Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 As shown, the upper flange 3 and the lower flange 4 are respectively welded together with the upper and lower parts of the cylinder 1, and the gaskets 8 are respectively placed on the upper flange 3, Between the lower flanges 4 with four circular through holes evenly distributed, the bolts 7 pass through the corresponding circular through holes on the upper flange 3, lower flange 4 and gasket 8 to fasten the upper flange. The flange plate 3, the lower flange plate 4, and the gasket 8 are tightly attached to the center of the flange plate to achieve a primary seal. The bolt 7 passes through the upper flange plate 3, which has four circular through holes evenly distributed. The circular through hole corresponding to the upper pressure plate 2 and the gasket, fasten the upper flange 3 and the upper pressure plate 2, and the gasket is tightly attached to th...

Abstract

A combined flange comprises flange plates including an upper flange body and a lower flange body, four round through holes are evenly distributed on the flange bodies, round pressing plates are positioned at the upper ends of the flange bodies, round channels in the same mode with the flange bodies are opened at the plane ends of the pressing plates, a sealing gasket is arranged between the upper flange body and the lower flange body, the upper round pressing plate, the upper flange body, the lower flange body and the lower round pressing plate are connected together by a bolt through a round through hole, and the pressing plates and a drum are pressed together through a tightening ring. Accordingly, a sealing structure is formed between the upper flange body and the lower flange body, secondary seal between the flange bodies and the pressing plates and seal between the pressing plates and the drum are achieved, gaps between two flange bodies are eliminated, and the sealing effect of the flange is strengthened.

Description

technical field [0001] The invention relates to the field of mechanical connectors, in particular to a combined flange. Background technique [0002] At present, flanges are widely used in the field of machinery as mechanical connectors. With the rapid development of automated mechanical equipment, the volume and weight requirements of mechanical equipment are getting higher and higher. Since flanges are often unavoidably used in large-scale mechanical systems, the strength requirements for flanges are higher. Flanges It can be seen everywhere when it is applied to the pipeline connection. Through a pair of flanges that cooperate with each other, the pipeline can be well connected. Generally speaking, a pair of flanges are connected to each other by setting corresponding mounting holes, placing gaskets in the middle, and connecting pieces such as bolts. But in many cases now, this connection cannot completely seal the gap between the two flanges, which is prone to leakage ...
