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 Difference between relief valve and safety valve?
Relief valve always position in the suction line in oreder to relief the extra pressure, while safety valve is always placed at discharge line to release excess pressure.I would take that one step further by stating that a " RELIEF VALVE" is one that is "meant" to be lifted off its seat, as opposed to a "SAFETY RELIEF VALVE" which is not!DIFFERENCE BETWEEN RELIEF VALVE AND SAFETY VALVE:1. Releif valve is applicable in the fluid system.safety valve is applicable in the gaseous system.2.Relief valve opening is directly proportional to the pressure rise.Safety valve opening is will happen at after reaching the setpressure.3.Mode of relif vlave line is again connected to the suction.But in the safety valve is just vent-out there is no connection tosuction.
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.
Why is a throttling valve called an expansion valve?
It is not.. A globe , needle , ball valve are used for throttling For expansion either a shock absorber , diaphragm tank or air chamber are used to allow for expansion
What is mean by cold chamber die casting machine?
cold chamber die casting machine can be divided into the direction of the direction of the flow of fluid in the hydraulic system used to control or regulate the pressure and flow valves, pressure valves and flow control valve three categories. A same shape as the valve, because of the different mechanisms of action have different functions. Pressure valve and flow valve with a throttle effect of the flow passage cross section to control the system pressure and flow direction valve replacement of the flow passage control the oil flow direction.
What is a huddling chamber on a safety valve?
A huddling chamber on a safety valve is a specific design feature that enhances the performance of the valve, particularly in terms of ensuring reliable and consistent operation under certain conditions. Here’s a more detailed explanation: Purpose of a Huddling Chamber Enhancement of Lift Force: The huddling chamber is designed to increase the lift force applied to the safety valve disc once the valve begins to open. This helps ensure that the valve opens fully and quickly when the set pressure is reached, allowing for the rapid release of excess pressure. Improved Blowdown Control: The huddling chamber helps in controlling the blowdown, which is the difference between the pressure at which the valve opens (set pressure) and the pressure at which it closes (reseat pressure). Proper blowdown control is essential to prevent the valve from chattering (rapid opening and closing) and to ensure that it reseats properly without excessive loss of the process medium. Common examples of safety valves with huddling chambers can be found in various industrial applications where controlling pressure is critical. Here are a few specific examples: Steam Boilers: Application: Safety valves in steam boilers prevent overpressure, which can lead to explosions. Example: A huddling chamber in the safety valve of an industrial steam boiler ensures that the valve opens rapidly and fully at the set pressure, releasing steam quickly to bring the pressure down. Pressure Vessels: Application: Pressure vessels store gases or liquids under pressure, such as in chemical plants or refineries. Example: Safety valves with huddling chambers are used to release excess pressure safely, preventing vessel rupture. Petrochemical Plants: Application: In petrochemical processing, maintaining precise pressure control is essential for both safety and product quality. Example: Huddling chamber-equipped safety valves help manage sudden pressure spikes in reactors and storage tanks.
What are the safety of boiler safety valve?

In the heart the valve between the right lower chamber and its vessel is what valve?
The valve between the right lower chamber of the heart (right ventricle) and its vessel (pulmonary trunk) is the pulminary semilunar valve.
When was Huddling Place created?
Huddling Place was created in 1944.
What will you find on a pressure cooker a safety pin b safety jacket c safety valve?
safety valve
What is different between pressure safety valve and temperature safety valve?
Pressure safety valve-are the valve who are designed such that it can control the pressure , like in the water blowers etc,and Temperature safety valve are those who are used to regulate the temperature like, in water boilers.
How does huddling help penguins to stay warm?
by huddling they sharing their body heat
What is the intake and exhaust valve purpous?
The fuel/air mixture passes through the intake valve to get into the combustion chamber. After combustion, the spent gasses travel out of the combustion chamber through the exhaust valve.
What is the function of an intake valve?
The intake valve opens to allow the fresh charge of air and fuel into the combustion chamber then closes to seal the chamber during compression.
Where is the carburetor needle valve?
It is in the float chamber of the carburetor.
