Description
Technical field
The utility model relates to valve field, in particular to a kind of environmentally friendly gate valves of encryption.
Background technique
Social now, tap water almost flows into every household through pipeline and valve, as people are to water quality
It is required that raising, the requirement to the quality of running water pipe and valve is also correspondingly improved, but existing running water pipe and valve are sudden and violent
The problem of exposing is also more and more, and wherein the dispute in the management of tap water is difficult to handle, and user not environmentally causes valve
The concern of running water secondary pollution problem, valve is juggled things on water meter before somebody's closing table reaches few friendship or even does not hand over water rate
Purpose.Valve is if it is common valve before table, then who either on or off, manager can just lose to pipe-line system at any time
Control.
Solution has been obtained in problem above in the prior art, and the environment protection type magnetic invented such as inventor encrypts plastics lock
Valve (application number: CN200820063446.9), but the invention also there is a problem that
1, magnet steel be easy by addition to magnetic unlocking tool magnetic element promotion be engaged drive block with valve rod, i.e., magnet steel without
Method forms password, and encryption intensity is lower.
2, housing is directly socketed on valve deck, is easily agitated, gate valve is caused to damage.
3, when flashboard is closed, flashboard and sealing performance when valve body apertures are poor, are easy to happen leakage.
Based on the above issues, inventor continuously improves on the basis of aforementioned invention, develops to obtain the encryption environmental protection gate valve.
Utility model content
Based on problem above, the utility model provides a kind of environmentally friendly gate valve of encryption.The utility model uses multiple magnet steel
