Technical Field
[0001] The utility model relates to the technical field of pipeline flow monitoring devices, in particular to a pipeline flow monitoring device for a clean room. Background Art
[0002] A flow velocity and flow meter is a portable measuring instrument specially designed for flow velocity and flow measurement in industries such as hydrology and water conservancy, river flow velocity measurement, farmland irrigation, municipal drainage, industrial sewage, water resources management, ditches and open channels, water conservancy projects, building drainage, and sewage flow measurement. When measuring the flow of a pipeline, a flow velocity and flow meter is often used to monitor the flow velocity. The flow meter is connected to one end of the pipeline, and the flow velocity inside the pipeline is monitored through the flow meter.
[0003] The inventor found during daily use of the flow velocity and flow meter that when the flow meter is connected to the pipeline, flange connection is often used. Then, when the two flange plates are butted together and fixed with screws, if there is no pre-fixing device, the phenomenon of misalignment between the two flange plates may occur, which may lead to troublesome and non-tight connections at the joint, resulting in inaccurate monitoring and thus affecting the measurement. Content of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a pipeline flow monitoring device for a clean room is proposed.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A pipeline flow monitoring device for a clean room includes a flow meter. A flange plate is fixedly connected to the side of the flow meter. A runner is rotatably connected to the inner wall of the flow meter. A display is fixedly connected to the flow meter. A pre-fixing device is arranged on the side of the flange plate. A detection device is arranged on the side of the flow meter. The pre-fixing device includes an L-shaped plate arranged on the flange plate. A round rod is fixedly connected to the side of the L-shaped plate. The round rod is inserted into a round hole opened on the flange plate. A telescopic plate is slidably connected to the side of the L-shaped plate. A baffle is rotatably connected to the side of the telescopic plate. A round hole is opened on the surface of the baffle. The round rod is adapted to the size and shape of the round hole.
[0006] The effects achieved by the above components are as follows: With the cooperation of the round rod and the baffle, the two flange plates can be spliced together, avoiding misalignment during installation, and thus achieving the function of pre-fixing. When it is necessary to monitor the flow inside the pipeline, the flow meter is fixed between the pipelines through the flange plate, and the flow of the pipeline is monitored by the impact of the liquid inside the pipeline on the rotation of the runner, thus achieving the monitoring function.
[0007] Preferably, a groove is formed in the side surface of the L-shaped plate. A first spring is fixedly connected inside the groove, and a telescopic rod is also fixedly connected inside the groove. The first spring is sleeved on the surface of the telescopic rod, and one end of the first spring and the telescopic rod is fixedly connected to one end of the telescopic plate.
[0008] The effect achieved by the above components is that under the action of the first spring, the telescopic plate can be pulled into the groove, and then the round rod is inserted into the baffle to fix the flange.
[0009] Preferably, a clamping ring is fixedly connected to the surface of the round rod, and a cushion block is fixedly connected to the side surface of the baffle. The cushion block is a rubber plate.
[0010] The effect achieved by the above components is that under the action of the clamping ring, after the round rod is inserted into the baffle, it can be clamped, avoiding the phenomenon that the baffle falls off the surface of the round rod. Under the action of the cushion block, the baffle will not make rigid contact with the flange.
[0011] Preferably, a clamping rod is inserted into the side surface of the baffle, and one end of the clamping rod is inserted into the telescopic plate.
[0012] The effect achieved by the above components is that under the action of the clamping rod, the baffle can be fixed after rotating to a suitable position, thus achieving the effect of fixing the baffle.
[0013] Preferably, a second spring is sleeved on the surface of the clamping rod, and both ends of the second spring are fixedly connected to the side surface of the baffle and the end of the clamping rod away from the baffle respectively.
[0014] The effect achieved by the above components is that under the action of the second spring, the clamping rod is inserted into the telescopic plate in a self-locking state for fixation. When the flanges need to be spliced, the two flanges are spliced together, the round rod is inserted into the round hole, the telescopic plate is pulled outwards, so that the baffle can be stuck on the other side of the flange. After the baffle is rotated to a suitable position, under the action of the second spring, the clamping rod is inserted into the telescopic plate in a self-locking state for fixation. Under the action of the first spring, the telescopic plate retracts, and then the round rod is inserted into the baffle. Under the action of the clamping ring, after the round rod is inserted into the baffle, it can be clamped, avoiding the phenomenon that the baffle falls off the surface of the round rod. Under the action of the cushion block, the baffle will not make rigid contact with the flange, thus achieving the effect of pre-fixing the flange.

[0016] The effects achieved by the above components are as follows: Under the interference fit between the annular groove and the sealing ring, the stop block can be firmly fixed together with the through groove, thereby achieving the sealing effect and avoiding the leakage phenomenon of the flowmeter.
[0017] Preferably, a rectangular plate is fixedly connected to the side surface of the flowmeter, a rectangular block is fixedly connected to the side surface of the stop block, a pin is inserted into the surface of the rectangular block, a third spring is sleeved on the surface of the pin, and both ends of the third spring are fixedly connected to the upper top of the rectangular block and the end of the pin away from the rectangular block respectively.
[0018] The effects achieved by the above components are as follows: Under the action of the pin and the third spring, the stop block can be firmly fixed on the side surface of the flowmeter.
[0019] Preferably, a pull belt is arranged on the side surface of the stop block, and the pull belt is made of a flexible material.
[0020] The effects achieved by the above components are as follows: Under the action of the pull belt, the sealing ring can be extruded, which is convenient for taking out the stop block to monitor whether the flowmeter is damaged. When it is necessary to detect the flowmeter, pull out the pin and pull the pull belt, so that the sealing ring is extruded and deformed, resulting in a gap between the annular groove and the sealing ring, which is convenient for taking out the stop block. Then, the flowmeter can be detected through the through groove. After the detection is completed, insert the stop block into the inside of the through groove again. Under the interference fit between the annular groove and the sealing ring, the stop block can be firmly fixed together with the through groove, thereby achieving the sealing effect and avoiding the leakage phenomenon of the flowmeter. Under the action of the pin and the third spring, the stop block can be firmly fixed on the side surface of the flowmeter, thereby achieving the detection effect.

Under the action of the snap ring, after the round rod is inserted into the baffle, it can be clamped to avoid the baffle falling off the surface of the round rod. Under the action of the cushion block, the baffle will not have rigid contact with the flange plate, thereby achieving the effect of pre-fixing the flange plates and solving the problem that the two flange plates may be misaligned during butt joint, resulting in poor sealing.

[0028] Example 1, as Figures 1-4 shown, a pipeline flow monitoring device for a clean room includes a flow meter 1. A flange 6 is fixedly connected to the side of the flow meter 1. A runner 4 is rotatably connected to the inner wall of the flow meter 1. A display 5 is fixedly connected to the flow meter 1. A pre-fixing device 2 is arranged on the side of the flange 6. A detection device 3 is arranged on the side of the flow meter 1. When it is necessary to monitor the internal flow of the pipeline, the flow meter 1 is fixed between the pipelines through the flange 6, and the internal liquid of the pipeline impacts the runner 4 to rotate to monitor the pipeline flow, thereby achieving the monitoring effect.
[0029] Refer to Figures 2-3, the pre-fixing device 2 includes an L-shaped plate 21 provided on the flange 6. A round rod 23 is fixedly connected to the side surface of the L-shaped plate 21. The round rod 23 is inserted into the circular hole opened in the flange 6. A telescopic plate 22 is slidably connected to the side surface of the L-shaped plate 21. A baffle 25 is rotatably connected to the side surface of the telescopic plate 22. A circular hole is opened on the surface of the baffle 25. The size and shape of the round rod 23 are adapted to those of the circular hole. With the cooperation of the round rod 23 and the baffle 25, the two flanges 6 can be spliced together, avoiding the phenomenon of misalignment during installation, and thus achieving the role of pre-fixing. When it is necessary to monitor the internal flow rate of the pipeline, the flow meter 1 is fixed between the pipelines through the flange 6, and the internal liquid of the pipeline impacts the runner 4 to rotate to monitor the pipeline flow rate, and thus achieving the role of monitoring. A groove is opened on the side surface of the L-shaped plate 21. A first spring 210 is fixedly connected inside the groove. A telescopic rod 29 is fixedly connected inside the groove. The first spring 210 is sleeved on the surface of the telescopic rod 29. One end of the first spring 210 and the telescopic rod 29 is fixedly connected to one end of the telescopic plate 22. Under the action of the first spring 210, the telescopic plate 22 can be pulled into the groove, and thus the round rod 23 is inserted into the inside of the baffle 25 to fix the flange 6. A snap ring 24 is fixedly connected to the surface of the round rod 23. A cushion block 26 is fixedly connected to the side surface of the baffle 25. The cushion block 26 is a rubber plate. Under the action of the snap ring 24, after the round rod 23 is inserted into the baffle 25, it can be clamped, avoiding the phenomenon that the baffle 25 falls off from the surface of the round rod 23. Under the action of the cushion block 26, the baffle 25 will not have rigid contact with the flange 6. A clamping rod 27 is inserted into the side surface of the baffle 25. One end of the clamping rod 27 is inserted into the inside of the telescopic plate 22. Under the action of the clamping rod 27, the baffle 25 can be fixed after rotating to a suitable position, and thus achieving the role of fixing the baffle 25. A second spring 28 is sleeved on the surface of the clamping rod 27. Both ends of the second spring 28 are fixedly connected to the side surface of the baffle 25 and one end of the clamping rod 27 away from the baffle 25. Under the action of the second spring 28, the clamping rod 27 is inserted into the inside of the telescopic plate 22 in a self-locking state for fixing. When it is necessary to splice the flanges 6, the two flanges 6 are spliced together, the round rod 23 is inserted into the circular hole, the telescopic plate 22 is pulled outwards, so that the baffle 25 can be clamped on the other side of the flange 6. After the baffle 25 is rotated to a suitable position, under the action of the second spring 28, the clamping rod 27 is inserted into the inside of the telescopic plate 22 in a self-locking state for fixing. Under the action of the first spring 210, the telescopic plate 22 retracts, and thus the round rod 23 is inserted into the inside of the baffle 25. Under the action of the snap ring 24, after the round rod 23 is inserted into the baffle 25, it can be clamped, avoiding the phenomenon that the baffle 25 falls off from the surface of the round rod 23. Under the action of the cushion block 26, the baffle 25 will not have rigid contact with the flange 6, and thus achieving the role of pre-fixing the flange 6.
[0030] Reference Figure 4 As shown in Figure 4 , the detection device 3 includes a through groove 31 formed in the flowmeter 1. A stopper 32 is inserted into the interior of the through groove 31. A sealing ring 33 is fixedly connected to the interior of the through groove 31. A ring groove 34 is formed on the side surface of the stopper 32. Due to the interference fit between the ring groove 34 and the sealing ring 33, the stopper 32 can be firmly fixed to the through groove 31, thereby achieving a sealing effect and avoiding the leakage of the flowmeter 1. A rectangular plate is fixedly connected to the side surface of the flowmeter 1. A rectangular block 36 is fixedly connected to the side surface of the stopper 32. A pin 37 is inserted into the surface of the rectangular block 36. A third spring 38 is sleeved on the surface of the pin 37. Both ends of the third spring 38 are fixedly connected to the upper top of the rectangular block 36 and the end of the pin 37 away from the rectangular block 36 respectively. Under the action of the pin 37 and the third spring 38, the stopper 32 can be firmly fixed to the side surface of the flowmeter 1. A pull belt 35 is arranged on the side surface of the stopper 32. The pull belt 35 is made of a flexible material. Under the action of the pull belt 35, the sealing ring 33 can be squeezed, thereby facilitating the removal of the stopper 32 to monitor whether the flowmeter 1 is damaged. When it is necessary to detect the flowmeter 1, the pin 37 is pulled out and the pull belt 35 is pulled, so that the sealing ring 33 is squeezed and deformed, thereby creating a gap between the ring groove 34 and the sealing ring 33, and facilitating the removal of the stopper 32. Thus, the flowmeter 1 can be detected through the through groove 31. After the detection is completed, the stopper 32 is inserted into the interior of the through groove 31 again. Due to the interference fit between the ring groove 34 and the sealing ring 33, the stopper 32 can be firmly fixed to the through groove 31, thereby achieving a sealing effect and avoiding the leakage of the flowmeter 1. Under the action of the pin 37 and the third spring 38, the stopper 32 can be firmly fixed to the side surface of the flowmeter 1, thereby achieving the detection effect.
[0031] Working principle: When the pipeline flow monitoring device is needed and the internal flow of the pipeline needs to be monitored, the flowmeter 1 is fixed between the pipelines through the flange 6. The rotation of the runner 4 is impacted by the liquid inside the pipeline to monitor the pipeline flow, thus achieving the monitoring function. When the flange 6 needs to be spliced, the two flanges 6 are spliced together. The round rod 23 is inserted into the round hole. The telescopic plate 22 is pulled outwards so that the baffle 25 can be stuck on the other side of the flange 6. After the baffle 25 is rotated to the appropriate position, under the action of the second spring 28, the clamping rod 27 is inserted into the telescopic plate 22 in a self-locking state for fixation. Under the action of the first spring 210, the telescopic plate 22 retracts, and then the round rod 23 is inserted into the baffle 25. Under the action of the snap ring 24, after the round rod 23 is inserted into the baffle 25, it can be clamped, avoiding the phenomenon that the baffle 25 falls off the surface of the round rod 23. Under the action of the cushion block 26, the baffle 25 will not make rigid contact with the flange 6, thus achieving the function of pre-fixing the flange 6. When the flowmeter 1 needs to be detected, the pin 37 is pulled out, and the pull belt 35 is pulled, so that the sealing ring 33 is squeezed and deformed, and then a gap is generated between the annular groove 34 and the sealing ring 33, thus facilitating the removal of the block 32. Then the flowmeter 1 is detected through the through groove 31. After the detection is completed, the block 32 is inserted into the through groove 31 again. Under the interference fit between the annular groove 34 and the sealing ring 33, the block 32 can be firmly fixed together with the through groove 31, thus achieving the sealing function and avoiding the phenomenon of leakage of the flowmeter 1. Under the action of the pin 37 and the third spring 38, the block 32 can be firmly fixed on the side of the flowmeter 1, thus achieving the detection function.
