Hydraulic balance valve working principle
Hydraulic balance valve is a device that uses the regulation of hydraulic energy to adjust the pressure difference of hydraulic system to achieve the balance of hydraulic system. The working principle of the hydraulic balance valve is: when the pressure at the output end of the hydraulic system exceeds the set value, the hydraulic balance valve will adjust part of the flow back to the input end in accordance with the requirements of the system, so that the pressure is kept within a certain range to achieve the system
The balance of...
Hydraulic balance valve is generally composed of the valve body, valve disc, regulator, the regulator takes over the output pressure of the hydraulic system, and the valve body is provided with a valve disc, its role is to control the size of the flow by changing the opening area of the valve disc, so it can also be used to adjust the pressure difference of the hydraulic system.
When the hydraulic signal received by the regulator is greater than the set value, the regulator will send a signal to the valve flap, the valve flap will open the valve flap according to the received signal, and adjust part of the flow back to the input end, so that the pressure is kept within a certain range to achieve the balance of the system.
The advantage of the hydraulic balance valve is that it can control the flow very precisely, so as to achieve precise pressure control, and its working principle is very simple, and the reliability is very high.
