An exhaust valve should be installed at the top of the liquefied hydrocarbon sphere tank
Thread Content
Dear teachers: According to Article 6.3 of the \"Code for Safe Design of Spherical Storage Tanks for Liquefied Hydrocarbons\" (SH3136-2003), an exhaust valve should be installed on the top of spherical tanks for liquefied hydrocarbons. Is a exhaust valve referring to a manual valve? What is its function?
An exhaust valve generally refers to an automatic exhaust valve, whose function is to automatically release some gas when the pressure inside the storage tank exceeds the designed pressure, thereby preventing accidents caused by overpressure in the tank. .
