Description

Technical Field

[0001] The utility model relates to the technical field of flange detection, in particular to a flange pressure detection device. Background Art

[0002] Butt welding flange, also known as high-neck flange, is a type of flange. The difference between it and other flanges is that it has a long and inclined high neck, and the wall thickness of this high neck gradually transitions, thus improving the discontinuity of stress and increasing the flange strength. It is suitable for pipelines under high temperature, high pressure and sub-zero conditions. After the high-neck flange is processed, it is necessary to sample the high-neck flange to test the pressure strength. Because the high-neck flange is often used in special environments such as high temperature, and under high temperature conditions, the pressure bearing capacity of the high-neck flange is different from that under normal conditions, so the pressure bearing results detected by the traditional pressure resistance detection device are different from those in actual use. In addition, most traditional pressure resistance detection devices are not equipped with protective structures. It is easy for debris to rush out during the detection of the high-neck flange, which is easy to cause safety accidents.

[0003] In the patent with application number CN202221792702.4, an integrated high-neck flange finished product compression detection structure suitable for steel bending is proposed; it can prevent debris from rushing out through a protective door, making it safer to use.

[0004] Although the above technical solution can prevent debris from rushing out through the protective door, it can only perform pressure testing on the high-neck flange under normal conditions, and cannot test the pressure-bearing capacity of the high-neck flange under high temperature conditions, and accidents may occur during actual use.

[0005] As is known from the above, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0019] 2. By setting matching extrusion plates and side pressure plates, the extrusion plate will squeeze the two side pressure plates to both sides when it descends.
