Description
技术领域 technical field
本实用新型涉及一种O型密封圈，属于密封技术领域。 The utility model relates to an O-shaped sealing ring, which belongs to the technical field of sealing.
背景技术 Background technique
O型密封圈一种常见的橡胶密封圈，除静态密封外还常用于动态密封，如旋转泵的轴和液压缸活塞。现有的O型圈在动态密封中经常出现密封面磨损造成密封失效和O型圈发生周向扭曲造成泄漏，使用寿命较短，报废率高，存在不足。 O-ring is a common rubber sealing ring, in addition to static sealing, it is also commonly used for dynamic sealing, such as the shaft of a rotary pump and the piston of a hydraulic cylinder. The existing O-ring often suffers from sealing surface wear during dynamic sealing, resulting in seal failure and circumferential distortion of the O-ring, resulting in leakage. The service life is short, and the scrap rate is high, so there are deficiencies.
实用新型内容 Utility model content
为解决上述问题，本实用新型提出了一种O密封型圈，具有多重密封面和防周向扭曲作用。 In order to solve the above problems, the utility model proposes an O-seal type ring, which has multiple sealing surfaces and anti-circumferential distortion.
本实用新型采用以下技术方案实现： The utility model adopts the following technical solutions to realize:
一种O型密封圈，包括截面呈椭圆形的密封圈本体及设置在密封圈本体内的梭形金属芯，所述密封圈本体具有内密封面和外密封面，所述内密封面和所述外密封面上下两侧均对称设有辅助密封唇，所述辅助密封唇与所述密封圈本体一体成型。 An O-shaped sealing ring, comprising a sealing ring body with an elliptical cross-section and a shuttle-shaped metal core arranged in the sealing ring body, the sealing ring body has an inner sealing surface and an outer sealing surface, and the inner sealing surface and the outer sealing surface The upper and lower sides of the sealing surface are symmetrically provided with auxiliary sealing lips, and the auxiliary sealing lips are integrally formed with the sealing ring body.
进一步地，所述密封圈本体及所述辅助密封唇均包覆有耐磨涂层。 Further, both the sealing ring body and the auxiliary sealing lip are coated with a wear-resistant coating.
有益效果：与现有技术相比，本实用新型的O型密封圈通过设置辅助密封唇和梭形金属芯，使得具有多重密封面，且在周向旋转运动和轴向往复运动时不易扭曲，密封效果好，使用寿命长。 Beneficial effects: compared with the prior art, the O-ring of the utility model has multiple sealing surfaces by setting the auxiliary sealing lip and the shuttle-shaped metal core, and is not easily distorted during circumferential rotation and axial reciprocation, Good sealing effect and long service life.
