    • PURPOSE: An automatic pressure regulating valve is provided to let a liquid flow out at the set pressure while minimizing the pressure variation of the liquid flowing into the main body. CONSTITUTION: An automatic pressure regulating valve(100) comprises a hollow main body(110), a variable pressure chamber(140), and a floating member(150). The main body has inlet ports(112) and outlet ports(114) connected to transfer pipes. The variable pressure chamber is provided on the upper part inside the main body and reduces the pressure of liquid flowing into the inlet ports using the Venturi effect, thereby vertically moving an opening/closing piston(130) inserted in a circulation cylinder(120). The floating member is arranged under the variable pressure chamber and moved between the inlet port and the outlet port by the liquid contained in the main body. A female and male structure(156) is formed on the bottom of the floating member.
    • 目的:提供一种自动调压阀,使液体以设定压力流出,同时使流入主体的液体的压力变化最小化。 构成:自动压力调节阀(100)包括中空主体(110),可变压力室(140)和浮动构件(150)。 主体具有连接到输送管的入口(112)和出口(114)。 可变压力室设置在主体内部的上部,并且使用文丘里效应降低流入入口的液体的压力,从而垂直移动插入循环筒(120)中的打开/关闭活塞(130)。 浮动部件布置在可变压力室下方,并通过主体中所含的液体在入口和出口之间移动。 在浮动部件的底部形成阴阳结构(156)。
