Concentrated gas supply of ternary mixed gases is a new technology of protective gas supply in factories in recent years. Concentrated gas supply of ternary mixed gases is an upgrade based on the original centralized gas supply system. By adding ternary mixed gases proportioning cabinet, it has been used for welding and cutting.

The key to the construction of three-component mixed gas centralized gas supply system lies in the sealing of the whole system and the production performance of mixed gas. Maintaining good sealing of ternary mixed gas centralized gas supply system can reduce the risk of gas leakage and maintain the purity of gas supply, which plays an extremely important role in operation and use safety. Previously, the explosion tragedy of Zhangjiakou Chemical Plant in Hebei Province was caused by the leakage of pre-ignited fire of vinyl chloride gas holder, so the sealing performance of gas supply system must be confirmed again and again.

In order to produce ternary mixture gas, it is necessary to add a ternary mixture gas proportioning cabinet in the gas supply equipment. Because of the need to control the pressure and proportioning accuracy of the three-way gas at the same time, the technical requirements of the ternary mixture gas proportioning cabinet for manufacturers are very high. Excellent performance of ternary gas mixing cabinet must achieve consistency of mixing accuracy, and uniform mixing output pressure stability. If this requirement is not met, gas supply terminal will not play its due protective effect.

Due to the use of self-patented integrated precision mixing and mixing device, the three-component mixing cabinet can meet the above requirements easily. The mixing process is not affected by the air pressure fluctuation. The accuracy error of the three-component mixing gas is not more than 1%. This very high mixing accuracy is very helpful for welding work.

At the same time, in order to facilitate the use of work, the infrared online analyzer controls the mixing device. Workers only need to set three kinds of gas mixing values. The operation is simple and the display is intuitive.

In order to meet the needs of large-scale enterprises, it also has a large flow of ternary gas mixing cabinet to meet the needs of large flow of gas, which can realize uninterrupted workshop gas supply, ranking first in the domestic industry.

At present, the three-component mixed gas centralized gas supply system has been installed and put into operation in many factories. It runs normally and has good performance.
