Description

The invention relates to devices for storing cryogenic liquids.

By main auto No. 7787771, there is known a device for discharging live gas from low pressure tanks, containing a drain and a receiving tank, a pressure source connected to a receiving tank, the drain tank is provided with an installed high pressure tank with a check valve, and the tank is connected by valves to the receiving tank, pressure source and _<5 atmosphere [Ί].

The disadvantage of this device is the low productivity due to discrete delivery of fluid. Break issuing szhizhenno- ₂ θ of gas due to the necessity of filling the container.

The purpose of the invention is to increase productivity.

This goal is achieved by the fact that $ _{2 is} that in the device for discharging liquefied gas from low pressure tanks, the high pressure tank is provided with a partition to form an additional tank connected through a non-return valve to the drain tank and through valves with a receiving tank, pressure source and atmosphere.

The drawing shows a diagram of the proposed device. ³⁵

A device for discharging liquefied gas from low pressure tanks contains a drain tank 1, a receiving tank 2, a pressure source 3 connected to a receiving tank ⁴⁰ via a valve 4. The drain tank 1 is equipped with a main 5 and an additional 6 high pressure tanks installed inside it, each soe- dinena ⁴⁵ through the check valve 7 with a drain tank 1 and for engines through 8 and 9, 10 and 11, 12 and 13 respectively with the receiving vessel 2, the source 3 and the atmosphere pressure. Capacities 5 and 6 are separated by a partition 14.

The device operates as follows.

Before starting work, the drain tank 1 and the high-pressure tanks 5 and 6 are filled with liquefied gas, which is also supplied to the pressure source 3. When issuing liquefied gas to the receiving tank 2, the gas obtained in the pressure source 3 is supplied through the valve 10 to the high-pressure vessel 5, the valve 8 must be open and the valve 12 closed. Under the action of liquid pressure, the check valve 7 of the vessel 5 closes and the liquefied gas through the valve 8 is pressed into the receiving tank 2, while a part of the liquefied gas enters the pressure source 3 through the open valve 4.

After emptying the high-pressure vessel 5, the charge gas is switched to the vessel 6 by closing and opening the corresponding valves.

At the same time, liquefied gas from the drain tank 1 begins to flow into the empty container 5 through the check valve 7. At the same time, the valve 12 of the empty container 5 should be open.

After filling the empty high-pressure tank and simultaneously emptying the filled tank, the process of issuing liquefied gas is repeated.

Thus, the proposed device has twice as much productivity for liquefied gas by ensuring its continuous delivery to the receiving tank, for example to a railway or automobile tank. Thanks to this, simple tanks are halved.
