Technical Field

The invention relates to the technical field of valves, in particular to a split-phase solution discharge valve for producing 4-methylthiazole-5-formaldehyde.

Background

After condensation reaction and neutralization reaction in the production process of 4-methylthiazole-5-formaldehyde, layered solutions can appear in a reaction kettle, and the two solutions need to be respectively discharged to different procedures for processing on the next step, however, the two phases are easy to be separated unevenly when being discharged, or a valve can not be closed in time when the lower solution is discharged to discharge some upper solutions, or the lower solution is discharged insufficiently, so that a part of the upper solution can be remained when the upper solution is discharged.

The Chinese patent with publication number CN106641367A discloses an oil-water separation float valve, which is characterized by comprising a base, an oil guide cylinder body arranged in the base and a float floatably arranged in the oil guide cylinder body, wherein the top of the oil guide cylinder body is provided with an oil outlet, the bottom of the oil guide cylinder body is provided with an oil suction port, and the oil outlet is connected with the inlet end of an oil guide pipe; the floater floats up and down in the buoyancy change process of the water and the oil, the floater is supported by the buoyancy of the water, the inlet end of the oil guide pipe is closed by the floater, the floater falls down due to the insufficient buoyancy of the oil, and the inlet end of the oil guide pipe is opened to absorb the oil.

However, the invention has the following disadvantages in use: the valve in the patent controls the switch of the invention by floating the floating ball up and down through different oil-water buoyancy, but the buoyancy of the two-phase solution to the floating ball is different in time, but the density difference between the two-phase solution is not too large generally, and the floating ball needs to be between the two solutions, so that the floating speed and the sinking speed of the floating ball in the two-phase solution are not too high, and the valve cannot be closed in time when the two-phase solution is separated, and therefore, the two-phase solution cannot be completely separated.
