Releasable fastening structure 22, 24 is connected along the long sides 14, 16, and gathering structure 26, 28 is connected to each of the short sides 18, 20. The sheet 12 may be fabricated from Teflon material, for example.
[0017] As explained more fully below the long sides 14, 16 are releasably connected together after wrapping the flexible sheet 12 around pipe valve insulation, and the short sides 18, 20 are gathered around the pipe valve insulation by the gathering structure 26, 28.
[00181 Preferably the gathering structure 26, 28 comprises strips of elastic material secured along each of the short sides 18, 20 of the flexible sheet 12, as shown best in Figure 1. Additionally, the releasable fastening structure 22, 24 comprises Velcro fasteners with a strip of hooks 22 secured along long side 14 and a strip of loops 24 secured along long side 16. The hooks are positioned on one side of the sheet 12 and the loops are positioned on the other side.
[0019] The pipe valve insulation cover 10 of the present invention is used in combination with a pipe valve, such as gate valve 30 connected to pipe or tubing 32, as shown best in Figure 5. Valve 30 is illustrated as a simple in-line gate valve having a handle 34, but other valve configurations may also be utilized in combination with the insulation cover 10. Essentially insulation material 36 surrounds the pipe 32 while similar insulation 38 surrounds the pipe valve 30. The insulation may include a radial seam 40 to facilitate wrapping insulation 36 and 38 around the pipes 32 and valve 30.
[0020] With the pipe valve insulation 38 in place around the valve 30, the insulation cover 12 is simply wrapped around insulation 38 and secured together by the interaction between the strip of hooks 22 on long side 14 and the strip of loops 24 on the opposite long side 16. The elastic strips 26, 28 along the short sides 18, 20 gather the flexible sheet 12 of cover 10 around the insulation 36, 38, as shown best in Figure 5.
[0021] The pipe valve insulation cover 10 of the present invention functions to maintain the insulation 38 around the pipe valve 30 at all times. However, when adjustment and/or other servicing of valve 30 is required both the cover 10 and the insulation 38 are easily removed from their positions around valve 30. Upon completion of such service, the insulation 38 is simply positioned around the pipe valve, and the cover is then wrapped around the insulation, as described above. The cover tightly surrounds the insulation by way of the long sides thereof being releasably secured together by the fastening structure 22, 24 while the short sides 18, 20 gather around the insulation 38 via the elastic strips 26, 28.
[0022] Figure 6 illustrates a pipe valve insulation cover 10A releasably secured in place around a ball valve 50. Otherwise the cover 10A functions in the same manner as cover 10. Basically, the pipe valve insulation cover 10A functions to maintain the insulation 38 around the ball valve 50 until adjustment and/or other servicing of the valve is required. Then the cover 10A and the insulation 38 are easily removed from their positions around valve 50. After completion of such service, the insulation 38 is simply positioned around the pipe valve 50, and the cover is wrapped round the insulation as described above.
[00181 Preferably the gathering structure 26, 28 comprises strips of elastic material secured along each of the short sides 18, 20 of the flexible sheet 12, as shown best in Figure 1. Additionally, the releasable fastening structure 22, 24 comprises Velcro fasteners with a strip of hooks 22 secured along long side 14 and a strip of loops 24 secured along long side 16. The hooks are positioned on one side of the sheet 12 and the loops are positioned on the other side.
[0019] The pipe valve insulation cover 10 of the present invention is used in combination with a pipe valve, such as gate valve 30 connected to pipe or tubing 32, as shown best in Figure 5. Valve 30 is illustrated as a simple in-line gate valve having a handle 34, but other valve configurations may also be utilized in combination with the insulation cover 10. Essentially insulation material 36 surrounds the pipe 32 while similar insulation 38 surrounds the pipe valve 30. The insulation may include a radial seam 40 to facilitate wrapping insulation 36 and 38 around the pipes 32 and valve 30.
[0020] With the pipe valve insulation 38 in place around the valve 30, the insulation cover 12 is simply wrapped around insulation 38 and secured together by the interaction between the strip of hooks 22 on long side 14 and the strip of loops 24 on the opposite long side 16. The elastic strips 26, 28 along the short sides 18, 20 gather the flexible sheet 12 of cover 10 around the insulation 36, 38, as shown best in Figure 5.
[0021] The pipe valve insulation cover 10 of the present invention functions to maintain the insulation 38 around the pipe valve 30 at all times. However, when adjustment and/or other servicing of valve 30 is required both the cover 10 and the insulation 38 are easily removed from their positions around valve 30. Upon completion of such service, the insulation 38 is simply positioned around the pipe valve, and the cover is then wrapped around the insulation, as described above. The cover tightly surrounds the insulation by way of the long sides thereof being releasably secured together by the fastening structure 22, 24 while the short sides 18, 20 gather around the insulation 38 via the elastic strips 26, 28.
[0022] Figure 6 illustrates a pipe valve insulation cover 10A releasably secured in place around a ball valve 50. Otherwise the cover 10A functions in the same manner as cover 10. Basically, the pipe valve insulation cover 10A functions to maintain the insulation 38 around the ball valve 50 until adjustment and/or other servicing of the valve is required. Then the cover 10A and the insulation 38 are easily removed from their positions around valve 50. After completion of such service, the insulation 38 is simply positioned around the pipe valve 50, and the cover is wrapped round the insulation as described above.
