一、简介：
CS46H membrane-type vapor drain valve (steam pressure balance type) is currently the most widely used advanced energy-saving drain valve in the world. The membrane-type vapor drain valve is very sensitive in response; when working, high-temperature condensate is stored in front of the valve, with no steam leakage, and the energy-saving effect is remarkable. The advantages of the membrane-type vapor drain valve are: automatic air exhaust, small volume, frost-resistant, and can be installed in any position; convenient maintenance, can be inspected, repaired and parts replaced on the pipeline; maximum back pressure rate ≤80%, the membrane is sturdy, and has a long service life. The CS46H membrane-type vapor drain valve is suitable for steam main pipelines, steam tracing pipelines, instrument tracing and steam-water blocking and drainage of small heating equipment, with a wide range of applications.
二、产品特点：
1、It operates cyclically with fixed subcooling within the pressure range.
2、Excellent drainage capacity, resistant to superheated steam and water hammer.
3、The temperature-sensing element has strong corrosion resistance, making this valve long-lasting and durable.
4、The valve is equipped with a membrane, available in single, double, or multiple groups; suitable for high-discharge occasions.
5、The body has two structures: carbon steel and stainless steel; small and lightweight, with good vertical installation effect, and can also be installed at any angle.
三、工作原理：
1、When the device starts, air enters the drain valve, and the valve core is in the open position at low temperature.
2、Immediately after, condensate enters the drain valve; at low temperature, the temperature-sensing liquid inside the membrane element remains in a condensed state, and the valve core is fully open, quickly discharging the condensate.
3、When condensate enters the drain valve, the temperature-sensing liquid inside the membrane element begins to evaporate and expand as the temperature rises; the increased internal pressure causes the diaphragm to drive the valve core to move toward the closed direction, and the valve core fully closes before the temperature reaches the saturation temperature.
4、After the hot condensate stored in the valve slowly cools down, the diaphragm contracts due to reduced internal pressure, driving the valve core to open and continue discharging condensate. Since hot condensate is always stored in front of the valve, steam-water separation is formed with no steam leakage. CS46H membrane-type vapor drain valve external connection dimensions:
