Detection device for automatically fixing pressure regulating valve

The invention relates to the related field of pressure regulating valves, and discloses a detection device for automatically fixing a pressure regulating valve. The detection device comprises a detection box, the detection box is internally provided with an exhaust cavity with a rightward opening, the upper side of the exhaust cavity is provided with a centrifugal cavity, the right side of the centrifugal cavity is communicated with a push plate cavity, and the upper side of the push plate cavity is communicated with a detection block cavity. A threaded lead screw shaft extending leftwards into the left end wall of the detection block cavity and extending rightwards to the outside is connected into the right end wall of the detection block cavity in a rotating fit mode, a pressure push plate moves rightwards to make contact with a pressure sliding block in an abutting mode to send a marking magnetic block, and therefore the detection result of the pressure regulating valve block is marked. The air pressure transmission block pushes the pressure regulating valve block to abut against the sealing induction coil to ensure the sealing performance, so that the detection result is more accurate, and meanwhile, the valve body detection block is driven to move left and right by rotating the setting knob, and thus the detection standard intervals of different types of pressure regulating valve blocks are adjusted, and the universality of detection is improved.
