1, structural characteristics
The device consists of a vacuum system, temperature reducing system, safety protection device and automatic control device.
The vacuum system -- by temperature and pressure reduction valve and throttle orifice plate, is achieved by executing mechanism.
Temperature and reducing temperature reducing system -- by water mixing pipe, to adjust the nozzle desuperheating water flow area and with the execution of water control valve opening size to achieve the steam temperature scheduling the use of cooling water on the sprinkler head of the force and the elastic force of the spring.
Safety protection device -- is the direct use of impulse safety device (which is composed of the main safety valve and impulse safety valve) or spring safety valve to achieve two times, when the pressure exceeds the set value, the pressure more than part of the steam discharged into atmosphere, so that the two pressure is maintained within the permitted value.
2, the main performance index
1 inlet steam pressure P1 ¡Ü 10***, T1 ¡Ü 540 ℃ temperature;
2 Q: outlet flow variation range of temperature and pressure reducing device outlet flow of Q is 10% ~ 100%, in this range can achieve the desired adjustment.
Changes in the scope of 3 outlet steam pressure of P2:
P2 ¡Ü 0.98***, the variation range of P2 was P2 ¡À 0.04***;
0.98 |
