Abstract: An insulation device for a low-temperature pipe according to the present disclosure includes: a pair of primary insulation materials surrounding a first radially outer surface and a second radially outer surface of the pipe; a pair of secondary insulation materials surrounding outer surfaces of the primary insulation materials; a pair of tertiary insulation materials surrounding outer surfaces of the secondary insulation materials; a pair of finishing covers surrounding outer surfaces of the tertiary insulation materials; an out-profile coupled to each of the finishing covers so as to surround each of widthwise opposite ends of the finishing cover; and an in-profile coupled to each of the finishing covers so as to surround each of lengthwise opposite ends of the finishing cover, wherein the pair of secondary insulation materials are configured such that each of opposed contact surfaces thereof is formed in a shape bent at least one time.

Abstract: The present invention relates to an insulating material protective cover for a valve unit. The insulating material protective cover for a valve unit, according to the present invention, comprises: a first split body including a first plate, first finishing chassis respectively coupled to both end portions of the first plate in the widthwise direction, and second plates perpendicular to the first plate and respectively coupled thereto; a second split body including a third plate, second finishing chassis respectively coupled to both end portions of the third plate in the widthwise direction, and fourth plates perpendicular to the third plate and respectively coupled thereto; and a third split body including a fifth plate, a second finishing chassis coupled to a first end portion of the fifth plate in the widthwise direction, a first finishing chassis coupled to a second end portion of the fifth plate in the widthwise direction, and a sixth plate perpendicular to the fifth plate and coupled thereto.

Abstract: In a pipe insulation apparatus includes a plurality of segments which are connected so as to be separable along division lines, and each of the plurality of segments is composed of a plurality of insulation layers, and is covered by a finishing cover. The finishing cover includes: at least one joint chassis that is made of a soft metal material, and has a first insertion groove and a second insertion groove formed at a first end portion and a second end portion, respectively, and has a saw-toothed first protrusion formed on one inner side surface of each of the first insertion groove and the second insertion groove and a saw-toothed second protrusion formed alternately with the first protrusion on the other inner side surface; and a plurality of plates that is made of a soft metal material.

Abstract: Juice extractor, is disclosed, for crushing fruits or leaves, or root of green vegetable for extracting green juice, wherein, considering the incomplete juice extraction of the related art juice extractor, the present invention is provided with thread end portions and vacant portions at a rear portion of a screw for enhancing a crushing effect, and a fore end portion with reduced diameter at a fore end thereof, to which fore end a juice extracting member having detachable extracting net member and mounting member is coupled for secondary extraction, that improves a juice extraction efficiency, whereby further improving a pressing effect of the raw material for extracting juice, which provides a better yield, allowing an easy removal of remnants accumulated inside of the juice extracting components, to maintain the extractor clean, reducing a ratio of elasticity degradation caused by a prolonged use, and using in making noodle, as an alternative use.
