The invention discloses an automatic gas-liquid
separation method, which belongs to the technical field of gas-liquid separation, and is characterized by comprising the following steps that S1, pressurized liquid-containing sample gas is introduced into an interlayer; S2, the
liquid phase is discharged from a liquid outlet in the bottom of the outer cylinder through a circular through hole; S3, in the process that the
liquid phase is discharged from the liquid outlet, the
buoyancy of the stainless steel
buoy is reduced along with reduction of the
liquid phase, a round through hole in the organic
silica gel sealing head is blocked by a spherical plug, and linear sealing is recovered; and S4, the liquid phase stops being continuously discharged from the liquid outlet, so that the liquid phase is always kept in the cylinder bottom space, the
gas phase is prevented from flowing out from the liquid outlet, and automatic gas-liquid separation is realized. According to the
separation method, when the liquid phase is not completely discharged, linear sealing of the stainless steel
buoy can be recovered, the liquid phase exists in the bottom space of the
buoy all the time, and therefore automatic gas-liquid separation is achieved, the separation effect is guaranteed, the separation efficiency is improved, the method is suitable for being used in anti-explosion and poisonous and harmful production fields, and the applicability is enhanced.
