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. |
