The invention discloses a sensor base body for a lever type pressure sensor. The sensor base body for the lever type pressure sensor comprises a press plate (1) on the sensor base body, a press plate support point (10) on the sensor base body, a sensor base body support arm (9), a sensor base body induction pressure transmitting rod connecting point (2), a sensor base body support arm support post (8), a sensor base body induction pressure transmitting rod (3), a sensor base body support arm support post press plate (7), a sensor base body press head (4) and a sensor base body substrate (6). The sensor base body for the lever type pressure sensor uses the lever principle and does not depend on elastic deformation, the material fatigue is avoided, and the life span can arrive at 2 years; the sensor base body for the lever type pressure sensor is formed in one die, bolts are not needed, and the consistency is guaranteed; the force of all the pressure points is the same, the linearity is high, and the late data processing is facilitated; the requirement for the processing precision is greatly lower than that of a circular arc-shaped base body.

The invention discloses an observation device for a microscopic flow field in a particle pore in liquidation. The observation device comprises a liquidation generation container, a water pressure monitoring system, a liquidation generation container fixing device, a dynamic pressure controller and a laser particle velocity measurement device. The liquidation generation container comprises a quartz glass sample container and a pressure transmission mechanism. A quartz glass ball and a brine sample are arranged in the quartz glass sample container. The pressure transmission mechanism is internally divided into two chambers by a rubber membrane, wherein one chamber is connected with the quartz glass sample container and the other chamber is connected with the dynamic pressure controller. The water pressure monitoring system comprises two pore water pressure gauges, wherein one pore water pressure gauge is arranged in the quartz glass sample container and the other pore water pressure gauge is arranged in the chamber connected with the dynamic pressure controller. The dynamic pressure controller injects pressure to the quartz glass ball and the brine sample arranged in the quartz glass sample container through the pressure transmission mechanism. The observation device for the mechanism research of the microscopic flow field in liquidation is provided.

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.

The invention relates to the field of new energy automobiles, in particular to a new energy automobile multi-stage brake power assisting device which comprises a baffle, a rectangular supporting plate, a special-shaped supporting frame, a brake pedal, an accelerator pedal and the like. A rectangular supporting plate is fixedly installed on the rear side of the baffle, a special-shaped supporting frame is fixedly installed on the rectangular supporting plate, a brake pedal is rotatably connected to the left side of the front of the baffle, and an accelerator pedal is slidably connected to the left side of the lower portion of the baffle. Pressure is applied to hydraulic oil in the hose through the pressure valve, the hydraulic oil transmits the pressure to the sliding brake pad, the sliding brake pad and the brake disc make contact and rub with each other to achieve the braking effect, meanwhile, the hydraulic oil transmits the pressure to the fixed brake pad, and the fixed brake pad and the brake disc make contact and rub with each other to achieve the braking effect. The fixed brake pad and the sliding brake pad brake the automobile at the same time, and the purpose of decelerating the automobile until the automobile stops is achieved.
