進(jìn)口波紋管截止閥概述：Overview of imported BELLOWS GLOBE valve:
進(jìn)口波紋管截止閥也叫波紋管密封截止閥，通過自動(dòng)滾焊焊接，在流體介質(zhì)和大氣之間形成一個(gè)金屬屏障，確保閥桿零泄漏的設(shè)計(jì)。
Bellows globe valve
Overview of inlet BELLOWS GLOBE valve:
Bellows inlet valve is also known as bellows seal globe valve, through automatic roll welding, in the fluid medium and the atmosphere to form a metal barrier to ensure the design of the valve stem leakage
進(jìn)口波紋管截止閥內(nèi)部采用波紋管結(jié)構(gòu)，不銹鋼的波紋管下端焊接在閥桿上，以防止工藝流體浸蝕閥桿。另一端置于閥體和閥蓋之間構(gòu)成靜密封。采用雙重的密封設(shè)計(jì)若波紋管失效閥桿填料也會(huì)避免泄漏，波紋管焊于閥桿保持穩(wěn)定的運(yùn)行性能，避免由于閥塞振動(dòng)引起閥桿振動(dòng)。適用于蒸汽、易燃、易爆、導(dǎo)熱油、高純度、有毒等介質(zhì)的管路上。
Bellows globe valve with bellows structure, whose lower end is welded on the stem of stainless steel corrugated pipe, to prevent the erosion process fluid stem. The other end is arranged between the valve body and the valve cover to form a static seal. The use of double seal design bellows bellows valve stem packing will also avoid leakage, bellows welded to the stem to maintain a stable operating performance, to avoid the valve plug vibration caused by stem vibration. Most suitable for steam, flammable, explosive, heat conducting oil, high purity, toxic and other media on the pipeline.
