An integrated over-flow protection valve

Abstract

The utility model relates to an integrated overflow protection valve, including valve body, multistage sensing assembly, intelligent control assembly and self -sealing execution assembly, be provided with valve core push rod and valve core body in the valve body, the self -sealing execution assembly includes drive assembly, the drive assembly is linked with valve core push rod through spiral spring, through multistage sensing assembly provides the composite signal of pressure difference and flow, has improved the accuracy of leak detection, especially the identification ability of small leakage, through intelligent control assembly can judge the leak type fast, adapts to different leak scene, through the direct connection design of self -sealing execution assembly and intelligent control assembly, eliminated the intermediate delay of traditional solenoid valve drive, improved the system response speed, satisfies the quick cut -off demand under the emergency such as burst pipe, through the electric signal output of intelligent control assembly direct trigger spring release potential energy, drive valve core push rod produces axial displacement, solves the mechanical response delay problem existing in solenoid valve drive.
