Sealing gasket capable of controlling range of stress relaxation

Abstract

The invention relates to a sealing gasket capable of controlling the range of stress relaxation. The sealing gasket is generally used for the flanged connection of a pipeline and the important sealing connection of a valve, a pressure vessel, and the like and internally provided with a sensor; and the sensor is connected with an external computer. The important performance parameter-stress relaxation of the sealing gasket can be analyzed to enable the stress relaxation of the sealing gasket to be in a monitor state at any time by immediately learning the temperature and the pressure of the sealing gasket; and whether the stress relaxation parameter meets a stress relaxation parameter provided by design requirements or not is analyzed to learn the sealing function state of the sealing gasket in time by learning the stress relaxation parameter.

Description

A sealing gasket with controllable stress relaxation rate range technical field The invention relates to a sealing gasket widely used in pressure vessels, pipeline flanges, pumps and valves, especially a sealing ring of high temperature, high pressure and very important sealing parts. Background technique Under high temperature, high pressure and very important working conditions, the following technical indicators of sealing gaskets must be considered: 1. Ensure that the leakage rate is always within the design value range under the condition of alternating temperature and pressure during operation; 2. In various harsh conditions Under working conditions, it is necessary to keep abreast of the upcoming leakage rate in a timely manner, so that the leakage situation is always under monitoring; this situation is for example the voltage stabilizer of the nuclear power plant, the reactor pressure vessel, the spent fuel processing device, etc.; timely detection of the upcoming l...

Under high temperature, high pressure and very important working conditions, the following technical indicators of sealing gaskets must be considered: 1. Ensure that the leakage rate is always within the design value range under the condition of alternating temperature and pressure during operation; 2. In various harsh conditions Under working conditions, it is necessary to keep abreast of the upcoming leakage rate in a timely manner, so that the leakage situation is always under monitoring; this situation is for example the voltage stabilizer of the nuclear power plant, the reactor pressure vessel, the spent fuel processing device, etc.; timely detection of the upcoming leakage will be beneficial to The prevention of accidents plays an important role; but currently commonly used: solid ring gaskets, wound gaskets, toothed gaskets, turbine gaskets, etc. do not have this function
