Abstract
The pipeline connecting fitting includes connecting pipe, connecting nut, irregular spacer, union with inside step in the size equal to the inner diameter of the connecting pipe. The connecting process includes setting the connecting nut around the connecting pipe, screwing in the union, pressing the containing pipe and pressing the irregular spacer. The present invention has convenient connection, reliable sealing, convenient operation, high efficiency and other advantages.
Description
One, technical field:
A kind of pipeline connecting pipe fitting of the present invention, what relate to is pipeline and pipeline connecting pipe fitting technical field, particularly plumbing pipe and pipeline connecting pipe fitting technical field thereof are applied to copper pipe, thin-wall stainless steel, stainless steel-plastic composite pipe.
Two, 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-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 at the pipeline material jointing and adds being connected and sealed of pipeline connecting pipe fitting with the method for indent, the problem that takes place is to be cost to sacrifice internal diameter of the pipeline, and connection relative complex, and for example, the patent No. 01105997.4 compresses the lock ring cover by the attaching nut, reached the purpose of sealing, but lock ring cover processing is difficulty relatively, and the cost height 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 structure of inverter tube pipe connecting, and it is firm to reach long-time connection.Its technology is achieved in that and comprises that connecting tube, attaching nut, profiled spacer, pipe connector lug endoporus are provided with the structure with stainless steel-step that the plastic composite pipe internal diameter equates, it is characterized in that: be inserted in evagination and become the attaching nut of the connecting tube of cambered surface to screw in pipe connector lug, compress connecting tube and then compress the profiled spacer sealing, the end shape that the attaching nut becomes cambered surface to offset with above-mentioned connecting tube evagination is similar.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, and it is relatively easy to process, and the evident characteristic that cost is low has enlarged application area.
Four, description of drawings:
Fig. 1 is a kind of structural representation that connects stainless steel-plastic composite pipe with straight joint;
Wherein, 1-attaching nut, 2-stainless steel-plastic composite pipe, 3-jointing, 4-profiled spacer, the outer convex globoidal of 5-pipe, 6-stainless steel-plastic composite pipe, 7-attaching nut, 8-profiled spacer;
Five, embodiment:
By the straight joint connection the utility model is further described with pipeline below in conjunction with accompanying drawing:
See accompanying drawing 1, the attaching nut (1,7) of being inserted in the stainless steel-plastic composite pipe (2,6) that is processed into outer convex globoidal screws in jointing (3), compresses stainless steel-plastic composite pipe (2,6) and then compresses profiled spacer (4,8) sealing.
See Fig. 1, intercepting stainless steel-plastic composite pipe (2) and stainless steel-plastic composite pipe (6) length, be inserted in two attaching nuts (1,7) respectively, expand with the expanding device and the outer convex globoidal (5) of two ends, two attaching nuts (1,7) between every stainless steel-plastic composite pipe (2,6) two outer convex globoidals (5) can't be deviate from, attaching nut (1,7) screws into jointing (5) internal thread, compresses stainless steel-plastic composite pipe (2,6) end and then compresses profiled spacer (4,8) sealing.
Whole piping, according to configuration, the jointing of pipeline (5), profile can difference but the identical jointing (5) of endoporus functional structure: straight joint, 90 ° of elbows, equal tee joint, reducing T, 45 ° of elbow connections, the elbow connection etc. of riding are arranged, and the technology of connection is identical with above-mentioned process.
Claims (3)
1. a kind of pipeline connecting pipe fitting of the present invention, comprise that connecting tube (2,7), attaching nut (1,7), profiled spacer (4,8), pipe connector lug (5) endoporus are provided with the structure of the step that equates with connecting tube (2,7) internal diameter, it is characterized in that: the attaching nut (1,7) of being inserted in the connecting tube (2,7) that evagination becomes cambered surface screws in pipe connector lug (5), compresses connecting tube (2,7) and then compresses profiled spacer (4,8) sealing.
2. according to the described a kind of pipeline connecting pipe fitting of claim 1, its feature will in: attaching nut (4,8) is similar with the end shape that above-mentioned connecting tube (2,7) evagination becomes cambered surface to offset.
3. according to the described a kind of pipeline connecting pipe fitting of claim 1, its feature will be in whole piping, according to configuration, the jointing of pipeline (5), profile difference but the identical jointing (5) of endoporus functional structure: straight joint, 90 ° of elbows, equal tee joint, reducing T, 45 ° of elbow connections, the elbow connection of riding are arranged.
