Abstract
The present invention relates to a pipeline connection technology and a pipeline connection pipe member. The pipeline connection pipe member comprises a structure of a stainless steel plastic composite pipe, a pipeline connection joint, a pipeline connection screw nut and a gasket, wherein the pipeline connection joint comprises a straight joint, an elbow joint of 90 degrees, an equal diameter three-way joint, an unequal diameter three-way joint, an elbow joint of 45 degrees and a saddle elbow joint. Steps equal to the inner diameter of the stainless steel plastic composite pipe are arranged in an inner hole of the pipeline connection joint, an inclined plane is arranged on a hole opening, an outwards convex curved plane is expanded on the inclined plane position of the pipeline connection joint connected by the stainless steel plastic composite pipe, a matched curved plane is arranged on the combining position of the inner hole of the pipeline connection screw nut and the outwards convex curved plane, and 3 to 12 spanner holes or hexagonal to octagonal holes are arranged on the back end with a minor diameter. The pipeline connection pipe member has the advantages that the connection is convenient, the sealing is firm and reliable, the operation is convenient, the work efficiency is raised, the defects that the adhesion is not firm and the inner diameter is decreased by inward concaving are eliminated, the pipeline connection pipe member is not influenced by overheating, and the range of application is enlarged.
Description
One, technical field:
A kind of pipeline connecting pipe fitting of the present invention, what relate to is pipeline connecting pipe fitting design and manufacturing technology field, particularly plumbing pipe connection pipe fitting design and manufacturing technology field is applied to stainless steel-plastic composite pipe.
Two, background technique:
At present, the hot-water heating pipe of being supplied on the market adopts traditional galvanized pipe substantially, the pipeline of copper tube, its Placement is continued to use the outer silk of pipeline processing, no matter straight joint, elbow, pipe joints such as threeway, all should connect with pipe joint with internal thread, very easy oxide etch, influenced actual working life, polluted water, aluminium-plastic composite pipe can overcome and reduce water pollution, though using bayonet connection can carry out pipeline connects, owing to metallic aluminium makes aluminium-plastic composite pipe lose intensity in water oxygenization and corrosion, cause plastic-aluminum combined tracheal rupture, leak, owing to being caught a cold by heat expansion easily, aluminium-plastic composite pipe contracts again, time one is of a specified duration, influenced the sealing of bayonet connection, the water leakage phenomenon that is caused happens occasionally, and has influenced applying of aluminium-plastic composite pipe, and that then comes substitutes above-mentioned three kinds of pipeline materials with stainless steel-plastic composite pipe, but, 1-adopts bonding method that pipeline and pipe joint are bonded together, and relates to adhesion technique requirement height, and bonding fastness varies with each individual, relatively lack technical support, be difficult to use in field boundary and close with uniform temperature; 2-adopts and to add pipeline connecting pipe fitting at the pipeline material jointing with the method for indent and be connected and sealed, and the problem of generation is to be cost to sacrifice internal diameter of the pipeline, and the connection relative complex, has directly influenced the practicability of this Placement.
Three, summary of the invention:
The purpose of a kind of pipeline connecting pipe fitting of the present invention is the shape of reform stainless steel-plastic composite pipe jointing, and the structure of inverter tube pipe connecting reaches the firm a kind of pipeline connecting pipe fitting of long-time connection.Its technology is achieved in that and comprises stainless steel-plastic composite pipe, the structure of pipe connector lug, pipeline attaching nut, pad, pipe connector lug comprises 90 ° of elbows, equal tee joint, reducing T, 45 ° of elbow connections, the elbow connection of riding, it is characterized in that: pipe connector lug endoporus aperture is provided with the inclined-plane, stainless steel-plastic composite pipe is convex surface outside place, connected pipe connector lug inclined-plane expanding has, pipeline attaching nut endoporus is provided with the curved surface that matches with outer convex surface junction, and the rear end path is provided with 3-12 spanner hole or six, octagon.Its tangible advantage is, easy to connect, it is firm to seal, and operation is convenient, has improved work efficiency, and it is bonding not firm and reduce the defective of internal diameter to have stopped, and is not subjected to overheated influence, has enlarged application area.
Four, description of drawings:
Fig. 1 is the structural representation of the straight joint connection of a kind of pipeline connecting pipe fitting of the present invention;
Wherein, 1-stainless steel-plastic composite pipe, 2-spanner hole, 3-pipeline attaching nut, 4-pad, 5-pipe connector lug, 6-pipeline attaching nut, 7-pad, 8-plastic stainless-steel composite-tubes, the outer convex surface of 9-;
Five, embodiment:
A kind of pipeline connecting pipe fitting is further described with pipeline and straight joint connection below in conjunction with accompanying drawing:
See accompanying drawing 1, stainless steel-plastic composite pipe (1) and stainless steel-plastic composite pipe (8) stretch in the straight joint (5), be butted on the interior step of pipe connector lug (5) left and right sides two side faces, pad (4), pad (7) is located at respectively between pipe connector lug (5) two end inclined-planes and stainless steel-plastic composite pipe (1) and the outer convex surface of stainless steel-plastic composite pipe (8) (9), pipeline attaching nut (3) is enclosed within outside the outer convex surface (9) on stainless steel-plastic composite pipe (1) and stainless steel-plastic composite pipe (8) external diameter, internal thread screws in pipe connector lug (5) outside thread, and pipeline attaching nut's (3) curved surface props up outer convex surface (9).
See accompanying drawing 1, intercepting stainless steel-plastic composite pipe (1) and stainless steel-plastic composite pipe (8) length, be inserted in two pipeline attaching nuts (3) respectively, expand with the expanding device and the outer convex surface (9) of two ends, make every stainless steel-Polypropylence Sheet composite pipe (1,8) two pipe joint nuts (3) can't be deviate between two outer convex surfaces (9), the end that stainless steel-plastic composite pipe (1) and stainless steel-plastic composite pipe (8) stretch into pipe connector lug (5) is inserted in pad (4,7), stainless steel-plastic composite pipe (1) and stainless steel-plastic composite pipe (8) have pad (4,7) an end mouth of pipe end face stretches into pipe connector lug (5) endoporus, pipeline attaching nut (3) internal thread screws in pipe connector lug (5) outside thread, for making the seal for pipe joints of dressing up, non-leakage, be located on the spanner hole (2) of pipeline attaching nut (3) and plug spanner, with the hook spanner pipeline attaching nut (3) is screwed, make pipeline attaching nut (3) prop up outer convex surface (9), correspondingly push against pad (4) by outer convex surface (9), (7), reach sealing.
Whole piping, according to configuration, pipe connector lug (5) has the technology of straight joint, 90 ° of elbows, equal tee joint, reducing T, 45 ° of elbow connections, the elbow connection of riding, connection identical with above-mentioned process.
