Description
Technical field
The present invention relates to field of rubber materials, is exactly a kind of O type circle that utilizes the fine regenerated rubber of fourth to produce.
Background technology
O RunddichtringO O type circle (O-rings) is that a kind of cross section is circular rubber seal, because its cross section is O type, therefore be called O RunddichtringO, is also O type circle.Start to appear in the middle of the 19th century, with it, make at that time the sealing element of steamer cylinder.
O RunddichtringO is applicable to be contained in various mechanical means, in the temperature, pressure of regulation and different liquids and gases medium, under static or kinestate, seals.On lathe, boats and ships, automobile, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, building machinery, mining machinery, petroleum machinery, plastics machinery, agricultural machine and all kinds of instrument, widely applying various types of sealing elements.O RunddichtringO is mainly used in static seal and reciprocating movement sealing.While being used for rotatablely moving sealing, only limit to low speed rotary seal.O RunddichtringO is generally arranged in the groove that cylindrical or inner circle upper section are rectangle and seals.O RunddichtringO still plays excellent sealing, cushioning effect at environment such as oil resistant, soda acid, mill, chemical erosions.Therefore, O RunddichtringO is most popular a kind of sealing member in hydraulic and pneumatic transmission system.
