进口波纹管截止阀概述：Overview of imported BELLOWS GLOBE valve:

进口波纹管截止阀也叫波纹管密封截止阀，通过自动滚焊焊接，在流体介质和大气之间形成一个金属屏障，确保阀杆零泄漏的设计。

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

进口波纹管截止阀内部采用波纹管结构，不锈钢的波纹管下端焊接在阀杆上，以防止工艺流体浸蚀阀杆。另一端置于阀体和阀盖之间构成静密封。采用双重的密封设计若波纹管失效阀杆填料也会避免泄漏，波纹管焊于阀杆保持稳定的运行性能，避免由于阀塞振动引起阀杆振动。较适用于蒸汽、易燃、易爆、导热油、高纯度、有毒等介质的管路上。

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.
