Claims (6)

1. Предохранительное устройство для систем уплотнения гребного вала судна от наружной воды и от пространства со смазочным средством с многократным уплотнением, которое оснащено со стороны наружной воды по меньшей мере одним обращенным наружу уплотнительным кольцом и со стороны пространства со смазочным средством - по меньшей мере одним обращенным во-внутрь уплотнительным кольцом, причем в каждом случае между двумя соседними уплотнительными кольцами выполнена кольцевая камера, из которых по меньшей мере одна нагружена газообразной средой, в частности сжатым воздухом, с помощью подводящего трубопровода, причем далее давление среды с помощью включенного в подводящий трубопровод органа регулирования давления поддерживается постоянно незначительно ниже, чем давление наружной воды и давление смазочного средства, и причем к нагруженной кольцевой камере подсоединен отводной канал, который сообщен с внутренней частью судна (трюмом) и в который включен регулируемый запорный орган, предпочтительно электромагнитный клапан, который автоматически периодически открывается и закрывается, и причем подача смазочного средства в пространство со смазочным средством осуществляется от установленного на высоте резервуара, статическая высота которого может регулироваться посредством подающего трубопровода для смазочного средства, отличающееся тем, что в подводящий трубопровод (7), ведущий к кольцевой камере (5.2), ниже органа (15) регулирования давления включен второй запорный орган (17), предпочтительно электромагнитный клапан, и ниже него включен воздухонепроницаемый закрытый резервуар (18) с поплавковым выключателем (19), который приводит в действие второй запорный орган (17) таким образом, что при срабатывании поплавкового выключателя (19) закрывается второй запорный орган (17) посредством накопившейся в резервуаре (18) жидкости.1. A safety device for sealing systems of a propeller shaft of a vessel against external water and from a space with a multiple-lubricating lubricant, which is equipped with at least one outward-facing sealing ring on the external water side and at least one facing with a lubricant in the space inwardly with a sealing ring, and in each case an annular chamber is made between two adjacent sealing rings, of which at least one is loaded with a gaseous medium water, in particular with compressed air, by means of a supply pipe, and further, the pressure of the medium by means of a pressure regulating organ included in the supply pipe is kept constant slightly lower than the pressure of the external water and the pressure of the lubricant, and a discharge channel is connected to the loaded annular chamber, which communicated with the inside of the vessel (hold) and into which an adjustable shut-off element is included, preferably an electromagnetic valve that automatically opens periodically and it breaks off, and moreover, the supply of lubricant to the space with the lubricant is carried out from a tank installed at a height, the static height of which can be adjusted by means of a supply pipe for a lubricant, characterized in that in the supply pipe (7) leading to the annular chamber (5.2), below the pressure regulating member (15), a second shutoff member (17), preferably a solenoid valve, is included, and below it is an airtight closed reservoir (18) with a float switch ( 19), which actuates the second locking element (17) in such a way that when the float switch (19) is activated, the second locking element (17) closes by means of the liquid that has accumulated in the tank (18). 2. Предохранительное устройство по п. 1, отличающееся тем, что в подводящий трубопровод (7) между органом (15) регулирования давления и источником (12) давления включены отделитель (14) конденсата и редукционный клапан (13). 2. A safety device according to claim 1, characterized in that a condensate separator (14) and a pressure reducing valve (13) are included in the supply pipe (7) between the pressure regulating body (15) and the pressure source (12). 3.
