Steel gates are often used to open or close some of the water intakes in hydraulic engineering, which can play a very good role in regulating the flow and controlling the water level, and help all kinds of ships smoothly through the various gates. Because of the different topography and water-stone in each place, the types of steel gates we use will be different, but the two common gates are plane steel gates and arc steel gates, so what is the difference between them? Plane steel gates and arc steel gates are mainly based on steel gates The shape of door leaf is classified. The water-retaining panel of the plane-shaped steel gate is plane, while the water-retaining panel of the arc-shaped steel gate is made into arc in the design and manufacture. Generally, as long as you see the steel gate according to the different leaf, you can quickly know which is the plane steel gate and which is the arc steel gate. Of course, the difference between them is not only reflected in the shape, but also in the performance and use. Because of the relatively simple structure, the manufacture of plane steel gate is relatively simple, the cost is lower, the maintenance is relatively simple, and the use process is not very complicated steel circular gate. The main function of the steel circular gate is to satisfy the drainage requirement and adjust the drainage quantity. Now the steel circular gate on the market has been improved on the original basis, both in function and performance. Its interior adopts advanced manufacturing technology, under the action of strong pressure, its interior structure is strictly sealed between, and at both ends of the steel circular gate, the welding technology is used, after the completion of the production, the steel circular gate surface treatment, improve the wear resistance of the surface, as well as anti-friction ability. It will eventually improve its service life. Because of the special shape of the arc steel gate, the production process is more complicated, the price is slightly more expensive than the plane steel gate, and the installation process is more complex, but its performance is relatively high. Gate is the control equipment in various channels of water conservancy and Hydropower projects, which is widely used in small and medium-sized water conservancy and Hydropower projects, municipal water supply and drainage projects, aquaculture, farmland irrigation and other water conservancy projects. It is used to control the water level and regulate the flow. The gate consists of gate, gate frame, pressure plate, water stop pin and hanging nose. 1. Before installing the gate, check whether the bolts at the connecting parts are loosened due to transportation, loading and unloading, and tighten them if they are loosened. 2. Check whether there is any misalignment between the sealing surface of the main vertical frame and the horizontal frame. If there is any misalignment, loosen the connecting bolt to adjust the sealing surface in the same plane. 3. The whole installation should be adopted when the gate is installed, and the separate installation of the gate frame and the gate plate is forbidden to prevent the deformation of the gate frame. 4. Before the second stage of pouring, the gate is hoisted and positioned as a whole, and the correct position of the gate is found before, after that, the bolt and the reinforcement of the project are welded firmly. 5. Before the gate leaves the factory, in order to make the gate board and the gate frame close together and reduce the gap after installation, the gate above 2 meters is equipped with the pressure plate clamp iron on the upper and lower transverse frames, and the top wire is added on the inclined iron of the vertical frame. Note that after the clearance is adjusted, the top wire of the clip iron and the inclined iron will be removed to make the gate open and close.

   鋼閘門常常用來開啟或者關閉水利工程中的一些過水口，能夠起到一個很好的調節流量和控制水位的效果，幫助各種船只順利通過各個閘口。在實際的應用中由于每個地方的地形和水石有所不同，我們使用的鋼閘門的種類也會有所不同，但是比較常見的兩種閘門是平面鋼閘門和弧形鋼閘門，那么這二者之間又有何區別呢? ??平面鋼閘門和弧形鋼閘門主要是依據鋼閘門的門葉的形狀進行分類的。平面型門葉鋼閘門的擋水面板是平面的，而弧形鋼閘門的擋水面板在設計制作當中則制作成了弧形的。二者之間比較好判別，一般只要看到了鋼閘門依據門葉不同很快就可以知道哪個是平面鋼閘門，哪個是弧形鋼閘門。 ??當然，二者之間的差異不僅僅是體現在形狀上，性能用途方面也是有所差異的，平面鋼閘門的由于結構相對簡單，制造起來也比較簡單，造價也因此比較低一些，維護起來也比較簡便，使用過程也不是很繁瑣

 

鋼制圓形閘門被運用到水利工程當中，其主要的作用就是滿足排水要求，對排水量進行調節，現在市面上銷售的鋼制圓形閘門已經在原來的基礎上，無論是在功能方面，還是在性能上面，都較以前有了明顯的改善。其內部采用了先進的制作工藝，在強壓的作用下，將其內部結構之間進行了嚴格密封，而在鋼制圓形閘門兩端，則采用的是焊接技術，在制作完成之后，還要對鋼制圓形閘門表面進行處理，提高表面的耐磨性能，以及抗擦能力，終達到提高其使用壽命的作用。。而弧形鋼閘門由于在制作過程中需要對它的形狀進行特殊的打造，因此生產工藝相對復雜一些，價格也比平面鋼閘門略貴，安裝過程也比較復雜，但是它的性能是比較高的。

 

閘門是水利水電工程中各種渠道上的控制性設備，廣泛應用于中小型水利水電、市政給 排水工程、水產養殖、農田灌溉等水利工程。它是用于開啟控制水位，調節流量的作用。 閘門由閘板、閘框、壓板、止水銷、吊鼻等組成。 1、在閘門安裝前，先檢查各連接部位的螺栓是否因運輸裝卸中造成的松動，如有松動應加以緊固。 2、檢查主立框與橫框連結上的止水面是否有錯位，如有錯位則松動連接螺栓將止水面調整在同一平面內。 3、閘門安裝時應采用整體就位安裝，禁止閘框、閘板分體安裝，防止閘框變形。 4、二期澆筑前將閘門整體吊裝就位后找好前后、左右的正確位置，然后調整螺栓與工程配鋼筋焊牢固。 5、閘門出廠前，為了使閘板、閘框貼合的更緊，安裝后減少間隙，2米以上的閘門在上下橫框上安裝了壓板卡鐵，立框的斜鐵上增加了頂絲。注意在間隙調整后將卡鐵和斜鐵上的頂絲拆除，以使閘門啟閉。
