Loose flange convenient to install

Abstract

The invention relates to a loose flange convenient to install. The loose flange comprises a loose flange assembly, wherein the loose flange assembly comprises a loose flange I and a loose flange II, both the loose flange I and the loose flange II comprise flange plates and annular flat sleeves, and annular sealing flanged edges are formed at the outer edges of one end of the annular flat sleeves.An annular clamping groove, a clamping bulged block and a clamping stop block are formed and arranged, so that the installation and removal are convenient; bolt holes are formed, so that bolts can beconveniently connected and pressed, and high connecting strength is obtained; a sealing washer I and a sealing washer II are arranged, so that high sealing performance is obtained; screw cap seats arearranged, so that the bolts and bolted caps can be effectively protected; transverse antislip strips are arranged, so that the flange plates are convenient to rotate; and the screw cap seats are fixedly arranged on the flange plates, so that the bolts can directly penetrate through the bolt holes and are in threaded connection with the bolt holes, the bolts can be quickly installed, the operationis convenient, and labor is saved.

Description

technical field [0001] The invention relates to an easy-to-install loose flange, which belongs to the technical field of hardware. Background technique [0002] Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate respectively first, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. Pipe fittings and equipment have their own flanges, which also belong to flange connection. Flange connection is an important connection method in pipeline construction, while loose flange is to use flanging, steel ring, etc. to put the flange on the pipe end. The flange can move on the pipe end, the steel ring or flange is the sealing surface, and the function of the flange is to press them tightly. It can be seen that the loose flange is not in contact with the medium because it is blocked by the steel ring or flange, because Flanges are movable and not directly connected to pipes, so they are called lo...
