Claims (1)

[Claims for Utility Model Registration] (1) A liquid sealing tank having a sealing liquid reservoir for a non-flammable liquid and an air pipe whose one end is open to the atmosphere and the other end is immersed in the sealing liquid reservoir, and the liquid seal A connecting pipe is connected to the side of the tank and guides the overflow liquid in the liquid sealing tank into the container when the inside of the container containing gas is below a set negative pressure, and a seal part with a nonflammable liquid is provided in the middle. One end of the tube is inserted into the side of the air pipe that is immersed in the sealing liquid reservoir and opens, and when the inside of the container is at a positive pressure set value or higher, the overflow liquid in the liquid sealing tank is guided into the container. A liquid ring type atmospheric valve characterized by being equipped with an overflow pipe. (2) The product of the area where the liquid in the sealing liquid reservoir is in contact with the atmosphere and the liquid level difference from the standard level of the liquid in contact with the atmosphere when the inside of the container is at the set negative pressure is the product of the area where the liquid in the sealing liquid reservoir is in contact with the atmosphere. 2. The area of the liquid in contact with the gas is equal to the product of the liquid level difference from a reference level of the liquid in contact with the gas when the container is at a set negative pressure. Liquid ring type atmospheric valve. (3) A liquid sealing tank having a sealed liquid reservoir of non-flammable liquid and a cap whose lower part is immersed in the liquid sealing liquid reservoir and laid down, the upper part of which is open to the atmosphere, and a liquid sealing tank with one end inside the cap. is inserted, and the other end is connected to a container containing gas, and a connecting pipe is inserted to guide the overflow liquid in the liquid sealing tank into the container when the inside of the container is below a set negative pressure, and a non-flammable pipe is inserted in the middle. an overflow pipe provided with a liquid sealing part and connected at one end to a side surface of the liquid sealing tank to guide overflow liquid in the liquid sealing tank into the container when the pressure inside the container is higher than a set positive pressure; A liquid ring type atmospheric valve characterized by: (4) The product of the area where the liquid in the sealing liquid reservoir is in contact with the atmosphere and the liquid level difference from the reference level of the liquid in contact with the atmosphere when the inside of the container is at the set positive pressure is the product of the area where the liquid in the sealing liquid reservoir is in contact with the atmosphere. 4. The area of the liquid in contact with the gas is equal to the product of the liquid level difference from a reference level of the liquid in contact with the gas when the container is at a set positive pressure. Liquid ring type atmospheric valve.
