Abstract

The utility model discloses a fullering thin-wall connecting pipe fitting with a guide. The fullering thin-wall connecting pipe fitting comprises a thin wall metal pipe, wherein, both ends of a connecting adapter, which are provided with the reinforcing bars, are respectively inserted into the thin wall metal pipe, and the connecting adapter is respectively provided with an inward concavely-curved surface structure which is propped against and sealed with the thin wall metal pipe and the inner wall of the thin wall metal pipe. The utility model has the advantages that the connection is convenient, the sealing is reliable, the operation is easy, the working efficiency is improved, and the infirm sticking is avoided, in particular, the fullering thin-wall connecting pipe fitting has the obvious advantages that the fitting is not influenced by overheat, the material of the connecting adapter of the single pipe fitting is saved by over 70 percent, the defect that the accumulated cost is high continuously because the materials used for the connecting pipe fitting are more, the problem that the sealing material influences the service life is overcome, thereby being favorable for the popularization and the application of the metal pipes.

Description

A kind of clamp-press type thin-wall connecting pipe fittings of tape guide

One, technical field:

The clamp-press type thin-wall connecting pipe fittings of a kind of tape guide of the utility model 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 causes happens occasionally.

Current, there is a kind of pipeline material jointing to add the pipe fitting that Sealing is connected and sealed by pipeline connecting pipe fitting with the pipe fitting of evagination or clamp-press type, Placement is advanced relatively, but owing to the material that connection pipe fitting is used is more, cause cost high, add the life problems of sealing material, directly influenced the promotion and application of this connection pipe fitting.

Three, summary of the invention:

The purpose of this utility model is the clamp-press type connection pipe fitting is improved, and the cancellation seal washer by sheet-metal duct and the direct combination of thin-wall connecting pipe fittings, and can reach the clamp-press type thin-wall connecting pipe fittings of a kind of tape guide that is tightly connected for a long time.Its technology is achieved in that the structure that comprises thin metallic tubd, it is characterized in that: jointing two ends that two ends are provided with stiffening rib insert thin metallic tubd respectively, jointing two ends are respectively equipped with the inner sunken face that offsets with the thin-wall metal inner tube wall and the structure of sealing, the set inner sunken face of jointing can be an arc shaped surface, zigzag fashion, trapezoidal structure, the inner sunken face that jointing two ends are set, it can be respectively the 1-2 bar, be connected with guide pipe with the stiffening rib outer end of jointing disjunctor, the jointing between two thin metallic tubds can be a straight joint, 45-90 ° of elbow, tee union, it is curved to ride, casing coupling.Its tangible advantage is, easy to connect, it is firm to seal, and operation is convenient, improved work efficiency, it is bonding not firm to have stopped, and has the evident characteristic of the heat affecting of not being subjected to especially, and the jointing material economy of single-piece pipe fitting is more than 70%, overcome owing to the used material of connection pipe fitting is more, the defective that cumulative cost is high has overcome the life problems of sealing material, is beneficial to apply.

Four, description of drawings:

Fig. 1 is a main TV structure schematic representation of the present utility model;

Wherein, 1-thin metallic tubd, 2-stiffening rib, 3-inner sunken face, 4-jointing, 5-inner sunken face, 6-thin metallic tubd, 7-stiffening rib;

Five, embodiment:

Below in conjunction with accompanying drawing, the utility model is further described:

See accompanying drawing 1, jointing (4) two ends that two ends are provided with stiffening rib (2), (7) insert thin metallic tubd (1), thin metallic tubd (6) respectively, the inner sunken face (3) that jointing (4) two end inwalls are respectively equipped with and thin metallic tubd (1), thin metallic tubd (6) outer wall offset and seal and the structure of (5), stiffening rib (2), (7) outer end are connected with guide pipe.

See accompanying drawing 1, have jointing (4) one ends that stiffening rib (2), (7) outer end be connected with guide pipe and inserted thin metallic tubd (1), the other end inserts thin metallic tubd (6), inwardly carry out roll extrusion by jointing (4) outer wall, the structure that the inner sunken face (3) that formation jointing (4) inwall and thin metallic tubd (1), thin metallic tubd (6) outer wall closely offset and (5) reach sealing.

This jointing (4) comprises straight joint, 45-90 ° elbow, tee union, curved, the casing coupling of riding.
