Abstract
The utility model discloses a two-way non-return valve for a water purification machine. The two-way non-return valve comprises a raw wastewater box, an upper water-stop valve and a lower water-stop valve, wherein the upper part of the upper water-stop valve is fixed at the bottom of the raw wastewater box, and the upper part of the lower water-stop valve is connected to the lower end of the upper water-stop valve in a sleeving manner. According to the two-way non-return valve disclosed by the utility model, once the upper water-stop valve and the lower water-stop valve are separated, an upper water-stop shaft in the upper water-stop valve seals a water inlet in the bottom of the raw wastewater box under the action of an upper spring, and a lower water-stop shaft in the lower water-stop valve seals a water inlet of a lower valve body on the lower water-stop valve under the action of a lower spring. Because the two-way non-return valve for the water purification machine, which is disclosed by the utility model, is not a conventional solenoid valve, no power supply is required, so that no damage is caused because a coil is overheated, and therefore, the two-way non-return valve for the water purification machine is low in failure rate.
