Abstract
There is disclosed a flushing device for flushing water from conduits in a house, trailer or the like by using the device to connect water conduits to a source of pressurized air for removing or discharging water from the conduits when required.
Description
21~2140 -TECHNICAL FIELD OF INVENTION
This invention relates to a device for flushing water from conduits located in a house, trailer or the like.
More particularly, this invention relates to a device by which water conduits may be connected to a source of pressurized air for removing or discharging water from the conduits when required.
BACKGROUND OF THE INVENTION
In climates where water conduits in houses or trailers are exposed to temperatures which could cause rupture to the conduits during periods of freezing weather, it is necessary to take protective steps to prevent damage occurring. By way of example, trailers used as recreational vehicles, summer cottages or the like must have the water systems drained before being stored or closed for the winter season. In the alternative, water conduits may be provided with thermal protection, or alternately, may be provided with anti-freeze solutions to prevent damage. The use of thermal protection can be relatively expensive while for environmental reasons, anti-freeze compositions such as glycol based compositions are not desirably introduced into the environment per se.
The prior art also includes devices to permit air to enter conduit system such as that shown in Canadian Patent No. 29,031 but such devices as disclosed in this reference do not permit introduction of air under pressure. Devices such as aerosol valves are well-known for use in aerosol applications but in their field of use do not structurally provide a device capable of direct and quick connection to a water conduit having eg. a threaded connection.
Conventionally, however, it is more desirable to drain the conduits if possible but for many reasons including improper conduit installation, lack of appropriate access to any low points of drainage for a system, it is not always possible to fully drain a system, which can result in broken pipes, etc.
SUMMARY OF THE INVENTION
The present invention provides a flushing device adapted to be connected to the water conduit system to be drained --in buildings, houses or the like which require protection for the water system to prevent damage due to freezing.
More particularly, in one embodiment of the present invention, there is provided a flushing device suitable for draining water from a home, trailer or the like in which there is one or more water conduits which would be subject to damage upon freezing, said flushing device comprising in combination an air inlet valve, means for determining a pressure load applied to a conduit, means for releasably coupling said air inlet valve to said conduit, means for operatively connecting said air inlet valve to said means for determining said pressure load.
In another embodiment, there is a provided a device similar to the above but in which the device may be coupled to a water conduit system without the necessity of employing lS pressure determining means; this embodiment comprises in combination an air inlet valve and means for releasably coupling said inlet valve to said conduit.
In yet another embodiment, there is provided a device similar to the above; this embodiment comprises in combination an air inlet valve, an air release valve and means for releasably coupling said inlet valve to said conduit.
In a still further embodiment, there is provided a device similar to the above; this embodiment comprises in a quick release connector for connecting said conduit to one or more of said air inlet valve, said air release valve or said pressure gauge assembly or alternatively, directly to a source of pressurized air.
- The present invention operates on the principle of permitting the water in water conduits to be removed by applying a source of pressurized gas such as atmospheric air to the conduit system to displace the water from the conduit system.
In practising the present invention, normally the water will be permitted to drain from the system by opening appropriate discharge points in the system (eg. taps, drain plugs or the like), following which the flushing device will be applied to the conduit system and a source of pressurized air passed through the conduits to remove any residual water which may be trapped in conduit elbows, drain taps or the like. Typically, and by way of example, many recreational vehicles, summer homes or the like include a conduit extending exteriorally of the vehicle or residence. Normally such outdoor conduits include a threaded male or female connection for coupling to eg. a hose. The device of the present invention may be coupled directly to the exterior threaded connection and from the exterior of the house or vehicle, a source of pressurized air can be injected in the water system.
By appropriate opening and closing of interior taps or the like, the source of pressurized air will create a flushing action of the conduit system to remove residual water from the conduit system. In the embodiment where pressure gauge means are employed in the device of the present invention, supply of pressurized air to the system can be determined to a desired pressure level, and at the same time, when the pressure of the pressurized air falls to low level, a user will be able to ascertain that the particular conduit has been successfully cleared of most, if not all, water.
In accordance with this invention, the device is preferably a one-piece flushing device with all of the parts integral with one another. To this end, the unit may be manufactured from appropriate materials ranging from metal or plastic housings which are provided with a valve component integrally associated therewith, preferably either on an in-line basis or by means of an associated mounting member mounting the valve to a main housing which connects the pressure measuring means and the coupling means.
In turn, the individual components forming the integral unit can have appropriate conventional structures; for example, the valve component is preferably a one way valve which may have a threaded surface for receiving a protective covering or for threadably connecting to an air source. The valve component can be any suitable simple structure such as valves typically used in pneumatic tires for automobiles or bicycles. When the device is not in use, a threaded cap may be threaded onto the valve.
21321~0 The valve is associated with the coupling by having a continuous passageway extending between the valve inlet and the coupling means for coupling the device to a conduit system. In one embodiment, the valve may be mounted on an in-line basis directly with the passageway of the coupling; the passageway between the valve and the coupling can be of a relatively narrow diameter since large volumes of pressurized air will readily pass through a narrow passageway.
The coupling member may be a suitable coupling assembly, preferably threaded to matingly engage with a threaded tap member of a conduit system. Such coupling members can be similar to hose connections which are used to couple hose lengths to suitably threaded taps. In other cases, one may employ suitable conventional quick connect couplings which may engage with threaded or non-threaded terminals of conduits. Desirably, suitable sealing washers are employed with the coupling means to ensure a pressure tight fit with the terminals of the conduits.
In the embodiment where a pressure gauge is employed with the device of the present invention, a central housing or hollow body may be employed which individually mounts the valve means, the pressure gauge means and the coupling means in fluid tight contact with each other. As in the above arrangement, fluid communication between the valve means and the pressure gauge means may be achieved by mounting the valve means between the pressure gauge means and the coupling means.
Any suitable pressure gauge means may be employed such as digital pressure gauges, analog gauges or the like.
The device of the present invention is simple to manufacture and easy to use. It is particularly adapted for use in situations where a source of pressurized air supplied by a conventional compressor, or a portable compressor, may be employed to provide the source of pressurized air to be injected into the system. The device may be used on a seasonal basis or in other cases, may be used to also check for the pressure integrity of the water conduit system to determine the presence of any leaks.

DETATr~n DESCRIPTION ACCORDING TO THE
PREFERRED EMBODIMENTS OF THE PRESENT INVENTION
Referring now to the drawings and in particular Figures 2 and 3, an example of the apparatus according to the present invention is shown which includes a one-way air valve 1 with a threaded valve stem 2 for connecting the valve to an air source and an actuator means 3 designed to open the valve when air is being pumped through it.
The apparatus also includes, in the embodiment illustrated in Figures 2 and 3, a conduit body 4 formed with an internal fluid passage 12. Mounted on the conduit body 4 is a valve 1, a gauge assembly 5 and a coupling ring 6 which is threaded internally at 7 and used in conjunction with a washer 21~2140 8. The size of the ring with its threading is designed to be threaded directly to a standard outlet/inlet of a water conduit 9-as shown in Figure 1.
As an option, the end of the said valve stem indicated by 21 may be threadably connected to said conduit body and another option is to cast the said valve and conduit body as one piece.
The flushing device illustrated in Figures 2 and 3 is used as follows. The ring 6 is tightly threaded into position on the standard outlet/inlet of water conduit 9 with the valve of the outlet/inlet turned to the off position. The water source of the water conduit system is shut off and the outlet at the lowest possible point of the system is opened. An air source is then connected to the valve stem 2, the actuator means 3 is depressed and air is pumped into the water conduit. The water displaced by the pumped air entering the conduit is expelled from the water conduit through the open outlet.
The gauge assembly 5 in this device is used to check for leaks in a water conduit system and is used as follows. The ring 6 is tightly threaded into position on the st~n~rd outlet/inlet of water conduit 9 with the valve of the outlet/inlet turned to the off position. The water source of the water conduit system is shut off and all outlets of the system are closed. An air source is then connected to the valve stem 2 and under a flow of pressurized air, the one way valve stem 3 will automatically depress permitting air to be pumped into the water conduit until a suitable pressure is developed eg. 40 to 80 PSI. If the gauge reading remains stable for a period of time commensurate with the size and number of water conduits and which will be known to one skilled in the art, then there are no leaks in the system. Otherwise, if the gauge reading drops over a period of time, then there is obviously a leak in the system.
In a like manner, the gauge assembly 5 in this device may also be used to check the in-line pressure of water conduits to determine, for example, if adequate water pressure is available for fire fighting purposes.
Referring to Figures 4 and 5, in the embodiment illustrated, a one-way air valve 10, being identical to the valve 1 shown in Figures 2 and 3, is mounted on a conduit body 11 formed with an internal fluid passage 13. There is also mounted S on the conduit body a coupling ring 14 identical to ring 6 as shown in Figures 2 and 3 and used in conjunction with washer 15.
The flushing device illustrated in Figures 4 and 5 is used as follows. The ring 14 is tightly threaded into position on the st~n~rd outlet/inlet of water conduit 9 with the valve of the outlet/inlet turned to the off position. The water source of the water conduit system is shut off and the outlet at the lowest possible point of the system is opened. An air source is then connected to the valve stem 11, the actuator means is depressed and air is pumped into the water conduit. The water displaced by the pumped air entering the conduit is expelled from the water conduit through the open outlet.
Referring to Figure 6, in the embodiment illustrated, a one-way air valve 22 identical in design to valve 1 shown in Figures 2 and 3 is connected to on a conduit body 23 having an internal fluid passage, by means of a standard quick release component 24 . As an alternative, a combination one-way air valve and air pressure relief valve identical to that shown as 16 and 17 in Figure 7 or the gauge assembly 5 in Figures 2 and 3, may be connected to the conduit body in the same manner. As a further alternative, the quick release component can be used to connect the said conduit body directly to an air source.
The apparatus also includes, in the embodiment illustrated in Figure 6, a coupling ring 25 identical to ring 6 as shown in Figures 2 and 3.
The flushing device illustrated in Figure 6 is used as follows. The ring 25 is tightly threaded into position on a standard outlet/inlet of water conduit 9 with the valve of the outlet/inlet turned to the off position. The water source of the water conduit system is shut off and the outlet at the lowest possible point of the system is opened. The valve 22 is then connected to the quick release component 24 and an air source is in turn connected to the said valve, the actuator means is then 2~
-depressed and air is pumped into the water conduit. The water displaced by the pumped air entering the conduit is expelled from the water conduit through the open outlet.
Referring to Figure 7, in the embodiment illustrated, a one-way air valve 16 identical in design to valve 1 shown in Figures 2 and 3 and an air pressure relief valve 17 both mounted on a conduit body 18. There is also mounted on the conduit body a threaded coupling ring 19 which is identical in design and function to the ring 6 as shown in Figures 2 and 3.
The flushing device illustrated in Figure 7 is used as follows. The ring 19 is tightly threaded into position on the standard outlet/inlet of water conduit 9 with the valve of the outlet/inlet turned to the off position. The water source of the water conduit system is shut off and the outlet at the lowest possible point of the system is opened. An air source is then connected to the valve stem 16, the actuator means of the air valve is depressed and air is pumped into the water conduit. The water displaced by the pumped air entering the conduit is expelled from the water conduit through the open outlet.
This invention relates to a device for flushing water from conduits located in a house, trailer or the like.
More particularly, this invention relates to a device by which water conduits may be connected to a source of pressurized air for removing or discharging water from the conduits when required.
