Abstract
The utility model discloses a kind of theft-proof hand wheel of flap type, the theft-proof hand wheel is made up of two different concentric circles of diameter, it is connected on the outside of the inner side concentric circles less with diameter of the concentric circles being relatively large in diameter by three fixtures, the fixture is provided with regulating bolt with the concentric circles junction being relatively large in diameter；The fixture is provided with locating piece with the less concentric circles junction of diameter.By special regulating bolt come adjust with locked handwheel, avoid common handwheel anyone the problem of can operating.When theft-proof hand wheel needs switch, it is necessary to could be operated by professional spanner, prevent handwheel to be misused, there is the features such as theftproof performance is more preferable, and switch is easily, sealing effectiveness is stable, service life is long.
Description
Technical field
Technical field of petrochemical industry is the utility model is related to, more particularly to a kind of theft-proof hand wheel of flap type.
Background technology
It is of the prior art manually antitheft flap type be oil field pipe a kind of professional component, it be arranged on wellhead assembly and
In throttle well killing manifold.It is left and right ends face ring flange that Yuanping City's plate valve is connected with pipeline, 8 circular holes are uniformly distributed on ring flange,
" O " type groove on ring flange contact plane, in addition airtight and watertight padding and then fastened by 8 screw bolt and nut.The disadvantage of this connection method
It can take flap type away as long as end is fixing nut, the disassembling bolts on the ring flange of left and right and cause unnecessary loss.
The content of the invention
The purpose of this utility model is to provide a kind of theft-proof hand wheel of flap type.
The purpose of this utility model is realized by following measures：
A kind of theft-proof hand wheel of flap type, the theft-proof hand wheel are made up of two different concentric circles of diameter, the diameter
Be connected on the outside of less with the diameter concentric circles in the inner side of larger concentric circles by three fixtures, the fixture and diameter compared with
Big concentric circles junction is provided with regulating bolt；The fixture is provided with positioning with the less concentric circles junction of diameter
Block.
The angle formed between three fixtures is identical.
The different concentric circles of described two diameters and fixture and regulating bolt are the material of stainless steel.
It is pass when the theft-proof hand wheel rotates clockwise.
It is to open when the theft-proof hand wheel rotates counterclockwise.
A kind of theft-proof hand wheel of flap type described in the utility model：Adjusted and locked hand by special regulating bolt
Wheel, avoid common handwheel anyone the problem of can operating.When theft-proof hand wheel needs switch, it is necessary to pass through professional spanner ability
Operation, prevents handwheel to be misused, and has theftproof performance more preferable, the spy such as switch is light, sealing effectiveness is stable, service life length
Point.
Beneficial effect：
A kind of theft-proof hand wheel of flap type described in the utility model, simple in construction, cost is low, easy to adjust, also simultaneously
It is more preferable with theftproof performance, switch the features such as light, sealing effectiveness is stable, service life is long.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the theft-proof hand wheel of flap type provided by the utility model.
Embodiment
A kind of theft-proof hand wheel of flap type provided by the utility model, the theft-proof hand wheel is by different concentric of two diameters
Circle composition, the inner side concentric circles outside less with diameter of the concentric circles being relatively large in diameter are connected by three fixtures, institute
State fixture and regulating bolt is installed with the concentric circles junction being relatively large in diameter；The fixture connects with the less concentric circles of diameter
The place of connecing is provided with locating piece.
The angle formed between three fixtures is identical.
The different concentric circles of described two diameters and fixture and regulating bolt are the material of stainless steel.
It is pass when the theft-proof hand wheel rotates clockwise.
It is to open when the theft-proof hand wheel rotates counterclockwise.
A kind of theft-proof hand wheel of flap type described in the utility model：Adjusted and locked hand by special regulating bolt
Wheel, avoid common handwheel anyone the problem of can operating.When theft-proof hand wheel needs switch, it is necessary to pass through professional spanner ability
Operation, prevents handwheel to be misused, and has theftproof performance more preferable, the spy such as switch is light, sealing effectiveness is stable, service life length
Point.
