Factory Direct 1.5 m * 1.5 m flat arched iron gate, various types of hoist gate. New River County Water Machinery Plant Wanyuan a cast iron gate main purposes: iron gate is mainly used for water supply and drainage, flood control, irrigation, water conservancy, hydropower projects, for the cut-off, clear water or regulate the water level of the effect, according to the Ministry of Construction General AWWA standards and American standards of 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. Second, the iron gate structural features: 1. iron gate by the door, gate, rail, seal, drive screw, lifting block nut / lug and adjustable sealing mechanism and other components, including door frames and shutters are made of quality gray cast iron or ductile iron, rails symmetrically arranged with stainless steel bolts and pins connected by two side ends of the door frame (for small and medium caliber of the gate, which can be used with the door frame rail pouring into one), rail length is generally open to all high gates 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, and precision machining with research, so 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 turn on the water, off the water or the purpose of adjusting the water level. Third, the iron gate main technical performance parameters: 1. Model Specifications: Gate: Ming rod PGZ \ PZ DN200 ~ DN2500mm 2. iron gate key performance indicators: a) with the gap ≤0.1㎜ gate sealing surface, sealing seat thickness is 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.
