(ZH) 通风阀
Abstract: front page image
(EN) A ventilation valve, comprising a cylindrical valve body (1), a gearbox (2), a plurality of fan-shaped vanes (3) and a drive device (4), the gearbox (2) being arranged in the center of the valve body (1), and a geared mechanism being provided inside the gearbox (2). The drive device (4), by means of a geared drive mechanism, causes the vanes (3) to rotate in a same direction, each around its own central shaft; the vanes (3) are arranged within the valve body (1) in a uniform distribution; the geared mechanism comprises a first central gear (23) and a second central gear (24) sleeved upon a same supporting shaft (25); between the first central gear (23) and the second central gear (24) are provided a plurality of gears, one each of which is arranged at that end of one of said central shafts which extends to within the gearbox (2), each of said gears engaging with both said first central gear (23) and said second central gear (24). Also arranged within the valve body (1) is one or a plurality of air flow meters (6), the distance between the central axis of each of said one or plurality of air flow meters and the central axis of the valve body being not equal. The present ventilation valve precisely controls air flow and is safe and reliable, while featuring improved geared mechanism security and reduced wear and tear, thus prolonging service life.
(ZH) 一种通风阀,包括圆筒状的阀体(1)、齿轮盒(2)、多块扇面状的叶片(3)以及驱动装置(4),阀体(1)的中心设置有齿轮盒(2),齿轮盒(2)内设置有齿轮机构;驱动装置(4)通过驱动齿轮机构从而驱动叶片(3)绕各自的中心轴进行同向转动;叶片(3)均布设置于阀体(1)内,齿轮机构包括套设于同一支撑轴(25)上的第一中心齿轮(23)和第二中心齿轮(24),第一中心齿轮(23)和第二中心齿轮(24)之间设置有多个设置于各中心轴伸入齿轮盒(2)内的一端的齿轮,各齿轮均同时与第一中心齿轮(23)和第二中心齿轮(24)相啮合;阀体(1)内还设有一个或多个风量仪(6),一个或多个风量仪的轴线到阀体的轴线的距离不相等。该通风阀可精确控制通风量,安全可靠,提高了齿轮机构的安全性,有效减小了使用损耗,延长了使用寿命。
