The throttling and well-killing manifolds are connected to the two sides of the blowout preventer respectively. The throttling manifold can realize throttling circulation and blowout through adjustment, and can adjust the pressure difference between the drilling pressure and the casing pressure; the well-killing manifold can use high-pressure mud to control blowouts and well kicks.

[0036] Furthermore, a movable ring 101f is provided at the bottom of the main conduit 101b, a slot 101g is provided at the top of the movable ring 101f, and a snap ring 101e is slidably provided inside the slot 101g, and the devices of the slot 101g on the movable ring 101f and the snap ring 101e on the main conduit 101b provide overall protection.
