VCR接头它是一种普遍运用在半导体光电制造行业的密封接头,密封元件采用的金属垫片,通过内、外螺纹互锁来压迫金属垫片,使垫片产生一定的变形,从而达到密封的效果。

The VCR joint is a kind of sealing joint commonly used in semiconductor photoelectric manufacturing industry. The [meta]l gasket used for sealing elements is used to press the [meta]l gasket through the interlock of internal and external threads to produce certain deformation of the gasket, so as to achieve the sealing effect.

那么VCR接头有哪些特点呢?由于VCR接头洁净度高、密封性好,比较适用于对无泄漏要求较高的超高纯净系统、超高真空系统及高压系统。也因为采用了金属密封元件,它的额定工作温度范围比较广,同时VCR接头在安装方面比较容易,也因为它具有较小的拆卸间隙也可以反复拆装。

So what are the characteristics of the VCR connector? Due to its high cleanliness and good tightness, the VCR joint is more suitable for the ultra-high purity system, ultra-high vacuum system and high-pressure system with higher requirements for no leakage. Also because of the use of [meta]l sealing elements, its rated operating temperature range is wide, at the same time, the VCR joint is easier to install, also because it has a small disassembly gap can also be repeatedly disassembled.

下面由小编为大家讲解下VCR接头各组件主要材质,那么它们的材质分别是什么呢?接管、本体和螺母的材质一般为SUS316或SUS316L,垫片的材质一般为SUS316L、镍或铜,不过现在基本都不怎么使用铜垫片了,当然垫片也有镀银和不电镀之分,VCR内螺纹螺母的内螺纹经过镀银处理,以防止磨损。

The following small make up for you to explain the main material of each component of the VCR joint, so what are their materials? SUS316L or SUS316L is the material of connection, [body] and nut. SUS316L, nickel or copper is the material of gasket. However, copper gasket is rarely used nowadays.
