Description
Technical field
The utility model is related to the technical field of water-storage equipment, more particularly to a kind of special locking of valve operation handle
Device.
Background technology
Current pump-storage generator rotating speed high, Large Copacity, multi-state, add from mechanical factor, hydraulic factors and electromagnetism
The influence of factor, each position vibration of unit is big during operation, particularly turbine floor and spiral case layer equipment.Each valve vibration of spiral case layer
Seriously, because operation handle does not have locking device, valve operation handle often with vibration autorotation, causes the position of valve
Change, influence unit normally runs, while also producing noise pollution.The friction of valve operation handle in itself can only be leaned at present
Power carrys out fixed handle, or is pinioned valve handle with strap, so not only unstable, and very unsightly.
The content of the invention
For above-mentioned the shortcomings of the prior art, the utility model provides a kind of valve operation handle dedicated lock
Determine device.Position its purpose is to enable valve operation handle and valve is fixed, Locked valve aperture, prevents
There is non-artificial change in valve opening, and do not influenceed by unit, it is ensured that a kind of valve operation handle of the normal operation of unit is special
Use locking device.
In order to realize above-mentioned utility model purpose, the utility model is achieved through the following technical solutions：
The special locking device of valve operation handle, including valve and valve operation axle, are connected to by grip support support
On valve, valve operation axle locking set is connected on valve operation axle；Operation handle and lock handle are sequentially arranged on securing rod,
The lower end of securing rod is in contact through grip support support with valve operation axle locking set；
With securing rod to be welded to connect, lock handle is to be threadedly coupled with securing rod to the operation handle.
The grip support support is to be connected with ring-like support meanss in the top of 90 degree of bars at right angle.
The grip support support is fixedly connected on valve by grip support support fastening bolt.
The valve operation axle locking set is to lock set fastening bolt by valve operation axle to be fixedly connected on valve operation
On axle.
The lower end of the securing rod covers phase through ring-like support meanss and valve operation the axle locking on grip support support
Contact.
Advantage of the present utility model and beneficial effect are：
The utility model device has design succinct, and the characteristics of easy to operate, the device is free-hand in operation can be completed,
Without spanner, will not give the operation of valve increases workload, and consumable accessory is general, is easy to safeguard.The utility model device is not
Need the milling in the operating shaft of valve to bore grinding, therefore harmful effect will not be produced to the torsion strength of valve operation axle, and should
Device good appearance, practical function is that the Optimizing Reconstruction of equipment contribute to strength.
Locked valve can prevent valve opening from non-artificial change, influence occurring when aperture is set in the utility model
Unit normally runs, and can also eliminate the noise produced because valve handle shakes, and reduces valve handle shake to valve valve shaft
The harm of sealing, so as to ensure the normal operation of pump-storage generator work.
Below in conjunction with the accompanying drawings and specific embodiment, the technical solution of the utility model is described in detail.

In figure：Operation handle 1, lock handle 2, grip support support 3, valve operation axle locking set 4, valve operation axle lock
Surely fastening bolt 5, grip support support fastening bolt 6, securing rod 7, valve 8, valve operation axle 9 are covered.
Specific embodiment
The utility model is a kind of special locking device of valve operation handle, is that the spiral case layer in pump-storage generator sets
Standby improved technology, its structure as shown in figure 1,
Grip support support 3 is fixedly connected on valve 8 by grip support support fastening bolt 6 first, valve behaviour
Make axle locking set 4 to be fixedly connected on valve operation axle 9 by valve operation axle locking set fastening bolt 5, lock handle 2 passes through
The connection of securing rod 7 is arranged on valve operation axle locking set 4.Specifically operation handle 1 and lock handle 2 is sequentially arranged at securing rod
On 7, the lower end of securing rod 7 is in contact through the ring-like support meanss on grip support support 3 with valve operation axle locking set 4.
Wherein with securing rod 7 to be welded to connect, lock handle 2 is to be threadedly coupled with securing rod 7 to operation handle 1.The grip support branch
Frame 3 is to be connected with ring-like support meanss in the top of 90 degree of bars at right angle.
After installation, if desired Locked valve operating shaft 9, only need to loosen lock handle 2, and rotating operating handle 1 will be locked
In the insertion valve operating shaft of fixed pole 7 locking set 4, lock handle 2 is then screwed, such valve operation axle 9 is just firmly pinned, no
Occur loosening again and valve opening occurs the phenomenon of ANOMALOUS VARIATIONS.If desired for operation valve 8, it is only necessary to which rotate counterclockwise locks hand
Handle 2, then rotate counterclockwise operation handle 1, securing rod 7 is extracted from valve operation axle locking set 4, it is possible to operation valve
Door.It is free-hand to complete without instrument during the operation of this device.
As in Figure 2-4, the effect of operation handle 1 is in the utility model：The operation handle that turned clockwise during vertical view 1,
Securing rod 7 is inserted in valve operation axle locking set 4 so that Locked valve operating shaft 9, prevent valve operation axle 9 loosen or
The aperture of valve 8 changes.Rotate counterclockwise operation handle 1 during vertical view, extracts valve operation axle locking set 4, i.e., by securing rod 7
Release the locking of valve operation axle 9, it is allowed to operate valve 8.
As illustrated in figs. 5-7, the effect of lock handle 2 is in the utility model：By the dextrorotation of lock handle 2 during vertical view
Tightly, lock operation handle 1, making the securing rod 7 of device operation handle 1 cannot extract from valve operation axle locking set 4.Work as valve
8 when needing operation, should be first by lock handle 2 by could rotating operating handle 1 after counterclockwise being unscrewed when overlooking.
As seen in figs. 8-10, the effect of valve operation axle locking set 4 is in the utility model：By operation handle securing rod 7
Locking torque be transferred to the intermediate member of valve operation axle 9, be fixed on valve by positioned at the screw rod of 90 ° of the two of direction M10
In operating shaft 9.When operation handle securing rod 7 is inserted from above into valve operation axle locking set 4, valve 8 does not allow operation, only
Valve 8 could be operated when operation handle securing rod 7 is extracted from valve operation axle locking set 4.
As figs 11-13, the effect of operation handle supporting support 3 is in the utility model：Support operation handle 1, and
Coordinate the lock out action for completing operation handle 1 with lock handle 2.
