| description | The utility model discloses a filtering device for liquid ammonia pipelines, and belongs to the field of mechanical equipment. The device comprises a pipe body and a plurality of filter nets, wherein the pipe body is provided with an air inlet and an air outlet, and a cavity is formed in the pipe body; the two ends of the pipe body are provided with threaded buckles, and each threaded buckle is used for being hermetically connected with a gas pipeline; the filter nets are located in the cavity of the pipe body; the inner diameter of the air inlet end of the cavity is larger than the inner diameter of the air outlet end of the cavity, a step is formed in the middle of the cavity, the filter nets are located at the step of the cavity, the filter nets are disc-shaped or cone-shaped, and the area of a plurality of filter holes of the filter nets is reduced along the direction from the air inlet to the air outlet; the pipe body is provided with a gapped block for showing up the filter nets; and the gapped block is provided with a transparent cover. The filtering device disclosed by the utility model has the characteristics of being low in manufacturing cost and easy to operate; and the service life of a decrement gauge is improved, the failure rate of an ammonia gas pipeline is reduced, and a maintenance effect on the ammonia gas pipeline is achieved. |
