衡水水利机械厂-铸铁拍门价格,钢制拍门价格,玻璃钢拍门价格

The door is installed at the tail end of the drainage pipe, and has a check valve to prevent the function of external water backfilling. The flap gate is mainly composed of four parts: the valve seat, the valve plate, the dense soil sealing ring and the hinge. The shape is divided into round and square. The material of patting door is traditionally made of various metal products, and now it has developed into many kinds of composite materials.

拍门——主要安装在排水管道的尾端，用于防止外水倒灌。材质分为不锈钢、铸铁、型钢、复合材料(玻璃钢)等多种材料。

The flap door is mainly installed at the tail end of the drainage pipe, which is used to prevent the external water from flowing backward. The material is divided into stainless steel, cast iron, section steel, composite material (FRP) and many other materials.

而拍门又分为很多种，比如，浮箱式拍门，平板式拍门，套筒式拍门等等。

And there are many kinds of racket doors, such as floating box door, flat flap door, sleeve type door and so on.

是安装在江河边排水管出口的一种单向阀，当江河潮位高于出水管口，且压力大于管内压力时，拍门面板自动关闭，以防江河潮水倒灌进排水管道内。目前拍门分为悬挂式，单开门/双开门,节能型等型号。

It is a one-way valve installed at the outlet of the river and river. When the river tide is higher than the outlet pipe, and www.linyibanjia.net.cnwww.dianlancaoo.cn www.diandongmeni.cn www.jiningbanjia.com.cnwww.shensuomenx.cnwww.uxingcao.com.cn the pressure is greater than the pressure inside the pipe, the panel is automatically closed in order to prevent the river water from pouring into the drainage pipe. At present, the door is divided into suspension type, single door / double door, energy saving and so on.
