Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element described by the phrase "comprising a. -" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
Please refer to fig. 1-2, which illustrate an embodiment of the present invention.
A low-stress efficient sealing washer comprises a sealing washer body 1, wherein the upper surface and the lower surface of the sealing washer body 1 are both convex cambered surface sealing surfaces 1-1, and the sealing performance of a sealing washer is improved. The sealing gasket body 1 is made of rubber or flexible graphite material.
An inner steel belt ring 2 is arranged on the inner side of the sealing gasket body 1 in a surrounding mode, an inner limiting ring 3 is arranged on the inner side of the inner steel belt ring 2, an outer steel belt ring 4 is arranged on the outer side of the sealing gasket body 1 in a surrounding mode, and an outer limiting ring 5 is arranged on the outer side of the outer steel belt ring 4. Interior steel band ring 2 and outer steel band ring 4 are surrounded range upon range of by multilayer thin steel band and form, the cross section of thin steel band is half circular structure, interior steel band ring 2 pushes up on 1 inboard round surface of gasket body toward the convex circular arc surface in the outside, outer steel band ring 4 pushes up on 1 outside round surface of gasket body toward the convex circular arc inboard surface in the inboard. This structure can realize carrying out elastic support inside and outside the sealed body that fills up, when guaranteeing sealing performance, can effectively prevent sealed pad deformation.
The sealing gasket comprises a sealing gasket body 1 and is characterized in that an inner mounting groove 1-2 used for being matched with an inner steel belt ring 2 to mount the inner steel belt ring is formed in the inner circular surface of the sealing gasket body 1, and an outer mounting groove 1-3 used for being matched with an outer steel belt ring 4 to mount the outer steel belt ring is formed in the outer circular surface of the sealing gasket body 1. The inner steel belt and the outer steel belt are annularly wrapped in the mounting groove by the structure, so that the components are prevented from being scratched in the use process.
The thickness of the inner limiting ring 3 is smaller than that of the inner mounting groove 1-2, the outer side face of the inner limiting ring 3, which is in contact with the inner steel belt ring 2, is an inner extrusion arc surface 3-1, the thickness of the outer limiting ring 5 is smaller than that of the outer mounting groove 1-3, and the inner side face of the outer limiting ring 5, which is in contact with the outer steel belt ring 4, is an outer extrusion arc surface 5-1. The structure is used for ensuring that the limiting ring does not influence the exertion of the elastic action of the steel belt ring under the limiting action of the limiting ring on the steel belt ring.
