Abstract

The invention discloses an ultralow temperature high-pressure insulation connector which comprises a first short pipe, a left flange, a combined insulation ring, a right flange, a second short pipe and an outer insulation rubber sleeve. The combined insulation ring is clamped between the left flange and the right flange, the first short pipe is connected to the left end of the left flange, the second short pipe is connected to the right end of the right flange, the inner wall of the outer insulation rubber sleeve is coated with an insulation layer to form an internal and external sealed insulation body, the outer insulation rubber sleeve is arranged on the outer surfaces of the first short pipe, the left flange, the combined insulation ring, the right flange and the second short pipe in asleeving manner, and a pair of energy storage sealing rings are arranged on the peripheral part of the combined insulation ring in a surrounding manner. The ultralow temperature high-pressure insulation connector has the beneficial effects that through finite element stress analysis and optimal design, a sealing structure is analyzed and tested, the sealing performance is more reliable, the production process is simple, meanwhile, the anti-bending strength is improved, the structure is compact and attractive, standardization and serialization production can be achieved, the very high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of important pressure pipeline components in cathodic protection systems for steel pipelines, in particular to an ultra-low temperature and high pressure insulation joint. Background technique [0002] As a steel pipeline cathodic protection component, the ultra-low temperature insulating joint has the following main functional requirements: first, reliable insulation performance, second, zero leakage, third, high rigidity, and fourth, long service life. Aiming at the problems of easy leakage, poor insulation performance, small rigidity and short service life in my country's pipelines. [0003] Therefore, it is necessary to propose ultra-low temperature and high voltage insulating joints for the above problems. Contents of the invention [0004] The purpose of the invention is to overcome the deficiencies in the prior art and provide an ultra-low temperature and high voltage insulation joint. [0005] In...
