Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of magnetic lockable valve.
Background technique
Valve rod and lock nut are all to be fixedly connected with by shop bolt, and valve rod is with bonnet in existing magnetic locking valve
Axially position, lock nut is also equivalent to by forming axial restraint between shop bolt and bonnet, then in order to make positioning pin
Valve rod and lock nut can be fixedly connected with by nail, just need to carry out the positioning of positioning pin in the outer side perforating of lock nut in processing, from
Outside carries out punching and is easy to make to leave wound on lock nut, and entire valve is also direct exposure in whole lock nut after the assembly is completed
Outside, it is so just easy to that other people is enable to carry out malicious sabotage to valve from punching place of lock nut, so as to cause valve
Door failure.
For this purpose, the applicant is it is proposed that excessively a kind of magnetic locking valve [application number：201720043252.1], it includes valve
Body, the bonnet for being connected to valve body upper end and the lock nut being socketed on bonnet are equipped with magnetic lockable mechanism between bonnet and lock nut,
