Description

Manual micro-gap flange separator Technical Field The utility model belongs to the technical field of petroleum refining and chemical equipment, and particularly relates to a manual micro-gap flange separator. Background In the daily operation of petroleum refining and chemical industry, when blind plates are added between flanges or gaskets are replaced, the problem that gaps of the flanges are tiny is often encountered. The traditional mode of adopting the crow bar operation has a plurality of defects. The contact area of the pry bar and the flange is extremely limited, so that the acting point is too small, the flange gasket is difficult to be applied with sufficient and effective opening force, and in the prying process, the phenomenon of slippage is easy to occur due to unbalanced force of the pry bar. The unstable operation condition not only can damage the flange sealing surface and peripheral related equipment to different degrees such as scratch and abrasion and the like so as to influence the sealing performance and the service life of the equipment, but also is extremely easy to cause safety accidents due to uncontrollability of operation, and forms serious threat to the personal safety of operators, such as injury and the like caused by sliding of a crow bar in the operation process.
