What does \"explosion-proof throat\" for fans mean? What is the principle?
An explosion-proof throat refers to the installation of a safety valve at the outlet of the fan, which prevents explosive gases from accumulating within the fan; and when such gases appear, it allows them to be quickly expelled from the fan, thereby preventing an explosion. -
How can one determine when explosive gases are present?
When pressure, flow rate, or temperature exceeds the valve’s set range, the safety valve opens quickly to discharge the explosive gases from the fan. -
