Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 4, the embodiment of the utility model provides an exhaust discharge pipe of reducible jam, including right return bend 1, left return bend 2 and straight tube 3, the upper end of right return bend 1 is the exhaust entry 11 that links to each other with the equipment blast pipe, the lower extreme of right return bend 1 is bent the back and is communicated with 3 lower parts of straight tube left, the lower extreme of left return bend 2 is for stretching into the exhaust outlet 21 in the rainwater collection cabinet, the upper end of left return bend 2 is bent the back and is communicated with 3 upper portions of straight tube right side, the lower extreme mouth of pipe department of straight tube 3 is equipped with down flange dish, down flange dish is standard flange dish, is connected with lower flange dish 31 detachable through the bolt, prevents to leak.

An upper flange plate is arranged at the upper end pipe orifice of the straight pipe 3 and is detachably connected with the upper flange seal plate 32 through two bolts. Because the lower flange plate is connected with the lower flange seal plate and the upper flange plate is connected with the upper flange seal plate through the two bolts respectively, when dust deposition is cleaned, one bolt is dismounted, so that the upper flange seal plate or the lower flange seal plate can open the upper port or the lower port of the straight pipe by rotating around the other bolt, as shown in fig. 5, wherein, fig. 5a is a front view of the flange plate connected with the flange seal plate through the two bolts; figure 5b is a top view of the flange closure plate when closed and figure 5c is a top view of the flange closure plate when open.
