The invention relates to a pot cover and a pressure cooking utensil and relates to the technical field of cooking utensils. According to the main technical scheme, the pot cover is used for the cooking utensil and comprises an upper cover, a screw cap and a limiting mechanism, wherein the screw cap is arranged on the upper cover and is used for being fastened to a pot body of the cooking utensil in a rotating manner; the limiting mechanism limits the screw cap on the upper cover, and thus the screw cap cannot rotate relative to the upper cover; when the pot cover is fastened to the pot body of the cooking utensil, the screw cap is rotated, and the cooking utensil is located in a covered state; and after the cooking utensil is opened, the limiting mechanism limits the screw cap. The pressure cooking utensil comprises the pot cover. The pot cover is manly used for limiting the screw cap on the pot cover on the upper cover and preventing the screw cap from rotating relative to the upper cover after the pressure cooking utensil is opened, so that the phenomena of interference and collision of the screw cap and the pot body when the pressure cooking utensil is covered are avoided, and the pressure cooking utensil can be smoothly covered.
