Factory direct arc 0.20.2m hoist iron gate gate steel gate

Factory direct arc iron gate 0.2 * 0.2m gate hoist steel gate New River County Water Machinery Plant Wanyuan First, the use of cast iron gate, is used to close and open water conservancy construction activity over the water orifice. The role of the gate is needed all or part of the closing and opening over the water openings to the regulator, downstream water level, discharge flow. Widely used in agricultural irrigation, aquaculture, agriculture economic development zone, sewage treatment, water conservancy and power stations, reservoirs, rivers (locks, dams, culverts, pipes), flood control, drought, water storage, power generation, navigation, over wood and exclusion silt and other floating debris and other water, return water engineering equipment, mountains, plains, can be used without electricity. Second, the structure of cast iron gate, the gate, the gate frame, hanging seat, plate, closed plate, anchor bolts, standard parts and other components. Third, the principle iron gate at the opening and closing movements of the role of the gate in the gate frame on the slide, the next slide, to some or all of the opening and closing over the water orifice. Under the pressure of the water column, forced displacement of the downstream gate, close the gate frame sealing surface to ensure good sealing effect, to regulate water flow and control purposes. Fourth, the technical characteristics of the iron gate, from the design, manufacture, installation and acceptance, corrosion, raw materials into the plant, parts processing, process, quality inspection, product sales and after-sales service all of the implementation ministerial standards. Ministry of Water Resources hydraulic metal structure was identified Quality Inspection Center, reach hydraulic engineering technical requirements, product performance and manufacturing precision to the domestic industry with the advanced level. Iron gate with good looks, simple structure, safe operation, hoist flexible and reliable operation, easy installation, water tight seal, good sealing performance, good water impermeability, corrosion resistance strong, able to withstand greater water pressure small friction, good water control, rational allocation of water to ensure the safe operation of the river, long life, and low maintenance cost five, installation and adjustment iron gate, be sure to check before installing gates and set aside two largest dimensions pouring cement foundation arranged orifice structure, are consistent with the basic arrangement of four weeks orifice size must be greater than the maximum gate size of 20 cm is appropriate appearance four weeks. 1, the front gate installation, first determine the direction of flow, and must be corrected gate on the right bottom horizontal frame height positions of the plane, the plane gate bottom horizontal frame must be higher than the river (or channel bottom) plane of 0.5 m is appropriate, to prevent water impulse, stone, sand, hardwood and other floating debris rushed into the gate groove bottom horizontal frame, causing the gate can not fall into place, affecting the sealing effect. 2, the front gate installation, first check all parts of the connecting bolts are caused by loose during shipping and handling, if there is loose, use a wrench to tighten. 3, and then check the box and on the two sides and the gate, the gate frame around the lower transverse seal the junction plane is misplaced, if misplaced, apply wrench to loosen the bolt connections, will only be adjusted within the water around the same level, then tighten. 4, when the shutter assembly, in order to make the gate and the gate frame sealing surface friction fit tighter, reducing the gap after installation, the gate on the upper and lower horizontal frame compression card installed iron gate established on both sides of the frame wedges on the increase in the top wire, pay attention to the gap adjusted after the rear latch and the top wire removed, it will not affect the gate opening and closing. 5, when the gate installation, you should install the whole place is prohibited gate, gate frame installed separately, to prevent the gate frame bending deformation, affect the sealing effect, and headstock. 6, gate lifting into the post cast concrete structure set aside two basic arrangement of apertures, we must ensure that both sides of the vertical gate frame with a long spirit level close to the vertical line, the upper and lower horizontal frame with a long spirit level brake abut on the horizon After hoisting the whole gate, adjust the front and rear, left and right, up and down in the correct position, and then adjust the anchor bolts and pre-engineered steel welding firm. And then detect a gap feeler water at each stop, while the gap is greater than 0.2mm at adjusted with high strength bolts, the maximum gap between each stop to make sure the water is 0.2mm or less. Then the two sides and the dorsal surface of the shutter gate with a steel or wooden support frame tight to prevent pouring cement squeeze, causing the two sides and the gate frame bending, impact on the gate in the chute gate box, sliding. After confirmation the last two can be pouring cement. 7, gate two after pouring cement in a timely manner to flow into the gate, the gate frame, closed the platen gap grout clearance is completed, prevent the slurry solidification, influence gate opening and closing. Wanyuan water conservancy hoist gate Scope For water systems, municipal sewage, urban flood control and drainage, sewage treatment plants, water plants and so on. Product specifications and categories shoot the door specifications of round knock on the door and knock on the door square two, according to the size and shape of the outlet design and production; it has an automatic opening and closing function; sealing, good anti-reflux properties.
