What is the role of the ventilated cap in the aluminum alloy water system

Aluminum downpour system is a complex industrial industry and the requirements for chimneys are still very high. If there is no rain cap installed on the top of the existing chimney, a large amount of rain will fall into the chimney during the period when there is no smoke discharge, which will corrode the internal facilities of the chimney and shorten the use time of the chimney. Therefore, the existence of chimney covers is more necessary. Now let's introduce what the aluminum alloy breathable cap has.

　　Or the rain cap is too simple to completely block the rain, and once affected by strong winds, the top of the chimney will shake, which will not only affect the stability of the chimney, but also have some hidden dangers. The purpose of the utility model is to design a chimney rain cap, so that the top of the chimney is normal smoke and rain, so that the chimney rain prevention effect is better and the structure is more stable. In order to achieve the above purposes, the utility model provides the following technical scheme: a chimney rain cap is composed of a top cover, a plurality of exhaust chimneys, a plurality of rain cover and a connecting piece according to the diameter of the chimney. The connecting piece is fixed on the chimney, the smoke exhaust pipe is connected with the connecting piece, the wall of the smoke exhaust pipe is evenly distributed with a plurality of openings, the rain cover is installed between the two adjacent smoke exhaust pipes, and the upper part of the top smoke exhaust pipe is connected with the top cover.

　　The aluminum alloy breathable cap helps prevent rain and rainwater from flowing out of the top. The diameter of the upper exhaust pipe is smaller than the diameter of the lower exhaust pipe, forming a narrow structure at the top and wide at the bottom, making the structure of the smoke cap more stable and stable. The shape of the opening is rectangular and the two ends are semi-circular, which is conducive to the smoke exhaust and structural stability of the chimney rain cap. Too many openings will lead to the instability of the chimney rain cap structure, and too few openings will reduce the smoke exhaust effect of thchimney rain cap.

The rain cover is a trapezoidal cone. The diameter of the upper end of the trapezoidal cone is the same as the diameter of the upper exhaust cylinder. The intersection point of the vertical extension line at the bottom of the trapezoidal cone with the slope of the lower exhaust is lower than the low point of the lower exhaust opening. In strong wind conditions, it prevents rain from blowing into the opening of the exhaust cylinder. The connector is a cylindrical tube with a diameter larger than that of the chimney. The
