Abstract
An insulation jacket for use as a valve cover. The jacket comprises a body portion comprising a central section and two lateral sections. Each of the lateral sections comprises an inboard and outboard belt and each of the belts extends along each of the lateral sections. The ends of each of the belts is adapted to interlock whereby the insulation jacket may be securely fastened around a valve casting.
Claims11
A three-piece thermal insulation jacket for use as a valve cover, said jacket comprising:
- (a) a body portion comprising a central section and two lateral sections each lateral section including an inboard and outboard belt, each lateral section having two ends and a flap at each end, the flaps at each end of the jacket being separated by a U-shaped cutout at each end of said central section, each of said belts extending along each of said lateral sections, the ends of each of said belts being adapted to interlock with each other said body portion adapted to be disposed around a horizontal section of a valve casing, said U-shaped cutouts adapted to be disposed around an upstanding section of said valve casing, whereby said body portion may be securely fastened around said valve casing;
- (b) a skirt section, comprising two parabolic sections adapted to cooperate with each of said U-shaped cutouts whereby said skirt is adapted to surround said upstanding section;
- and
- (c) an insulation cap having a upper wall and a lateral wall, said lateral wall adapted to surround said skirt, whereby said body portion, said skirt and said cap assure an essentially complete seal when they are positioned about said valve casing.
A thermal insulation jacket for use as a valve cover, said jacket comprising:
- a body portion comprising a central section and two lateral sections each comprising an inboard and outboard belt, each of said belts extending along each of said lateral sections, the ends of each of said belts being adapted to interlock with each other whereby said insulation jacket may be securely fastened around a valve casing, each of said lateral sections having two ends and a flap at each end of said section, the flaps at each end of said jacket separated from one another by a U-shaped cutout adapted to surround the base of said valve casing, said body portion including insalation padding and each of said lateral sections including insulation padding, only one flap on each of said lateral sections including insulation padding, the other of said flaps including no insulation padding.
A thermal insulation jacket used to cover a valve casing which has an upstanding section and a horizontal section, said horizontal section including a flange at each end adapted to be connected to a pipe, said jacket comprising:
- a body portion having a central section and two lateral sections, each lateral section including an inboard and an outboard belt, each of said belts extending along each of said lateral sections, the ends of each of said belts being adapted to interlock with each other, whereby when said jacket is wrapped about said horizontal section of said casing, each of said inboard belts surrounds one of said casing flanges and each of said outboard belts extends beyond a respective one of said flanges and around said pipe whereby said insulation jacket is securely and tightly fastened around said valve casing and is tightly sealed about said horizontal section.
