铸铁镶铜方闸门结构特点：
The structural features of cast iron square gate with copper inlaid are as follows:
1.铸铁镶铜方闸门由门框、闸板、导轨、密封条、传动螺杆、吊块螺母/吊耳和可调整密封机构等部件组成，其中门框和闸板均由优质灰口铸铁或球墨铸铁制成，导轨左右对称布置且用不锈钢螺栓定位销与门框二侧端部连接 （对中小口径的闸门，其导轨可与门框浇注成一体），导轨长度一般为闸门全开启高度的1/2～1/3，因而整体结构强度高、刚性高、耐磨、耐腐蚀性好、承压能力大。
1. The cast iron copper inlaid square gate is composed of door frame, gate, guide rail, sealing strip, transmission screw, lifting block nut / lug and adjustable sealing mechanism. The door frame and gate are made of high-quality gray iron or ductile iron. The guide rail is symmetrically arranged on the left and right, and is connected with the two side ends of the door frame with stainless steel bolt positioning pin The length of guide rail is generally 1 / 2-1 / 3 of the full opening height of the gate. Therefore, the overall structural strength is high, the rigidity is high, the wear resistance is good, the corrosion resistance is good, and the pressure bearing capacity is large.
2.通过楔块装置的楔紧达到密封，密封材料为铜合金或橡胶，并经精密加工后配研，故密封性好。
2. The sealing material is copper alloy or rubber, and the sealing material is copper alloy or rubber. The sealing performance is good after precision machining.
3.采用预埋钢板或预埋螺栓式安装，安装、调试、使用、维护方便，使用寿命长。
3. It adopts embedded steel plate or embedded bolt installation, which is convenient for installation, debugging, use and maintenance, and has long service life.
4.品种规格齐全，适应性广。
4. Complete varieties and specifications, wide adaptability.
5.与启闭机配套使用，闸门为工作部分，启闭机为闸门开启与关闭的执行部分，启闭机由人力、电机或气动、液压机构带动传动装置的齿轮、蜗轮蜗杆等运转，驱动传动螺母或螺杆转动使闸轴作垂直升降运动，从而开启或关闭闸门，达到 水、关水或调节水位的目的。
5. It is used together with the hoist. The gate is the working part, and the hoist is the executive part of the gate opening and closing. The hoist is driven by the human, motor, pneumatic and hydraulic mechanism to drive the gear, worm wheel and worm of the transmission device to drive the transmission nut or screw to rotate to make the gate shaft move vertically, so as to open or close the gate The purpose of water, closing water or regulating water level.
