The speed regulating valve is a combination valve composed of a fixed differential pressure reducing valve and a throttle valve in series. The throttle valve is used to adjust the flow rate, while the fixed differential pressure reducing valve automatically compensates for the impact of load changes, so that the pressure difference before and after the throttle valve is a fixed value, eliminating the impact of load changes on the flow.
The pressure before and after the throttle valve is introduced to the right and left ends of the valve core of the pressure reducing valve. When the load pressure increases, the hydraulic pressure acting on the left end of the pressure reducing valve core increases, the valve core moves to the right, and the pressure reducing port As the pressure increases, the pressure drop decreases, so that the differential pressure (p2-p3) of the throttle valve remains unchanged; and vice versa. In this way, the flow of the speed regulating valve is constant (unaffected by the load).
The speed regulating valve can also be designed as a structure that first throttles and then decompresses.
There is a closed cavity in the solenoid valve, and there are through holes in different positions. Each hole is connected to a different oil pipe. The middle of the cavity is a piston. On both sides are two electromagnets. Side, by controlling the movement of the valve body to open or close different exhaust holes, and the air intake holes are always open, compressed air will enter different trachea tubes, and then the piston of the cylinder is pushed by the pressure of the oil, the piston in turn Drive the piston rod, and the piston rod drives the mechanical device. In this way, the movement of the electromagnet is controlled to control the mechanical movement.
Solenoid valve classification: two-position five-way solenoid valve, three-position five-way solenoid valve, two-position three-way solenoid valve, five-port two-position solenoid valve, five-port three-position solenoid valve, three-port two-position solenoid valve, pneumatic valve, mechanical valve , Seizing valve, button valve, pilot operated solenoid valve, foot valve, manual valve, sliding vent valve, sliding vent valve, rapid exhaust valve, flow control valve, air pressure induction valve, check valve, etc.
