The invention discloses a power failure maintaining device of a hydraulic direction-changing valve. The power failure maintaining device of the hydraulic direction-changing valve comprises a first hinge support, a second hinge support, a position changing lever, a position changing electromagnetic valve, a returning lever and a returning electromagnetic valve, wherein one end of the position changing lever is articulated in the first hinge support; the end of a valve element of the hydraulic direction-changing valve abuts against the side of the position changing lever; a lock pin is convexly arranged on the position changing lever; the end of a valve element of the position changing electromagnetic valve is articulated with the other end of the position changing lever; the position changing electromagnetic valve is used for driving the position changing lever to swing; one end of the returning lever is articulated in the second hinge support; a lock card is convexly arranged at the other end of the returning lever; the lock pin on the position changing lever abuts against the bottom end of a slope of the lock card of the returning lever in an initial state; the end of a valve element of the returning electromagnetic valve is articulated with the middle part of the returning lever; the returning electromagnetic valve is used for driving the returning lever to swing. According to the power failure maintaining device of the hydraulic direction-changing valve, the lock pin of the position changing lever cooperates with the lock card of the returning lever to implement the power failure maintaining function of the hydraulic direction-changing valve; the power failure maintaining device is simple in structure and easy to implement, and achieves power economization and energy economization.
Description
technical field [0001] The invention relates to the field of hydraulic reversing valves, in particular to a power-off holding device for hydraulic reversing valves. Background technique [0002] Some hydraulic reversing valves in the hydraulic system need to be kept in the transposition working state for a long time. At present, there are four types of hydraulic reversing valves that meet this requirement: manual reversing valve with steel ball positioning, stroke reversing valve, electromagnetic reversing valve valve, electro-hydraulic reversing valve. Among them, the manual reversing valve with steel ball positioning requires manual operation, manual reversing, high labor costs, and slow response time, which is inconvenient for industrial automatic control occasions. The stroke reversing valve is driven by the iron stopper or cam on the mechanical moving parts, and it is applied to the equipment with the stroke reversing mechanism. It is a passive reversing valve and cann...
