Detailed introduction:
I. overview of self operated flow balancing valve:
Self operated flow balancing valve is suitable for load liquid pipeline system, and it is an ideal new energy saving valve. The valve is calibrated with digital display, which can be directly transferred to any position and can be locked. The valve is mainly used in industrial and civil buildings heating pipeline system. At present, in some network system exists in the hydraulic imbalance, balance valves offer a solution to this always means, and it can adjust the pressure and flow accurately, to improve the liquid pipeline system in flow condition of fluid balance and network, reach the purpose of saving energy. In the transformation of dual network engineering, application of this valve can save energy, get good effect. The company is the production of equal percentage characteristics of the valve. When the opening rate is equal to the change rate, the change rate of the flow is equal, which is characterized by the application when the flow rate is large, until the percentage valve is suitable for this requirement. According to this characteristic, you can freely set a flow (quick open valve and linear valve does not have this function), and when you need to change, you can also know the amount of change, to achieve the desired state. The main parts are as follows:
