Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard is a revision of CJ/T 3029-1994 "Adjustable Tricks (hole width 300~5000mm)", the date of implementation of this standard Since then, CJ/T 3029-1994 has been abolished. The main technical changes in this standard compared with CJ/T 3029-1994 are as follows.

--- Added terms and definitions (see 3.1, 3.2, 3.3);

--- Increased the requirements for the operation mode, sealing method and transmission mode, and increased the requirements for the model representation method (see 4.1, 4.2);

---Modified the maximum forward and reverse design pressure values of adjustable slamming doors (see Table 1 of 5.2, 1994 edition);

--- Revised the materials of the main components of the adjustable slamming door (see Table 2, Table 3 of the 1994 edition);

--- Increased material requirements for hard and soft seals (see 6.3);

--- Added technical requirements for rotary adjustable tricks (see 7.2.1.2, 7.2.1.3, 7.5.5);

--- Increased gasket requirements in grease environments (see 7.2.1.4);

---Modified part of the door frame and door panel requirements (see 7.2.1 and 7.2.2, 1994 editions 4.3.1 and 4.3.2);

---Modified the requirements for the contact surface between the guide rail and the door frame (see 7.2.3.1, 4.3.3.2 of the 1994 edition);

--- Increased the requirements for locking devices (see 7.2.4);

--- Increased the requirements for lifting lugs, screw and connecting parts, screw guides (see 7.2.5, 7.2.6, 7.2.7);

--- Increased the requirements of the hoist rated output torque, rated power, handwheel, handle and opening position indicator (see 7.2.8.3, 7.2.8.4, 7.2.8.5);

--- Increased the total thickness of the paint film in the environment containing chloride ions (see 7.4.4);

--- Increased the requirements for soft seal compression (see 7.5.2);

--- Revised the requirements for the level of adjustment of the adjustable jaw (see 7.5.4, 4.3.7.1 of the 1994 edition);

--- Increased leakage requirements for adjustable slamming doors under different conditions (see 7.5.8, 5.3 of 1994).
