Function of the quick shut-off valve on the heat transfer oil expansion tube
Thread Content
According to the \"Specifications for Heat Transfer Oil Heating Furnace Systems\" (SY∕T 0524-2016), 8.2.2: For expansion tanks with a volume of 20 cubic meters or more, an independent rapid discharge valve should be installed; or expansion pipes should be provided in the gas phase and liquid phase areas within such tanks, with a rapid shut-off valve installed on the liquid phase pipe. What is the purpose of installing a quick shut-off valve?
The function of the quick shut-off valve is to rapidly cut off the liquid-phase pipeline in the heat transfer oil expansion tank in the event of an abnormal situation in the heat transfer oil heating furnace system, thereby reducing or preventing leaks of heat transfer oil in the system as well as safety accidents. For example, when the system experiences excessive pressure, high temperature, or other abnormal conditions, the quick shut-off valve can close immediately to prevent the heat transfer oil from leaking out of the expansion tank, thereby ensuring the safety of the work area and the personnel there. Therefore, the quick shut-off valve is a very important component in the heat transfer oil heating furnace system. -
It’s to quickly cut off the liquid phase and prevent excessive vaporization from causing an explosion, I guess? {:9001:}
