Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a high-strength and high-sealing flange. Background Art

[0002] Flange is a part that connects pipes to each other and is used to connect pipe ends. There are bolt holes on the flange, and the bolts connect the two flanges tightly. Flange connection is an important connection method in pipeline construction. Flange connection is easy to use and can withstand greater pressure. Flange connection is widely used in industrial pipelines.

[0003] The utility model patent application document with the publication number "CN215294018U" discloses a high-strength sealing flange, which mainly includes a first flange, a second flange, a fixed block and a clamping block. The technology sets a fixed block and a clamping block. When the flange needs to be connected and fixed, the second flange is rotated, and the clamping block enters the placement cavity on the fixed block. During the process of the clamping block entering the placement cavity, the clamping block conflicts with the side wall of the placement cavity, so that the clamping block drives the second flange to move closer to the first flange, thereby improving the tightness between the first flange and the second flange. The bolts are rotated to fix the first flange and the second flange together, and the placement cavity on the fixed block fixes the clamping block, and the first flange and the second flange are tightly fixed together, thereby improving the overall strength of the flange and the firmness of the connection.

[0004] The high-strength sealing flange disclosed in the above document has the following defects: the high-strength and high-sealing flange is connected to the first flange and the second flange by bolts. Although the bolts have a fixing effect, the process of removing the bolts is cumbersome. If there is no tool for tightening the bolts, the bolts cannot be removed from the connection between the first flange and the second flange, and thus the first flange and the second flange cannot be repaired.

[0005] It can be seen from this that the existing high-strength sealing flange does not have a quick-release structure, and it is necessary to improve the existing deficiencies and provide a high-strength and high-sealing flange. Summary of the invention
