Abstract

The invention discloses a duplex blind plate flange. The duplex blind plate flange comprises a flange part, and further comprises a blind plate part and a projection part, wherein the blind plate part is near the flange part; two through holes are formed in the duplex blind plate flange, and are positioned between the flange part and the blind plate part; the projection part is arranged above the flange part and the blind plate part, and is provided with a push-pull groove; the two ends of the push-pull groove respectively extend to the blind plate part and the flange part; and the flange part, the blind plate part and the projection part are molded as a whole. The duplex blind plate flange can realize rotary switchover and push-pull type switchover, and needs a smaller space in operation, so that the space limitation is reduced, and the duplex blind plate flange can be suitable for narrow areas.

Description

technical field [0001] The invention relates to a double blind flange. Background technique [0002] Double blind flanges are commonly used parts on ships and are used for the connection between pipes. By adjusting the double-connected blind flange, the on-off switching of the pipeline can be realized. At present, when it is necessary to switch the on and off of the pipeline, the bolts on the flange of the double-connected blind plate need to be removed, so it has the disadvantage of inconvenient use; in addition, it requires a large space when switching, so it is not easy to use. Suitable for narrow areas. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double-connected blind flange in order to overcome the defects of inconvenient use and large switching space in the prior art. [0004] The present invention solves the above technical problems through the following technical solutions: [0005] A double-co...
