Background technique
Encrypting valve before the table is to be used for controlling the break-make that supplies water in the water meter upstream, China's patent No. is to encrypt valve and special spanner thereof before the utility model patent of 200520034868.X discloses a kind of effective table, the structure of encrypting valve before its effective table is shown in figure one: comprise valve body 11, gate valve mechanism 12, the locking-valve device, described locking-valve device comprise the magnetic support 17 that is connected with the valve rod 14 of gate valve mechanism 12 by driving pin 13 and at least one group be communicated in the turncap 16 and magnetic support 17 in lockhole and interior lock pearl assembly, be installed in the dust-proof cover 21 outside the magnetic support 17, on magnetic support 17, be provided with pin-shifting hole, lock pearl assembly comprises the spring 18 that is positioned at the lockhole bottom, the shotpin 19 at middle part, the magnet steel 20 on top, shotpin 9 upper-end surfaces are higher than the junction plane of turncap 16 and magnetic support 17, magnet steel 10 external diameters are greater than turncap 16 lockhole apertures, in addition the spanner internal fixation of special use have with magnetic support 17 in the powerful magnet steel that matches mutually of magnet steel 20, the pole polarity of the adjacent ends of magnet steel of two pairings is identical; Lock pearl assembly before the principle of utilizing magnetic pole peer to repel each other like this will be shown with spanner in the valve pushes away locked position, rotating spanner, can open or lock valve, the principle of unblanking of valve is difficult for being grasped before this model utility table, make management safer, but, use rear spring easily to lose efficacy for a long time owing to adopted spring in its lock pearl assembly, causing encrypting valve can not normally open and close, and its durability is relatively poor.
The model utility content
The purpose of this utility model is to overcome the above-mentioned shortcoming of prior art, and a kind of encryption valve is provided, and its durability is better.
The purpose of this utility model is achieved in that
A kind of encryption valve, comprise valve body, gate valve mechanism, the locking-valve device, wherein the locking-valve device comprises the magnetic support of the band pin-shifting hole that is connected with the valve rod of gate valve mechanism by driving pin, in at least one group of turncap that is arranged on gate valve mechanism and lockhole in the magnetic support and the lock pearl assembly in the lockhole, it is characterized in that described lock pearl assembly comprises the static magnet steel that sets gradually from bottom to up, plug, the slip magnet steel, wherein plug and lockhole are interference fit, reach the purpose of fixed static magnet steel, the upper-end surface of plug is lower than the highest of lockhole in the turncap, the height of slip magnet steel is greater than the upper-end surface of the plug height between the highest of lockhole to the turncap, and less than the height of magnetic support part lockhole, the end pole polarity that static magnet steel is adjacent with the slip magnet steel is different;
As further optimization of the present utility model, in the described turncap that is arranged on gate valve mechanism and the lockhole in the magnetic support and the lock pearl assembly in the lockhole be two groups or more, they are that the center evenly distributes with the axis of valve rod;
Working procedure of the present utility model is: the finger on will be with the encrypting valve supporting special spanner inserts in the pin-shifting hole on the magnetic support, because spanner is provided with the powerful magnet steel corresponding with magnetic support lockhole position, the polarity of the adjacent end of slip magnet steel is different in powerful magnet steel and the lockhole, can overcome static magnet steel up picks up the slip magnet steel the suction of slip magnet steel, the magnet steel that slides this moment is inhaled into the lockhole that is arranged in the magnetic support part, remove locking, this moment, rotating spanner can be opened valve; Magnetic support is rotated in place and takes away spanner, and the slip magnet steel moves down under the suction of static magnet steel, is arranged in the lockhole of magnetic support and turncap, and valve rod can not rotate, and encrypts valve and is in locking state;
The utility model has been cancelled original spring in lock pearl assembly, be difficult for losing efficacy, and its durability is better, and has cancelled dust cover, and is simple in structure, cost is lower.
