The high-temperature and high-pressure boiler drain valve is widely used for continuous throttling control or intermittent discharge of boiler water. It is a specially designed product for the characteristics of high pressure difference, high flow rate, and severe flushing of boiler water discharge conditions. It is divided into four structures: straight through, angle, series, and Y-shaped. The design of the sleeve guided multi-stage pressure reducing structure and the valve seat outlet Venturi tube can effectively control the outlet flow rate, and surface hardening treatment can effectively extend the service life. The standard structure of the blowdown valve for high-temperature and high-pressure boilers is manual control, and pneumatic and electric control can also be selected according to requirements. Pneumatic control can be equipped with accessories such as solenoid valves, pneumatic control valves, and quick discharge valves to achieve rapid cut-off, with cut-off times of 1S, 2S, 3S, 4S, etc.
