The transmission component 3 can be connected to the orifice plate 2 to drive its movement in the first direction. During use, the transmission component 3 can change the holes 20 connecting the equipment pipeline by driving the orifice plate 2, thereby adjusting the flow rate within the equipment pipeline.
[0034] Preferred, such as Figures 1 to 3As shown, in this embodiment, the main body 1 of the device can be approximately rectangular in shape. The main body 1 may include a detachably connected first half 101 and a second half 102, with a receiving cavity formed between the first half 101 and the second half 102. The first half 101 and the second half 102 can be interlocked to form the receiving cavity. More preferably, when the first half 101 and the second half 102 are interlocked, the contact surfaces of the first half 101 and the second half 102 can be parallel to the surface of the perforated plate 2. This arrangement makes it easier for the operator to observe the entire perforated plate 2 when the first half 101 and the second half 102 are disassembled, facilitating adjustments. Preferably, the first half 101 and the second half 102 can be connected by bolts or pins.
[0035] Preferred, such as Figures 1 to 3 As shown, in this embodiment, the receiving cavity may include a first receiving cavity 11. The first receiving cavity 11 may be formed in a strip shape; specifically, the shape of the first receiving cavity 11 may be approximately a cuboid. The length direction of the first receiving cavity 11 may be the first direction, to reserve sufficient movement space for the perforated plate 2. The perforated plate 2 may be a rectangular plate. The side edge in the width direction of the perforated plate 2 may abut against the side edge in the width direction of the first receiving cavity 11 to guide the movement of the perforated plate 2.
[0036] Further optimized, such as Figures 1 to 3 As shown, in this embodiment, a first annular groove and a second annular groove may be provided inside the main body 1 of the device. The first annular groove and the second annular groove may be respectively formed on both sides of the perforated plate 2, and the first annular groove and the second annular groove may be formed on the side wall of the first receiving cavity 11. Two washers 4 are respectively installed in the first annular groove and the second annular groove to fix the washers 4. The two washers 4 may abut against the two sides of the perforated plate 2 to prevent fluid leakage into the first receiving cavity 11.
[0037] Further optimized, such as Figures 1 to 3 As shown, in this embodiment, the first fluid channel 100 and the second fluid channel can be cylindrical channels, and the axial directions of the first fluid channel 100 and the second fluid channel can be perpendicular to the surface of the orifice plate 2. The first annular groove, the second annular groove, the first fluid channel 100, and the second fluid channel can be coaxially arranged to facilitate fluid flow. Furthermore, the diameter of the first annular groove is larger than the orifice diameter of the first fluid channel 100, and the diameter of the second annular groove is larger than the orifice diameter of the second fluid channel. The diameters of the first annular groove and the second annular groove can be equal and larger than the orifice diameter of any of the holes 20.
[0038] Preferred, such as Figures 1 to 3 In this embodiment, the receiving cavity may further include a second receiving cavity 12, specifically, the second receiving cavity 12 is cylindrical. The length direction of the second receiving cavity 12 can be a first direction. A limiting block 5 can be movably disposed within the second receiving cavity 12. The limiting block 5 can move synchronously with the perforated plate 2, that is, the limiting block 5 reciprocates within the second receiving cavity 12 along the first direction. When the limiting block 5 moves to a preset position, the first fluid channel 100 and the second fluid channel are connected through one of the holes 20 on the perforated plate 2, at which time the hole 20 moves between the two washers 4.
[0039] Furthermore, preferably, such as Figure 1 and Figure 2 In this embodiment, the transmission component 3 can be a cylindrical rod. A through hole for the transmission component 3 to pass through can be provided between the first receiving cavity 11 and the second receiving cavity 12. The transmission component 3 can pass through the first receiving cavity 11 and the second receiving cavity 12 along a first direction. The end of the transmission component 3 can be connected to the end of the perforated plate 2 to drive the perforated plate 2 to reciprocate along the first direction. The limiting block 5 can be a cylindrical component. The transmission component 3 can pass through the limiting block 5 along its axis and be fixedly connected to the limiting block 5 to drive the limiting block 5 and the perforated plate 2 to move synchronously. In addition, the circumferential surface of the limiting block 5 can contact the inner wall surface of the second receiving cavity 12 to provide guidance for the movement of the limiting block 5.
[0040] Preferred, such as Figures 1 to 3 In this embodiment, the online orifice plate replacement device may further include a drive unit located outside the device body 1. A transmission component 3 may partially extend from the device body 1 and be connected to the drive unit. The drive unit is capable of driving the transmission component 3 to move along a first direction.
[0041] like Figures 1 to 3 In one embodiment, the driving unit may be used solely to drive the transmission component 3. The driving unit may be manually operated, or it may be a linear motor, cylinder, etc. In this case, the number of holes 20 on the perforated plate 2 may be two or three. The number of preset positions is equal to the number of holes 20. A spring 6 may also be provided inside the second receiving cavity 12, and the spring 6 is connected to the first end of the second receiving cavity 12 (which may be, for example,...). Figure 2 (shown on the left end) and limit block 5.
[0042] During use, when no force is applied by the driving unit, the spring 6 is in its initial state (neither extended nor compressed), and the limiting block 5 is in its initial position. When the driving unit applies a pulling force, the limiting block 5 compresses the spring 6 to its limit. When the driving unit applies a pushing force, the spring 6 extends, and the limiting block 5 moves to the second end of the second receiving cavity 12 (which can be as follows). Figure 2 (As shown on the right end). In the above three states, the position of the limiting block 5 is the preset position, corresponding to the three holes 20 on the perforated plate 2. That is, when the spring 6 is compressed to its limit, the hole 20 away from the second receiving part moves between the two washers 4; when the spring 6 is in the initial state, the middle hole 20 is located between the two washers 4; when the limiting block 5 moves to the second end of the second receiving cavity 12, the hole 20 near the second receiving part moves between the two washers 4, thereby enabling the limiting block 5 to position the holes 20 on the perforated plate 2. When there are two holes 20 on the perforated plate 2, the preset position can be selected from two of the above three preset positions.
[0043] Not limited to this, in another embodiment, the drive unit can drive the transmission component 3 to move a preset distance along a first direction. The drive unit can be a graduated knob or a servo motor, etc. In this case, the number of holes 20 on the perforated plate 2 can be greater than three. The operator can set multiple preset distances to correspond to the positions of multiple holes 20.
[0044] In addition, preferred, such as Figure 2 As shown, in this embodiment, the diameter of the plurality of holes 20 on the orifice plate 2 can gradually increase from one end to the other. This arrangement makes it easy for operators to adjust the flow rate of the equipment pipeline.
[0045] The online orifice plate replacement device enables the online replacement of the orifice plate 2 during operation. It can adjust the size of the orifice 20 connecting the equipment pipeline in real time without disassembling the equipment pipeline, thereby regulating the flow rate of the fluid in the equipment pipeline. The online orifice plate replacement device significantly improves the working efficiency of the equipment while effectively reducing the labor intensity of the operators.
