The spool of 2/2-way ball valve 2,3,4 is by the follower 8a of keyway on the spheroid and partial gear intermittent drive mechanism, 8b, and 8c cooperates rotation, the control of throttle valve 5 manual tune; , be connected at anterior turning circular groove that ball valve sealing stops up and with hole path in sealing is stopped up through opening file annular groove, drilling hole in valve body 1 inside, these grooves and hole have constituted the passage of control loop requirement.Be connected to two fluid leading pipe a, b to remedy the inner deficiency that is connected with the ball valve sealing blocking channel of valve body in the valve body outside weld, also can take other connecting passage forms.
The incomplete driving gear 6 of indexing mechanism is that real the number of teeth is arranged is the 42 teeth imagination tooth partial gear of 19 teeth, and follower 8a, 8b, 8c are 42 tooth full-depth tooths wheels, velocity ratio 1:1; Three follower 8a, 8b, 8c whenever mesh with incomplete driving gear 6 at a distance from 90 ° one, become " parallel connection " form to connect; Drive sprocket axle 7 front ends are hexangle type handle connecting head, and drive sprocket axle 7 rear ends connect the driven wheel disc 16 of free wheel device; The front end position of intermittent drive mechanism drive sprocket axle 7 is equipped with the permanent magnet of a band magnetic shield; On valve body with the per 90 ° of positions of the circumference at the same horizontal plane of permanent magnet position, the corresponding rotary position in pivotal position that is provided with four magnetoelectric transducers 11 and requires with the feedback valve group with the valve group.
Initiatively wheel disc 15 is slidingly fitted on the output shaft of motor reducer, and its back side is equipped with axial compression spring 14 and makes initiatively wheel disc 15 flank of tooth and the applying of driven wheel disc 16 flank of tooth; Initiatively wheel disc 15 is " < img TranNum=" 73 " file=" 454094DEST_PATH_IMAGE001.GIF " he=" 15 " img-content=" drawing " img-format=" jpg " inline=" no " orientation=" portrait " wi=" 29 "/> " shape with driven wheel disc 16 profiles of tooth along the circumference developed surface, and driving and driven wheel disc 16 gear teeth relatively oppositely mesh; When driven by motor active wheel disc 15 forward rotates; The initiatively right angle minor face engagement of wheel disc 15 and driven wheel disc 16 " < img TranNum=" 74 " file=" 233831DEST_PATH_IMAGE001.GIF " he=" 15 " img-content=" drawing " img-format=" jpg " inline=" no " orientation=" portrait " wi=" 29 "/> " shape tooth, driven wheel disc 16 ability quilts initiatively wheel disc 15 drive; When manual reverse rotation follower shaft 7; Initiatively the hypotenuse of wheel disc 15 and driven wheel disc 16 " < img TranNum=" 75 " file=" 691357DEST_PATH_IMAGE001.GIF " he=" 15 " img-content=" drawing " img-format=" jpg " inline=" no " orientation=" portrait " wi=" 29 "/> " shape tooth is fitted and is rotated; Produce the initiatively spring 14 of wheel disc 15 ear end faces of end thrust compression; Initiatively wheel disc 15 is realized the transmission separation along yieldings that endwisely slip of motor reducer output shaft.
Original state.
The incomplete driving gear 6 and the follower 8a of partial gear indexing mechanism, 8b, 8c is in non-engagement state, ball valve 2,3,4 one-tenth closed conditions that follower shaft 9a, 9b, 9c connect, gas circuit A, B, C interface all are not communicated with in twos.
Connect the control operation of interface A, C (through throttling).
Make motor 13 clockwise rotate, so free wheel device active wheel disc 15 becomes the transmission engagement with driven wheel disc 16 end faces, not exclusively driving gear 6 clockwise directions revolution; Drive follower 8a revolution; So follower shaft 9a drives ball valve core 2 revolution synchronously, be installed in permanent magnet 11 on the drive sprocket axle 7 this moment when arriving 90 ° of positions, trigger first magnetoelectric transducer 12; Trigger signal is detected by system; The stall of control motor, the spool stall of ball valve 2 are on 90 ° of positions, and ball valve 2 gets into " opening " state.So the spool of airflow passes interface A-leading pipe b-interface D-ball valve 2-restriction E-leading pipe a is connected interface A-C.
Connect the control operation of interface A, B.
System start-up is dynamo-electric
ContinueClockwise rotate, through the valve core rotation of follower 8a, follower shaft 9a continuation driving ball valve 2, follower 8b is rotated simultaneously, and follower shaft 9b turns round the spool of ball valve 3 synchronously; When drive sprocket axle 7 rotates
To secondBe installed in the permanent magnet 11 of drive sprocket axle 7 in the time of 90 °
AlsoArrive second 90 ° of position, trigger second magnetoelectric transducer 12, trigger signal is detected by system, the outage of control motor, not exclusively driving gear 6 stalls; So the spool of ball valve 2 is returned to " closing " position, interface A-C path is turned off, and stops last path and connects; Meanwhile ball valve core 3 is driven " opening " position, and interface A-B becomes to connect, and gas circuit is switched to new path.
Connect the control operation of interface B, C.
System's incomplete driving gear 6 of starting electrical machinery 13 drives once more clockwise rotates, and the spool of follower 8b, follower shaft 9b, ball valve 3 continues to rotate thereupon, and meanwhile, the spool of follower 8c, follower shaft 9c, ball valve 4 rotates synchronously; The permanent magnet 11 that when drive sprocket axle 7 rotates the 3rd 90 °, is installed in drive sprocket axle 7 also arrives the 3rd 90 ° of positions, triggers the 3rd magnetoelectric transducer 12, and trigger signal is detected by system, the outage of control motor, driving wheel 6 stalls; So the spool of ball valve 3 is rotated " closing " position, interface A-B path turn-offs, and stops last path and connects; Interface B-C becomes on-state.The valve core rotation of ball valve 4 is to " opening " position, and interface B-C path is connected, and gas circuit is switched to new path.
System makes dynamo-electric 13 to clockwise rotate again, makes driving wheel 6 continue to turn over the 4th 90 ° clockwise, and follower 8c, driven shaft 9 c drive spool arrival " closing " position of ball valve 4 around here, turn-off interface B-C path, and the valve group is got back to initial position.
Manual manipulation mode.
The manually-operable power source is from the handle connecting head of partial gear indexing mechanism drive sprocket axle 7 front ends; When handle rotates counterclockwise driving shaft 7; Driving the driven wheel disc 16 of reverse free wheel device rotates counterclockwise; " < img TranNum=" 90 " file=" 505729DEST_PATH_IMAGE001.GIF " he=" 15 " img-content=" drawing " img-format=" jpg " inline=" no " orientation=" portrait " wi=" 29 "/> " shape hypotenuse flank of tooth of wheel disc 16 and 15 end teeth is fitted and is produced axial force; Promotion active wheel disc 15 pressure spring axles 13 move axially and skid; The driving wheel 6 of partial gear indexing mechanism II just breaks away from motor reducer, drives follower 8a, 8b, 8c revolution, thereby can obtain the break-make control between A, B, C interface by as above controlling said anti-order automatically.Valve group working position is discerned by the indicative mark on the indicator panel that is installed on driving wheel 6 front-end faces during manually-operable.
