Abstract

The invention discloses a clamping type filtering expansion joint. The clamping type filtering expansion joint comprises a butt joint shell, a butt joint pipe is arranged on one side of the butt joint shell, an external connecting pipe is connected to the butt joint pipe, an adjusting joint is connected to the outer end of the external connecting pipe, the external connecting pipe is in threaded connection with the adjusting joint, the butt joint pipe and the external connecting pipe are connected through a buckle, and a sealing nut is arranged between the butt joint pipe and the external connecting pipe. A first filtering ball is arranged in the butt joint shell, a second filtering baffle is arranged in the first filtering ball, and a limiting sheet is arranged on the inner side wall of the butt joint shell and used for limiting the filtering balls. The clamping type filtering expansion joint can play a role in filtering, and the filtering efficiency of the clamping type filtering expansion joint can be greatly improved.

Description

technical field [0001] The invention relates to an expansion joint, in particular to a clamping filter expansion joint. Background technique [0002] The pipeline compensation joint is a new product that connects pumps, valves, pipelines and other equipment with pipelines. They are connected by bolts to make them a whole with a certain amount of displacement, so that they can be installed and maintained according to the size of the on-site installation When adjusted, the axial thrust can be transmitted back to the entire pipeline system during work. This not only improves work efficiency, but also protects pumps, valves and other pipeline equipment to a certain extent. Double-flange loose sleeve limit expansion joints are suitable for pipelines that are connected to flanges on both sides. When installing, adjust the connection length between the two ends of the product and the flanges, tighten the gland bolts evenly in diagonal order, and then adjust the limit nuts. , so t...
