Description

TECHNICAL FIELD

[0001] The utility model relates to nitrogen balance cylinder technical field more specifically, it is a kind of nitrogen balance cylinder system. BACKGROUND

[0002] The working principle of nitrogen balance cylinder system is based on the compression and expansion characteristics of nitrogen. When the pressure in the system is lower than the set value, nitrogen flows from the nitrogen cylinder into the nitrogen balance cylinder, increasing the pressure in the system by compressing nitrogen. When the pressure in the system is higher than the set value, nitrogen flows out of the nitrogen balance cylinder, reducing the pressure in the system by expanding nitrogen. Through this dynamic compression and expansion process, the system can maintain a relatively stable pressure environment.

However, the practicality of this technical solution is low. When a single device is damaged, the device needs to be shut down for maintenance, which affects the use performance of the technical solution. UTILITY MODEL CONTENTS

[0014] 1. The design of two groups of nitrogen cylinders can provide more stable and uniform gas pressure output. When the pressure of one group of nitrogen cylinders decreases, the other group of nitrogen cylinders can quickly supplement the pressure, thereby ensuring the stability of the overall system pressure.
