Abstract
A mechanical joint including a circular seal (4), a gland ring (5), an elastic ring (6) and a back-up ring (7), as well as a body (1), with closure and backing part (2), while the joint can further contain a counterseal as an option, the body can further contain the closure and backing part as an option, and the elastic ring (6) is optionally equipped with two symmetrical pitch union nuts (9, 10) and two gaskets (11, 12), as well as with a symmetrical pitch screw (13). The joint has application to all pipe couplings, with alignment stress or with misalignment tolerance.
Claims18
A coupler for joining two sections of pipe, comprising at least one coupling unit comprising:
- (a) a body portion having an interior cavity defined by an inner surface of the body portion for receiving an end of a pipe;
- (b) an annular seal, said annular seal being sized to fit against the inner surface of the body portion, and being disposed in the interior cavity of the body portion;
- (c) an annular gland ring, said annular gland ring being sized to fit against the inner surface of the body portion, and being disposed in the interior cavity of the body portion adjacent to the annular seal;
- (d) an annular back-up ring, said annular back-up ring being sized to fit against the inner surface of the body portion, and being disposed in the interior cavity of the body portion adjacent to the annular gland ring on a side opposite the annular seal;
- (e) a split elastic ring having an annular portion and two end portions, said annular portion being sized to fit against the inner surface of the body portion and being disposed in the interior cavity of the body portion such that closing of the split elastic ring by bringing the end portions together results in compression of the gland ring and the back up ring between the split elastic ring and a pipe disposed within the body portion;
- and
- (f) a screw, engaged with the ends of the split elastic ring, said screw being turnable to open or close the distance between the two ends of the split elastic ring and loosen or tighten the annular portion of the split elastic ring.
A method for coupling two sections of pipe comprising the steps of inserting an end of a first section of pipe into a coupler comprising at least one coupling unit comprising:
- (a) a body portion having an interior cavity defined by an inner surface of the body portion for receiving the end of a pipe;
- (b) an annular seal, said annular seal being sized to fit against the inner surface of the body portion, and being disposed in the interior cavity of the body portion;
- (c) an annular gland ring, said annular gland ring being sized to fit against the inner surface of the body portion, and being disposed in the interior cavity of the body portion adjacent to the annular seal;
- (d) an annular back-up ring, said annular back-up ring being sized to fit against the inner surface of the body portion, and being disposed in the interior cavity of the body portion adjacent to the annular gland ring on a side opposite the annular seal;
- (e) a split elastic ring having an annular portion and two end portions, said annular portion being sized to fit against the inner surface of the body portion and being disposed in the interior cavity of the body portion such that closing of the split elastic ring by bringing the end portions together results in compression of the gland ring and the back up ring between the split elastic ring and a pipe disposed within the body portion;
- and
- (f) a screw, engaged with the end portion of the split elastic ring, said screw being turnable to open or close the distance between the two end portion of the split elastic ring and loosen or tighten the annular portion of the split elastic ring;
- and
- turning the screw to close the distance between the ends of the split elastic ring to establish a tight mechanical coupling between the coupling and the end of the first section of pipe.
