Abstract

The utility model belongs to the device that hydropneumatic is sealed, concretely relates to sealing device who combines radial seal and axial seal. The device is including stifled dish, seal part, O appear rubber seal, rubber packing pad and bolt. Stifled dish and the slot department installation O shape rubber seal of seal part through the path axle construction at stifled dish are with the installation that closely cooperates of seal part's path hole, formation radial seal, compress tightly the axial seal that 2 rubber packing pad formed in complex step hole department, has realized radial seal and axial seal's two way seal, better assurance the leakproofness of seal part inner chamber.

Description

A kind of seal arrangement in conjunction with radial seal and axial seal
Technical field
The utility model belongs to the device of a kind of hydropneumatic sealing, is specifically related to a kind of seal arrangement in conjunction with radial seal and axial seal.
Background technique
Existing sealing configuration, comprises radial seal structure and axial seal structure.In current most device, only can be used alone radial seal structure or axial seal structure, sealing means is single, and sealing reliability cannot The Gift of Being the Best You Can Be.
Model utility content
The purpose of this utility model is to provide a kind of seal arrangement in conjunction with radial seal and axial seal, the sealing configuration that it can overcome existing hydraulic pressure airtight is single, from radial or axial single direction sealing, when internal pressure is excessive, can only cannot ensure the defect sealed.
The utility model realizes like this, a kind of seal arrangement in conjunction with radial seal and axial seal, it comprises stifled dish, sealed member, O shape rubber seal, rubber gasket and bolt, wherein, there is an inner chamber sealed member inside, a wallboard there is a step hole, and have the structure of 4 tapped holes, the little journal axle place of stifled dish is with groove, and a structure being threaded the step cover plate of via hole, the groove place of stifled dish is all provided with O shape rubber seal, the top bar diameter holes in hole of the stifled little journal axle of dish and the wallboard of sealed member closely cooperates and installs, form radial seal structure, rubber gasket is arranged on the step hole place of stifled dish, the step cover plate contact rubber gasket of stifled dish, the rubber gasket blocked up between dish and sealed member by bolt presses forms axial seal.
The groove at the little journal axle place of described stifled dish is 2 or more.
The utility model has the advantages that, combine the radial seal structure of O-ring seals and compress the axial seal structure of rubber gasket, adding sealing than one-way sealing structure, also more reliable to the gas liquid sealing effect of higher pressure.
Accompanying drawing explanation
Fig. 1 is a kind of seal arrangement general structure schematic diagram in conjunction with radial seal and axial seal provided by the utility model;
Fig. 2 is a kind of seal arrangement concrete structure schematic diagram in conjunction with radial seal and axial seal provided by the utility model.
In figure, 1 stifled dish, 2 sealed members, 3O shape rubber seal, 4 rubber gaskets, 5 bolts.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail:
As depicted in figs. 1 and 2, a kind of seal arrangement in conjunction with radial seal and axial seal it comprise O shape rubber seal 3,2 rubber gaskets 4,4 bolts 5 of a stifled dish 1, sealed member 2,2 or more.The little journal axle place of stifled dish 1 is with 2 or more grooves, and a structure with the step cover plate of 4 screw thread via holes; There is an inner chamber sealed member 2 inside, a wallboard has a step hole, and has the structure of 4 tapped holes.1 O shape rubber seal 3 is installed at each groove place of stifled dish 1, and the top bar diameter holes in hole of the stifled little journal axle of dish 1 and the wallboard of sealed member 2 closely cooperates and installs, formation radial seal structure.2 rubber gaskets 4 are arranged on the step hole place of stifled dish 1, and the step cover plate of stifled dish 1 contacts 2 rubber gaskets, compress the rubber gasket 4 before stifled dish 1 and sealed member 2, form axial seal by 4 bolts 5.In conjunction with radial seal and axial seal two way sealed, just in the inner chamber of sealed member 2, better sealing can be accomplished after injecting gas or liquid.
