Abstract
The present invention discloses a rectangular outer convex connecting pipe of pipeline. The connection is that a gasket seal is arranged between a joint and the outer convex rib curved surface of the connecting pipe; a top piece is sleeved on the other end of the outer convex rib curved surface of the connecting pipe; the lug boss of the top piece is buckled to a buckle hoop of the top piece of the joint; the buckle hoop of the top piece of the joint supports the lug boss of the top piece and then tightly supports the outer convex rib curved surface along the connecting pipe by a method of rolling extrusion, then the other side of the outer convex rib curved surface supports the gasket seal to seal; the invention is convenient in connection, firm in seal, convenient in operation, improves work efficiency, stops the disadvantages of splicing unfirmly and reducing the inside diameter of the inner concave, has the characteristic that the connecting pipe is not influenced by overheating and overcomes the disadvantages that the connecting pipe consumes more material and keeps the accumulated cost up, thereby being favorable for popularization and application.
Description
One, technical field:
A kind of pipeline rectangular convex 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, 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-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, 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 structure that the objective of the invention is the inverter tube pipe connecting reaches a kind of pipeline rectangular convex connecting pipe fitting of long-time firm connection.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; The head part boss that head part button hoop props up head part pushes against the outer convex rib curved surface along connecting tube, and outer convex rib curved surface opposite side pushes against the gasket seal sealing again, and the outer convex rib curved surface on the connecting tube can be rectangle or trapezoidal structure, and 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), end face inwardly and gasket seal offset.
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 (2)
1. pipeline rectangular convex connecting pipe fitting, 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).
2. a kind of pipeline rectangular convex connecting pipe fitting according to claim 1 is characterized in that: the outer convex rib curved surface (7) on the connecting tube (1) is rectangle or trapezoidal structure, an end end face inwardly and gasket seal (5) offset.
