Abstract
The utility model discloses an intelligent controllable sealing gasket. For the sealing gasket, the temperature, the pressure and the deformation of the gasket are measured by a sensor, the sensor transmits the measured data to a computer, and the computer can learn important performance parameters of the gasket at any time by analyzing the data, wherein the performance parameters include the compression ratio, the resilience ratio, the creep relaxation and the stress relaxation, thus, the sealing gasket is monitored at any time, and a conclusion of whether the sealing gasket meets the design requirements is reached; the problems that which kind of leakage state the gasket is in and whether the gasket can still meet the design requirements in future period can be judged in advance by analysis.
Description
Technical field
The present invention relates to the seal ring of a kind of gasket seal that is widely used in pressurized container, piping flange, pump, the valve, especially high temperature, high pressure and extremely important sealed member.
Background technique
At high temperature, high pressure and extremely important working condition, must consider following gasket seal technical order: 1, guarantee run duration under the situation of temperature and pressure alternation leak-down rate all the time in the design load scope; 2, under various bad working environments, in time understand imminent leak-down rate situation, make the leakage situation in the monitoring state all the time; This situation is such as the voltage stabilizer of nuclear power station, reactor pressure vessel etc.; In time find to be about to the leakage that produces, the prevention of accident is played an important role; And adopt usually at present: the solid torus pad, spirotallic gasket, grooved metal gasket, turbine pad etc. does not all have this function.
Therefore the invention provides the controlled gasket seal of a kind of intelligence,, make pad in the monitoring state at any time, can be in which kind of leak condition by anticipation grasp pad, whether meet design requirement through built-in sensor.
Summary of the invention
The invention provides the controlled gasket seal of a kind of intelligence; This gasket seal is through the residing temperature of sensor measurement pad, pressure and deformation; Can understand the important performance characteristic of pad at any time through measuring these indexs: compressibility, rebound degree, creep relaxation and stress relaxation rate make gasket seal in the monitoring state at any time, through understanding compressibility, rebound degree, creep relaxation and stress relaxation rate parameter; Whether which kind of leak condition analysis and anticipation pad are in, meet design requirement.
The purpose of this invention is to provide the intellectuality that realizes pad, the cooperation through conventional spacers and sensor, computer makes this pad become controlled pad, makes the sealability of pad in the monitoring state at any time.
The controlled gasket seal of this intelligence comprises: 1, gasket seal: this gasket seal can be the PTFE material, also can be to coat pad, the pad pattern of corrugated gasket; 2, sensor, this sensor can be measured the deformation of the residing temperature of pad, pressure and generation and these data are transmitted; 3, computer: the data that the Computer Analysis sensor spreads out of; Draw these important gasket performance desired values of compressibility, rebound degree, creep relaxation and stress relaxation rate; And these desired values are analyzed, draw conclusion and the working state in following a period of time of anticipation that whether pad is in the working state that meets design requirement.
Description of drawings
According to the description and the accompanying drawing of hereinafter, can understand the present invention well, these accompanying drawings have shown non-restrictive example of the present invention.More particularly, in the accompanying drawings:
Further explain below in conjunction with instance:
Fig. 1 is the axial section of pressurized container, contains the sealing of embodiments of the invention junction point between pressure container cylinder flange and top cover flange.
Fig. 2 is the sectional view of the annular intelligent controlled seal ring of the embodiment of the invention shown in Fig. 1.
1 gasket seal, 2 sensors, 3 computers,
4 flanges, 5 ozzles, 6 top covers, 7 pressurized container supporting surfaces, 8 ring segments, 9 guiding devices, 10 shells
Embodiment
Shown in Figure 1 is the pressurized container of high temperature, pressure coolant; Cylindrical shell 10 is welded with freezing mixture by the flange of a strap bolt tapped hole 4, one and imports and exports the ring segment 8 of ozzle 5, a changeover portion and a semicircle lower seal head and be welded; Wherein top cover 6 is hot pressed into semicircle by steel plate; Be drilled with bolt hole at upper flange 4 upper peripheries, have on its supporting surface and place groove of the present invention.When high temperature, pressure coolant flow in pressurized container; Wherein some inwall along pressurized container directly flows to the pressure vessel outlet adapter; And follow the variation of temperature and pressure; Because pressure vessels top cover and shell flange are two independent parts of making, in pressurized container, must be assembled together and will guarantee high leak tightness, internal pressure will be far longer than the external pressure that pressurized container belongs to during the pressurized container operation; For preventing that freezing mixture from leaking, an intelligent controlled seal ring is installed between pressure container cylinder and top cover.
Junction point will bear in the course of the work between pressure container cylinder and the top cover; Expansion that hot coolant produces and contraction and the radial and axial STRESS VARIATION that causes; This variation is very easy to produce and leaks, and still the initial stage of this leakage can't be detected, and when begins leakage and unclear; The present invention is the leakage situation with a kind of simply and effectively design detecting and anticipation seal arrangement.
Through sectional view shown in Fig. 2, the present invention is able to clearer and more definite description.The controlled seal ring of this intelligence is made up of three parts, comprises graphite grazing pad 1, sensor 2 and computer 3.
It is thus clear that the present invention more specifically is provided with sensor in the conventional graphite seal ring, sensor is outside to be connected with computer.
Should be understood that above-mentioned material does not limit the present invention, can also use the different other materials of hardness, like nonmetallic material or other metallic material such as PTFE.
In preferred embodiment; The built-in sensor of gasket seal can be measured temperature, pressure and the pad of pad working environment of living in itself under the pad working state deformation; These parameters are given computer through sensor with data transmission; Computer is analyzed these data, draws conclusion and the working state in following a period of time of anticipation that whether pad is in the working state that meets design requirement.
Should be appreciated that the example that accompanying drawing has only shown to be provided via practical demonstration of the present invention, can change its form and configuration, but can not break away from the scope of the design that the present invention is based on.Any reference mark that in subsidiary claims, provides is that specification and accompanying drawing are read for ease of reference purely, and they do not limit the protection domain of being represented by claim.
