SU458728A1 - Device for detecting leakage of fluid from a tank - Google Patents

Description

one

This invention relates to the field of leak testing products.

A device is known for determining the leakage of liquid from a container, in which there is also a gas under pressure, containing a thermal bottle, a liquid immersed container, a differential pressure gauge, which is generally two gas lines with a thermal bubble and a container installed on the two-way main lines. valve.

The purpose of the invention is to improve the measurement accuracy.

This is achieved by the fact that the device is equipped with a liquid line to communicate the bulb to the tank included in the gas line connecting the pressure gauge to the tank, an additional thermoelectric bottle: M immersed in the tank liquid and communicated with it, and a compensator for gas leakage from the tank .

The drawing shows a diagram of the proposed device.

The device contains thermal containers 2 and 3 immersed in the liquid of the test container 1, of which the thermal bottle 2. is associated with the capacity of 1. directly, and thermd. bottle 3 is the liquid-line 4 with valve 5.

Thermo balloons are interconnected between themselves and the tested capacity by gas gas mains 6 and 7 with a two-position valve 8 and differential meter 9 installed on them. A gas leakage compensator 10 is also connected to the gas line 7 with a valve 11 and a pelvic line 12.

Before testing the tank 1, equalize the gas pressure in the tank 1 and thermo-balloons 2 and 3 with the help of valves 8 and 11 and the level of liquid B using them with valve 5. Then valves 5, 8, 11 are closed. When lowering

the fluid level in the tank 1 decreases the fluid level also in the balloon 2, and the reading of the differential pressure gauge 9 indicates the leakage of the fluid. With simultaneous gas leakage from the tank 1, a drop occurs

gas pressure in the tank 1 and the thermal bottle 2, which is eliminated by means of a gas leakage compensator 10 by blowing gas into the container through line 12.
