Abstract

The invention discloses a pressure device for airtightness detection of a casing, and a manufacturing method of the pressure device. The pressure device for the detection comprises a casing body formed in a manner that a first casing is connected with a second casing, wherein the tail end of the second casing is closed; two packer components set by the action of high pressure gas and pressure energy storage rings are arranged on the first casing and the second casing correspondingly; a first one-way valve and a second one-way valve that are opposite in conduction direction are arranged on the casing body between the two packer components; the first casing is provided with an annular hollow structure; and the second casing is provided with a hollow structure. The pressure device for the detection is convenient to use and carry, and can detect the airtightness of the casing on a construction site.

Description

technical field [0001] The invention relates to the field of sealing detection devices for threads of connection parts in pipelines, in particular to a casing air tightness detection pressurization device and a manufacturing method thereof. Background technique [0002] Casing is a commonly used component in the production process of oil and gas fields. It is necessary to connect pipe fittings such as casing and auxiliary tools to form a transmission pipeline to complete the transportation of oil and gas. During use, the casing needs to maintain good airtightness, but airtightness problems are prone to occur at the threaded connection of the casing. Therefore, it is often necessary to perform airtightness testing on the threaded connection parts of these bushings, or to perform airtightness testing on the threaded repaired parts of the repaired bushings. [0003] In the prior art, the method of detecting the airtightness effect of the thread of the casing is: in the labora...
