Problems solved by technology

Generally, the sealing surface of the flange is circular and flat, and the two flanges welded at the pipe mouth are installed symmetrically together. The contact between the sealing surfaces of the two flanges is the sealing gasket as the sealing packing. The toroidal surface of this flange is often dislocated and damaged due to installation misalignment, or due to the aging of the sealing gasket itself, it is broken by the positive pressure fluid and causes leakage, which affects normal work.

Abstract

A high-strength water pump flange is composed of a flange plate, a plurality of reinforcing ribs, a plurality of bolt holes, a sealing groove and a sealing pad. The flange plate is provided with the bolt holes used for fixing the reinforcing ribs, and the sealing groove is formed in the end face of the inner side of the flange plate. The flange plate is matched with the other flange plate which is of the same structure. The sealing pad is arranged on the end face of the inner side of the flange plate. The sealing pad is an annular flat pad and is matched with the sealing groove. Each flange plate is provided with 4-8 reinforcing ribs, and each reinforcing rib corresponds to 2-4 bolt holes.

Description

field of invention [0001] The invention relates to a flange, in particular to a high-strength water pump flange. Background technique [0002] The flange is the flange plate. The flange is a part that connects the pipe to the pipe. It is connected to the pipe end and is also useful for the flange on the inlet and outlet of the equipment. . There is a nozzle on the flange, which is used to connect the pipeline. There are a number of bolt holes arranged on the flange. The two flanges are tightly connected by bolts, and the gaskets can be used to seal the flanges. [0003] At present, flanges are widely used as connecting parts in the mechanical field. During work, the flange needs to provide bolt pre-tightening force, and at the same time, it needs to resist the pipeline fluid pressure, which requires a very high strength of the flange, so the strength of the flange has become an important indicator for evaluating the performance of the flange. Generally, the sealing surfac...
