DE19618124A1 - Hydraulic control for filling of WC bowls with two different water supplies depending on system pressure - Google Patents

Abstract

The container is connected up to a drinking water pipe (C) and a non-potable water pipe (B) which are each controlled by a float valve (E and D) in their inlets. A pipe (G) branches off at the feed to a small cylinder (H), to which it is connected. A piston moves in the cylinder under pressure from the non-potable water, which holds the drinking water inlet float in the top position (feed closed) via a linkage system. In the case of a loss of pressure from the non-potable source, the linkage system is depressed by a spring in the cylinder into the zero setting, and the drinking water valve float (E) can carry out its normal function. When non-potable water is once again available in the pipe, the stop position is once more set up for the drinking water due to pressure in the cylinder.

Description

The existing environmental conditions require savings dealing with what is in part elaborately obtained and expensive Drinking water. There are aspirations to waters other than Use drinking water for wastewater transport (rainwater, Well water, etc.).

The control has the purpose in the event of a failure of the useful water (empty pumped rainwater tank) immediately after drinking to change water.

The toilet cisterns are usually attached to the drinking water supply network connected and by an enema swim controlled by the valve.

For the purpose of supplying usable water, a second Line to the cistern and a second inlet float mounted in the box. This supply takes place usually via a house water pump.

In the supply line to the industrial water float valve branched a line to a small pressure cylinder, which is mounted on the drinking water float valve and if there is pressure in the process water line a short leverage the drinking water swimmer in in its upper position (inlet closed).

In the event of a loss of pressure in the process water supply (pumped empty Industrial water tank) is the locking rod by a Spring pressed into the zero position and the drinking water swimmer can start its normal function.

Service water is available again and pressure in this line the locking position for Drinking water initiated.

The hydraulic control can be retrofitted into existing ones Plants installed and also used for new installations will.

Different brands of floats can be used will.

The device can also be used in other float-controlled Systems find constitution.  

An embodiment of the hydraulic control is in the Drawing shown and is described in more detail below:

Reference list

A = toilet cistern, B = process water connection, C = drinking water connection, D = inlet float for process water, E = inlet float for drinking water, F = actuation button for rinsing  process, G = transfer of process water pressure to the pressure cycle linder, H = pressure cylinder to hold the drinking water running swimmers with existing pressure in the process water pipe.

In the drawing of the toilet cistern A, the container is at one Drinking water pipe C and a process water pipe B connected sen, each in the inlet by a float valve E + D are controlled.

In the supply line of the industrial water float B there is a line G branched to a small pressure cylinder H and with this connected. In the printing cylinder H is now in the presence of Working water pressure moves a piston that over the linkage Drinking water inlet float C in the upper position (inlet ge closed) holds.

In the event of a pressure drop in the utility water supply (empty pumped utility water tank) the rod is pressed by a spring cylinder H pressed back into the zero position and the drinking water float valve E can start its normal function.

If useful water is available again and pressure in this line G, becomes the blocking position for drinking by pressing the cylinder H. water restored immediately.

Claims (1)

There is claim for hydraulic control of the two float valves depending on a system pressure requested.
