为防止风门处的水沟漏风,研究了一种风门水沟密封船。密封船放在风门侧的排水沟内,能自动调节水沟断面,它既能保证水沟中的水流通,又能保证水沟处不漏风,以达到密封风流的作用。密封船结构简单,用木板或胶合板制作,外钉上旧风筒布。在船尾密封板上和水沟门框上包上40～50毫米宽的羊毛毡或胶皮,以便密封。如果沟内水流速太大或
In order to prevent air leakage at the damper of the damper, a wind gate ditch sealed vessel was studied. Sealed vessels placed on the side of the gutter drain can automatically adjust the ditch cross section, which not only ensures water flow in the ditch, but also to ensure that no leakage at the ditch, in order to seal the role of romantic. Seal ship structure is simple, with wood or plywood production, the nails on the old duct fabric. Cover the aft sealing plate and the ditch door frame with 40- to 50-mm-wide wool felt or rubber for sealing. If the ditch water flow rate is too high or
