LNG低温密封圈

密封圈使用介绍:


       密封圈安装在沟槽内,弹簧受压,形成向外的张力,促使密封唇紧贴密封沟槽,由于弹簧永久给密封唇提供弹力,能弥补密封壳磨损和配合零件的偏心,由此形成从真空到低压范围内的密封。另外系统压力会辅助弹簧蓄能,压力越大,密封唇与沟槽贴合的越充分,由此形成高压密封。
       密封圈适用于从-200℃到+260℃温度范围内,密封几乎所有的液体、化学制品和气体。
综合了大部分塑料的优越性能,耐冲击、耐高低温、耐磨损、耐化学腐蚀、自身润滑.广泛
应用于矿山、钢铁、冶金、煤炭、电力、石油、纺织、造纸、化工、电气、港口等行业。金
属弹簧有多种形式可供选择,有O 型弹簧,V 型弹簧,U 型弹簧,满足不同运动形式的密
封要求。

The seal ring installed in the groove forms outward tension under spring pressure to bond the sealing lip to the sealing groove and achieves sealing ranging from vacuum to low pressure through the permanent supply of elasticity from the spring to the sealing lip to make up for wear of the seal housing and eccentricity of coordinated parts. In addition, the system pressure will help energy accumulation of the spring to achieve high-pressure sealing since the greater the pressure, the better bonding between the sealing lip and the groove.

The seal rings are applicable in temperature ranging from -200°C to +260°C for sealing of almost all liquids, chemicals and gases.

The seal rings incorporate most of advantages of plastics: resistant to impact, high & low- temperature, wear and chemical corrosion and self-lubricating. They are widely applied in mining, steel, metallurgy, coal, electricity, petroleum, textile, papermaking, chemicals, electricity, ports and other industries. There are various forms of metal springs for your options, including O-shaped springs, V-shaped springs and U-shaped springs to meet sealing requirements of different movement forms.
