Abstract
The invention discloses a lock compression-type ladder-shaped pipe connecting pipe unit, which comprises a connection joint, and a structure with a metal pipe inside thereof. The connection joint is provided with an ejection piece lock, the outer round end of the ejection piece is provided with thread teeth, the metal pipe and the connection joint are connected when the ejection piece reaches the ladder-shaped outer convex rib curved surface of the metal pipe, the ejection piece lock of the connection joint locks the thread teeth of the ejection piece and compresses a sealing gasket between the connection joint and a stainless steel thin-wall pipe so as to seal. The connection is convenient, the sealing is reliable, and the operation is convenient, thereby improving work efficiency, eliminating insecure adhesion and deficiency in reducing inner diameter in a recess, and being not influenced by over temperature. The material of a single pipe unit is saved by 50% and above, thereby relatively overcoming the disadvantage of high accumulative cost due to more materials used for the connecting pipe so as to be favorable for implementation and application.
Description
One, technical field:
A kind of locking notch compression type laddertron connecting pipe fitting 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 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 structure that the objective of the invention is the inverter tube pipe connecting shortens connecting tube connecting tube length, reduces the weight of jointing, thereby reduces cost per unit, reaches a kind of locking notch compression type laddertron connecting pipe fitting of long-time firm connection.Its technology is achieved in that and comprises jointing, metal tube is in interior structure, it is characterized in that: jointing is provided with the head part fore shaft, the outer nose circle of head part is provided with thread, it is the trapezoidal outer convex rib curved surface that metal tube is arrived on the head part top that metal tube is connected with jointing, by the thread of the head part fore shaft padlock head part of jointing disjunctor and compress jointing and metal tube between the gasket seal that is provided with seal, the jointing that one or both ends are provided with the head part fore shaft comprises single connecting head, straight-through jointing, 45-90 ° of elbow, the threeway jointing, ride and bend interior, the spanner position that the head part outer end 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 jointing material economy of single-piece pipe fitting has overcome relatively owing to the used material of connection pipe fitting is more more than 50%, the defective that cumulative cost is high is beneficial to apply.
Four, description of drawings:
Fig. 1 is for connecting the structural representation of laddertron with straight-through jointing;
Wherein, 1-gasket seal, the trapezoidal outer convex rib curved surface of 2-, 3-head part fore shaft, 4-head part, 4-1-spanner position, 5-thin-wall stainless steel, 6-jointing;
Five, embodiment:
Below in conjunction with accompanying drawing, the present invention is further described:
See accompanying drawing 1, jointing (6) two ends are provided with head part fore shaft (3), the outer nose circle of head part (4) is provided with thread, the outer end is provided with the spanner position (4-1) that is hexagonal; the thread of head part fore shaft (3) the padlock head part (4) of the trapezoidal outer convex rib curved surface (1) of thin-wall stainless steel (5) and jointing (6) disjunctor, the gasket seal (1) that is provided with between jointing (6) and the thin-wall stainless steel (5).
See accompanying drawing 1; outer head part (4) the back trapezoidal outer convex rib curved surface of roll extrusion (2) that is inserted in of thin-wall stainless steel (5); thin-wall stainless steel (5) front end that rolls out trapezoidal outer convex rib curved surface (2) is inserted in sealing gasket to be paid sheet (1) and enter jointing (6); move head part (4) by spanner at spanner position (4-1); the thread that the outer nose circle of head part (4) is provided with screws in the head part fore shaft (3) of disjunctor on the jointing (6); make head part (4) arrive at trapezoidal outer convex rib curved surface (2) one sides of thin-wall stainless steel (5), by the opposite side compression seal pad (1) of trapezoidal outer convex rib curved surface (2) until sealing; Because the connecting means of the other end is identical, no longer be described in detail.
This connection is applicable to that one or both ends are provided with the jointing of head part fore shaft (3) (6) and comprise single connecting head, straight-through jointing, 45-90 ° elbow, threeway jointing, ride and bend, and forms the various combination that connects by thin-wall stainless steel (5).
Claims (3)
