Abstract
The invention provides a manual and electric mode switching device in an electric actuating mechanism of a valve. The manual and electric mode switching device comprises a manual actuating mechanism, a clutch which is linked with the manual actuating mechanism, a compression spring which is arranged between the manual actuating mechanism and the clutch, and a worm gear which is linked with the clutch. An eccentric groove is arranged on the worm gear. A switching device which supports the clutch is additionally arranged above the eccentric groove. The manual and electric mode switching device in the electric actuating mechanism of the valve has the beneficial effects that the manual operation of opening and closing the valve is realized under emergency situations, the accidents are prevented from occurring, the electric actuating mechanism can be automatically switched from a manual mode to an electric mode after the power is restored, on one hand, the time of manual operation is saved and the automatic switching is realized, and on the other hand, the working efficiency is improved; the structure is simple and the occupied space is small.
Description
Technical field
The present invention relates to the electric valve executing mechanism correlation technique, relate in particular to manual, electric switching device in a kind of electric valve executing mechanism.
Background technique
Growing along with the valve technology, present most of valves all can be equipped with electric actuator, dangerous occasions at some, the electric actuator device can alleviate personnel's labor intensity, reduces personnel's injury.Some Special valve requires under special circumstances emergency opening or closes, and electric valve executing mechanism can stop dangerous further diffusion factory's loss to be reduced to minimum simultaneously.Present electric actuator generally has electronic and manual two kinds of executive modes, while for electronic execution, outage or other faults occurring, can use manual executive mode to replace, yet existing manual actuator is complex structure on the one hand, fabricating cost is large, after power recovery, need manual operation manually to carry out the conversion of electronic execution on the other hand, wasted time and efficiency.
Summary of the invention
The problem to be solved in the present invention is to provide manual, electric switching device in a kind of electric valve executing mechanism, can automatically realize manually carrying out and being converted to electronic execution.
For solving the problems of the technologies described above, the technical solution used in the present invention is: manual, electric switching device in electric valve executing mechanism, comprise manual actuator, and the clutch of its interlock, be arranged on the stage clip between manual actuator and clutch, and and the worm gear of clutch linkage, it is characterized in that: described worm gear is provided with an eccentric grove, also is provided with the COMM communication of a support clutch above this eccentric grove.
Further, manually actuator comprises handwheel and the manual drives part be solid-located, and the manual drives part is meshed with clutch by dental inlay.
Further, COMM communication comprises rotatable handle and the support be solid-located, and is supported for one U-shaped, and its lower end is supported on the eccentric grove of worm gear, and upper end is supported on clutch.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, after can making power recovery, electric actuator can transfer motoring condition to from manual mode automatically, save the manually operated time on the one hand, realized automatic switchover, improved on the other hand working efficiency; And simple in structure, take up room little.

In figure: the manual actuator of 1-; The 2-clutch; The 3-stage clip; The 4-worm gear; The 5-COMM communication; The 6-output shaft; The 11-handwheel; 12-manual drives part; The 51-rotatable handle; 52-supports;
Embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention are illustrated:
As shown in Figure 1, 2, 3, the invention provides manual, electric switching device in a kind of electric valve executing mechanism, comprise manual actuator 1, and the clutch 2 of its interlock, be arranged on the stage clip 3 between manual actuator 1 and clutch 2, and and the worm gear 4 of clutch 2 interlock, worm gear 4 is provided with an eccentric grove, also is provided with the COMM communication 5 of a support clutch 2 above this eccentric grove.
Manually actuator 1 comprises handwheel 11 and the manual drives part 12 be solid-located, and manual drives part 12 is by dental inlay and clutch 2 engagements.
When electricity is arranged, the electric actuator motor drives worm screw to drive worm gear 4 and rotates, and now COMM communication 5, in idle state, does not contact with worm gear 4 with clutch 2; Clutch 2 is meshed by the dental inlay on worm gear 4, and, with worm gear 4 rotations, further drives output shaft 6 and complete spinning movement, realizes the open and close of valve;
When running into disconnection fault, power disappears, and worm gear 4 stops operating, and now shakes the rotatable handle 51 of COMM communication 5, make to support on the eccentric grove that 52 lower ends are supported on worm gear 4, upper end is supported on clutch 2, and then lifts clutch 2, and the dental inlay on the manual drives part 12 of the dental inlay on it and manual actuator 1 is meshed, then rotate handwheel 11,2 rotations of band dynamic clutch, finally drive output shaft 6 and complete spinning movement, realizes the open and close of valve;
After disconnection fault disappears, motor recovers power to start to continue to drive worm gear 4 rotations, and now, due to the effect of the eccentric grove on worm gear 4, the lower end of the support 52 on COMM communication 5 can relatively move along eccentric grove, until come off from the eccentric grove of worm gear 4.After the lower end of supporting 52 comes off, support 52 and also just no longer support clutch 2, now due to stage clip 3 in compacted state, and then can promote clutch 2 and worm gear 4 engagements, again return to electronic executing state.
This kind of structure realized the open and close of manually-operable valve in urgent by COMM communication 5, prevented the generation of accident, simultaneously after recovering electric power, can realize that manually-operable arrives the automatic switchover of electronic execution, saved the time, improved efficiency.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
