[0002] Currently, steam flow monitoring is generally performed using steam flow meters. However, steam flow meters are usually pre-installed on the steam pipeline and located on the pipeline. For pipelines where no flow meter is installed beforehand, a section of the pipeline needs to be cut off before the steam flow meter can be installed at the cut-off point. This installation is extremely troublesome. Therefore, we have designed a real-time steam flow monitoring device.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-5 This utility model provides a technical solution: a real-time steam flow monitoring device, including a steam chamber 1, and further comprising:

[0036] Steam pipeline 2 is connected to the steam chamber 1 and is used to supply steam to the steam chamber 1;

[0037] A monitoring unit is installed at the connection between the steam pipeline 2 and the steam chamber 1, and is used to monitor the flow rate of steam input into the steam chamber 1 from the steam pipeline 2 in real time.

[0038] The monitoring unit includes:

[0039] A rotating shaft 3 is rotatably disposed inside the steam transmission pipeline 2. One end of the rotating shaft 3 extends into the steam chamber 1 where a fan blade 4 is disposed, and the rotation axis of the rotating shaft 3 is coaxial with the steam transmission pipeline 2.

[0040] Rotating component 5 is disposed on the inner wall of the steam transmission pipeline 2, for bearing the rotating shaft 3 and for rotatably connecting the rotating shaft 3 within the steam transmission pipeline 2;

[0041] Speed ​​measuring element 6 is installed on the wall of the steam chamber 1 to monitor the rotation speed of the fan blade 4. The speed measuring element 6 is a laser speed sensor, which uploads the data monitored by the laser speed sensor to achieve real-time monitoring.

[0042] When steam is delivered from steam pipeline 2 to steam chamber 1, the airflow generated by the steam flowing into steam chamber 1 will drive the fan blade 4 to rotate. The rotation speed of the fan blade 4 is measured by the speed measuring device 6. When the flow rate of steam pipeline 2 is large, the fan blade 4 will rotate faster when it is discharged into steam chamber 1. Thus, the steam flow rate can be monitored in real time based on the rotation speed measured by the speed measuring device 6 to determine whether the steam flow rate is too large, thereby controlling the amount of steam discharged from the front end.

[0043] The rotating component 5 is configured as a rotating ring sleeved on the rotating shaft 3, and the rotating ring is fixed to the inner wall of the steam pipeline 2 by a connecting plate.

[0044] In addition, a pressure relief device 7 is installed on the steam pipeline 2, which is used to temporarily regulate the flow rate in the steam pipeline 2 when the monitoring unit detects that the flow rate in the steam pipeline 2 is too high.

[0045] When the monitoring unit detects that the flow rate in the steam transmission pipeline 2 is too high, resulting in excessive steam and high pressure in the steam chamber 1, and the front-end control needs a certain period of time to react to the pressure relief chamber 71, the excess steam in the steam transmission pipeline 2 during this period is diverted. After the flow rate returns to normal, the diverted steam is discharged into the steam chamber 1.

[0046] Meanwhile, the pressure relief device 7 includes:

[0047] The pressure relief chamber 71 is connected to the steam pipeline 2 at one end through a first connecting pipe and to the steam chamber 1 at the other end through a second connecting pipe. Ball valves are installed on both the first and second connecting pipes to control the connection between the first and second connecting pipes and the steam pipeline 2 and the steam chamber 1, respectively.

[0048] The triggering component, located on the rotating shaft 3, is used to control the opening and closing of the ball valve, while the auxiliary monitoring unit monitors the steam flow rate.

[0049] In addition, the triggering component includes:

[0050] The disc 72 is rotatably disposed at the end of the rotating shaft 3 away from the fan, and the rotating shaft 3 rotates at a fixed point on the disc 72 when rotating;

[0051] Multiple sets of sliding rods 73 are arranged in a circular array on the disk 72 at one end, and each end is provided with a slider 74;

[0052] Multiple sets of sliding grooves 75 are provided on the steam transmission pipeline 2 for sliding of the slider 74;

[0053] Multiple sets of elastic reset members 76 are disposed in each of the slide grooves 75 to provide elastic force to the slider 74 from the fan blade 4 toward the disk 72 side;

[0054] A trigger button 77 is disposed on the slide groove 75. When the slider 74 slides to the trigger button 77, it abuts against the trigger button 77 to open the ball valve. The ball valve is electrically controlled. The trigger button 77 can be opened when the slider 74 abuts against it. When the steam flow is too large, it drives the fan blade 4 to rotate, which will pull the slider 74 on the rotating shaft 3 to slide towards the trigger button 77 until the trigger button 77 is triggered and opened, thereby opening the ball valve and allowing some steam to flow into the pressure relief chamber 71, thereby alleviating the problem of excessive flow. After front-end regulation, the ball valve disposed on the first connecting pipe is closed, while the ball valve disposed on the second connecting pipe will close after a period of time, thereby discharging some steam in the pressure relief chamber 71 into the steam chamber 1 before closing.

[0055] Finally, the elastic reset member 76 includes:

[0056] A round rod 761 is disposed in the sliding groove 75, and a sliding hole is provided on the slider 74 for the slider 74 to slide on the round rod 761;

[0057] A return spring 762 is sleeved on the round rod 761, with one end abutting against the slider 74 and the other end abutting against the end of the groove 75;

[0058] A distance sensor is installed inside the chute 75 to sense the sliding distance of the slider 74, and the sliding distance of the slider 74 is used to help determine the magnitude of the flow rate.

[0059] Alternatively, the distance sensor can be replaced by a pressure sensor located at the return spring 762. The pressure received by the return spring 762 due to the movement of the slider 74 can be used to help determine the steam flow rate.

[0060] Finally, when connecting the various components within the device to the inner wall of the steam pipe or the inner wall of the steam chamber 1, they can be fixed and installed using common methods such as welding and bolts.
