Abstract
The utility model relates to an anti-surge high temperature-resistant elastic seal and a copulate flange which is matched with the elastic seal. The elastic seal comprises an elastic seal ring and a spring that is fixed in the elastic seal ring. The inner surface of the elastic seal ring is provided with a wedge-shaped ring groove, and the spring is of dividers-shaped and the top of the spring is arranged at the bottom of the ring groove of the elastic seal ring. The two nether ends of the spring are respectively extended to the upper ring gear and lower ring gear of the elastic seal ring. Moreover, the flange, which is matched with the elastic seal ring, is divided into upper flanges and lower flanges that are fixed together by bolts and form a circular cavity for the arrangement of the elastic seal ring. When the utility model is cooperatively used, the elastic seal ring is positioned in the circular cavity that is formed by the upper flanges and lower flanges, and is fastened by the bolts. The utility model applies to the intermittent change circumstance of the temperature and pressure, under which the utility model has good sealing effect, no leakage and a long service life. Since the relatively good performance of high temperature resistance, high-pressured resistance and acid resistance, and the utility model can be recycled.
Description
One, technical field: the flange that the utility model relates to Sealing and be used specifically is the flange that has the shock-resistant resistant to elevated temperatures elastomer seal of spring and be mated use.
Two, background technique: existing tankage such as heat exchanger etc., its end socket and cylindrical shell are except that direct welding, because of the flanges that adopt between arts demand end socket and the cylindrical shell connect more, and cushion rubber, poly-tetrafluoro circle etc. are all adopted in being sealed in of upper and lower flange under the normal temperature situation, these seal rings self have certain elasticity, and sealing effect is better.The sealed environment big slightly for working pressure, that temperature is high slightly adopts asbestos packing, graphite wound gasket etc. to seal more, this seal form can reach seal request under the operating mode of equipment continuous operation, if but the equipment operation operating mode is not a continuity, but it is intermittent, through temperature variation repeatedly, compression shock adds when temperature is high, the flange bolt expanded by heating, the elasticity of seal ring own is little simultaneously, so just causes sealing leakage phenomenon incessantly to occur, causes damage.And having certain flexible cushion rubber to be applicable to normal temperature usually, the high slightly colloid of temperature lost efficacy, and can not be used in the above-mentioned operating mode.
Three, summary of the invention:
The purpose of this utility model provides a kind of shock-resistant resistant to elevated temperatures elastomer seal, and this Sealing is fit to the applied environment that temperature, pressure intermittently change, and the good sealing effect under this applied environment does not leak; The flange that the utility model also provides a kind of and this Sealing to be used.
The purpose of this utility model is to be achieved by following technical proposals: a kind of shock-resistant resistant to elevated temperatures elastomer seal constitutes by adding shock mount in the elastic sealing ring, the elastic packing ring inner surface has the wedge shape annular groove, the disconnected cross section of spring is compass shaped, the top is positioned at the bottom of the annular groove of elastic sealing ring, and the two ends, bottom extend to respectively in the upper and lower ring tooth of elastic sealing ring.
A kind of shock-resistant resistant to elevated temperatures elastomer seal constitutes by adding shock mount in the elastic sealing ring, the elastic packing ring inner surface has the wedge shape annular groove, the disconnected cross section of spring is circular arc, and the top is positioned at the bottom of the annular groove of elastic sealing ring, and the two ends, bottom extend to respectively in the upper and lower ring tooth of elastic sealing ring.
The flange that Sealing in a kind of and the such scheme is used is bolted together after to dress by upper and lower flange, and upper and lower flange forms the toroidal cavity of placing elastic sealing ring to adorning the back.
The utlity model has following advantage and good effect:
Adding shock mount in elastic sealing ring can increase the elasticity of this Sealing, when being the fluid of high temperature, high pressure in the tankage, fluid enters in the elastic packing ring inner surface cambridge ring groove, hydrodynamic pressure is delivered on the upper and lower ring tooth internal surface of elastic sealing ring, the corresponding upper and lower flange facing of upper and lower ring teeth directional is tightly pushed, pressure is big more, and sealing effect is good more.When in the tankage being that the fluid of low temperature, low pressure or normal temperature, nothing are pressed, during no liquid, relying on the elastic force of spring self that upper and lower ring tooth of elastic sealing ring and upper and lower flange are fitted closely, the loss of elasticity phenomenon can not appear, can not therefore produce leakage.
Four, description of drawings:
Fig. 1 is the structural representation of Sealing in the utility model;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the structural representation of flange in the utility model;
Fig. 4 is the structural representation that Sealing and flange are used in the utility model.
Among the figure: 5 times rings of ring tooth tooth, 6 upper flanges, 7 lower flanges, 8 toroidal cavities on 1 elastic sealing ring, 2 springs, 3 annular grooves 4
Five, embodiment:
In conjunction with Fig. 1, shown in Figure 2, this shock-resistant resistant to elevated temperatures elastomer seal constitutes by adding shock mount 2 in the elastic sealing ring 1, elastic sealing ring 1 internal surface has wedge shape annular groove 3, for being made by high temperature resistant, high pressure, acidproof, corrosion resistant silica gel composite, it also can be high temperature resistant by fluorine glued compound material and other, high pressure, acidproof, corrosion resistant composite are made.The top of spring 2 is positioned at the bottom of the annular groove 3 of elastic sealing ring 1, and the two ends, bottom extend to going up ring tooth 4, encircling the top of tooth 5 down of elastic sealing ring 1 respectively, and truncation surface is compass shaped.
As shown in Figure 3, the flange that the Sealing in a kind of and the such scheme is used by being bolted together behind upper flange 6,7 pairs of dresses of lower flange, forms the toroidal cavity 8 of placing elastic sealing ring 1 behind upper flange 6,7 pairs of dresses of lower flange.
As shown in Figure 4, when Sealing and flange are used in the utility model, elastic sealing ring 1 is placed in the toroidal cavity 8 of upper flange 6, lower flange 7 formation, tight with bolt, when being the fluid of high temperature, high pressure in the tankage, the pressure of fluid acts on going up ring tooth 4, encircling the internal surface of tooth 5 down of elastic sealing ring 1, make ring tooth 4, encircle tooth 5 down and tightly push to corresponding upper flange 6, lower flange 7 sealing surfaces, make elastic sealing ring 1 combine closelyr with upper flange 6, lower flange 7, sealing effect is very good; When being the fluid of low temperature, low pressure in the tankage, rely on the elastic force of spring 2 self still can make going up ring tooth 4, encircling tooth 5 down and fit closely of elastic sealing ring 1 with upper flange 6, lower flange 7, the loss of elasticity phenomenon can not appear, and can not therefore produce and leak.In addition, because elastic sealing ring 1 is high temperature resistant, high pressure, acidproof silica gel composite, make high temperature resistant, high pressure resistant, the acidproof performance of the utility model relatively good, long service life can be used repeatedly.Certainly, the utility model still can use for pressure, temperature-resistant environment, and sealing effect is better.
