The basic working principle of Hydraulic Valve mainly relies on the relative movement of the valve core in the valve body to control the pressure, flow and direction of the liquid in the hydraulic system by changing the size and on-off state of the valve port. It is a key component in the hydraulic transmission system and plays a vital role in ensuring the normal operation and safety performance of the hydraulic system.
First, the gap between the Hydraulic Valve's valve core and valve body is sealed. When the Hydraulic Valve is closed, the valve core will fit tightly into the valve seat, preventing fluid from passing through. At this time, the liquid in the hydraulic system cannot flow, thus achieving the purpose of closing the hydraulic passage.
When the Hydraulic Valve needs to be opened, the control element exerts a certain force on the valve core to make it move. As the valve core moves, the channels in the valve body gradually open, allowing the pressure oil to flow from the inlet to the outlet, and the liquid in the hydraulic system can circulate. At this time, the Hydraulic Valve plays a role in regulating flow and changing flow direction.
The position of the spool determines the pressure and flow of liquid in the hydraulic system. By controlling the degree of movement of the spool, Hydraulic Valve can accurately adjust the pressure and flow of the hydraulic system to meet different working needs.
In addition, Hydraulic Valve can also automatically change the position of the valve core according to the signal from the control component to achieve automated control of the hydraulic system. This control method enables Hydraulic Valve to adapt to various complex working environments and changing work requirements.
During the working process of the Hydraulic Valve, the spring is usually used to control the initial position and reset of the valve core. When the force exerted by the control element disappears, the spring will return the valve core to its original position, closing the valve and ensuring the safety of the hydraulic system.
To sum up, the basic working principle of Hydraulic Valve is to control the pressure, flow and direction of the liquid in the hydraulic system through the relative movement of the valve core in the valve body. It relies on precision design and manufacturing, as well as its coordinated work with other hydraulic components, to achieve precise control and safety protection of the hydraulic system.
