Below by embodiment, and the invention will be further described by reference to the accompanying drawings.
Embodiment
Embodiment: the present invention includes integrated switching valve group, parallel partial gear intermittent drive mechanism and reverse free wheel device driving structure; Integrated switching valve group is the overall structure that valve body, 2,3,4, throttle valve 5 of three 2/2-way ball valves and pipeline connecting parts form; Parallel partial gear intermittent drive mechanism comprises a partial gear driving wheel 6, three full-depth tooth follower 8a in parallel that become 90 ° of distributions, 8b, 8c; Oppositely the free wheel device driving structure comprise two contrate tooth profiles for "
" active wheel disc 15 and the driven wheel disc 16 of shape; by a small-sized AC motor driven with retarder 13, driven; oppositely the active wheel disc 15 of free wheel device is arranged on motor 13 reducer output shafts, and driven wheel disc 16 is connected with intermittent drive mechanism drive sprocket axle 7.
The spool of 2/2-way ball valve 2,3,4 is by the follower 8a of the keyway on spheroid and partial gear intermittent drive mechanism, 8b, and 8c coordinates rotation, and throttle valve 5 manual tune are controlled; In valve body 1 inside, by opening file annular groove, drilling hole, the anterior turning circular groove stopped up at ball valve sealing also is connected with sealing obstruction endoporus passage, and these grooves and hole have formed the passage of control loop requirement.Be connected to two fluid leading pipe a, b to make up the inner deficiency be 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 the real 42 tooth imagination tooth partial gears that the number of teeth is 19 teeth that have, follower 8a, and 8b, 8c is 42 tooth all gears, velocity ratio 1:1; Three follower 8a, 8b, 8c meshes with incomplete driving gear 6 every 90 ° one, becomes " 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 a permanent magnet with magnetic shield, on valve body with the every 90 ° of positions of the circumference at permanent magnet same level position, the corresponding rotary position with the feedback valve group in pivotal position that is provided with four magnetoelectric transducers 11 and requires with the valve group.
Initiatively wheel disc 15 is slidably 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 16 flank of tooth laminatings of driven wheel disc; Initiatively wheel disc 15 and driven wheel disc 16 profiles of tooth along the circumference developed surface be "
" shape, driving and driven wheel disc 16 gear teeth relatively oppositely mesh; When driven by motor active wheel disc 15 forward rotates, active wheel disc 15 and driven wheel disc 16 "
" the right angle minor face engagement of shape tooth, driven wheel disc 16 can be driven by wheel discs 15 initiatively; When manual reverse rotation follower shaft 7, active wheel disc 15 and driven wheel disc 16 "
" the hypotenuse laminating of shape tooth rotates, and produces the initiatively spring 14 of wheel disc 15 ear end faces of end thrust compression, initiatively wheel disc 15, along yieldings that endwisely slip of motor reducer output shaft, is realized the transmission separation.
Original state.
The incomplete driving gear 6 of partial gear indexing mechanism and follower 8a, 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 interface A, C(through throttling) control operation.
Make motor 13 clockwise rotate, so free wheel device initiatively wheel disc 15 becomes the transmission engagement with driven wheel disc 16 end faces, not exclusively driving gear 6 clockwise direction revolutions, drive follower 8a revolution, so follower shaft 9a drives ball valve core 2 synchronous revolvings, now be arranged on permanent magnet 11 on drive sprocket axle 7 when arriving 90 ° of positions, trigger first magnetoelectric transducer 12, trigger signal is detected by system, control motor stalling, the spool stall of ball valve 2 is on 90 ° of positions, and ball valve 2 enters " opening " state.So the spool of airflow passes interface A-leading pipe b-interface D-ball valve 2-restriction E-leading pipe a, connect interface A-C.
Connect the control operation of interface A, B.
System starts dynamo-electric
continueclockwise rotate, continue to drive the valve core rotation of ball valve 2 through follower 8a, follower shaft 9a, follower 8b is rotated simultaneously, and follower shaft 9b makes the spool synchronous revolving of ball valve 3; When drive sprocket axle 7 rotates
to secondbe arranged on 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, controls the motor outage, 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.
The system incomplete driving gear 6 of starting electrical machinery 13 drive again 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 synchronously rotates; The permanent magnet 11 that is arranged on drive sprocket axle 7 when drive sprocket axle 7 rotates the 3rd 90 ° also arrives the 3rd 90 ° of positions, triggers the 3rd magnetoelectric transducer 12, and trigger signal is detected by system, controls the motor outage, 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 clockwise to turn over the 4th 90 °, 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, from the handle connecting head of partial gear indexing mechanism drive sprocket axle 7 front ends, when handle rotates counterclockwise driving shaft 7, drives the driven wheel disc 16 of reverse free wheel device and rotates counterclockwise, wheel disc 16 and 15 end teeth "
" shape hypotenuse flank of tooth laminating produces axial force; promote initiatively wheel disc 15 Compress Spring axles 13 and move axially and skid; the driving wheel 6 of partial gear indexing mechanism II just breaks away from motor reducer; drive follower 8a, 8b, 8c revolution, thereby can control by as above automatically controlling the break-make that described anti-order obtain between A, B, C interface.During manually-operable, valve group working position is identified by the indicative mark on the indicator panel be arranged on driving wheel 6 front-end faces.
