Function and structural features
High-temperature-and-high-pressure disc-type steam trap valve is used for steam subcritical state of the high temperature and high pressure saturation, main steam pipe and turbine machine.
2.1 .Within working pressure range, there is no need to adjust, energy-saving effect is remarkable. 2.2, strong corrosion-resistance, working is reliable and durable. 2.3, it can quickly exhaust air and condensed water of starting equipment, with large displacement, small gas-leakage rate. 2.4 the internal is equipped with automatic blowdown device, new crown type valve plates, and extremely reliable seal. Steam heat-preservation device, high efficiency and energy-saving.
