When the equipment is just started, the low-temperature condensate and air enter the valve cavity at the same time. At this time, open the automatic evacuation device to remove the air, so that the low-temperature condensate can enter the valve cavity smoothly. The liquid level of the condensate in the valve cavity will rise immediately, so that the floating ball will rise. Open the valve hole, so that the condensate can be discharged quickly. The steam in front of the equipment will enter the heating equipment quickly, so that the equipment can be heated quickly and heated up. When the steam or the temperature is lower than When the high temperature condensed water enters the valve chamber, the automatic emptying device starts to expand, the automatic air exhausting device is closed, and the drain valve starts to work normally. At this time, the floating ball in the valve chamber will rise and fall with the level of condensate, which can discharge condensate continuously. Because the valve seat hole of the free floating ball type drain valve is always below the condensate level, forming a water seal, the water vapor is naturally separated, and there is no steam leakage during operation. The minimum working pressure of the valve is 0.01Mpa, from 0.01Mpa to the maximum working pressure range, it is not affected by the fluctuation of temperature and working pressure, and can work continuously. Its minimum supercooling degree is about 0 ℃. Because the valve can automatically and continuously remove the condensate, there is no water accumulation in the heating equipment, which can make the heating equipment achieve the ideal heat exchange efficiency. It is one of the ideal drain valves for heating equipment of production process.
