Structure-adjustable high-air-tightness stainless steel flange

Abstract

The invention relates to the technical field of hardware fasteners, in particular to a structure-adjustable high-air-tightness stainless steel flange. The stainless steel flange comprises a flange body made of stainless steel. According to the structure-adjustable high-air-tightness stainless steel flange, an annular lateral water retaining cover controlled by a longitudinal adjusting mechanism and a lateral control mechanism is movably assembled on the outer arc-shaped surface, and a lateral water storage tank is formed in the outer side surface of the flange body by adjusting the height of the lateral water retaining cover, so that the air tightness of the connecting surface is improved by injecting liquid into the lateral water storage tank, and the internal safety is greatly improved; the side walls of assembly bolts can be extruded and limited by changing the height of the annular lateral water retaining cover, and the assembly bolts cannot rotate, so that the anti-loosening performance of the assembly bolts is further improved, and the external safety is greatly improved; and the assembly bolts are matched with internal thread assembly and disassembly sealing covers, and an internal adjusting mechanism can be conveniently assembled, disassembled, adjusted and limited, so that the operation is simple and convenient, and the later use cost is lower.

Description

technical field [0001] The invention relates to the technical field of hardware fasteners, in particular to a stainless steel flange with adjustable structure and high airtightness. 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 (sc...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, provide an improved structure adjustable high air-tight stainless steel flange, solve the problem that the traditional flange structure is simple, the structure is fixed, and its structure cannot be changed At the same time, the airtightness of the assembly surface cannot be improved, and the bolts on the assembly surface cannot be locked laterally, resulting in the problem that the safety is still limited
