Abstract
The utility model relates to a valve with a lock device, which is composed of a valve body and a valve rod. The utility model is characterized in that a handle on the top end of the valve rod is removed, and a concave slot is arranged on the top end of the valve rod to be used as a lock rod; a night lock body is additionally arranged on the outer side of the valve rod, and the valve can be locked and can not be optionally opened or closed.
Description
The utility model relates to a kind of valve, especially a kind of valve that can pin that is used on hot and cold water, coal gas, the wet goods pipeline.
At present,, generally all do not have lock, all be provided with handle, be convenient to operation on the top of valve rod with the valve of the various pipelines of what.If coal gas stops because of certain reason newspaper, managerial department can only take the coal table, is adding on the pipeline on the plug.If water, oil-piping are wanted to close down local water or oil because of certain reason, also valve can only be tied with rope, add a lead sealing again or make a little metal bucket valve is buckled well, locked little metal bucket again.These stop the pass measure and more or less have destructiveness, and troublesome poeration.
The purpose of this utility model overcomes the deficiency of above-mentioned prior art and provides a kind of simple to operate at what, and the pass stopping time does not have destructiveness, safe and reliable again locking-able valve.
The purpose of this utility model can reach by following measure: a kind of locking-able valve, and it is made up of valve body 1 and valve rod 2, and its feature is removed handle on what valve rod 2 tops, opens a concave groove 4 as locking bar, adds a pin tumbler lock body 3 at it.
The utility model can also reach by following measure: establish a lock hat 7 below a kind of locking-able valve, lock body 3, the upper end of valve rod 2 is provided with operation side 5 below the concave groove 4, and lock hat 7 is provided with one and is preced with the screw rod 6 that screw thread joins with locking.
Compared with the prior art the utility model has following advantage: open a concave groove as locking bar by what in valve stem tip, and adding a pin tumbler lock body, valve can be locked, and can be by random not opening or closing.When coal gas newspaper stops or water, oil need to close the stopping time, only need open the lock back and close that to decide valve locked again; When needs, can open the lock Open valve again, avoid the destructive procedure mode, reduce trouble, improve working efficiency.
Appended drawings is a kind of structural representation of locking-able valve

The 5-side of operation 6-screw rod 7-locks hat
Describe the utility model in detail below in conjunction with accompanying drawing
Common valve has Ball valve, flashboard valve, shutoff valve, flange valve etc. at present, and various valves all can be transformed into locking-able valve.Accompanying drawing is to be example with the shutoff valve, on valve rod 2, add a transformation and open a concave groove 4 as locking bar, add a pin tumbler lock body 3 in its outside, be provided with a lock hat 7 below the lock body 3, after pin tumbler lock body 3 inserted locking bar, the bullet tongue of lock body 3 inserted the concave groove locking, and lock hat 7 covers the upper end of valve body 1, the whole valve rod that exposes valve body is all covered, make valve be in a kind of lock state.At this moment lock body can rotate around locking bar, if rotary screw 6 withstands valve body 1, can prevent that lock body from rotating.In the upper end of valve rod 2, be provided with an operation side 5 below the concave groove, it can be flat type.Can be positive square or rectangle, can also be six rib types, when opening lock, and can be with conventional instrument rotary valve rod, to close or to open valve.
