Abstract

The utility model discloses a convenient, water-saving and anti-freezing valve. The side face of a valve body of a conical body valve or a ball-shaped valve is drilled with an air inlet hole, and a central position on one side of a water inlet and water outlet holes of a valve core is drilled with a vent hole. When the valve is closed, the air inlet hole, the water inlet and the water outlet holes of the valve core and the vent hole on one side of the water inlet and the water outlet holes are communicated with a water inlet and a water outlet pipes, and thus air can enter. Thus water in the water pipes from the valve to users can be drained completely when the valve is closed. Because the valve and a water storage tank are directly arranged, the valve can be controlled by using a pull-cord switch or an electromagnetic switch. When water needs being filled in the water storage tank, the pull-cord switch is pulled, and the valve is opened. When water filling begins, the air inlet hole of the valve and the vent hole are closed automatically, and thus dominant conditions of the large area popularization and utilization of solar energy water heaters in the cold north are created because of the valve has the capabilities and advantages of water saving and anti-freezing.
