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

A kind of pressure drainage system

Technical field

The present invention relates to Laboratory Instruments apparatus field is and in particular to a kind of pressure drainage system.

Background technology

In school, during chemistry and biotic experiment, need the aqueous solution using distilled water or other configurations, but contain The model for 50 kilograms or bigger that the bucket capacity of the aqueous solution of dress distilled water or configuration has, outlet is located at the bottom of bucket Portion, because outlet long period of soaking is in water, the seam crossing of outlet and water drum can be led because of corrosion or sealing ring is aging and leak Cause too early the scrapping of whole bucket, cause unnecessary waste.

Content of the invention

In view of the deficiencies in the prior art, the present invention a set of solution of proposition, provide a kind of pressure drainage system.

Technical scheme is as follows：

A kind of pressure drainage system, including drainage tube, bucket, piston mechanism composition, one end of described drainage tube is located in bucket Bottom, the other end pass through bucket top outlet below less than the water place horizontal plane in bucket draw, described piston machine Structure is installed on the drainage tube outside bucket, and one end of piston mechanism is provided with the inlet and outlet being respectively provided with check valve.

A kind of pressure drainage system, the outlet of described drainage tube is equipped with valve.

A kind of pressure drainage system, the piston base of described piston mechanism is also equipped with spring, and one end of piston rod is equipped with handss ?.

Beneficial effects of the present invention：

Be applied to fill the bucket water intaking of distilled water using air pressure and siphon principle, structure is simple, eliminate outlet because of corrosion or Sealing ring is aging and the hidden danger of leak.

Specific embodiment

The invention will be further described with reference to the accompanying drawings and examples.

A kind of pressure drainage system, forms including drainage tube 2, bucket 3, piston mechanism 4, and one end of drain 2 pipe is located at water Bottom in bucket 3, the other end passes through the outlet on bucket 3 top to draw below less than the water place horizontal plane in bucket 3, piston Mechanism 4 is installed on the drainage tube 2 outside bucket, and one end of piston mechanism 4 is provided with inlet and outlet, and import, outlet fill respectively There is a check valve 46, equipped with spring 45, one end of piston rod 42 is equipped with handling 41 for the bottom of piston 43.

First open the valve 1 in drainage tube 2 exit, when pressure handles 41, the import of piston mechanism 4 under pressure The check valve 46 at place is closed, and the check valve 46 in the exit of piston mechanism 4 is opened, the air in piston cylinder 44 and drainage tube 2 Discharge from the valve 1 in drainage tube 2 exit；Unclamp when handling 41, act on lower piston 43 return in spring 45, the going out of piston mechanism Check valve 46 at mouthful is closed, and the check valve 46 of the entrance of piston mechanism is opened, and the water in bucket 3 enters work by drainage tube 2 Plug mechanism 4, so repeated multiple times, until current are independently flowed out by valve 1, now can close valve 1, need during water intaking more later Open valve 1, current can independently be flowed out by siphonage.
