Abstract

A diversion valve for recovery of waste water comprises a waste pipe containing an apertured member forming the end of a conduit which passes through and is secured to the wall of the waste pipe. Rotation of the member causes it to oppose the flow of water through the waste pipe and to divert the flow through the aperture into the conduit. Preferably the conduit is supported rotatably by the wall of the waste pipe and rotation of the member is effected by rotation of the conduit. <IMAGE>

Description

SPECIFICATION Improvements in or relating to diversion valves and to drainage systems containing the same This invention relates to an improved diversion valve for use in the recovery of waste warer and to improved drainage systems containing the same.

Water has always been a relatively valuable commodity in countries of low rainfall and even in other countries where water is more freely abundant the growth of populations and the failure of the water utilities to keep pace with rising public demand have resulted in water shortages becoming increasingly frequent especially during periods of drought. As å consequence domestic users of water have an increasing incentive to use certain effluents such as bath water and the effluents from domestic dish washers and laundry machines for horticultural and agricultural purposes and car cleaning when restraints are imposed by the authorities on the use of fresh water for these purposes. Nevertheless the practice of collecting these domestic effluents whether in buckets or other containers is both arduous and inefficient.Consequently the major proportion of all domestic effluents are allowed to run away to waste without further use. The purpose of the present invention is to facilitate the recovery and reuse of domestic and industrial effluents.

Accordingly this invention provides a diversion valve comprising a first conduit in which is located a member incorporating an aperture said member being attached to or forming part of an end of a second conduit which passes through and is supported rotata bly by the wall of the first conduit and means to effect rotation of the second conduit so that when the second conduit is rotated the member can be moved into a position opposing the flow of fluid through the first conduit and diverting the flow through the aperture into the second conduit.

This invention is illustrated but not restricted by the following drawings in which: Figure 1 illustrates a view in perspective of the invention valve in which effluent is passing undiverted through the first conduit.

Figure 2 illustrates the valve shown in Fig. 1 with the flow of effluent being diverted through the second conduit extending from the wall of the first conduit.

Figure 3 illustrates in perspective a section of the valve illustrated in Fig. 2.

Figure 4 illustrates a view in vertical section of the second conduit terminating in a member incorporating an aperture.

In the Figures a first conduit (1) has located within it a member (2) having an aperture (5).

Member (2) constitutes an extension of a second conduit (3) which passes through the wall of the first conduit (1) and is rotated within a fluid tight bearing (6) housed in the wall of the first conduit. Rotation of the second conduit can be effected by moving lever (7) clockwise or anticlockwise.

In Fig. 1 member (3) is substantially parallel to the direction of flow of the effluent and there is a sufficient space between the member and the wall of the main conduit (1) to allow the effluent to run away to drain with the minimum of restriction. However if the effluent is required forrreuse, lever (7) is moved anticlockwise through 90 degrees. This results in member (2) which comprises soft resilient material to rotate and to form a close fit within the bore of the first conduit (1) as depicted in Figs. 2 and 3. As a consequence the passage of the effluent through the main conduit (1) is blocked and the effluent is diverted through the aperture (5) into conduit (3).

The invention valve can be made of ma teriais normally encountered in the plumbing and engineering trades or professions for example steel or plastics. The valve can be inserted in any convenient part of a drainage system for example at the exit of a kitchen waste pipe. Effluent diverted can either utilise gravity for its movement. However where this is not possible a pump can readily be incorporated in the second conduit preferably immediately after the invention valve in which case lever (7) can be adapted to act as a switch for the pump as well as controlling the movement of the member (2). Effluent passing through the second conduit can be led directly to the point of use or it can be discharged into a waste storage tnak for accumulation and use later.

It will be appreciated that whilst this invention is intended primarily for the recovery and reuse of waste water present in domestic and industrial effluents the invention valve can be used for diverting the flow of a wide range of fluids. Consequently the scope of this invention should be construed as extending to other systems utilising the valve.

1. A diversion valve comprising a first conduit in which is located a rotatable member incorporating an aperture said member being attached to or forming part of a second conduit which is secured to the wall of the first conduit and means to effect rotation of the member so that when it is rotated into a position so as to oppose a flow of fluid in the first conduit the flow is diverted through the aperture into the secnd conduit.

2. A diversion valve according to Claim 1 wherein the second conduit passes through and is supported rotatably by the wall of the first conduit and means to effect rotation of the second conduit so that when the second conduit is rotated the member can be rotated
