A cast iron gate copper inlay square Uses: used for drainage, flood control, water conservancy and hydropower project to closing, and clear the role of water. Especially scenic, road works, structure is not suitable for installation next set of copper rod iron gate of the occasion. Second, iron inlaid copper side gate range: cast iron inlaid copper side gate is mainly used for water supply and drainage, flood control, irrigation, water conservancy, hydropower projects, for the cut-off, dredging water or regulate the water level of the effect, according to the Ministry of Construction and the General Standard for the United States AWWA standard design and production. It uses a unique outer curved design, reasonable structure, even by force, using high-quality gray cast iron or ductile iron, stainless steel, seal and surface inlaid copper strips or rubber, and precision machining with research, to surface contact seal, sealing performance, when the seal sealing performance, can be resolved by adjusting the wedge device. Third, the cast iron inlaid copper side gate structure and working principle: 1. cast iron inlaid copper gate by the side door, gate, rail, seal, drive screw, lifting block nut / lug and adjustable sealing mechanism and other components, wherein the frame and shutter are made of quality gray cast iron or ductile iron, rails symmetrically arranged with stainless steel bolts and positioning pins and frame two side ends of the connection (for small and medium caliber of the gate, which can be used with the door frame rail pouring into one), rail the gate length is generally full opening height of 1 / 2-1 / 3, and thus the overall structure of high strength, high rigidity, wear resistance, corrosion resistance, high pressure capability. 2. wedge wedge means to seal tight, the sealing material is a copper alloy or rubber, and precision machining with research, it is a good seal. 3. Using embedded steel or embedded bolt mounting, installation, commissioning, use, easy maintenance, long service life. The full range of specifications, wide adaptability. 5. With the hoist supporting the use of the gate as the working part, hoist the gate open and closed operative hoist driven by manpower, electrical or pneumatic, hydraulic mechanism gears, worm and other gear in the operation, the drive drive nut or screw rotation axis so that the gate moves vertically, thereby opening or closing the gate, to the water, off the water or the purpose of adjusting the water level. Fourth, the iron gate copper inlay side main technical performance parameters: 1. Model Specifications: Square Gate: Ming rod ZMF DN200 ~ DN2500mm 2. Cast Iron Copper side gate key performance indicators: a) the sealing surface of the gate with the gap ≤0.1㎜, sealing seat thickness greater than 10 mm. b) the length of the sealing surface seepage per meter: Forward ≤0.7L / min m reverse ≤1.25L / min mc) Nominal ≤0.1Mpa; seal test pressure 0.1Mpa??. d) Working Environment: Temperature -20 ℃ ~ 120 ℃ Humidity: 95% Medium: water and sewage PH value: 5 ~ 10 e) Installation Position: Forward meet the water under normal conditions, in a vertical state. f) maximum working head: unidirectional compression: Forward: 10m reverse: 5m biaxial compression: both 10m g) Opening and closing speed: not less than 0.2m / min, not more than 1.5m / min. h) from the side wall of the gate frame distance ≥300㎜, ≥150㎜ ~ 250 mm distance from the bottom. V. buy items "Ocean" brand hydraulic engineering machinery should be noted: 1, ① product name and model ② side gate caliber ③ side gate material and screw length 2, have already been selected by the design unit side gate type, please Order to our sales department directly by the square gate model. 3, when the occasion is very important or the environment is more complicated, you try to provide design drawings and detailed parameters by our experts Yongjia valve Lawrence audit checks.
