When the Ce solution froze, the internal pressure of the KCe tank reached several hundred kg/am K, destroying the surrounding wall of the tank, and when it thawed, the KC1 solution spouted out to the outside. there were. In addition, a pressure reducing valve is often installed near the KCe tank that pressure-feeds the KCg solution to the Senna section, and the pressure reducing valve may malfunction.
Ce Ri. The above-mentioned destruction often occurred due to cracks and scratches occurring in the tank material. At this time, the above-mentioned KCe solution in the tank fragments directly hit the worker, causing harm to the human body. There was also a risk that it could cause harm. The present invention was made in view of such circumstances.
The object is to provide a liquid storage container for an analyzer that is simple in construction, inexpensive to manufacture, and free from the drawbacks and dangers mentioned above.

である◎Hereinafter, the present invention will be explained in detail using figures. 1st
The figure is an explanatory diagram of an example of use when the embodiment of the present invention is used, and in the figure, 1 is a sensor section consisting of, for example, a pH sensor, and 2 is a signal transmission device for receiving a detection signal from the sensor section 1. cable, 4 has a predetermined liquid inside (e.g. xcg solution)
Liquid storage container according to an embodiment of the present invention for storing %41, 42a
caps attached to the upper and lower parts of the container 4, respectively;
43 A pressure gauge is attached to a predetermined position on the upper part of the container 4 to indicate the internal pressure of the container 40. A pressure gauge 44 supplies a predetermined gas through a pressure reducing valve (not shown) or the like to measure the internal pressure of the container 40. 4i is a support column made of, for example, a pipe; 6.61 is a support for supporting the container 4 on the support column 5; and 6 is a support for supporting the liquid in the container 4. sIJ+ with the pipe leading to Senna part 1. This is an enlarged cross-sectional view of the main part of the fourth embodiment of the present invention, showing the vicinity of the main part of the fourth embodiment of the present invention. In the figure, the same symbols as in FIG. Omitted. In the iris diagram 2, 6 is the container 40jll (or side wall),
Reference numeral 9 is a member that is % thinner in the vicinity of the outlet 9'l from which the liquid is drawn out than the other part 9'l of the bottom, and constitutes the bottom of the container 4;
It is a holding member which has a predetermined shape with a groove and is press-fitted to hold down the member 9, and for example, a welded portion 101 is welded and fixed. The present invention is not limited to the configuration shown in the enlarged cross-sectional view of the main part in FIG. Various modifications are possible within the
The member 1 installed on one wall 8 in the figure, the member attached to member 9, and the holding member may all be integrally constructed of the same material. i9. The side I18 is often made of a transparent plastic material such as vinyl chloride resin.The functions of the embodiment of the present invention having the above structure will be explained below. In FIG. 1, the above-mentioned liquid is first sealed in the liquid storage container 4 so that about 80X of the internal volume is the above-mentioned liquid and about 20% of the internal volume is the gas for pressure feeding. Incidentally, when the internal volume is sufficiently filled and the liquid is frozen, the internal pressure of the container 4 reaches about 500 kg/cm2, but if there is a gas layer of about 20% as mentioned above, The internal pressure becomes about one tenth or less. Further, the wall thickness of the peripheral wall 8 of the container 40 and the wall thickness near the outlet 9 of the member 9 are designed to be t and h, respectively, and the safety factor is, for example, 10 and 5, respectively, with respect to the maximum working pressure. If this is done, even if internal pressure is generated in the container 4 that may destroy the surrounding wall, etc., the area near the outlet 91 of the member 9 will be destroyed first, so the surrounding wall of the container 40 will be destroyed first. 8
According to the embodiment of the present invention as described in detail above, the wall thickness of a predetermined portion of the bottom of the liquid storage container can be reduced without increasing the thickness of the liquid storage container. Because of this structure, it has the advantage of a simple structure and low manufacturing cost. Furthermore, even when the pressure inside the liquid storage container rises abnormally, a predetermined portion of the bottom is destroyed first, so there is no concern that the disadvantages and dangers of the conventional example will occur. Furthermore, since the peripheral wall of the liquid storage container is often made of transparent glass material as mentioned above, it has the advantage that the amount of liquid remaining inside can be easily checked visually. Although the KCg tank has been described in detail as an example, the present invention is not limited to this and is suitable for use in various liquid containers for analyzers having similar purposes.
