초록 ▼

A coupling has first and second tube portions joined by a control collar that is rotatable to axially position the first and second tube portions in an installed position, a locked position and in a blow-off position. In the locked position, the tube portions are axially inserted and rotated and locked together by a biasing spring against separation and an O-ring member on one tube portion seals against the other tube portion to seal the tube portions together to prevent fluid leakage therefrom when in their locked position. The other tube portion includes a relief port which is opened for safety blow-off of pressure when the one tube portion is positioned in the blow-off position.

대표청구항 ▼

A tube coupling having a first tube and a second tube joined together by axial insertion into one another and relative rotation therebetween characterized by: said first tube having an outer surface and relief port in the end thereof communicating the interior of said first tube with said outer surface; a control collar having a flange portion thereon secured to said first tube and a hollow cylindrical portion telescopingly receivable on said second tube and further having cam surface means thereon including a lock portion and a pressure relief portion; cam follower means on said second tube selectively engageable with said cam surface means at said pressure relief portion and said lock portion when said second tube is inserted into said control collar and rotated with respect to said control collar to axially position said first tube in blow-off and lock positions; means located within said control collar for applying an outwardly directed biasing force on said second tube when it is inserted into said control collar to hold said cam follower means against said lock portion to prevent separation of said first and second tubes; said second tube having an annular groove and an O-ring seal supported in said annular groove adapted to engage and seal the outer surface of said first tube for preventing escape of fluid through said relief port when said first tube is in its lock position; said O-ring seal positioned outboard of said relief port when said first tube is in its blow-off position to relieve pressure from said first and second tubes before they are fully separated.
