Abstract

The invention provides a leakproof interface flange for connecting a water pump. The leakproof interface flange comprises a first flange and a second flange, a set of annular grooves is oppositely formed in the middle portions of the first flange and the second flange, and annular gaskets are arranged in the annular grooves. More than two annular grooves are arranged. The adjacent annular gasketsare connected through annular flat gaskets, the longitudinal section of the annular gaskets is in a circular type and the longitudinal section of the annular flat gaskets is in a square shape, and thediameter of the annular gaskets is slightly larger than the annular grooves. The leakproof interface flange is simple in structure and low in cost, annular dimples are additionally arranged on the flanges and the annular gaskets are matched with the flanges, so that the flanges are tightened and not prone to leaking water, and the service life of sealing rings is greatly prolonged.

Description

technical field [0001] The invention relates to the field of equipment related to water pumps, in particular to a leak-proof interface flange used for connecting water pumps. Background technique [0002] Flange is otherwise known as flange flange or flange. Flanges are parts that are connected to each other between shafts and are used for connection between pipe ends; they are also useful for flanges on equipment inlets and outlets, And can be used as connection between two equipments, example reducer flanges. Flange connection or flange joint refers back to the detachable connection of flange, Gasket and bolt as a team of combined sealing structure. Pipe flange refers back to the flange used for piping in the pipeline installation, And used on the equipment refers to the inlet and outlet flange of the equipment. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets. Flanges are divided into threaded (screw con...
