Should a safety valve be installed?
Thread Content
In our company, the hydrochloric acid and liquid caustic storage tanks used for producing purified water have the raw materials prepared under vacuum; after adding water to achieve the desired concentration, compressed air is used to push the solution into the anion and cation exchange beds. I wonder whether safety valves are installed on these storage tanks But there is no space available, and there is a risk that the glass mirrors might break under pressure, leading to safety accidents. What should be done in such a situation?
It is better not to install a safety valve, to avoid adding more leakage points. Glass mirrors that are properly designed and manufactured should be reliable.
As long as the pressure inside the equipment does not automatically exceed the limit, it can be installed on the intake pipeline; in other words, the design pressure of the equipment is already equal to or higher than the pressure from the pressure source.
I’m not sure whether it’s possible to install a safety valve on the pipeline as mentioned above. Also, should the size of the safety valve be determined based on the flow rate of the pipeline? It can’t just be chosen arbitrarily; rather, it should depend on the opening condition of the pipeline valves.
A safety valve can be installed on the intake pipeline; for specific requirements, it is recommended to refer to GB50316 \"Code for Design of Industrial Metal Piping\", and a full-opening safety valve should be used. For reference!
It is possible to consider installing safety valves on the pipeline. It is generally difficult to install safety valves on storage tanks; instead, breather valves are used to connect them to the system. A buffer tank can be installed based on the conditions on site, and a safety valve can be connected to the system to control its pressure.
A safety valve is installed in the system, that is, on the intake pipeline
It is possible to consider installing a safety valve on the intake pipeline; in accordance with GB50316 \"Code for Design of Industrial Metal Piping\", a full-open type safety valve should be selected.
Safety valves are not required on storage tanks, but they are essential for the system. Safety valves can be installed on pipelines in accordance with GB50316 \"Code for Design of Industrial Metal Piping\".
If no safety valve is installed on the equipment, safety valves are generally installed on the pipes as part of the standard process.
Safety valves are generally not installed on the tank; they can be placed on the tank’s outlet pipeline instead.
Yes, if it’s to be installed, it should be installed on the pipeline. But why use compressed air when adding acid or base solutions to the yin-yang bed? Isn’t it better to use an acid-base sprayer?
