Abstract
The pipe fitting for connecting pipeline includes connecting pipe, connecting nut and sealing gasket, and the connecting pipe has stepped structure in the inner diameter equal to that of the pipe to be connected. The pipe fitting features that the connecting nut has outer thread screwed into the inner thread of the connecting pipe and end contacting one end of the connecting pipe and the sealing gasket is set in the other end. The present invention has the advantages of convenient connection, reliable sealing, convenient operation, high work efficiency, etc.
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, 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 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 is the structure of inverter tube pipe connecting, reaches the connection pipe fitting of long-time firm connection.Its technology is achieved in that and comprises connecting tube, the 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: the attaching nut screws into the pipe connector lug internal thread, the connecting tube curved surface of attaching nut termination conflict stainless steel-plastic composite pipe or trapezoidal faces one side, between pipe connector lug and connecting tube curved surface or trapezoidal faces opposite side, be provided with gasket seal, gasket seal is the tetrafluoroethylene material, and the spanner position that the attaching nut is exposed can be a hexagon, octagon, be evenly equipped with the garden shape of spanner hole.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-pipe connector lug, 4-gasket seal, 5-gasket seal, 6-attaching nut, 7-stainless steel-plastic composite pipe, 8-connecting tube curved surface;
Five, embodiment:
Being connected to example below in conjunction with accompanying drawing with connecting tube and straight joint is further described:
See accompanying drawing 1, be processed into outer convex surface after being inserted in stainless steel-plastic composite pipe (1) of attaching nut (2) and attaching nut (6) and stainless steel-plastic composite pipe (7), attaching nut (2) and attaching nut (6) can't be deviate from from stainless steel-plastic composite pipe (1) and stainless steel-plastic composite pipe (7), attaching nut (2) and attaching nut (6) screw into pipe connector lug (3) internal thread, conflict respectively connecting tube curved surface (8) one sides of stainless steel-plastic composite pipe (1) of attaching nut (2) and attaching nut's (6) termination, and then be pressed on and be provided with the gasket seal of doing with the tetrafluoroethylene material (4) between the opposite side of pipe connector lug (3) and connecting tube curved surface (8), (5), reach the sealing of connection pipe fitting.
See accompanying drawing 1, intercepting stainless steel-plastic composite pipe (1) and stainless steel-plastic composite pipe (7) length, be inserted in attaching nut (2) and attaching nut (6), expand the connecting tube curved surface (8) that two end evaginations with the expanding device, two attaching nuts (2) and attaching nut (6) between the connecting tube curved surface (8) of every stainless steel-plastic composite pipe two end evaginations can't be deviate from, attaching nut (2), attaching nut (6) screws into pipe connector lug (3) internal thread, conflict respectively connecting tube curved surface (8) one sides of stainless steel-plastic composite pipe (1) of attaching nut (2) and attaching nut's (6) termination, and then be pressed on and be provided with the gasket seal of doing with the tetrafluoroethylene material (4) between the opposite side of pipe connector lug (3) and connecting tube curved surface (8), (5), reach the sealing of connection pipe fitting.
Whole piping, according to configuration, the jointing of pipeline (3), 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 (4)
1. a kind of pipeline connecting pipe fitting of the present invention, comprise connecting tube (1), connecting tube (7), attaching nut (2), attaching nut (6) gasket seal (4), gasket seal (5), pipe connector lug (3) endoporus is provided with and connecting tube (1), (7) step that internal diameter is equal is in interior structure, it is characterized in that: attaching nut (2) or attaching nut (6) screw into pipe connector lug (3) internal thread, attaching nut (2), (6) termination conflict connecting tube curved surface (8) or trapezoidal faces one side are provided with gasket seal (4) between pipe connector lug (3) and connecting tube curved surface (8) or trapezoidal faces opposite side, (5).
