What is a tricock valve?
It is a small, valve usually used to manually check if water is above the valve connection on a boiler or tank. There may be several of them at different heights on the boiler or tank. There is a handwheel on the valve, an inlet connection (which is attached to the boiler) and an outlet (usually left unconnected). When filling the boiler or tank, the try-cocks can be left open. Water coming from the try-cock means the tank is filled to at least that level. The valve is then closed.
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.
What is the Use of Balance leak off line in Boiler feed pump?
avoid thrust
How does marine boiler safety valves easing gear works?
assalamualaikum & peace be upon u all what i know is that a safety v\v easing gear is used to operate the safety valve manually, so when u lift up the easing gear handle it will press the spring surrounding the v\v spindle causing the valve to be opened up and allowing excess steam to be released so boiler pressure dropes..tq
What is meant by marcet boiler?
the apparatus ( Marcet Boiler ) consist a cylinder surrounded with isolated substance in it electrically heated boiler which is used to heat up water and to measure the both of the temperature and pressure, & it contains thermometer & barometer & safety valve .
What is the feed check valve of boiler?
The feed check valve of a boiler is on the line coming out of the boiler it is usually to prevent the water from going back in to the boiler its coming out of so it would build up excessive amounts of pressure which will cause the t&p valve to blow temperature and pressure
In boiler feed water line whether a non return valve should precede or succeed the delivery valve of feed water pump?
In boiler feed water line the NRV is normally installed between Pump and stop valve if the line is short and an another NRV is installed at boiler entrance and after stop valve if the line is long or pump is 10 to 15 m away from the boiler.
What is digester feed pump?
A digester feed pump forces water to a boiler. It works by transferring cool water to the boiler to be heated.
What is the function of back pressure valve in Boiler feed pump?
The function of back pressure valve is to prevent back flow to the pump in case there is an obstruction on downstream side of valve.
Why two safety valve provide to boiler?
standby valve,
What is boiler feed water pump?
Boiler feed pumps are an important part of any boiler operation. They control the amount of water fed to the boiler and the manner in which it is fed.
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.
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.
What is the PH value in boiler feed water?
the pH value in boiler feed water is 9.2
What is the application of boiler stop valve?
Stop Boiler Valve (or Crown Valve) is installed on an outlet line of a boiler. It's purpose is isolation of a boiler from a downstream steam line. Its position may be either open or close, it cannot be used for throttling of steam.
What is boiler feed water?
Boiler feed is the fresh or treated water to replenish the water loss though evaporation or leak
What are the safety of boiler safety valve?
