fig. 2 is a cross-sectional view of the present invention.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to fig. 1 and 2, the utility model provides an air tightness testing device, its direct detachably sets up in the bottom of tubing hanger processing tool 100 to be connected with the sealing washer 110 cooperation of the inside of tubing hanger processing tool 100, through sealing with tubing hanger processing tool 100 bottom earlier, then let in gas toward tubing hanger processing tool 100 again, thereby to and carry out airtight test to tubing hanger processing tool 100, and then prove the sealing washer damage when tubing hanger processing tool 100 takes place to have gas leakage, otherwise then do not have the problem.

The air tightness testing device sequentially comprises a first connecting surface 210, a second connecting surface 220, a third connecting surface 230, a fourth connecting surface 240 and a fifth connecting surface 250 from top to bottom, wherein the first connecting surface, the second connecting surface, the third connecting surface, the fourth connecting surface and the fifth connecting surface are all circular and correspondingly matched with the shape of the oil pipe hanger processing tool 100.

The diameters of the first connecting surface 210 and the second connecting surface 220 are the same, and are correspondingly matched with the diameter of a sealing ring inside the oil pipe hanger processing tool 100, chamfers 211 are respectively arranged on two sides of the surface of the first connecting surface 210, and the angle of each chamfer 211 is specifically 15 degrees, so that the first connecting surface 210 has a guiding function, when the bottom of the oil pipe hanger processing tool 100 is inserted in the application, the second connecting surface 220 can be inserted into the sealing ring through the guiding of the first connecting surface 210 and is in sealing connection with the sealing ring 110.
