Description
Technical field
The utility model relates to safety valve field, and relating in particular to safety can locking-valve.
Background technique
In various pipelines, often can use valve.In prior art, a lot of valves are not locked, and anyone can switch valve, makes troubles to unified management, even can cause the accident, and brings danger.Some valve is locked, but complex structure is with high costs.
Model utility content
The purpose of this utility model is to provide a kind of safety can locking-valve, is convenient to management, ensures safety, and reduces costs.
The technical solution of the utility model is that safety can locking-valve, comprise ball valve, sluice cover, be arranged on valve rod in this sluice cover, be set in the handle of described valve rod outside and be pressed in the nut on handle top, described nut top cover has locking closure, on locking closure, there is counterbore, bolt, through described counterbore and nut, is fixed in the screw at valve rod top; One side of described locking closure is cambered surface, and countersunk head is arranged at the bottom of this cambered surface, and this countersunk head is positioned at the outside of described sluice cover; The opposite side of described locking closure has arrow mouth; Described handle front end has catch, described sluice cover left side limited location post.In the time of valve closing, handle is vertical with the pipeline at ball valve place, and described countersunk head is between catch and limited post, arrow mouth is positioned at limited post top, and now handle cannot rotate, except administrative staff, other people cannot change the working state of valve, are conducive to unified management and safe handling.Use Speical screwdriver rotating bolt, unload locking closure, handle is forwarded to parallel with the pipeline at ball valve place, locking closure is buckled on valve rod, and the sensing of arrow mouth is parallel with the pipeline at ball valve place, then locking closure is fixed on valve rod with bolt, now valve is in open mode, due to locking closure do not have limited, handle band ovable valve stem rotate, can open or close valve.With respect to existing valve, simple in structure, reduce cost.In the technical program, one of them parts that described ball valve is valve.
Further, in described counterbore, be arranged with packing ring, need firmly ability compressing tablet, be convenient to locking closure and on valve rod, fix more firmly.Be convenient to unified management, avoid having an accident, use safer.
Further, between locking closure and valve rod, there is pad.Pad blocks bolt, prevents that bolt from coming off from counterbore, does not need to unload completely locking closure, only need to rotate locking closure, then buckle, and tight a bolt, and has just changed the working state of valve, simple to operate.
Further, quincunx notch is arranged at bolt top.Only have administrative staff just can turn on described bolt, guarantee unified management and use safety.
Beneficial effect: when after valve closing, countersunk head is between catch and limited post, and arrow mouth is positioned at limited post top, and now handle cannot rotate, and except administrative staff, other people cannot change the working state of valve, are conducive to unified management and safe handling; Safety is can locking-valve simple in structure, has reduced cost.

Embodiment
Below in conjunction with accompanying drawing, preferably embodiment of the present utility model is described in further detail:
Referring to Fig. 1 to 4, safety can locking-valve, comprise ball valve 1, sluice cover 2, be arranged on valve rod 3 in this sluice cover 2, be set in the handle 4 of described valve rod 3 outsides and be pressed in the nut 5 on handle 4 tops, described nut 5 top covers have locking closure 7, on locking closure 7, there is counterbore 13, bolt 10, through described counterbore 13 and nut 5, is fixed in the screw 14 at valve rod 3 tops; One side of described locking closure 7 is cambered surface, and countersunk head is arranged at the bottom of this cambered surface, and this countersunk head is positioned at the outside of described sluice cover 2; The opposite side of described locking closure 7 has arrow mouth 8; Described handle 4 front ends have catch 11, described sluice cover 2 left side limited location posts 12.In the time of valve closing, handle 4 is vertical with the pipeline at ball valve 1 place, described countersunk head is between catch 11 and limited post 12, arrow mouth 8 is positioned at limited post 12 tops, now handle 4 cannot rotate, except administrative staff, other people cannot change the working state of valve, are conducive to unified management and safe handling.With Speical screwdriver rotating bolt 10, unload locking closure 7, handle 4 is forwarded to parallel with the pipeline at ball valve 1 place, locking closure 7 is buckled on valve rod 3, and the sensing of arrow mouth 8 is parallel with the pipeline at ball valve 1 place, then locking closure 7 is fixed on valve rod 3 with bolt 10, now valve is in open mode, because locking closure 7 does not have limitedly, handle 4 is with ovable valve stem 3 to rotate, and can open or close valve.With respect to existing valve, simple in structure, reduce cost.In the technical program, one of them parts that described ball valve 1 is valve.
