Abstract
An apparatus for purging a water supply line during winter weather conditions using pressurized air includes an air tank capable of holding a sufficient supply of pressurized air to purge the supply line. A valve is connected to an air port of the tank and has a valve member movable between open and closed positions to control the flow of air into and out of the air tank. There is an air bleeder mechanism having an air inlet connectible to the supply line and an air outlet. The mechanism permits air, but not water, to pass from the supply line to the air tank and also permits air to flow back through the mechanism into the supply line. A manually operated valve is used to permit atmospheric air to flow through the air bleeder mechanism to the supply line.
Claims20
A water supply system for use with a pump and suitable for winter weather conditions comprising:
- a water supply line connectible to a pump;
- a line connector with first and second water outlets and a water inlet, the latter connectible to said supply line;
- a one-way check valve operably connected to said first outlet and connectible to a pressure tank for supplying water, said check valve permitting water to flow in one direction only into said pressure tank;
- an air tank capable of holding a supply of air under pressure and having an air inlet;
- and
- line and valve means connecting said air tank to said line connector, said line and valve means including an air bleeder valve arrangement for permitting air to escape from said supply line upon operation of said pump and for permitting air back into said line when said pump shuts off and a further valve arranged between said air bleeder valve arrangement and said air inlet and movable between an open position in which air can flow into or out of said air tank and a closed position in which pressurized air is unable to flow out of said air tank;
- wherein said air bleeder valve arrangement has an open position where air from said supply line can escape to atmosphere upon operation of said pump and a closed position in which air from said supply line can pass into said air tank and pressurize same upon operation of said pump.
An apparatus for purging a water supply line during winter weather conditions, said apparatus including:
- a water line connector having first and second outlets and an inlet connectible to a water supply line, said first outlet being connectible to a water tank for supplying water under pressure;
- an air bleeder mechanism connected to said second outlet for permitting air to escape from said supply line upon operation of a water pump connected thereto and for permitting air back into said line, when said pump shuts off;
- an air tank capable of holding a supply of air under pressure and having an air port;
- and
- valve means for operatively connecting said air bleeder mechanism to said air port of the air tank, said valve means including a valve member movable between an open position in which air can flow either into said air tank from said air bleeder mechanism or out of said air tank to said air bleeder mechanism and a closed position in which pressurized air is unable to flow out of said air tank.
An air tank device for purging a water supply line during winter weather conditions using pressurized air, said device comprising:
- an air tank capable of holding a sufficient supply of pressurized air to purge a water supply line with said pressurized air, said tank having an air port;
- a valve connected to said air port and having a valve member movable between an open position in which air is free to flow into or out of said air tank and a closed position in which pressurized air is unable to flow out of said air tank;
- an air bleeder mechanism having an air inlet connectible to said water supply line and an air outlet, said bleeder mechanism permitting air, but not water, to pass from said supply line, through said air bleeder mechanism and to said air tank, and permitting air to flow back through said air bleeder mechanism into said water supply line to facilitate draining and purging said water supply line;
- and
- means for selectively permitting atmospheric air to flow through said air bleeder mechanism to said water supply line.
An air tank device for purging a water supply line during winter weather conditions using pressurized air, said device comprising:
- an air tank capable of holding a supply of pressurized air to purge a water supply line with said pressurized air, said tank having an air port,
- air compressor means connectible to said air tank to provide pressurized air to said air tank when required;
- an air bleeder mechanism having an air inlet connectible to said water supply line and an air outlet, said bleeder mechanism permitting air, but not water, to pass from said supply line, through said air bleeder mechanism and to said air tank, and permitting air to flow back through said air bleeder mechanism into said supply line to permit draining and purging said water supply line;
- and
- means for selectively permitting exterior air into said device.
