Description

Technical Field

[0001] The invention belongs to the technical field of flow meters, in particular to an intelligent balanced adjustment flow meter. Background Art

[0002] The intelligent balanced adjustment flowmeter is a new type of differential pressure flowmeter. It inherits the advantages of the traditional differential pressure flowmeter, which is simple, safe, reliable and easy to maintain. A throttling element is set in the flowmeter based on the principle of fluid mechanics, and the pressure difference before and after the fluid passes through the throttling element is measured respectively. The built-in chip calculates the flow rate of the fluid in the pipeline through the Bernoulli equation.

[0003] In the prior art, a Chinese patent discloses a compact intelligent integrated RC adjustable flow meter (publication number: CN211042337U), whose main structure includes a flow tube, a throttle plate for throttling the fluid is arranged in the flow tube, a throttle hole for facilitating the passage of the fluid is opened on the throttle plate, and two pressure-taking tubes connected to the inside of the flow tube are arranged on the outer peripheral surface of the flow tube, and the two pressure-taking tubes are respectively located on both sides of the throttle plate, and a pressure gauge is commonly arranged at the ends of the two pressure-taking tubes; clamping flanges for clamping and fixing the flow tube to the measured pipeline are arranged at both ends of the flow tube, and a pair of centering rings are coaxially fixedly connected to the two end faces of the flow tube facing the clamping flange, and a centering groove for accommodating the centering ring is coaxially fixedly connected to the end face of the corresponding clamping flange facing the throttling member.

[0004] In actual use, the above patent uses the mutual locking of the centering ring and the centering groove to make the clamping flange coaxial with the flow tube, which is convenient for the installation of the staff, and the limiting of the protective tube by the limit clamp improves the stability of the installation. However, there are still corresponding disadvantages in actual use: when liquid begins to flow into the pipeline, the pressure in the pipeline increases, and the liquid flow will impact the pipeline to produce water hammer phenomenon (water flow shock wave). The water hammer phenomenon can be extremely destructive and can easily cause rupture at the connection between the flow tube and the measured pipeline, and the flow meter is damaged. When using the above patent, it is not easy to weaken the water hammer phenomenon and the impact destructive force on the connection, which reduces the practicality of the device.

[0020] Beneficial Effects

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention adopts the coordinated design of structures such as a connecting pipe, a diverter plate, a first installation cavity, a second installation cavity, and an elimination mechanism. When the liquid starts to flow from the right side to the left side of the connecting pipe in the pipeline, the thrust of the liquid flow pushes the impeller to move to the left, and the sealing plate is driven to flip through the connecting component. The liquid enters between the two installation plates through the liquid inlet channel, and then the liquid flows into the annular contraction airbag, which can disperse the impact force of the liquid on the connection between the connecting pipe and the pipeline, reduce the damage to the connecting pipe and the pipeline, weaken the water hammer phenomenon, and improve the practicality of the equipment. It solves the problem in the prior art that when the liquid starts to flow into the pipeline, the pressure in the pipeline increases, and the liquid flow will impact the pipeline to produce a water hammer phenomenon (water flow shock wave). The water hammer phenomenon can be extremely destructive and easily cause the connection between the flow tube and the measured pipeline to rupture, and the flow meter is damaged. When the above patent is used, it is not convenient to weaken the water hammer phenomenon and the impact destructive force on the connection, which reduces the practicality of the device.

[0023] 2. The present invention adopts the coordinated design of the annular shrinkable airbag, the first installation cavity, the annular spring plate, the detection mechanism and other structures. When liquid flows into the annular shrinkable airbag, the annular shrinkable airbag can be expanded, and the annular spring plate can be flipped. When the annular spring plate flips, the air delivery mechanism is driven to input air into the annular air groove. When the annular shrinkable airbag expands, the annular shell is driven to move. The movement of the annular shell drives the first annular docking plate to contact and squeeze the second annular docking plate. The second annular docking plate squeezes the air in the annular air groove. The air in the annular air groove squeezes the sealing gasket in the annular sealing groove through the vent hole. When When the sealing is poor and there is leakage, the second annular docking plate is squeezed and moves into the annular air groove, so that the sliding resistor slides outward on the surface of the resistor ring under the elastic force of the spring seat, which increases the generated resistance. When the sealing is leak-free, the first annular docking plate and the second annular docking plate are squeezed, causing the sliding resistor to slide inward on the surface of the resistor ring, which increases the generated resistance. The resistance change value is monitored by a resistance detector and the signal is sent to an external control system, thereby realizing the detection of the sealing gasket's sealing performance, solving the problem of inconvenience in accurately detecting the sealing performance of the sealing gasket in the prior art.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 11As shown, the present invention provides an intelligent balanced adjustment flow meter, including a connecting pipe 1, a connecting pipe 1, a diverter plate 2 is fixedly installed in the middle of the inner cavity of the connecting pipe 1, an intelligent pressure gauge 3 for measuring the liquid pressure on both sides of the diverter plate 2 is fixedly installed on the upper part of the outer surface of the connecting pipe 1, a first installation cavity 4 is opened between the outer ring wall and the inner ring wall of the connecting pipe 1, a second installation cavity 5 is opened between the left and right side walls of the diverter plate 2, and an elimination mechanism 6 for weakening water hammer impact is arranged in the first installation cavity 4 and the second installation cavity 5, two annular sealing grooves 7 are symmetrically opened on the left and right side walls of the connecting pipe 1, and a matching sealing gasket 8 is arranged in the inner cavity of the annular sealing groove 7; wherein, the inner cavity of the first installation cavity 4 is connected with the inner cavity of the second installation cavity 5, four diverter holes are symmetrically opened on the diverter plate 2, and the intelligent pressure gauge 3 is a prior art, and its structure and principle are not repeated here;

[0038] When in use, the connecting pipe 1 is placed between the two pipelines so that the sealing gasket 8 placed in the annular sealing groove 7 fits with the joint of the pipelines, and the flange connecting the two pipelines is fixed to the connecting pipe 1 by screws and nuts. The liquid flows from the right pipeline to the left pipeline, and the liquid is diverted and balanced through the diversion hole. The liquid flow on both sides of the diversion plate 2 is measured by the intelligent pressure gauge 3.

[0039] The elimination mechanism 6 includes two mounting plates 61 fixed on the left and right sides of the inner cavity of the second mounting cavity 5, an annular spring plate 62 arranged at the edges of the opposite surfaces of the mounting plates 61, an annular shrink airbag 63 arranged on the opposite sides of the two annular spring plates 62, and the outer ring of the annular shrink airbag 63 extends into the inner cavity of the first mounting cavity 4, a mounting channel 64 provided at the center of the right side wall of the diverter plate 2, four liquid inlet channels 65 equidistantly provided in the inner cavity of the mounting channel 64 in the circumferential direction, a sealing plate 66 installed in the inner cavity of the liquid inlet channel 65 by rotating the shaft, a liquid discharge mechanism 9 provided in the inner cavity of the annular shrink airbag 63, an impeller 67 provided on the right side of the mounting channel 64, a connecting assembly 10 provided on the left side wall of the impeller 67 for connecting the sealing plate 66, and a detection mechanism 11 symmetrically provided at the outer edges of the left and right side walls of the annular shrink airbag 63 for detecting the sealing performance of the sealing gasket 8;

[0040] Among them, the middle parts of the opposite back surfaces of the two annular spring plates 62 are fixedly connected to the opposite surfaces of the two mounting plates 61 respectively, the inner circle of the annular shrinkable airbag 63 is provided with an annular opening 68 connected to the inner cavity, the inner cavity of the annular opening 68 is fixedly connected to the side wall of the annular spring plate 62, and the middle part of the outer circle of the annular shrinkable airbag 63 is fixedly sleeved with a connecting ring, and the outer circle wall of the connecting ring is fixedly connected to the inner cavity of the first mounting cavity 4.

[0041] During use, when the liquid starts to flow from the right side to the left side of the connecting pipe 1 in the pipeline, the thrust of the liquid flow pushes the impeller 67 to move to the left, and drives the sealing plate 66 to flip through the connecting component 10. The liquid enters between the two mounting plates 61 through the liquid inlet channel 65, and then the liquid flows into the annular shrinkage airbag 63, which can disperse the impact force of the liquid on the connection between the connecting pipe 1 and the pipeline, reduce the damage to the connecting pipe 1 and the pipeline, and the liquid pushes the two annular spring plates 62 to flip during the influx process. The two annular spring plates 62 interact with the liquid to reduce the impact force of the liquid influx, which is convenient for protecting the annular shrinkage airbag 63.

[0042] It should be noted that the liquid flowing into the annular shrinkable airbag 63 can cause the annular shrinkable airbag 63 to expand. After the annular shrinkable airbag 63 expands, it can drive the detection mechanism 11 to operate. The detection mechanism 11 can detect the sealing performance of the sealing gasket 8 with high detection accuracy, which solves the problem that the prior art is not convenient for accurate detection of the sealing performance of the sealing gasket 8.

[0043] like Figure 8 and Fig. 9 As shown, the discharge mechanism 9 includes a mounting shell 91 transversely arranged at the center of the inner circle of the annular contraction airbag 63, a spiral rod 92 movably mounted on the left side of the inner cavity of the mounting shell 91 through a bearing, a transmission rod 93 slidably mounted at the center of the right end surface of the spiral rod 92, a liquid inlet hole 94 opened on the left side of the outer surface of the transmission rod 93, a liquid outlet hole 95 opened on the right side of the outer surface of the transmission rod 93, four liquid discharge pipes 96 fixedly mounted on the outer surface of the mounting shell 91 at equal intervals in the circumferential direction, and two communication holes 97 symmetrically opened on the left and right sides of the outer surface of the liquid discharge pipe 96;

[0044] Among them, the inner cavity of the connecting hole 97 is connected with the inner cavity of the drain pipe 96, one end of the drain pipe 96 is fixedly connected with the inner cavity of the annular contraction airbag 63, the inner cavity of the drain pipe 96 is connected with the inner cavity of the mounting shell 91, the liquid inlet hole 94 is connected with the liquid outlet hole 95 through a connecting channel 99 opened on the transmission rod 93, the right end of the transmission rod 93 passes through the outside of the inner cavity of the mounting shell 91, and the right end of the transmission rod 93 is fixedly connected to the center of the left side wall of the impeller 67, the bottom surface of the sealing plate 66 is movably connected to the outer surface of the mounting shell 91, a sliding groove is opened on the right end face of the spiral rod 92, the left end of the transmission rod 93 is slidably connected to the inner cavity of the sliding groove, a compression spring 98 is fixedly installed on the left side of the inner cavity of the sliding groove, and the right end of the compression spring 98 is fixedly connected to the left end of the transmission rod 93.

[0045] When in use, the flow of liquid drives the impeller 67 to rotate. When the impeller 67 rotates, the transmission rod 93 drives the screw rod 92 to rotate. When the screw rod 92 rotates, the liquid in the annular contraction airbag 63 can be transported to the right side of the inner cavity of the mounting shell 91 through the discharge pipe 96 and the connecting hole 97. Then the liquid enters the connecting channel 99 through the liquid inlet hole 94, and then the liquid in the annular contraction airbag 63 can be discharged through the liquid outlet hole 95. The liquid in the annular contraction airbag 63 can be discharged in time to prevent impurities in the liquid from accumulating in the annular contraction airbag 63 and causing damage to the annular contraction airbag 63.

[0046] like Figure 8 As shown, the connection assembly 10 includes an annular connection plate 101 rotating on the left side wall of the impeller 67 and four connection rods 102 circumferentially equidistantly hinged to the left side wall of the annular connection plate 101; wherein the left end of the connection rod 102 is hinged to the right side wall of the sealing plate 66.

[0047] When in use, when the impeller 67 moves to the left due to the impact force of the liquid flow, the impeller 67 moves to drive the annular connecting plate 101 to drive the connecting rod 102 to move. The movement of the connecting rod 102 can drive the sealing plate 66 to flip open. After the sealing plate 66 flips open to a certain angle, it can guide the incoming liquid.

[0048] like Fig.11 As shown, the detection mechanism 11 includes an annular shell 111 fixedly mounted on the edge of the side wall of the annular shrinkable airbag 63, a resistor ring 112 fixed on one side of the inner cavity of the annular shell 111, a sliding resistor 113 slidably sleeved on the outer surface of the resistor ring 112, a first annular docking plate 114 arranged between the outer surface of the annular shell 111 and the inner cavity of the first installation cavity 4, an annular air groove 115 provided on one side of the inner cavity of the first installation cavity 4, a second annular docking plate 116 movable left and right in the inner seal of the annular air groove 115, vent holes 117 equidistantly provided in the inner cavity of the annular air groove 115 for connecting to the annular sealing groove 7, a resistor detector 118 fixed in the inner cavity of the annular shell 111, and an air supply mechanism 12 arranged between the outer surface of the annular shrinkable airbag 63 and the side wall of the mounting plate 61 for supplying air to the annular air groove 115;

[0049] Among them, the resistance detector 118 has a built-in power supply and a wireless signal generating module, which can wirelessly transmit the detected resistance value to an external operation control system. The resistance detector 118 is a prior art, and its structure and principle are no longer repeated here. The resistance ring 112 and the sliding resistor 113 are electrically connected to the resistance detector 118 through wires respectively, and a group of support rods are fixedly installed on the side wall of the sliding resistor 113 at equal intervals in the circumference. One end of the support rod passes through the inner cavity of the annular shell 111 for fixed connection with the side wall of the first annular docking plate 114. One side wall of the first annular docking plate 114 is movably connected to one side wall of the second annular docking plate 116. A group of spring seats are fixedly installed on the inner cavity of the annular shell 111 away from the first annular docking plate 114 at equal intervals in the circumference, and the output end of the spring seat is fixedly connected to the side wall of the sliding resistor 113.

[0050] When in use, liquid flows into the annular shrinkable airbag 63, which can expand the annular shrinkable airbag 63 and flip the annular spring plate 62. When the annular spring plate 62 flips, it drives the air delivery mechanism 12 to input air into the annular air groove 115, and when the annular shrinkable airbag 63 expands, it drives the annular shell 111 to move. The movement of the annular shell 111 drives the first annular docking plate 114 to contact and squeeze the second annular docking plate 116. The second annular docking plate 116 squeezes the air in the annular air groove 115. The air in the annular air groove 115 squeezes the sealing gasket 8 in the annular sealing groove 7 through the vent hole 117. When the sealing is poor and there is leakage, the second annular docking plate 116 is squeezed and moves into the annular air groove 115, so that the sliding resistor 113 slides outward on the surface of the resistance ring 112 under the elastic force of the spring seat, which increases the generated resistance. When the sealing is leak-free, the first annular docking plate 114 and the second annular docking plate 116 are squeezed, so that the sliding resistor 113 slides inward on the surface of the resistance ring 112, which increases the generated resistance. The resistance change value is monitored by the resistance detector 118 and the signal is sent to the external control system, so that the sealing gasket 8 can be tested for sealing.

[0051] like Fig.10 As shown, the air delivery mechanism 12 includes an air delivery airbag 121 arranged between the outer surface of the annular shrinkable airbag 63 and the side wall of the mounting plate 61, and a hose 122 for connecting the air delivery airbag 121 and the annular gas groove 115; wherein, one side wall of the air delivery airbag 121 is fixedly connected to the side wall of the mounting plate 61, and the other side wall of the air delivery airbag 121 is fixedly connected to the side wall of the annular shrinkable airbag 63, and two assembly channels 13 are symmetrically arranged on the left and right sides of the outer circle of the annular shrinkable airbag 63, and two pressure measuring tubes are connected to the left and right sides of the intelligent pressure gauge 3, the lower end of the pressure measuring tube passes through the assembly channel 13, and the bottom end of the pressure measuring tube extends to the inner circle of the connecting tube 1, and the hose 122 passes through the inner cavity of the pressure measuring tube horizontally.

[0052] When in use, when the annular spring plate 62 turns over, it can squeeze the air delivery bag 121 , so that the air in the air delivery bag 121 enters the annular air groove 115 through the hose 122 .

[0053] The working principle and use process of the present invention:

[0054] When in use, first place the connecting pipe 1 between the two pipelines, so that the sealing gasket 8 placed in the annular sealing groove 7 fits with the butt joint of the pipeline, and fix the flange connecting the two pipelines to the connecting pipe 1 by screws and nuts. The liquid flows from the right pipeline to the left pipeline, and the liquid is diverted and balanced through the diversion hole. The liquid flow on both sides of the diversion plate 2 is measured by the intelligent pressure gauge 3. When the liquid starts to flow from the right side to the left side of the connecting pipe 1 in the pipeline, the thrust of the liquid flow pushes the impeller 67 to move to the left, and the impeller 67 moves to drive the annular connecting plate 101 to drive the connecting rod 102 to move. The movement of the connecting rod 102 can drive the sealing plate 66 to flip open, and the liquid The liquid flows into the annular shrinkable airbag 63, which can disperse the impact force of the liquid on the connection between the connecting pipe 1 and the pipeline, thereby reducing the damage to the connecting pipe 1 and the pipeline. The inflowing liquid can expand the annular shrinkable airbag 63 and flip the annular spring plate 62. When the annular spring plate 62 flips, it squeezes the air delivery airbag 121, so that the air in the air delivery airbag 121 enters the annular air groove 115 through the hose 122. When the annular shrinkable airbag 63 expands, it drives the annular shell 111 to move. The movement of the annular shell 111 drives the first annular docking plate 114 to contact and squeeze the second annular docking plate 116. The second annular docking plate 116 squeezes the air in the annular air groove 115. The air in the annular air groove 115 is squeezed through the vent hole 117 to squeeze the sealing gasket 8 in the annular sealing groove 7. When the sealing is poor and there is leakage, the second annular docking plate 116 is squeezed and moves into the annular air groove 115, so that the sliding resistor 113 slides outward on the surface of the resistance ring 112 under the elastic force of the spring seat, which increases the generated resistance. When the sealing is good and there is no leakage, the first annular docking plate 114 and the second annular docking plate 116 are squeezed, so that the sliding resistor 113 slides inward on the surface of the resistance ring 112, which increases the generated resistance. The resistance detector 118 monitors the resistance change value and sends a signal. In the external control system, the sealing performance of the sealing gasket 8 can be detected. At the same time, the flow of liquid drives the impeller 67 to rotate. When the impeller 67 rotates, the transmission rod 93 drives the screw rod 92 to rotate. When the screw rod 92 rotates, the liquid in the annular shrinkage airbag 63 can be transported to the right side of the inner cavity of the mounting shell 91 through the discharge pipe 96 and the connecting hole 97. Then the liquid enters the connecting channel 99 through the liquid inlet hole 94, and then the liquid in the annular shrinkage airbag 63 can be discharged through the liquid outlet hole 95.
