CS-G602 金属空心O形圈是由一个空心金属圆环组成,内部填充惰性气体,外圈一般由合金材料制成。该密封圈独特的材质能实现其它密封件不能满足的要求。垫片独特的结构能实现其它通用垫片不能满足的要求,在高温、高压及超真空的设备及装置中,只需较低的预紧力,即使所需密封的地方较窄小或形状有些特殊,它都能随之而改变自身的形状,有效地起到密封。它尤其适合于一些结构较紧凑,密封要求较高的设备及装置中。如果需要,金属O型圈的表面可进行的特殊的处理。
安装前,应仔细检查并清理密封槽表面,不允许有辐射状,交叉状划伤,压痕和其他附着物等。一般情况下,在自由状态下预压扁。O型圈槽的外径要比金属槽的外径要大0.55毫米。槽的内径要比金属O型圈的内径小0.44毫米,为进一步增强金属O型圈的密封性能。可以在密封圈的外进行表面渡金、银、F4。
CS-G602 Metal hollow O-ring
It consists of a hollow metal ring filled with inert gas and generally made of alloy material.The unique material of the sealing ring can meet the requirements that other seals cannot meet.The unique structure of gaskets can meet the requirements of other universal gaskets,In high-temperature, high-pressure and ultra-vacuum equipment and devices, only a lower pretightening force is required, even if the required sealing place is narrower or has some special shape, it can change its shape and effectively seal.It is especially suitable for some compact and high sealing equipments and devices.The surface of the metal o-ring can be specially treated if required.
