초록 ▼

A coupling device adapted for connecting conduits or the like which carry pressurized fluid and essentially embodies first and second coupling members, a pair of sealing members and retaining means. The first coupling member is arranged to be connected to the conduit and includes first and second spaced generally peripheral grooves, each of which is defined by respective first and second pairs of shoulders, and a peripheral depression formed adjacent one of the second pair of shoulders remote from the first groove. The pair of sealing elements are arranged such that respective ones thereof are suitably received within the first and second grooves for providing a fluid-tight seal. The second coupling member detachably receives the first coupling member and includes at least first and second bores which respectively slidably receive the first and second sealing members, and first and second openings which extend generally transversely to the longitudinal axis of the first and second bores. Such first and second openings are arranged adjacent to and in open communication with opposite sides of the peripheral depression formed on the first coupling member. The retaining means includes a pair of retaining members, each of which is respectively adapted to frictionally cooperate with the first and second openings and with the peripheral depression so as to interlock the first and second coupling members together, and for deforming the one shoulder formed adjacent the peripheral depression such that the first coupling member may not be slidably received by the first and second bores.

In a coupling device for connecting a conduit or the like carrying pressurized fluid comprising a first coupling member having first and second spaced generally peripheral grooves, each of which is defined by respective first and second pairs of shoulders and a peripheral depression formed adjacent one shoulder of said second pair of shoulders which is remote from said first groove; a pair of sealing members each of which is respectively received within said first and second grooves for effecting a fluid-tight seal; second coupling member positioned over said first coupling member with a tolerance therebetween and being detachably connected to said first coupling member and having at least first and second bores slidably receiving said firsT and second sealing members, and first and second openings extending generally transversely to the longitudinal axis of said first and second bores and each being arranged adjacent to and in open communication with an opposite side of said peripheral depression; and retaining means including a pair of retaining members each of which respectively frictionally cooperates with said first and second openings and said peripheral depression to interlock said first and second coupling members together, and which deforms at least a portion of said one shoulder so as to flare generally radially outwardly into frictional engagement with said second bore to close the tolerance between said one shoulder and at least a portion of said second bore, said second bore being dimensioned to enable said frictional engagement, whenever at least a predetermined proportion of a burst pressure is reached such that said first coupling member may not be slidably received by said first and second bores for enabling interlocking of said first and second coupling members by said retaining means whenever said first coupling is attempted to be reinserted in said second bore.
