[0044] Valve flow test device, including:

[0045] A connecting pipe 1, both ends of the connecting pipe 1 are fixedly connected with connecting rings 102, and a flow detector body 104 is provided on the circumferential surface of the connecting pipe 1, and plug-in rings 103 are movably inserted in the two connecting rings 102, and one end of the two plug-in rings 103 is fixedly connected with the pipeline 101;

[0046] A driving shaft 109, the driving shaft 109 is rotatably connected to the circumferential inner wall of the connecting pipe 1, and the upper end of the driving shaft 109 movably penetrates the circumferential surface of the connecting pipe 1 and extends outward;

[0047] Two first water wheels 4, both of which are fixedly connected to the circumferential surface of the screw rod 401;

[0048] A separation drive mechanism, which is disposed on the lower side of the screw rod 401;

[0049] The telescopic rod 402 is rotatably connected to the circumferential inner wall of the connecting tube 1, and the lower end of the telescopic rod 402 movably penetrates the circumferential surface of the connecting tube 1 and extends outward, the telescopic rod 402 is connected to the separation drive mechanism, and the lower end of the telescopic rod 402 is fixedly connected to the worm 202;

[0050] Two connecting shafts 204, both connecting shafts 204 are rotatably disposed outside the connecting pipe 1, and the circumferential surfaces of the two connecting shafts 204 are fixedly connected with turbines 203, and both turbines 203 are meshed with the worm 202; and

[0051] Two clamping claws 206 are fixedly connected to the circumferential surfaces of the two connecting shafts 204 respectively.

[0052] In a specific embodiment of the present invention, when it is necessary to connect the connecting pipe 1 and the two pipes 101, the plug-in rings 103 at the adjacent ends of the two pipes 101 can be plugged into the two connecting rings 102. At this time, the fluids in the two pipes 101 flow, and then the flowing fluid drives the two first water wheels 4 to rotate. When the two first water wheels 4 rotate, the driving shafts 109 fixedly connected thereto are driven to rotate. At this time, the separation driving mechanism provided at the lower end of the driving shaft 109 can transmit the rotational force to the telescopic rod 402, thereby driving the worm 202 fixedly connected to the lower end of the telescopic rod 402 to rotate, and then driving the two turbines 203 to rotate by meshing, and then driving the connecting shafts 204 fixedly connected to the two turbines 203. At this time, the clamping claws 206 on the circumferential surfaces of the two connecting shafts 204 will rotate and clamp the plug-in ring 103, so that the plug-in ring 103 cannot be separated from the connecting ring 102, thereby making the connecting pipe 1 and the two The connection of the pipeline 101 is more stable and tight, thereby improving the detection tightness of the flow detector body 104. Then, when actually testing the valve to be tested, one of the pipelines 101 can be connected to the water source pipeline, and the other pipeline 101 can be connected to the valve to be tested, and the device is set again at the outlet pipe of the test valve to measure the flow rate at the inlet and outlet ends of the test water pump, and then the pressure difference at the inlet and outlet ends of the test water pump is measured by the pressure difference measuring instrument. When the drive shaft 109 and the two first water wheels 4 are actually set, they should be set at the left or right position in the middle of the connecting pipe 1 to ensure that different flow rates are generated on both sides of the two first water wheels 4, so that they will only rotate in a single direction. A data collection module and a calculation module are also provided in the flow detector body 104. The data collection module can detect various data in the fluid, and the calculation module can calculate the collected data according to the formula. The calculation module used by the calculation module is as follows:

[0053] Flow coefficient Calculation formula:

[0054] , where:

[0055] Q - measured water flow in cubic meters per hour (m3 / h);

[0056] ——the net differential pressure of the valve, in kilopascals (kPa);

[0057] ——density of water, in kilograms per cubic meter (kg / m);

[0058] ——Density of water at 15°C, in kilograms per cubic meter (kg / m3).

[0059] Flow resistance coefficient Calculation formula:

[0060] , where:

[0061] --- Net differential pressure of the valve under test, in kilopascals (kPa);

[0062] --- the average velocity of water in the test pipe 101, in meters per second (m / s);

[0063] ———Density of water, in kilograms per cubic meter (kg / m3).

[0064] For details, please refer to Figure 2-Figure 4 The separation drive mechanism consists of a blocking plate 406, a screw 401, a disengagement groove, a screw nut 403 and a second water wheel 407. The screw 401 is fixedly connected to the lower end of the drive shaft 109, the disengagement groove is opened at the upper end of the telescopic rod 402, the screw nut 403 is rotatably connected to the disengagement groove through a bearing, and the screw nut 403 is threadedly connected to the circumferential surface of the screw 401, the second water wheel 407 is fixedly connected to the circumferential surface of the telescopic rod 402, and the blocking plate 406 is fixedly connected to the circumferential inner wall of the connecting pipe 1.

[0065] In this embodiment: when the driving shaft 109 rotates, the screw 401 at its lower end will rotate, and then the screw nut 403 on its circumferential surface will descend, and while descending, the second water wheel 407 on the circumferential surface of the telescopic rod 402 connected to the circumferential surface rotates and gradually descends. When it descends to the left side of the blocking plate 406, the fluid is blocked, so that the telescopic rod 402 will not rotate, thereby keeping the worm 202 from rotating, preventing it from excessively rotating and causing excessive damage to the connection between the clamping claw 206 and the plug-in ring 103.

[0066] For details, please refer to Figure 1 The circumferential surface of the connecting tube 1 is fixedly connected with a connecting arm 302, and the circumferential inner wall of the connecting arm 302 is fixedly connected with a stabilizing rod 304. It also includes multiple transmission mechanisms, each of which is composed of two I-shaped wheels 207, a transmission belt 208 and a transmission shaft 209. The transmission shaft 209 is rotatably connected to the circumferential surface of the connecting tube 1, and the two I-shaped wheels 207 are respectively fixedly connected to the circumferential surface of the connecting shaft 204 and the circumferential surface of the transmission shaft 209. The transmission belt 208 is transmission-connected to the circumferential surfaces of the two I-shaped wheels 207. It also includes multiple connecting mechanisms, each of which is composed of a gear 3, a limiting sleeve 303, a rack 301, a mounting plate 305, an anti-locking plate 306, and a locking plate 307. The disengagement assembly, the connecting block 110 and the connecting hole, the connecting block 110 is fixedly connected to the circumferential surface of one of the plug-in rings 103, the connecting hole is opened at one end of the connecting ring 102 and the connecting block 110, the gear 3 is fixedly connected to the circumferential surface of the transmission shaft 209, the limiting sleeve 303 is slidably connected to the circumferential surface of the stabilizing bar 304, the rack 301 is fixedly connected to the lower end of the limiting sleeve 303, and the rack 301 is meshed with the gear 3, the mounting plate 305 is fixedly connected to the upper end of the rack 301, the connecting rod 306 is fixedly connected to one end of the mounting plate 305, and the connecting rod 306 is slidably connected to the connecting hole, and the anti-disengagement assembly is arranged on one side of the connecting rod 306.

[0067] In this embodiment, before the clamping claw 206 clamps the plug ring 103, the connecting block 110 and the connecting ring 102 can be plugged into the circumferential surface of the two connecting rods 306 through the connecting holes provided in the connecting block 110 and the connecting ring 102. When the connecting shaft 204 rotates, the power is transmitted to the transmission shaft 209 through the transmission belt 208 and the two I-shaped wheels 207, so that it starts to rotate and then drives the gear 3 on the circumferential surface of the transmission shaft 209 to rotate. At this time, the rack 301 and the gear 3 are meshed, so that they start to move closer and move through the mounting plate 305. The connecting rod 306 is driven to move toward the closer end, so that the two pipes 101 are pulled closer to the connecting pipe 1, and the connection tightness between the pipes 101 and the connecting pipe 1 is strengthened. At this time, the connection between the connecting ring 102 and the plug-in ring 103 can be made tighter through the anti-detachment component, thereby strengthening the connection between the connecting pipe 1 and the two pipes 101. When the rack 301 moves, the limiting sleeve 303 can slide on the circumferential surface of the stabilizing rod 304, so that the movement of the rack 301 is more stable, and at the same time, the stabilizing rod 304 can be placed more stably through the connecting arm 302.

[0068] For details, please refer to Fig. 9The anti-slip assembly consists of a placement slot 6, an anti-slip spring 604, an anti-slip block 601, a limiting slot 603 and a limiting block 602. The placement slot 6 is arranged on the circumferential surface of the connecting rod 306, the anti-slip spring 604 is fixedly connected to an inner wall of one side of the placement slot 6, the anti-slip block 601 is fixedly connected to one end of the anti-slip spring 604, the limiting slot 603 is arranged on the circumferential inner wall of the gear 3, the limiting block 602 is fixedly connected to the circumferential surface of the anti-slip block 601, and the limiting block 602 is slidably connected in the limiting slot 603.

[0069] In this embodiment: after the connecting rod 306 is inserted into the connecting hole, the anti-slip spring 604 on the inner wall of one side of the placement slot 6 is elastically expanded, causing the anti-slip block 601 to pop outward, thereby preventing the connecting rod 306 from being separated from the connecting hole. At the same time, when the anti-slip block 601 slides, it can simultaneously drive the limit block 602 to slide in the limit slot 603, thereby preventing the anti-slip block 601 from being separated from the placement slot 6 due to excessive sliding.

[0070] For details, please refer to Figure 1-Figure 7 The circumferential surface of the driving shaft 109 is fixedly connected with the ratchet 2, and the circumferential surface of the driving shaft 109 is rotatably connected with the connecting seat 201, the connecting seat 201 is fixedly connected to the circumferential surface of the connecting tube 1, and the upper end of the connecting seat 201 is rotatably connected with the toggle plate 5 through the rotating shaft 108, one end of the toggle plate 5 is fixedly connected with a pawl 501, and the pawl 501 is intermittently meshed with the ratchet 2, the upper end of the connecting seat 201 is fixedly connected with a force plate 502 and an anti-degree plate 503, and the adjacent ends of the force plate 502 and the toggle plate 5 are fixedly connected with an anti-rebound spring 504.

[0071] In this embodiment: when the driving shaft 109 rotates, the ratchet 2 can be driven to rotate synchronously. At this time, the anti-rebound spring 504 at one end of the force plate 502 elastically expands, pushing and shifting the toggle plate 5 inward, so that the pawl 501 at one end of the toggle plate 5 is intermittently engaged with the ratchet 2 to prevent the driving shaft 109 from rotating in the opposite direction. The anti-rebound spring 504 can prevent the toggle plate 5 from being excessively shifted by the elasticity of the anti-rebound spring 504 through the anti-degree plate 503.

[0073] In this embodiment: when the driving shaft 109 rotates, the driving shaft of the micro-generator 107 will be driven to rotate synchronously, so that it starts to generate electricity and transmits the electricity to the flow detector body 104 through two wires 106, so that the electricity required by it can be sufficiently supported, saving the use of electricity, and the micro-generator 107 can be supported by the stabilizing column 105 to prevent it from falling. It should be noted that the specific model of the flow detector body 104 and the micro-generator 107 to be used is selected by the relevant technical personnel familiar with the field, and the above flow detector body 104 and the micro-generator 107 are all existing technologies, which will not be elaborated in this solution.
