Abstract
The utility model discloses an anticorrosion gas plug valve which comprises a valve body, a valve plate rotary base, a valve cover, a valve rod, a knob, a spring and a microswitch mounted on the valve cover; the anticorrosion gas plug valve is characterized in that a fixed valve plate and a movable valve plate made of ceramics are mounted in the valve body. As two ceramic valve plates are arranged in the valve body of the plug valve, the two valve plates rotate oppositely to change the opening or closing state of the axial through holes, and regulate or cut off the gas input and output so that the firepower control of the outer ring and inner ring of the gas stove combustor are realized. When the plug valve with the structure is in use, only two circular ceramic plates are contacted with gas and provided with friction surface; meanwhile, the seal ring has no relative sliding and abrasion, and is sealed reliably. The anticorrosion gas plug valve has the advantages of anticorrosion, abrasion resistance, long service life, simple structure and low cost.
