Abstract
The invention discloses a kind of cranks.Crank includes clamp, connecting rod and handle, and the clamp is for blocking runner；One end of the connecting rod is connect with the clamp；The other end of the connecting rod is connect with the handle.It is efficient, time saving and energy saving that the crank is easy to use, and effectively alleviates the consumption of labour.
Description
Technical field
The present invention relates to a kind of cranks.
Background technique
Butterfly valve is called flap valve, is a kind of simple regulating valve of structure, can be used for the switch control of low pressure pipeline medium
Butterfly valve refers to that closure member (flap or butterfly plate) is disk, and a kind of valve of open and close is reached around valve shaft rotation.
Valve can be used for controlling empty gas and water, steam, various corrosive medias, mud, oil product, liquid metal and radioactivity
The flowing of the various types fluid such as medium.Cutting and throttling action are mainly played on pipeline.Butterfly valve opening and closing element is a disc
Butterfly plate, in valve body around its own axis rotate, to achieve the purpose that opening and closing or adjusting.
It is current to be opened and closed hydraulic pressure butterfly valve often manually, it is time-consuming and laborious.
Summary of the invention
The technical problem to be solved by the present invention is to be opened and closed the time-consuming and laborious defect of hydraulic pressure butterfly valve manually, for this purpose, the present invention mentions
A kind of crank is supplied.It is efficient, time saving and energy saving that the crank is easy to use, and effectively alleviates the consumption of labour.
The present invention is to solve above-mentioned technical problem by following technical proposals:
A kind of crank, characterized in that it comprises:
Clamp, the clamp is for blocking runner；
Connecting rod, one end of the connecting rod are connect with the clamp；
Handle, the other end of the connecting rod are connect with the handle.
Preferably, the clamp is band iron.
Preferably, the one end of the clamp far from the connecting rod is U-shaped.
Preferably, the clamp and the connecting rod have certain angle, so that the connecting rod is close to the runner, it is not easy
Sliding.
Preferably, the runner is not the technical characteristic of the crank.
Preferably, the connecting rod is band iron.
Preferably, the clamp is bent with the connecting rod by a band iron.
Preferably, the handle is perpendicular to the connecting rod.
Preferably, being welded connecting between the handle and the connecting rod.
Preferably, being additionally provided with casing outside the handle.
Preferably, described sleeve pipe can rotate.
The positive effect of the present invention is that: it is efficient, time saving and energy saving that the crank is easy to use, and effectively alleviates
The consumption of labour.
Detailed description of the invention
Fig. 1 is a preferred embodiment of the present invention the structural schematic diagram of crank.
Fig. 2 is a preferred embodiment of the present invention the use state diagram of crank.
Specific embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to the reality
It applies among a range.
The present embodiment discloses a kind of crank for assisting being opened and closed hydraulic pressure butterfly valve, is understood referring to Fig.1 with 2, crank packet
Include clamp 11, connecting rod 12 and handle 13；
For clamp 11 for blocking runner 2, the one end of clamp 11 far from connecting rod 12 is U-shaped；One end of connecting rod 12 and card
First 11 connection, clamp 11 and connecting rod 12 have certain angle；The other end of connecting rod 12 is connect with handle 13, is also set outside handle 13
There is casing 14.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that this is only
For example, protection scope of the present invention is to be defined by the appended claims.Those skilled in the art without departing substantially from
Under the premise of the principle and substance of the present invention, many changes and modifications may be made, but these change and
Modification each falls within protection scope of the present invention.
