The utility model advantage compared with prior art is:
One, at the input password, cipher lock is carried out getting final product operated valve after release, need to be by instrument, it is more convenient to use;
When two, cipher lock locked, valve handle was in idling conditions, avoided damaging because excessive operation causes coded lock device;
Three, integrally-built encapsulation is better, and anti-destructive is stronger, further improves the Security of valve;
Four, the cipher lock place end of lock tube is provided with protecting cover, both can waterproof and dustproof, extend the working life of cipher lock, and can hide protection to cipher lock again, the destroyed possibility of reduction cipher lock.
