Embodiment
With reference to accompanying drawing, one can realize the auto reversive control valve of oil hydraulic cylinder, includes lower filler opening 12, combined seal ring 13, piston rod 16 and valve body 1, be provided with in valve body 1 by return opening 10, upper filler opening 11, first pull-out piece spring screw 2, first red copper pad 3, steel ball 5 on first, first push rod 6, seal ring 7, collision block 8, gland nut 9, the pilot valve that first time steel ball 14 and controlling rod 15 form, on described first pull-out piece spring screw 2 and first, steel ball 5 is located in the first upper cavity 24, first time steel ball 14 is located in the first lower chamber 25, it is characterized in that: correspondingly with pilot valve in same valve body 1, be provided with pilot operated directional control valve, this pilot operated directional control valve is by plunger 17, steel ball 18 on second, second time steel ball 19, second pull-out piece spring screw 20, second red copper pad 21, circlip for hole 22, second push rod 23 and the plug 4 being located at pilot operated directional control valve lower end are formed, on second pull-out piece spring screw 20 and second, steel ball 18 is located in the second upper cavity 26, second time steel ball 19 is located in the second lower chamber 27, the first described upper cavity 24 and the second upper cavity 26 utilize and are communicated with runner 28 and link together and be connected together with upper filler opening 11, and the first described lower chamber 25 and the second lower chamber 27 utilize lower communicating tube runner 29 to link together and be connected together with return opening 10.
Working procedure of the present utility model is as follows:
After access hydraulic oil, upper filler opening 11 and the oil-feed simultaneously of lower filler opening 12, under pressure, the first steel ball 5 seals the first push rod 6 upper end hydraulic fluid port, lower end fluid enters piston loculus, promote piston rod 16 moves, controlling rod 15 in piston rod 16 promotes the first push rod 6 simultaneously and moves up, after backing down steel ball 5 on first, hydraulic oil enters the lower end of pilot operated directional control valve by the lacuna of the first push rod 6 (pilot valve first time steel ball 14 withstands the nose end of the first push rod 6, close oil circuit), promote plunger 17, second time steel ball 19 of lower end in pilot operated directional control valve, second push rod 23, on second, steel ball 18 moves, on second steel ball 18 open after (second time steel ball 19 of pilot operated directional control valve lower end withstands the nose end of the second push rod 23, close oil circuit), the lacuna of hydraulic oil second push rod 23 in pilot operated directional control valve enters the large chamber of piston, and to promote piston rod 16 descending, after piston rod 16 goes downwards to certain position, collision block 8 encounters controlling rod 15 end, drive controlling rod 15 descending, open pilot valve lower end, connect return opening 10, hydraulic oil oil sump tank, pilot operated directional control valve also loses fuel feeding simultaneously, and under the pressure effect of the upper filler opening 11 of upper end, two valve upper end hydraulic fluid ports are all closed.Under the pressure effect of lower filler opening 12, piston rod 16 is up, repeats last process, so constantly back and forth realizes the automatic reverse of oil hydraulic cylinder.
