Temperature and pressure reducing device

The utility system is composed of a pressure reducing system, a temperature reducing system, a safety protection device and an automatic control device. Pressure relief system - by the pressure reducing valve and orifice plate, through the automatic control system sampling, calculation, output control actuator to adjust the valve opening to achieve the regulation of steam pressure. Temperature reduction temperature reduction system by water mixing pipes, to adjust the nozzle temperature reducing water flow through the area and water supply mechanism with execution control valve opening size to achieve control steam temperature based on the water spray head force and spring force. Safety protection device, is the direct use of impulse safety device (consisting of the main safety valve and impulse safety valve) or spring safety valve to achieve the two time, when the pressure exceeds the set value, the pressure more than part of the steam discharged into atmosphere, so that the two pressure is kept within the permitted value. Automatic control device with RKG - sign type steam pressure and temperature control device, the new steam through the device; can make two steam parameters maintained at a desired stable value. No Information 1 imported P1 steam pressure is less than or equal to 10MPa, the temperature is not higher than 540 DEG t1;
2 outlet flow Q: temperature and pressure reducing device outlet flow Q change range 99% ~ 10%, in this range can realize the ideal adjustment.
The change range of 3 outlet steam pressure for P2: P2 = 0.98MPa, the variation range of P2 is P2 + 0.4MPa; P2 > 0.98 3.82MPa, range of P2 is P2 + 0.06MPa; P2 > 3.82MPa, the variation range of P2 is P2 + 0.15MPa.
4 the regulating range of the outlet steam temperature T2 is T2 + 4.
5 device normal operation, in the lower temperature and pressure relief valve downstream one meter, while the pipe wall one meter measurement of its noise, noise level is not more than 85 db. No Information
