Abstract
A switching device for optionally passing a flow of medium, such as a highly pressurized gas, through a first or second treatment member (2, 3), in which the medium is subjected to a treatment, such as filtration, heating, cooling or the like, comprises a medium inlet, a medium outlet and two distribution valves (1, 5), of which the valve bodies, which are provided with passages, are attached to a common rotation pin (10). For safety's sake, safety valves (12, 13, 14, 15) are arranged in the connections between distribution valves arranged at the inlet and at the oulet and the two treatment members.
Claims3
Switching device for optionally passing a flow of medium, for example a highly pressurized gas, through a first or second treatment member, in which the said medium is subjected to a treatment, such as filtration, heating, cooling or the like, comprising:
- a medium inlet, a medium outlet and two distribution valves (1, 5), of which the valve bodies, which are provided with passages, are attached to a common rotation pin (10), all tis in such a manner that, in one limit position of the said rotation pin (10), the inlet and the outlet of the switching device are connected to the first treatment member (2), and in the other limit position of the said rotation pin, the inlet and the outlet of the switching device are connected to the second treatment member (3), and
- safety valves (12, 13, 14, 15) arranged in the connections between the distribution valves (1, 5) and the two treatment members (2, 3),
- characterized in that the valve bodies of the two safety valves (12, 14) in the connections (6, 8) between the distribution valves (1, 5) connected to the inlet and outlet and the first treatment member (2) are arranged on a common rotation pin (16), and the valve bodies of the two safety valves (13, 15) in the connections (7, 9) between the distribution valves (1, 5) connected to the inlet a outlet and the second treatment member (3) are likewise arranged on a common rotation pin (17).
