Nonmetal service gate

The utility model relates to the field of gates, and particularly discloses a nonmetal service gate which comprises a gate body, the gate body is installed in a gate groove matched with the gate body, and the gate body can move up and down in the gate groove. The periphery of the side, facing the downstream face of the door body, of the door groove and the periphery of the downstream face of the door body are connected with a water stop belt and a water stop strip which are used for sealing correspondingly, the water stop belt and the water stop strip abut against each other and then seal the contact face of the door body and one side of the door groove, and an auxiliary sealing assembly is installed between the upstream face of the door body and the inner side of the corresponding door groove. The space between the downstream face of the door body and the side wall of the door groove is sealed, after the door body is impacted by water, the sealing effect is better, the impact force of water flow is larger, t
