Structural characteristics

The split type temperature and pressure reducing device is composed of pressure reducing system, temperature reducing system, safety protection device and automatic control device. Pressure reduction system - by the pressure reduction valve and orifice plate, through the automatic control system sampling, calculation, output control actuator to adjust the valve opening to achieve steam pressure regulation. Temperature reduction system - adopt the way of spraying water in the mixing pipe to reduce temperature, adjust the flow area of the nozzle cooling water by using the action of the cooling water on the sprinkler head and the elastic force of the spring, and adjust the steam temperature by the opening of the feed water regulating valve controlled by the actuator. Safety protection device - is a direct use of impulse safety device (mainly composed of the main safety valve and impulse safety valve) or spring safety valve to achieve, when the secondary pressure exceeds the prescribed value, the pressure over part of the steam into the atmosphere, so that the secondary pressure to maintain within the allowable value. Automatic control device - with our company's RKG - _steam pressure and temperature control device, new steam through the device, so that the secondary steam parameters to maintain the required stability.

performance index

1. the inlet steam pressure is P1 or less than 10MPa, and the temperature is T1 or less than 540 C.

2. Outlet flow Q: The variation range of outlet flow Q of the vacuum and temperature reduction unit is 10%~100%, within which ideal regulation can be realized.

3. The variation range of outlet steam pressure P2 is: P2 < 0.98 MPa, P2 < 0.4 MPa; 0.98 < P2 < 3.82 MPa, P2 < 0.06 MPa; P2 > 3.82 MPa, P2 < 0.15 MPa.

4. the regulating range of the outlet steam temperature T2 is T2 + 4 C.

5. When the device is in normal operation, the noise is measured at one meter downstream of the reducing temperature and pressure valve and one meter away from the pipe wall. The noise level is no more than 85 dB.

Scope of supply

The supply range of split type temperature and pressure reducing device is:

1. decompression system: pressure reducing valve, electric (pneumatic) actuator, throttling orifice, etc.

2. temperature reduction system: water supply control valve, electric (pneumatic) actuator, throttle valve and so on.

3. safety system: safety valve, check valve, etc.

4. piping system: steam pipe, transition pipe, temperature reducing water pipe, mixed pipeline, etc.
