Description

Technical Field

[0001] The utility model relates to the technical field of valve state detection, and more specifically to an RTO valve state detection device. Background Art

[0002] RTO refers to regenerative thermal oxidizer, which is a device used to treat industrial waste gas. It converts harmful gases into harmless substances through high temperature and oxidation to reduce pollution to the environment. The working principle of RTO is cyclic operation, which allows the waste gas to circulate between two combustion chambers by alternately controlling different valves and fans. This can achieve efficient heat recovery while ensuring that the waste gas is fully oxidized. When using RTO to treat waste gas, the valve needs to be opened and closed in time.

[0003] Among them, the knife-type pneumatic valve is a commonly used control valve, which is designed like a blade and can be driven by a pneumatic actuator to quickly open or close the fluid channel. However, in actual use, if the pneumatic actuator is damaged, the valve cannot be opened or closed in time. Therefore, in order to ensure the safety of the device and quickly find the fault point, it is very necessary to set up a detection device to detect the opening or closing state of the valve.
