Rectangular convex connecting fittings for pipes

Abstract

The invention discloses a rectangular convex connecting pipe fitting of a pipeline. The connection is that a sealing gasket is arranged between a connector and a curved surface of a convex rib of a connecting pipe, a head part is sheathed on a connecting pipe arranged at the other end of the curved surface of the convex rib of the connecting pipe, and a lug boss of the head part is buckled into a buckling hoop of the head part of the connector; the buckling hoop of the head part of the connector leans against the lug boss of the head part by adopting the way of roll extrusion and clings to the curved surface of the convex rib along the connecting pipe, and the other side of the curved surface of the convex rib clings to the sealing gasket for sealing; therefore, the connection is convenient, the sealing is firm, and the operation is convenient, thus improving the work efficiency, putting an end to the defects of unfirm splicing, reducing inside diameter due to being inward concave and having the remarkable characteristic of being not affected by overheating; the invention 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 popularization and application.

Description

1. Technical Field: [0001] The invention relates to a pipe connecting pipe fitting with a rectangular convex shape, which relates to the technical field of pipe and pipe connection pipe fittings, in particular to the technical field of plumbing pipes and pipe connection pipe fittings, and is applied to copper pipes, thin-walled stainless steel pipes, and stainless steel-plastic composite pipes. . 2. Technical background: [0002] At present, the plumbing pipes supplied on the market basically use traditional galvanized pipes and red copper pipes, and their connection methods follow the pipe processing outer wire. Regardless of the direct joints, elbows, tee and other pipe connections, all pipes with internal Wire pipe connectors are easily oxidized and corroded for connection, which affects the actual service life and pollutes water quality. Aluminum-plastic composite pipes can overcome and reduce water pollution. Although the use of snap-fit ​​connectors can be used for pipe con...

Problems solved by technology

[0002] At present, the plumbing pipes supplied in the market basically adopt traditional galvanized pipes and copper pipes, and the connection method follows the processing of outer wires in pipes. Regardless of direct joints, elbows, tees and other pipe connectors, all pipes with internal It is very easy to oxidize and corrode, which affects the actual service life and pollutes the water quality. The aluminum-plastic composite pipe can overcome and reduce water pollution. Although the buckle connector can be used for pipeline connection, because it is in water, And it is easy to corrode the aluminum skin in the middle and lose its strength, causing the aluminum-plastic composite pipe to break and cause water leakage, and because the aluminum-plastic composite pipe is easy to be heated and contracted, over time, it affects the sealing of the buckle connector. The resulting water leakage occurs from time to time, followed by the use of stainless steel-plastic composite pipes to replace the above three pipe materials, but, 1—adhesive method is used to bond the pipes and pipe connectors together, involving the bonding process The requirements are high, the fastness of bonding varies from person to person, relatively lacks technical support, and is difficult to be used in occasions with a certain temperature; 2—Use the concave method at the interface of the pipe material and add the pipe connection pipe fittings for sealed connection , the problem occurred at the cost of sacrificing the inner diameter of the pipe, and the connection is relatively complicated. 3-There is another kind of pipe fittings that use protruding pipe fittings at the interface of the pipe material to seal the connection through the pipe connecting pipe fittings. The inner diameter is maintained and the connection method is relatively advanced. However, due to the large amount of materials used in the connecting pipe fittings, some still need to use the top piece as the pressure pipe seal, or use the connecting nut to directly press the pipe seal. Due to the high cost of a single piece of pipe fittings, the cumulative cost remains high, which directly affects The promotion and application of the connecting pipe fittings
