Claims

[Scope of utility model registration request]

The main body of the device is divided by a partition wall into a first pressure adjustment chamber at the top and a second pressure adjustment chamber at the bottom.
The pressure adjustment chamber and the second pressure adjustment chamber are communicated with each other by a connecting pipe, while a connecting pipe that communicates with a pressure controlled device such as a tank is connected to the upper part of the first pressure adjustment chamber, and one end of the connecting pipe is connected to the atmosphere. A first open pipe, which is open to the atmosphere, is connected to the lower part of the second pressure regulating chamber, a siphon pipe is connected to the lower part of the second pressure regulating chamber, and a second open pipe, one end of which is open to the atmosphere, is connected to the upper part of the second pressure regulating chamber.
An open pipe is connected, the liquid level height in the first pressure regulating chamber is regulated by the amount of protrusion of the communicating pipe from the partition wall, and the liquid level height in the second pressure regulating chamber is equal to the siphon pipe height. regulated by
The control negative pressure is controlled by the immersion depth of the first open pipe into the liquid level of the first pressure adjustment chamber, and the control positive pressure is controlled by the immersion depth of the second open pipe into the liquid level of the second pressure adjustment chamber. A pressure control device characterized by being controlled by.
