Supply of copper inlay Cast iron gate with manual hoist, good quality

Supply of copper inlay Cast iron gate with manual hoist, good quality New River County Water Machinery Plant Wanyuan main structure and working principle is mainly composed of iron inlaid copper gate door frames, door rails, wedging means sealing surface and other components. 1, the main frame structure ⑴ whole cast made from cast iron, comes with guide grooves on both sides of the door, as the door and down the rail after finishing. Doorframe vertical plane through the planer and vehicle finishing and machining a groove, respectively, in order to insert into the bronze seal faces. ⑵ the door for the whole cast of square or round plate, and the positive side comes with "#" shape of the ribs, the ribs of the gate depending on the number and size specifications, generally spacing between 250-350mm, the doors of the plane Finishing with a set of copper strip slots to insert bronze seal surface on both sides of the door and the door frame side finishing groove with the formation of the upper and lower rails. Door top with lug, lug cast steel, door and hanging ears after two contact surfaces finishing bolted lug of pin hole boring processing. ⑶ use of cast iron rails, the rail surface processed into the same slot door and insert the bronze in the plane, to reduce friction when running up and down the door. Contact area connecting rails and door frame finishing with bolt connection, and a positioning pin to prevent dislocation. ⑷ wedge means: In order to achieve the sealing effect of the gate, on both sides of the gate settings wedge. Tin bronze wedges, and wedge bolts are fixed seats, seat milling grow hole wedge the door and door frame, easy to adjust wedge. When a gate is not good at sealing effect can be partially adjusted wedge, when the door is not closed in place or have not yet been put in place while the wedges wedge, the need to adjust all the wedges. ⑸ sealing surface copper strips or copper ring groove are inlay entry box and the door, and after sealing surface copper strip inlay good use Planer milling, grinding, ensuring close coordination between the door frame and the door. ⑹ trapezoidal thread screw made by the round, its accuracy 7e standard, thread length longer than the height of the door stroke 200mm, the gate is in the closed position, the threaded nut hoist beyond 50mm, screw total length of more than 5000mm, need for segmentation process, its joint use of round processed into the circular hole, and with round hinge bolts and fittings will screw fixation. Connector with fixed tooling process, and with the same specifications screw interchangeable. When the screw total length of more than 4000mm, the need for additional axis guides, shaft guide bushing made of cast iron pipe rack installation on the composition of the cast iron bracket, cast iron brackets to the wall, conduit bracket can be carried out in two directions adjust the lower screw welded round pin sets, connected by a pin and door. ⑺ all casting resin sand molding process, and the use of high-temperature tempering or aging. ⑻ door frames, door by Maximum Operating head design, the tensile, compressive and shear strength safety factor of not less than 5, the deflection is not greater than the length of the member 1/1500, rail tension, compression and shear strength of the safety factor not less than 5. ⑼ when the reverse pressure exceeds 3.0m, two-way gate. Biaxial compression gate structure, the main improvements were made from the following aspects: A gap in order to prevent reverse pressure on the door and the door frame is increased, especially to increase the upper and lower wedges, make sure the door body and the door seal gap ≤0.08 mm gap, the leakage control head at the maximum reverse leakage ≤2.5L / m.min, according to the number of upper and lower wedge gate size. B gate door structure also been adjusted, mainly on account of bearing pressure reverse pressure on the door body. Determine the structure adjustment is depending on gate size specifications. C to strengthen links with the wall of the gate strong, increasing the number of attachment bolts. Works gate hoist driven by the opening and closing nut is rotated at a trapezoidal thread screw driven action make running up and down the gate door, to cut off or clear the action of water.
