Description

The magnet valves door lock

The utility model relates to a kind of lock, particularly a kind of magnet valves door lock that uses when having the heating and supplying water system reform now that is applicable to.

At present, heating charging is the hard nut to crack of puzzlement China various places heating unit always, some illegal users often refuse to pay relevant heating cost with all excuses, have seriously influenced the economic benefits of heating department, thereby have made heating work normally to carry out.Though some heating unit has taked certain measure, for example installs locking valve additional, the disposable anti-structural design that opens of the many employings of this valve needs to use special tool to open, and valve body itself can not be reused, so user cost and construction cost height.In addition, water system also exists similar problem.

The purpose of this utility model is simple in structure, and is easy to use, and " promptly open promptly and supply " " promptly lock promptly stops " can reusable magnet valves door lock.

The purpose of this utility model is achieved in that it comprises lock nut and lock core, and lock nut is the cylindrical cavity of hollow, the sealing of one end, and the other end is open, and lock core is a cylindrical body, slidably in the cylindrical cavity of lock nut; Lock nut closed end and lock core facing surfaces are provided with blind hole, lock core is provided with pin with matching with one side, offer annular groove on the inwall of lock nut cylindrical cavity, lock core cylindrical body side is provided with blind hole, by spring bar magnet is installed in it, bar magnet can slide in the groove on the lock nut; The lock core middle part offers internal thread that matches with ball valve body and half through hole that cooperates valve rod; The pin of lock core is when blind hole on the lock nut cooperates, and the blind hole of lock core side is positioned at the top of lock nut groove; The lock nut open end is provided with spring ring.

In order to cooperate use of the present utility model, the utility model also comprises a kind of magnetic key, it adopts the hollow cavity structure consistent with the lock nut profile, its cavity wall interior with lock nut annular groove equal-height position be embedded with lock core on bar magnet number and distributing position is identical and polarity is identical magnet.

When using the utility model, at first opening state (pin of lock core upper end inserts in the blind hole on lock nut top) by internal thread in the middle part of the lock core with the utility model rotation set on ball valve body, the valve rod of ball valve body stretches in the half interior through hole of lock core, carry lock nut then, lock core in it glides, bar magnet in the lock core blind hole is at the annular groove that snaps in naturally under the effect of spring on the lock nut inwall, at this moment, in any case rotation lock nut, lock core all is in the relative fixed state, thereby unwarranted user can't operate the valve rod that links to each other with lock core, and then has realized the locking to ball valve itself; When validated user uses, corresponding magnetic key is enclosed within lock nut, slowly drive lock nut clockwise or be rotated counterclockwise, because to sink into the polarity of the interior bar magnet of lock nut annular groove identical for card on the magnet in the magnetic key body and the lock core, under the effect of magnetic repulsive force, in the bar magnet retraction blind hole, lock nut sinks, lock core moves on relatively, thereby make the pin of lock core upper end insert the interior blind hole of lock nut again, revert to opening state, this moment, lock nut can make lock core produce interlock, thereby it is taken off from ball valve body, make valve rod be exposed to the outer corresponding adjustment work of finishing fully.

In sum, in the utility model using process, need not any destructive procedure, and outer surface there is not any lockhole, be difficult for being damaged by artificial the obstruction, therefore, the utility model is simple in structure, easy to use, and reliability, suit in existing heating and supplying water system reform process, to be widely adopted.

Below in conjunction with accompanying drawing in detail the utility model is described in detail.
