The balance valve is a special function valve. The valve itself has no special place, only the difference between the use function and the field.In some industries, there are large pressure differences or flow differences in each part of the pipeline or container due to the medium (various types of flowable substances).Set a valve to regulate the relative balance of the pressure on both sides, or to achieve the balance of the flow through the diversion method. The valve is called a balance valve.
The role of the balance valve
The balance valve is a special function valve. It has a quantitative measurement function and adjustment function. During the system debugging, the debuggling personnel can adjust the balance valve through dialogue with the special intelligent instrument human machine to realize the hydraulic balance of the system.It has good traffic regulation characteristics, and the relative flow and relative opening are linear.There are precise valve opening instructions, and the minimum reading is 1 ℅ with full openness of the valve.There is a reliable openness lock memory device, and the valve can be restored to the original locking position after changing the openness of the valve.There is a cut -off function. If you install the balance valve, you dont have to install the deeper valve.
Working principle of balance valve
The working principle of the dynamic balance valve The dynamic balance valve is divided into dynamic flow balance valves, and the self -type self -pressure difference control valve.The dynamic flow balance valve is also known as: self -efficient flow control valve, self -efficient balance valve, fixed flow valve, automatic balance valve, etc. It is based on the change of the system (pressure difference) and automatically changes the resistance coefficient.Within the range, the flow of traffic can be effectively controlled to maintain a constant value, that is, when the pressure difference between the front and rear valves increases, the automatic small movement through the valve can maintain the flow.The automatic opening, the traffic is still constant, but when the pressure difference is less than or greater than the normal working range of the valve, it cannot provide an additional pressure head after all. At this timeLow or high traffic cannot be controlled.
