Description
Technical field
It the utility model is related to a kind of device for limiting oil-control gate valve oil pump capacity, and in particular to a kind of XFQ65-25 gate valves dress
The valve plate control lock put, belongs to industrial machinery technical field.
Background technology
At present, most of gate-valve device does not have protector, in production wellhead, the oil-out of oil storage tank, petroleum pipeline
Gate valve control point be frequently present of the phenomenon that crude oil is stolen.Due to no protector, a large amount of well mouth of oil well in field oil field,
The oil-out of oil storage tank and the gate valve control point of petroleum pipeline, because unattended for a long time, especially at night, often opened
Valve stolen, makes national wealth suffer a loss, and pollutes the environment, and some even causes the serious accidents such as fire.It is common at present
Method be to have the pinning of the handle of chain and lock handle gate valve, but criminal sawed-off chain or can still break open a lock, second, using general
Special spanner opening and closing gate valve is used alone in logical lock plus special spanner, but first has to the processing on the body of gate valve and weld a set of phase
The shield of matching, common lock, which is easily broken, to be broken, and special spanner is using off-gauge tripartite, five sides and abnormally-structured
Deng, and be easy to be copied, therefore anti-theft effect is undesirable, cost is also high.For these problems, it is therefore desirable to a kind of gate valve
Device valve plate control lock, a kind of different gate valve protector of structure type, can effectively prevent to crude oil steal and it is right
The destruction of gate-valve device.The protector possesses following function:The opening and closing that the device can be to gate valve first are carried out
Control, secondly, the device also needs have lock function to gate-valve device, i.e., the device can prevent other people to the random of gate valve
Operation, can also prevent crude oil steals phenomenon appearance.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of valve plate control lock of XFQ65-25 gate-valve devices, it
Violating the regulations or maloperation can be prevented, causes valve to stagger, open by mistake, causes valve to be closed not in place, fuel transfer pressure is too high, and destroy by rush of water valve
Pad etc. causes to ooze in valve, interior alter, runs oil etc..
To achieve these goals, the technical solution of the utility model is:A kind of valve of XFQ65-25 gate-valve devices is provided
Plate control lock, it is characterised in that the XFQ65-25 gate-valve devices mainly include:Valve rod, locking nut, handwheel, bearing gland,
