    • A plug launching system includes a main body and a plug canister (102) disposed within the main body. The plug canister includes a liner (200), a first rotational assembly (120) disposed about the liner, wherein the first rotational assembly is configured to support a first plug disposed within the liner and selectively enable fluid flow from an annulus between the main body and the plug canister (102) to a central passage of the liner (200), and a second rotational assembly (118) disposed about the liner (200), wherein the second rotational assembly is configured to support a second plug disposed within the liner (200) and selectively enable fluid flow from the annulus between the main body and the plug canister to the central passage of the liner, wherein the first and second rotational assemblies are configured to be actuated independently from one another.
    • 插头发射系统包括主体和设置在主体内的插头罐(102)。 塞罐包括衬套(200),围绕衬套设置的第一旋转组件(120),其中第一旋转组件被构造成支撑设置在衬套内的第一塞子并且选择性地使流体能够从主体 和所述插塞罐(102)连接到所述衬里(200)的中央通道,以及围绕所述衬里(200)设置的第二旋转组件(118),其中所述第二旋转组件被构造成支撑设置在所述衬里 (200)并且选择性地使流体从主体和塞罐之间的环形空间流动到衬管的中心通道,其中第一和第二旋转组件被构造成彼此独立地致动。
