"두 가지 밸브의 작동 유형에는 차이가 있습니다:"B형은 밸문후 압력을 조절하는 밸프후 압력 조절이고 K형은 �缬前取压是为了减压用选用气关式调节阀,正常时阀门是开着的,阀后压力高了就关闭阀门减小阀后压力。阀前取压是为了泄压用的的选用气开式调节阀,正常时阀门是关着着开着,阀前压力高了就打开阀门泄压。因此阀前取压是气开阀,阀后取压是气关阀,二者结构不一样所以不能通用。",

"バル브앞의 압력은 정상적으로 밸브가 열려있을 때 압력이 높아지면 밤폴를 닫아 밤폴 뒷 압력을 낮춥니다。バル브뒤의 압력은 정상적으로 밤폴이 닫혀있을 때 압력이 높아지면 밤폴을 열어 압력을 낮춥니다。따라서 밤폴앞의 압력은 기개식 밤폴이고 밤폴뒤의 압력은 기닫식 밤폴이며 두者的结构不同所以不能通用。",
