Electric regulating valve is a kind of flow regulation equipment, through electric drive and precise control of the gap between the valve core and the seat, to achieve the adjustment of the medium flow. In industrial production, the correct selection and application of electric control valves is essential to ensure the safe, reliable and efficient operation of fluid delivery systems. This article will introduce the selection and application skills of electric regulating valve from a professional perspective.
First, selection skills
1. Determine the valve type
According to the working conditions of the fluid conveying system and the characteristics of the medium, select the appropriate valve type, such as single-seat regulating valve, two-seat regulating valve, sleeve regulating valve, etc.
2. Select the actuator type
According to the requirements of adjustment accuracy, response speed and installation space, select the appropriate actuator type, such as straight stroke, angular stroke and multi-turn actuator.
3. Determine valve size and material
According to the flow rate, pressure, temperature and other parameters of the fluid, select the appropriate valve size and material to ensure the strength and corrosion resistance of the valve.
4. Choose the appropriate control method
According to the degree of automation and operational requirements of the fluid delivery system, select the appropriate control mode, such as manual control, automatic control and remote control.
Two, the application of skills
1. Install and connect cables
When installing the electric control valve, it should be ensured that the valve is firmly connected to the pipeline, and the power cord and control line are correctly connected to avoid wiring errors.
2. Debugging and calibration
Before the electric control valve is put into use, it should be adjusted and calibrated to ensure that the valve is opened and closed normally and the flow regulation accuracy meets the requirements.
3. Proper use and maintenance
During the use of the electric control valve, the operating procedures should be followed to avoid excessive operation and overload. At the same time, regular maintenance and maintenance to extend the service life of the valve.
4. Troubleshooting and maintenance
When the electric control valve fails, it should be investigated according to the fault phenomenon, find out the cause of the fault, and take the corresponding maintenance measures. Such as actuator failure, spool and valve seat wear and other problems, should be repaired or replaced in time.
Iii. Summary
The selection and application skills of electric regulating valves include determining the valve type, selecting the actuator type, determining the valve size and material, and selecting the appropriate control mode. In practical applications, it is also necessary to pay attention to installation and wiring, debugging and calibration, correct use and maintenance, as well as troubleshooting and maintenance, to ensure the safe, reliable and efficient operation of the electric regulator. Understanding the selection and application skills of electric regulating valve is helpful to improve the management level and technical level of fluid conveying system.
