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...

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 Mountings - Dead Weight Safety Valve

DEAD WEIGHT SAFETY VALVE Function:- A valve is placed upon a valve seat that is fixed upon a long vertical pipe having a flange at the bottom for fixing at the top of the boiler. Suspended at the top of the valve is the weight carrier that carries cast iron rings. The total weight must be sufficient to keep the valve on its seat against the normal working pressure. When the steam pressure exceeds the normal limit, it lifts the valve with its weight & the excess steam escape through the pipe to the outside. This valve is used only with stationary type of boilers. It is the most elementary type of safety valve. The objection to dead weight safety valve is the heavy weight that has to be carried.
