Abstract

The utility model discloses a spherical low-temperature liquid storage container, which comprises a liner, a shell, a pressurizing pipe, a pressure detecting pipe and a liquid outlet pipe, wherein a vacuum layer is arranged between the liner and the shell, the pressurizing pipe, the pressure detecting pipe and the liquid outlet pipe pass through the shell to be respectively communicated with corresponding pipe orifices on the liner, the liner is provided with a first pipe orifice which is communicated with the pressurizing pipe, a second pipe orifice which is communicated with the pressure detecting pipe and a third pipe orifice which is communicated with the liquid outlet pipe, both the liner and the shell are a sphere, and the first pipe orifice, the second pipe orifice and the third pipe orifice are arranged in an upper half spherical area of the liner sphere. Due to the adoption of the spherical low-temperature liquid storage container, external force from different directions can be scattered, so the explosion possibility can be reduced, and the safe use can be guaranteed.

Description

A kind of spherical cryogenic liquide reservoir vessel

Technical field

The utility model relates to a kind of reservoir vessel, relates in particular to a kind of spherical cryogenic liquide reservoir vessel.

Background technique

Widely used middle-size and small-size cryogenic liquide reservoir vessel is a vertical type cylinder type structure at present, diameter is little, the build height, the center of gravity height, damping performance is poor, and especially level (radially) vibrations or quilt bump are prone to accident, have problems such as transport performance difference, need vertically lay and use and transport, because reasons in structure is not suitable for using in the special place of frequent vibrations.

In like manner, be designed to the cryogenic liquide reservoir vessel that level (horizontal) is used or transported, when running into vertical vibration and vertical bump, also will cause security incident.

Therefore no matter be traditional cryogenic liquide reservoir vessel of vertical structure or horizontal type structure, all will be shaken and cause life time to shorten, or directly be caused damage, poor to the particular surroundings application adaptability.

And deposit the occasion (as adopting the vehicle of liquid fuel) of flammable liquid at some, if adopt traditional cryogenic liquide reservoir vessel at present, when vibrations that are subjected to level or Vertical direction or bump, the liquid of inner bag cryogenic high pressure very easily seepage enters in the pipeline that connects inner bag, and these pipelines generally are in the environment with respect to inner bag higher temperatures low pressure, seepage entered liquid in the pipeline and will expand rapidly and become gas this moment, and is very easily explosion caused, can't satisfy the requirement of safe handling.

The model utility content

The purpose of this utility model provides a kind of spherical cryogenic liquide reservoir vessel, can disperse all directions external force, reduce the possibility of blast, guarantee safe handling.

The utility model realizes that the technical solution of above-mentioned purpose is: a kind of spherical cryogenic liquide reservoir vessel, comprise inner bag, shell, pressure inlet, the Pressure testing pipe, drain pipe, vacuum-pumping tube, it between described inner bag and the shell vacuum layer, has first mouth of pipe that is communicated with pressure inlet on the described inner bag, second mouth of pipe that is communicated with the Pressure testing pipe, the 3rd mouth of pipe that is communicated with drain pipe, described inner bag and shell are spheroid, described first mouth of pipe, second mouth of pipe and the 3rd mouth of pipe all are arranged on the episphere zone of inner bag spheroid, pressure inlet, the Pressure testing pipe, drain pipe all pass shell respectively with inner bag on the corresponding mouth of pipe be communicated with, infiltrate the chance of overflowing in the pipeline to reduce shell and the inner bag back liquid that is subjected to clashing.

The utility model also comprises the repair and maintenance pipe that is used to maintain, and the episphere of described inner bag spheroid also is provided with the 4th mouth of pipe, and described the 4th mouth of pipe is communicated with the repair and maintenance pipe.

The utility model also comprises and is used for the vacuum-pumping tube that vacuum layer vacuumizes, and described shell is provided with and vacuumizes the mouth of pipe, and the described mouth of pipe that vacuumizes is communicated with vacuum-pumping tube, by vacuum-pumping tube vacuum layer is vacuumized.

Pressure inlet described in the utility model, Pressure testing pipe, drain pipe all are divided into the episphere zone of shell.

Compared with prior art, the utlity model has following advantage:

1. can disperse the external force of all directions, center of gravity is low, withstand voltage height, and damping and conformability are good, can use safely in vibration environment for a long time; Can store LN2, LO2, LPG, LNG, LNG, cryogenic liquides such as LAr are applicable to the air-conditioning of vehicle, the use of the oxygen supply of transportation fresh and living aquatic products and power fuel etc.

2. center of gravity is low, is convenient to install and fix;

3. have the repair and maintenance pipe, can regularly do maintenance, and the mouth of pipe of each pipeline all is arranged on the first half of spherical inner bag, the possibility of minimizing fluid seepage generation blast.
