Small-sized vacuum filling device with controllable filling speed

Abstract

The invention discloses a small-sized vacuum filling device with a controllable filling speed. The small-sized vacuum filling device comprises a filling speed control valve, a liquid material container, a two-way control valve, a three-way control valve and an air or liquid conduction pipe. The filling speed control valve is a reducing valve or a needle valve; the upper end of the liquid materialcontainer is provided with a sealed container with two small holes; a liquid material is filled into the container; an air or liquid conduction pipe is inserted into each of two holes and the holes are sealed; one of the two conduction pipes is connected with a four way and the other one is connected with a three-way valve; the air conduction pipe connected with the four way is positioned above the liquid level, and the air conduction pipe connected with the three-way control valve is positioned below the liquid level; one end of the four way is connected with the container, the other three ends of the four way are connected with the reducing valve or the needle valve, a pressure gage, and a two-way valve respectively; one end of the reducing valve or the needle valve is connected with the four way, and the other end of the reducing valve or the needle valve is connected with atmosphere; one end of the two-way valve is connected with one end of the four way and a vacuum extraction pipe; an end 1 of the three-way valve is connected with the liquid material container, an end 2 of the three-way valve is connected with the vacuum extraction pipe and an end 3 of the three-way valve is connected with a workpiece to be filled; and the two-way valve, the three-way valve and the air conduction pipe of the vacuum extraction pipe are connected by a T-shaped air conduction pipe.

Description

technical field [0001] The invention relates to the technical field of vacuum filling, in particular to a vacuum filling for dye-sensitized solar cell electrolyte with a controllable filling speed and a small controllable filling for other vacuum filling liquids that require a controllable filling speed Vacuum filling device with high filling speed. Background technique [0002] Controlling the filling speed in vacuum filling is a very necessary operation control process, which can be widely used in vacuum filling of all liquids. At present, the non-controllable filling speed often used in the filling process, due to the uncontrollability of the negative pressure of the container to be filled when the liquid is sucked in, will bring the following adverse consequences: [0003] (1) Bubbles will be generated when the liquid material is rapidly sprayed into the container to be filled; [0004] (2) The rapid liquid flow will cause a greater impact on the container and the obje...
