An insulating material protective cover for a valve unit for protecting insulating materials provided so as to cover the valve unit for insulation of the valve unit, the valve unit including a valve body connected between at least two pipes, a shaft protruding from the top of the valve body, and a wheel coupled to the upper end portion of the shaft so as to be rotatable to open and close a valve, the protective cover comprising:
- a first split body including a first plate having a curved surface corresponding to a curved surface of a lower portion of the valve unit or the valve body and having a length corresponding to a length of the valve unit, first finishing chassis coupled to both end portions of the first plate in the widthwise direction, respectively, and second plates coupled to both end portions of the first plate in the lengthwise direction, respectively, so as to be perpendicular to the first plate;
- a second split body including a third plate having a shape corresponding to one side surface of an upper portion of the valve unit or the valve body and having a length corresponding to a length of the valve unit, second finishing chassis coupled to both end portions of the third plate in the widthwise direction, and fourth plates coupled to both end portions of the third plate in the lengthwise direction, respectively, so as to be perpendicular to the third plate;
- a third split body including a fifth plate having a shape corresponding to the other side surface of the upper portion of the valve unit or the valve body and having a length corresponding to the length of the valve unit, a second finishing chassis coupled to a first end portion of the fifth plate in the widthwise direction to be brought into contact with the first split body, and a first finishing chassis coupled to a second end portion of the fifth plate in the widthwise direction to be brought into contact with the second split body, and sixth plates coupled to both end portions of the fifth plate in the lengthwise direction so as to be perpendicular to the fifth plate,
- wherein the protective cover is configured by assembling the first to third split bodies so as to cover valve unit and be separable,
- each of the first finishing chassis of the first split body and the first finishing chassis of the third split body has a first coupling portion having a U-like cross-section shape having a first insertion groove for inserting an end portion of the first plate or the fifth plate such that the first finishing chassis can be coupled with the first plate or the fifth plate by pressing the first coupling portion, and a first supporting part formed so as to extend from an end portion of the first coupling portion in a direction perpendicular to the first coupling portion, and having an L-like cross-section shape as a whole, and
- each of the second finishing chassis of the second split body and the second finishing chassis of the third split body has a second coupling portion having a U-like cross-section shape having a second insertion groove for inserting an end portion of the third plate or the fifth plate such that the first finishing chassis can be coupled with the third plate or the fifth plate by pressing the first coupling portion, an extension portion formed so as to extend from an end portion of the second coupling portion to the opposite side to the second coupling portion, and a second supporting portion formed so as to extend in a vertical direction from a portion of the second coupling portion and be perpendicular to the second coupling portion and the extension portion, and having a T-like cross-section shape as a whole.
