Abstract

An improved water-gas linkage valve of a steam generator comprises a gas adjusting valve, a water valve, a rubber diaphragm and a thrust spring. A valve element cavity is formed in a valve body. A water inlet pipe is communicated with a flange inner cavity. The water inlet pipe and a water outlet pipe are communicated with the valve element cavity. The water-gas linkage valve further comprises a valve rod, a valve element, a valve element sleeve and a valve element base, one end of the valve element sleeve is open, the valve element sleeve is arranged in the valve element cavity, and the open end of the valve element sleeve is opposite to the water inlet pipe. The valve element base is fixed to the open end of the valve element sleeve, and a thread part of the valve rod is matched with a threaded hole of a top plate of the valve element sleeve and stretches out of the valve element sleeve; a guide part in the middle of the valve rod and an inner cavity of the valve element sleeve are in liquid seal and in running fit; the valve element is matched with an inverted-cone-frustum-shaped hole of the valve element base; an annular groove of the valve element sleeve is opposite to a water guide hole in the joint of the water outlet pipe and the valve element cavity. The water yield can be controlled by rotating the gaps between the valve rod, the valve element and the inverted-cone-frustum-shaped hole of the valve element base, and then the steam generation amount can be controlled. The improved water-gas linkage valve can be conveniently applied to food processing.
