Abstract
A rod block typed lock controlling valve and the corresponding hydraulic pincer comprises an upper part 3 of a valve body , a valve rod 2 and a bonnet 1, which is characterized in that a taper bunch typed card bowl 4 is arranged between the bonnet 1 and a circular wedge slot of the upper part 3 of the valve body; a hydraulic clamp which is corresponding to the rod blocked typed lock controlling valve is characterized in that a prolate cuboid with a rectangle notch is arranged in the part of a clamp mouth 6 and the two horizontal sides of the rectangle notch are bilateral inclined planes and a loose axle 7 controlled by the hydraulic is integrated with the cuboid with an inclined plane in one end, providing a convenient and highly effective controlling tools for the administration section.
Description
The utility model relates to lockset and the special-purpose unlocking tool thereof that is used for valve.
Valve is installed on the pipeline, controls its state of opening or closing of living in by managerial department.Decide situation for preventing that other people from changing, must valve be locked with lockset.But existing valve lockset is general and key is supporting, and perhaps no matter who unlatching of locking back all can only be unblanked devastatingly, is not easy to the management to valve.
The design's purpose provides the kelly formula lock control valve that can open repeatedly or close after a kind of locking and the hydraulic tongs that is used thereof.
A kind of kelly formula lock control valve comprises valve body top 3, valve rod 2, bonnet 1, it is characterized in that there is annular recess in bonnet 1 tubular inwall stage casing, and axial ring-type wedge groove is arranged on the cylindrical body on valve rod 2 tops, and card bowl 4 is between the wedge groove of the annular recess of bonnet 1 and valve rod 2; The hydraulic tongs 5 that is used with kelly formula lock control valve, comprise pincers handle, switch and associated jaw portion, it is characterized in that associated jaw portion 6 for the flat cuboid of rectangular indentation is arranged, is double-sided bevel at two horizontal ends of rectangular indentation, and being subjected to the movable axis 7 of hydraulic control and the bevelled cuboid of an end is one.
The design's kelly formula lock control valve and the hydraulic tongs that is used thereof do not have in the like product lockset that generally adopts, but can more effectively implement the locking control to valve.The hydraulic tongs that is used with it provides convenience, controlling tool efficiently for managerial department.
Accompanying drawing 1 is a kelly formula lock control valve sectional view:
Accompanying drawing 2 is card bowl 4 part plan views:

Embodiment:
This kelly formula lock control valve comprises valve body top 3, valve rod 2, bonnet 1, it is characterized in that there is annular recess in bonnet 1 tubular inwall stage casing, has axial ring-type wedge groove on the cylindrical body of valve rod 2 upper ends.Card bowl 4 is between the wedge groove of the annular recess of bonnet 1 and valve rod 2; Block the circular cone shape that arc lacks that is shaped as of bowl 4, its internal diameter equals the ring-type wedge groove of valve rod 2, and the radial indentation and the adjustment hole that lack trisection with arc are arranged on its covering of the fan, and lacking on the big both sides covering of the fan at arc has pilot hole; The hydraulic tongs that is used with kelly formula lock control valve, comprise pincers handle, switch and associated jaw portion, it is characterized in that associated jaw portion is the flat cuboid that rectangular indentation is arranged, is double-sided bevel at two horizontal ends of rectangular indentation, and being subjected to the movable axis of hydraulic control and the bevelled cuboid of an end is one.
When the design's kelly formula lock control valve dispatches from the factory, will block bowl with Circlip tongs and pack in the bonnet, card bowl inside caliper is in the wedge groove of valve rod 2, and the lower edge embeds in the inboard wall groove of bonnet 1, and dispatches from the factory with the valve packing.It when the design's ball valve installs on pipeline full-gear (the valve rod flat horizontal surface is parallel to the valve pipeline axis), when the user is late for paying dues, for departmental staffs such as dim, water supply with hand with the valve rod half-twist, make the valve rod flat horizontal surface perpendicular to the valve pipeline axis, and bonnet pushed the top of valve and the card bowl top in the bonnet enters in the wedge groove of valve rod.At this moment, valve just can't be opened, and clamps bonnet pressed from both sides and just can open valve after broken as opening dedicated hydraulic that valve just must use the design.The illegal unlatching of alternate manner all can make the valve rod place leak.
It when the design's gate valve dispatches from the factory closed condition.Turn clockwise with handwheel and promptly to open valve, otherwise be rotated counterclockwise then throttle down.When being late for paying dues as the user, managerial department can push the last mouth of valve body with bonnet by above-mentioned same procedure, and card bowl top is entered in the ring-type wedge groove of valve rod, realizes the valve body locking.
