Abstract
The invention discloses a pipeline connection pipe fitting and a connecting method thereof. The connection is that a sealing gasket is arranged between a connector and a curved surface of a convex rib of a connecting pipe, a head part is sheathed on a connecting pipe arranged at the other end of the curved surface of the convex rib of the connecting pipe, and a lug boss of the head part is buckled into a buckling hoop of the head part of the connector; the buckling hoop of the head part of the connector leans against the lug boss of the head part by adopting the way of roll extrusion and clings to the curved surface of the convex rib along the connecting pipe, and the other side of the curved surface of the convex rib clings to the sealing gasket for sealing; therefore, the connection is convenient, the sealing is firm, and the operation is convenient, thus improving the work efficiency, putting an end to the defects of unfirm splicing, reducing inside diameter due to being inward concave and having the remarkable characteristic of being not affected by overheating; the invention overcomes the defects that the accumulated cost is always high since the materials used by the connection pipe fittings, so as to be beneficial to popularization and application.
Description
One, technical field:
A kind of pipeline connecting pipe fitting of the present invention and attaching method thereof, 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, because in water, and 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 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 to add 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, the pipe fitting that 3-has a kind of pipeline material jointing to be connected and sealed by pipeline connecting pipe fitting with the pipe fitting of evagination again, kept internal diameter, Placement is advanced relatively, but owing to the material that connection pipe fitting is used is more, what have still need do the pressure pipe sealing with head part, or with the direct pressure pipe sealing of attaching nut, because the cost of single-piece pipe fitting is higher, the cost of accumulative total is high, has directly influenced the promotion and application of this connection pipe fitting.
Three, summary of the invention:
The objective of the invention is the structure of inverter tube pipe connecting, reach a kind of pipeline connecting pipe fitting of long-time firm connection and attaching method thereof.Its technology is achieved in that the structure that comprises connecting tube, gasket seal, it is characterized in that: its connection is to be provided with gasket seal between the outer convex rib curved surface of joint and connecting tube, be with head part on the connecting tube of the outer convex rib curved surface the other end of connecting tube, the head part boss buckles in the head part button hoop of joint; With the mode of roll extrusion the head part boss that the head part button hoop of joint props up head part is pushed against the outer convex rib curved surface along connecting tube, outer convex rib curved surface opposite side pushes against the gasket seal sealing again, outer convex rib curved surface on the connecting tube can be the garden arc, zigzag fashion, triangle, trapezoidal structure, gasket seal is the tetrafluoroethylene material, 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, be not subjected to the evident characteristic of overheated influence, overcome owing to the used material of connection pipe fitting is more, the cost of single-piece pipe fitting is higher, the defective that the cost of accumulative total is high is beneficial to apply.
Four, description of drawings:
Fig. 1 is a kind of structural representation that connects thin-wall stainless steel embodiment with straight joint;
Wherein, 1-thin-wall stainless steel, 2-head part button hoop, 3-head part, 4-outer convex rib, 5-gasket seal, 6-joint, 7-outer convex rib curved surface, 8-head part boss;
Five, embodiment:
Below in conjunction with accompanying drawing, connecting thin-wall stainless steel with straight joint is example, and the present invention is further described:
See accompanying drawing 1, its connection is to be provided with gasket seal (5) between the outer convex rib curved surface (7) of joint (6) and thin-wall stainless steel (1); be with head part (3) on the thin-wall stainless steel (1) of outer convex rib curved surface (7) the other end of thin-wall stainless steel (1), the head part boss (8) that head part (3) is provided with buckles in the head part button hoop (2) of joint (6).
See accompanying drawing 1; thin-wall stainless steel (1) is inserted in head part (3) back roll extrusion outer convex rib curved surface (7); be provided with gasket seal (5) between the outer convex rib curved surface (7) of straight joint (6) and thin-wall stainless steel (1); be with head part (3) on the thin-wall stainless steel (1) of outer convex rib curved surface (7) the other end of thin-wall stainless steel (1), the head part boss (8) that head part (3) is provided with buckles in the head part button hoop (2) of straight joint (6).Make head part (3) push against outer convex rib curved surface (7) the head part boss (8) that the head part button hoop (2) of straight joint (1) props up head part (3) with the mode of roll extrusion along connecting tube (1), outer convex rib curved surface (7) opposite side pushes against gasket seal (5) sealing again, reaches the connection and the sealing of connecting tube.
Claims (3)
1. pipeline connecting pipe fitting and attaching method thereof, the structure that comprises connecting tube (1), gasket seal (5), it is characterized in that: its connection is to be provided with gasket seal (5) between the outer convex rib curved surface (7) of joint (6) and connecting tube (1), be with head part (3) on the connecting tube (1) of outer convex rib curved surface (7) the other end of connecting tube (1), the head part boss (8) on the head part (3) buckles in the head part button hoop (2) of joint (6).
