The application provides a double butterfly plate type communication pipe regulating valve, and relates to the technical field of valves.The valve seat is internally formed with a medium passage, the medium passage is internally provided with a rotatable first butterfly plate, the first butterfly plate can open or close the medium passage when rotating, a middle through hole is formed in the first butterfly plate, the middle through hole is internally provided with a rotatable second butterfly plate, and the second butterfly plate can open or close the middle through hole when rotating;the rotating shafts of the first butterfly plate and the second butterfly plate are coincident with a preset axis, and a torsion piece is arranged between the rotating shafts;when the medium passage needs to be opened, the second butterfly plate is first rotated to gradually open the middle through hole, so that the torsion piece is twisted and stores torsion force; because the release direction of the torsion force is the same as the rotating direction of the first butterfly plate when the medium passage is opened, the torsion force can assist the first butterfly plate to rotate and open the medium passage when the first butterfly plate rotates, so that the opening of the regulating valve is more labor-saving.

This utility model discloses a press-type combination fresh-locking bottle cap in the field of bottle cap technology, including a cap body, a welding ring, and an insert post. The welding ring is located at the top of the cap body, and the insert post is located inside the cap body. The inside of the cap body is provided with a liquid storage chamber, and an aluminum foil film is adhered to the bottom of the liquid storage chamber. A welding groove is opened at the top of the cap body, and the welding ring is welded inside the welding groove. A pressing post is provided inside the welding ring, and an insertion hole is opened at the bottom of the pressing post. A telescopic ring is provided between the welding ring and the pressing post, and the insert post is inserted into the insertion hole. An installation ring is fixedly connected to the outside of the insert post, and a top tooth is fixedly connected to the bottom end of the insert post. A connecting rod is fixedly connected to the bottom of the installation ring. This press-type combination fresh-locking bottle cap has a reasonable structural design, which can improve the stability when pressing and avoid tilting, while making it easier to open the aluminum foil film.

The utility model relates to the technical field of anti-radiation doors, in particular to an anti-radiation air-tight door, which adopts a sealing ring which can exhaust air and is provided with a groove to suck a door body in a sucker shape, so that the door body is labor-saving to close, and the air-tight reliability is improved. Comprising a door frame and a door body, an annular air exhaust channel is formed in the door frame, the panel is installed on the front end face of the door frame, the multiple inner holes are formed in the panel and communicated with the air exhaust channel of the door frame, the rubber ring is installed on the front end face of the panel, the section of the rubber ring is in a U shape, and the outer hole is communicated with the air exhaust channel of the door frame. An annular groove is formed in the middle of the front end face of the rubber ring, a plurality of outer holes are formed in the bottom of the groove of the rubber ring and are aligned with the inner holes respectively, the air extractor is installed on the rear end face of the door frame, and the air extraction end of the air extractor extends into the air extraction channel of the door frame.
