Angle Seat Valve Steam Temperature Control Principle

Angle Seat Valve are common industrial valves that play a vital role in steam temperature control systems. The steam temperature control principle involves several steps, as follows:
1. Real-time temperature monitoring by temperature sensors: Temperature sensors are installed in the equipment or pipelines requiring temperature control. They accurately sense the current temperature conditions in real time and convert the temperature signal into an electrical signal or other transmittable form. For example, in a steam-heated reactor, a temperature sensor constantly monitors the temperature inside.
2. Signal transmission and comparison: The signal collected by the temperature sensor is transmitted to a controller. The controller, which has a set target temperature, carefully compares the actual temperature signal received with the target temperature signal and calculates the deviation between the two.
3. Controller issuance of control commands: Based on the temperature deviation, the controller uses a specific control algorithm (such as the PID control algorithm) to determine the appropriate valve operation and then issues precise control commands to the angle seat valve's actuator. When the actual temperature is lower than the target temperature, the controller issues a command to increase the angle seat valve's opening; conversely, when the actual temperature is higher than the target temperature, the controller issues a command to decrease the angle seat valve's opening. 4. Angle seat valve regulates steam flow: Upon receiving control commands, the actuator of the angle seat valve accurately operates, changing the valve opening to precisely control the steam flow rate. When the valve opening is increased, more steam can flow smoothly through the valve and into the equipment or pipeline requiring temperature control, thereby increasing the temperature. Conversely, when the valve opening is decreased, the steam flow rate decreases, and the temperature subsequently drops.
5. Achieving stable temperature control: By continuously cycling through the aforementioned steps—constantly monitoring temperature, comparing deviations, issuing commands, and adjusting valve opening—the system dynamically adjusts the steam flow rate, ultimately maintaining the temperature of the controlled object stable near the pre-set target value, achieving precise steam temperature control.
