Abstract (en)

[origin: WO2017184050A1] Pressure reduction valve for a device for degassing certain compounds in liquid mixtures having low boiling points in closed liquid systems, wherein a subpart of the liquid is separated for degassing and wherein degassed liquid is restored to the closed system, wherein the pressure reduction valve is arranged to be located on a conduit in which the said subpart is arranged to flow. The invention is characterised in that the pressure reduction valve comprises a house (31;32) with an inlet (11;21) and an outlet (16;26) for the separated liquid, in that the pressure reduction valve comprises a piston (12;22) which is movable in the said house, which piston is arranged to, to a larger or smaller extent, throttle the supply of the liquid separated to the pressure reduction valve, in that a pump is connected downstream of the pressure reduction valve, in that a compression spring (14;24) is arranged to act between one end wall (17;27) of the piston (12;22) and the house, in that a channel (13;23) is arranged through the piston, which channel connects the inlet (11;21) / outlet (16;26) of the pressure reduction valve to the side of the piston (12;22) facing towards the said spring (14;24), and in that the piston is sealed in relation to the inside of the house (31;32).
