many factories will be applied to the automatic exhaust valve, mainly in the steam this piece, automatic exhaust valve of help is very big.

according to the load change in the process of using steam, using two ways to stress. Automatic exhaust valve station by the main pressure reducing valve, safety valve, steam trap, filters, cut-off valve, pressure gauge and the pipeline.

when the automatic exhaust valve back down from the main relief valve setting value, the main and deputy relief work at the same time; When steam safety valve back down in the auxiliary of the relief Industrial Valves setting value of 0. 45 mpa, higher than that of the main relief Industrial Valves setting value of 0. At 3. 7 mpa, only assisted relief work; When the automatic exhaust valve back pressure is higher than secondary relief Industrial Valves set value 0. 45 mpa, the main and auxiliary safety valve does not work, at the same time keep the back pressure valve. Auxiliary pressure relief valve set point.

in the actual production, when no bath cycle, steam is lesser, automatically by the auxiliary exhaust valve to reduce steam supply. When steam content increases, the steam supply is insufficient, just below the main relief valve setting pressure, the pressure reducing valve and auxiliary valve work at the same time.

due to the high precision automatic exhaust valve adjustment, can reach 0. 01 mpa, make the main and auxiliary pressure reducing valve can work in parallel. At the same time, under the different steam, adopt different under pressure reducing valve, stable flow and pressure of steam after decompression, avoid the piston pressure reducing valve in original state caused by cavitation and damage.

that is automatic exhaust valve in the application of the steam.
