Abstract

The utility model relates to a freezing-proof valve for running water which is used as a running water tap. The freezing-proof valve for running water is composed of the standpipe (6) of a valve body, a valve core (8), a hand wheel (3) and a hand wheel shaft (2). When used, the valve core (8) of the utility model lies underground; the wall of the valve body (6) which is arranged on the upper part of the valve core (8) is provided with a drain hole (7); when the freezing-proof valve for running water is fastened up, the water of the upper part of the valve core (8) is drained from the drain hole (7). Because the portion of the utility model which lies on the ground is not filled with water after the freezing-proof valve for running water is closed, the freezing-proof valve for running water can not be frozen or freeze damaged because of cold weather.
