Abstract

A gate valve comprises the following components: a feeding part, a gate insertion part and a material outlet part, wherein the feeding part, the gate insertion part and the material outlet part are successively connected in a horizontal direction and are internally communicated. The gate insertion part comprises a seat body and a gate plate mechanism. The seat body is connected between the feeding part and the material outlet part. The gate plate mechanism is inserted into the seat body from upper part. The inner bottom of the seat body is provided with a groove for inserting the bottom of the gate plate mechanism when the gate valve is closed. The bottom of the inner wall of the material outlet part is level with the bottom of the groove. The wall of the groove, which is connected with the material outlet part, is provided with a gap. The gap is horizontally connected with the bottom of the groove and the bottom of the inner wall of the material outlet part. When the gate valve is applied for the device for transporting high-temperature viscous medium, the high-temperature viscous medium which residues in the groove can be easily discharged from a material outlet, thus effectively preventing gate valve sealing incapability caused by cold condensation of the high-temperature viscous medium that residues in the groove, and improving reliability in use of the gate valve.
