Description

Technical Field

[0001] The utility model relates to the technical field of installation tools, and more particularly to a convenient sealing tool for a filter and a gland. Background Art

[0002] In the conveying pipeline, in order to prevent impurities from entering the pump body and the corresponding equipment, a corresponding filter is usually installed on the pipeline on the front side of the main body input end. Most of them are welded with a connecting pipe on the pipeline, and the filter is inserted into the interior of the corresponding pipeline through the connecting pipe. Then the gland is installed on the connecting pipe, and the filter is pressed and fixed by the gland, and the connecting pipe is sealed by the gland. Most of the existing glands are connected to the flange on the connecting pipe by multiple bolts. During use, the filter needs to be cleaned or replaced regularly. Each time the filter is cleaned or replaced, multiple bolts need to be removed. Removing multiple bolts will waste a lot of time, which is not convenient for quick removal of the gland, and reduces the efficiency of cleaning or replacing the filter. Utility Model Content
