The invention belongs to the technical field of high-pressure plunger pumps, and discloses a high-pressure slurry pump fluid end which comprises a valve box, a stuffing box assembly, a liquid inlet and outlet valve set, a plunger and an oil injector. A plunger working cavity, a valve cavity, a liquid inlet and a liquid outlet are formed in the valve box, the plunger working cavity is communicated with the valve cavity, one end of the stuffing box assembly is connected with the valve box, the plunger is in sliding connection with a cavity in the stuffing box assembly, one end of the plunger extends into the plunger working cavity, and the liquid inlet and outlet valve set is arranged in the valve cavity. The two ends of the cooling water inlet pipe are communicated with a waterway inlet and a waterway outlet of the stuffing box assembly respectively. The slurry medium flows from top to bottom and is consistent with the deposition direction of abrasive particles due to gravity, so that the abrasive particles in the clearance volume are easily and smoothly discharged out of the pump; and the conditions that a flow channel is blocked and key parts are damaged due to deposition of abrasive particles in a traditional bottom-in and top-out type fluid end are avoided.

This utility model discloses a pet water dispenser, including a clean water tank and a waste water tank, which are connected as one unit by a mounting body. A drinking tray is provided on the waste water tank, and the drinking tray is equipped with a closure for discharging water from the drinking tray into the waste water tank. The mounting body is equipped with a water delivery mechanism for conveying water from the clean water tank to the drinking tray, and a magnetic component and controller for controlling the opening and closing of the closure. The controller controls the opening and closing of the magnetic component to activate the closure. This utility model is designed to automatically open and close the fresh water supply, ensuring pets drink fresh water and avoiding the situation where circulating filtered water cannot completely filter microorganisms, bacteria, food debris, and secretions, thus preventing pets from drinking waste water.

The application discloses a fly-wing door for a heavy truck battery swap station, which comprises a container and a fly-wing door body arranged on the container. The fly-wing door body is rotatably arranged on the side of the container. The two sides of the container are provided with driving members through fixing mechanisms. The output ends of the two driving members are matched with the fly-wing door body. The two fixing mechanisms are adapted to fix the corresponding driving members. The fly-wing door body is rotatably arranged on the two sides of the container. The two sides of the container are provided with driving members through fixing mechanisms. The output ends of the two driving members are matched with the fly-wing door body. When the fly-wing door is opened, the driving members are operated to rotate the fly-wing door body at the installation position, thereby opening the container for battery swap. The opened fly-wing door body is connected with the container, so that the fly-wing door body can be more stably opened, the fly-wing door body is automatically opened, the opened fly-wing door body is fixed, and the fly-wing door body is more safe and practical.

The invention relates to a heat-insulation sealed commercial electric door, and relates to the technical field of door and window buildings, the heat-insulation sealed commercial electric door comprises a door frame, door leaves, a driving assembly and a sealing assembly, the door frame is vertically arranged and fixedly connected in a wall body, a hanging plate is arranged at the top end of the door frame, the number of the door leaves is two, and the driving assembly is arranged in the door frame. Each group of door leaves comprises a fixed door leaf and a movable door leaf, the fixed door leaf and the movable door leaf are vertically arranged and are matched with the door frame, the fixed door leaf is fixedly connected to one side of the inner edge of the door frame, the movable door leaf is connected into the door frame, and the fixed door leaf is matched with the movable door leaf. The movable door leaf and the fixed door leaf are arranged in parallel along the inner edge of the door frame, the driving assembly is used for driving the movable door leaf to move, and the sealing assembly is used for forming a sealing state between the door leaf and the door frame as well as between the fixed door leaf and the movable door leaf. The commercial door has the effect of improving the heat insulation sealing performance of the commercial door.

The utility model belongs to the technical field of metro engineering, and particularly discloses an anti-pinch detection metro shielding door body structure which comprises a track, door frames are fixed to the two sides of the track respectively, a left door plate is movably connected between the track and the left door frame, and a right door plate is movably connected between the track and the right door frame. Sliding grooves are formed in the upper portion and the lower portion of the interior of the rail correspondingly, and a vertical groove is longitudinally formed in the outer side of the door frame. The left door plate and the right door plate on the two sides of the door body structure of the anti-pinch detection metro platform screen door are connected to the outer sides of the lead screws in a sleeving mode through the threaded sleeves, after the motor is controlled by the controller, the worm can be rotated in the vertical groove, then the two sets of worm gears meshed behind are pushed and rotated, the lead screws are guided to horizontally move the threaded sleeves, and the left door plate and the right door plate can conveniently and horizontally enter and exit from the door frame; whether a human body or an object is clamped by the left door plate and the right door plate is tested through emitted and received infrared rays, and the problem that the door plates are inconvenient to open and close is solved.
