How does a joystick pilot valve work?
1. Structure and working principle of pilot valve
Pilot valve is an important component in the hydraulic system, mainly composed of valve body, spring, valve core and sealing components. There are many different designs of pilot valve structures, but the basic principles are the same.
The working principle of the pilot valve is as follows: when the solenoid valve that controls the oil flow is closed, the oil is pressed against the upstream chamber of the main valve through the spring action of the pilot valve, causing the main valve to be in a closed state. When the solenoid valve opens, the oil flows back to the tank, causing the spring to lose its force and the main valve is open.
2. The main function of the pilot valve
The main function of the pilot valve is to control the working pressure and flow of the hydraulic system. In the hydraulic system, the pilot valve can adjust the working pressure and flow in the system, thereby affecting the working status of the entire system.
It has the following three main functions:
1. Control the working pressure of the hydraulic system
The pilot valve can control the working pressure of the hydraulic system by adjusting the opening and closing status of the valve to ensure the stability of the working pressure in the system.
2. Control the working flow of the hydraulic system
The pilot valve can adjust the working flow of the hydraulic system by adjusting the opening and closing status of the valve to ensure stable working flow in the system.
3. Control the action sequence of the hydraulic system
The pilot valve can realize automatic control of the system by controlling the action sequence of each hydraulic component in the hydraulic system.
In short, the pilot valve plays an important role in the hydraulic system. It can stably control the working pressure and flow of the system, thereby ensuring the stable operation of the entire system.
