The supply SBMFJ-04S series password security shut-off valve

, Lock the device by the drum, blocking core assembly, the locking block, password plate, base, wrench. , Blocking core assembly, password plate, the base is relatively static and can not rotate, drum, lock block to free two-way rotation. The anti-theft device password security mechanism, the various components assembled in accordance with the procedures set password and record with a key, the drum into the random rotation of the drum more than 2/3 turn, the internal lock block lock playing chaotic. At this point, if you do not know the password, no matter how rotation and force, nor can the drum is removed from the base. Only the people who know the password and the direction of rotation of the order, in accordance with pre-set direction of rotation to a scale and a scale drum reverse place to another in order to remove the exposed wire spool head. The rotating wire head with a wrench will be able to open (or close) the gate valve clockwise turn, counterclockwise to open. Work is completed before the drum into the original state, and more than 2/3 turn to rotate anti-theft. When the device is first installed, the default password is set, can be installed directly. Such as production requirements change the password, turn the block core assembly will be able to form a new password, the password program must be set in accordance with the working principle of the steps. Remember password After installation, be sure the password ring removed custody, for later use.
