Hydraulic control valves are classified according to principle Hydraulic control valves are components used to control the direction, pressure and flow of hydraulic fluid in hydraulic systems. They regulate and control the starting, stopping, moving direction, speed, movement sequence and overcoming load of actuators , So that all types of hydraulic machinery can be required to coordinate the work. Structurally, all hydraulic valves are made up of the valve body, the valve core and the components that actuate the valve spool. In principle, the opening size of all hydraulic valves, the pressure difference between the inlet and outlet, and the flow rate through the valve The relationship is consistent with the orifice flow formula, only a variety of valve control parameters vary. Hydraulic control valve according to the principle of classification ①directional control valve: used to control the direction of hydraulic fluid flow or liquid flow and off, divided into one-way valve and the two types of valve. ② pressure control valve: control of oil pressure Level or the use of pressure changes to achieve some kind of action, such as relief valve, pressure relief valve, sequence valve, pressure relay, etc. ③ flow control valve: used to regulate the output flow to control the actuator speed, such as throttle Speed ​​valve and so on.
