Abstract

PURPOSE:To prevent breakage of nozzles by a construction wherein the nozzle barrels are suspended from an outer tank and the nozzles are connected to an inner tank through collapsible bellows and accordingly only the bellows will be broken when the inner tank is subjected to fracture. CONSTITUTION:If a liquid stored in a low-temperature tank leaks out into space because of a fracture of a side plate 4 of an inner tank 3, a pressure in the inner tank 3 will decrease, while a pressure in the space increases, resulting in a fracture of a roof plate 6 of the inner tank. If this roof plate 6 is subjected to the fracture, the bellows 23 and 20 will be broken before the nozzels 17 and 18 are broken, thereby protecting the nozzles 17 and 18 from breakage.

) and the outer tank, so in the unlikely event that the inner tank (3) is destroyed and low-temperature liquid leaks into the space (S), the inner tank (3) While the internal pressure decreases, the pressure in the space (S) increases, so external pressure may act on the inner tank roof plate (6) and destroy the inner tank roof plate (6). Even if this inner tank roof plate (6) breaks, it is necessary to support it so that the nozzle itself will not be destroyed.

特徴とするものである。Therefore, the present invention has been devised as a nozzle mounting structure for a low-temperature tank having the structure shown in Fig. 1 in order to prevent the nozzle from being destroyed when the inner tank roof plate is destroyed. A nozzle for injecting and discharging liquid is inserted into the roof of the low-temperature tank which has a cold insulation structure inside the outer tank, and the nozzle is suspended and supported by the roof of the outer tank, and the nozzle is airtightly attached to the roof of the inner tank using a bellows. It is characterized by the fact that it is connected to each other.

A nozzle barrel (x8h) with an opening for penetrating a nozzle αη for liquid injection and a pump nozzle (g) for discharging liquid, and having a foot pulp (18α) at the lower end and high strength as shown in Fig. 3. A pump nozzle (G) for dispensing liquid, which is made by housing an electric pump (i8dl), is inserted into one of the above openings through an electric pump hanging wire (1), and a pump nozzle (G) for dispensing liquid is inserted into the other opening. The pump nozzle (G) is fixed to the outer tank roof plate α→ via the frame θ field provided on the outer tank roof plate Q→, and the entire nozzle is suspended by the outer tank roof plate C14). In addition, the inner tank roof plate (6) and the parrel (1SH) of the pump nozzle (G) are made of bellows that can absorb the thermal expansion and contraction of the inner tank roof plate (6). The pump itself is airtightly connected via a fence, and a support stand ψ is provided on the bottom plate (5) to prevent the pump from hitting the bottom plate (5).
The stopper (18h) is placed on the motor through the stopper ((a)) fixed to the lower end of the no-cooler (18h).
The gap (α) between the upper surface of the support base (e) and the support base (b) is determined in relation to the amount of extension of the bellows itself. In addition, the liquid injection nozzle αη is fixed to the outer tank roof plate 0, as in the case of the pump nozzle (G), and is fixed to the inner tank roof plate (6).
) are connected via bellows.

に行える。The low temperature liquid in the inner tank (3) is sucked into the nozzle nozzle (18h) by the operation of the pump nozzle (to).
Make it more discharged. At this time, the expansion and contraction of the inner tank (3) can be absorbed by the bellows HIn without affecting the nozzle (g) αη, and the nozzle barrel (18b) can also be freely thermally contracted.

次に、万一、内槽（３）の側板（４）が破壊し、貯蔵液

低下し、反面空間（Ｓ）内の圧力が増大する。Next, in the unlikely event that the side plate (4) of the inner tank (3) breaks and the stored liquid leaks into the space (S), the pressure in the inner tank (3) will decrease and, on the other hand, pressure increases.

きる。As a result, the inner tank roof plate (6) turns in half and breaks. When this inner tank roof plate (6) is destroyed, in the present invention, the nozzle (1
7) Since the bellows (C) (1) is designed to break before (G) breaks, the nozzle is prevented from being damaged even if the inner tank roof plate (6) breaks. Can be done.

Even if gas is released inside S), the exterior roof plate α 弔 will be replaced by the inside cold insulation material (
Since the outer tank roof plate 04) is kept cool by the outer tank roof plate 04), the outer tank roof plate 04) does not become cold or suffer brittle fracture.

Since it is configured to communicate via a flexible bellows, even if the inner tank breaks and the liquid flows out, creating a vacuum in the inner tank and causing the inner tank roof to dent, the bellows part will not break and destroy the nozzle. have an effect.
