Problems solved by technology

The existing problem is: if the hydrogen gas produced in the electrolysis process is not discharged in time and effectively, the hydrogen gas will flow with the electrolyte in the electrolytic cell, increasing the impedance of the electrolyte and reducing the current efficiency; at the same time, too much hydrogen accumulation will also cause It affects the stable operation of the generator, so it is necessary to use a gas-liquid separation device to discharge hydrogen
This kind of exhaust valve is greatly affected by the pressure in the gas-liquid separation tank. When the pressure in the separation tank is high, the corresponding counterweight will increase, and when the pressure in the separation tank is low, the counterweight will decrease. Therefore, only Can correspond to a stable working condition
Moreover, the valve ball of the exhaust valve moves up and down very frequently and fluctuates greatly, causing the liquid level in the gas-liquid separation tank to fluctuate frequently.
