Abstract

(57) [Summary] [Issue] Are measuring instruments such as eye-measurement systems and sensors commonly used, and when using them in the dark or when using oils, etc., there are cases of failure, high risk, and improvement points. There were many. In order to eliminate these drawbacks, the present invention is significant in that it utilizes air pressure in the tank to eliminate the conventional drawbacks and achieves the purpose simply and automatically. [Solution] When subdividing the required amount into small containers,
Open the stop valve to allow the liquid in the large container to flow in using the drop.
At the same time, take in air and maintain the pressure and balance in the container,
The feature is that it stops the inflow of air at the liquid level in the small container and controls the outflow of liquid to obtain the target amount.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field to which the Invention belongs] The present invention relates to general liquid metering.

 [Prior Art] Generally by visual inspection. Although it is mainly equipped with an electric sensor, the former is inconvenient for use in the dark and people with visual impairments, and there are many cases of failure.The latter causes fever if used incorrectly when handling oils, etc. However, the risk of explosion, explosion, etc. is high, there are many problems such as the disposal of used batteries, and it is not economically preferable.

 [Problems to be Solved by the Invention] In order to eliminate these drawbacks, the present invention closes the air inlet G with the liquid surface flowing into the container B, and uses the air pressure in the large container A to prevent the liquid from flowing out. At the very least, the aim is to eliminate the drawbacks of conventional instruments and automatically measure the target amount to achieve that purpose.

 [Embodiment] In order to subdivide the liquid in a large container A, which is closed as shown, into small containers B, a flexible outflow pipe C connected to the large container A and an air inflow pipe attached to the flexible outflow pipe C. D and the outlet F at the tip end F When the metering device that integrates the stop valve E that opens and closes the inlet G is inserted into the small container B and the upper part H is pushed down to open the stop valve E, F and G are opened and the large container The liquid in A begins to flow in from G due to the head, the air flows in from D, and the air pressure in the large container is balanced.

 When the amount of liquid in the small container B rises to the position of G, the liquid surface closes the hole of G and obstructs the inflow of air, so that the pressure and balance in the large container become imbalanced and the liquid flow is automatically controlled. The target amount can be easily obtained by closing the holes E and F with the stop valve E and removing them.

 [Effect of the device] Therefore, if the position of the air inlet G is changed up and down, the required amount can be automatically obtained easily even in a dark place, and a safe and economical target can be achieved.

Claims (1)

[Utility model registration claims] 1. An air inflow pipe D provided adjacent to a liquid outflow pipe C is closed by an air inlet G at the liquid level of a small container B, the air pressure in the large container A is used to block the liquid flow, and a stop valve is provided. With E, the liquid outlet F and the air inlet G are closed to automatically measure the amount of liquid.
