Desuperheating decompression device is used in power plants , industrial boilers and thermal power plant, etc. Both new delivered steam pressure P1 and temperature t1 will be reduced, which make the second steam pressure P2 and temperature t2 reach to be required value. Boilz desuperheating decompression device and the configuration thermal control cabinet have integrated functions of measurement and execution control, is widely used in power stations, petrochemical, light industry, metallurgy and other industrial sector and urban heating, heating system.
Desuperheating decompression device structure
Our company absorbed desuperheating decompression ‘s advanced technology and structure from foreign ,and developed such Desuperheating decompression device ,which is a new generation of products .It’s composed of 4 parts :pressure and temperature reducing valve, steam pipeline, attemperating water piping and thermal regulation device and etc.
Decompression , desuperheating and noise reduction, those three functions performe at one-stage in the valve body, which can avoid premature failure of components due to excessive temperature difference , in order to improve the service life of valve.
1、Steam pipe:
Due to the use of the pressure and temperature reducing valve, mixing pipe that sprays water to desuperheat separately in the original desuperheating decompression device is cancelled , which makes the whole device shortened about 1/2 length, compact structure, cover less area, reduce engineering investment. Pipe is installed with safety valve, pressure gauge, thermometer, etc. in order to ensure safe operation.
2、Warm water reduction system:
It’s composed of feed water regulating valve, check valve, globe valve and water supply pipeline, etc. Feed water regulator ‘s throttling element is cage sleeve or multistage throttle parts, can withstand high pressure difference, can avoid cavitation aroused when high pressure medium through the small gap, forming cavitation damage on the valve seat surface and throttling elements, and can reduce the leakage. Orifice is according to linear array, regulators with same diameter have different CV values to choose from, which can ensure precision and sensitivity.
3、The thermal control device:
It includes thermal control cabinet and electric actuator. Control mode according to the order need is divided into self-control (electronic monitoring instrument automatic control) and remote control. Automatic control cabinet includes: temperature display, pressure display, controller, alarm, operators, etc. Electric actuator used in pressure and temperature reducing valve and control valve is divided into straight travel and angular travel. Steam pressure transmitter can change steam pressure fluctuations into 4-20 m, current signal, the PI regulator conveys signals to electric execution unit driving pressure and temperature reducing valve, and then pressure is controlled. The regulation of steam temperature: thermal resistance（thermocouple）conveys 4-20 mA current signal to electric actuator through proportional integral differential unit and operator, driving feed water regulating valve to regulate the volume of water ,and then temperature is reduced.
