Description

Technical Field

[0001] The utility model relates to the technical field of gas storage tanks, in particular to a gas storage tank with a pressure monitoring function. Background Art

[0002] A gas tank is a container for storing and transporting gas. In a gas tank, the gas has a certain pressure. As the gas is filled, the pressure inside the gas tank gradually increases. Inside the gas tank, there is a difference in pressure between the top and bottom due to the weight and pressure of the gas. Generally, the pressure at the top of the gas tank is a certain value lower than that at the bottom. This value is related to factors such as the size, design, and type of gas in the gas tank. For large gas tanks, due to uneven gas density and temperature differences, the temperature difference between the upper and lower parts of the gas tank will be more serious, which may cause the tank body to deform, thus affecting the service life and safety of the gas tank. Therefore, a gas tank that can monitor the pressure difference between the top and bottom of the gas tank is needed.

[0032] One side of the differential pressure transmitter 3 is fixedly connected with an external probe 4 and an internal probe 7, and one end of the internal probe 7 is fixedly connected to the lower side of the tank body 1;

[0033] When gas is stored in the tank body 1, the differential pressure transmitter 3 can detect the internal and external pressure difference through the external probe 4 and the internal probe 7, convert the pressure signal into an electrical signal, and then obtain the accurate pressure value of the lower part of the tank body 1;

[0034] The differential pressure transmitter 11 can detect the air pressure in different areas above the differential pressure transmitter 11 through an internal probe 23 that moves up and down on one side.
