The flange is widely applied to the mechanical field as a connecting piece. Since it is often unavoidable to apply the flange to a large mechanical system, the flange is everywhere visible when applied to the pipe connection, and the pipes can be well connected by a pair of flanges which are fitted to each other. Flange connection is a detachable joint which is formed by fixing two pipelines, pipe fittings or equipment on a flange respectively, then adding a flange pad between the two flanges, and finally tightening the two flanges by bolts to tightly combine the two flanges. A connection between a stationary pipe to a rotating or reciprocating device can be achieved.
The connection of existing metal or plastic pipes is usually accomplished by welding, flange connection, clamping clips or pipe clips. The welding and flange connection need to be powered on and off, the efficiency is low, and the potential safety hazard is large. The clamping hoop or the pipe hoop is fast in construction, but basically has no axial drag resistance and vibration resistance, the pipeline can be firmly connected only by a matched fixing device on the pipeline, and the conventional flange is generally only provided with a through hole for butting a pipe orifice, so that the butt joint on a single pipeline line can be carried out, and the operation of fluid diversion cannot be met in many times. Even if the fluid can be divided, the flanges are in single butt joint, so that a plurality of flanges are needed to be matched, the consumption of the flanges is high, the number of connecting ports is large, and the possibility of fluid leakage is greatly improved. It is therefore desirable to provide a connection flange that is easy to connect.
