Features of the desuperheating and decompression device

The desuperheating and decompression device is composed of decompression system (cooling and decompression valve, orifice, etc., high pressure differential water supply regulating valve of cooling system, throttle valve, etc., safety protection device safety valve, check valve), etc. The main features are as follows:

1) The structure of small-scale temperature and pressure reduction device is adopted, and the steam is cooled and decompressed in the same valve, thereby greatly shortening the overall length of the device, reducing the occupied area, and reducing the project investment.

2) Easy to install. The structure of direct flushing double-seat cage cooling and pressure reducing valve is adopted. A throttling net cover is set inside the valve, which improves the atomization effect of desuperheating water, protects the valve seat and valve body, and prolongs the service life of the valve. It also reduces the noise of the device. The unbalanced force of the double-seat valve is small, the adjustment range is wide, the action is stable, and there will be no sticking. , Cleaning resistance; the valve seat and the valve are ground together, which overcomes the shortcomings of good sealing performance and large leakage of double-seat valves, and the applicable temperature is 510.

3) Atomization is better. Set the atomizing nozzle in the valve of the cooling and reducing valve so that the cooling water passes through the water chamber inside the valve body. The throttling between the valve seat and the valve seat keeps the flow rate of steam (that is, where the desuperheating water is injected) high, so that excellent atomization effect can be obtained even at a small flow rate of steam.

4) Noise reduction: The orifice cover set in the cooling and pressure reducing valve and the orifice behind the valve, on the one hand, play the role of decompression and atomization, and the other main function is to reduce the noise in the system. The main principle is that The small holes are silenced.

5) Wide adjustment range, straight line or corrected equal percentage characteristic curve, can be accurately controlled within the entire stroke range, ensuring that the secondary steam is within the rated output range of 10~100%, the equipment runs stably for a long time, and the leakage level is level.

6) If the amount of drainage is small, the temperature water supply adjustment system adopts a direct flushing high pressure differential regulating valve, which can reasonably distribute the pressure difference on the water supply system; the high pressure differential water supply regulating valve of the same caliber can choose different flow coefficient Cv values ​​to greatly increase the temperature Adjust the adjustment sensitivity and precision of the system.

7) Electric cooling and pressure reducing valves and electric water supply regulating valves are equipped with straight-stroke electric actuators, which eliminates the traditional lever hinge mechanism, reduces idle travel, and further improves the sensitivity and precision of the adjustment system.

The above are the characteristics of the temperature and pressure reduction device. Well, today I will introduce it here. If you have other questions, you can call us and we will definitely help you. In addition, our company is a production The temperature and pressure reduction device manufacturer has certain advantages in terms of price without middlemen. I wish you a happy life and a good mood every day!
