4results about How to "Affect the sealing effect" patented technology

This invention relates to the field of underground gas storage technology for compressed air energy storage power stations, specifically to a large-size sealed door structure for high-pressure underground gas storage. It includes a sealed door, a sealing ring fixing steel plate, a first sealing ring, and a second sealing ring. A maintenance passage is provided inside a reinforced concrete plug. The sealed door is connected to the reinforced concrete plug via a sealing door support hinge. The maintenance passage is connected to the gas storage through the sealed door. The sealing ring fixing steel plate is fixed between the sealed door and the reinforced concrete plug. Both the first and second sealing rings are interference-fitted between the sealing ring fixing steel plate and the sealed door, with the first sealing ring positioned outside the second sealing ring. The sealed door structure is simple, adaptable to complex operating conditions, and ensures durability and reliability. It employs conventional sealing methods to form two seals, creating a double-layered protective barrier, resulting in good sealing performance, simple maintenance, and low repair costs.

The utility model provides a weighing bin used for a rapid loading station, which relates to the technical field of weighing bins and comprises a support, a stock bin is fixedly connected to the outer surface of the support, a plurality of weighing sensors are arranged on the outer surface of the stock bin, a frame is arranged at the bottom end of the stock bin and fixed on the outer surface of the support, and the weighing sensors are arranged on the outer surface of the frame. A hydraulic rod is arranged at one end of the frame, a cleaning device is arranged on the outer surface of the valve plate, the cleaning device comprises two threaded cylinders and two threaded rods, and a plurality of scraping blocks are fixedly connected to one ends of the threaded cylinders. When a hydraulic rod operates to drive a valve plate to move, threaded barrels on the two sides of the inner wall of the valve plate can rotate, scraping blocks are driven to rotate to scrape and clean materials on the moving path of the valve plate on the inner wall of a frame, and the situation that the moving path of the valve plate is blocked due to the fact that the materials are stacked on the inner wall of the frame, and the sealing effect of the valve plate on the bottom of the stock bin is affected is avoided. And the stability of the weighing bin in use is improved.

The utility model discloses a laundry condensation pearl packaging device, including base, the base upper end fixed mounting has support frame, hopper, the hopper fixed mounting is in the support frame upper end, with hopper bottom fixedly connected with the discharge pipe, and the discharge pipe outside fixed mounting has solenoid valve, water -soluble film round forming machine, water -soluble film round forming machine fixed mounting is in the discharge pipe outside. This laundry condensation pearl packaging device when needing to encapsulate laundry condensation pearl, first through the controller control solenoid valve operation to make the discharge pipe to the round bottom membrane body of lower extreme fills certain weight material, fills after the completion, and runs servo motor, and servo motor output end drives the screw rod of opposite direction rotation to drive the screw connector of two -end screw connection to move towards, through the opposite movement of two groups of screw connector to drive the heat -seal plate of two -end heating and move towards, paste in the upper end sealing of round bottom membrane body, the upper end of round bottom membrane body is sealed.

This invention relates to the field of door frame technology, specifically an S-shaped door frame structure, comprising: a door frame; a sealing device disposed inside the door frame and extending to the surface of the door frame; wherein, the sealing device includes a side sealing mechanism longitudinally disposed on the surface of the door frame, a sealing adjustment mechanism disposed on one side of the side sealing mechanism, a top sealing mechanism disposed between the two side sealing mechanisms, and an anti-pinch mechanism disposed on the side of the side sealing mechanism away from the sealing adjustment mechanism, the anti-pinch mechanism extending to the outside of the door frame; the side sealing mechanism includes a hinge, a push-acting assembly, and a sealing assembly; by providing the side sealing mechanism and the top sealing mechanism, the contact area between the door panel and the door frame can be sealed under the action of the side sealing mechanism and the top sealing mechanism, reducing wear caused by opening and closing the door panel, thereby ensuring the sealing effect of the gaps.
