Abstract
The utility model provides a fast and low-speed control valve assembly which is formed by an oil-way block, a stacked pressure reducing valve, a transition block, a three-position four-way electromagnetic directional valve, a stacked unidirectional throttle valve and a two-position three-way electromagnetic directional valve. The fast and low-speed control valve assembly is used to realize the fast and low-speed control of an oil cylinder. When an electromagnet 1DT of the three-position four-way electromagnetic directional valve is energized and 2DT loses electricity, a piston of the oil cylinder draws back. When the electromagnet 1DT of the three-position four-way electromagnetic directional valve loses the electricity, 2DT is energized and two-position three-way electromagnetic directional valve 3DT is not energized, the piston of the oil cylinder moves forward fast. When the electromagnet 1DT of the three-position four-way electromagnetic directional valve loses the electricity, 2DT is energized and two-position three-way electromagnetic directional valve 3DT loses the electricity, the piston of the oil cylinder moves forward slowly. A structure of the valve assembly is simple. Installation is convenient. Internal oil-way design of the transition block is compact and processing is simple, which is conducive to improve overall quality and reduce cost.
