What should you pay attention to when using a large flow control valve?
The speed regulating valve is an accessory on the fluid pipeline. On the pipeline, it can adjust the speed and flow of the fluid so that the speed and flow of the fluid on the pipeline meet the needs of actual application. What should we pay attention to when using a large flow speed regulating valve?
1. When adjusting the flow rate, you need to loosen the fastening screw on the handle first. Generally speaking, if you rotate it clockwise, the flow rate will increase, and if you rotate it counterclockwise, the flow rate will decrease. After adjusting to the appropriate flow rate, you need to tighten the fastening screw.
2. Pay attention to the speed adjustment range and adjust the flow rate within the adjustment range. Once the allowable flow value range is exceeded, it will cause pressure loss and temperature rise failure. Pay attention to the stable flow value, and the speed adjustment range cannot be less than the specified stable flow.
3. If a differential pressure reducing valve is used as a speed regulating valve for a pressure compensator, in order to obtain a satisfactory flow rate, the pressure at the valve inlet cannot be lower than 1 bar. If the pressure is too low, the flow stability will deteriorate, or even flow interruption may occur.
4. In order to obtain satisfactory flow regulation, the pressure difference between the throttle and the inlet and outlet should be reasonable, otherwise the flow will be unstable, thus affecting the normal operation of the pipeline.
5. When the differential relief valve is used as a speed regulating valve for pressure compensator, some oil will enter the oil tank through the relief valve. Therefore, there are special regulations for the pump flow and valve flow. Usually, the pump flow is required to be greater than the valve flow by a certain value.
In a word, the speed control valve serves the fluid engineering. Once the fluid engineering fails, the progress of the entire project will be delayed. Therefore, the above five points should be paid attention to when using a large flow speed control valve .
