Invention Description (i) [Field of Invention] • The present invention relates to a liquid quantitative filling device, especially a type that uses the length and caliber of an inner tube Cooperate to achieve a liquid quantitative filling device that reduces the error in filling capacity, simplifies the operation of adjusting the filling capacity, and can complete a fully automated filling procedure. [Field of Known Technology] According to the liquid quantitative filling device currently on the market, it generally has a liquid tank for containing liquid, and the liquid is replenished to the liquid tank above the liquid tank by gravity, and the liquid tank is provided with A hollow air vent tube is fixed by the fastening part. A three-way valve is installed below the liquid tank. The three-way valve is connected to the liquid tank in the vertical direction and to the upper liquid tank in the horizontal direction. Connected pipelines and liquid discharge pipelines. The liquid discharge pipeline 俾 injects the outflowing liquid into the dispensing container. 0 When you want to perform the process of filling the liquid, you must first manually adjust the height position of the breather pipe to switch the three-way valve. When the field tank is required to flow the liquid through the pipeline to the 'liquid tank' and the height of the liquid flowing into the liquid tank exceeds the bottom end of the vent tube, the vent tube will stop exhausting the air in the liquid tank. At this time, the two-way valve makes the liquid Flow from the liquid tank to the liquid discharge pipe, > Tian Jichu = Ba Zhuang ~ The liquid discharge pipe flows a stack of liquid into the dispensing container to complete the filling operation. -However, the general repacking container can be filled with liquid capacity, such as Shi, QC, 500 CC and 1000 CC, etc., so when the filling operation is performed, + is 250 for repacking container with different capacity, you must readjust the ventilation tube :: In addition, it is difficult to fix the height of the ventilation tube only by the stopper between the ventilation tube and the liquid tank.
