AN ASSEMBLY FOR RETAINING A SEAL RING IN A SEATING SURFACE OF A VALVE BODY |
摘要 |
<p>An assembly for retaining a seal ring (74) in a seating surface of a valve is provided having a circumferential groove (70) disposed in the seating surface for receiving the seal ring. The groove has a pair of substantially opposed side walls (a1) and (a2), one of which includes a first retention member (76) extending into the groove (70). The opposite side wall (92) is provided with a circumferential slot (80) which is accessible from outside the valve sealing surface through a passage (86). A second circumferential retention member (82) is inserted into the slot (80) throughout the passage (86) and protrudes into the groove (70) such that both retention members cooperate to retain the seal ring (74) within the seating surface.</p> |
