Description

End face double-layer sealing wide-cavity threaded pipeline connecting piece

Technical Field

The utility model relates to a connecting piece field especially relates to the wide chamber threaded pipeline connecting piece of terminal surface double-deck seal.

Background

At present, most of various pipeline connection seals adopt screw thread filling sealing connection, welding, groove type rubber ring clamp sealing connection and clamping type O-shaped ring sealing connection, the construction strength is high, the construction period is long, the technical requirement of operation is high, non-professional personnel and no special mechanical equipment can not operate, the clamping type O-shaped ring sealing connection piece can also use a special thin-wall pipe, otherwise, the construction can not be carried out, and the thin-wall pipe and the pipe are easy to corrode and damage to generate leakage in a short period if the material and the surface treatment of the thin-wall pipe and the pipe are unqualified.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a wide chamber threaded pipeline connecting piece of terminal surface double-deck seal to solve above-mentioned technical problem.

The utility model discloses a solve above-mentioned technical problem, adopt following technical scheme to realize:

the end face double-layer sealed wide-cavity threaded pipeline connecting piece comprises a first connecting pipe, wherein a second connecting pipe is arranged on the right side of the first connecting pipe, a short connecting pipe is arranged between the first connecting pipe and the second connecting pipe, the left end and the right end of the short connecting pipe are fixedly connected and communicated with the first connecting pipe and the second connecting pipe respectively, and threads are arranged on the inner walls of the first connecting pipe and the second connecting pipe; the inside solid fixed ring that is provided with of junction pipe, gu fixed ring and junction pipe inner wall rigid coupling, gu fixed ring both sides all are provided with two sealing rings about, the sealing ring is located the junction pipe.

The utility model has the advantages that:

1. the utility model discloses a set up solid fixed ring and sealing ring, when first connecting pipe, second connecting pipe and pipeline threaded connection, the pipeline end supports on the sealing ring, can effectually play sealed effect, and easy operation, and the technical difficulty is low.
