阀门在通风或空调系统中是一个很重要的部件。过去,一般在通风系统上常使用插板阀、蝶阀等,空调系统常用平行叶阀、对开式多叶阀等,这些阀门都程度不同的存在着一些缺点,如操作不灵活、漏风、调节范围小、气流通过阀门时不稳定等等,针对这些缺点,我们设计并试制成功了一种新型的菱形风阀(以下简称ZL S_1),现详述于下: 一、结构 ZL-S_1采用了与以前阀门完全不同的结构,它不是靠叶片转动调节风量,而是靠叶片变形来调节风量。该阀有数组菱形叶片,每组菱形叶片是由四个小叶片铰接组合而成。内设推拉机构使该菱形的形状可以变化,以此调节风量大小。推拉操纵机构的支撑、轴和套管都设在每组叶 Valves are a very important part in ventilation or air conditioning systems. In the past, plug valves, butterfly valves, etc. were commonly used in ventilation systems. Commonly used air-conditioning systems include parallel leaf valves and split-type multi-leaf valves. These valves have different degrees of weaknesses, such as inflexible operation, air leakage, and adjustment. The range is small, the air flow is not stable when passing through the valve, etc. For these disadvantages, we designed and prototyped a new type of rhombic damper (hereinafter referred to as ZL S_1), which is described in detail below: I. Structure ZL-S_1 adopted In a completely different structure from the previous valve, it does not depend on the rotation of the blade to adjust the air volume, but rather adjusts the air volume by the deformation of the blade. The valve has an array of diamond blades. Each set of diamond blades is hinged by four small blades. A push-pull mechanism is incorporated to adjust the shape of the diamond to adjust the air volume. The push-pull actuator supports, shafts and sleeves are located in each group of leaves
