Product Introduction
Steam letdown desuperheater consists of pressure reducing system, temperature reducing system, safety protection device and automatic control device.
The new type of steam letdown desuperheater produced by our company is a device widely used to convert steam parameters in industrial boilers and thermal power plants. It can reduce the temperature and pressure of the delivered primary steam, that is, the pressure (P1) and temperature (T1) of the primary steam are reduced to the secondary steam pressure (P2) and temperature (T2) required by users.
In order to meet the user's requirements for secondary steam parameters. The thermal control cabinet can be configured to realize automatic control and operation.
Automatic control can be realized.
Product Advantage
1. Adopts the structure of temperature reducing and pressure reducing valve, so that the temperature reducing and pressure reducing of steam are carried out in the same valve, so that the length of the whole device is greatly shortened, the area of occupation is reduced, and the project investment is reduced.
2. Adopts straight stroke double valve seat temperature reducing and pressure reducing valve structure, the valve is equipped with a netting cover to enhance the atomization effect of water reducing, protect the valve seat and valve body, prolong the service life of the valve, and also reduce the noise of the device.Double - seat valve unbalance force small, wide range of regulation, smooth action, must not appear stuck phenomenon.
3. The temperature regulating system adopts the straight stroke single seat water supply regulating valve + throttling device, which can reduce the leakage of the valve and reasonably distribute the pressure difference on the water supply system. The same caliber, different flow coefficient Cv value can be selected, which greatly improves the sensitivity and accuracy of the temperature regulating system.
4. Direct stroke electric actuator is used for electric temperature reducing and pressure reducing valve and electric water supply regulating valve, which eliminates the traditional lever hinge mechanism, reduces the empty stroke link, and further improves the sensitivity and accuracy of the regulating system.
Product Structure
Steam letdown desuperheater is composed of a control system, a pressure reducer system, a water-jet temperature reducer system and a safety protection system.Its characteristics are as follows:
1. Control system: the main controller adopts high-precision multi-function digital controller, with powerful functional components, friendly man-machine interface and fast and accurate PID control loop, to achieve intelligent unmanned, flexible adjustment of parameter setting, and can be expanded according to user requirements.
2. Pressure reducing station: the decompression process of steam is realized by the throttle of the pressure reducing valve and the throttle orifice plate, and the decompression series is determined by the difference of the steam pressure after the new steam decompression.The pressure regulation of the pressure reducing valve is completed by the large actuator electric actuator. It runs smoothly and has a long life. According to the requirements of the secondary steam set value, no matter how the primary steam pressure fluctuates, the secondary steam pressure can be kept stable.
3. Temperatude-reducing device: the use of aerodynamics technology specially designed temperatude-water atomization device, using the fluid's own power to reduce the power consumption of equipment, temperatude-water is crushed into mist water droplets and steam mixed with rapid and complete evaporation, so as to achieve the effect of reducing the temperature of steam.
