目前,氧气乙炔旁通阀大多数用普通1/2 ″的水阀或汽阀代用,阀线不甚耐用,阀杆填料容易失效,导致泄漏严重,造成极大浪费且很不安全。为了解决这一矛盾,经反复试验,已试制出一种具有结构简单、工作可靠、修理方便和价格便宜的“气密阀”。一般单位均可自制。气密阀(附图)共由八个部件组成。阀体有进出两个通导,由阀芯5上下控制启闭。阀芯下端面嵌有一块胶木片或尼龙片,以保证阀
At present, oxygen acetylene bypass valve with most common 1/2 “valve or steam valve substitution, valve line is not durable, stem packing easily failure, resulting in serious leakage, resulting in a great waste and very unsafe.In order to solve This contradiction, after repeated tests, has been tried out with a simple structure, reliable, easy to repair and cheap ”gas-tight valve." General units are available.Airtight valve (with photos) consists of eight components The valve body has two pass-through, open and close control by the valve spool 5. The lower end of the spool is embedded with a piece of plastic or nylon sheet to ensure that the valve
