Problems solved by technology

Flange connection is an important connection method in pipeline construction. Flange connection is easy to use and can withstand high pressure. In industrial pipelines, flange connection is widely used. However, during the installation or disassembly of ordinary flanges, bolts are required. Installing or removing one by one is time-consuming and labor-intensive
In real life, after the two pipelines are connected, the circulating substances need to be filtered, which requires a separate installation of a filter, which wastes a lot of manpower and material resources and slows down the construction progress.
Moreover, most of the current flanges are connected by fastening bolts. When the fastening bolts fail and are damaged, the flange connection will also fail.

Abstract

The invention relates to an efficient sealing flange which comprises a first flange body, a second flange body, a round filter screen, fastening bolts and nuts. The corresponding positions of the first flange body, the second flange body and the round filter screen are each provided with arc-shaped holes. Each fastening bolt sequentially penetrates the corresponding arc-shaped hole of the first flange body, the corresponding arc-shaped hole of the round filter screen and the corresponding arc-shaped hole of the second flange body to be in threaded connection with the corresponding nut. An annular connecting block is arranged on the side, close to the first flange body, of the second flange body. An external thread is manufactured on the outer side of the annular connecting block. A connecting groove is formed in the first flange body, and an internal thread is manufactured on the inner wall of the connecting groove. The surfaces of the opposite sides of the first flange body and the second flange body are covered with a first rubber sealing layer and a second rubber sealing layer correspondingly. The side, in contact with the first flange body, of each fastening bolt and the side, in contact with the second flange body, of each nut are covered with a third rubber sealing layer and a fourth rubber sealing layer correspondingly. The edge of the outer side of the round filter screen is covered with a rubber sealing ring. According to the efficient sealing flange, by means of the cooperation of the four rubber sealing layers, it is guaranteed that the sealing performance of the flange is efficient and stable, and the flange is prevented from leaking at the connecting position.

Description

technical field [0001] The invention relates to a high-efficiency sealing flange, which belongs to the technical field of pipeline connection. Background technique [0002] Flanges are also called flanges or flanges, which are parts that connect pipes to pipes and are connected to pipe ends. There are holes on the flange, and bolts can be worn. It usually refers to opening several holes for fixing on the periphery of a disc-like metal body for connecting other things. The existing flange connection is to fix two pipelines, pipe fittings or equipment respectively on a flange plate first, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. Flange connection is an important connection method in pipeline construction. Flange connection is easy to use and can withstand high pressure. In industrial pipelines, flange connection is widely used. However, during the installation or disassembly of ordinary flanges, bolts are r...
