Is the standard schematic diagram of hotel gas stove and natural gas interface the same?

Same. Gas stove interfaces are mostly embedded gas stoves, and the gas used is mostly natural gas. Some gas stove manufacturers will also consider the user's gas connection when designing the gas stove interface, and adopt interfaces that are compatible with threaded connection and parallel connection. The plug-in connection mode of rubber hose can be directly used; Alternatively, the rotatable gas connector at the gas inlet of the gas stove can be removed and connected with a metal threaded pipe.
