Description of the invention (3) When the safety nut is removed, the above-mentioned sealing tape is damaged, and the sealing effect cannot be obtained. As the safety plate is corroded, a jet error occurs under low pressure. Because the ejection is caused by the multiple ejection openings of the safety nut, it is likely to cause harm to operators and the like who are beside the liquefied gas container. Here, another object of the present invention is to reduce the risk of gas ejection in response to a destructive safety device. Furthermore, a plastic cap body is provided at the filling port or gas release port of the liquefied gas container to prevent foreign matter from entering the piping when these are not in use. This cap system is provided with a thread on the inner surface and is screwed onto a thread provided on the outer surface of the filling or releasing port. After the operator has filled the low-temperature liquid or used the gas in the container, the operator attaches the cap body to the above-mentioned filling port or gas outlet. However, after filling the low-temperature liquid or using the gas in the container, this part The portion will become low temperature, and the operator must bring thick gloves to work, making the screwing of the cap body extremely difficult. In addition, the cap body is mounted on the container by using a stainless steel chain. When the chain is wound around the cap body, it is almost impossible to install the cap body with gloves. Furthermore, because the cap body is made of plastic, it will easily be damaged with impact. Even if the cap body is attached to the container, it is almost impossible to use. Here, another object of the present invention is to provide a cap body which can be relatively easily attached to and detached from a gas filling port or a gas releasing port and is not easily damaged. [Invention] The present invention is a liquid level gauge for the above-mentioned liquefied gas container, which is not directly installed 1240056. V. Description of the invention (4;) on the top component of the container, but through a stainless steel connection with a low heat transfer rate. With this structure, the level gauge will not be excessively cooled, and it will not be easy to produce bad conditions such as cracks in the tube. Furthermore, the floating stop shaft is divided into a plurality of numbers and a ring provided at the end is used. Connections that engage with each other to bend each other. Therefore, because the floating shaft can be tilted without using the connecting part between the rings, even if an excessive external force 5 is applied during use, the floating shaft itself can be prevented from being bent. Also related to the above-mentioned destructive safety device The ejection □ of the safety nut is arranged downward, and a cap body covering the ejection □ is provided on the outside of the ejection outlet. Therefore, the safety plate is blocked from the atmosphere by the cap body to prevent the safety plate from being exposed to the atmosphere The situation of decayed uranium happened. In addition, even if the safety plate is damaged and high pressure gas is ejected from the spout □, the spout P is set to face down 5 so it can maintain the operator ’s near the container: safety 〇 Furthermore, y is installed in the above-mentioned filling port or gas The cap body on the release port is made of rubber. The elastic force is used to force the embedded installation. Because it is not threaded for loading and unloading, it is easy to attach and remove the cap even with thick gloves. Also, because the cap is made of rubber, the strong impact from the outside 5 will not be easily broken.

Fig. 6 is a schematic partial cross-sectional view of the filling port (release port), and a schematic cross-sectional view covering the upper cap body. [Preferred Aspects of Implementing the Invention] In order to explain the present invention in more detail, it will be explained according to the attached drawings. ○ The first diagram is a schematic cross-sectional view of the liquefied gas container of the present invention. This liquefied gas container 1 is housed inside the outer container 2 and supports the inner container 3 with an upper support member 4 and a lower support member. A vacuum insulation space q is formed between the outer container 2 and the inner container 3, and the outer container 3 is covered with a heat insulating material (not shown). The upper support member 4 is composed of a stainless steel tubular short tube, and is welded and fixed to a stainless steel top member and an inner container top provided integrally with the outer container 2. The top member of the outer container 2 is provided with a filling port 10 and a discharge port! i. The liquefied gas introduction liquid flow path branched from the release port 11 is connected to the distribution pipe 12. A plurality of distribution holes 12a, ... are provided in the insertion member in the inner container 3 of the distribution pipe 12. A float 20 of a liquid level gauge L is provided inside the inner container 3. The upper end of the floating stop 20 is provided with a floating stop shaft 21, and the upper end of the floating stop shaft is screwed with the inner guide 23, and the upper end of the inner guide 23 is provided with an inner magnet 25. In the figure, 26 is a gasket. The above-mentioned inner guide 2 at the upper end of the floating shaft 2 3, the inner magnet 2 5 and the like are raised and lowered 1240056. V. Description of the invention (6) It is freely fitted on the hollow portion 30a provided in the core portion 30 of the liquid level gauge L body. . The main body 30 is provided with a hexagonal nut-shaped enlarged diameter portion 31, a tube portion 32, a display tube fitting portion 3 3, and a mounting portion 34 that cuts a thread on the outer surface. A display tube 35 is externally fitted on the outer surface of the tube portion 3 2. The display tube 3 5 is placed on the enlarged diameter portion 31 of the main body 30 in a lower end state, and is fixed to the display tube fitting portion 33 by a forced fitting airtight fitting. Between the inner surface of the display tube 35 and the outer surface of the tube portion 32, there is provided a ring-shaped space portion 36 in a cross-section. Inside this space portion 36, a display ring 40 which can move up and down is housed. This display ring 40 is made of a magnetic body and is attracted by the magnetic force of the inner magnet 25, and moves up and down at the same time as the inner magnet moves. Therefore, by using the vertical position of the display ring 40, the vertical position of the inner magnet can be known. The display tube 35 is made of transparent plastic, and the position of the internal display ring 40 can be observed from the outside. A desiccant 37 is provided in the display inside of the upper end of the tube portion 32. Threads are cut at the inside and outside of the mounting portion 34 provided at the lower end of the body 30, and the inner thread 38 is screwed to the spring mounting jig 42. The spring mounting jig 42 is provided with a flange 42a, and a spring (coil spring) 45 is mounted on the cylindrical portion 42b at the lower end of the flange. A spring stopper jig 46 is fixed to the middle portion of the floating stopper shaft 21 by a socket. Therefore, although the floating stop shaft 21 always keeps downward elasticity due to the spring 45, but because the elastic force is smaller than the buoyancy of the floating stop 20, the floating stop shaft 21 is pressed upwards with the floating stop, so it will proceed with the amount of fluid. Moving up and down. 1240056 V. Description of the invention (7) In addition, the floating shaft 2 1 connected to the upper end of the floating stop 20 is divided into a plurality of pieces (in the example of the figure, the upper member 2 1 a and the lower member 2 1 b are two) At the lower end of the upper member 2 1 a and the lower end of the lower member 2 1 b, connecting rings 2 1 c and 2 1 d are integrally formed, respectively. The two ring systems are freely deflected and engaged with each other and constitute a free connection member. Therefore, the floating shaft 21 can bend freely in this direction in this part. In addition, the lower end of the floating stop shaft 21 is screwed to the floating stop 20. The body 30 of the level gauge L is attached to a stainless steel connector 55 fixed to the top of the outer container 2 by welding or screwing with screws. The figure illustrates an example of this installation method. In this example, the cylindrical connector 5 5 is welded (also screwed) and fixed to the outer container, and the internal thread of the connector is screwed to the body 30.装 部 部 34。 Mounting section 34. The height of the connector 55 is tens of mm, such as about 30 mm. If it is lower than this height, the expected heat transfer prevention effect will not be obtained. On the other hand, if it is too high, it will protrude above the level gauge, which will cause problems in handling. The level gauge L is provided with a sealing material at an appropriate position to maintain airtightness. Next, Fig. 5 shows a destructive safety device s. The destructive safety device S is provided with a body portion 62 at the front end of a stainless steel pipe 61 which is passed through the inner container. A plurality of (three shown) hubs 62a, ... openings 63, ... 'are provided on the body portion 62, and these openings communicate with the inside of the pipe 61 through through holes 64, ..., respectively. Among them, when the pipeline 61 is installed in the inner container 3, the body of the destructive safety device is installed on the downward opening 6 3. The other two openings 63, 63 are respectively equipped with a pressure gauge 80 and a spring-type safety device 81. The destructive female full-body device S is provided with a helmet body 65 provided with a spout 65a. At 1240056 V. Description of the invention (8) The bottom surface of the mounting hole 65b of the helmet body is provided with a destructive safety plate. In this state, because the helmet body 65 is screwed with a screw, the safety plate 67 is pressed with the hat body and the hub 6 2 a of the body. dense. On the discharge opening 65a of the hard hat body, a plastic cap body 69 is conveniently covered with its elasticity and forcedly embedded, and the discharge opening 65a is covered. Doctor 1 This prevents foreign matter from entering the spit 65a. When the safety plate 67 is damaged, the cap body 6 9 will be blown up with the gas emitted. The cap body for a jig is attached as shown in FIG. The cap body 70 is made of non-flammable rubber with a cross-section cup shape, and is not provided with screws like the conventional cap body. When the liquefied gas container is not used, the cap body covers the discharge port 11 or the filling port 10 to prevent foreign matter from entering. Because the filling port or the discharge port is pressed, it can be attached by elastic force, so even when wearing Gloves can also be easily covered. Furthermore, it is not easy to break even if it is impacted or dropped by other objects. In addition, the cap body 70 is connected to a drop preventing chain 71 like a conventional cap body. The chain is attached to a front end of a through hole 70a provided at a central portion of the cap body 70, and is attached to The stop ring 72 is constituted by a structure for preventing the stop ring 72 from falling off. Therefore, it can be completed with a simple structure and a small number of parts. In addition, the symbol 7 5 in the figure refers to the upper filling valve, 7 6 refers to the liquid take-off valve, 77 refers to the release valve, 78 refers to the pressure maintaining valve, pressure regulating valve and economizer to form an integrated LCCM, 82 Refers to the outer container safety valve. The liquefied gas container 1 is installed on the container body because the liquid level gauge L is made of stainless steel -10- 1240056. 5. Description of the invention (9) The connector 5 5 is not easily cooled with the liquefied gas inside the container. It is extremely low temperature, and it is less likely to cause problems such as cracks on the display tube. Furthermore, the floating stop shaft 21 provided on the floating stop 20 of the level gauge L can be bent freely because a free connection member J is provided at the intermediate portion. Therefore, unlike a conventional straight axis, even if a forced force is applied during the retrieval process, the force will escape with the bending of this part, so that the shaft body will not be bent. In addition, the free-connecting member j always maintains an almost straight shape, and conveys the buoyancy of the floating stop 20 and the pressing force of the floating stop shaft 21. Furthermore, the destructive safety device S of the liquefied gas container 1 is installed in such a manner that the gas is sprayed downward when the safety plate 67 is damaged, so that the surrounding workers can also ensure safety. At the same time, the ejection opening of the helmet body 65 is covered by the force-embedded cap body 69, so that the safety plate 67 can be prevented from contacting the atmosphere, making the safety plate less prone to corrosion. Furthermore, the liquefied gas container 1 and the filling port 10 are covered with a rubber cap 70 when not in use, so that no foreign matter can enter. Since the cap body 70 is made of rubber, it is not easy to be damaged by impact, and even if a mounting mechanism such as a thread is specially provided, it can be easily attached and detached with its own elastic force, which is convenient in practice.
