Abstract
The utility model relates to a sealing gasket which comprises a metal gasket and a rubber sealing gasket, wherein the shape of the metal gasket is the same with that of a sealing surface; a fixing hole is formed in the metal gasket; and the rubber sealing gasket is rightly bonded on the metal gasket. The sealing gasket can realize the sealing function through a simple technology during end surface sealing, simultaneously has good vibration resistance capability, and is applicable to the operating environment with higher liquid pressure.
Description
Technical field
The utility model relates to a kind of gasket seal.
Background technique
At present, in the seal arrangement that acts in most of mechanical systems, generally all be to use rubber sealing.When carrying out end face seal, need fixedly groove or the corner angle of cushion rubber be set at part spare, otherwise cushion rubber is difficult for fixing.The manufacturability of rubber sealing is comparatively complicated like this, the antivibration ability a little less than, the fluid pressure of carrying is lower, sealing effect is not strong.
Summary of the invention
The purpose of this utility model provides a kind of gasket seal, and this pad can utilize simple technology just can realize sealing function when carrying out end face seal, has good antivibration ability simultaneously, and is applicable to the working environment that fluid pressure is higher.
The technical solution of the utility model is: gasket seal comprises metallic shim, rubber gasket, wherein the shape of metallic shim is identical with the sealing surface shape, be provided with fixed hole above, tighten at metallic shim and to be bonded with rubber gasket, described metallic shim is done antirust processing, vulcanize combination after metallic shim and the rubber gasket secure bond, the material of described rubber gasket is oil resistant butadiene-acrylonitrile glue or fluorine rubber.
Metallic shim of the present utility model plays a supportive role, and rubber gasket seals.The utility model has adopted the form of metallic shim and rubber gasket combination, can be used for the end face static seal for screwed pipe joint and plug screw sealing usefulness, prevents the leakage of fluid.The sealing pad is for the one-piece parts of combination, and is easy to loading and unloading, simple in structure.Sealed surface need not to process the groove that usefulness is installed, and directly uses to get final product, and manufacturability is strong.The combined labyrinth and carbon gland pad is subjected to the squeezing action on two sealed planes, and lifting surface area is bigger, and therefore, the fluid pressure that can carry is higher, plays stronger seal action.Metallic shim is provided with fixed hole, installs reliably, can be applicable to vibrate bigger operating conditions.Axial pressing force during connection is little, and the back that works long hours only needs to change a new combined labyrinth and carbon gland pad, and need not repair sealed part, has reduced user cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is usage mode schematic representation of the present utility model.
Embodiment
As shown in Figure 1, gasket seal comprises metallic shim 1, rubber gasket 2, wherein the shape of metallic shim 1 is identical with the sealing surface shape, be provided with fixed hole above, tighten at metallic shim 1 and to be bonded with rubber gasket 2, described metallic shim 1 is done antirust processing, vulcanizes combination after metallic shim 1 and rubber gasket 2 secure bond, and the material of described rubber gasket 2 is oil resistant butadiene-acrylonitrile glue or fluorine rubber.
During use, as shown in Figure 2, the position 3 of carrying out end face seal at needs is outside equipped with gasket seal, and fixes by screw 4, has realized good end face seal function.
Claims (3)
