VCR接頭它是一種普遍運(yùn)用在半導(dǎo)體光電制造行業(yè)的密封接頭，密封元件采用的金屬墊片，通過內(nèi)、外螺紋互鎖來壓迫金屬墊片，使墊片產(chǎn)生一定的變形，從而達(dá)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接頭有哪些特點(diǎn)呢？由于VCR接頭潔凈度高、密封性好，比較適用于對無泄漏要求較高的超高純凈系統(tǒng)、超高真空系統(tǒng)及高壓系統(tǒng)。也因?yàn)椴捎昧私饘倜芊庠?，它的額定工作溫度范圍比較廣，同時(shí)VCR接頭在安裝方面比較容易，也因?yàn)樗哂休^小的拆卸間隙也可以反復(fù)拆裝。

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.

下面由小編為大家講解下VCR接頭各組件主要材質(zhì)，那么它們的材質(zhì)分別是什么呢？接管、本體和螺母的材質(zhì)一般為SUS316或SUS316L，墊片的材質(zhì)一般為SUS316L、鎳或銅，不過現(xiàn)在基本都不怎么使用銅墊片了，當(dāng)然墊片也有鍍銀和不電鍍之分，VCR內(nèi)螺紋螺母的內(nèi)螺紋經(jīng)過鍍銀處理，以防止磨損。

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.
