Abstract

The utility model relates to a flow rate controlling valve with a lock controlling device, which comprises a valve body, a valve core and a valve rod and the valve rod connected with the valve core passes through the valve body and is connected with a handle. A fluted disc with ratchets is arranged on the handle. A rack bar engaged with the fluted disc is fixed to a framework on the valve body. A locking device is arranged on the framework. The locking device comprises a cipher lock, a lock unlocking device and an electrical controller. The center shafts of the cipher lock and the lock unlocking device are mutually connected in a hitting manner and synchronously rotate. A motor in the lock unlocking device causes a cipher disc to rotate to an unlocking or a locking position through the center shafts. The other motor of the lock unlocking device drives a swimming ring propping against the cipher lock in the cipher lock through a lead screw. Thereby, a protruding handle arranged on the circumference surface of the swimming ring drives the rack bar to detach from the fluted disc to cause the valve to open. The utility model provides the flow rate control valve arranged at the front part of a gauge and has the advantage of strong anti-theft performance. Under general conditions, only professional persons can open the valve after the valve is closed, which causes illegal users to be incapable of stealing water, gas and fluid media in delivery pipelines.

Description

The flow control valve of control device with lock

Technical field

The utility model relates to a kind of flow control valve that is installed in conveying gas or the fluid pipeline, and especially a kind of flow control valve of control device with lock is to belong to technical field of valve manufacturing.

Background technique

Existing common valve, especially ball valve generally all are random switches, can not mandatoryly close.But for the reason of management, valve need be controlled sometimes, can not arbitrarily be unlocked, to prevent that water or gas in the delivery pipe from illegally being used, this just need load onto a locking device on valve.Existing Valve with lock, particularly the Ball Valve With Lock kind is a lot, and structure also has nothing in common with each other.It is made up of mechanical lock and ball valve two-part the patent No. for " 99254574.9 " " Ball Valve With Lock ", and it is simple in structure, and cost is low, but illegal user as long as whole lock body is removed, just can make opening of valves, so its theftproof performance is good inadequately.The patent No. is that " 03228287.7 " " novel Ball Valve With Lock " its lock body and valve are connected as a single entity, lock body center lock core connects with valve rod, this Ball Valve With Lock can't be removed lock separately, its theftproof performance improves greatly, but because processing technology complexity, manufacturing efficiency can't improve, so its manufacture cost is higher.
