Continuous blowdown valve for imported boiler
The continuous blowdown valve of YLOK imported boiler from the United States is a multi-stage pressure reducing valve for anti-cavitation. The specially designed valve trim makes the fluid pressure drop step by step, controls the flow rate, and prevents cavitation damage; the throttle part is separated from the sealing surface to effectively protect the sealing surface. The surface of the valve trim is hardened to achieve a hardness of about HRC70, which is resistant to erosion and has a long life; there are large gaps on the surface of the valve core, and the fluid contains particles, and the valve core will not jam. This valve is mainly used in thermal power plants to continuously remove part of the salt dissolved in boiler water, and is one of the key valves for power plants to control high pressure differential saturated water.
Parameter description of continuous blowdown control valve for imported boiler:

Structural features of continuous blowdown valve for imported boilers:
1. The fluid pressure is reduced step by step, and the direction of the fluid changes continuously, increasing the flow resistance. Control the flow rate to prevent cavitation damage.
2. Multi-stage throttling, and the fluid passage is gradually expanded to suit the characteristic that saturated liquid becomes steam volume expansion as pressure decreases, reducing fluid erosion and erosion on the valve core.
3. The throttle surface is separated from the sealing surface to effectively protect the sealing surface. The surface of the valve core and valve core sleeve is hardened, and the hardness reaches about HRC70, close tightly, and long life.
4. Good flow adjustment characteristics, large adjustment range nbsp;
5. There is a large gap on the surface of the valve core, the fluid contains 2-3mm, welding slag and other solid particles, the valve core will not be stuck, and the action will be flexible.
