1. The installation position of the exhaust valve should meet the standards and design requirements, and should be fixed firmly, the surface should be flat and not deformed, and the adjustment should be very flexible and reliable.
2. The manual drive device of the smoke exhaust valve or the exhaust port should be fixed and installed in a position that is clearly visible and easy to operate between 1.3m and 1.5m from the floor of the building. The operation of the manual drive device should be flexible.
3. The debug of the exhaust valve should be done: carry out manual opening and reset tests, the valve action should be sensitive and reliable, and the tripping wire connection of the remote control mechanism should not be loose or fall off; when a fire is simulated, after the corresponding area fire alarm, the same The normally closed air supply outlet of the fire compartment and the smoke exhaust valve or exhaust outlet in the same smoke prevention compartment should be opened in linkage; the status signal after the valve is opened should be fed back to the fire control room, and the corresponding fan should be able to start in linkage after the valve is opened.
4. The exhaust volume of each exhaust valve should not be greater than the allowable exhaust volume.
Adopt high-sensitivity actuator structure, precise chain signal, five gear adjustment
Switch angle, manual electric configuration is complete.
Strong airtight performance
Hot-dip galvanizing process, reasonable and scientific structure
Smooth seams and good sealing performance
seamless welding
The welding wire is fully welded, and the air leakage is large
reduced, overall performance improved.
Strong pressure resistance.Thickened material, can withstand larger,pressure, long service life.
