Field of the Invention The present invention relates to a flange connection structure of a selection valve, and more particularly, to an improvement in the flange connection structure of a selection valve provided in a fire extinguishing line by improving the area and size of a building. The fire extinguishing gas container, which is discriminatively installed by the gas, ie, the selection valve selectively fastened by the gas pressure is configured as one to enable general-purpose use and interchangeable use, thereby improving workability and rupture of the selection valve. The present invention relates to a flange connection structure of a selection valve capable of preventing a gas accident caused by a gas.

Is provided at the branch portion.

By the angular displacement of the operation element by the operation, the stopper holding the upper surface of the plunger is released, and at this time, the plunger maintains the standby state of the ascent operation. In addition, a screw portion having a fixed length is formed at a lower portion of the selection valve, and this is formed by screwing a flange having a fixed thickness having a number of connecting holes formed at equal intervals on an upper outer surface. It is fastened in a form that is bolted to a flange formed in the conduit.

The selection valve, which is divided into S type and to which the flange is connected, must be fastened similarly to the gas pressure capacity described above.

る。In discriminating the capacities of the selection valve and the flange, the outer shape and the structure of the selection valve are the same, and the size thereof is the same.
Since the length of the screw portion formed at the lower portion of the selection valve and the thickness of the flange connected thereto are different from each other, a great deal of care must be taken during the work in the field.

ならず気密維持性にも問題が発生する。For example, when a gas line having a high gas pressure and a gas valve having a low gas pressure, that is, a flange having a small thickness are erroneously coupled to a selection valve, the flange is fastened to the end of the thread portion of the selection valve. Since the connection is made in an unstable state where the connection is not performed, there is a possibility that the fastening force of the joining portion is reduced and the connection is ruptured due to the pressure of the supplied gas. If the above-mentioned flange whose capacity does not match is completely fastened to the end of the threaded portion, the long threaded portion will penetrate to the lower part of the flange and will protrude, so fastening with the flange formed in the pipeline If this is neglected and fastening is performed with the flange of the pipe, not only the problem of the decrease in the fastening force of the joint but also the problem of maintaining the airtightness will occur.

る。On the other hand, when a relatively high-pressure flange is connected to a relatively low-pressure gas line and a threaded portion of the selection valve by fastening the threaded portion, the length of the threaded portion is short. This causes an unstable coupling state in which the portion does not reach the thread portion of the flange, and there is also a problem that the selection valve may be ruptured due to a decrease in the fastening force of the joint.

The flanges are standardized for high pressure and low pressure, and when the gas pressure is small, it can be made possible by fitting and connecting the gap adjusting ring. As shown in FIGS. 1 and 2 attached to the present invention, a flange connecting screw portion 2 is formed at a lower portion of a selection valve 1, and a flange 3 is fastened to the screw portion 2 to form a flange of a pipe line. 4, the screw portion 2 of the selection valve 1 is formed to be long so as to be able to accommodate a high-pressure gas regardless of the gas pressure, and the thickness of the flange 3 is increased. It is standardized to those for pressure and low pressure, respectively, and the threaded portion 2 is formed by selectively coupling a gap adjusting ring 5 according to the magnitude of gas pressure.

In the figure, reference numeral 21 denotes a hooked jaw formed at the upper end of the screw portion 2 of the selection valve 1. The configuration of the embodiment of the present invention is as described above. The operation of the present invention having such a structure will be described as follows. First, in the case of manufacturing the same, the length of the screw portion 2 formed at the lower portion of the selection valve 1 is made longer and standardized so that a large gas pressure can be accommodated. Since it is only necessary to manufacture and manufacture on a production line, the production line of the selection valve 1 which had to be provided twice in the past can be reduced to one, thereby greatly improving workability and productivity. Can be.

路に設置することができる（図１参照）。In addition, the above-mentioned gap adjusting ring 5 has a sufficient thickness for the remaining margin for the case where the above-mentioned selection valve 1 is connected to the flange 4 formed in the conduit of low gas pressure. Mass production, and each of the flanges 3 already standardized may be separately packaged.
The present invention provides an advantage that the labor required for the packaging operation is reduced by half as compared with the conventional one. When such a structure is installed in a pipeline, when it is installed in a pipeline having a large pressure, the spacing adjustment ring 5 may be removed from the packaging case, and the fastening and installation may be performed in the same order as the normal selection valve 1 installation work. Therefore, the selection valve 1 can be installed in the pipeline without any fear of misconnection (see FIG. 1).

である。On the other hand, when it is provided in a conduit with a low gas pressure, an interval adjusting ring 5 is first fitted into the threaded portion 2 of the selection valve 1 and the upper jaw 2 of the threaded portion 2 is fitted.
1 to prevent further elevation, and in this state, the above-mentioned flange 3 is screwed and then connected to the flange 4 of the pipeline. There is no danger that the screw portion 2 will penetrate and protrude to the lower portion of the flange 3, and the fastening operation is simple.

ようになる。According to the above-mentioned structure of the present invention, the operator combines the above-mentioned combination of the selection valves 1 which has been packed and transferred in one packaging case at the work site into a pipe line thereof, that is, a gas having a large gas pressure. Since the spacing adjustment ring 5 is set in such a manner as to be selected and combined by dividing only the small ones, the possibility of erroneous combination is reduced by half. Of course, there is a possibility that an inexperienced operator may tighten the gas pressure without distinguishing between large and small gas pressures. However, even if the gas pressure is erroneously coupled, without having to repurchase or replace the selection valve 1 itself, This can be easily disassembled on site and the spacing adjustment ring 5 can be removed or fitted and reassembled, greatly improving the convenience and workability of the installation work.
