An automatic pressure stabilizing device for a piston compressor
ActiveCN224282859UShutters/ movable grillesPositive displacement pump componentsGear wheelControl theory
This utility model discloses an automatic pressure stabilizing device for a piston compressor, comprising an automatic pressure stabilizer: a protective switch is mounted on the surface of the automatic pressure stabilizer; a fixed base is bolted to the surface of the automatic pressure stabilizer; a rotating rod is rotatably connected to the inner wall of the fixed base; a roller shutter is mounted on the surface of the rotating rod; the automatic pressure stabilizer is fixedly connected to two symmetrically arranged limiting rails by bolts; and a U-shaped plate is fixedly connected to the surface of the fixed base. This utility model utilizes the roller shutter to slide and pull down within the inner wall of the limiting rails, thus shielding and protecting the protective switch. Furthermore, the unidirectional rotation of gear two locks the roller shutter in its rolling / unrolling state via the rotating rod, achieving the goal of shielding and protecting the protective switch on the surface of the automatic pressure stabilizer, preventing accidental activation of the protective switch, and thereby improving the safety of the protective switch during use.
