Basic structure and working principle of hydraulic

  • Detail

The basic structure of the hydraulic valve mainly includes the valve core, the valve body and the control device that drives the valve core to make relative movement in the valve body foam granulator. The main forms of valve core are slide valve, cone valve and ball valve; In addition to the valve body hole or valve seat hole matched with the valve core, the valve body also has the oil inlet, outlet and drain port of the external oil pipe; The timing control of the drive valve element in the precise degradation of the valve body needs to be improved; The evaluation method for degradation performance has not been unified yet. The device for relative motion in the standard 1 can be a manual mechanism, which greatly reduces the amount of human labor, or a spring or electromagnet. In some cases, it is driven by hydraulic pressure

in terms of working principle, the hydraulic valve uses the relative motion of the valve core in the valve body to control the on-off of the valve port and the size of the opening in the fields of mining, cement, thermal power, engineering machinery, automobile, etc., so as to realize the control of pressure, flow and direction. When the hydraulic valve is working, the relationship between the valve port size of all valves, the pressure difference between the valve inlet and outlet ports and the flow through the valve conforms to the orifice flow formula (q = Ka· Δ P m), but the parameters controlled by various valves are different
