Wherein, at least part of the outer edge of the elastic piece 3 is abutted with the peripheral wall 13 of the annular gasket main body 1, so that the annular gasket main body 1 is deformed along the radial direction under the extrusion action of the elastic piece 3 to be in sealing fit with the component to be sealed. It can be understood that, since the elastic member 3 is located in the annular cavity 2 of the annular gasket main body 1, at least part of the outer edge of the elastic member 3 may abut against the peripheral wall 13 of the annular gasket main body 1, that is, at least part of the outer edge of the elastic member 3 abuts against the inner surface of the peripheral wall 13.
Illustratively, when the gasket is used to seal the upper and lower components, the gasket is placed on the top surface of the lower component, then the upper part is placed on the sealing gasket, the upper part and the lower part are connected together through a fastener and the like, during the connection, the pressure to which the gasket is subjected causes the elastic element 3, which is located inside the annular cavity 2, to deform in a radial direction, in which case, at least part of the outer edge of the elastic member 3 presses the peripheral wall 13 of the annular gasket body 1, the elastic member 3 deforms and is transmitted to the annular gasket body 1 outside the elastic member, since the annular gasket body 1 is deformable, the outer annular gasket body 1 is radially deformed by the component pressure and the pressing action of the elastic member 3, therefore, the annular gasket main body 1 can be well attached to the sealing surfaces of the components, and the sealing effect between the components is improved.
For another example, the gasket is used for flange connection, specifically, the flange includes an upper flange and a lower flange, the upper flange and the lower flange are respectively provided with a plurality of bolt holes, when in connection, the upper flange and the lower flange are sleeved outside the connection surface of two pipelines to be connected, the connection surface is cleaned up first, the gasket is arranged on the connection surface, the bolt holes of the upper flange are aligned with the bolt holes of the lower flange, then the upper flange and the lower flange are fastened together through bolts penetrating through the corresponding bolt holes, the bolts are tightened, in the tightening process, due to the pressure borne by the gasket, the elastic piece 3 located in the annular cavity 2 can be radially deformed, at least part of the outer edge of the elastic piece 3 can extrude the peripheral wall 13 of the annular gasket main body 1, the deformation of the elastic piece 3 is transmitted to the annular gasket main body 1 outside the annular gasket main body 1, and the annular gasket main body 1 outside can be radially deformed under the action of component pressure and the extrusion of the elastic piece 3 Therefore, the annular gasket main body 1 can be well attached to the sealing surfaces of the components, the sealing surfaces are completely covered, and the sealing effect between the components is improved.
wherein, at least partial outer fringe of elastic component 3 and the perisporium 13 butt of annular gasket main part 1, specifically can, the whole outer fringe of elastic component 3 all with the perisporium 13 butt of annular gasket main part 1, like this when elastic component 3 pressurized takes place to warp, can follow and extrude perisporium 13 in the circumference for annular gasket main part 1's deformation is more even, and sealed effect is better. Of course, when the elastic member 3 is not compressed, a part of the outer edge of the elastic member 3 may abut against the peripheral wall 13 of the annular gasket body 1, and a gap may be provided between the other part of the outer edge and the peripheral wall 13 of the annular gasket body 1, and when the elastic member 3 is compressed, a part of the outer edge of the elastic member 3 may press the peripheral wall 13, or when the elastic member 3 is deformed to a certain extent, the entire outer edge of the elastic member 3 may press the peripheral wall 13.
In the sealing gasket provided by the embodiment, the elastic member 3 and the annular gasket body 1 capable of deforming are arranged, the annular top wall 11, the annular bottom wall 12 and the peripheral wall 13 of the annular gasket body 1 jointly enclose the annular cavity 2 capable of accommodating the elastic member 3, and at least part of the outer edge of the elastic member 3 is abutted to the peripheral wall 13, so that after the sealing gasket is installed at an installation position, the elastic member 3 located in the annular cavity 2 is deformed in the radial direction due to the pressure borne by the sealing gasket, at least part of the outer edge of the elastic member 3 extrudes the peripheral wall 3 of the annular gasket body 1, the deformation of the elastic member 3 is transmitted to the annular gasket body 1 outside, and as the annular gasket body 1 can deform, the annular gasket body 1 outside can deform in the radial direction under the action of the component pressure and the extrusion of the elastic member 3, so that the annular gasket body 1 can be well attached to the sealing surface of a component, thereby improving the sealing effect between the parts.
in this embodiment, the elastic element 3 is in particular in an interference fit with the wall of the annular cavity 2. Through making elastic component 3 and 2 interference fit of toroidal cavity, need not to set up extra mounting and can make elastic component 3 stable be in toroidal cavity 2, and can not deviate from toroidal cavity 2, guaranteed seal gasket's normal use. In addition, the elastic part 3 and the annular cavity 2 are in interference fit, so that the elastic part 3 and the annular gasket body 1 are convenient to disassemble, the elastic part 3 or any one of the annular gasket body 1 is damaged, only the damaged elastic part 3 or any one of the annular gasket body 1 needs to be replaced, the whole gasket is prevented from being scrapped, and the cost is saved.
Of course, in other implementations, the elastic member 3 may also be fixed in the annular cavity 2 by a snap or the like, without affecting the normal deformation and elastic recovery of the elastic member 3.
in a possible implementation, the annular gasket body 1 can be made of teflon, so that when the sealing gasket is in use, the plastic deformation performance of the sealing gasket is improved along with the increase of the temperature when the working temperature is high. Under the condition of equal pressure, the deformation capacity is increased along with the increase of the temperature, and the sealing is more facilitated. And the annular gasket body 1 is made of polytetrafluoroethylene, so that the sealing gasket can be used at a sealing position with high requirement on wear resistance.
In another possible implementation, the annular gasket body 1 may also be made of rubber. Under the conditions of low pressure and low wear-resisting requirement, the annular gasket main body 1 can be made of rubber. The rubber is a high-elastic material capable of reversibly deforming, can generate large deformation under the action of small external force, can generate plastic flow during deformation, and can recover the original shape after the external force is removed in the deformation range. The better plastic property ability of the rubber enables the gasket to achieve better sealing effect in the using process.
In this embodiment, the elastic member 3 is specifically a spring, and the elastic member 3 is configured as a spring, so that the manufacturing is convenient and the cost is low. After the sealing gasket is installed, the spring can deform along the radial direction due to the bearing pressure, the deformation of the spring is transmitted to the external annular gasket main body 1, the annular gasket main body 1 also deforms along the radial direction, the sealing gasket can be better attached to and covers a sealing surface, and a better sealing effect is achieved.
Of course, in other embodiments, the elastic member 3 may be an elastic block or the like, as long as it can be deformed by being pressed, can press the peripheral wall 13, and has an elastic restoring force, and the present invention is not limited thereto.
With continued reference to fig. 1, in the present embodiment, the elastic member 3 is embodied as an annular elastic member 3 matching the shape of the annular cavity 2. So the manufacture and the installation are more convenient, and the sealing effect of the sealing gasket is better. The annular elastic piece 3 matched with the annular cavity 2 in shape is arranged in the annular cavity 2, and the elastic piece 3 is pressed to deform and then is transmitted to the external annular gasket main body 1, so that the annular gasket main body 1 is uniformly stressed and deformed in the circumferential direction, a sealing surface is covered by a larger area, and a better sealing effect is achieved. And the manufacturing method of the annular elastic part is mature, and the application requirement can be well met.
Referring to fig. 2, the inner diameter of the elastic member 3 may be smaller than the inner diameter of the annular gasket body 1, which facilitates the installation and removal of the elastic member 3.
Of course, in other implementations, the inner diameter of the elastic member 3 may be made to coincide with the inner diameter of the annular gasket body 1, or may be made smaller than the inner diameter of the annular gasket body 1.
In other implementations, the elastic member 3 may also include at least two sub-elastic members, wherein the at least two sub-elastic members are arranged at intervals along the circumferential direction of the annular cavity 2. Compression of the peripheral wall 13 is also achieved to deform the annular gasket body 1 into sealing engagement with the sealing surfaces of the components.
During specific implementation, the distance between two adjacent bullet linear pieces can be equal, so that the stress and deformation of different positions in the circumferential direction of the whole sealing gasket are uniform. For example, 4 sub-elastic members are arranged at equal intervals along the circumferential direction of the annular gasket main body 1, the sub-elastic members deform under stress, the annular gasket main body 1 deforms uniformly in four directions from four points to extrude the peripheral wall 13 uniformly, and the annular gasket main body is well attached to a sealing surface, so that a good sealing effect is achieved.
For another example, 3 sub-elastic members are arranged at equal intervals along the circumferential direction of the annular gasket main body 1, the sub-elastic members deform under stress, the annular gasket main body 1 deforms by extruding the peripheral wall 13 uniformly from three points, and the annular gasket main body is well attached to a sealing surface, so that a good sealing effect is achieved.
Of course, in other implementations, the distance between two adjacent elastic pieces may not be equal, and the elastic pieces deform in the radial direction after being stressed, and can press the peripheral wall 13; or the sub-elastic member deforms to a certain extent to press the peripheral wall 13 to a greater extent. Although the interval between two adjacent sub-elastic members varies, can make perisporium 13 circumference atress inhomogeneous, as long as can extrude perisporium 13, the sealed face of laminating well reaches better sealed effect can, the utility model discloses not so as the limit.
In this embodiment, the entire outer edge of the elastic member 3 abuts against the peripheral wall 13, so that when the elastic member 3 is just subjected to pressure, the elastic member 3 can effectively press the peripheral wall 13, thereby deforming the annular gasket body 1 to make the sealing faster.
Of course, it is also possible that a gap is provided between part of the outer edge of the elastic member 3 and the peripheral wall 13, and the gap is not more than 3 mm. Like this when elastic component 3 pressurized, when elastic component 3 radially warp to a certain extent, elastic component 3 still can produce the extrusion to perisporium 13 to make annular gasket main part 1 take place radial deformation, and then realize well sealed.
The gap which is not larger than 3mm is formed between the partial outer edge of the elastic part 3 and the peripheral wall 13, so that the elastic part 3 can be transmitted to the external annular gasket main body 1 after being compressed and deformed along the radial direction, or the elastic part 3 deforms to a certain degree, the whole outer edge of the elastic part 3 extrudes the peripheral wall 13, and the good sealing effect cannot be achieved due to too large gap.
In the sealing gasket provided by the embodiment, the elastic member 3 and the annular gasket body 1 capable of deforming are arranged, the annular top wall 11, the annular bottom wall 12 and the peripheral wall 13 of the annular gasket body 1 jointly enclose the annular cavity 2 capable of accommodating the elastic member 3, and at least part of the outer edge of the elastic member 3 is abutted to the peripheral wall 13, so that after the sealing gasket is installed at an installation position, the elastic member 3 located in the annular cavity 2 is deformed in the radial direction due to the pressure borne by the sealing gasket, at least part of the outer edge of the elastic member 3 extrudes the peripheral wall 13 of the annular gasket body 1, the deformation of the elastic member 3 is transmitted to the annular gasket body 1 outside, and as the annular gasket body 1 can deform, the annular gasket body 1 outside can deform in the radial direction under the action of the component pressure and the extrusion of the elastic member 3, so that the annular gasket body 1 can be well attached to the sealing surface of a component, thereby improving the sealing effect between the parts. Based on the above description, the sealing gasket provided by the embodiment can replace a steel ring and graphite sealing method in a certain range, and has the characteristics of economy and easiness in manufacturing.
