I would appreciate help from all experts: Should an emergency automatic shut-off valve be installed at the bottom of liquid ammonia storage tanks? This post was last edited by hw197358 on 2009-2-19 at 19:44.]
Typically, liquid ammonia spheres are equipped with a high liquid level alarm interlock system; when the liquid level in the sphere reaches the set high-level threshold, the valve at the base of the sphere shuts off automatically to prevent the liquid level from rising too high.
Liquid ammonia spherical tanks must be equipped with high and low liquid level alarm interlocks.
Emergency automatic shut-off valves should be installed at the liquid ammonia tank for its inlet and outlet pipelines, in order to ensure the safety of the tank. These valves serve as a means to isolate the tank promptly in case of emergencies such as leaks in the inlet or outlet pipelines.
It should be provided, just like with liquefied gas, with a pneumatic valve or spindle oil drive:)
An automatic shut-off valve should be installed at the bottom of the tank. Its main functions are as follows: 1. When the flow rate in the filling pipeline is too high, it shuts off the pipeline promptly to prevent a large amount of liquid ammonia from leaking. 2. In emergency situations, the pipeline can be shut off remotely to prevent accidents.
Definitely, definitely – cut off the flow when there are leaks in the outlet pipelines and pump body, to minimize leakage and thus reduce the risk of accidents； In case of special circumstances, perform an emergency shutdown to ensure the safety of lives and property.
It should be set up. Fourth floor, what was said about the seventh floor is correct
Our facility started operations last year, and the design drawings did not include this feature. I would like to ask everyone here what the basis is for installing automatic shut-off valves?
It is primarily designed to provide automatic protection in various emergency situations: for instance, when pipeline ruptures and severe leaks occur due to factors such as the movement of tank trucks, collisions, explosions, earthquakes, or issues with the quality of welding and fittings. This is a very important safety measure, but unfortunately many organizations do not have it.
I would like to ask the experts: what is the basis for setting up automatic shut-off valves?
Which type of emergency shut-off valve is used most often? Hydraulic control, pneumatic, or electric?
Dear engineers, our plant also has two 5000m3 spherical tanks; it only has alarms for high and low liquid levels, but no interlocks. There’s no such thing as an emergency automatic shut-off valve as you mentioned, so do we have to rely on our own efforts to eliminate these potential hazards? Are there any experiences?
