[0003] The purpose of this invention is to provide a modular adjustable coke oven gas pipeline orifice plate box for convenient and rapid adjustment of gas flow.

[0004] To achieve the aforementioned objectives of this utility model, the modular adjustable coke oven gas pipeline orifice plate box of this utility model adopts the following technical solution:

[0005] A modular adjustable coke oven gas pipeline orifice plate box includes a box body with pipes fixedly connected to both ends of the box body, and the pipes are connected to the gas pipeline. The box body has gas passage holes, and orifice plate modules are inserted into the positions of the gas passage holes. The orifice plate modules include multiple orifice plates arranged concentrically, with adjacent orifice plates in contact. The orifice plates are annular, with a gas flow hole at the center of the orifice plate, and the diameter of the gas flow hole of the multiple orifice plates decreases sequentially. The orifice plate is provided with a displacement component to drive its displacement. A box cover is provided on one side of the box body. The displacement component includes a pull rod that is movably inserted through the box cover. One end of the pull rod extends into the box body and is connected to the orifice plate, and the other end of the pull rod extends out of the box body and is provided with a handle. The pull rod is provided with a mounting rod arranged inside the box body, and a spring is provided on the outer periphery of the pull rod between the mounting rod and the box cover. A nut is provided on the pull rod outside the box body, and the pull rod has an external thread that matches the nut.

[0006] Preferably, a limiting part is provided between two adjacent perforated plates. The limiting part is a limiting block provided on one of the perforated plates, and the limiting block contacts the outer diameter side of the other adjacent perforated plate. By setting the limiting block, the position of the perforated plates is limited, ensuring that the perforated plates are arranged concentrically.

[0007] Preferably, the inner wall of the box is provided with a limiting groove, which is arc-shaped, and the largest diameter perforated plate is inserted into the limiting groove to achieve limiting. The limiting groove ensures the insertion position of the largest diameter perforated plate.

[0008] Preferably, the housing is provided with guide grooves for displacing the perforated plates. Multiple guide grooves are provided, each corresponding to one perforated plate. The outer diameters of the multiple perforated plates decrease sequentially, with the largest diameter perforated plate inserted into one of the guide grooves. Other perforated plates are provided with guide blocks for inserting into other guide grooves. The guide grooves guide the position of the perforated plates, ensuring that the perforated plates move linearly along the housing.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This utility model features a modular orifice plate module comprising multiple orifice plates arranged concentrically, with the diameter of the airflow holes decreasing sequentially. Therefore, after selecting a suitable airflow hole as needed, the other orifice plates covering that airflow hole are driven to move. During movement, the orifice plates are simply moved by pulling a rod and then tightened with a nut. The orifice plates do not need to be removed or replaced, allowing for convenient and rapid adjustment of gas flow. The structure is simple and practical. Attached Figure Description

After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0018] like Figure 1-5As shown, a modular adjustable coke oven gas pipeline orifice plate box includes a box body 1, with pipes 14 fixedly connected to both ends of the box body 1, and the pipes 14 connected to the gas pipeline; the box body 1 is provided with a gas passage hole 15, and an orifice plate module is inserted at the position of the gas passage hole 15; the orifice plate module includes multiple orifice plates 2 arranged concentrically, with two adjacent orifice plates 2 in contact; the orifice plate 2 is set as annular, and a gas flow hole 9 is provided at the center of the orifice plate 2, with the diameter of the gas flow hole 9 of the multiple orifice plates 2 decreasing sequentially; a limiting part is provided between two adjacent orifice plates 2, the limiting part being a limiting block 11 set on one of the orifice plates 2, the limiting block 11 contacting the outer diameter side of the other adjacent orifice plate 2; the inner wall of the box body 1 is provided with a limiting groove 13, the limiting groove 13 is set as arc, and the orifice plate 2 with the largest diameter is inserted into the limiting groove 13 to achieve limiting; The perforated plate 2 is equipped with a displacement assembly to drive its displacement. A box cover 5 is provided on one side of the box body 1. The displacement assembly includes a pull rod 3 that is movably inserted through the box cover 5. One end of the pull rod 3 extends into the box body 1 and is connected to the perforated plate 2. The other end of the pull rod 3 extends out of the box body 1 and is equipped with a handle 6. The pull rod 3 is equipped with an installation rod 12 arranged inside the box body 1. A spring 4 is provided on the outer periphery of the pull rod 3 between the installation rod 12 and the box cover 5. A nut 7 is provided on the pull rod 3 outside the box body 1. The pull rod 3 is equipped with an external thread that matches the nut 7. The box body 1 is equipped with a guide groove 8 for displacing and guiding the perforated plate 2. Multiple guide grooves 8 are provided, and each guide groove 8 corresponds to guiding one perforated plate 2. The outer diameters of the multiple perforated plates 2 decrease sequentially. The perforated plate 2 with the largest diameter is inserted into one of the guide grooves 8. Other perforated plates 2 are equipped with guide blocks 10 for inserting other guide grooves 8.

[0019] The specific working process and principle of this utility model are as follows: After the connecting pipe 14 is connected to the gas pipeline, the gas flow rate is adjusted as needed. When it is necessary to increase the gas flow rate, gas is introduced through the gas flow hole 9 with a larger diameter. Then, the other orifice plates 2 that block the gas flow hole 9 are moved by the pull rod 3. After being moved to the appropriate position, the nut 7 is screwed on to lock it. When it is necessary to reduce the gas flow rate, the other orifice plates 2 that have been moved away are reset. At this time, the corresponding nut 7 is loosened, and the elastic potential energy of the compressed spring 4 is released. Under the action of the spring 4, the orifice plate 2 is driven to move to the position directly opposite the gas flow hole 15. Furthermore, the orifice plate 2 contacts and is limited by the limiting block 11 on the adjacent orifice plate 2. Therefore, according to the combination of different orifice plates 2, the diameter of the gas flow hole 9 for introducing gas is different, thereby realizing the adjustment of the gas flow rate.
