Abstract
A pipe connector has a coupling (22) with a first cylindrical land (34), a second cylindrical land (36), and a third cylindrical land (38).
There is a first annular recess (42) defined between the first cylindrical land (34) and the second cylindrical land (36), and a second annular recess (44) defined between the second cylindrical land (36) and the third cylindrical land (38). A gate channel (50) communicates between the two recesses (42, 44) through the second cylindrical land (36).
Circumferential seals (46, 48) extend around the first and third cylindrical lands (34, 38).
A cement injection port (52) communicates between the outside of the connector of the first recess (42), and a cement vent port (54) communicates between the outside of the connector and the second recess (44). In use, a pipe (24) is inserted into the coupling to rest upon the three lands (34, 36, 38), and cement is forced into the injection port (52). The cement flows circumferentially around the first annular recess (42), through the gate opening (50), circumferentially around the second annular recess (44), and out through the vent port (54). The seals (46, 48) prevent the cement from flowing out of the interior of the connector.
