The invention discloses a steam drain valve. A shell is sequentially provided with an upper water inlet, a lower water outlet, a self-cleaning filter, a slag-drip opening, a temperature stress and strain piston and a self-lubricating sealing pair from top to bottom. A valve body is provided with a thermoresistive sensor mounting hole. The steam drain valve is reasonable in structure, low in manufacturing and maintenance cost, convenient to maintain and good in filtering effect, the problem that due to the fact that a valve element is blocked by impurities, the drain valve loses efficacy is solved, the service life of the valve body is long, the drained liquid temperature is adjustable, and the drain valve can meet requirements of different condensate draining speeds and requirements. 本发明公开了种蒸汽疏水阀,所述外壳由上到下依次设有上端进水口，下端出水口，自清洗过滤器、排渣口、温度应力应变活塞、自润滑密封副。阀体设有热电阻传感器安装孔。本发明结构合理，制造和维护成本低，检修方便；过滤效果好，解决了因杂质卡塞阀芯使疏水阀失效的问题，阀体的使用寿命长，排液温度可调，可以适应不同凝液排放速度与温度的要求。
