Abstract

A water-gas linkage valve includes a water valve body assembly (1) with a high pressure water chamber (121), a gas valve body assembly (2), a linkage assembly (3) for connecting the gas valve assembly (2) with the water valve body assembly (1), and a low pressure water chamber (122). A gas outlet (32) is provided in the linkage assembly (3). The low pressure water chamber (122) is connected with the high pressure water chamber (121) by a venturitube (13). The low pressure water chamber (122) is provided in the water valve body assembly (1). A pressure transmission unit is formed when the water valve body assembly (1) is connected with the linkage assembly (3). The pressure transmission unit is isolated from the high pressure water chamber (121) and the low pressure water chamber (122) by a diaphragm (131,132). The linkage assembly (3) is controlled by the water valve body assembly (1) based on the change of the pressure difference between the high pressure water chamber (121) and the low pressure water chamber (122), and then the linkage assembly (3) controls the open and close of the gas in the gas valve body assembly (2). Since the high and low pressure water chambers (121,122) are isolated from the linkage assembly (3) by the diaphragm (131,132), it avoids the water directly touching with the metal parts of the linkage assembly and effectively prevents sediment incrustation and corrosion.
