Novel throttling kill manifold device

Abstract

The utility model relates to the technical field of throttling well killing manifolds, in particular to a novel throttling well killing manifold device which comprises a blowout preventer connected with a well mouth, and a first flange connected with the two ends of the blowout preventer is connected with a second flange through bolts. The flange has the beneficial effects that when the first flange and the second flange need to be connected, the first flange and the second flange can be in threaded connection only through quick positioning, when the first flange and the second flange are in butt joint and butt joint is not successful, whether the convex hull on the second flange is in the sliding groove or not is observed, and if the convex hull is in the sliding groove, the distance between the first flange and the second flange is shortened, the flange can be connected. At the same time, when the first flange and the second flange are in threaded connection, the sealing gasket embedded in the second flange can be pressed into the clamping groove to achieve sealing, the sealing gasket is located on the outer side of the convex hull and the outer side of the sliding groove, and therefore the sealing effect of the first flange and the second flange is improved. And the sealing gasket is difficult to slide off due to the blocking of the convex hulls.
