There are seal water sealing devices, pressure breaking plates as shown in FIG. 6, etc. The single tube direct water sealing device is a device in which the lower end of the pressure regulating tube 2 connected to the gas transfer tube 1 etc. is opened below the liquid level of the sealing tube 15. The single tube U-seal water seal device is a device in which the lower end of the pressure regulating tube 2 connected to the gas transfer tube 1 etc. is formed into a U shape, and the U-shaped portion is filled with liquid. Devices using pressure rupture plates are
This is a device in which a destruction plate 19 that is destroyed at a predetermined pressure is installed at the other end of a pipe connected to a pressure vessel 17 or the like.

という欠点もある。However, with single-pipe direct water sealing devices and single-pipe U-seal water sealing devices, when the negative pressure inside the gas transfer pipe or gas-containing container becomes abnormally large, water is sucked into the gas transfer pipe, etc. This has drawbacks such as interfering with fan operation. Furthermore, if the positive pressure becomes abnormally large, the water sealing liquid will be blown away, so there is a drawback that the use of the water sealing device must be temporarily suspended. In order to operate accurately in response to pressure fluctuations in gas transfer pipes, etc., it is necessary to maintain a constant amount of seal water, but if the water is operated for a long time, the amount of water decreases due to water evaporation, etc., resulting in inaccurate operation in response to fluctuating pressure. There is also the disadvantage of being

ての作用をすることとなる。The seal liquid in the primary seal pipe flows out into the atmosphere discharge pipe or the secondary seal pipe when the pressure inside the gas transfer pipe or the gas-containing container becomes more positive or negative than a predetermined value,
The gas transfer pipe and the like pass through the primary seal pipe and are exposed to the atmosphere. This can prevent damage to the gas transfer pipe or the like due to abnormal positive or negative pressure. The primary seal pipe is constantly supplied with liquid from the liquid supply pipe, so if the abnormal positive pressure or negative pressure falls below a predetermined value after the destruction prevention device is activated, the primary seal pipe will be filled with liquid. It will be done. As a result, the rupture prevention device automatically acts as a sealing device again.
以下本発明の装置およびその作用を、気体移送管内部の

FIG. 3 is a side view showing the operating state of the apparatus. FIG. 3 is a side view showing the operating state of the apparatus of the present invention when the pressure inside the gas transfer pipe exceeds a predetermined value and becomes an abnormal positive pressure.

常に一定となるようにしている。One end of the pressure regulation pipe 2 connected to the gas transfer pipe 1 is inserted into the secondary seal pipe 3, and a U-shaped primary seal pipe 4 is connected to the upper part of the secondary seal pipe of the pressure regulation pipe 2. has been done. One end of the primary seal pipe 4 is connected to an atmosphere discharge pipe 5 connected to the lower part of the secondary seal pipe 3. A water supply pipe 6 is installed in the primary seal pipe 4. An overflow pipe 7 is provided in the secondary seal pipe 3 so that the level of water inside the secondary seal pipe is always constant.

と等しい。When the pressure inside the gas transfer pipe 1 is negative and it is operating normally, the liquid level 8 inside the pressure adjustment pipe 2 and the overflow surface inside the secondary seal pipe 3 are the same as shown in FIG. The height difference H from 9 is the liquid level 1 on the pressure adjustment pipe side of the U-shaped primary seal pipe 4.
The difference in height between 0 and the liquid level 11 of the atmospheric discharge pipe 5ffll! (
is equal to

吸引される。When the pressure inside the gas transfer pipe 1 becomes an abnormal negative pressure equal to or higher than the predetermined value -82, the seal water in the primary seal pipe flows to the pressure adjustment pipe side, as shown in Fig. 2, and the seal water flows into the secondary seal pipe. The water overflows from the overflow pipe 7. Therefore, the seal provided by the primary seal tube is opened, and air from the atmosphere discharge tube 5 is sucked into the gas transfer tube.

ようにするためである。In this case, the liquid level height Hl from the overflow surface inside the pressure regulating tube
It is necessary to set the value of S so that the relationship S≦Hl is established between the actual height S of the primary seal pipe and the actual height S of the primary seal pipe. This is to allow the water in the primary seal pipe to flow toward the pressure regulating pipe when the negative pressure reaches a predetermined value -I (l).Also, the overflow surface 9 and the primary seal pipe to the pressure regulating pipe It is necessary to set the value of l so that the relationship AI>S is established between the height difference AI with respect to the connecting port 12 and the actual height S of the primary seal pipe. This is to prevent water in the secondary seal pipe from flowing back into the primary seal pipe.

管のシール水を大気放出管側へ流出させるためである。When the pressure inside the gas transfer pipe becomes an abnormal positive pressure equal to or higher than a predetermined value Hh, as shown in Figure 3, the seal water in the primary seal pipe flows to the atmosphere discharge pipe, and the secondary seal pipe overflows. It overflows from the flow tube 7. Therefore, the seal provided by the primary seal tube is opened, and the gas from the gas transfer tube is released into the atmosphere through the atmosphere discharge tube 5. In this case, the relationship S = Hh is established between the difference Hh in the liquid level between the liquid level 8 and the overflow surface 9 inside the pressure regulating tube and the actual height S of the primary seal tube. It is necessary to set the value of S. This is to cause the seal water in the primary seal pipe to flow out to the atmosphere discharge pipe side when the positive pressure reaches a predetermined value +Hh.

破れるのを防止するためである。Also, the height difference Ah between the overflow surface 9 and the lower end of the pressure regulating pipe,
It is necessary to set the value of Ah so that the relationship Ah > Hh is satisfied with Hh. This is to prevent the seal of the secondary seal pipe from breaking when the value is below a predetermined value.
