Automatic interlock system of reverberatory Oxy-Acetylene gun
Automatic interlock system is an important part of the reverberatory oxy-acetylene gun system. As a machine driven by high-pressure oxygen and high-pressure acetylene and relying on the burning and melting of their mixtures to work, this system must have a reliable and safe interlock system to avoid any accidents, such as the machine bursting.
The automatic interlock system includes multiple parts, such as the gas-stop control device, the flame sensor, the gas control system and the safety protection device. All of these parts take an important role in ensuring the safety of the machine.
The gas-stop control device should be equipped with stop off and limit function, which means that when the oxygen and acetylene pressure is higher than the corresponding setting values, the system will be force-shut, and the oxygen and acetylene will not be supplied to the oxy-acetylene gun.
The flame sensor mainly detects the oxygen and acetylene ignition state, which is one of the most essential functions of the entire interlock system: the oxygen acetylene flame that is not extinguished in time will cause machine overload, resulting in the bursting of the oxygen-acetylene gun. Therefore, the flame sensor is responsible for detecting the flame of the oxygen-acetylene gun, and through the contactor pressure of the flame, it can accurately control the flame switch and the flame state, thus ensuring the normal operation of the reverberatory oxygen-acetylene gun.
The gas control system is composed of the primary, secondary regulators, and rotameter, which are responsible for controlling the gas supply pressure and quantity. In case of any loose, leakage and other abnormal phenomena, the gas control device should take effective measures to protect the safety of the system.
The safety protection device is a switch in the interlock system, which is used to monitor the normal and abnormal state of the system, especially in the case of fire, electric shock, and other accidents, the interlock system should respond immediately to shut the system down.
In a word, the automatic interlock system of the reverberatory oxygen-acetylene gun should have reliable and safe functions to ensure the smooth operation of the oxy-acetylene gun system, and prevent accidents from happening. Through the combination of these safety interlock system parts and components, the operator can be ensured of a safe working environment.
