Abstract
The invention discloses a compression thin wall connecting pipe fitting which includes a thin wall metallic conduit, a structure that is internally provided with a sealing washer, a connector and a lock catch; wherein, the connector is provided with the lock catch which fastens down the outer side of a convex curved surface of the thin wall metallic conduit, and the sealing washer is arranged between the connector and a conical surface of the thin wall metallic conduit. The compression thin wall connecting pipe fitting has the obvious advantages of convenient connection, firm sealing and convenient operation, so as to improve the efficacy and save over 80% of the material of the connector of a single pipe fitting; the connecting pipe fitting also relatively 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 saving resources and in favor of popularization and application.
Description
One, technical field:
A kind of compression type thin-wall connecting pipe fittings of the present invention relates to plumbing pipe and pipeline connecting pipe fitting technical field thereof, is applied to thin metallic tubd.
Two, background technique:
At present, the hot-water heating pipe of all supplies on the market adopts the pipeline of traditional galvanized pipe substantially, connects with the pipe joint with internal thread, and very easy oxide etch has influenced actual working life, polluted water; Aluminium-plastic composite pipe can reduce water pollution, because in water, and easily intensity is lost in the aluminium skin corrosion of centre, cause plastic-aluminum combined tracheal rupture, leak, expand with heat and contract with cold easily owing to aluminium-plastic composite pipe again, 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 occasion with uniform temperature; 2-adopts and to add pipeline connecting pipe fitting at the pipeline material jointing with the method for indent and be connected and sealed, and the problem of generation is to be cost to sacrifice internal diameter of the pipeline, and the connection relative complex.3-have again a kind of pipeline material jointing with the pipe fitting of evagination by the pipe fitting that pipeline connecting pipe fitting seals, kept internal diameter.Placement is advanced relatively, but owing to the used material of connection pipe fitting is more, the cost of single-piece pipe fitting is higher, and cumulative cost 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 Placement and the jointing structure of conversion pipeline, reach attenuate jointing thickness, thereby reduce cost per unit, reach a kind of compression type thin-wall connecting pipe fittings of long-time firm connection.Its technology is achieved in that the structure that comprises thin metallic tubd, seal washer, it is characterized in that: jointing is provided with snap close, the snap close of jointing is lived the outer convex surface outside of thin metallic tubd, be provided with seal washer between the conical surface of jointing and thin metallic tubd, the jointing that one side or two ends are provided with fore shaft comprises single connecting head, straight-through jointing, 45-90 ° elbow, threeway jointing, the elbow connection of riding, and the outer convex surface of thin metallic tubd can be circular arc, trapezoidal or zigzag fashion.Its tangible advantage is that easy to connect, it is firm to seal, the operation facility, improved effect, the jointing material economy of single-piece pipe fitting has overcome relatively owing to the used material of connection pipe fitting is more more than 80%, the defective that cumulative cost is high is beneficial to economize on resources, and helps applying.
Four, description of drawings:
Fig. 1 is for connecting the structural representation of the outer convex surface of zigzag fashion with straight-through jointing;
Wherein, 1-thin-wall stainless steel, the outer convex surface of 2-, 3-seal washer, 4-jointing, the 5-conical surface, 6-snap close;
Five, embodiment:
Below in conjunction with accompanying drawing, the present invention is further described:
See accompanying drawing 1, jointing (4) two ends are provided with snap close (6), snap close (6) fastens the zigzag outer convex surface of thin-wall stainless steel (1) (2), and it is compacted and seal to make the end be provided with the seal washer (3) that is provided with between the thin-wall stainless steel (1) of the conical surface (5) and the jointing (4).
See accompanying drawing 1; thin-wall stainless steel (1) needs connecting end to expand the outer convex surface (2) of zigzag fashion; then with thin-wall stainless steel (1) outer end after the conical surface (5) is inserted in seal washer (3); insert in the jointing (4); snap close (6) periphery that is provided with on jointing (4) is carried out roll extrusion; fasten zigzag outer convex surface (2), compress the seal washer (3) that is provided with between the thin-wall stainless steel (1) that is provided with the conical surface (5) and the jointing (4) and seal.Equally, jointing (4) the other end is identical with the programmed sequence of operations that thin-wall stainless steel (1) is tightly connected, and no longer is described in detail.
This connection is applicable to that one or both ends are provided with the jointing of snap close (6) (4) and comprise single connecting head, straight-through jointing, 45-90 ° elbow, threeway jointing, the elbow connection of riding, and forms the various combination that connects by thin metallic tubd (1).
Claims (3)
1. a kind of compression type thin-wall connecting pipe fittings of the present invention, the structure that comprises thin metallic tubd (1), seal washer (3), it is characterized in that: jointing (4) is provided with snap close (6), the snap close (6) of jointing (4) fastens outer convex surface (2) outside of thin metallic tubd (1), is provided with seal washer (3) between the conical surface (5) of jointing (4) and thin metallic tubd (1).
2. a kind of compression type thin-wall connecting pipe fittings according to claim 1 is characterized in that: the jointing (4) that a side or two ends are provided with fore shaft (6) comprises single connecting head, straight-through jointing, 45-90 ° elbow, threeway jointing, the elbow connection of riding.
3. a kind of compression type thin-wall connecting pipe fittings according to claim 1 is characterized in that: the outer convex surface (2) of thin metallic tubd (1) can be circular arc, trapezoidal or zigzag fashion.
