      鋼制拍門是各種材質拍門中的一種,是安裝在排水管的末端,有止回閥,防止外部水回灌的作用。閘門主要由閥座、閥板、密土密封環和鉸鏈四部分組成。形狀分為圓形和方形。拍門材制傳統上由各種金屬制品制成,現已發展成為多種復合材料。

      鋼拍門主要安裝在排水管的末端,以防止外部水倒出。該系列產品可分為不銹鋼、鑄鐵、型材、復合材料(FRP)等多種材料。

      ??球拍門有多種類型,如浮箱門、平翻門、套筒式翻板門等。

      ??它是一個安裝在排水管出口附近的單向閥。當河道潮位高于水管出口且壓力大于管內壓力時,擋門板自動關閉,防止潮水涌入排水管。目前,該門分為懸掛式、單門/雙門、節能等多種材質。

      Steel flap door is one of various materials, is installed at the end of the drain pipe, with a check valve to prevent external water recharge. The gate is mainly composed of four parts: valve seat, valve plate, dense soil sealing ring and hinge. The shapes are divided into circles and squares. Racket door material is traditionally made of various metal products, and has now developed into a variety of composite materials. The steel flap gate is mainly installed at the end of the drain pipe to prevent the external water from pouring out. This series of products can be divided into stainless steel, cast iron, profile, composite material (FRP) and many other materials. There are many types of racket doors, such as floating box doors, flat flip doors, sleeve type flip doors, etc. It is a one-way valve installed near the outlet of the drain pipe. When the tidal level is higher than the outlet of the water pipe and the pressure is greater than the pressure in the pipe, the baffle plate closes automatically to prevent the tide from flowing into the drainage pipe. At present, the door is divided into suspension, single door / double door, energy saving and other materials.
