渗碳炉或共渗炉上的滴油器常因针阀损坏而失控。我们采用医用输液滴管和水止(小夹子)来代替。油箱与炉子之间用透明塑料管联接,滴管和止水可装在炉前,也可以装在油箱下面。装水止的地方用一小段胶管代替塑料管。这种方法我们已使用两年多,效果良好,而且价格低廉,更换一个输液滴管仅 Carbide or coke oven drip often lost control due to needle valve damage. We use medical infusion dropper and water stop (small clip) instead. Between the tank and the furnace with a transparent plastic pipe connection, dropper and stop the water can be installed in the furnace, can also be installed in the tank below. Place a small piece of hose instead of a plastic tube. This method we have been using for more than two years, the effect is good, and the price is low, replace only one infusion dropper
