| 拍门:安装于排水管道的尾端，具有防止外水倒灌功能的逆止阀。拍门主要由阀座、阀板、水密封圈、铰链四部分构成。形状分为圆形和方形。拍门的材质传统上为各种金属制品，现在已经发展为多种复合材料。 Flap door: it is installed at the tail end of the drainage pipe and has the function of preventing backflow of external water. The flap door is mainly composed of valve seat, valve plate, water seal ring and hinge. The shape is divided into circle and square. Traditionally, the material of flap door is all kinds of metal products, and now it has developed into a variety of composite materials.框格护坡模具 箱体护坡模具 华尔街铜牛 电阻柜 接地电阻柜 电缆保护接地箱 隔离墩模具 化粪池模具 拍门相对传统的闸门有以下几点优势: The flap gate has the following advantages over the traditional gate: 1.更具节能性(如开关门无需人工施加外力) 1. It is more energy-saving (for example, opening and closing the door does not require manual application of external force) 2.使用寿命长(机械结构简单，维护方便) 2. Long service life (simple mechanical structure and convenient maintenance) 3.方便使用(开关无需人人工操作) 3. Easy to use (the switch needs no manual operation) |
