Which safety valve should be set to discharge at lower pressure drum safety valve or super heater safety vlave?
The Superheater safety valve must be the lowest set safety valve on any boiler, in order that flow through the superheater is maintained.If the drum valve were set lower the flow through the superheater would be disrupted on an overpressure.
What is a safety valve gag on a boiler?
A gagging tool is used on the water drum safety valves for the pressure setting. The safety valves are gagged one by one and the blow off presure is set for the other.
Difference between set pressure and blow-off pressure?
The set pressure is the pressure at which a relief valve starts to open. When the valve is open and relieving, the pressure will be higher or lower than the set pressure, depending on the system and the valve design. That is the blow-off pressure.
What you mean by cold differential set pressure of a safety valve?
cold differential test pressure -The inlet static pressure at which a pressure relief valve is adjusted to open on the test stand. This test pressure includes corrections for service conditions of superimposed back pressure and/or temperature.
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.

Should the shut -off valves on the rear of the last trailer be open open or closed on the first trailer in a set of doubles on the middle trailer of a set of triples?
should the shut off valves on the middle trailer of a set of triples be open or closed
What is a safety valve gag on a boiler?

Which shut off valves should be open and which closed on a tractor trailer?
Closed on the first trailer in set of doubles. No on the middle trailer. No of a set of triples

What psi is the safety valve set to open on trucks?
It is set to blow off air pressure exceeding 150 psi.
Do valves in the heart let the blood travel in all directions?
No the way the valves of the heart are set up causes the blood to move in one direction only.
Trying to set the set valves on 350 which valve is the intake and which is the exhaust you have found tdc and set the 1 valves now what?
The intake valves line up with the intake runners on the intake manifold. The exhaust valves line up with the exhaust runners on the exhaust manifold or headers. With #1 at tdc you can set 1,2,5,7 intake and 1,3,4,8 exhaust valves. Rotate the engine one revolution to #6 tdc and set the remaining valves.
Pneumatic safety valves should be set to operate in excess of what psi?
It depends on the vessel or machine the safety valves are supposed to protect. If the machine is designed to produce air up to 150 psi, then the safety on the machine should be set for 150 psi. If with that same machine, there is an air tank designed to hold a maximum allowable working pressure ( A.S.M.E. Code Section VIII - unfired pressure vessels) of 125 psi, then the safety valves should be set at 125 psi. *The minimum design pressure of all pressure vessels is at least 30 psi, even when they are intended for use at less than 30 psi. Some vessels and machines are designed for pressures exceeding tens of thousands of psi.
