Coke oven gas exchange cock

The coke oven gas exchange cock is a three-way cock valve with directional installation. If installed incorrectly, it can lead to gas leakage and may cause accidents. In response to the problems existing in gas exchange cocks, this article introduces a simple and effective improvement measure for gas exchange cocks, which involves drilling, tapping, and screwing in suitable short screws on one surface of the square head that matches the cock with the wrench. A portion of the screw should be several degrees higher than the plane; Mill grooves on the corresponding surface of the wrench square hole to match the short screws exposed on the square head of the plug core. This method solves the problem of misinstallation of traditional gas exchange cocks after maintenance, and improves work efficiency.

The improvement measures for preventing incorrect installation of coke oven gas exchange cocks include processing the working surface of the combination of the plug core and the square hole of the exchange wrench, installing a positioning pin on the square head of the plug core, and processing a positioning groove on the assembly surface of the square hole of the exchange wrench. Through the coordination of the positioning pin and groove, the correctness of the assembly direction of the plug core and the exchange wrench is achieved, and the installation is correct. This measure solves the problem of misinstallation that traditional gas exchange cocks are prone to during cleaning and assembly, prevents gas leakage, and improves the efficiency of cleaning and assembly.
