1results about How to "Good anti-drip effect" patented technology

The application relates to a drip-proof gravity back-suction structure of a high-viscosity vinegar filling valve and relates to the technical field of filling valves, which comprises a valve body, the inner side of the valve body is provided with a valve core assembly, and the valve core assembly comprises a valve core main body which is slidably connected to the inner side of the valve body. The application is characterized in that the valve core assembly is arranged on the inner side of the valve body, the back-suction channel in the inner side of the valve core main body is matched with the communicating pipe, the collecting box and the negative pressure adsorption assembly on the outer side of the valve body, after filling is completed, the second cylinder in the negative pressure adsorption assembly drives the piston plate to move upwards, a negative pressure is formed in the collecting box, the high-viscosity vinegar liquid remaining in the valve port is timely sucked into the collecting box through the back-suction channel, the problem that the residual vinegar liquid is difficult to clean and dripping frequently in the conventional technology is effectively solved, the structure can be adapted to filling of vinegar liquids with different viscosities, the application range of the conventional technology is broken through, meanwhile, the taper matching structure of the valve core main body and the valve body is combined with the first sealing ring, the rubber sleeve and the second sealing ring, the sealing performance is enhanced, and the drip-proof effect is improved.
