The locking device for the index of 12b2bk, 12b3bk, 12b1bk level
Locking devices 12b2bk are devices of crane type and are intended for overlapping of liquid working environments in indexes of levels. They are established on water-heating and boilers, units, tanks and vessels for various liquids, including water. In any unit it is necessary for determination of level of liquid that traffic jams of both cases were established in open situation, then liquid in the index of level will stop on the mark corresponding to liquid level in a copper, the unit.
The locking device 12b2bk, 12b3bk, 12b1bk of flange accession also consists of two parts of the case - top and lower, made of brass between which viewing glass is located. For determination of level of liquid in a copper or the unit of a stopper of both cases are established in open situation, then liquid level in a gage glass will correspond to level in the unit. When carrying out a purge of system the stopper of the lower crane is established in a closed position, and a stopper of the top crane - in situation "is opened", further trial spusknogo the crane to establish a stopper quickly in situation "openly" and after a purge to return it to situation "is closed". The locking device has diameter of 20 mm and is calculated on pressure of 16 kg/cm2 and temperature from 0 to 250 degrees. Water and steam acts as working environments.
