Specific implementation mode
The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Referring to Fig. 1, the embodiment of the present invention includes：
A kind of more turning valve manual driving devices shown with valve location, including：1 He of intermeshing bevel gear wheel
Bevel pinion 2, the position indication 3 on the gear shaft of the bevel pinion 2, the position indication 3
Including：The first order that intermeshing fixed annulus 4, planetary gear 5, transmission gear 6 form in indicator shell
The second level transmission mechanism that transmission mechanism and fixed annulus 4, second level transmission gear 8, movable internal gear 7 form, it is described
Movable internal gear 7 be mounted in movable internal tooth fringing 9 and with movable 9 synchronous rotary of internal tooth fringing, the activity internal tooth edge
Pointer 10 is installed on side 9, there is marking aperture scale and position of the switch label 11 on the surface of the indicator shell.
Wherein, the planetary gear 5 has 3-5, and the 3-5 planetary gear 5 is distributed on the fixed annulus 4
It is interior；Preferably, the present invention in planetary gear 5 have 4, wherein three be the identical common planetary gear of structure, one be lengthening
Planetary gear, and using the lengthening planetary gear as second level transmission gear.
Handwheel input power passes to the transmission gear in bevel gear wheel 1 and position indication 3 by bevel pinion 2
6, bevel gear wheel 1 drives bushing 12, passes through spline synchronous rotary, valve stem nut 13 and valve between bushing 12 and valve stem nut 13
Valve rod is threaded（Outside screw stem rising through handwheel type gate valve）, when valve stem nut 13 rotates, valve rod carries out promotion or downlink, to open and close
Gate valve etc. or valve stem nut 13 couple (inside screw nonrising stem type gate valve) with valve rod by axis, add flat key passing power, valve rod is not
It moves up and down.
It in the position indication 3, has used and has slowed down twice, realized large speed ratio, first order transmission is NWG type rows
Star gear drive, second level transmission are NN type Planetary Gear Transmissions.Using product type SZ-1 as class, first order NWG type planet teeth
Wheel transmission, the transmission gear number of teeth are 34, and the planetary gear number of teeth is 22, and the fixed annulus number of teeth is 78, then the transmission ratio of the first order
For 1+78/34.Second level NN type Planetary Gear Transmissions use in the planetary gear of the first order gear to be lengthened as
Secondary transmission gear, the number of teeth 22, the fixed annulus number of teeth are 78, and the movable internal gear number of teeth is 79, then the transmission ratio of the second level
For 1/ (1-78/79).Then two-stage overall ratio can reach 260.235：1.
Scale and the position of the switch, the scale of different total angles, to adapt to not specification are made on 3 surface of position indication
Valve requirement, can intuitively show the arbitrary station residing for valve.Aperture scale and the position of the switch are made with label, mutually
It is transsexual stronger.Than the valve if any two specifications, the valve rod stem nut of a valve turns round 30 turns, can be from open position to off-position, separately
The valve stem nut of one specification valve turns round 22 turns, can be from open position to off-position.Have learned that the reduction ratio of SZ-1 is 37/9, then valve rod
Nut turns round 30 turns, completes from open position to off-position, and switch total angle is 170.6；When valve stem nut turns round 22 turns, complete from opening
Off-position is arrived in position, and switch total angle is 125.1.
Present invention is disclosed a kind of more turning valve manual driving devices shown with valve location, by driving device
Handwheel at install additional position indication, in the position indication carry out two level large speed ratio deceleration, valve rod spiral shell
In the case of the rotation fixed number of turns, movement is synchronized by open position to off-position and is passed to position indication mother by valve, and
Scale is made on position indication surface, can be intuitively displayed the station residing for valve.In addition all in the driving device
Movement position installs O-ring additional, is sealed, can improve the dustproof and waterproof performance of driving device.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
