In repeat no more.3rd gear 366 can be engaged with the first teeth portion 112, and the 3rd gear 366 can be departed from First Transition portion 114.
It is understood that the operation principle of the two-way blocking rotation electromechanics ball valve 300 of the present embodiment offer is：
The rotate counterclockwise of power gear 120, drives anti-blocking rotating disk 110 to rotate counterclockwise, when the first teeth portion 112 and the
Two driving cogs 134 engage, and when the first teeth portion 112 is engaged with the 3rd gear 366, two-way anti-blocking rotation mechanism 100 drives the 3rd tooth
Wheel 366 rotation.
When the second teeth portion 3641 is engaged with the first execution gear 342, first gear 362 is nibbled with the second execution gear 352
Close, second gear 364 drives the first executing agency 340 to rotate, first gear 362 drives the second executing agency 350 to rotate, and the
One executing agency 340 and the second executing agency 350 synchronous axial system, now, linkage portion 356 and groove 3231 geo-stationary, spacing
Block 346 drives boss 323 to rotate, thus carrying movable valve plug 320 gradually close encapsulation circle 330.
The structural representation of two-way blocking rotation electromechanics ball valve 300 closed valve state that Fig. 6 provides for third embodiment of the invention.
Stress at sealing ring 330I during two-way blocking rotation electromechanics ball valve 300 valve closing that Fig. 7 provides for third embodiment of the invention is illustrated
Figure.Incorporated by reference to reference to Fig. 6 and Fig. 7, when the second transition part 3642 and the first execution gear 342 depart from, second gear 364 can not
The first executing agency 340 is driven to rotate, the first executing agency 340 geo-stationary, now, first gear 362 and second executes tooth
Wheel 352 engagement, first gear 362 drives the second executing agency 350 to rotate, and now boss 323 slides on slideway 3461, linkage
Sliding on groove 3231 in portion 356, thus carrying movable valve plug 320 crush seal circle 330, applies pressure to sealing ring 330, meanwhile,
Sealing ring 330 also produces reaction force P to valve element 320, makes sealing tight.
When First Transition portion 114 and the second driving cog 134 depart from, fixed magnetic part 146 and second moves magnetic part 144
Adhesive, so that the second end tooth 1123 is engaged with the second driving cog 134, thus prevent motor to be forcibly stopped operation cause electric current
Excessive, realize anti-blocking rotating function.
So complete a circulation, when power gear 120 is when turning clockwise, operation principle is same as described above, here
Repeat no more.
To sum up, two-way blocking rotation electromechanics ball valve 300 enables two-way blocking rotation, and structure is simple, wear-resistant.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
