The system provides a valve closing mechanism comprising a control panel, a number of air driven motors, a corresponding number of air lubricators and drive shafts.
Powered cylinder opening is not provided by the ChlorGuard system for safety reasons. The drive shaft transmits the torque and rotation from the drive air motor to the cylinder valve. Each shaft is specifically designed to match one particular valve type. The ChlorGuard drive assembly can be easily connected to and disconnected from the cylinder. When ChlorGuard has been removed there is easy access for manual re-opening of the valve.
The unit is operated by air which is supplied under pressure from a compressor or receiver system. The system provides a constant, predetermined pressure to drive the valve closed.
Operation of the mechanism to close the valve may be triggered automatically by the chlorine in air sensor within the enclosure housing the cylinder, and/or it may be initiated manually by means of a user operable press button located remotely from the storage vessels. A further closing actuation can be achieved manually from the control panel.
. . . either by an operative (who will press the button), and/or by the detector, the system operates to close the cylinder valves. The high pressure storage system is designed and arranged so that there is sufficient pressure available at all times to operate and effect complete closure of all of the cylinder valves.
