The pressure fluctuation of the network can be absorbed and the flow of the controlled load can be maintained constant. The pressure fluctuation of the network can be absorbed and the internal disturbance (resistance change in the controlled loop) can be overcome to maintain the constant pressure difference applied to the controlled loop. During system debugging, the commissioning personnel can realize the hydraulic balance of the system by talking with the special intelligent instrument and adjusting the balance valve.
The valve opening indication with * is 1% of the valve full opening. Reliable opening locking memory device is available, and the valve opening can be restored to the original locking position after the valve opening changes. With stop function, the balance valve is installed without the need for stop valve.
The balance valve belongs to the category of regulating valve. Its working principle is to change the clearance between valve core and valve seat (i.e. opening), change the flow resistance of fluid flowing through the valve, and achieve the purpose of regulating flow.
Extended information
Performance characteristics
1. Ideal regulation performance;
2. * cutoff function;
3. * display of opening status to 1 / 10 turn;
4. The theoretical flow characteristic curve is equal percentage characteristic curve;
5. National * type opening and closing locking device;
6. Each complete circle has a flow coefficient. In the debugging, as long as the pressure difference between the two ends of the valve is measured, the flow rate through the valve can be calculated conveniently;
7. The sealing performance of polytetrafluoroethylene and silica gel is reliable;
