Description
Technical field
This utility model belongs to flange equipment technical field, more particularly to a kind of new quick cooling four-way flange apparatus.
Background technology
Flange (Flange), is called flange flange disk or bead.Flange is the part being connected with each other between pipe and pipe,
For the connection between pipe end;Also there is the flange imported and exported used in equipment, for the connection between two equipment, such as reductor
Flange.Flange connects or bump joint, refers to and is connected with each other as one group of combined sealing structure by flange, pad and bolt three
Releasable connection.Pipe flange matches somebody with somebody effective flange in meaning plumbing installation, and the import and export flange of equipment is meant on equipment.
Perforation on flange, bolt are close to two flanges.Sealed with liner between flange.Flange point threaded connection (screwed connection) flange,
Welded flange and clip flange.Flange is all used in pairs, and low pressure pipeline can use silk acting flange, four kilograms of pressure above
Use welded flange.Sealing gasket is added between two panels ring flange, is then fastened with bolt.The flange thickness of different pressures is not
Together, the bolt that they use is also different.Water pump and valve, when connecting with pipeline, phase is also made in the local of these equipment facilities
Corresponding flange shape, also referred to as flange connect.Every connection zero closed using bolt connection simultaneously in two planar perimeters
Part, typically referred to as " flange ", the such as connection of ventilation shaft, this class part are properly termed as " flange type part ".But it is this
