Embodiment Construction

[0011] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0012] Depend on figure 1 It can be seen that the present invention includes: a body 1; the inner diameter of the body 1 gradually decreases in diameter from the flat end on one side to the tip on the other side.

[0013] The present invention adopts the mode that the circle radius gradually decreases from one flat end to the tip, when the steel pipe is inserted into the sealing ring 1 for stamping ( figure 2 , in the picture: stainless steel pipe 5), due to the small radius of the tip, when the pressure is applied, the circle will shrink, and the steel pipe will be wrapped more tightly, ensuring the tightness of the sealing ring and making the hydrostatic test more efficient. high.

[0014] Depend on image 3 Visible: C refers to the stainless steel pipe 5 and the contact surface of the seal ring 1, and simultaneously under the thrust of th...

Abstract

The invention relates to a sealing ring for underwater experiment of a stainless steel pipe, which comprises a main body, wherein an internal diameter of the main body is gradually reduced from a flat end on one side to a pointed end on the other side. The sealing ring provided by the invention has the advantages that the use effect and service life of the sealing ring are largely enhanced because the gradually reduced diameter is adopted, the replacing frequency is reduced, and thus the production efficiency is increased.

Description

technical field [0001] The invention relates to a sealing ring, in particular to a sealing ring for underwater experiments of stainless steel pipes. Background technique [0002] The underwater air pressure test is an important test for the air tightness of stainless steel pipes, and it is very important for checking the air tightness of steel pipes. [0003] In the prior art, the radius of the sealing ring used for the underwater air pressure test of the stainless steel pipe is the same from one end to the tip. The steel pipe is inserted into the sealing ring, and the sealing ring wraps the steel pipe to achieve a sealing effect. In actual operation, it is often tested 3 or 4 times, and the sealing ring cannot meet the sealing requirements and has to be replaced. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a sealing ring for underwater experiments of stainless steel pipes, aiming at solving the above proble...
