| description | The invention relates to the technical field of valves, in particular to a valve with a stepped temperature-limiting and pressure-limiting sealing structure, which comprises a valve body, a valve rod arranged in the valve body and a first spring arranged on the valve rod in a sleeving manner; the valve cover is located above the valve body and connected with the valve body in a sealed mode, a driving piece connected with the valve rod is arranged in the valve cover, the driving piece rotates to drive the valve rod to move up and down, and abutting sealing faces are formed between the driving piece and the valve cover through pushing of the first spring and pushing force of the valve element and the valve seat to the driving piece. A throttling channel is arranged between the driving piece and the valve cover, and a first sealing ring is arranged above the driving piece to form stepped temperature-limiting and pressure-limiting sealing; the valve bonnet is located above the valve cover and is in sealing connec |
