marlboro是什么意思>能飞英语摘要：An automatic drain system is provided for rervoirs ud to accumulate water, condensables, and other foreign materials which may be prent in pneumatic systems and the like. This drain system is associated with a rervoir wherein the contaminants are accumulated and is operated by a float within this rervoir. The principal operating items of the drain system are a pair of magnetically coupled magnets, one positioned within the float and the other within a valve plug of a pilot valve. The magnets normally have opposite polarities whereby the float, in its lowest position and as it ris within the rervoir, caus the valve plug to be maintained against the pilot valve at. A parate pneumatic system attached to this pilot valve maintains a drain valve operator in a condition such that the drain valve from the rervoir is clod while the pilot valve components are in contact. When the float reaches its uppermost position, the magnet therein brings about an effective reversal of the polarity of the magnet in the valve plug causing the valve plug to be moved away from the pilot valve at. When this occurs, the drain valve operator is moved in a direction such that the drain valve is rapidly opened permitting the complete draining of any material accumulated in the rervoir. When the float reaches its most downward position, the polarity of the magnet within the pilot valve plug is again effectively reverd and the pilot valve is clod to again clo the
