Description

Technical Field

[0001] The invention relates to the technical field of steam flow verification, in particular to a steam flow verification and calibration device based on a condensation weighing method. Background Art

[0002] Steam flow calibration is to ensure the accuracy and reliability of the measurement results by calibrating and verifying the steam flow measurement equipment (such as flow meter). Before calibration, it is necessary to select the appropriate method (such as standard meter method, weighing method, volumetric method), prepare standard flow meter, weighing device, timer and other equipment, and check the installation and environmental conditions of the flow meter to be tested. The standard meter method connects the standard flow meter in series with the flow meter to be tested, adjusts the flow rate and records the data, and calculates the error. The weighing method measures the condensate mass through the condenser and weighing device to calculate the steam flow rate. The volumetric method measures the change in steam volume through the volumetric device to calculate the flow rate. After calibration, it is necessary to process and analyze the data, calculate the error and analyze the cause. If necessary, calibrate and adjust the flow meter. Finally, record the calibration data and write a report. Regularly calibrate and maintain the flow meter to ensure its long-term stable operation. Through these steps, steam flow calibration can effectively improve the accuracy of flow measurement;

The water inside the container will cause subsequent weighing results to be biased high, thereby affecting the calculation accuracy of the steam flow.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The internal steam enters the condenser from one end of the condenser through the external steam pipeline through the solenoid valve and the first connecting pipe. The internal motors of the first and second fans drive the fans to rotate to generate airflow, forcing air to pass through the inside of the fins, causing the temperature inside the condenser to begin to drop. The molecular movement speed of the steam or gas inside the condenser slows down, causing its pressure and temperature to drop below the saturation temperature and begin to condense into liquid. The condensed liquid is discharged into the sensor through the second connecting pipe. The sensor senses the passage of condensed water and records it to obtain the steam passage time, and sends the data to the controller.

[0016] 2. The condensed water inside the weighing tank is weighed by the weighing sensor to obtain the mass of the condensed water, and the data is sent to the controller. The solenoid valve tube discharges the condensed water inside the weighing tank into the collection tank for centralized collection after weighing. The upper drive motor in the discharge assembly on the left and right sides drives the upper half gear and the brake wheel disc at the corresponding position to rotate synchronously. The internal gear block of the half gear itself intermittently contacts and meshes with the driven gear at the corresponding position to drive the driven gear to rotate intermittently. The brake wheel disc contacts one end of the upper groove plate at the corresponding position to brake the driven gear in the stopped state. The driven gear intermittently drives the rotating disk to rotate 180 degrees and then stops. The rotating disk drives the rotating disk to rotate 180 degrees and then stops. One end of the moving connecting rod intermittently reciprocates in the circumferential direction, and the connecting rod drives the upper limit slider at the corresponding position to reciprocate left and right in the inner cavity of the slide rod. The teeth of the pawl intermittently engage with the ratchet tooth groove to drive the ratchet to rotate intermittently. The limit block, with the cooperation of the limit spring, intermittently engages with the inner cavity of the ratchet tooth groove while the ratchet rotates, thereby braking the ratchet to achieve intermittent rotation of the gear driven by the ratchet. The rack rod drives the connecting seat to move inward under the action of the rotating force of the gear, and makes the connecting seat in the left and right side discharge assemblies drive the push plate to move inward in the inner cavity of the weighing tank, so as to quickly discharge the condensed water inside the weighing tank into the inside of the solenoid valve tube under pressure, and make the push plate clean the inner wall of the weighing tank.

[0017] To sum up, the present invention optimizes the drainage method, ensures that the condensed water after weighing can be quickly discharged, reduces the retention time of the condensed water inside the container, improves the calculation efficiency, and can completely discharge the internal and external condensed water, ensuring that there is no water inside the container, thereby improving the accuracy of subsequent weighing and calculation.

The steam inside the external steam pipeline enters the condenser tube 35 from one end of the condenser tube 35 through the solenoid valve 34 and the first connecting pipe 32, and contacts the fin 36. The motors inside the first fan 37 and the second fan 38 drive the fans to rotate to generate airflow, and force air to pass through the inside of the fin 36, causing the temperature inside the condenser tube 35 to start to drop. The molecular movement speed of the steam or gas inside the condenser tube 35 slows down, causing its pressure and temperature to drop below the saturation temperature and begin to condense into liquid. The condensed liquid is discharged into the sensor 41 through the second connecting pipe 33. The sensor 41 senses the passage of condensed water and records it to obtain the steam passage time, and sends the data to the inside of the controller 2;

[0032] Step 2: The prefabricated program in the controller 2 controls the pump body 42, the weighing sensor 45, the solenoid valve tube 48, the drive motor 517 and the pressure relief valve 46 to start. The pump body 42 pumps the condensed water in the sensor 41 into the inner cavity of the weighing tank 44 through the pipeline. The weighing sensor 45 weighs the condensed water in the weighing tank 44 to obtain the mass of the condensed water, and sends the data to the controller 2. The prefabricated program in the controller 2 calculates the steam mass flow rate according to the formula steam mass flow rate = mass of condensed water / passing time. The solenoid valve tube 48 is opened to discharge the condensed water in the weighing tank 44 after weighing into the collection tank 47 for centralized collection. The upper drive motor 517 in the discharge assembly 5 on the left and right sides is discharged. The machine 517 drives the upper half gear 518 and the brake wheel disc 519 at the corresponding position to rotate synchronously, and the internal tooth block of the half gear 518 intermittently contacts and meshes with the driven gear 520 at the corresponding position to drive the driven gear 520 to rotate intermittently, and the brake wheel disc 519 contacts one end of the upper groove plate 521 at the corresponding position to brake the driven gear 520 in the stopped state, so that the driven gear 520 intermittently drives the rotating disk 514 to rotate 180 degrees and then stops, and the rotating disk 514 drives one end of the connecting rod 516 to intermittently reciprocate in the circumferential direction, and the connecting rod 516 drives the upper limit slider 511 at the corresponding position to reciprocate left and right in the inner cavity of the slide groove rod 510, so that the limit slider 511 drives the spring sheet at the corresponding position 512 and the ratchet 513 intermittently reciprocate left and right, the spring sheet 512 keeps the ratchet 513 in an inwardly pressed state, so that the teeth of the ratchet 513 intermittently mesh with the tooth grooves of the ratchet 58 to drive the ratchet 58 to rotate intermittently, and the limit block 57, with the cooperation of the limit spring 56, intermittently engages with the inner cavity of the tooth groove of the ratchet 58 while the ratchet 58 rotates, thereby braking the ratchet 58, so that the ratchet 58 drives the gear 59 to rotate intermittently, and the rack rod 53 drives the connecting seat 54 to move inward under the action of the rotational force of the gear 59, and makes the connecting seat 54 in the left and right discharge components 5 drive the push plate 55 to move inward in the inner cavity of the weighing tank 44, so that the condensed water inside the weighing tank 44 can be quickly discharged to the electromagnetic under the action of pressure. The inside of the valve tube 48 is used to clean the inner wall of the weighing tank 44. The pressure relief valve 46 performs pressure relief operation on the inner cavity of the weighing tank 44 while the push plate 55 moves inward to discharge the air inside the weighing tank 44. After the cleaning is completed, the driving motor 517 on the other side drives the half gear 518 and the brake wheel disc 519 to rotate, so that the driven gear 520 below drives the rotating disk 514 to drive the limit slider 511 to reciprocate left and right under the cooperation of the connecting rod 516, and then the limit slider 511 below drives the spring sheet 512 and the pawl 513 at the corresponding position to engage with the ratchet 58, so that the ratchet 58 drives the gear 59 to rotate in the opposite direction, and then the rack rod 53 drives the push plate 55 to move outward under the cooperation of the connecting seat 54.
