Abstract
The utility model discloses a manual mechanism for a hydraulic driven valve, which comprises a valve main shaft, a crank mounted on the main shaft, and a driving cylinder connecting with the crank. A manual shaft is provided correspondingly to the axial end of the valve main shaft with the same shaft center; ends corresponding to the main shaft, the manual shaft and the crank are respectively provided with driving spline teeth with the same shaft center and tooth shape, spline tooth sleeves are provided to match with the driving spline teeth; outer ring grooves of the spline tooth sleeves are provided with spline tooth sleeve moving poking forks, a screw nut poking fork driving mechanism with a handle is provided to connect with the spline tooth sleeve moving poking forks; the manual shaft is matched with a worm-worm wheel driving mechanism provided with a valve driving handle. The utility model is able to guarantee the normal operation of the valve even when the hydraulic driving system is out of control, and additionally, has the advantages of simple structure, small space occupying, low assembling cost and convenient usage.
Description
Technical field
The utility model relates to valve actuator, is specifically related to a kind of man-operated mechanism of hydraulic driving valve.
Background technique
At present, the various rotary type angular travel valves in metallurgy, the petroleum chemical industry generally adopt hydraulic driving, and it utilizes the oil hydraulic cylinder that is provided with to rotate by the crank drive main spindle that is assemblied on the valve main shaft, and drives valve plate generation angular displacement, realizes the keying of valve.The problem of its existence is when hydraulic system breaks down, and can directly cause the operation of whole valve system malfunctioning, influences the normal operation of manufacturing mechanism.For the valve hydraulic driving system fault that solves by urgent appearance makes the malfunctioning problem of valve operation, prior art adopts the double hydraulic cylinder valve driving mechanism at oil hydraulic cylinder two ends configuration hydraulic hand-pump, though this valve driving mechanism has realized operating the startup that still can keep valve when malfunctioning in main hydraulic driving system, but owing to need configuration two cover hydraulic work systems, the system architecture complexity, the equipment configuration cost height, and it is big to take up room.
Summary of the invention
The purpose of this utility model is at the problems referred to above, a kind of man-operated mechanism of hydraulic driving valve is provided, it can guarantee still when hydraulic driving system is disabled that valve normally opens and closes work, and simple in structure, take up room little, deployment cost is low, easy to use.
The technological scheme that realizes above-mentioned purpose is: a kind of man-operated mechanism of hydraulic driving valve, crank on it includes the valve main shaft and is assemblied in main shaft and the driving oil cylinder that is connected with crank, be provided with moving axis on the other hand with the corresponding concentric of valve main-axis end, in corresponding main-axis end portion, manually axle shaft end and crank end concentric isodont are respectively arranged with the drive splines tooth, match with the drive splines tooth and to be provided with the spline tooth cover, on the outer groove of spline tooth cover, be equipped with spline tooth and overlap mobile shift fork, being connected with shift fork is provided with the feed screw nut shift fork driving mechanism of configuration handle, and matching with manual axle is provided with the Worm and Worm Gear Driving mechanism of assembling valve driving handle.
The technical solution of the utility model also comprises: be provided with concentric control embedding axle at main shaft with the relative axle head of manual axle; Match with the feed screw nut driving mechanism and to be equipped with shift fork guided in translation bar.
The utility model is by disposing the manual axle by the manual worm worm-gear driven at the valve main-axis end, and in that manually axle shaft end, main-axis end portion and crank end are provided with the spline tooth of concentric isodont, utilize the spline tooth cover and the tooth that cooperate with spline tooth to overlap the conversion that mobile shifting fork mechanism is finished hydraulic driving and manual drives, thereby realized the manually-operable of valve when hydraulic driving is malfunctioning, and had that system architecture is simple, the characteristics little, that deployment cost is low, easy to use take up room.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is described.
As accompanying drawing, the man-operated mechanism of this hydraulic driving valve includes valve main shaft 1, is equipped with crank 2 on main shaft 1 movingly, with the crank hinge driving oil cylinder 3 that has been linked and packed.Be provided with manual axle 6 with the corresponding concentric of valve main-axis end, in corresponding main-axis end portion, manually axle shaft end and crank end concentric isodont are respectively arranged with drive splines tooth 4, match with the drive splines tooth and to be provided with spline tooth cover 5, the spline tooth cover is provided with outer groove and is equipped with spline tooth and overlaps mobile shift fork 12, is connected with shift fork to be provided with the feed screw nut shift fork driving mechanism 11 of assembling handle 10.Match with manual axle 6 and to be provided with the Worm and Worm Gear Driving mechanism 8 of assembling valve driving handle 7.
The utility model can be provided with concentric control embedding axle 9 with the relative axle head of manual axle 6 at valve main shaft 1, so that manually axle has better concentricity with the valve main shaft.During concrete enforcement, embedding axle 9 can be arranged on the axle head of main shaft 1 as shown in drawings, also can be arranged on the axle head of manual axle 6.
For guaranteeing that shift fork 12 overlaps 5 o'clock stably translationals stirring spline tooth, the utility model can be provided with shift fork guided in translation bar 13 in the bottom of shift fork, when specifically implementing, offers the guide rod mounting hole in the bottom of shift fork, guide rod 13 drives leading screw with shift fork and be arranged in parallel, is threaded onto in the guide rod mounting hole.
When spline tooth cover 5 of the present utility model was in position shown in the accompanying drawing, the spline tooth cover fused crank 2 and valve main shaft 1, and the keying of valve is finished by hydraulic driving system; When hydraulic driving system breaks down akinesia, by handling feed screw nut shift fork driving mechanism, make spline tooth cover 5 move to manual axle 6 on the spline tooth engagement simultaneously with crank 2 on the position that breaks away from of spline tooth, handle with sleeve 7 can be realized the manually-operable of valve opening and closing.
