氦質(zhì)譜檢漏：API 602 MSS SP-117
應(yīng)用：適用于有毒有害高危介質(zhì)工況，如干氯氣，氨氣等。
設(shè)計(jì)特點(diǎn)：
1：零泄漏密封：
主密封：波紋管組件密封， 采用內(nèi)藏式免沖刷設(shè)計(jì)，通過(guò)液壓成形，多層結(jié)構(gòu)，可保證最大程度的壽命延長(zhǎng)，在壓力2.5MPa下伸縮（即開(kāi)關(guān)）可達(dá)10000次。
輔助密封：非金屬填料，使用帶緩蝕劑的編織填料，更增加了可靠性、安全性以及耐高溫性，提供一個(gè)無(wú)需維護(hù)的條件。
2： 內(nèi)限位裝置，增加閥桿的上限位，保護(hù)閥門(mén)的使用安全，有效的保護(hù)波紋管的彈性變量，大大提高使用壽命。
3：密封面由硬質(zhì)合金堆焊而成，隔斷性?xún)?yōu)異
4：波紋管選用特材哈氏合金HC.276
Application: Suitable for toxic and hazardous media conditions,
such as dry chlorine, ammonia, etc.
Design features：
1: Zero leakage seal.
Main seal: Bellows assembly seal, with built-in flush-free design,by hydraulic forming, multi-layer
structure, can ensure maximum life extension, expansion and contraction (open/close)
up to 10,000 times
at a pressure of 2.5 MPa.
Auxiliary seal: non-metallic packing, using braided packing with corrosion inhibitor, for added reliability, safety
and resistance to high temperatures,
providing a maintenance-free condition.
2: Internal limiting device,Increase the upper limit of the valve stem toprotect the safety of the valve in use,
effectively protecting the elastic variables
of the bellows and greatly increasing the
service life.
3: Sealing surface made of carbide overlay welding, excellent isolation.
4: The bellows is made of special material Hastelloy HC.276.
