Leak-proof liquid pipeline flange

A pipeline flange and anti-leakage technology, which is applied in the direction of flange connection, pipe/pipe joint/pipe fitting, passing components, etc., can solve the problem of not being able to effectively strengthen the connection between the left flange and the right flange, and not being able to reduce the liquid on the left There are problems such as impact on the joint surface of the flange and the connecting pipe, and no anti-shock device is installed, so as to reduce the impact, increase the sealing performance, and enhance the sealing performance.

Problems solved by technology

[0004] This technical scheme can prevent the sealing ring from falling off, but this scheme cannot effectively strengthen the connection between the left flange and the right flange by tightening the positioning plate with a screw rod, and this scheme does not set an anti-corrosion valve between the left flange and the connecting pipe. The impact device cannot alleviate the impact of the liquid on the joint surface of the left flange and the connecting pipe, so there are still many defects in this technical solution

Abstract

The invention belongs to the field of flanges and particularly relates to an anti-leakage liquid pipeline flange comprising a water inlet pipe, a left flange, a connection pipe, a right flange and a water outlet pipe. The left flange and the right flange are fixedly connected through bolts. The number of the bolts is at least 8. One end of the right flange is fixedly provided with an auxiliary clamping module. The auxiliary clamping module is used for connecting the left flange and the right flange. The other end of the left flange is provided with an annular groove. One end of the right flange is movably connected with the annular groove at the other end of the left flange in a sleeved manner through the auxiliary clamping module. The left end of the auxiliary clamping module is fixedly provided with a seal ring. An anti-shock module is arranged between the left flange and the connection pipe. According to the anti-leakage liquid pipeline flange, the auxiliary clamping module assistsin connecting the left flange and the right flange, so that connection between the left flange and the right flange is prevented from being loose; the anti-shock module lightens shock of liquid in thewater inlet pipe on the combination face between the left flange and the right flange, so that the connection seal performance of the left flange and the right flange is improved.

Description

technical field [0001] The invention belongs to the technical field of flanges, in particular to a liquid leakage prevention pipeline flange. Background technique [0002] Flange, also known as flange flange or flange, is a part that connects pipes to pipes and is used for connection between pipe ends; it is also useful for flanges on equipment inlets and outlets, used for two The connection between two pieces of equipment, such as the flange of the reducer, the pipe flange refers to the flange used for piping in the pipeline installation, and the flange used on the equipment refers to the inlet and outlet flange of the equipment. There are holes on the flange, and the bolts are used in two ways. The flanges are tightly connected, and the flanges are sealed with gaskets. The flanges are divided into threaded connection flanges, welding flanges and clamping flanges. Flanges are used in pairs. Welding flanges are used for pressure, and gaskets are added between the two flange...
