But no matter how good a gate, if the device is not correct, it will not play a proper role. According to the planning of the equipment level, in the wall marked the export of vertical center line and the elevation of the line at the bottom of the gate. Error is not more than, + 10毫米) 。 Check whether door hanging hole center and hoist the reserved hole alignment. ( 1) To raise its gate in place to stand; ( 2) The gate hung on the wall, adjust the levelness of the door and straightness ( The levelness of the frame at the bottom of tank and side and straightness is not more than 1/1000) 。 With embedded steel plate and frame connected firmly. Secondary water use effective closed method, ensure no leakage between door frame and structure. ( 3) Equipment thrust screw and gate valve opening and closing, levelness and straightness in line with the planning requirements of the equipment. Opening and closing machine center and gate valve plate screw hole should be located in the same vertical line. Hoist and gate valve plate screw hole straightness error should be less than 1/1000 of the whole process of error should be less than 2 mm. Connected to the gate valve driver screw should be based on gate thrust screw gate end. Gate thrust screw straightening, opening and closing base are fixed. Ascension pad with iron frame. The secondary concrete pouring gate, opening and closing machine. ( 4) Check: gate device after the installation, should check the precision of the equipment, to meet the requirements of equipment fastener connection is firm; Check and add grease inside in the opening and closing machine; ( 2) Gate valve opening and closing test under anhydrous conditions. Smooth sensitive operation, action in place, screw rotation, door plank, kick, sound without jamming. ( 3) Below the planning level, gate opening and closing smoothly, without sudden jumps off phenomenon. Limit switch should be sensitive, accurate and reliable; ( 4) Assist supplier site in accordance with the relevant provisions of the leak test. In the largest planning under the condition of water level, gate leakage within the rules.
