Description

Magnetic control valve lock and key

Technical field the invention belongs to special lockset, be mainly used in control, the management of various pipeline valves, being specially adapted to that natural environment is abominable, anti-damage performance requirement height, can't (or not allowing) using the automatically controlled or demanding occasion of confidentiality, is a kind of magnetic control valve lock and key specifically.

The existing lockset of background technology mainly is meant cylinder type, the electronic type (comprising magnetic card type, computer code formula etc.) that adopts machinery, for example: conventional door lock (padlock, safety lock), strongbox coded lock, magnetic card type door lock, electronic type coded lock, finger-print type intelligence lock or the like.Undoubtedly, various locksets all play an important role in different occasions more than.But at some special environment, conventional lockset uses through changing the back reluctantly with regard to inapplicable (even can't use), can't meet the demands at all.

For example: the valve on many critical pipings of the oil pipeline in oil field, gas pipeline, chemical industry unit, just often need strictly to control, pin reliably, common practices is to adopt conventional lockset (for example: padlock etc.) add with material field Welding such as wire rope, angle bar and carry out.

But under the bigger condition of possibility abominable at environment, that destroy, conventional lockset can't meet the demands, saboteur's (steal oil, gas person) can adopt general method (smash lockset, cut off wire rope, angle bar) to destroy, and reaches the purpose of stealing oil, stealing non-ferrous metal on the valve etc. simply.

For overcoming the above problems, many oil fields have taked various ways to improve anti-destructive, but all undesirable---and not being that way is invalid, is exactly that cost is too high, can't promote the use of.If when strict fire protection requirement is arranged in environment for use again, electric power control is unallowed, and other conventional locksets can't use especially at all.

Summary of the invention the utility model is to provide a kind of magnetic control valve lock and key at the deficiencies in the prior art, and can satisfy following requirement:

(1) original valve is not done change substantially, keep the original performance of valve constant;

(2) lockset has enough survivabilitys;

(3) do not adopt electric power control, higher fire resistance property is arranged, inconvenience and the loss of avoiding field electric wiring etc. to bring;

(4) be easy to on-the-spot dismounting, good confidentiality improves theftproof performance;

(5) switch is simple, and easy operating is avoided the increase added burden to the operator.

The technical solution of the utility model is: a kind of magnetic control valve lock and key, comprise lock body, dead bolt and key, it is characterized in that described lock body comprises ring-type lock that is fixedly mounted on the valve body middle part and the lock cover that is buckled in valve body top, on the described ring-type lock outer wall more than one dead bolt hole is set, place, lock cover inwall lower edge is provided with the dead bolt mounting groove corresponding with ring-type lock dead bolt hole, the dead bolt that has magnet is installed in the dead bolt mounting groove, the dead bolt middle part is provided with the guide ring of projection, has an end of a spring to withstand on the dead bolt guide ring in the dead bolt mounting groove; Described key is for being enclosed within the annular magnetic control key of ring-type lock and lock cover bottom, and its cross section is L shaped, arranges according to the magnetic coding of magnet on the dead bolt, and opposite polarity magnet corresponding one by one with latch bolt position is set on magnetic control key vertical plane.

Described key is divided at least and can folds and hinged two joints.

Described lock cover is inverted tubbiness, is divided into up and down two joints, above a joint thinner, below a joint thicker.

The edge has the notch that can insert valve handle at the bottom of the described lock cover.

The utility model compared with prior art has many advantages and good effect:

Main summary of the invention of the present utility model is that magnetic control system and magnetic coding techniques are combined together, utilizes the adsorption property of magnet to ferromagnetic material, by special structural design, reaches the open and close control to dead bolt.Utilize the magnetic coding techniques that each dead bolt and magnetic control key are carried out polarity setting (coding).When unblanking, each magnetic code must meet the requirements, otherwise, can't open.Overcome the shortcoming of conventional lockset, realized that the nothing of lockset directly contacts, unregulated power control: be easy to on-the-spot dismounting, good confidentiality, the theftproof performance height, survivability is strong; Switch is simple, easy operating, and cost is lower.Satisfy actual needs, and produced following good effect:

1, thoroughly changing the present situation that original valve can't lock control, reduce the loss (mainly referring to valve) that causes because of destruction---this is lost in each elephant of the whole nation, and number is huge;

2, stop to be destroyed the loss of the oil that causes, gas and because of the fire damage of the bad initiation of automatically controlled fireproof performance because of valve;

3, reduce the lock control investment of open-air pipeline valve and marginal well valve;

4, reduce administrative staff's quantity and reduction workload, raise the management level.

Description of drawings Fig. 1 is the utility model magnetic control valve lock and key user mode sectional structure chart;

Fig. 2 is the I place enlarged drawing among Fig. 1.

The specific embodiment is referring to Fig. 1, Fig. 2, a kind of magnetic control valve lock and key, lock body comprises the ring-type lock 4 that is fixedly mounted on valve body 5 middle parts and is buckled in the lock cover 2 on valve body 5 tops, 3 (or a plurality of) dead bolt holes 9 evenly are set on described ring-type lock 4 outer walls, place, lock cover 2 inwall lower edges is provided with and 3 corresponding (or a plurality of) dead bolt mounting grooves 8 of ring-type lock 4 dead bolt holes 9, the dead bolt 6 that the inner has magnet 10 is installed in the dead bolt mounting groove 8, dead bolt 6 middle parts are provided with the guide ring 11 of projection, have an end of a spring 7 to withstand on the dead bolt guide ring 11 in the dead bolt mounting groove 8.

Described lock cover 2 is inverted tubbiness, is divided into up and down two joints, above a joint thinner, mainly cover on the leading screw upper end, below a joint thicker, mainly cover on the handle 1.The original handle 1 of valve can keep, and also can remove.When handle 1 kept, 2 ends of lock cover, were along having the notch that can insert valve handle 1.

Described key is for being enclosed within the annular magnetic control key 3 of ring-type lock 4 and lock cover 2 bottoms, and its cross section is L shaped, and magnet that is provided with on annular magnetic control key 3 vertical planes and the magnet 10 on the dead bolt 6 are in strict accordance with the encoding law arrangement of encoding.Annular magnetic control key 3 is divided at least and can folds and hinged two joints, is easy to carry.

On annular magnetic control key 3 and lock cover 2 three pairs of magnet 10 that magnetic pole is opposite are housed, the three magnetic pole magnetic control valve locks of making are applicable to general occasion.

On annular magnetic control key 3 and lock cover 2, many magnet 10 opposite to magnetic pole are housed, make many magnetic poles magnetic control valve lock be applicable to the valve that security requirement is higher.Magnet 10 is many more, and pole arrangement does not have rule more, and confidentiality is good more.

As can be seen, the installation of the utility model on original valve is foolproof from accompanying drawing.

Annular magnetic control key 3 just often takes off, when unblanking, simply with it around being mounted on ring-type lock 4 and the lock cover 2, adjust the position, dead bolt 6 just can be opened, and can take off lock cover 2, rotating valve handle 1 can be adjusted valve.When lock cover 2 covers on valve body 5 tops, adjust the position, each dead bolt 6 front ends insert corresponding dead bolt hole 9 on ring-type lock 4 outer walls under spring 7 effects, and handle 1 inserts 2 ends of lock cover along rotating in the notch that has.After adjusting structure design, handle 1 can remove fully, and valve---safety is better and adopt special tool (or general utility tool) adjustment.
