Abstract
The utility model discloses a novel reinforced-plastic sealing element comprising an upper sealing layer and a lower sealing layer. A plurality of shallow grooves are reserved on one side of the lower sealing layer, and another groove with a U-shaped section is reserved on the other side of the lower sealing layer. A plurality of shallow projections arranged on the surface of the upper sealing layer can fit with the shallow grooves of the lower sealing layer. According to characteristics of a concave structure of sealing rings, air inside the concave structure can be exhausted entirely after the sealing rings are pressed; besides, according to the principle of pressure atmosphere, connection and sealing property of the sealing rings can be enhanced to reduce happenings of air leakage, water leakage and oil leakage and the like; and an arch-shaped spring piece is arranged inside the U-shaped groove to guarantee the sealing effect of a side shaft. By the aid of the remarkable advantages of good heat resistance, insulation stability and rub resistance of reinforced-plastic materials, the novel reinforced-plastic sealing element is simple in structure, convenient to manufacture, good in the sealing effect and long in service life.
Description
Technical field
The utility model belongs to seal arrangement, especially relates to a kind of novel enhanced plastic seal.
Background technique
The hydraulic pressure of various machineries or pressure system all be unable to do without Sealing, as O type circle, and U type circle etc.The general Sealing of making of rubber is because hardness and strength deficiency even adopt metal or fiber and other material to be strengthened, also are difficult to use for a long time under harsh conditions.Much higher (Young's modulus of ordinary rubber is 0.2～l0MPa) and the Young's modulus of reinforced plastic Sealing is than rubber or other elastomers, can be up to hundreds of MPa, the reinforced plastic hardness range is very wide, be low to moderate the following low modulus rubber of Shao Al0, high high impact-resistant elastic material to Shao D85, and it is wear-resisting, oil resistance is special good, also can be used as high pressure sealing even strengthen without framework material, high-quality reinforced plastic material in addition can be in the hydraulic system of 50～70MPa proper functioning.
Summary of the invention
The purpose of this utility model has been to propose a kind of Sealing of being made by reinforced plastic material fully, and it is simple in structure, and is easy to make, has stability and wear resistance preferably, good sealing effect.
The technical solution of the utility model is: a kind of novel enhanced plastic seal, it is characterized in that: comprise sealing upper strata and sealing lower floor, seal laminated down a plurality of shallow grooves that have, another side has the cross section U-shaped groove, the sealing upper surface is provided with a plurality of shallow projectioies, in the U-shaped groove arcuate bombing leaf is housed, sealing lower floor axle side has semi-circular recesses.
In the utility model, the sealing upper strata is by a plurality of shallow projectioies, can agree with mutually with the shallow grooves of sealing lower floor, this structure can drain the air of concave structure inside after being stressed, utilize atmospheric principle, can strengthen that seal ring connects and sealability, thereby reduce to produce gas leakage, leak, the generation of situation such as leakage of oil; Sealing lower floor axle side has semi-circular recesses, is convenient to sealing, and arcuate bombing leaf provides radial force for Sealing, makes between Sealing and the axle and can fit tightly, and makes Sealing have better sealing effect.
