Description

Cast iron pipe and steel pipe bump structure

Technical Field

The utility model relates to a foundry goods technical field specifically is a cast iron pipe bumps tying with steel pipe and constructs.

Background

Cast iron pipes are cast pipes made of cast iron, which are widely used for water supply, drainage and gas transmission pipelines, and include cast iron straight pipes and pipe fittings. In actual use, when the cast iron pipe is leaked and damaged, the cast iron pipe can be maintained in multiple modes, and if a section of damaged pipe is damaged, the damaged pipe can be replaced by a steel pipe.

However, when the connection between the cast iron pipe and the steel pipe is replaced, the cast iron can shrink very fast, and is easy to crack, and the welding is not firm, so that the welding mode cannot be adopted, and an efficient and stable connection mode is lacked.

Therefore, the utility model provides a cast iron pipe and steel pipe bump and connect structure to solve above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a cast iron pipe bumps with steel pipe and connects structure has solved above-mentioned problem.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: a contact structure of a cast iron pipe and a steel pipe comprises the cast iron pipe and the steel pipe, wherein an interface is arranged between the cast iron pipe and the steel pipe, the interface is fixedly arranged at the tail end of the steel pipe and is matched with the cast iron pipe, a sleeve is sleeved outside the interface, the sleeve and the interface are correspondingly arranged, the tail end of the cast iron pipe is inserted into the sleeve, a sealing and fixing component is arranged in the sleeve, and the sealing and fixing component is arranged between the sleeve and the side wall of the cast iron pipe.

The utility model discloses further inject technical scheme:

preferably, a pipe head is fixedly arranged at one end of the cast iron pipe, and the pipe head is far away from the steel pipe.

Preferably, the sleeve is made of alloy steel castings.

Preferably, the sealing and fixing assembly comprises hemp thread and lead liquid.

Preferably, the steel pipe and the interface are connected in an integrated forming mode.

Advantageous effects

The utility model provides a cast iron pipe bumps tying with steel pipe and constructs. Compared with the prior art, the method has the following beneficial effects:

the utility model discloses a mutually supporting of interface, oversleeve and sealed fixed subassembly isotructure for when carrying out the pipe connection, the oversleeve is sheathe in at the kneck of steel pipe, insert the cast iron pipe in the oversleeve, later with fill up the hemp silk in the clearance of cast iron pipe and oversleeve, then fill up with the lead liquid that melts, can not welded problem when being connected between cast iron pipe and the steel pipe can be solved through this mode, and can reduce the time that the cast iron pipe overhauld, improve maintenance efficiency.
