Description
Technical field
The utility model relates to pneumatic components and parts technical field, particularly relates to a kind of unidirectional circle of pneumatic throttle.
Background technique
Unidirectional circle is as the important sealing component of in pneumatic throttle, mainly play sealing effect, and the inner seal ring of existing unidirectional circle and the thick end of exterior seal ring inadequate, after the frequent movement alive or friction of unidirectional circle, loss can be larger, so the working life of unidirectional circle can receive impact, also can have influence on sealing effect, gas leakage situation occurs.
Model utility content
The purpose of this utility model is the unidirectional circle providing a kind of pneumatic throttle, and it has increase sealing area thus improves sealing effect, improves unidirectional feature of enclosing working life.
For achieving the above object, the utility model adopts following technical proposals:
A kind of unidirectional circle of pneumatic throttle, comprise unidirectional circle main body, described unidirectional circle main body comprises inner seal ring, exterior seal ring, described inner seal ring is buckled in spool, described exterior seal ring and body cavity are fitted, described inner seal ring top is provided with the first thickened sealing ring, and described exterior seal ring side is provided with the second thickened sealing ring.
Wherein, described first thickened sealing ring is buckled in inner seal ring top, and described inner seal ring top offers draw-in groove, is provided with the buckle corresponding with draw-in groove bottom described first thickened sealing ring.
Wherein, described second thickened sealing ring is buckled in exterior seal ring side, and described exterior seal ring side opening is provided with draw-in groove, and described second thickened sealing ring inner side surface is provided with the buckle corresponding with draw-in groove.
Wherein, described first thickened sealing ring, the second thickened sealing ring, draw-in groove, buckle are formed in one structure.
The utility model beneficial effect: the utility model comprises unidirectional circle main body, described unidirectional circle main body comprises inner seal ring, exterior seal ring, described inner seal ring is buckled in spool, described exterior seal ring and body cavity are fitted, described inner seal ring top is provided with the first thickened sealing ring, described exterior seal ring side is provided with the second thickened sealing ring, after the first thickened sealing ring integrated on the outside snapping of unidirectional circle main body and the second thickened sealing ring, when unidirectional circle work, both add area of contact and reach better sealing effect, and effectively can reduce the wearing and tearing of unidirectional circle, improve working life.
