Embodiment
In order to make the object of electric heating installation using oil as medium sealing gasket of the present utility model, technological scheme and advantage clearly understand, below in conjunction with concrete drawings and the specific embodiments, the utility model is further elaborated.
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
The utility model provides a kind of electric heating installation using oil as medium sealing gasket, comprises at least one deck metal layer and at least one deck buffer layer, described metal layer and the stacked setting in described buffer layer interval.
See Fig. 1 and Fig. 2, this electric heating installation using oil as medium sealing gasket comprises at least two metal layers 100 and at least one deck buffer layer 200, and every layer of buffer layer 200 is arranged between two metal layers 100.When the number of plies is multilayer, the stacked setting of metal layer 100 and buffer layer 200 interval, is that is provided with buffer layer 200 between adjacent two layers metal layer 100, is provided with metal layer 100 between adjacent two layers buffer layer 200.Metal layer in the present embodiment is 8 layers, and buffer layer is 7 layers, and the innermost layer that is in Fig. 1 and outermost surface are metal layer, arranges the intensity that can ensure whole electric heating installation using oil as medium sealing gasket like this.The sectional shape of the electric heating installation using oil as medium sealing gasket in Fig. 1 is ring, and certain electric heating installation using oil as medium sealing gasket of the present utility model also can be other shapes.
The concrete Experimental Comparison of electric heating installation using oil as medium sealing gasket of the present utility model and existing Graphite pad is as follows:
A, pressurized seal are tested
According to internal pressure under actual service condition and production test pressure, tightness pressure testing requirement uses the air pressure such as 0.05mpa, 0.07mpa, 0.1mpa, 0.15mpa, 0.2mpa, 0.3mpa, 0.4mpa, 0.5mpa to increase step by step, retention time must not lower than 2min, test gasket seal gas leakage air pressure and frequency, concrete data are as follows:
The gas leakage air pressure of electric heating installation using oil as medium gasket seal of the present utility model is 0.2mpa as can be seen from the above data, and does not occur that continuity bubble is emerged; And existing Graphite pad gas leakage air pressure is 0.05mpa, occurs continuity, diameter reaches 2mm bubble after reaching 0.2mpa, gas leakage frequency is 5s/.Verify that the gas leakage of electric heating installation using oil as medium sealing gasket of the present utility model is born pressure and is greater than Graphite pad by experiment, and there will not be Seepage in normal operating pressure situation.
B, life test
Carry out normal charge of oil respectively and fill each three the oily spits of fland of oil, energising runs, the contrast seepage time, specific as follows:
As can be seen from the above data, there is oil impregnate in Graphite pad, and exception does not appear in electric heating installation using oil as medium gasket seal of the present utility model in capacity operation situation;
C, torsional test
Use existing welding line leak test plant, contrast two kinds of seal rings under different torsion (80,90,100,110,120) N, gas leakage time of test pressure not each spit of fland body, pressure, bubble frequency and sealed ring deformation amount, specific as follows:
Shown by above data, under equal air pressure, (0.22mpa) Graphite pad occurs that continuity bubble is emerged, and deformation is all greater than sealing gasket of the present utility model under same equal pressure, maximum difference 10%.
Compared with the graphite grazing pad used at present, electric heating installation using oil as medium sealing gasket of the present utility model have employed metal layer and the spaced structure of buffer layer, metal layer can provide certain intensity, buffer layer then makes sealing spacer have certain resilience reaction force, metal layer and buffer layer interval arrange and sealing pad can be made simultaneously to have certain intensity and elasticity, make its good seal performance, tightness is stablized.
Preferably, as a kind of embodiment, described metal layer 100 is carbon steel or stainless steel.Carbon steel or stainless steel elasticity is better, can be good at combining with position to be sealed, sealing gasket can be avoided to be out of shape simultaneously.
