按制造門葉的材料分為鋼閘門、鑄鐵閘門、不銹鋼閘門、鑄鐵鑲銅閘門、木閘門、鋼筋混凝土閘門和組合材料閘門。另外,有些閘門
According to the materials used to manufacture gate leaves, gates are divided into steel gates, cast iron gates, stainless steel gates, cast iron copper inlaid gates, wooden gates, reinforced concrete gates, and composite material gates. Additionally, some gates
如翻板閘門可借助水力自動啟閉,稱為水力自動閘門。選擇閘門形式需要考慮其在水工建筑物中的位置、尺寸、設計水頭、運用條件、制造能力和安裝技術水平等因素,要求做到泄流時水流條件好、止水嚴密、啟閉力小、操作簡便靈活、檢修維護方便等。平面閘門和弧形閘門是_常用的門型。在工作閘門中,大型露頂式閘門和高水頭潛孔式閘門多用弧形閘門,船閘上多用人字閘門和橫拉閘門,檢修閘門和事故閘門一般都用平面閘門。制造門葉的材料近代多用鋼材,而鋼筋混凝土多用做需要借自重關閉施工導流底孔的封堵閘門。此外,在壓力管道中使用的將門葉、外殼和啟閉機械組成一體的控制設施,通稱閥門。
A flap gate that can be automatically opened and closed by hydraulic means is called a hydraulic automatic gate. The selection of gate form needs to consider factors such as its position, size, design head, operating conditions, manufacturing capacity, and installation technology level in hydraulic structures. It is required to achieve good water flow conditions, tight water stop, low opening and closing force, easy and flexible operation, and convenient maintenance during discharge. Flat gates and radial gates are commonly used types of gates. In working gates, large exposed top gates and high head down the hole gates often use radial gates, while in ship locks, herringbone gates and transverse pull gates are commonly used. Maintenance gates and emergency gates generally use flat gates. The material used to manufacture gate leaves in modern times is mostly steel, while reinforced concrete is often used as a sealing gate that needs to close the construction diversion bottom hole by its own weight. In addition, the control facilities used in pressure pipelines, which are composed of door leaves, shells, and opening and closing machinery, are commonly known as valves.
