Abstract
The utility model discloses a connecting fitting whose technology is realize through: the utility model comprises a metal pipe, a top piece buckle, a joint connector and a seal washer. The curved surface of the outward cambered rib is positioned at the pipe orifice of the metal pipe; a seal washer is arranged between the curved surface of the outward cambered rib of the connect pipe within the joint connector and the top fitting buckle. The utility model has the advantages of convenient connection, reliable sealing and easy application and can improve work efficiency, avoid the defect of loose sticking and inward camber which decrease the inner diameter. The utility model is free from the effect of over heat and overcomes the shortage of high unit cost and high accumulated overall cost due to the reason of too much material for the connecting fittings.
Description
One, technical field:
A kind of connection pipe fitting of the utility model relates to plumbing pipe and pipeline connecting pipe fitting technical field thereof, is applied to metal tube.
Two, technical background:
At present, the hot-water heating pipe of being supplied on the market adopts the pipeline of traditional galvanized pipe substantially, 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, because in water, and, cause plastic-aluminum combined tracheal rupture easily with the aluminium skin corrosion of centre and lose intensity, leak, again because aluminium-plastic composite pipe is caught a cold by heat expansion to contract easily, time one is of a specified duration, has influenced the sealing of bayonet connection, and the water leakage phenomenon that is caused happens occasionally, 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, 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, the cost of single-piece pipe fitting is higher, cumulative cost is high, has directly influenced the promotion and application of this connection pipe fitting.
Three, summary of the invention:
The purpose of this utility model is the structure of inverter tube pipe connecting, shortens connecting tube and connection pipe fitting length, reduces a kind of connection pipe fitting that cost per unit just can reach long-time firm connection.Its technology is achieved in that the structure that comprises metal tube, head part button hoop, jointing, seal washer, and it is characterized in that: the outer convex rib curved surface is located at the metal tube mouth of pipe; The outer convex rib curved surface of the connecting tube in the jointing and head part are buckled and are provided with seal washer between the hoop.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 relatively owing to the used material of connection pipe fitting is more, the cost of single-piece pipe fitting is higher, the defective that cumulative cost is high is beneficial to apply.
Four, description of drawings:
Fig. 1 is the structural representation of example for the straight-through jointing of a kind of usefulness connects thin-wall stainless steel;
Wherein, 1-thin-wall stainless steel, 2-head part button hoop, 3-jointing, 4-seal washer, 5-outer convex rib curved surface, 6-seal washer, 7-head part are buckled hoop, 8-thin-wall stainless steel;
Five, embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
See accompanying drawing 1, its connection connects with a side to be narrated, the outer convex rib curved surface (5) of the connecting tube (1) in the jointing (3) and head part are buckled and are provided with seal washer (4) between the hoop (3), and head part button hoop (3) seals by being threaded and being pressed into jointing (3).
See accompanying drawing 1; thin-wall stainless steel (1) is inserted in seal washer (4), head part buckles hoop (3) back roll extrusion outer convex rib curved surface (5); the thin-wall stainless steel (1) that rolls out outer convex rib curved surface (5) advances jointing (3); head part button hoop (3) is threaded into jointing (3) by what match; make head part button hoop (3) push against seal washer (4) along thin-wall stainless steel (1); seal washer (4) parcel outer convex rib curved surface (5) also compresses, and reaches the connection and the sealing of thin-wall stainless steel (1); The connecting means of the opposite side of jointing (4) is identical, no longer is described in detail, and omits.
This connection be applicable to accompanying drawing in the identical various connection pipe fittings of immanent structure described: comprise jointing, threeway, ride curvedly etc., implement the connections of the different trends of pipeline.
Claims (1)
1. connection pipe fitting comprises the structure of metal tube (1), head part button hoop (2), jointing (3), seal washer (4), and it is characterized in that: outer convex rib curved surface (5) is located at metal tube (1) mouth of pipe; The outer convex rib curved surface (5) of the metal tube (1) in the jointing (3) and head part are buckled and are provided with seal washer (4) between the hoop (2).
