In actual design, due to certain deviations between the fire fighting working conditions and the design working conditions, the pressure reducing orifice plates with fixed apertures do not meet the design requirements, and it is necessary to adjust the aperture of the pressure reducing orifice plates. The adjustable pressure reducing orifice plates in the prior art cannot achieve real-time adaptive automatic adjustment according to the dynamic pressure of water flow.

[0014] The adaptive adjustable orifice plate assembly and the pipeline pressure reduction system provided by the present invention have the following beneficial effects:

[0015] The self - adaptive adjustable pressure - reducing orifice plate assembly provided by the present invention includes a rotating tray, a driving assembly, and a plurality of baffles. The driving assembly is used to drive the rotating tray to rotate. The plurality of baffles are arranged at intervals along the circumferential direction of the rotating tray, and each baffle is connected to a rotating shaft. Any two adjacent baffles partially overlap to enclose a pressure - reducing orifice. The plurality of baffles can rotate around the rotating shafts connected to them respectively as the rotating tray rotates, thereby changing the aperture of the pressure - reducing orifice. The driving assembly includes a baffle, an elastic member, and an infusion tube. The baffle is connected to the rotating tray, the baffle is connected to an elastic member. One end of the elastic member is connected to the baffle, and the other end of the elastic member is connected to a fixing member. The liquid outlet of the infusion tube faces the baffle. During the use of the self - adaptive adjustable pressure - reducing orifice plate assembly, the infusion tube is communicated with a conveying pipeline. The fluid in the conveying pipeline flows through the pressure - reducing orifice. The fluid in the conveying pipeline is pressured into the infusion tube and flows towards the port at one end of the infusion tube facing the baffle. And because the infusion tube 41 is flexibly connected to the baffle 14, the baffle can be pushed to drive the rotating tray to rotate. While the rotating tray rotates, it drives the baffles to rotate synchronously around the rotating shafts corresponding to the baffles respectively, thereby changing the aperture size of the pressure - reducing orifice and reducing the fluid pressure. However, due to the existence of the elastic member, during the process of the baffle being pushed, the elastic member generates elastic deformation and generates an elastic force opposite to the acting force of the fluid thrust. As the fluid pressure decreases, the elastic force will be greater than the thrust of the fluid acting on the baffle, driving the baffle to drive the rotating tray to rotate in the opposite direction, so that the aperture of the pressure - reducing orifice changes in the opposite direction again, realizing self - adaptive adjustment of pressure reduction.

The pipeline pressure - reducing system includes a conveying pipeline and any one of the above - mentioned self - adaptive adjustable pressure - reducing orifice plate assemblies. The fluid in the conveying pipeline flows through the pressure - reducing orifice, and the pipeline is communicated with the infusion tube. Since the pipeline pressure - reducing system includes any one of the above - mentioned self - adaptive adjustable pressure - reducing orifice plate assemblies, the pipeline pressure - reducing system can also realize self - adaptive adjustment of pressure reduction.

[0030] The object of the present invention is to provide an adaptive adjustable pressure-reducing orifice plate assembly and a pipeline pressure-reducing system, which are applied to a fluid pipeline to automatically adjust the aperture size of the pressure-reducing orifice according to the fluid pressure and achieve adaptive pressure reduction.

[0031] To solve the above technical problems, the present invention provides an adaptive adjustable pressure-reducing orifice plate assembly. Please refer to Figures 1 to 3 , Figure 1 is the front view of the adaptive adjustable pressure-reducing orifice plate assembly in the first state provided by an embodiment of the present invention; Figure 2 is the front view of the adaptive adjustable pressure-reducing orifice plate assembly in the second state provided by an embodiment of the present invention; Figure 3Schematic diagram of the setting relationship among the baffle, elastic member, fixing member and infusion tube of the adaptive adjustable pressure-reducing orifice plate assembly provided by an embodiment of the present invention. As Figures 1 to 3 shown, the adaptive adjustable pressure-reducing orifice plate assembly includes a rotating tray 1, a driving assembly and a plurality of baffles 2. The driving assembly is used to drive the rotating tray 1 to rotate; the plurality of baffles 2 are arranged at intervals along the circumference of the rotating tray 1, and each baffle 2 is connected to a rotating shaft 31; any two adjacent baffles 2 partially overlap to enclose a pressure-reducing orifice 20; the plurality of baffles 2 can rotate around the rotating shaft 31 connected thereto respectively as the rotating tray 1 rotates, so that the aperture of the pressure-reducing orifice 20 changes; the driving assembly includes a baffle 14, an elastic member 13 and an infusion tube 41. The baffle 14 is connected to the rotating tray 1, the baffle 14 is connected to an elastic member 13, one end of the elastic member 13 is connected to the baffle 14, the other end of the elastic member 13 is connected to a fixing member 42, the liquid outlet of the infusion tube 41 faces the baffle 14 and the infusion tube 41 is flexibly connected to the baffle 14. During the use of the adaptive adjustable pressure-reducing orifice plate assembly, the infusion tube 41 will be connected to a conveying pipeline 5, and the fluid in the conveying pipeline 5 flows through the pressure-reducing orifice 20. The fluid in the conveying pipeline 5 is pressured into the infusion tube 41 and flows towards one end of the infusion tube 41 facing the baffle 12. And because the infusion tube 41 is flexibly connected to the baffle 14, the baffle 12 can be pushed and then drive the rotating tray 1 to rotate. While the rotating tray 1 rotates, it drives the baffles 2 to rotate synchronously around the rotating shafts 31 corresponding to the baffles 2 respectively, so as to change the aperture of the pressure-reducing orifice 20 and reduce the fluid pressure. However, due to the existence of the elastic member 13, during the process of the baffle 12 being pushed, the elastic member 13 generates elastic deformation and generates an elastic force opposite to the acting force of the fluid thrust. As the fluid pressure decreases, the elastic force will be greater than the thrust of the fluid acting on the baffle 12, driving the baffle 12 to drive the rotating tray 1 to rotate in the opposite direction, so that the aperture of the pressure-reducing orifice 20 changes in the opposite direction again, and finally the force balance state of the baffle 12 is achieved, realizing adaptive adjustment of pressure reduction. The change in the aperture of the pressure-reducing orifice 20 can be compared and referenced Figure 1 with Figure 2 .

[0032] It should be understood that in order to realize the function of the adaptive adjustable pressure reducing orifice plate assembly, the rotating tray 1 should not block the pressure reducing orifice 20. The specific implementation methods include but are not limited to setting the rotating tray 1 as an annular disc coaxial with the pressure reducing orifice 20. Preferably, a plurality of the same-specification baffles 2 can be evenly arranged along the circumferential direction of the rotating tray 1. The baffles 2 can be made of materials such as stainless steel and can be customized with different thicknesses according to needs. When the baffles 2 rotate at different angles, the pressure reducing orifice 20 forms approximate circles with different diameters. The pressure reducing orifice 20 is basically circular and concentric with the pipeline. The pressure reduction values of different orifice diameters under the same flow rate can be calculated according to the hydraulic formula, which has strong basis in use to achieve the purpose of adjustable pressure reduction. The inventor found through a large number of experiments that when 6-8 baffles 2 of reasonable size are set, and the minimum diameter of the pressure reducing orifice 20 is not less than 30% of the inner diameter of the conveying pipeline 5, and the maximum diameter can be equal to the inner diameter of the conveying pipeline 5, better use effects can be obtained, but it is not limited thereto.

[0033] Please refer to Figure 3 , such as Figure 3 shown. In an exemplary embodiment, the elastic member 13 can be a spring. The spring can be perpendicularly connected to both the baffle 12 and the fixing member 42, or can be connected to the fixing member 42 through an arc-shaped column having the same rotation curvature as the rotating tray 1. The spring is sleeved on the arc-shaped column. The baffle 12 is provided with a hole adapted to the arc-shaped column. The baffle 12 can reciprocate on the arc-shaped column by using the hole, but the diameter of the hole is smaller than the inner diameter of the spring so that the spring can be connected to the baffle 12, thereby realizing the regular expansion and contraction of the spring and the calculability of the elastic force. In this scenario, the model and elastic parameters of the spring can be selected through experimental design to determine the pressure limit value of the fluid and customize the adjustment performance of the adaptive adjustable pressure reducing orifice plate assembly. The fluctuation of the upstream pressure will be reflected in the tightness of the spring in real time through the pressure change, achieving the effect of real-time pressure stability.

[0034] Please continue to refer to Figures 1 to 4 , Figure 4 is a cross-sectional view of the adaptive adjustable pressure reducing orifice plate assembly provided by an embodiment of the present invention applied to a pipeline pressure reducing system. As Figures 1 to 4As shown, in an exemplary embodiment, the implementation manner in which a plurality of the baffle plates 2 rotate synchronously around the rotating shafts 31 corresponding to the baffle plates 2 one by one according to the rotation of the rotating tray 1 is as follows: The self-adaptive adjustable pressure reducing orifice plate assembly further includes a first fixing plate 3, and the rotating shafts 31 are arranged on the first fixing plate 3. A plurality of the rotating shafts 31 are arranged on the surface of the first fixing plate 3, and each baffle plate 2 is rotatably connected to each rotating shaft 31 one by one. A first limiting slide rail 21 is arranged on each baffle plate 2, the first limiting slide rail 21 extends along the circumferential direction of the rotating tray, and a plurality of first limiting members 11 are arranged on the rotating tray 1. Each first limiting member 11 is arranged and adapted to each first limiting slide rail 21 one by one, and the first limiting member 11 can slide reciprocally in the first limiting slide rail 21, so that when the rotating tray 1 rotates around the axis of the rotating tray 1, each baffle plate 2 rotates synchronously around the rotating shaft 31. Thus, a plurality of the baffle plates 2 rotate synchronously around the rotating shafts 31 corresponding to the baffle plates 2 one by one according to the rotation of the rotating tray 1. It should be understood that preferably, the rotating shafts 31 are uniformly arranged along the circumferential direction of the first fixing plate 3, and the first limiting members 11 are uniformly arranged along the circumferential direction of the rotating tray 1 to cooperate with a plurality of the baffle plates 2 arranged uniformly along the circumferential direction of the rotating tray 1, but it is not limited thereto.

[0035] Please continue to refer to Figures 1 to 4 , as Figures 1 to 4 shown, preferably, the self-adaptive adjustable pressure reducing orifice plate assembly further includes a second fixing plate 4 (see Figure 4 ), the infusion tube 41 penetrates through the second fixing plate 4, and the fixing member 42 is arranged on the second fixing plate 4. In an exemplary embodiment, the first fixing plate 3 and the second fixing plate 4 form a housing surrounding the self-adaptive adjustable pressure reducing orifice plate assembly through connection with other components, so as to protect the components of the self-adaptive adjustable pressure reducing orifice plate assembly and provide fixed positions for the rotating shafts 31, the fixing member 42, and the infusion tube 41, but it is not limited thereto. It should be understood that in this scenario, to ensure that the fluid can push the baffle 12 when flowing through the infusion tube 41, thereby driving the rotating tray 1 to rotate, the infusion tube 41 should be set to be perpendicular to the baffle 12 and parallel to the rotating tray 1 after penetrating through the second fixing plate 4.

[0036] It should be understood that to achieve the function of the self-adaptive adjustable pressure reducing orifice plate assembly, neither the first fixing plate 3 nor the second fixing plate 4 blocks the pressure reducing orifice 20. The implementation manners include but are not limited to setting the first fixing plate 3 and the second fixing plate 4 as annular plates coaxial with the pressure reducing orifice 20, which will not be elaborated here.

[0037] Please continue to refer toFigure 4 , as Figure 4 shown, preferably, a valve 411 is provided on the infusion tube 41, and the adaptive adjustable orifice plate assembly can be converted into a manual control mode by closing the valve 411. In an exemplary embodiment, the implementation method of the manual control mode is as follows: the rotating tray 1 is in transmission connection with a first mechanical transmission member 51, and the rotating tray 1 rotates around the axis of the rotating tray 1 along with the movement of the first mechanical transmission member 51. The implementation manners of the transmission connection between the rotating tray 1 and the first mechanical transmission member 51 include but are not limited to mechanical transmissions such as gear transmission and rotating handle transmission. It should be understood that the first mechanical transmission member 51 should be arranged so as not to affect the restraint effect of the elastic member 13 in the adaptive adjustable orifice plate assembly, and the two can independently or cooperate to achieve the restraint effect in the adaptive adjustable orifice plate assembly, and the implementation manners include but are not limited to setting the first mechanical transmission member 51 as a detachable connection.

[0038] Furthermore, a scale member is provided on the first mechanical transmission member 51, and each scale on the scale member corresponds to a target aperture diameter. The scale member enables each state during the movement of the first mechanical transmission member 51 to correspond to a scale, and in this state, the pressure reducing orifice 20 correspondingly generates a target aperture diameter, and the scale and the target aperture diameter value are in one-to-one correspondence. Such a setting can achieve the control of the rotation of the rotating tray 1 according to the target aperture diameter. It should be understood that the implementation manner of the corresponding scale can be obtained through experiments during the manufacturing process of the adaptive adjustable orifice plate assembly, and the scale display includes but is not limited to any implementation manner of scale display such as a scale disk, a scale ruler, and an electronic scale display based on a variable resistor, which will not be elaborated here.

[0039] Optionally, the first mechanical transmission member 51 is in control connection with a first controller. Such a setting can achieve the remote control of the adaptive adjustable orifice plate assembly, and further facilitate the operation and use of the adaptive adjustable orifice plate assembly. It should be understood that the first controller includes but is not limited to motor devices provided with switches and adjustable variable resistors, which will not be elaborated here.

[0040] Please continue to refer to Figure 3, Preferably, a second limiting member 12 is provided on the rotating tray 1, and a second limiting slide rail 141 cooperating with the second limiting member 12 is provided on the baffle 14. The second limiting slide rail 141 extends along the radial direction of the rotating tray 1, and the second limiting member 12 can slide reciprocally in the second limiting slide rail 141. A sliding member extending along the outlet direction of the liquid infusion tube 41 and slidably connected to the liquid infusion tube 41 is provided on the tube wall of the liquid infusion tube 41, and the sliding member is connected to the baffle 14; or a third limiting slide rail 43 extending along the outlet direction of the liquid infusion tube 41 is provided on the second fixing plate 4 (see Figure 4 ), the baffle 14 cooperates with the third limiting slide rail 43, and the baffle 14 can slide reciprocally in the third limiting slide rail 43. It is arranged in this way so that when the fluid flows in the liquid infusion tube 41, the baffle 14 can only perform a linear reciprocating motion along the outlet direction of the liquid infusion tube 41 due to being restricted, while the rotating tray 1 can still rotate due to the restrictive action of the second limiting member 12 and the second limiting slide rail 141, thereby realizing the axial expansion and contraction of the elastic member 13, making the elastic force of the elastic member 13 measurable, and further guiding the adaptation of the elastic force of the elastic member 13 to the fluid pressure.

[0041] The present invention also provides a pipeline pressure reduction system. Please refer to Figure 5 , as Figure 5 shown, the pipeline pressure reduction system includes a conveying pipeline 5 and any one of the above-mentioned self-adaptive adjustable orifice plate assemblies. The fluid in the conveying pipeline 5 flows through the pressure reduction orifice 20, and the conveying pipeline 5 is communicated with the liquid infusion tube 41. Specifically, the pipeline is communicated with the end of the liquid infusion tube 41 that does not face the baffle 12. Since the pipeline pressure reduction system includes any one of the above-mentioned self-adaptive adjustable orifice plate assemblies, the pipeline pressure reduction system can also realize self-adaptive adjustment of pressure reduction and has all the advantages of the self-adaptive adjustable orifice plate assembly, which will not be elaborated here. It should be noted that the pipeline pressure reduction system can be installed between multiple pipelines, and the node connection method generally adopts flange or grooved connection. For small-diameter pipelines, thread or press connection can be adopted.

[0042] Please continue to refer to Figure 5 , as Figure 5 shown, further, the pipeline pressure reduction system further includes a pressure measuring device 52 for measuring the pressure of the fluid flowing through the conveying pipeline 5 to measure the pressure of the fluid flowing through the conveying pipeline 5 in real time. This can guide technicians to observe the fluid pressure in the conveying pipeline 5 and take corresponding adjustment measures. The pressure measuring device 52 includes but is not limited to any device that can measure fluid pressure such as a pressure gauge.

[0043] Further, the measuring device 52 is communicatively connected to a second controller, which is controllably connected to a second mechanical transmission member. The second mechanical transmission member is drivingly connected to the rotating tray 1, and the rotating tray 1 rotates about its axis along with the movement of the second mechanical transmission member. The second controller is configured with a preset pressure value range. The controller is configured to control the second mechanical transmission member to drive the rotating tray 1 to rotate until the pressure value of the measuring device 52 is within the preset pressure value range according to the pressure value signal transmitted by the measuring device 52. This setting can achieve automatic control of the fluid pressure in the conveying pipeline 5 and further improve the adaptive adjustment ability of the pipeline pressure reduction system. It should be understood that the second mechanical transmission member should be set so as not to affect the restraint effects of the elastic member 13 and the first mechanical transmission member 51 in the adaptive adjustable orifice plate assembly, and the three can achieve their restraint effects independently or in cooperation in the adaptive adjustable orifice plate assembly. In some exemplary embodiments, the first controller and the second controller can be the same controller, and the first mechanical transmission member 51 and the second mechanical transmission member can also be the same mechanical transmission member.
