Abstract
The utility model relates to a butterfly valve with a lock, which is used for cutting off an oil circuit between pipelines of oil-immersed electric transmission and transformation equipment such as a power transformer, a reactor, a high voltage switch and the like, or between an equipment body and an assembly. The butterfly valve with the lock comprises a valve body (1), a valve cover (2) and a padlock, wherein the valve cover is arranged on the valve body, and an on-position keyhole (3) and an off-position keyhole (4) are arranged on the valve cover; and the padlock is arranged at the on-position keyhole and the off-position keyhole to lock the valve cover and the valve body together. The utility model has the beneficial effects that: the butterfly valve can be operated after the valve cover is opened only by opening the padlock with a special key, accordingly, the butterfly valve can be effectively prevented from unauthorized operations, and simultaneously, the correct on-off state indication is ensured, so that the hidden danger that the butterfly valve is damaged due to wrong operations is eliminated.
Description
Technical field:
The utility model relates to a kind of butterfly valve with lock, is used between the oil immersed type power transmission and transforming equipment pipelines such as power transformer, reactor, high-voltage switch gear or blocks oil circuit between apparatus body and the assembly.
Background technique:
Butterfly valve with lock is used between the oil immersed type power transmission and transforming equipment pipelines such as power transformer, reactor, high-voltage switch gear or blocks oil circuit between apparatus body and the assembly, common butterfly valve can not lock, so can not prevent the unauthorized operation butterfly valve, so inconvenient field management, in case people's unauthorized operation butterfly valve is arranged, may cause power transmission and transforming equipment to damage.Some butterfly valve does not have the on off state sign, only with the groove of valve shaft head or the direction representation switch state of arrow, causes misunderstanding easily.Some butterfly valve does not have switching manipulation direction indication or indicates not obviously, makes the operator by the direction operation butterfly valve of mistake, can damage butterfly valve.
The model utility content:
The utility model purpose provides a kind of butterfly valve with lock, effectively prevents the unauthorized operation butterfly valve, has guaranteed the on off state indicating correct simultaneously, has eliminated the hidden danger of faulty operation damage butterfly valve, solves the problems referred to above that exist in the background technique.
The technical solution of the utility model is:
Butterfly valve with lock comprises valve body, valve gap, padlock, and valve gap is arranged on the valve body, is provided with the open position lockhole and closes the position lockhole on valve gap, and open position lockhole and position, pass lockhole are provided with padlock, and valve gap and valve body are locked together.
The beneficial effects of the utility model are: have only with special-purpose key and open padlock, just can open valve gap operation butterfly valve, effectively prevent the unauthorized operation butterfly valve, guaranteed the on off state indicating correct simultaneously, eliminated the hidden danger of faulty operation damage butterfly valve.
Description of drawings:
Accompanying drawing 1 is the utility model example structure schematic representation;
Accompanying drawing 2 is the utility model embodiment plan structure schematic representation;
Among the figure: valve body 1, valve gap 2, open position lockhole 3, position, pass lockhole 4.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
Butterfly valve with lock comprises valve body 1, valve gap 2, padlock, and valve gap is arranged on the valve body, is provided with open position lockhole 3 and closes position lockhole 4 on valve gap, and open position lockhole and position, pass lockhole are provided with padlock, and valve gap and valve body are locked together.
Increased the indication of " opening " " pass " state at the butterfly valve head, and because the special construction of rotating shaft and valve gap, if when its state does not conform to the actual conditions, valve gap is not installed, and can not lock, and has guaranteed the on off state indicating correct so simultaneously.Increased the literal and the arrow of the indication of switching manipulation direction at the butterfly valve head, guiding operation person's proper operation butterfly valve has been eliminated the hidden danger that faulty operation is damaged butterfly valve.
