Abstract
A technology and pipe part for jointing two pipes is disclosed. Its joint structure is composed of the composite stainless-steel-plastic pipes with convex curved surface at the position to be jointed, pipe jointer (straight jointer, elbow, three-way etc) with step in its inner surface, jointing nuts with rear end matched with spanner, and gaskets. Its advantages are reliable sealing, easy operation, and firm jointing.
Description
Technical field:
Pipeline connection technology of the present invention and connection pipe fitting, what relate to is pipeline and pipeline connecting pipe fitting design and manufacturing technology field, particularly plumbing pipe and pipeline connecting pipe fitting design and manufacturing technology field thereof are applied to stainless steel-plastic composite pipe.
Technical background:
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 reaching in water oxygenization easily intensity is lost in the aluminium skin corrosion of centre, cause plastic-aluminum combined tracheal rupture, leak, again because aluminium-plastic composite pipe is caught a cold by heat expansion to contract easily, 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 what then come is to substitute above-mentioned three kinds of pipeline materials with stainless steel-plastic composite pipe, but, 1---adopt bonding method that pipeline and pipe joint are bonded together, relate to adhesion technique requirement height, bonding fastness varies with each individual, relatively lack technical support, be difficult to use in field boundary and close with uniform temperature; 2---adopt at the pipeline material jointing and add being connected and sealed of pipeline connecting pipe fitting with the method for indent, 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.
Summary of the invention:
The purpose of pipeline connection technology of the present invention and connection pipe fitting is the shape of reform stainless steel-plastic composite pipe jointing, the structure of inverter tube pipe connecting, and it is firm to reach long-time connection.Its technology is achieved in that and comprises stainless steel-plastic composite pipe, pipe connector lug, the pipeline attaching nut, the structure of pad, pipe connector lug comprises the 90 ° elbows identical with the straight joint inner hole structure, the equal tee joint, reducing T, 45 ° of elbow connections, the elbow connection of riding, its pipeline connection technology is intercepted length-cover nut-expanding-shimming-screwing hermetic, it is characterized in that: the step that the pipe connector lug endoporus is provided with stainless steel-the plastic composite pipe internal diameter equates, the aperture is provided with the inclined-plane, stainless steel-plastic composite pipe has the curved surface of evagination at place, connected pipe connector lug inclined-plane expanding, 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 12 spanner holes of 3 ￣ or six, octagon.Its tangible advantage is, easy to connect, it is firm to seal, and operation is convenient, has improved work efficiency, stopped the defective that bonding not firm and indent reduces internal diameter, is not subjected to overheated influence, enlarged application area.
Description of drawings:
Fig. 1 is the pipeline of pipeline connection technology of the present invention and connection pipe fitting and the structural representation of straight joint connection;
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-stainless steel-plastic composite pipe, the outer convex surface of 9-;
Mode of execution:
Pipeline of the present invention and connection pipe fitting are 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) inclined-plane props up outer convex surface (9).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-plastic composite pipe (1), two pipe joint nuts (3) between (8) two outer convex surfaces (9) can't be deviate from, 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) one end mouth of pipe end faces stretch 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, the spanner hole (2) that is located at pipeline attaching nut (3) is gone up insertion hook spanner, with the hook spanner pipeline attaching nut (3) is screwed, make pipeline connect nut (3) and 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 is relevant, and shape difference but the identical pipe connector lug (5) of inner hole structure have straight joint, 90 ° of elbows, equal tee joint, reducing T, 45 ° of elbow connections, the elbow connection of riding, and the technology of connection is identical with above-mentioned process.
