GAS VALVE WITH CERAMIC DISK ELEMENT

A gas valve comprising: a body (10) having an inlet passage (15) and an outlet passage (16) in gas flow communication via an internal chamber (1) enclosed by the body (10); a fixed disc element (30), which is fixed in the inner chamber (1) and has a through-hole (32) on the fixed disc element (30), which through-hole (32) opens to the gas outlet channel (16); a rotating disk element (40) having an inner wall (41), which overlaps the front wall (35) of the fixed disk element (30) in a rotatable manner, and a cavity (42), which, when rotated, leads to the outlet channel (16) through a through-hole (32). The front wall (35) of the fixed disk element (30) and the inner wall (41) of the rotating disk element (40), which face each other, are each made at least partially of a ceramic material. 一种气体阀，该气体阀包括：本体(10)，该本体(10)具有入口通道(15)和出口通道(16)，该入口通道和出口通道经由本体(10)围出的内部腔室(1)而处于气体流动连通；固定盘元件(30)，该固定盘元件(30)被固定在内部腔室(1)中，并且在固定盘元件(30)上具有通孔(32)，该通孔(32)敞开向气体出口通道(16)；旋转盘元件(40)，该旋转盘元件(40)具有内部壁(41)和腔体(42)，该内部壁(41)以可旋转的方式与固定盘元件(30)的前部
