Abstract
There is disclosed a pipeline connecting pipe fitting, which includes a connecting pipe, a connecting nut and a seal pad. A structure with steps equal to bore of the connecting pipe is disposed in the inner hole of the pipeline joint. The connecting nut of the connecting pipe is screwed in the pipeline joint, hold-down the connecting pipe and the seal pad and then seal.
Description
One, technical field:
A kind of pipeline connecting pipe fitting of the present invention (2), 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, and the problem of generation is to be cost to sacrifice internal diameter of the pipeline, and the connection relative complex.
Three, summary of the invention:
The purpose of a kind of pipeline connecting pipe fitting of the present invention (2) 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 connecting tube, attaching nut, gasket seal, the pipe connector lug endoporus is provided with the step that equates with the connecting tube internal diameter in interior structure, it is characterized in that: attaching nut's inner plane is encased inside gasket seal, attaching nut's internal thread screws in the pipe connector lug outside thread, and attaching nut's inner plane compresses gasket seal conflict in proper order the connecting tube cambered surface and the pipe connector lug of stainless steel-plastic composite pipe.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 the evident characteristic of overheated influence, enlarged application area.
Four, description of drawings:
Fig. 1 is a kind of structural representation that connects stainless steel-plastic composite pipe embodiment with straight joint; Wherein, 1-stainless steel-plastic composite pipe, 2-attaching nut, 3-gasket seal, 4-pipe connector lug, 5-connecting tube cambered surface;
Five, embodiment:
By the straight joint connection the present invention is further described with pipeline below in conjunction with accompanying drawing:
See accompanying drawing 1, be inserted in the attaching nut (2) of the stainless steel-plastic composite pipe (1) that is processed into outer convex globoidal, attaching nut (2) inner plane is encased inside gasket seal (3), attaching nut (2) internal thread screws in pipe connector lug (4) outside thread, and attaching nut (2) inner plane compresses gasket seal (3) order conflict the connecting tube cambered surface (7) and pipe connector lug (4) of stainless steel-plastic composite pipe (1).
See accompanying drawing 1, intercepting stainless steel-plastic composite pipe (1) length, be inserted in attaching nut (2), expand the connecting tube cambered surface cambered surface (7) that two end evaginations with the expanding device, two attaching nuts (2) between the connecting tube cambered surface (7) of every stainless steel-plastic composite pipe two end evaginations can't be deviate from, attaching nut (2) inner plane is encased inside gasket seal (3), attaching nut (2) internal thread screws in pipe connector lug (4) outside thread, attaching nut (2) inner plane compresses the conflict connecting tube cambered surface (7) of stainless steel-plastic composite pipe (1) of gasket seal (3) order and offsets with pipe connector lug (4) cambered surface, thereby compresses gasket seal (3) and seal.
Whole piping, according to configuration, the jointing of pipeline (4), profile can be different, but the jointing that the endoporus functional structure is identical (4) has straight joint, 90 ° of elbows, equal tee joint, reducing T, 45 ° of elbow connections, the elbow connection etc. of riding, and the technology of connection is identical with above-mentioned process.
Claims (3)
1. invent a kind of pipeline connecting pipe fitting (2), comprise connecting tube (1), attaching nut (4), gasket seal (3), pipe connector lug (4) endoporus is provided with the step (4-1) that equates with connecting tube (1) internal diameter in interior structure, it is characterized in that: attaching nut (2) inner plane is encased inside gasket seal (3), attaching nut (2) internal thread screws in pipe connector lug (4) outside thread, and attaching nut (2) inner plane compresses gasket seal (3) order conflict the connecting tube cambered surface (7) and pipe connector lug (4) of stainless steel-plastic composite pipe (1).
2. according to the described a kind of pipeline connecting pipe fitting of claim 1 (1), it is characterized in that: described connecting tube (1,6) can be copper pipe, thin-wall stainless steel, stainless steel-plastic composite pipe.
3. according to the described a kind of pipeline connecting pipe fitting of claim 1 (1), it is characterized in that: whole piping, according to configuration, the profile of the jointing of pipeline (4) can be different, and the pipe connector lug that the endoporus functional structure is identical (4) has straight joint, 90 ° of elbows, equal tee joint, reducing T, 45 ° of elbow connections, the elbow connection of riding.
