Boiler Mounting - Water Level Indicator

WATER LEVEL INDICATOR Function:   It is indicates the water level inside the boiler to an observer. Working:  The water of the boiler comes into the glass tube through the lower tube and the steam through the upper tube. The water then stands in the glass tube at the same level as in the boiler. Two cocks are used to control the passage of between the boiler and the glass tube while the third cock is in used to discharge some of the water from inside the boiler to see whether the gauge is in proper order or not. The glass tube is protected by means of a cover, made of specially toughened glass, which will prevent any accident that may happen due to breaking of glass tube. It is used for ordinary boilers.

Boiler Mounting - Blow off cock

BLOW OFF COCK Functions: ·         To discharge a portion of water when the boiler is in operation to blowout mud, scale or sediment periodically. ·         To empty the boiler, when necessary for cleaning, inspection & repair. ·         It is fitted on the boiler shell directly or to a short branch at the lowest part of the water space. This pipe is known as blow-down pipe. Working:   In order to operate the valve, the rectangular slot is brought in line with the passage of the body. This is possible by rotating the plug with the help of wheel. When the slot is placed in this position, the cock is opened and all the impurities, mud, sediments etc. Start flowing out of the boiler and they are removed. When the slot is brought at right angles to the passage of the body, the cock is closed. Image - Blow Off Cock Fig - Blow Off Cock...
