Problems solved by technology

[0002] In school, distilled water or other configured aqueous solutions need to be used in chemical and biological experiments, but some buckets containing distilled water or configured aqueous solutions have a capacity of 50 kg or more, and the water outlet is located at the bottom of the bucket. If soaked in water for a long time, the seam between the water outlet and the water cylinder will leak due to corrosion or aging of the sealing ring, which will lead to premature scrapping of the entire water bucket, resulting in unnecessary waste

Abstract

The invention relates to the field of laboratory instruments, and discloses a pressure drainage device comprising a drainage pipe, a water barrel and a piston mechanism. One end of the drainage pipe is located at the bottom of the interior of the water barrel, and the other end of the drainage pipe penetrates an outlet in the upper portion of the water barrel and is drawn out below the horizontal plane where water in the water barrel is located. The piston mechanism is installed on the portion, outside the water barrel, of the drainage pipe. One end of the piston mechanism is provided with an inlet and an outlet, wherein check valves are arranged on the inlet and the outlet correspondingly. Gas pressure and the siphon principle are adopted, the pressure drainage device is used for taking water out of the water barrel containing distilled water, the structure is simple, and the potential hazard that because of corrosion or seal ring ageing, a water outlet leaks water is eliminated.

Description

technical field [0001] The invention relates to the field of laboratory instruments and equipment, in particular to a pressure drainage device. Background technique [0002] In school, distilled water or other configured aqueous solutions need to be used in chemical and biological experiments, but some buckets containing distilled water or configured aqueous solutions have a capacity of 50 kg or more, and the water outlet is located at the bottom of the bucket. Soaked in water for a long time, the seam between the water outlet and the water cylinder will leak due to corrosion or aging of the sealing ring, resulting in premature scrapping of the entire water bucket and unnecessary waste. Contents of the invention [0003] In view of the deficiencies in the prior art, the present invention proposes a set of solutions, providing a pressure drainage device. [0004] The technical scheme is as follows: [0005] A pressure drainage device, comprising a drainage tube, a bucket,...
