Abstract
The utility model discloses a sealing gasket and a sealing assembly comprising the same. The gasket is provided with a through hole which consists of a frustum-shaped space and a cylindrical space, wherein the lower bottom surface of the frustum-shaped space is overlapped with the upper surface of the cylindrical space; the diameter of the lower bottom surface of the frustum-shaped space is greater than that of the upper bottom surface of the frustum-shaped space; and the diameter of the upper bottom surface of the frustum-shaped space is equal to that of a bolt. According to the matching between the sealing gasket and an elastic sealing ring, a friction force between the sealing ring and a sealing surface can be increased, so that the sealing property is improved.
Description
Technical field
The utility model relates to the seal arrangement technical field, particularly a kind of seal washer and contain the black box of sealing packing ring.
Background technique
The installation of coal pulverizer shell liner is with bolt shell liner to be fixed on the coal pulverizer cylinder inboard wall, and the fastening performance of seal ring and seal washer directly has influence on the firm performance of liner plate installation and the sealing of coal pulverizer cylindrical shell.In the existing technology, when shell liner was installed, Sealing adopted annular seal circle and corresponding seal washer stack combinations to use; Seal ring directly contacts with the coal pulverizer cylinder body outer wall, and seal washer contacts with nut, after the bolton; Seal ring receives the longitudinal pressure of bolt, and seal ring is laterally of no force, use a period of time after; Vertically lateral expansion possibly take place and damage in the seal ring of pressurized; Reduced the fastening performance of bolt, reduced the frictional force of seal ring and barrel wall, thereby the sealability of seal ring is descended.
The model utility content
The purpose of the utility model is to overcome above shortcoming, and a kind of frictional force that can increase seal ring and sealing surface is provided, thereby improves the seal washer of sealability and contain the black box of sealing packing ring.
The technological scheme of the utility model is:
A kind of seal washer; Said packing ring is provided with a through hole; Said through hole is made up of a frustoconic shape space and a cylindrical space; The bottom surface in said frustoconic shape space overlaps with the upper surface of said cylindrical space, and the diameter of the bottom surface in said frustoconic shape space is greater than the diameter of the upper bottom surface in said frustoconic shape space, and the diameter of the upper bottom surface in said frustoconic shape space is suitable with the diameter of bolt.
Further, be provided with second cylindrical space between the upper bottom surface in the frustoconic shape space of said through hole and the upper surface of said seal washer, the bottom surface of said second cylindrical space overlaps with the upper bottom surface in said frustoconic shape space.
A kind of black box that contains above-mentioned seal washer; Comprise seal washer and elastic seal ring; The frustoconic shape space of said seal washer through hole and the cylindrical space that is connected with frustoconic shape space bottom surface partly are combined with elastic seal ring, and the center hole of said elastic seal ring overlaps with the frustoconic shape space upper bottom surface of said seal washer through hole.
The seal washer that the utility model provides and contain the black box of sealing packing ring has the following advantages:
1, good seal performance.The through hole of seal washer is made up of a frustoconic shape space and a cylindrical space; The bottom surface in frustoconic shape space overlaps with the upper surface of said cylindrical space; The diameter of the bottom surface in frustoconic shape space is greater than the diameter of the upper bottom surface in frustoconic shape space; The diameter of the upper bottom surface in frustoconic shape space is suitable with the diameter of bolt, and the profile of the elastic seal ring that cooperates with it is made up of a round platform and a cylindrical body, and the area of contact of elastic seal ring and seal washer increases; The seal ring difficult drop-off, thus tightness improved.
Cooperate after the elastic seal ring clamping bolt, elastic seal ring pressurized lateral expansion in the through hole of seal washer; Contact with the inwall of seal washer and to produce squeezing action, the inwall of seal washer makes elastic seal ring more fastening with cooperating of seal washer from laterally, vertically elastic seal ring is applied reaction force; The elastic seal ring difficult drop-off; The tightness of bolt is better, and the lateral expansion of elastic seal ring, and the area of contact of elastic seal ring and sealing surface is increased; Thereby increased the frictional force of seal ring and sealing surface, improved sealability.
2, prolong the working life of elastic seal ring.Elastic seal ring cooperates with seal washer, is coated on seal washer inside, and it is little to be affected by the external environment, and avoids destroying because of the longitudinal shear effect that receives packing ring, thereby has prolonged the working life of seal ring.
On the frustoconic shape space upper bottom surface of seal washer through hole cylindrical hole is set; During bolton; Nut contacts with the surface of seal washer, has avoided nut directly to contact with elastic seal ring and makes elastic seal ring wearing and tearing, has further prolonged the working life of elastic seal ring.
