Abstract
A valve lock for securing the handle of a pipe. The valve lock includes a first housing having first and second contact points for engaging the pipe and a retention chamber that receives the handle. The first housing is in a final position to prevent rotation of the handle when the retention chamber receives the handle and the first and second contact points are seated against the pipe. A second housing has a third contact point for engaging the pipe and a lock member for disposition relative to the first housing when the first housing is in the final position and the third contact point is seated against the pipe. The lock member receives the shackle of a padlock to secure the lock member to the first housing.
Claims19
A valve lock for locking a pipe valve connected to a pipe, said pipe valve having a longitudinally extending handle rotatable relative to the longitudinal axis of the pipe, the handle being rotatable to occupy a position orthogonal to the axis of the pipe, said valve lock comprising:
- a first housing having
- i. first and second contact points for seating against the pipe;
- and
- ii. a retention chamber, said retention chamber shaped for receiving the handle,
- said first housing occupying a final position for preventing the handle from being rotated to operate the valve, said final position defined by said first housing being disposed such that (1) said retention chamber receives the handle when the handle is disposed orthogonal to the axis of the pipe, and (2) said first and second contact points are seated against the pipe;
- a second housing having
- i. a third contact point for seating against the pipe;
- and
- ii. a lock member for disposition relative to said first housing when (1) said first housing is in said final position and (2) said third contact point is seated against the pipe,
- and wherein said lock member having a structure for cooperating with the shackle of a padlock for securing said lock member to said first housing.
A valve lock for locking a pipe valve connected to a pipe, said pipe valve having a longitudinally extending handle relative to the longitudinal axis of the pipe, the handle being rotatable to occupy a position orthogonal or parallel to the axis of the pipe, said valve lock comprising:
- a first housing having
- i. securing legs for seating against the pipe, and
- ii. a retention chamber, said retention chamber shaped for receiving the handle,
- said first housing occupying a final position for preventing the handle from being rotated to operate the valve, said final position defined by said first housing being disposed such that (1) said retention chamber receives the handle, and (2) said securing legs are seated against the pipe;
- a second housing having
- i. at least one securing leg for seating against the pipe;
- and
- ii. a lock member for disposition relative to said first housing when (1) said first housing is in said final position and (2) said securing leg of said second housing is seated against the pipe,
- and wherein said lock member having a structure for cooperating with the shackle of a padlock for securing said lock member to said first housing.
