Abstract

The utility model relates to a lock control ball valve, which belongs to the technical field of valve component parts. The utility model has the structure that an outer sleeve wall of a valve cock is provided with a lock sleeve barrel, and a lockset can slide into the lock sleeve barrel. The inner wall of the lock sleeve barrel is provided with an annular groove, a lock tongue of the lockset can be inserted into the annular groove. The utility model has the advantages that an effective control medium is provided for public institutions and managements, and the effective allotment and transportation of heat, gas and water is realized. Because the valve cock is in the sleeve barrel, and thus, the erosion and the destruction of the external environment can be avoided.

Description

Lock controlled ball valve

The utility model belongs to the valve part technical field.

At present, general pipeline valve does not all have protection or safty device, and the spanner of control valve switch revolves handle and other switching device, outside being exposed to fully.The pipeline valve in the building particularly, anyone can arbitrarily open or close, and causes and big trouble to administration departments.

The purpose of this utility model provides a kind of Lock controlled valve.

The technical solution of the utility model is as follows:

Be fixed with lock barrel on the valve cock overcoat wall, lockset slidably inserts in the lock barrel, has annular groove at the lock barrel inwall, and the dead bolt of lockset can insert in the annular groove.

The utility model advantage is: for public service and administration departments provide very effectively control device, make heat, gas, water be allocated effectively and carry, because of bolt in sleeve, avoid the erosion and the destruction of external environment condition.

Fig. 1 is a structure cut-away view of the present utility model:

Fig. 2 is spanner structure figure of the present utility model:

Be described in detail embodiment below in conjunction with accompanying drawing:

Wherein: the 1st, valve, the 2nd, valve cock overcoat, the 3rd, lock barrel, the 4th, tapered end, the 5th, annular groove, the 6th, dead bolt, the 7th, axial bond, the 8th, locking closure, the 9th, key, the 10th, retaining screw, the 11st, spanner; The 12nd, valve cock.When unblanking with key 9, dead bolt 6 is retracted in the lock body in annular groove 5, and tapered end 4 integral body promptly can be extracted out in lock barrel 3, and socket wrench specially adapted for it wrench 11 inserts in the lock barrel 3 and vises valve cock 12 controls and open or close.Axial bond 7 on the tapered end 4 can corresponding insert in the vertical slot of lock barrel 3, like this, can make tapered end 4 when key 9 is unblanked not with key 9 co-rotation.Fixing tired silk can be fixed as one valve cock overcoat 2 and lock barrel 3 in 10 o'clock.
