    • A power and signal distribution system comprises a converter unit connected to a plurality of control units. The converter unit and the control units are arranged in areas difficult to access, for instance on the sea bed. The converter unit is connected to a remote monitoring and supplying device via at least one cable connection. Each control unit has assigned thereto at least one production apparatus for crude oil or natural gas corresponding gate valves, chokes, biops, actuators. In some embodiments, the power and signal distribution system the converter unit comprises a data separation device and a voltage converter. The converted voltage from the voltage converter is transmitted together with data/signals from the converter unit to at least one of the control units.
    • 电力和信号分配系统包括连接到多个控制单元的转换器单元。 转换器单元和控制单元布置在难以接近的区域中,例如在海床上。 转换器单元通过至少一个电缆连接连接到远程监控和供应设备。 每个控制单元已经分配了至少一个用于原油或天然气的对应闸阀,扼流器,活塞,致动器的生产设备。 在一些实施例中,功率和信号分配系统,转换器单元包括数据分离装置和电压转换器。 来自电压转换器的转换电压与来自转换器单元的数据/信号一起发送到至少一个控制单元。

    • A valve control device (1), in particular for control pods or similar equipment used in the mining and/or production of mineral oil / natural gas, comprises a valve housing (2), in which hole or boring sections (3, 4, 5, 6) are arranged, and a valve slide (7) movable relative to the hole sections, with at least a first and a second flow hole (8, 9) for the alternative connection of a feed line (10) from a fluid pressure hose with at least one actuator (11) or of the actuator to a return line (12) for leading the fluid away, wherein in each case one of the connections is made and the other is interrupted. To improve such a valve control device in that with only slight and economical constructional modifications with retention of all the advantages of known valve control devices, a substantial reduction in the leakage flow is facilitated or even almost completely suppressed, at least first and second valve elements (16, 17), which in the closed position (15) can be pressed onto a valve seat (13, 14) formed especially at a hole section (4, 6), are laterally assigned to the flow holes (8, 9), wherein in the connection position of the first flow hole (8) the second valve element (17) is in the closed position (15) and in the connecting position of the second flow hole (9) the first valve element (17) is in the closed position (15) each pressed onto the respective assigned valve seat (13, 14) in its closed position (15).
    • 特别是用于矿物油/天然气开采和/或生产中的控制舱或类似设备的阀门控制装置(1)包括阀壳体(2),其中孔或钻孔段(3,4) (6,6),以及可滑动地连接至所述孔部分的阀滑动件(7),至少具有第一和第二流动孔(8,9),用于将流体(10)与流体 具有至少一个致动器(11)或致动器的压力软管到用于引导流体离开的返回管线(12),其中在每种情况下,形成一个连接并且另一个被中断。 为了改进这种阀门控制装置,其中只有轻微和经济的结构变化,同时保持已知的阀门控制装置的所有优点,便于或甚至几乎完全抑制泄漏流的显着减少,至少第一和第二阀元件 (16,17),其在关闭位置(15)可以被压到特别在孔部分(4,6)上形成的阀座(13,14)上,横向分配给流动孔(8,9) 其特征在于,在所述第一流通孔(8)的连接位置,所述第二阀体(17)处于所述关闭位置(15),在所述第二流通孔(9)的连接位置,所述第一阀体 在关闭位置(15)中,每个按压在相应的分配的阀座(13,14)处于其关闭位置(15)。
