JPH08257543A - Water storage tank connectable to indoor water supply pipe - Google Patents

Abstract

PURPOSE: To secure fresh water and to maintain the hygiene of drinking water during the suspension of water supply caused by droughts, earthquakes, and other disasters by installing a water storage tank having two or more joints for water supply and drain pipes which can be connected with an indoor water supply pipe in the upper part and connecting the tank with the indoor water supply pipe. CONSTITUTION: A water storage tank D is installed which has two or more joints A, B for water supply and drain pipes to which an indoor water supply pipe can be connected in the upper part. The tank D can be equipped with a joint C of a non-pressure valve. The joint B of the water supply pipe can be installed in the lower part if a check valve H is used. In this way, the tank D is connected with an indoor water supply pipe so that fresh water can be secured and the hygiene of drinking water can be maintained during the suspension of water supply caused by droughts, earthquakes, and other disasters.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) The present invention is intended to connect to an indoor water supply pipe to reliably secure fresh water and protect sanitation of drinking water when water is cut off due to lack of rain or an earthquake disaster. Is. (B) Conventionally, there are various water storage tanks, but even if water is stored in a plastic tank or other container in anticipation of running out of water, the bactericidal agent (chlorine) contained in tap water hits air or sunlight. Since this is only effective for a few days, when water is stored in conventional tanks and containers, it has to be replaced regularly, so this water storage tank will be installed in the middle of the water supply pipe indoors. Since the effect of the bactericide is replaced with fresh water, it can be used immediately as drinking water when water is cut off. (C) Even if there is a water storage tank to which a water supply pipe can be connected, it is natural that only the water supply pipe connection part is at the top and the drainage pipe connection part is installed at the bottom. In such a storage tank, a large amount of water is stored. Unless it is a tank, the water may be noticed only when the water in the tank is used up. (D) In addition, the water tank installed on the roof of a building with a different purpose is a facility to prevent a decrease in water supply pressure on the upper floor, and the purpose and structure are different from this water tank.

Claims (1)

Claims [1] A water storage tank which can be connected to an indoor water supply pipe having two or more connecting portions for an indoor water supply pipe as shown in FIGS. Even if the water supply / drainage pipe connection is provided in the lower part, the water storage tank with the structure where the tip of the water supply / drainage port is closer to the upper part than the lower part inside the tank is regarded as the same structure as the main water storage tank. Claim [2] is provided with a connection portion of a pressureless valve as shown in FIG. 1C,
Or a water storage tank that can be connected to the connected indoor water supply pipe. [3] When the water supply pipe connecting portion of FIG. 3B is installed at the position of FIG. 4B due to the location of the water storage tank, the arrangement of the indoor water supply pipe, etc. The check valve as shown in FIG. 4H A water storage tank that can be connected to an indoor water supply pipe equipped with or a water storage tank that can be connected to an indoor water supply pipe in which a device equipped with a backflow stop device is attached to the water supply pipe.
