Problems solved by technology

[0002] 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

Embodiment Construction

[0013] figure 1 Shown is a pressure vessel for high-temperature, high-pressure coolant. The cylinder 10 consists of a flange 4 with bolt threaded holes, an annular section 8 welded with coolant inlet and outlet nozzles 5, a transition section and a semicircular bottom The head is welded, wherein the top cover 6 is formed into a semicircle by hot pressing of steel plates, bolt holes are drilled on the periphery of the upper flange 4, and a groove for placing the present invention is opened on the supporting surface. When the high-temperature and high-pressure coolant flows in the pressure vessel, part of it flows directly to the outlet of the pressure vessel along the inner wall of the pressure vessel, and is accompanied by changes in temperature and pressure. Since the pressure vessel top cover and cylinder flange are two independently manufactured The components must be assembled together in the pressure vessel and must ensure high sealing performance. The internal pressure o...

Abstract

The invention relates to an intelligent controlled sealing gasket. In the sealing gasket, the temperature, pressure and deformation of the gasket are measured by a sensor, the data is transmitted to a computer by the sensor, and the computer can know important performance parameters such as compressibility, resiliency and ratios of creep relaxation and stress relaxation at any time by analyzing the data, so that the sealing gasket is in the monitoring state at any time to make the conclusion whether the design requirement is met or not, and can predict what kind of leakage states the gasket lies and whether the design requirement still can be met within a period of time in future or not by analysis.

Description

technical field [0001] 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 [0002] 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 ac...
