Padlock pins set lever and manual nut, is difficult for maloperation.
Also comprise scale 5, described scale 5 comprises chi body 51 and chi handle 52, and in a tubular form, described scale 5 is set on described manual actuation part 42 and between described handwheel 41 and nut 112 by chi body 51 described chi body 51. Scale is arranged between handwheel and manual nut, ensured valve actuator manually with electricity, gas, hands-off position while surging.
Also comprise bitch chain 6, packing ring 8 and clamp nut 92, described packing ring 8 is connected to the outer end of described locking nut 91 by clamp nut 92; Meanwhile, packing ring and clamp nut are set on bearing pin;
The outer end of described chi handle 52 is provided with chain hole 1, and described packing ring 8 is provided with chain hole 2 80, and described bitch chain connects Yi Helian hole, described chain hole two. Bitch chain connects scale and packing ring, has ensured the function of scale, has avoided the loss of scale.
The cross section of described chi body 51 is rounded or semicircle, when rounded, be directly set on screw rod and (handwheel need to be opened, then, be set on screw rod); When semicircular in shape, similar circle spoon, is close to screw rod; Then, rotate fixed ruler body by handwheel.
In the present invention, the control principle of scale is:
The scale method that to be maintenance personal require according to code is set, and the height of chi body is as the criterion and accurately processes to the distance between the end face of nut 112 with the bottom surface of handwheel 41. Scale be site operation personnel to operations staff and other departments after operated by handwheel valve, recover with scale that handwheel prepares.
When the site operation personnel of operations staff and other departments is after operated by handwheel valve, recover handwheel time, only need to rotate handwheel, the circle spoon part of scale is close to screw rod, then is close to toward backspin handwheel to the upper surface of bottom surface and scale; Then, pull set lever, screw rod is clamped.
Scale arranges and pins handwheel by the height calculating, and electricity consumption, gas, the operation of surging are verified, prevent that measurements and calculations from making a mistake. Method is electricity consumption, gas, surges and control by valve wide open, complete shut-down respectively once, in the upper and lower position of valve effective travel, i.e. standard-sized sheet/complete shut-down position of valve, check that whether handwheel is stressed, if handwheel can easily shake 1/4 circle, do not stress, can think that arranging is correctness; If there is a position stressed, there is problem with regard to explanation scale, need reset. In addition, electricity, gas, liquid operation can also record valve stroke value, and compare with the stroke value that handwheel records, if two-value is inconsistent, the reason there are differences is that thrust is inadequate or valve internal has bite or the bending of axle system, first process extremely, then carries out subsequent operation again.
In the time confirming that handwheel scale resets, be designated as the chi height of this this scale of valve actuator to the distance between handwheel bottom surface with nut end face, and old scale and new scale height are compared, if the new scale height of old scale aspect ratio is long, need only be sent machine to add workshop planer and be used highly repairing as continuing after new high degree, if old scale aspect ratio new high degree is short, can only again be processed one, old scale must be taken from scene, can not use again.
Operation principle of the present invention is: in the time that valve actuator needs are manual, take off the padlock 11 that pins set lever 2 and manual nut 1, rotate counterclockwise set lever 2, cancel the state of holding tightly, between handwheel 41 and manual nut 1, take off scale 5, rotate handwheel 41, reach the position of controlled valve executing agency; After manually completing, rotation manual mechanism 4 returns to the position that scale 5 is adjacent to handwheel 41 and nut 112, clockwise rotates set lever 2, holds screw rod tightly, pins set lever 2 and manual nut 1 with padlock 11, and whole manual operation finishes. If enclasping force is excessive or too small, can adjust the locking nut on bearing pin 7, reach and hold optimum state tightly.
