How to replace a Hot Water Boiler Relief Valve?
I have a hot water oil burner. I need step by instructions on how to replace the pressure relief valve.
Do you know?
Please help me.
Your first question should be why did my releif valve fail! is the expansion tank waterlogged or low on air pressure, is the water fill valve allowing the system to overpressure, is the aquastat failing or improperly adjusted....You need to figgure out what made it fail before you throw money into a new valve.
beyond that the other guy said it fairly well, personally i would isolate the boiler if there are valves on the supply and return, release the pressure AFTER killing the power to the boiler and letting it cool off, knock the pressure off the boiler, spin the valve off, dope the threads and reinstall...not hard...remember righty tighty lefty loosey
Safety valves and relief valves and differences between the definition of
Safety valve is a boiler, pressure vessels and other pressure equipment subject to important safety accessories. Reliability and performance of its action is directly connected to the equipment and personal security, and closely related with the energy saving and environmental protection. However, some users and design departments in the selection, always choose the wrong model. This paper to analyze the selection of the safety valve.
Defined Broad sense, including the so-called safety valve relief valve, from the rules point of view, directly installed in the steam boiler or pressure vessel on a class, the necessary condition that must be approved valve technology supervision department, the narrow the known safety valve, relief valve for other general call. Safety valves and relief valves in the structure and performance is very similar, both are more than open automatically when the discharge pressure of the internal medium, to ensure plant safety. By the existence of such a nature similar to the dry nature, people, when used, often confuse the two, In addition, some production equipment used in the rules which can be also provided. Therefore, the difference between the two is often overlooked. So also there were many problems between. If you want to make a more precise definition of the two, may be in accordance with the "ASME Boiler and Pressure Vessel Code," first articulated in the definition to understand:
(L) safety valve (SafetyValve) a kind of static pressure from the valve before the media-driven automatic pressure relief device. It is characterized by a sudden opening of the wide open action. The occasion for the gas or vapor.
(2) relief valve (ReliefValve), also known as a kind of relief valve static pressure from the valve before the media-driven automatic pressure relief device. It opened with the pressure exceeds the growth of power in proportion to open. Mainly used for fluid situations.
(3) safety relief valve (Safet ReliefValve), also known as a kind of safety relief valve pressure driven by the media automatic pressure relief device. Use different according to both valid for the safety valve is also valid for the relief valve. Japan, for example, safety valves and relief valves to make a less clearly defined, usually large-scale energy storage such as a boiler pressure vessel safety device called the safety valve, installed in the pipeline or other facilities of the said set of the bleed valve. But under MITI's "thermal technology" provision of view, the device an important part of security, specify the use of safety valves, such as the boiler, superheater, reheater and so on. In the valve of the lower side with the boilers and turbines need to phase, where you need to install a relief valve or safety valve. This view, the safety valve required more reliable than the relief valve. In addition, from the Japanese Ministry of Labour's high-pressure gas management rules, the Ministry of Transport and Shipping Association's rules at all levels, the identification of safety and emissions regulations, we put the call to ensure the safety valve emissions, but not guaranteed emissions valve called the relief valve. Kai in the country regardless of type or Weiqi all collectively referred to as safety valve.
