Pipe joint and use method thereof

Abstract

The invention provides a pipe joint, which comprises a joint body, wherein a cavity and an outer hole are formed inside the joint body; the cavity has a first outer insertion port which is used for inserting a soft pipe to be connected and is formed in one end of the joint body; the outer hole has a second outer insertion port which is used for inserting a hard pipe to be connected and is formed in the other end of the joint body; an inner hole is further communicated between the cavity and the outer hole; the inner hole has an inner insertion port formed in the innermost end of the cavity; alining pipe is arranged in the cavity; one end of the lining pipe is inserted into the inner hole through the inner insertion port, and the other end of the lining pipe is provided with a connecting section inserted into the soft pipe; and at least one bulged part is arranged on the connecting section. Compared with the prior art, the pipe joint improves the connection stability between the soft pipe and the hard pipe, solves the problem of narrowing of an inner runner due to inward sinking of the soft pipe, and is simple in structure, low in manufacturing cost and convenient to use. The invention further provides a use method of the pipe joint. The use method has the advantages of simplicity, convenience and easiness in learning.

Description

technical field [0001] The invention relates to the technical field of pipe connection, in particular to a pipe joint and a use method thereof. Background technique [0002] At present, soft pipes and hard pipes are often connected by specially made steel-plastic conversion joints to achieve their respective homogeneous connections. The connection methods can be homogeneous welding, threaded connections, etc. In order to prevent the joints from loosening, there are two types of joints in the prior art: one is a new shell-type steel-plastic joint, and the bush inserted into the soft pipe has inverted teeth; the other is a small flow high-pressure fluid pipe The joint is sealed and connected by adding a sealing ring and a threaded sleeve. [0003] However, there are many disadvantages in the above two joints: special joint parts need special mold manufacturing, which increases the cost; the bushing with inverted teeth may make the soft material during the insertion process or...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides a pipe joint and its use method. The pipe joint improves the connection stability between the soft pipe and the hard pipe, and at the same time solves the problem of the inner flow path caused by the soft pipe concave. Narrowing problem, and simple structure, low production cost, easy to use
