Two-way cast iron gate
Two-way cast iron gate

1. The surface of the door frame joining the wall gate and the wall should be flat. 2. Any outer side of the door frame (including the guide rail) should be machined with a vertical line parallel to and through the guide rail as the reference for the device gate. 3. Guide rail 4. The guide rail should be planned according to the large operating head, and the safety factor of its tensile, contraction and shear strength is not less than 5. When the door panel is opened to a high position, the top of the guide rail should be higher than the horizontal center line of the door panel. 5. The guide rail can be connected with the door frame by bolts (screws), or cast integrally with the door frame. 6. Seal seat 7. The seal seat should be separately placed on the machined door frame and door panel in the corresponding position, and fastened with countersunk screws made of the same material as the seal seat. In the process of opening and closing the door panel, it cannot be deformed or loosened. The head of the screw and the working surface of the sealing seat are finished together, and the surface roughness is not more than 3.2μm. 8. The working surface of the sealing seat shall not have defects such as scratches, cracks and pores. 9. The plate thickness of the sealing seat should meet the requirements of Table 4. 10. Lifting ears or lifting block nuts 11. Lifting ears or lifting block nuts should be provided on the upper end of the door panel to connect with the door pole. The stress point of the lifting lug or lifting block nut is as close as possible to the vertical line of the center of gravity of the door panel. When opening and closing the large working head, the safety factor of its tensile, contraction and shear strength is not less than 5. 12. The lifting lugs can be integrally cast with the door panel or connected with the door panel by bolts (screws). 13. A water-stop gasket should be provided between the wall-pipe gate and the wall pipe connection, and the gasket should meet the requirements of GB 4216.9 and GB 4216.10.
