The utility model discloses a high-precision low-flow-resistance stop valve, belongs to the technical field of valves, and provides the following technical scheme for solving the problem that the flow pressure adjusting precision is reduced due to vibration of a valve clack of a traditional stop valve: the valve clack is connected with a valve rod through a plurality of groups of supporting assemblies which are uniformly distributed in the circumferential direction, and an inner rod and an outer rod form an axial telescopic structure; and the turntable is in running fit with the valve rod through the L-shaped connecting ring. An annular communicating groove is formed in the top of the valve clack, an annular connecting groove is formed in the corresponding position of the bottom of the valve clack, the two grooves are communicated through communicating holes in an annular array, and a sealing ring capable of being embedded into the connecting groove is arranged in the corresponding position of the inner wall of the valve cavity. When the valve is opened, fluid can directly penetrate through the valve clack through the communicating hole to reduce impact force, the supporting assembly counteracts lateral acting force of the fluid on the valve clack through the axial bearing structure, and bending deformation of the valve rod is prevented. According to the valve, the fluid control precision and the operation stability are effectively improved while the sealing performance is kept by optimizing the fluid channel shape and the valve clack supporting structure.

The adaptive grabbing and transporting unmanned aerial vehicle comprises a flying carrying module and a transporting box, the transporting box is provided with an annular flange matched with the four-point mounting system on the peripheral side, and the mounting and locking system of the square four motors is clamped and fixed; the mounting and locking system of the square four motors comprises four hollow cup motors distributed in a square shape; the tight clamping rope assembly is connected with a section of tight clamping rope on both sides of each hollow cup motor, the tight clamping ropes of the two hollow cup motors arranged oppositely are connected with each other to form a square tight clamping structure, and a variable opening for accommodating the transporting box is formed in the middle of the square tight clamping structure; and the controller is electrically connected with the four hollow cup motors and is used for controlling the four hollow cup motors to synchronously rotate in the forward direction or the reverse direction. The adaptive grabbing and transporting unmanned aerial vehicle has the mechanical self-locking function, is strong in environmental adaptability, supports one-key autonomous operation, and is compatible with various box sizes.

This invention discloses a prefabricated formwork panel composite wall structure, comprising a concrete formwork panel 1, connecting steel members 2, insulation board 6, wire mesh 7, structural column reinforcement 8, shear wall reinforcement 9, and cast-in-place concrete 10. The concrete formwork panel 1 has a trapezoidal protrusion 4 on its top surface and a trapezoidal groove 5 on its bottom surface, within which a reinforcing steel mesh 3 is installed. The reinforcing steel mesh 3 is composed of transverse thick steel bars 30, vertical thick steel bars 31, transverse thin steel bars 32, and vertical thin steel bars 33. The wire mesh 7 is composed of transverse steel wires 70, vertical steel wires 71, and fixing steel plates 72. The concrete formwork panel 1 is vertically located at both ends of the connecting steel members 2. One large surface of the insulation board 6 has the wire mesh 7 inserted, and the other large surface is in close contact with the concrete formwork panel 1. The insulation board 6 and the wire mesh 7 are located between two concrete formwork panels 1. The structural column reinforcement 8, shear wall reinforcement 9, and cast-in-place concrete 10 are all located between two concrete formwork panels 1.

This invention relates to the field of instant multivitamin beverage technology, specifically a dual-compartment, ready-to-use pet multivitamin instant beverage and its preparation method. The beverage includes a dual-compartment package consisting of a powder compartment, a liquid compartment, and an easy-tear aluminum foil diaphragm. The powder compartment is located on top of the liquid compartment and is integrated inside the bottle cap with a light-blocking, nitrogen-filled, and sealed structure. The liquid compartment is a food-grade PET bottle. This invention's dual-compartment, ready-to-use pet multivitamin instant beverage achieves long-term stable preservation of active ingredients through synergistic innovation of dual-compartment physical isolation, a highly active powder formula, and an instant-mixing process. The light-blocking, nitrogen-filled, and sealed powder compartment ensures long-term stable preservation of active ingredients, while the instant emulsification system enables instant dissolution and emulsification by hand shaking, without layering or floating oil.
