How do you test a safety valve of a Boiler?
Raise the pressure in the boiler until the valve relieves and note the pressure at which it does so.
On a high pressure boiler the pressure gauge could be graduated in?
2 times the pressure at which the safety valve is set.
Why is to safety valve mounted on boiler drum?
the safety valve is mounted on the top of drum because, if the water level in boiler decreases a certain value, the temperature gets increased in water drum because of lack of water. So, increase in temperature result in high pressure in steam drum, as the safety valve is designed to withstand a certain pressure, after a cetain pressure, the safety valve is removed by high pressure of steam. this is why the safety valve is mounted on top of boiler drum. +++ Shall we sort out that lot? That answer is wrong. Its only link with water-level is that the valve has to be above the water anyway. If the boiler runs dry the safety-valve will not protect it. The safety-valve is there to prevent the steam pressure rising to a potentially a dangerous level. It is set to open at the boiler's designed working pressure.
How do set the lifting pressure of boiler safety valve?
The lifting pressure is set by turning the adjusting nut on top of the valve.
What actions would be required if the safety valve was popping and the steam pressure indicated 30 psi on the boiler?

How is boiler spring loaded safety valve works?
when the pressure increases over the maximum allowable working pressure of the vessel, the valve will open to protect against overpressure.
What is a safety valve gag on a boiler?
