Description

[0001] The present invention relates to the technical field of flowmeters, and in particular to an intelligent control system for a flowmeter. Background Art

[0002] A flow meter is an instrument that indicates the measured flow rate and / or the total amount of fluid in a selected time interval. In simple terms, it is an instrument used to measure the flow rate of fluid in a pipeline or open channel. Flow meters are divided into differential pressure flow meters, rotor flow meters, throttling flow meters, slit flow meters, volumetric flow meters, electromagnetic flow meters, ultrasonic flow meters, etc. Classified by medium: liquid flow meters and gas flow meters.

[0003] After searching, a flow meter is disclosed in the patent publication number CN105547396A, including a measuring tube and an integrating instrument connected thereto through an air chamber seat, and also including a cantilever beam sensor assembled in the air chamber seat, the cantilever beam sensor including an assembly section, a strain section, and a force section for double-sealed assembly connection with the air chamber seat, the force section including a force rod, the lower end of the force rod is connected to a spring sheet, the lower end of the spring sheet is connected to a target rod, and the end of the target rod away from the spring sheet is connected to the target sheet; an overload ring is arranged between the spring sheet and the target sheet on the target rod; the drainage surface of the target sheet is an inner concave arc surface, the downstream surface is cone-shaped, and the outer side surface of the cone is an inner concave arc surface. The present invention has a simple structure, reasonable design, convenient assembly, and stability. Because the spring sheet has a certain rigidity and bendability, when the medium inertia impacts the target sheet or the force-bearing member, the spring sheet will produce corresponding bending deformation, thereby alleviating the impact force directly received by the sensor.

[0004] However, in the above scheme, when the medium inertia impacts the target plate or the force-bearing member, the spring plate will produce corresponding bending deformation, thereby alleviating the direct impact force on the sensor. However, during the use of the flow meter, there is no mechanism that can adjust the water flow entering the guide cavity according to the water pressure at the liquid inlet. The water pressure in the guide cavity is too high or too low, which affects the water output of the liquid outlet, thereby affecting the use of the flow meter. Therefore, an intelligent control system for the flow meter is proposed. Summary of the invention

[0045] Example 3

[0046] Based on Example 2, please refer to Figure 1-8 As shown, the opening adjustment mechanism 4 includes a movable baffle 41, which is rotatably installed in the guide cavity. A first gear 42 is fixedly installed on the top of the movable baffle 41 through a connecting rod. The connecting rod movably passes through the top of the flow meter housing 2.

[0050] Working principle of the present invention: When using the flow meter body 1, first connect the water inlet pipe and the water outlet pipe to the liquid inlet and the liquid outlet of the flow meter housing 2 respectively. When the water flows from the liquid inlet to the liquid outlet, when the water flows through the floating ball 31, the water flow increases and the water pressure at the liquid inlet increases. At the same time, the floating ball 31 will move upward with the rise of the horizontal plane, and at the same time, the movable rod 32 drives the moving inclined block 319 to move upward along the inclined surface of the pushing inclined block 318, and at the same time drives the pushing inclined block 318 to move in the direction close to the fixed plate 39, so that the telescopic The sleeve rod 310 and the first spring 312 are compressed at the same time, and the movable inclined block 311 moves towards the direction close to the fixed plate 39 while pushing the inclined block 318. At the same time, the movable inclined block 311 loses a certain force on the second spring 314 in the compressed state. When the second spring 314 is reset, it drives the moving wheels 321 on both sides of the movable inclined block 311 to move closer to each other on the inclined surface of the movable inclined block 311. When the moving wheels 321 on both sides move closer to each other, the adjusting baffles 38 on both sides are driven closer to each other through the first fixed block 315, thereby adjusting the gap between the two adjusting baffles 38. The water flow at the liquid inlet is reduced, so that the amount of water entering the two diversion cavities is reduced. When the water flow at the liquid inlet is reduced, the water pressure at the liquid inlet is reduced, and at the same time, the floating ball 31 will move downward and upward as the horizontal plane drops. At the same time, the movable inclined block 311 is driven to move away from the fixed plate 39 through the resetting of the telescopic sleeve rod 310 and the first spring 312, and then the adjusting baffles 38 on both sides are driven to move away from each other through the mutual separation of the moving wheels 321 on both sides, thereby increasing the gap between the two adjusting baffles 38, so that the amount of water entering the two diversion cavities is increased. When the floating ball 3 When the movable rod 32 is driven to rise to a certain height, the top of the vertical rod 320 will contact the bottom of the button 35, and the flashing light 34 will be turned on by touching the button 35. The flashing of the flashing light 34 will remind the staff that the water pressure at the liquid inlet is too high. The PLC controller in the control box 6 can start the motor 44 to drive the second gear 43 to rotate, and then drive the first gear 42 to rotate at the same time, and then drive the movable baffle 41 to rotate through the first gear 42, so as to adjust the gap between the movable baffle 41 and the partition 5, and adjust the water outlet size.
