Abstract
The utility model provides an air port rain-proof louver. The louvers of the air port rain-proof louver are divided into a rain partition area, a guide area and a rain-proof area, and three reinforcing installation ribs are arranged. The air port rain-proof louver can not only meet the ventilation requirement, but also avoid the rain water from entering, has high available ventilation rate and low wind pressure loss, and the outlet air direction is the same as the airflow direction of an air outlet of a silencer.
Description
Technical field
The utility model relates to the rainproof louver in a kind of air port, especially can prevent the rainwater invasion and attack, and effectively air-out area is big, does not change the rainproof louver in air port of air-out direction.
Background technology
Equipment sound insulation room produces heat and waste gas for preventing in the equipment running process; Should in airtight equipment sound insulation room, ventilation system be set; For preventing that noise of equipment from passing through ventilation system and outwards propagating, at inlet and outlet the outlet and inlet silencer is set, according to the hot gas rising principle; The air intake silencer is arranged on equipment sound insulation top, room, and the air-out silencer is arranged on equipment sound insulation bottom, room.Simultaneously, answer strictness to prevent that the air-out air-flow from getting into air inlet, guarantees the ventilation system operate as normal.Should install at the outer air-out silencer air outlet of equipment sound insulation chamber and can satisfy the rainproof louver in air port that device that air-conditioning requirement can prevent that again rainwater from attacking promptly is generally called.But at present general air port rainproof louver available ventilation area is little, and ventilation rate is low, causes the high air loss of wind speed big.Air-out direction has down changed the airflow direction of silencer air outlet, causes the air-out air-flow to get into the air inlet of air intake silencer easily, is unfavorable for the normal circulation of air-flow.
Summary of the invention
Little in order to overcome existing air port rainproof louver available ventilation area, ventilation rate is low, causes the high air loss of wind speed big; Air-out direction has down changed the deficiency of the airflow direction of silencer air outlet, and the utility model provides a kind of air port rainproof louver; The rainproof louver in this air port can not only satisfy air-conditioning requirement can prevent the rainwater invasion and attack again; And the available ventilation rate is high, and air loss is little, and air-out direction is consistent with the airflow direction of silencer air outlet.
The utility model solves the technical scheme that its technical problem adopted:
The page or leaf sheet of the rainproof louver in air port is divided at a distance from rain belt, anti-rain belt, water conservancy diversion district, be provided with three and strengthen installing rib.Air-out direction is consistent with the airflow direction of silencer air outlet, prevents silencer air outlet air-flow down, stops the air inlet that the air-out air-flow gets into the air intake silencer, helps the recycling replacing of equipment sound insulation chamber gas.Separated rain belt is perpendicular to plane, water conservancy diversion district; Anti-rain belt makes progress 45 ° of angles in the water conservancy diversion district; Anti-rain belt upper flat at a distance from top, rain belt and next louver page or leaf sheet is neat; Spacing between the anti-rain belt of the water conservancy diversion interval distance of bottom, rain belt and next louver page or leaf sheet and upper and lower two louver page or leaf sheets is consistent, can effectively intercept the invasion and attack of outside rainwater.Because rainproof fauna makes progress into 45 ° of angles in the water conservancy diversion district; Spacing between the anti-rain belt of upper and lower two louver page or leaf sheets is the smallest effective passage of the rainproof louver in air port; Strengthening installing rib is arranged at a distance from the bottom in top, rain belt, water conservancy diversion district and the top of anti-rain belt; Do not take the space between the anti-rain belt of upper and lower two louver page or leaf sheets, do not influence air port rainproof louver available ventilation rate.It is inboard to use Closed End Blind Rivet that louver page or leaf sheet is installed in the load-bearing frame structure.
The beneficial effect of the utility model is to prevent under the prerequisite that rainwater is attacked that satisfy the requirement that improves ventilation rate and can reduce air loss again, air-out direction is consistent with the airflow direction of silencer air outlet.
