Gas-liquid distributor capable of avoiding liquid countercurrent

The utility model provides a gas-liquid distributor capable of avoiding liquid backflow, which relates to the technical field of internal components of reactors and comprises a mounting top tray, a connecting movable seat is connected to the center of the surface of the mounting top tray, a connecting spring is connected to the bottom surface of the connecting movable seat, and check balls are connected through the connecting spring. When the flow of liquid feeding is small, the pressure of the non-return ball on the ball seat can be effectively reduced through the arrangement of the connecting spring, the resistance borne by the liquid feeding when the liquid feeding passes through the bottom of the non-return ball can be reduced, and the using effect of the gas-liquid distributor is enhanced when the flow of the liquid feeding is small; when the flow of fed liquid is large, the impact of the fed liquid can be relieved, when the fed liquid impacts the connecting spring, the spring is compressed, the non-retu
