Abstract
The utility model relates to the sealing of a kind of super-pressure Novel static, it is applicable to coal-mine hydraulic support column and jack, it comprises: sealing top, seal side, sealing surface and sealed bottom, the sealing top of sealing surface both sides is designed to inclined-plane respectively, and seal side place is lower than groove, sealing surface adopts small arc-shaped mechanism, and sealed bottom is circular arc arch; The utility model adopts the seal of polyurethane material, and the sealing effectiveness of seal is more excellent.The high rigidity of polyurethane material, makes it not need, with back-up ring, just to have very high resistance to compression and anti-extrusion ability.Adopt arc structure bottom seal, enhance the resilience of seal, sealing property is more excellent.
Description
One, technical field
The utility model relates to a kind of super-pressure Novel static sealing of polyurethane turning, is applicable to drive hydraulic support.
Two, background technology
Original piston and fairlead static seal, the back-up ring that each producer all have employed rubber o-ring and polytetrafluoroethylene (PTFE) combines, in use, its sealing effectiveness is not very desirable, often there is the problem of leakage, reduce the efficiency of support. and present maintaining support gets more and more, due to the change of size in oil cylinder maintenance process, cause sealed product nonstandardized technique, due to the operational characteristic that conventional seals product uses mould to produce, make it when the production of nonstandard product, a large amount of moulds must be made, add manufacturer's cost.
Three, the content of utility model
The purpose of this utility model is for existing static seal Problems existing, provides a kind of novel polyurethane turning seal a kind of super-pressure Novel static sealing.
The new technical scheme that the utility model adopts is achieved in that a kind of polyurethane turning type super-pressure Novel static seals, it comprises: sealing top, seal side, sealing surface and sealed bottom, the sealing top of sealing surface both sides is designed to inclined-plane respectively, seal side place is lower than groove, and sealing surface adopts small arc-shaped mechanism, and sealed bottom is circular arc arch.
The utility model static seal adopts polyurethane material turning to form, and due to the change of sealing member material and structure, makes the sealing effectiveness of seal more excellent, its structure is simply easy to processing, and adopt machining center to cut to form, avoid the making of mould, decrease production cost.
The utility model is relative to product structure before this, and its sealability has qualitative leap, and service life extends.
Four, accompanying drawing explanation
Accompanying drawing 1 is the utility model static seal profile.
Accompanying drawing 2 is the utility model static seal sectional view.
Description of reference numerals:
Sealing top 1, seal side 2, sealing surface 3, sealed bottom.
Five, detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
With reference to accompanying drawing, the utility model provides a kind of polyurethane turning type super-pressure Novel static to seal, it comprises: sealing top 1, seal side 2, sealing surface 3, and sealed bottom 4, the sealing top 1 of sealing surface 3 both sides is designed to inclined-plane respectively, seal side 2 place is lower than groove, and sealing surface 3 adopts small arc-shaped mechanism, and sealed bottom 4 is circular arc arch.
The utility model is designed to inclined-plane due to sealing top 1 place, makes seal side 2 place lower than groove, protects sealing ring and can not damage when mounted.Sealing surface 3 place adopts small arc-shaped mechanism, adds the effect of the circular arc arched edge at sealed bottom 4 place, makes its sealing ring have better elasticity, is convenient to install, and can strengthen the decrement of seal, improves the sealability of seal.
The utility model relates to the sealing of a kind of super-pressure Novel static, and it is applicable to coal-mine hydraulic support column and jack, and it, relative to static seal before this, has all done new improvement at material and configuration aspects; Adopt the seal of polyurethane material, the sealing effectiveness of seal is more excellent.The high rigidity of polyurethane material, makes it not need, with back-up ring, just to have very high resistance to compression and anti-extrusion ability.Adopt arc structure bottom seal, enhance the resilience of seal, sealing property is more excellent.
