Attemperation valve is a switch valve mainly used for high-temperature gas, and is used at the outlet of sulfuric acid plant boilers. It has the characteristics of compact structure, small footprint, strict airtightness, and high reliability.
The structure of the attemperation valve mainly consists of components such as the driving device synchronous runner, bracket, cylinder, guide rod, valve body, and valve disc. The operating principle is that when the driving device is powered on, it rotates to drive the guide rod, which is connected through the guide rod.
The shaft transmits motion to the valve disc, causing it to move upward and achieve the purpose of opening. On the contrary, if the driving device is reversed, the valve disc will fall and close.
Performance Range:
Diameter: | DN15~DN300mm |
Flow rate: | 0.5～50m3/h |
Head: | 200～1000m |
Pressure: | 1.6～10 MPa |
Temperature: | Up to 600℃ |
Applications:
The attemperation valve is used between the outlet of the sulfuric acid plant boiler and the inlet of the converter. Due to the high temperature of the flue gas at the boiler outlet, the attemperation valve controls the temperature of the flue gas entering the converter by adjusting the opening and closing angle of the valve disc.
