he 400X flow control valve is a multifunctional valve that uses high-precision pilot control to control flow, mainly used in water supply, air conditioning, fire pipeline systems, etc. Its working principle is as follows: When the valve supplies water from the inlet end, the water flows through the needle valve into the main valve control room, and flows out of the main valve control room to the outlet through the pilot valve and ball valve. At this time, the main valve is in a fully open or floating state. By adjusting the flow control valve, a certain opening degree can be set for the main valve. Adjusting the needle valve opening and the pressure of the pilot valve spring can keep the main valve opening at the set opening, and automatically adjust the pilot valve when the pressure changes to maintain the same flow rate.
The working principle of the 400X flow control valve includes the following steps: 1. Open the needle valve and ball valve, loosen the anti loosening nut of the pilot valve, turn the regulating screw of the pilot valve clockwise, the pilot valve core opens, and the medium flows through the pilot valve to the outlet. 2. The pressure in the upper chamber of the main valve diaphragm decreases. Under the action of medium pressure, the main valve core opens, and the medium flows through the main valve core to the outlet. The flow rate behind the valve begins to increase. When the flow rate behind the valve rises to the set value, the pressure under the pilot valve diaphragm and the set spring remain balanced, and both the pilot valve and the main valve maintain a certain degree of opening, and the flow control valve works normally.
The 400X flow control valve has the following characteristics: 1. High precision control: able to maintain the predetermined flow rate unchanged, limit excessive flow to a predetermined value, and appropriately reduce upstream high pressure. 2. Safe and reliable: Even if the pressure changes upstream of the main valve, it will not affect the flow downstream of the main valve. 3. Simple debugging: convenient debugging during use, and long service life of 34. In summary, the 400X flow control valve achieves precise regulation of flow and pressure control through high-precision pilot control, and is widely used in various pipeline systems that require flow control.
