A bidirectional valve and explosion-proof valve
This utility model relates to the field of valve technology, and in particular to a two-way valve and an explosion-proof valve. The two-way valve provided by this utility model includes a housing and a fixed base forming an air exchange channel, and a first movable member and a second movable member. At least a portion of the first movable member passes through the second movable member and extends into the fixed base. The first movable member is axially movable relative to the second movable member and the fixed base. When the first movable member moves in a first direction, the air outlet channel communicates with a first gap. When the first movable member pushes the second movable member to move in a second direction, the air inlet channel communicates with the first gap. The movement of the first movable member within the air exchange channel forms separate air outlet and air inlet channels, precisely controlling the airflow direction, avoiding turbulence and backflow, improving exhaust efficiency, and adapting to airflow pressure requirements in different directions.

A self-cleaning platform door for rail transit
PendingCN122078448ARealize dynamic cleaningreduce bring inRailway componentsPower-operated mechanismGear wheelBrush
This invention discloses a self-cleaning platform screen door for rail transit, belonging to the technical field of rail transit. It includes a door frame, with a motor mounted on the top of the frame. The output shaft of the motor is connected to a connecting shaft via a pulley mechanism. A gear is fixedly sleeved on the outer side of the connecting shaft, and a rack is fixed to the top of the platform screen door via a rod. It also includes a cleaning mechanism located on the inner side of the door frame. The cleaning mechanism cleans the surface of the platform screen door using a combination of sweeping and vacuuming. This self-cleaning platform screen door for rail transit, by combining a rolling cleaning brush with a vacuuming structure, achieves dynamic cleaning of impurities and dust on the platform screen door, avoiding problems of untimely cleaning and increased cleaning difficulty. Furthermore, the platform board connecting the platform screen door and the vehicle can absorb pedestrians' feet and fallen impurities and dust, reducing the amount of impurities and dust brought into the vehicle.

ActiveCN224212586UReduce citationsreduce usageGlass making apparatusGlass fiberStructural engineering
The utility model discloses a bundling plate which comprises a plate body, the plate body is provided with two bundling grooves, the two bundling grooves both penetrate through the upper surface and the lower surface of the plate body, notches of the two bundling grooves are oppositely arranged, one side of the plate body is provided with a notch, and the other side of the plate body is provided with a clamping groove. The plate body is provided with a notch, the notch is communicated with the two bundling grooves so that a plurality of bundled glass fibers can enter any bundling groove from the outside of the plate body through the notch or enter the outside of the plate body from any bundling groove through the notch, and the plate body is further provided with a connecting structure so that the bundling plate can be detachably connected to a bundling plate fixing part. The glass fiber bundling device can be applied to bundling of glass fibers in two directions, introduction of wire blocking materials (such as iron wires) can be reduced, tows can be introduced in the two directions without the iron wires, and the production cost is saved. The use of positioning iron wires is reduced, the wire leading time is saved by more than 5 seconds each time, meanwhile, metal brought into a spinning cake is reduced, and potential quality hazards are reduced.

Endotracheal intubation kit for protection against ventilator-associated pneumonia
This invention discloses an endotracheal intubation assembly for ventilator-associated pneumonia (VAP) protection, comprising an endotracheal cannula and a cannula. The endotracheal cannula includes a cannula body, with first and second air bladders mounted on its lower part, suspended from the ground. The first air bladder is connected to a first inflation port via a first inflation connecting tube, and the second air bladder is connected to a second inflation port via a second inflation connecting tube. A first suction port is located on the cannula body above the first air bladder, and a second suction port is located on the cannula body above the second air bladder. A suction connecting tube fixed to the cannula body has one end connected to a suction port and the other end extending to the locations of the first and second suction ports. A pH sensor is located on the cannula body below the second air bladder. The cannula includes a T-shaped bite pad, consisting of a cylindrical bite pad handle and a sheet-like bite pad head, with a cylindrical isolation membrane extending from the bite pad handle. This invention has advantages such as preventing secretions and pathogens from invading downwards, thus reducing the incidence of VAP.
