The utility model relates to the technical field of oil fields, in particular to a fracturing wellhead device with a heating and deicing valve, and solves the problems that when media (water and the like) of a wellhead device in the prior art are subjected to ice blockage during blowout and the like (water and the like in a valve cavity are frozen at low temperature, and pressure control pieces in the valve cavity, such as a flashboard, a valve body and a valve seat, are blocked by ice blocks), the valve cannot be opened and closed, and the pressure control pieces cannot be opened and closed. And when a wellhead device is pressed, safety accidents of equipment, personnel, environment and the like are easy to occur, and the production is also seriously influenced. A fracturing wellhead device with a heating deicing valve comprises a valve body, a plurality of connecting grooves are formed in the top of the valve body in the circumferential direction of the valve body, a heater is arranged in each connecting gr
