用于阀的装置
摘要：
一种用于阀的装置包括：固定部（2；6），设有至少一个流体端口（214；634）；和可旋转套管（3；7），设有至少一个孔（33；72），其中：所述套管（3；7）被构造成允许所述套管（3；7）将所述孔（33；72）旋转为与所述流体端口（214；634）成一直线，从而当所述套管（3；7）处于打开位置时，所述套管允许流体流经所述流体端口（214；634）和所述孔（33；72）；所述套管（3；7）被构造成允许所述套管（3；7）将所述孔（33；72）旋转为远离所述流体端口（214；634），从而当所述套管（3；7）处于关闭位置时，所述套管不允许流体流经所述流体端口（214；634）；所述固定部（2；6）和所述套管（3；7）在所述固定部（2；8）与所述套管（3；7）之间形成环空（92；94）；并且所述环空（92；94）在所述套管（3；7）和所述固定部（2；6）的轴向上受到两个封隔器元件（37；69）的轴向限制，其中所述两个封隔器元件（37；69）中的一者位于所述流体端口（214；634）的一侧，所述两个封隔器元件（37；69）中的另一者位于所述流体端口（214；634）的相对侧，其中，所述环空（92；94）与所述固定部（2；6）的流体端口（214；634）流体连通。
摘要（英）：

A device for a valve comprising a fixed part (2; 6) provided with at least one fluid port (214; 634) and a rotatable sleeve (3; 7) provided with at least one bore (33; 72), wherein: the sleeve (3; 7) is structured in a manner allowing it to rotate the bore (33; 72) inline with the fluid port (214; 634) in order to allow a fluid to flow through the fluid port (214; 634) and the bore (33; 72) when the sleeve (3; 7) is in an open position; the sleeve (3; 7) is structured in a manner allowing it to rotate the bore (33; 72) away from the fluid port (214; 634) in order not to allow a fluid to flow through the fluid port (214; 634) when the sleeve (3; 7) is in a closed position; the fixed part (2; 6) and the sleeve (3; 7) form an annulus (92; 94) between the fixed part (2; 8) and the sleeve (3; 7); and the annulus (92; 94) is restricted axially by two packer elements (37; 69) in the axial directions of the sleeve (3; 7) and the fixed part (2; 6), wherein one of the two packer elements (37; 69) is located at one side of the fluid port (214; 634), and the other of the two packer elements (37; 69) is located at the opposite side of the fluid port (214; 634), and wherein the annulus (92; 94) is in fluid communication with the fluid port (214; 634) of the fixed part (2; 6).
