Abstract
The utility model relates to a manual/electric switching mechanism of an electric device of a miniature partial rotary valve, which comprises a high-speed worm wheel, a clutch sleeve, a spring, a manual shaft, a through cover, a switching hand grip, a switching hand grip pinion and a manual arm, etc. A coaxial ladder hole is arranged in the through cover, the clutch sleeve and the manual shaft are installed in the hole, a spring and a rolling ball are installed between the clutch sleeve and the manual shaft, and the gear rack joggled with the switching hand grip pinion is arranged on the outer column of the clutch sleeve. The manual/electric switching mechanism of the electric device of the miniature partial rotary valve has the advantages that when the power supply is failed or the debugging operation is performed, the manual/electric switching mechanism can meet the demand of the manual operation of the electric device of the valve, and is also provided with high reliability and security, and can ensure that the operating requirement of the electric device of the miniature partial rotary valve can be satisfied, and the switching is reliable, the reposition is flexible, and the use is safe and convenient.
Description
Technical field
The utility model belongs to electric valve switching technique field, particularly relates to a kind of small-sized part turning valve Electric actuator hand/electronic switching mechanism that can satisfy the electric device for valve manual operation and have high reliability when having a power failure or debug.
Background technique
Electric device for valve hand in the known technology/electronic switching mechanism mainly contains three kinds of forms, the full type hand structure of the first, and promptly manual mode all needs manpower to finish to the conversion of electric model or electric model dynamic model formula in one's hands; Its two, be the semi-automatic electric preferred form, i.e. the conversion of electric model dynamic model formula in one's hands needs manpower, and manual mode being converted to automatically to electric model; It three is full-automatic patterns, i.e. conversion does not between the two need artificially to switch.Long term production proves that above-mentioned full type hand reliability of structure is lower, how not to adopt at present.Its complex structure of switching mechanism of full-automatic pattern and have narrow limitation is subjected to the restriction of operating mode easily during application.The frequent form of using in related domain is the preferential formula switching mechanism of semi-automatic electric at present, the preferential formula switching mechanism of semi-automatic electric is divided into output shaft (being commonly referred to lower velocity shaft) or two kinds of topology layouts of worm shaft (being commonly referred to high speed shaft) again, when lower velocity shaft switches, its switching power is big and manually-operable power is also bigger, high speed shaft seems then when switching that mechanism is complicated, deal with improperly simultaneously and have potential safety hazard, especially not too suitable to the hand/electronic switching mechanism of present small-sized part revolution Electric actuator.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of can satisfy small-sized part turning valve Electric actuator usage requirement and switch reliable, small-sized part turning valve Electric actuator hand/electronic switching mechanism flexible, safe and convenient to use resets.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: small-sized part turning valve Electric actuator hand/electronic switching mechanism, comprise the high speed worm gear, clutch sleeve, spring, manual axle, logical lid, switch handle, switch handle small gear and manual arm, it is characterized in that: have coaxial shoulder hole at Tong Gainei, clutch sleeve and manual axle are installed in the coaxial shoulder hole, between clutch sleeve and manual axle, spring and ball are housed, manually be connected with manual arm on the axle, the clutch sleeve outer cylinder is provided with and the tooth bar that switches the handle pinion.
The utility model can also adopt following technological scheme:
Described logical lid one side has the hole vertical with coaxial shoulder hole, is equipped with in this hole to switch the handle small gear.
Advantage and the good effect that the utlity model has are: because the utility model has adopted at Tong Gainei clutch and manual handle and spring is housed and ball and being equipped with and the ring-type rack structure that switches the handle pinion between the two on the clutch outer cylinder are installed, when the manual needs of operator according to valve, when the direction of arrow shown in pressing promotes to switch handle, drive clutch sleeve and move and the two tooth is imbedded into engagement by switching rotatablely moving of handle small gear, and then the switching power that clutch is produced is less to manual axle position.In addition, because an end of spring armrest moving axis acts on the ball, therefore, can not drive manual arm during the electronic rotation of high speed worm gear and rotate, so guaranteed the Security of operating.The utility model also have overall structure simple, switch reliable and the advantage flexibly that resets.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1, high speed worm gear; 2, clutch sleeve; 3, spring; 4, manual axle; 5, ball; 6, Tong Gai; 7, switch handle small gear, 8, manual arm; 9, key; 10, switch handle.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, small-sized part turning valve Electric actuator hand/electronic switching mechanism, comprise high speed worm gear 1, clutch sleeve 2, spring 3, manually axle 4, ball 5, logically cover 6, switch handle 10, switching handle small gear 7 and manual arm 8.Have coaxial shoulder hole in 6 logical the lid, clutch sleeve 2 and manual axle 4 are installed in the coaxial shoulder hole, between clutch sleeve and manual axle, spring 3 and ball 5 are housed, manually on the axle 4 key 9 and manual arm 8 are housed, described logical lid one side has the hole vertical with coaxial shoulder hole, be equipped with in this hole and switch handle small gear 7, the clutch sleeve outer cylinder is provided with and the tooth bar that switches 7 engagements of handle small gear, switches 7 connections of handle small gear and switches handle 10.The other end tooth embedding of clutch sleeve 2 is meshed with the tooth embedding on the high speed worm gear 1, can guarantee the engagement of this switching mechanism electric model like this and finish spreading out of of motion by key 9.
Working principle of the present utility model is: the operator is according to the manual needs of valve, promote to switch handle 10 in the direction of arrows, clutch moves to manual axle 4 positions under the drive that switching handle small gear 7 rotatablely moves, and the two tooth is imbedded into engagement, rotation manual arm 8 gets final product, and by key 9 manually operated motion is spread out of.When finishing manually-operable, unclamp and switch handle 10, clutch sleeve automatically resets to high speed worm gear tooth embedding engagement and finishes the conversion of manual operation mode to the electric operating pattern under the effect of spring 3, because an end of spring armrest moving axis 4 acts on the ball 5, so can not drive manual arm 8 during the electronic rotation of high speed worm gear 1 rotates, and considered that in design clutch sleeve and the embedding of high speed worm gear tooth disengagement earlier enters and the manually engagement of axle tooth embedding again, thereby can guarantee handling safety.
