Abstract

The utility model discloses a kind of cryogenic liquid vertical storage tank liquid in-out tubular construction, comprise frame, be arranged on the inner container in frame and be connected to the liquid inlet and outlet pipe on inner container, it is characterized in that, the first part bus along inner container end socket of liquid inlet and outlet pipe, to downward-extension, is then back bent into semicircle, and take advantage of a situation and up extend, back bending is tilted toward downward-extension again, and the last end socket along inner container is to downward-extension, final curved to going out frame.The utility model has effectively increased length and the pliability of liquid inlet and outlet pipes, has slowed down the stress that expands with heat and contract with cold and produce, and has the advantages that to reduce heat transmission and cryogenic liquide evaporating capacity.

Description

A kind of cryogenic liquid vertical storage tank liquid in-out tubular construction

Technical field

The utility model relates to the structure on a kind of cryogenic liquid vertical storage tank, relates in particular to a kind of cryogenic liquid vertical storage tank liquid in-out tubular construction.

Background technique

At present, the liquid in-out tubular construction of domestic cryogenic liquid vertical storage tank is all that the head of liquid inlet and outlet pipe and the bottom bulkhead of inner container are connected, and then directly extends downward out frame.Its deficiency is: liquid inlet and outlet tubular construction is too simple, flexible poor, and liquid inlet and outlet pipe is short, sealing gland weak effect, and heat transference efficiency is high, and the phenomenon that causes gasifying is serious.

Publication number is CN202613040 U, and the Chinese patent in open day on December 19th, 2012 discloses a kind of low-temperature storage tank with dissection, and the liquid inlet and outlet pipe surrounding between its inner container and frame has pearlife and vacuumizes.Its deficiency is: liquid inlet and outlet tubular construction is simple, flexible poor, sealing gland weak effect.

Model utility content

The purpose of this utility model is: a kind of length and pliability that increases liquid inlet and outlet pipe is provided, can slows down the stress that expands with heat and contract with cold and produce, and can reduce heat transmission, reduce the cryogenic liquid vertical storage tank liquid in-out tubular construction of cryogenic liquide evaporating capacity.

Technical solution adopted in the utility model is:

A kind of cryogenic liquid vertical storage tank liquid in-out tubular construction, comprise frame, be arranged on the inner container in frame and be connected to the liquid inlet and outlet pipe on inner container, wherein the first part bus along inner container end socket of liquid inlet and outlet pipe is to downward-extension, then be back bent into semicircle, and take advantage of a situation and up extend, then back bending is tilted toward downward-extension, the last end socket along inner container is to downward-extension, final curved to going out frame.

The beneficial effects of the utility model are:

1, increase by one section of circular arc and angle upwards, effectively increased length and pliability into and out of pipe, slowed down the stress that pipeline expands with heat and contract with cold.

2, upwards extension and bending part can form well sealing gland in the time stopping feed liquor and fluid, reduce the transmission of heat, reduce the amount of vaporization of cryogenic liquide.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model;

Wherein, 1-liquid inlet pipe 2-drain pipe 3-inner container 4 framies

Embodiment

As shown in Figure 1, a kind of cryogenic liquid vertical storage tank liquid in-out tubular construction, comprise frame 4, be arranged on the inner container 3 in frame 4 and be connected to the liquid inlet and outlet pipe on inner container 3, the first part bus along inner container 3 end sockets of liquid inlet pipe 1 and drain pipe 2, to downward-extension, is then back bent into semicircle, and take advantage of a situation and up extend, back bending is tilted toward downward-extension again, and the last end socket along inner container is to downward-extension, final curved to going out frame 4.

Claims

1. a cryogenic liquid vertical storage tank liquid in-out tubular construction, comprise frame, be arranged on the inner container in frame and be connected to the liquid inlet and outlet pipe on inner container, it is characterized in that, the first part bus along inner container end socket of liquid inlet and outlet pipe, to downward-extension, is then back bent into semicircle, and take advantage of a situation and up extend, back bending is tilted toward downward-extension again, and the last end socket along inner container is to downward-extension, final curved to going out frame.
