Description

Technical Field

[0001] The utility model relates to the technical field of gate valve forging processing, in particular to a heat treatment device for high-temperature and high-pressure gate valve forgings. Background Technique

[0002] A gate valve is a kind of valve, which has the characteristics of small flow resistance, large height, long opening and closing time, and high temperature and high pressure resistance. The opening and closing part of the gate valve is the gate plate, and the moving direction of the gate plate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted. In order to ensure the quality of the gate valve, it is necessary to heat-treat the gate valve forging. Heat-treating the forging is an important link in forging processing, and it is of great significance for improving the strength, hardness, wear resistance and corrosion resistance of the forging.

[0003] After retrieval, in the application with the patent application number 202121844280.6, a heat treatment device for forgings is disclosed, including a base. Four corners at the bottom end of the base are respectively welded with support legs. A heating furnace is fixed on the top end of the base. A top seat with a hollow interior is fixed on the top end inside the heating furnace. An activity seat is arranged at the bottom end inside the top seat. An installation table is arranged inside the heating furnace. A plurality of groups of hooks are vertically arranged on both sides and at both ends of the bottom end of the installation table. Installation grooves are respectively arranged inside both sides and at both ends of the installation table. An inner cavity is arranged inside the bottom end of the hook.

[0004] Although the heat treatment device for forgings can drive the installation table to rotate and the multiple groups of hooks at its bottom and the forgings to rotate inside the heating furnace through the setting driven by the servo motor, and then heat the forgings evenly, the heat treatment device for forgings can only drive the forgings to revolve inside the heating furnace, while the forgings themselves cannot rotate, and it is not convenient to adjust the height of the forgings, resulting in insufficient heating of the forgings.

[0005] Therefore, we have proposed a heat treatment device for high-temperature and high-pressure gate valve forgings. Content of the Utility Model

A gear disc is fixedly installed on the top surface of the rotating rod. A gear ring meshing with the gear disc is fixedly sleeved on the inner wall of the heating furnace.

[0010] Preferably, the turntable is rotatably sleeved on the inner wall of the heating furnace through a bearing ring, so as to facilitate the reinforcement of the turntable and enable the turntable to rotate stably inside the heating furnace.

[0011] Preferably, six circular holes and rotating rods are arranged in an annular array distribution, and adjacent gear discs do not contact each other, so that the situation that adjacent gear discs interfere with each other and then the gear discs are difficult to rotate can be avoided.

[0012] Preferably, an electric push rod is fixedly installed on the bottom surface of the rotating rod, and a U-shaped plate is fixedly installed on the bottom surface of the electric push rod. Both ends of the U-shaped plate are fixedly installed on the side wall of the placing cylinder.
