无锡弧形钢制闸门的特点 重量轻：约为铸铁闸门的1/3重量； 耐腐蚀：耐酸碱及大部分腐蚀性化学品及污水、海水； 密封性好：采用橡胶对金属密封，止水胶圈为空心结构，密封性能好； 力矩小：由于门板重量轻，门板与导轨之间的摩擦阻力小，故使得手轮操作力矩不大于100N； 独特结构：采用可靠的温度和刚度的焊接结构，高性能的密封件保证闸门的有效启闭，独特的密封和楔块设计使得闸门启闭更加苛刻，并能受较大反向水位。 寿命长：由于门板与导轨之间只有到后一小段密封时接触，密封面磨损非常小，不锈钢闸门寿命长达15年以上，碳钢闸门使用寿命10年以上； 维修方便：楔形块可做调整，经多年使用后，如出现局面渗漏现象，只需调整楔形块增加止水胶圈压缩量即可，省时省力，维修成本低。弧形钢制闸门优点和缺点: 一、优点: 1)依据工程需要，可封闭相当大的孔口尺寸； 2)闸墩的厚度较小； 3)没有影响水流流态的门槽，泥沙多时工作状态好； 4)启闭力较小； 5)埋设件数量较少等。 二、缺点 1)需要较K的闸墩； 2)闸门所占的空间位置较大； 3)工作闸门不能提出孔口以外进行检修维护，也不能在孔口间进行互换性，对土建结构要求较高。Steel gate features light weight: about 1/3 of the weight of cast iron gate; corrosion resistance: acid and alkali resistance and most of the corrosive chemicals and sewage, seawater; good sealing: the use of rubber sealing metal, water sealing rubber ring for the hollow structure, sealing performance is good; torque is small: due to the light weight of the door plate, the friction between the door plate and the guide rail Small friction resistance makes the handwheel operating torque less than 100N; Unique structure: reliable temperature and stiffness of the welding structure, high-performance seals to ensure the effective opening and closing of the gate, unique sealing and wedge design makes the gate opening and closing more rigorous, and can withstand a larger reverse water level. Long service life: because the door plate and the guide rail only contact to a small section of sealing, sealing surface wear is very small, stainless steel gate life up to 15 years, carbon steel gate life over 10 years; easy maintenance: wedge block can be adjusted, after many years of use, if there is a situation of leakage, just adjust the wedge block increase The compression capacity of the watertight apron can save time and labor and maintain low cost. The advantages and disadvantages of curved steel gate are as follows: 1) According to the engineering requirements, it can be closed considerably large orifice size; 2) the thickness of pier is small; 3) the gate groove has no effect on the flow pattern, and the working condition is good when sediment is abundant; 4) the opening and closing force is small; 5) the number of embedded parts is small. 2. Disadvantage 1) The pier needs to be larger than K; 2) The gate occupies a larger space; 3) The working gate can not be put forward outside the orifice for maintenance, nor can it be interchangeable between orifices, higher requirements for civil structures.
