Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of conductor equipment sealing, in particular to a sealing component. Background Art
[0002] Sealing component products are used to be installed in the ports of conductor equipment to seal the ports of conductor equipment. In existing sealing component products, elastic seals are basically designed with dovetail groove assembly. During the assembly process, dust particles are easily caught on the assembly surface and brought into the conductor equipment. The conductor equipment has very high requirements for cleanliness. The entrained particles falling into the conductor equipment can easily cause abnormal operation of the conductor equipment. In addition, when the assembled elastic seal is subjected to force, it is easy to be twisted and rubbed against the edge of the dovetail groove, causing wear, which in turn affects its sealing performance.

[0024] Reference Figure 1-6The utility model provides a sealing component, comprising: a metal substrate 1 and an elastic sealing member 2, wherein: the elastic sealing member 2 is made of perfluoroelastomer.
[0025] The elastic seal 2 has a connecting surface 21 which is attached and fixed to the metal substrate 1 to ensure that there is no gap at the assembly surfaces of the two and that the elastic seal 2 cannot twist, thereby solving the problem of dust on the assembly surface where the elastic seal 2 contacts the metal substrate 1 and the twisting of the elastic seal 2.
[0026] The connection surface 21 is attached to the surface of the metal substrate 1. Figure 1-3 Or, a groove is pre-set on the metal substrate 1, and the connecting surface 21 is attached to the inner wall of the groove on the metal substrate 1, as shown Figure 4-6 shown.
[0027] The elastic seal 2 also has an outer contour surface 22 that is higher than the surface of the metal substrate 1 and connected to the connection surface 21. A plane 23 is provided at the connection between the outer contour surface 22 and the connection surface 21, and when the connection surface 21 is attached to the inner wall of the groove, the area of the metal substrate 1 around the connection surface 21 is in the same plane as the plane 23. Since when the connection surface 21 is on the surface of the metal substrate 1, the outer contour surface 22 and the plane 23 are not in contact with the metal substrate 1, so there will be no wear problem; when the connection surface 21 is on the inner wall of the groove, the outer contour surface 22 is not in contact with the metal substrate 1, and the area of the metal substrate 1 around the connection surface 21 is in the same plane as the plane 23, so there will be no wear problem.
[0028] As can be seen from the above, the utility model effectively solves the problem of dust on the assembly surface of the elastic seal 2 and the metal substrate 1, and the torsion and wear of the elastic seal 2, and effectively ensures the sealing performance of the sealing assembly.
[0029] In a further embodiment, when the connection surface 21 is attached to the surface of the metal substrate 1, the plane 23 is perpendicular to the connection surface 21. The processing method is: when the elastic seal 2 is connected to the metal substrate 1 and the connection surface 21 is attached to the surface of the metal substrate 1, the excess part of the elastic seal 2 is cut along the direction perpendicular to the connection surface 21 to form the plane 23 at the cut. It can be seen that this structural design is easy to process and shape.
[0030] In a further embodiment, when the plane 23 is perpendicular to the connecting surface 21, the metal substrate 1 has an interface 11, and the interface 11 is located below 23 and in the same plane as the plane 23. During processing, when the elastic seal 2 is connected to the metal substrate 1 and the connecting surface 21 is on the surface of the metal substrate 1, the redundant part of the elastic seal 2 is cut along the edge of the connecting surface 21. During the cutting process, the interface 11 guides and gives way to the cutter to ensure that the cut part is completely separated from the elastic seal 2 and the cut surface is flat.
[0031] Specifically, when the plane 23 is perpendicular to the connection surface 21 , the area where the metal substrate 1 is attached to the connection surface 21 is higher than the surrounding area, so as to form an interface 11 on the periphery of the connection surface 21 that is in the same plane as the plane 23 .
[0032] Furthermore, the flatness of the plane 23 is 0.04 mm to 0.09 mm.
[0033] In a further embodiment, when the plane 23 is perpendicular to the connection surface 21, the outer contour surface 22 has an extension surface 221 arranged opposite to the connection surface 21, and the extension surface 221 is connected to the plane 23. Since the thickness of the elastic sealing member 2 at the extension surface 221 is much smaller than its thickness at the outer contour surface 22, the connection strength between the connection surface 21 and the metal substrate 1 can be effectively guaranteed.
[0034] In a further embodiment, when the connecting surface 21 is attached to the inner wall of the groove, a concave surface 24 that is recessed toward the connecting surface 21 is provided at the junction of the outer contour surface 22 and the plane 23. The design of the concave surface 24 enables the elastic seal 2 to form a buffer space between its outer contour surface 22 and its plane 23. When the elastic seal 2 is under pressure, the buffer space can effectively weaken the pressure on the connecting surface 21, thereby ensuring the connection strength between the connecting surface 21 and the metal substrate 1.
[0035] Specifically: the lower concave surface 24 is an arc-shaped surface.
[0036] In a further embodiment, the elastic seal 2 is connected to the metal substrate 1 by a vulcanization process and forms a connection surface 21 at the connection point that is bonded and fixed to the metal substrate 1. The elastic seal 2 is bonded to the metal substrate 1 by a vulcanization process, and this structural bonding and fixing method makes the bond between the two stronger.
[0037] Furthermore, when the elastic seal 2 is connected to the metal substrate 1 and the connection surface 21 is on the surface of the metal substrate 1, the cutter moves downward from above the connection surface 21 and along the edge of the connection surface 21 to cut off the excess portion of the elastic seal 2 to form a plane 23 at the cut.
[0038] In a further embodiment, an adhesive layer is provided at the joint between the connection surface 21 and the metal substrate 1 to further enhance the connection strength between the connection surface 21 and the metal substrate 1 .
[0039] In a further embodiment, the elastic sealing member 2 is a closed annular structural member, and planes 23 are provided on the inner side and the outer side of the outer contour surface 22 thereof.
[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
