The hood-type ventilation tube to the drainage system within the air flow, pressure stability, waterproof seal break provided with the atmosphere communicating pipe. Second, cover outtake performance can be divided into four points: 1, the emissions of toxic or harmful gases inside the drainage channels out to meet hygiene requirements; 2, outtake to complement fresh air to the reservoirs, water tanks and drainage channels to reduce the corrosion of the metal tube and prolong life;, tanks, tank vent pipe in order to improve the capacity of the drainage system should be set up more than two (cite a roton an intravenous drip when the bottle down the liquid will flow must interpolating an outtake, through the atmosphere at one end, and the gap between the one end surface and the bottom of the bottle, preventing formation of negative pressure in the pipe, to ensure smooth drainage) prevent stagnant water forming, odor, to reduce the amplitude of the pressure fluctuations, the protection of the water seal, preventing water seal damage. 4, can quickly reservoir and water vapor in the tank and harmful gases discharged built-the gauze gauze effectively prevent prevent vector, insects and dust to enter in order to destroy the water quality. Third, the hood-type outtake Model: Z-200, Z-300, Z-400, Z-600. Cover outtake description: 1, snorkel design gas flow rate of 5ms, filtered (mesh, cloth) layer gas average velocity of 075ms, filter cloth should be installed using the same material for suture, the inner cover available non-toxic and non- metal materials; 2, outtake the casing layer thickness (H3) 00m, 05m, 10m three designs suitable for the southern region, 00m, 05m apply to the central region, 10 suitable for cold regions. 3 after welding rust, anti-corrosion requirements based on customer design requirements. Conditionally regional ventilation cap FRP or stainless steel material produced according to the design requirements, in order to achieve a better anti-corrosion and extend the service life. The above is the cover type ventilation tube, the introduction of the elbow outtake If you have any questions, please contact us for the latest information cover-type the outtake or bends outtake price, manufacturer, material, structure and use of .
