摘要： A sealing gasket is shown for use in a ductile iron piping system to form a sealed joint between mating male and female pipe ends. A sealing gasket body is provided with a series of retainer inserts which extend outwardly from a leading nose region of the elastomeric gasket body. The mating male pipe end contacts the retainer inserts prior to contacting the remainder of the gasket body during the make up of the pipe joint. The inserts help to retain the gasket within its associated groove during high pressure field conditions. The inserts are spaced circumferentially about the gasket nose region, allowing the gasket the necessary flexibility to allow insertion within the groove provided in the female, belled pipe end.

摘要： A coupling for connecting hydraulic ducts has a female coupling (1) with a receptacle and a first locking face arranged around a longitudinal axis. A male coupling (2) forms a second locking face, arranged around the longitudinal axis. The male coupling (2) can be inserted in the direction of the longitudinal axis (4) through an opening into the receptacle (3). A holding element (9) has a ring (10) with several spring elements projecting from the ring (10). The spring elements (11) extend parallel to the longitudinal axis (4). Locking elements (12) are formed on the free ends of the spring elements (11). The spring elements (11) are, respectively, elastically deformable against a spring force radially out of a locking position into a releasing position. In the inserted condition of the male coupling (2), the first locking face (15) and the second locking (16) face one another. Also, the locking elements (12) are supported in the locking position of the spring elements (11) on the first locking face (15) and on the second locking face (16).

摘要： A plug-in coupling for pressure application systems, including two coupling components such as a housing component and a connector component. The connector component is sealed insertable into a locating opening of the housing component, and is arrestable against loosening by a locking device. The locking device has an elastically deformable holding element, which is located on the side of one coupling component in such a way that, in the inserted state, it engages behind an arresting step of the other coupling component, locking with positive fit, for arresting said connector component. The holding element is designed ring-shaped and comprises several individual annular segments and one concentric spring lock washer component which presses the annular segments with radially operating spring resistance that each annular segment can move radially against or through the spring resistance of said spring lock washer component during the plugging-in.

摘要： A pipe joint and a locking member for use with the pipe joint are provided for a bell and spigot type joint, the locking member being a separate element disposed axially outwardly of a fluid seal gasket within the bell end of a first of the pipe elements, the locking member being made up of an elastomeric backing member and at least one locking segment, the elastomeric backing member being adapted to seat in a first annular recess in the bell end, and against a radially inwardly protruding shoulder, this seating position urging the outer surface of the locking segment into contact with the wall of the first annular recess, to effect a constant, positive wedging action against a spigot end of a second pipe element inserted into the bell end of the first pipe element. The locking member thus securely engages and retains the spigot end within the bell end against axial forces tending to separate the pipe elements, and the locking member serves as a dirt seal improving the prevention of dirt and other materials from entering the bell end of the joint which could adversely affect the integrity of the fluid seal or interfere with the ability to efficiently induce any desired joint deflection.

摘要： An annular sealing material seals a pipe joint between a socket and a spigot. The sealing material includes a bulb part which is composed of a first bulb, a second bulb located closer to the inner side of the socket than the first bulb, and a narrow part present between the first and second bulbs. The first bulb is pressed against the inner circumferential surface of the socket. The second bulb is pressed against the outer peripheral surface of the spigot. The second bulb is inclined towards the pipe center from the first bulb in a natural state before it is provided between the socket and the spigot. The inner diameter of the second bulb is smaller than the outer diameter of the spigot in the natural state. The second bulb is extensible in the pipe diameter direction due to elastic deformation of the narrow part.
