Continue the operation upper part handwheel, initiatively partial gear 15 meshes with driven partial gear II 13, and the locking device 6 that links to each other with connecting rod II (locking) 11 is unclamped in drivening rod II (locking) 11 actions.This moment, initiatively the boss of partial gear location-plate 19 did not cooperate with the groove of driven partial gear II 13 location-plates 17, guaranteed that initiatively partial gear 15 is smooth and easy with the engagement of driven partial gear II 13.After initiatively partial gear 15 was thrown off with driven partial gear II 13 engagements, initiatively partial gear location-plate 19 boss entered driven partial gear II 13 location-plates 17 grooves, and driven partial gear II 13 positions are fixed.
Continue the operation upper part handwheel, initiatively partial gear 15 and driven partial gear III 14 engagements are with carry-over bar 10 actions, by the connectors such as bevel gear of middle part transmission case, open hermatic door.This moment, initiatively the boss of partial gear location-plate 19 did not cooperate with the groove of driven partial gear III 14 location-plates 18, guaranteed that initiatively partial gear 15 is smooth and easy with the engagement of driven partial gear III 14.After initiatively partial gear 15 was thrown off with driven partial gear III 14 engagements, initiatively partial gear location-plate 19 boss entered driven partial gear III 14 location-plates 18 grooves, and driven partial gear III position is fixed.At this moment, the operation of access lock proximal seal door is finished.
During operation far-end door, the bottom handwheel is operated, by the chain of power transmission shaft 7 and middle part transmission case, drive the transmission case operation of far-end, movement locus is identical with the top handwheel, and finishes the operation to the far-end door.
At closing time, operating personnel operate transmission case top handwheel, direction is opposite when opening the door, at first be that initiatively partial gear location-plate 19 boss skid off from driven partial gear III 14 location-plates 18 grooves, initiatively partial gear 15 meshes with driven partial gear III 14, drive tooth bar 10 actions that are connected with driven partial gear III 14, by the connectors such as bevel gear of middle part transmission case, close hermatic door.
Continue the operation upper part handwheel, initiatively partial gear location-plate 19 boss enter driven partial gear III location-plate 18 grooves, and from driven partial gear II 13 location-plates 17 grooves, skid off, initiatively partial gear 15 meshes with driven partial gear II 13, drive connecting rod II (locking) action that is connected with driven partial gear II 13, make locking device 6 actions, the press seal circle.
Continue the operation upper part handwheel, initiatively partial gear location-plate 19 boss enter driven partial gear II location-plate 17 grooves, and from driven partial gear I 12 location-plates 16 grooves, skid off, initiatively partial gear 15 meshes with driven partial gear I 12, drive the connecting rod I 2(equalizing valve that is connected with driven partial gear I 12) action, the closing presure equalizing valve.
Meanwhile, along with travelling gear train 4 is rotated, pole 30 is pushed down interlocking and is stuck up piece 27, drivening rod I 2(equalizing valve) up motion, when pole 30 arrived assigned address, interlocking ratchet 28 broke away from interlocking gear 29, restPose, two handwheels all can operate on each transmission case.
Under the particular case, if need to remove interlocking, can pack into and stick up the pole that piece 27 is complementary with interlocking, can not rotate so that interlocking sticks up piece 27, can remove interlocking, satisfy instructions for use.
In whole transmission system, by operation transmission case bottom handwheel, can finish the aforesaid operations to access lock far-end door, motion process is consistent.
