Metal sealing ball floating ball and fixed ball two structures, pole superhard sealing Gas safety burner valve from the main and auxiliary Gas safety burner valve, ball, seat, seat ring, seat support ring, the support sleeve, under the support shaft, bearings, brass aluminum safety gas taps sliding bearings and other components and the Gas safety burner valve stem. The overall use of two fixed dome design, the stem of coat type, dust and spray structure, packing compression plate structure using spring preload pressure ratio compression provides structure, spheres, hardened Gas safety burner valve seat sealing surface, the Gas safety burner valve aNTI media sedimentary structure, advanced Gas safety burner valve seat polyethylene years of pilot operated safety valve manufacturing experience and innovation double blade and a compression spring or disc spring dust protection design, a blade in the seat sealing surface, another scraper at the top of the seat. The difference between small-caliber ball floating ball gas cooker safety valve stem with a fixed formula for downloading anti-ejection structure, as well as innovative structural freely rotating ball rolling.
