In seat, magnetic support is equipped with square hole corresponding with square toes, and the lower end of valve rod is connected with flashboard, is equipped with two in the upper end of magnetic support and dustproof cover
A rotation pin hole, it is characterised in that coaxial main lockpin hole and at least one auxiliary lock pin there are two being all provided in magnetic support and turncap
Hole, two main lockpin holes are arranged with the axisymmetrical of valve rod, assist the spacing of lockpin hole and two main lockpin holes unequal, are revolving
It is equipped with reset spring in the main lockpin hole of cap and in auxiliary lockpin hole, is equipped with main encryption magnetic in the main lockpin hole of magnetic support
Steel is equipped with secondary encryption magnet steel in the auxiliary lockpin hole of magnetic support, and main lock is equipped between reset spring and main encryption magnet steel
Pin, main lock pin are located in the main lockpin hole of magnetic support and turncap simultaneously；Secondary lock is equipped between reset spring and secondary encryption magnet steel
Pin, secondary lock pin are located in the auxiliary lockpin hole of magnetic support and turncap simultaneously；The diameter of secondary encryption magnet steel is less than main encryption magnet steel
Diameter.
Magnet steel in private key matched with the utility model, the arrangement of arrangement and fully sealed multi stage enciphering valve
Mode is identical, pushes the main encryption magnet steel and secondary encryption magnet steel of enciphering valve open by the magnet steel in private key, realizes unlock；By
Unequal in the spacing and diameter of main encryption magnet steel and secondary encryption magnet steel, for all magnet steel in abnormity setting, encryption is good,
It is not easy the advantage for being cracked and being copied by other people, safety can be improved, avoids enciphering valve stolen；
The radial distance of the secondary encryption magnet steel and valve rod axis is less than master as a further improvement of the utility model,
Encrypt the radial distance of magnet steel and valve rod axis；The magnet steel setting of radial Unequal distance can further improve encryption；
As a further improvement of the utility model, in the interface of magnetic support and dustproof cover, the interface of valve rod and magnetic support
And the interface of valve body and turncap is equipped with sealing ring；Hermetically sealed effect can be achieved；
In conclusion the utility model has the advantages that the set-up mode of magnet steel is not easy to be cracked and copied by other people, can mention
High security avoids enciphering valve stolen, and good airproof performance.
Detailed description of the invention
