Explain leafy exhaust port functions and technical parameters leafy air vents often installed in the front room stairs, vertical wall, I produced a variety of types of multi-leaf smoke outlet pressure delivery outlet acceptance, explain below electric multi-leaf smoke vents about relative performance and features: its main technical parameters: runtime operating voltage / current: DC24V / 0.5A. Amount of air leakage is 290m3 / m2 · h≤700 (pressure 1000Pa time). Temperature sensor operating temperature of 280 ℃. It is composed of body, valves, bushings, thin actuators, grille panel components. Usually do not use normally closed, manual open, manual reset closed. Usually also should pay attention to maintenance to increase service life. Functional and technical specifications leafy exhaust port is mainly these, I believe we already know, and we must be based on the above instructions to select the right product, so its performance is fully displayed, is to continuously improve our work efficiency. How will the pressure outlet properly installed in the building? Current Position: Home> NEWS pressurized outlet in the building has a very good use of effects pressure delivery outlet, the construction of essential goods. During the installation of building positive outlet picture outlet pressure is relatively simple to install, however, is simple, but can not be ignored, the following, to learn together under pressure outlet of the correct installation of it. Method One, pressurized stairwell of outlet should be self-hanging type Grille or positive outlet / multi-leaf smoke vents (body + panel form) positive outlet setting, when the use of positive pressure outlet ( When the multi-leaf exhaust port), should be provided with open fan chain electric valve on its pressure fan of the suction pipe. Method two, ventricular pressure outlet should be opened or automatic fire alarm linkage NC Grille open for on-site manual. Method three, mechanical pressure outlet of the wind speed of not more than 7m / s. Outlet section stairwell stairwell by the average of the total air volume calculation, 50% of the outlet section of the front room by the front room of the total air volume. Method IV, ventricular mechanical pressure outlet should be set in the wall near the ground. Five methods, mechanical pressure blower can set one or more. Pressurized air supply room should adopt the fire resistance of not less than 2.5 hours and 1.5 hours of wall separated from the other parts of the floor, the door on the wall should be Class A fire doors. Outlet pressure air supply equipment has now become an essential major buildings, the outlet of the application brought us a more comfortable environment. Effective pressurized air outlet is set in a building, it can really be safe. Pressure delivery outlet height, pressure delivery outlet, Sheng clean air conditioning provided by the Texas Air Conditioning Equipment Co., Ltd. Sheng purification. Texas Air Conditioning Equipment Co., Ltd. Sheng-purification (www.dzhffj.com) strong, credible, in Dezhou fan, ventilation equipment industry has accumulated a large number of loyal customers.
