Description

Flange gasket installation device

Technical Field

The utility model relates to a flange mounting device, in particular to flange gasket installation device.

Background

The flange is a part for connecting the shafts and is used for connecting pipe ends; there are also flanges on the inlet and outlet of the equipment for the connection between two pieces of equipment, such as reducer flanges. The flange connection or flange joint is a detachable connection which is formed by connecting a flange, a gasket and a bolt with each other to form a group of combined sealing structures. The pipeline flange is a flange used for piping in a pipeline device, and is used on equipment to be an inlet and outlet flange of the equipment. The flanges are provided with holes, and the two flanges are tightly connected through bolts. The flange has good comprehensive performance, so that it can be extensively used in the basic engineering of chemical industry, building, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, water heating, fire-fighting, electric power, spaceflight and shipbuilding, etc.. When the flange is used, gaskets made of various materials are required to be used for sealing, so that the flange has good sealing performance. When the gasket is seriously deviated from the installation position, the sealing performance, the pipeline flow rate and the like are influenced. However, the flange is often fixed on the equipment, and the gasket is often difficult to be accurately and efficiently installed due to the limitation of the angle of the equipment and the like when being replaced.

Disclosure of Invention

The purpose of the invention is as follows: the utility model provides a can make installation reliable, easy operation's a flange gasket installation device between the flange.

The technical scheme is as follows: the utility model provides a flange gasket installation device, includes first flange, second flange, gasket, the gasket is located between first flange, the second flange, and the gasket periphery is equipped with the adjustment subassembly that is used for adjusting the gasket position, and the adjustment subassembly supports tightly in the gasket periphery.

Furthermore, the position adjusting components are semicircular and at least 2.

Furthermore, the position adjusting components are movably connected.

Further, the outer diameter of the position adjusting assembly is the same as that of the flange.

Further, the inner diameter of the position adjusting assembly is the same as the outer diameter of the gasket.

Furthermore, the position adjusting component is made of stainless steel or carbon steel.

Further, the thickness of the position adjusting assembly is the thickness of the gasket plus the flange sealing surface.

Has the beneficial effects that: compared with the prior art, the utility model discloses following effect has: 1. the gasket is arranged between the flanges, and the adjusting assembly is tightly abutted to the periphery of the gasket, so that the problem that the gasket is seriously deviated when the flange is mounted can be effectively solved, and the mounting reliability of the gasket can be greatly improved; 2. simple structure and convenient manufacture.

Detailed Description

The utility model provides a flange gasket installation device, includes first flange, second flange, gasket, and the gasket is located between first flange, the second flange, and the gasket periphery is equipped with adjustment assembly 1 that is used for adjusting the gasket position, and adjustment assembly 1 supports tightly in the gasket periphery.

As shown in the figure, the adjusting components 1 are semicircular and at least 2; the outer diameter D of the flange is the same as the outer diameter of the flange, the inner diameter D of the flange is the same as the outer diameter of the gasket, and the thickness of the flange is the sum of the thickness C of the gasket and the thickness f1 of the sealing surface of the flange; meanwhile, a hole with the same size as the diameter of the bolt hole is formed in the position of the bolt hole when the periphery of the semicircular ring is overlapped with the periphery of the flange plate, and the hole is cut along the direction perpendicular to the L direction of the cutting line along the outer diameter of the bolt hole and the inner side of the semicircular ring.

When the gasket is installed, firstly, half of bolts required for installation penetrate through bolt holes of the flanges, then the gasket is placed between the flanges, finally, the remaining half of bolts penetrate through the bolt holes of the flanges, and nuts are slightly screwed, so that the gasket can be in an active state. Then, inserting the two adjusting assemblies 1 between the two flanges, clamping the bolts at the positions of the holes of the semicircular rings of the adjusting assemblies 1, adjusting the positions, completely clamping the adjusting assemblies 1 on the flange gaskets, adjusting the positions again to enable the peripheries of the adjusting assemblies to be overlapped with the peripheries of the flange plates, screwing the bolts, drawing out the adjusting assemblies 1, and completing installation of the flange gaskets.
