(1) hydraulic lock in series in the oil return circuit
The reverse oil circuit of the hydraulic control check valve can only be connected after the control oil circuit inputs a certain pressure oil. It is a kind of switch element that can control the oil circuit on and off. It is also called hydraulic lock. The hydraulic lock is connected in reverse series in the return oil circuit of the hydraulic cylinder (hydraulic motor), and the control oil circuit is connected with the inlet oil circuit of the hydraulic cylinder (hydraulic motor), so that the return oil circuit can be cut off under the braking state because the control oil circuit has no pressure oil effect, and the hydraulic cylinder (hydraulic motor) has the due locking effect.
The locking effect of the hydraulic lock depends on the shape of the valve core and the structure type of the valve.
