Description

Gasket ring

Technical Field

The utility model relates to a sealing element used on equipment such as pipelines or pressure vessels, in particular to a sealing gasket.

Background

Gaskets are often used in industrial equipment such as pipes, valves, pumps and pressure vessels, heat exchangers, condensers, etc. The gasket sealing is also the most important static sealing form of detachable parts such as pressure vessels, process equipment, power machines, connecting pipelines and the like in process industrial devices, and the fluid sealing is realized by mutual close contact between flanges and gaskets and reducing or blocking a leakage channel by means of elastic-plastic deformation of the gasket so as to increase the flow resistance.

When the gasket is used in a sealing mode, the compression load on the gasket is easy to change along with time due to the relaxation of the gasket material, temperature and pressure circulation, vibration and other factors. To compensate for these variations, it is desirable to provide a more permanent constant load, for which further improvements are needed.

Disclosure of Invention

The technical problem to be solved by the present invention is to provide a gasket capable of providing a more permanent constant load in view of the above-mentioned prior art.

The technical scheme adopted by the utility model for solving the technical problems is as follows: this packing ring, including the main part, the through-hole has been run through in the central authorities of main part, the main part is by the through-hole from central authorities to the periphery downward extension that inclines gradually, its characterized in that: the main body parts are at least two, and the combination form of the two main body parts can be series connection, parallel connection or combination superposition of the series connection and the parallel connection.

In order to realize different combinations of two or more gasket main body parts, preferably, the upper surface of the main body part adjacent to the outer peripheral part and/or the outer peripheral edge of the through hole is provided with a concave part which is concave downwards from top to bottom, and correspondingly, the upper surface of the main body part adjacent to the outer peripheral part and/or the outer peripheral edge of the through hole is provided with a convex part which is convex downwards from top to bottom. Through the combination and superposition of the concave parts and the convex parts in two or more different gasket main body parts, the series connection, the parallel connection or the different combination and superposition of the series connection and the parallel connection can be quickly realized, wherein the parallel connection of the N gasket main body parts can increase the bearing capacity by N times, and the series connection of the N gasket main body parts can increase the stroke by N times; while the concave and convex portions of the two or more gasket body portions prevent lateral movement when loaded.

Furthermore, the through holes and the outer peripheries of the first washer and the second washer are aligned, the convex part of the outer periphery of the first washer is embedded with the concave part of the outer periphery of the second washer, correspondingly, the convex part of the outer periphery of the first washer is embedded with the concave part of the outer periphery of the second washer, and the parallel connection of the first washer and the second washer is realized. In parallel stack operation, the design typically allows for maximum deflection of the stacked gasket to 75% of the uncompressed shape compression (i.e., the stacked gasket also retains 25% of the uncompressed shape).

Furthermore, the first washer and the second washer are oppositely oriented, and the convex part of the outer peripheral edge of the first washer is embedded with the concave part of the outer peripheral edge of the second washer, so that the first washer and the second washer are connected in series. By connecting in series, the compression load stroke between the two washers can be doubled.

Furthermore, the through holes and the outer peripheries of the first washer and the second washer are aligned, the convex part of the outer periphery of the first washer is embedded with the concave part of the outer periphery of the second washer, correspondingly, the convex part of the outer periphery of the first washer is embedded with the concave part of the outer periphery of the second washer to form parallel connection of the first unit groups, and the parallel connection of the first unit groups and the parallel connection of the second unit groups are embedded with the concave parts of the outer peripheries through the convex parts of the outer peripheries of the first unit groups and the second unit groups, so that the series connection of the first unit groups and the second unit groups is realized. The combined connection mode of series connection and parallel connection can increase the bearing capacity and increase the stroke when bearing load.

Compared with the prior art, the utility model has the advantages that: because can be for establishing ties, parallelly connected or series connection and parallelly connected combination stack between the packing ring, can provide more lasting invariable load, through two packing rings or the different combinations of a plurality of packing rings like this, can make up a lot of packing rings that can adapt to the scene of need not using, strong adaptability, convenient to use.
