Abstract

The utility model relates to the technical field of coating conveying, and discloses a mechanical coating pressure regulator which comprises an inlet pipe, the top of the outer wall of the inlet pipe is in threaded connection with an adjusting screw pipe, the inner wall of the adjusting screw pipe is fixedly connected with a limiting ring, and the top of the limiting ring is fixedly connected with a tension spring. The top of the tension spring is fixedly connected with a blocking ball, the top of the adjusting screw pipe communicates with a bottom cylinder, the top of the bottom cylinder is provided with a top cover cylinder, and the top of the top cover cylinder is provided with a plurality of fixing screws. According to the pressure adjusting device, the adjusting screw pipe enters the partition ring of the bottom cylinder, the adjusting screw enables the extrusion disc to slide in the shell, the spring is extruded, the limiting disc and the limiting chuck are clamped, when the pressure of the coating exceeds the elastic potential energy of the spring, the limiting chuck ascends, the coating flows out of the right side of the chuck and enters the connecting port, and pressure adjusting is achieved.
