Abstract

The utility model provides an electrolyte isolation lantern ring used at the threaded connection part of a metal pipe, which comprises an electrolyte isolation lantern ring; the electrolyte isolation collar comprises an inner wall and an outer wall; the outer wall is smooth; the inner wall is provided with annular shaft inner wall grooves distributed at equal intervals; the electrolyte isolation lantern ring covers the stainless steel pipe, the steel joint and the joint of the common steel pipe in a sleeved mode. The utility model discloses an use the electrolyte to keep apart the lantern ring and carry out the cladding with the connector of metal part, reduce electrolyte and the corruption of rainwater to the pipeline of condensing, increase the life of pipeline, the lock hoop stress that the ring axis bulge loop that the both sides outer end of keeping apart the lantern ring was equipped with can increase both ends simultaneously.

Description

Electrolyte isolation lantern ring for threaded connection part of metal pipe

Technical Field

The utility model belongs to metal material fluid conveying pipeline field. In particular to an electrolyte isolation lantern ring used at the threaded connection part of a metal pipe.

Background

The same metal pipes or similar metal pipes are usually connected in a threaded connection mode, and rainwater or other electrolytes are often condensed between a connection included angle and a crack at a connection part to generate an electrochemical corrosion effect, so that the pipeline is corroded and damaged, and economic and material losses are caused.

Disclosure of Invention

To the weak point among the prior art, the utility model provides an electrolyte isolation lantern ring for metal tubular product threaded connection position. The utility model has the characteristics of airtight, the gas elimination.

In order to achieve the above purpose, the utility model discloses technical scheme as follows:

an electrolyte isolation lantern ring for a threaded connection part of a metal pipe comprises an electrolyte isolation lantern ring; the electrolyte isolation collar comprises an inner wall and an outer wall; the outer wall is smooth, and ring axis convex rings are arranged at the ports at the two ends of the outer wall and used for increasing the wall thickness at the two ends of the isolation lantern ring to improve the lock hoop stress at the end part; the inner wall is provided with annular shaft inner wall grooves distributed at equal intervals and used for playing a role in sealing and degassing during combination; the electrolyte isolation lantern ring coats the steel joint and coats the stainless steel pipe and the common steel pipe which are fixedly connected at two ends of the electrolyte isolation lantern ring respectively.

Furthermore, the electrolyte isolation lantern ring is made of weather-resistant rubber or elastic high polymer materials, and electrochemical corrosion of the metal pipeline connecting part is prevented.

Furthermore, the aperture of the electrolyte isolation lantern ring is smaller than the diameters of the stainless steel pipe, the steel joint and the common steel pipe, and the stainless steel pipe, the steel joint and the common steel pipe can be replaced by other metal pipes.

Has the advantages that: the utility model provides a be used for metal tubular product threaded connection position electrolyte to keep apart the lantern ring, adopt to have corresponding weatherability, satisfy the individual insulating property's of intensity elastomer material and process into short tubulose, the aperture is suitable to be less than protected metal pipeline external diameter, makes its complete cladding pipe connection portion contained angle or gap and axial extension suitable distance, can prevent electrolyte or rainwater and pipe connection portion gap and contained angle portion to condense to avoid taking place the electrochemical corrosion effect between the connecting portion metal pipeline.
