, if connect elbow again, 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, and be that install inadequately in the space sometimes, and part is many more also of no avail.Up to the present, the movable elbow of Quan Qiu PP-R pipe is still blank.
Summary of the invention the present invention lacks the shortcoming of a kind of movable elbow or joint according to above-mentioned pipe fitting, has invented the PP-R pipe movable joint.
PP-R pipe of the present invention is a kind of plastic tube, and PP-R is its international code name.The advantage of this pipe is: hardness height, good toughness, 110 ℃ of heatproof Du Keda, good heat preservation performance, biggest advantage is---joint connects by hot melting mode, and the seal of tube after can guaranteeing to connect is good and be connected firmly, and the PP-R material to reach 30 years aging.This 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, the PP-R pipe should have screw thread, but the character of PP-R is not durable or easy deformation the screw thread of PP-R, so the metal joint of PP-R parcel has just been arranged, an end of metal joint is the PP-R plastic material, and the other end is a metal, and movable nut is arranged.The general employing of metal is copper.Movable joint mainly is made up of PP-R end, metal tube, nut, 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 two, three road grooves and several roads straight trough, enclose the mouth groove that falls in mouth of pipe design one, the effect of groove, straight trough and mouthful groove is when the PP-R material fuses with groove ends in mould, the PP-R material is filled partly can fill with groove, straight trough and mouthful groove, metal tube is wrapped, prevent that the PP-R material from holding or rotate from metal tube PP-R; The other end of metal tube has a chimb at the chimb end, and its diameter is greater than screw cap hole, and the effect of chimb is to block nut to make it can not deviate from from the chimb end of metal tube.Before the fusion of metal tube and PP-R end, must be inserted in nut in the metal tube earlier, nut can be free to slide on the slideway of metal tube, becomes activity, so be movable joint.The benefit of movable joint is that a rotating screw cap just can connect.
The pipe of PP-R pipe joint and PP-R material links together by hot melting mode, earlier the surface of the pipe end of the face of weld of the PP-R end of pipe joint and PP-R 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 invention 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.PP-R the welding mode more seal firmly; 4. long service life.
The PP-R pipe movable joint that the present invention introduces 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 PP-R end from deviating from or rotate from metal tube, can make the style of multiple groove.
