Abstract
Description
Technical field
[0001] The present invention relates to the field of hydraulic control, and is specifically a combined hydraulic control valve.Background technique
[0002] Hydraulic drive systems or hydraulic control systems are used to control components in liquid pressure, flow, and direction. The control pressure is referred to as a pressure control valve, and the flow rate is referred to as the flow control valve, the control pass, the break, and the flow direction are referred to as the direction control valve, and the manual commutation valve is used as a direction of frequent control valve, in hydraulic pressure In the reverse control, it is an indispensable, manual replacement valve, which has a multi-directional adjustable passage, which can change the fluid flow in a timely manner, although the existing manual replacement valve can achieve the flow direction of the fluid effect.
[0003] However, prior art presence, the manual commutation valve cannot cause a problem that the lock ...
