What are the types of mechanical drain valves
Mechanical drain valves include free floating ball type, free semi floating ball type, lever floating ball type, inverted bucket type, etc
Free floating ball drain valve:
The structure of the free floating ball drain valve is simple, with only a finely ground stainless steel hollow floating ball as a moving part inside. It is both a float and an opening and closing part, with no vulnerable parts and a long service life. The drain valve is equipped with a Y-series automatic air exhaust device inside, which is very sensitive and can automatically exhaust air, with high working quality.
What are the types of mechanical drain valves
When the equipment starts working, the air in the pipeline is discharged through the Y series automatic air exhaust device. Low temperature condensed water enters the drain valve, the liquid level of condensed water rises, the float rises, the valve opens, and the condensed water is quickly discharged. Steam quickly enters the equipment, and the equipment quickly heats up. The temperature sensing liquid of the Y series automatic air exhaust device expands, and the automatic air exhaust device closes. The drain valve starts working normally, and the float rises and falls with the level of condensed water, blocking steam and draining water. The valve seat of the free floating ball drain valve is always below the liquid level, forming a water seal with no steam leakage and good energy-saving effect* The small working pressure is 0.01Mpa, and it is not affected by temperature and working pressure fluctuations within the range of 0.01Mpa to ≤ usage pressure, with continuous drainage. It can discharge saturated temperature condensed water, with a small subcooling degree of 0 ℃, and there is no water in the heating equipment, which can achieve the best heat transfer efficiency of the heating equipment. The back pressure rate is greater than 85%, making it one of the ideal drain valves for production process heating equipment.
