闸门依据使用场合可区分为： Gate on the basis of using occasions can be divided into: ○1(渠道闸门)用于渠道中间，作截流用，一般用于三向密封； Among channels (gate) is used to channel 1, for intercepting, commonly used in three to seal; ○2（制水闸门）用于水道进出口则做为开启或关闭，一般用于四周密封； A. 2 water gate (system) used in waterway import and export is as open or closed, commonly used in sealing around; ○3（调节闸门）用于调节水流大小； A. 3 (adjusting gate) used to adjust the flow; ○4（堰门）用于调节水位。 4 (weir door) used to adjust water level. 特点 The characteristics of 重量轻：约为铸铁闸门的1/3重量； Light weight: the weight is about 1/3 of the cast iron gate; 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； Corrosion resistance: resistance to acid and alkali, and majority of corrosive chemical and sewage, sea water; Good sealing: use rubber to metal seal, water stop aprons for hollow structure, sealed performance is good; 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； Moment: due to the light weight of door plank, door plank and guide the frictional resistance between small, so the hand wheel makes the operating torque is not more than 100 n. 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。 Unique structure: the reliable temperature and stiffness of the welding structure, high performance sealing parts to ensure the effect of the gate opening and closing, unique sealing and wedge design makes the valve opening and closing more demanding, and can be affected by large reverse water level. 寿命长：由于门板与导轨之间只有到最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； Long life: as the door plank with only a small segment of seal at the end of the contact between guideway, sealing surface wear is very small, stainless steel gate is over 15 years of life, the service life of the carbon steel gate more than 10 years; 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； Easy maintenance: wedge block to do adjustment, after years of using, such as a leakage phenomenon, just adjust the wedge block displacement can increase the water stop aprons,
