The basic structure of hydraulic valve and working principle
The basic structure of a hydraulic valve mainly includes a valve core, a valve body and a control device for driving the valve core to make relative movement in the valve body. The main form of the valve spool valve, cone valve and ball valve; body with the valve body in addition to the valve body hole or valve seat hole, there are external pipe inlet and outlet and drain port; drive valve The means for the core to make relative movement within the valve body may be a hand-adjusting mechanism, a spring or an electromagnet, and in some cases a hydraulic pressure drive. In the working principle, the hydraulic valve is the use of spool in the valve body relative movement to control the size of the valve opening and closing, in order to achieve pressure, flow and direction control. Hydraulic valve work, the valve size of all valves, the valve into the oil pressure between the outlet and the relationship between the flow through the valve orifice flow in accordance with the formula (q = KA · Δp m), but various valves Control parameters vary.
