  • Patent number: 11381067
    Abstract: An explosion-proof line bushing and method for producing the line bushing. A prespecified amount of elastomeric material is applied to a line and completely surrounds the line in a flat section in the circumferential direction. The line is inserted into a passage opening of a bushing body. The bushing body is preferably plastically deformed. After the plastic deformation, the elastomeric material substantially fills the volume remaining between the formed bushing body and line. The elastomeric material is elastically deformed and presses both against the line and the formed bushing body so that flame-proof gaps are formed between the bushing body and the line. The applied mass of the elastomeric material is determined depending on the inner volume between the formed bushing body and the line remaining.

  • Patent number: 9086179
    Abstract: A quick coupling pipe fitting system is disclosed that connects two ends of two different pipes together in a fluid tight manner. It is designed for convenience in installation, high strength, compact size, easy manufacture with a low production cost, high efficiency and does not require the use of special tools for installation. The coupling utilizes a grab ring module that has a grab ring made with embedded stainless steel, thereby strengthening the fixing force and allowing for quick installation. A flaring surface on a retaining flange has an angle that corresponds to a tapering surface of the grab ring module. When the flaring surface and the tapering surface contact each other, the grab ring module compresses the surface of the pipe. Because the grab ring module has an outer plastic body with a small inner part, the grab ring module can be compressed to the pipe without causing fatigue of any members inside of the fitting. A specialized tool allows for quick and easy dismantling of the fitting.

  • Patent number: 8801045
    Abstract: In a pipe joint, a release bush includes a cylindrical portion and a flange portion for pressing, provided along an outer edge of the cylindrical portion. A movable portion including a part of the flange portion and a part of the cylindrical portion is formed to move with respect to a main portion including the remaining part of the flange portion and the remaining part of the cylindrical portion, via an elastically deformable portion. The cylindrical portion of the movable portion can be moved to be aligned with the cylindrical portion of the main portion along the same circumference, by an external operating force exerted on the movable portion, while the movable portion remains in a position opposing a main body of the pipe joint when an operating force is not applied, thereby inhibiting the release bush from being pressed into a chuck despite the flange portion being pressed.

  • Patent number: 8474876
    Abstract: An anti-rotation key inserts into a pocket formed on an outer surface of a male threaded connector. The key has a lower inner side portion for contact with the base of the pocket. An array of teeth on a lower outer side portion of the key bite into an inner wall of a female threaded connector as the key is forced into the pocket. One of the edges of the key is configured such that a line tangent to the first side edge where it intersects the lower outer side portion will intersect a line tangent to a central portion of the lower inner side portion at an angle less than 90 degrees. Relative motion between the male and female threaded connectors in a loosening direction causes the key to pivot about an engagement of the first side edge with the first side wall and bite more deeply into the inner wall of the female threaded connector.
