進(jìn)口波紋管閘閥質(zhì)優(yōu)價(jià)廉德國洛克

一、進(jìn)口波紋管閘閥產(chǎn)品描述：

德國《LOCKE》洛克進(jìn)口波紋管閘閥(Bellows valve)主要用波紋管作為閥桿密封元件的閥門。它常用于對閥桿密封要求嚴(yán)格的場合，如用于高真空的場合和核工業(yè)中。采用波紋管代替普通閥門上的填料函或與填料函并用，可使閥桿部位無泄漏，以防止放射性物質(zhì)或貴重物質(zhì)外漏，或保持高真空。波紋管隨閥桿的升降而伸縮，其最高工作壓力取決于波紋管的耐壓強(qiáng)度和疲勞強(qiáng)度。

The bellows valve imported by Locke in Germany mainly uses bellows as the valve stem sealing element. It is often used in occasions with strict requirements for stem sealing, such as high vacuum occasions and nuclear industry. The use of bellows instead of or in combination with the stuffing box on the common valve can make the valve stem free of leakage, so as to prevent the leakage of radioactive substances or valuable substances, or maintain high vacuum. The bellows expands with the rise and fall of the valve stem, and its maximum working pressure depends on the compressive strength and fatigue strength of the bellows.
