The nozzle stall control stalk 29 of control mechanism 4 is provided with pull bar locating bush 37 away from an end of governor lever 32, be provided with at least two grooves 38 that length is different in the pull bar locating bush 37, the little key piece 39 in location is housed on the nozzle stall control stalk 29, locatees in the groove 38 in the little key piece 39 insertion pull bar locating bushs 37.

Nozzle vertical rotation transmission scheme:

High pressure liquid stream drives spiral impeller 5 high speed revolutions, give worm screw 15 down by impeller drive disk assembly 6 with transmission of rotation, worm gear 13 rotates under following worm screw 15 drives and its ingear, following worm gear 13 will horizontally rotate and be transferred to main shaft 2 by horizontally rotating cover 11, it is speed governing fork 16 that the rotation of following worm screw 15 is set the 17 unidirectional transmission forks that promote to go up on the worm screw 14 ahead by transmission, motion is transferred to last worm gear 12 with last worm mesh, last worm gear 12 drives and double end screw collar 9 ingear nut block 21 rotations back and forth, make double end back and forth screw collar 9 make straight-line motion up and down, main shaft 2 and double end screw collar 9 usefulness movable heads back and forth are connected, the transmission straight-line motion, horizontally rotating by key of main shaft 2 directly is transferred to nozzle holder, straight line moved and is transferred to gear 25 about the tooth bar 24 of its lower end was incited somebody to action, gear 25 is sleeved on the vertical rotation axle 26 of nozzle 8, realizes the vertical rotation of nozzle.Transmitting ratio between last worm screw 14 and the following worm screw 15 is determined by the effective angle f obliquity of the speed governing fork 16 on the last worm screw, the maximum effective angle f obliquity of this mechanism is 12 °, and effective angle f obliquity can carry out the automatic or manual adjustment by regulating mechanism 4, thereby realizes the adjusting and the control of the vertical rotating speed of nozzle.

Nozzle vertical rotation control mechanism scheme:

Be provided with the actuating spindle 28 synchronous with nozzle 8 vertical rotation in the control mechanism 4, the rotation of actuating spindle 28 by last worm gear 12, is transmitted by gear bevel gear 47, large bevel gear 48, miniature gears 49, gear 50.Automatic speed regulation cam 30 and stall cam 31 are housed on the actuating spindle 28, automatic speed regulation cam 30 its curves can design by the washing of tanks arts demand, and can change automatic speed regulation cam 30 as required, the limiting stopper of using when stall cam 31 is provided with stall block 40 and adjusts stall block 40 angle positions 41.

The control of nozzle vertical rotation speed is that automatic speed regulation cam 30 and manual governing cam 33 are arranged, and pushes down governor lever 32 respectively at governor lever 32 two ends, is provided with the guided bearing point that can move up and down in the middle of the governor lever.Automatic speed regulation cam 30 and manual governing cam 33 press lever by the pressure head of governor lever 32 respectively, force governor lever 32 center support axles 54 to move up and down, change the effective angle f obliquity value of speed governing fork 16 immediately, because speed governing fork 16 is lived governor lever 32 at next vertical compression of effect of second spring 42, make 32 liang of pressure heads of governor lever push down automatic speed regulation cam 30 and manual governing cam 33 always, realize the speed governing purpose.Automatic speed regulation cam 30 rotates synchronously with nozzle vertical rotation axis 26, the instant control of its convex surface height governor lever 32 ram position are implemented speed governing, during manual governing, unclamp lock screw 46 earlier, rotate rotation hand wheel 45, manual governing cam 33 is forwarded to screw screw 46 again behind the position that needs and get final product.

Be provided with the nozzle stall control stalk 29 of multiple function in the control mechanism 4, on the nozzle stall control stalk 29 stop collar 34 is housed, little key piece 39 and spring 35, nozzle stall control stalk 29 is in locating bush 37, can spur and transposition, work timing position cover 34 is withstood by lever-type rotational support 36, when the stall block 40 of stall cam 31 puts in place, stall block 40 promotion rotational support 36 are left the stop collar 34 on the nozzle stall control stalk 29, nozzle stall control stalk 29 is moved down rapidly under spring 35 effects, promote governor lever 32, force effective angle f obliquity value≤0 of speed governing fork 16, realize that nozzle 8 stops in the rotation of vertical direction.

Pull bar locating bush 37 endoporus of nozzle stall control stalk 29 are provided with four not grooves 38 of same-action, the little key piece 39 in location is housed on the nozzle stall control stalk 29, the 29 pulling transpositions of nozzle stall control stalk can enter in the different groove 38 the little key piece 39 in location, reach different control purposes.(1) after the little key piece 39 in location enters in the longest not groove, when nozzle stall control stalk 29 moves down, promotes speed governing fork 16, make its effective angle f obliquity value≤0, realize stall; (2) the little key piece 39 in location enters in the short slightly groove, be the speed control groove, when generation nozzle stall control stalk 29 moves down, the instant speed governing fork 16 that promotes, make its effective angle f obliquity value transfer to new setting value, like this nozzle 8 vertical rotation speed with autostable in new setting value (this moment speed automatically regulating still effective in manual regulation function); When (3) the little key piece 39 in location entered in the shortest positioning groove of locating bush 37, nozzle stall control stalk 29 can't move down, and does not promptly implement automatic stall of allocation or speed changing function; (4) as in washing of tanks, stopping the vertical rotation of nozzle immediately, then but the hand rotation control stalk 29, make the little key piece 39 in location enter the through slot of locating bush 37, on the stop collar 34 on the nozzle stall this moment control stalk 29 breach is arranged, make nozzle stall control stalk 29 lose support, move down rapidly, realize stall.Rotate as recovering, only need pull-up nozzle stall control stalk 29 and rotate, will locate little key piece 39 and enter first groove and get final product.

The position of the stall block 40 on the stall cam 31 can be adjusted by adjusting hand wheel 43, method of adjustment: to rotate with handle earlier to go up worm screw 14, make the angle position that nozzle 8 forwards to needs stall, determine by viewing angle indicator stem 52, after angle puts in place, unclamp locking piece 44, by backward rotation adjusting hand wheel 43, drive stall cam 31 and rotate, till the position stop on the stall cam 31 41 is blocked, tighten locking piece 44 this moment again.
