The utility model discloses a resistance orifice plate device capable of being replaced on line. The resistance orifice plate device comprises a resistance pipe, the communicating shell extends in the radial direction of the resistance pipe, and the communicating shell is provided with an opening; and the pore plate assembly comprises a pore plate and a sealing plate, the pore plate can enter the resistance pipe through the opening and is arranged in the resistance pipe in a matched mode, the sealing plate is used for sealing the opening, and the sealing plate and the communicating shell can be locked through a locking piece. According to the utility model, the pore plate and the resistance pipe are not detachable into a whole. Therefore, when the resistance pore plate device is replaced, only the pore plate needs to be replaced, the resistance pipe does not need to be replaced, and shutdown is not needed. Under the condition of no shutdown, the sealing plate and the pore plate are moved upwards, so that the
