Abstract
The invention relates to a connecting pipe fitting of a compression thin-walled pipe, which comprises the structures of a connecting pipe, a connecting nut and a connecting pipe fitting, wherein the outer side of an outer convex rib curved surface which is integrated with the connecting pipe is provided with the connecting nut (2); a seal washer is arranged between the connecting pipe fitting andthe connecting pipe; the outer convex rib curved surface can be zigzag, trapezoidal or semicircular; and the connecting pipe can be a thin-walled stainless steel pipe, a thin-walled copper pipe or a composite pipe containing the thin-walled stainless steel pipe and the thin-walled copper pipe. The connecting pipe fitting of the compression thin-walled pipe is convenient in connection, firm in sealing and convenient in operation, improves the working efficiency, puts an end to the defects of unstable adhesion and convex reduced inside diameter, has the obvious characteristic of not being influenced by overheating, saves above 30 percent of materials for a single connecting pipe fitting to relatively overcome the defect of remained high level of the accumulative cost due to more materials used by the connecting pipe fitting, and is favorable for popularization and application.
Description
One, technical field:
Connecting pipe fitting of compression thin-walled pipe of the present invention relates to plumbing pipe and pipeline connection technology field thereof, is applied to thin metallic tubd and connects.
Two, background technique:
At present, the hot-water heating pipe of being supplied on the market adopts the pipeline of traditional galvanized pipe substantially, connects very easy oxide etch with the pipe joint with internal thread, severe water pollution, aluminium-plastic composite pipe can overcome and reduce water pollution, because in water, and easily intensity is lost in the aluminium skin corrosion of centre, 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.Also have thin-wall stainless steel to adopt stainless steel pipe to connect in the market, but relative cost is higher, during connection, guiding is partly shorter, cause connecting tube swing degree big, very likely under the situation of secundly, cause and leak, directly influenced applying that thin-wall stainless steel connects.
Three, summary of the invention:
The objective of the invention is to the clamp-press type connection pipe fitting is improved, design a kind of employing sheet-metal duct connection pipe fitting, and can reach a kind of connecting pipe fitting of compression thin-walled pipe of long-time firm connection.Its technology is achieved in that and comprises connecting tube (1), attaching nut (2), connection pipe fitting (5) is in interior structure, it is characterized in that: be provided with attaching nut (2) with the outer convex rib curved surface outside of connecting tube (1) one, be provided with seal washer (4) between connection pipe fitting (5) and the connecting tube (1), outer convex rib curved surface (3) can be a zigzag fashion, trapezoidal, or half garden shape, seal washer (4) can be a hollow garden cylindricality, conical hollow, hollow garden styletable is worn flange, the flanged (FLGD) structure shape of conical hollow, described connecting tube (1) can be a thin-wall stainless steel; thin-walled copper tube or thin-wall stainless steel is arranged; the thin-walled copper tube is at interior composite pipe; described connection pipe fitting (5) comprises single connecting head; straight-through jointing; 45-90 ° of elbow; threeway jointing; ride and bend interior, the spanner position that the attaching nut is provided with can be a hexagon; octagon or circular circumference are provided with the hook 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, be not subjected to the evident characteristic of overheated influence, the connection pipe fitting material economy of single-piece pipe fitting has overcome relatively owing to the used material of connection pipe fitting is more more than 30%, the defective that cumulative cost is high is beneficial to apply.
Four, description of drawings:
Fig. 1 is for connecting the structural representation that extends out the zigzag fashion connecting tube with straight-through jointing;
Wherein, 1-connecting tube, 2-attaching nut, 5-1-spanner position, 3-outer convex rib curved surface, 4-seal washer, 5-connection pipe fitting, 6-seal washer, 7-attaching nut, 8-connecting tube, 9-outer convex rib curved surface;
Five, embodiment:
Below in conjunction with accompanying drawing, the present invention is further described:
See accompanying drawing 1, be provided with attaching nut (2), be provided with seal washer (4) between connection pipe fitting (5) and the connecting tube (1) with the outer convex rib curved surface (3) of connecting tube (1) the one outside; The other end of connection pipe fitting (5) is provided with attaching nut (7) with the outer convex rib curved surface (9) of connecting tube (8) the one outside, is provided with seal washer (6) between connection pipe fitting (5) and the connecting tube (8).
See accompanying drawing 1, the outer outer convex rib curved surface (3) that is inserted in attaching nut (2) back roll extrusion serrated end face towards connection pipe fitting (5) of connecting tube (1), connecting tube (1) front end that rolls out zigzag fashion outer convex rib curved surface (3) is inserted in seal washer (4) and enters in the hole of connection pipe fitting (5), by spanner at spanner position (2-1), screw into connection pipe fitting (5) internal thread with what attaching nut (2) was provided with, make attaching nut (2) arrive at zigzag fashion outer convex rib curved surface (3) one sides of connecting tube (1), by the opposite side compression seal pad (4) of zigzag fashion outer convex rib curved surface (3) until sealing; Because the connecting means of the other end is identical, no longer be described in detail.
This connection is applicable to that the connection pipe fitting (5) of one or both ends comprises single connecting head, straight-through jointing, 45-90 ° elbow, threeway jointing, rides and bend, and forms the various combination that connects by connecting tube (1).
