Description

Technical Field

[0001] The utility model relates to the technical field of gaskets, specifically to a high-performance stress gasket. Background Art

[0002] In the production and manufacturing field of wet coolers in the Chinese industrial refrigeration industry, the current process method is described, which is also a technical bottleneck in this specialty of wet coolers;

[0003] Rubber sheet gaskets are required in wet coolers. Existing rubber sheet gaskets have defects such as poor sealing, corrosion resistance, and high temperature resistance; while silicone sheet gaskets have many disadvantages such as serious deformation, insufficient pressure resistance, and high cost;

[0004] Even if these defects are ignored, in the pressure test process of the production and manufacturing process, the strong stress generated by the internal pressure causes the tube sheet to deform. These factors will make the working conditions of the gasket extremely bad: the reduction of the sealing contact surface causes performance degradation, poor working reliability, or sealing failure. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a high-performance stress gasket to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A high-performance stress gasket, including the lower shell of a wet cooler and the cover of the wet cooler. The top circumference of the lower shell of the wet cooler is connected to the cover of the wet cooler through bolts. It also includes a gasket installed between the lower shell of the wet cooler and the cover of the wet cooler. The cross-section of the gasket is set as an isosceles trapezoid, and the thicker end is arranged inside the lower shell of the wet cooler. Through holes one are opened at the edges of the lower shell of the wet cooler and the cover of the wet cooler. Through holes two are opened at the corresponding positions of the gasket for the through holes one. Bolts are provided on the inner walls of the through holes one and the through holes two.

[0008] In a preferred embodiment of the utility model, the gasket is made of ethylene propylene diene monomer (EPDM) rubber material.

[0009] The additional aspects and advantages of the utility model will be partially given in the following description, partially become obvious from the following description, or be understood through the practice of the utility model.

[0010] 1. According to the working pressure of the equipment, the shape of the gasket is correspondingly changed. The cross-section of the gasket is set as an isosceles trapezoid, and the thicker end is arranged on the inner side of the lower shell of the wet cooler, leaving a thickness loss of the sealing surface caused by stress deformation, so as to overcome the problems caused by stress deformation, poor sealing due to reduced contact area, poor reliability, and sealing failure.

[0011] 2. According to the application scenario of the equipment, the material composition of the gasket is adjusted, and ethylene propylene diene monomer (EPDM) is used to make the gasket, so as to solve many problems such as corrosion, aging, and intolerance to high temperature of the inner and outer exposed surfaces of the sealing material.
