Abstract
The utility model relates to a flange assembly. A flange gasket is arranged between an upper flange and a lower flange. Six evenly-distributed connecting blocks are arranged at the circumferential edge of the lower flange. The outer periphery of the upper flange is equipped with gap grooves that match the connecting blocks. The connecting blocks are embedded into the gap grooves. A first screw hole is disposed in a side surface of each connecting block, and a second screw hole that corresponds to the first screw hole is disposed in each corresponding gap groove. Each connecting block is provided with a bolt that successively passes through the first screw hole and the second screw hole. The beneficial effects of the flange assembly are that firstly, fixing positions of bolts of a conventional flange are changed to prevent the bolts from contacting a flange gasket, the sealing performance of the flange gasket will not be affected, the flange can be connected stably and thus a connecting pipe member can be connected, the sealing performance of a connecting place of the flange is improved, and situations such as water leakage and gas leakage are effectively prevented; and secondly, the connecting blocks are embedded into the gap grooves, so that positioning is achieved by relaying on the connecting blocks, positioning is convenient and accurate, and the connection efficiency is increased.
