The difference between household gas pipeline valves and heating pipeline valves: household gas pipeline valves generally use soft seal (such as rubber) valves, or use corrosion-resistant and sulfur-resistant material pipeline valves, because the natural gas transported by the pipeline contains a large amount of hydrogen sulfide before desulfurization (This is a poisonous and highly corrosive gas). Household heating pipeline valves generally use temperature control valves or copper ball valves, and shut-off valves are generally used on pipelines. There are also locking regulating valves, filters, heat meters and balance valves at the entrance.
