Description

Technical Field

[0001] This invention relates to the field of float measuring instrument technology, specifically a high-precision intelligent metal magnetic float flow meter. Background Technology

[0002] A float flow meter is a variable area flow meter, also known as a rotor flow meter, which is a vertical tube with a conical inner hole that expands from bottom to top. The weight of the float is supported by the force generated by the fluid flowing from bottom to top, and the flow rate is indicated by the position of the float in the tube. Metal tube float flow meters are characterized by their robust and reliable structure, wide operating temperature range, high accuracy, low price, and ability to measure flow in various applications. They are available in three installation forms: bottom inlet and top outlet, left inlet and right outlet, and bottom inlet and side outlet.

[0003] Patent application number 202222718701.1 discloses a float-type flow meter with a quick installation structure, including a meter body. The upper and lower sides of the meter body are fixedly connected to fixing plates by bolts. The two fixing plates have two mounting screw holes inside, and the two mounting screw holes are respectively threaded with a first screw and a second screw.

[0004] However, this patent also has the following shortcomings: in cold environments, the fluid in the float-type flow meter will solidify due to the low external temperature, which will cause the flow meter to malfunction. In response to this situation, a high-precision intelligent metal magnetic float flow meter is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision intelligent metal magnetic levitation flow meter to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a high-precision intelligent metal magnetic levitation flow meter, comprising...

[0007] According to the above technical solution, the test chamber has an absorption tube fixedly connected to its bottom and an instrument panel fixedly connected to its surface. The instrument panel has a sliding groove on its surface and also includes;

[0008] The heating element includes a mounting plate fixedly connected to the surface of a test chamber. The surface of the mounting plate is provided with movable parts. A compression bladder is fixedly connected to the inner wall surface of the mounting plate. A compression tube is fixedly connected to the end of the compression bladder away from the mounting plate. The compression tube penetrates the surface of the test chamber. Vibration force is absorbed after entering the compression bladder, thereby protecting the normal operation of the heater.

[0009] The measuring component includes a conical tube fixedly connected to the bottom of the inner wall of the test chamber. The bottom of the conical tube is connected to the top of the absorption tube. A magnetic groove is formed on the surface of the conical tube.

A sliding tooth plate is fixedly connected to the surface of the base plate. Multiple sliding tooth plates are used to divide the fluid with a large volume and high concentration.

[0010] According to the above technical solution, the movable component includes a movable plate, which is fixedly connected to the surface of the mounting plate. A sliding ring is rotatably connected to the surface of the movable plate, and a support plate is fixedly connected to the bottom of the sliding ring.

A heating block is fixedly connected to the top of the heater. The heating block is in contact with the surface of the conical tube. The heat generated after the internal temperature of the heating plate rises enters the conical tube and heats the fluid inside it.

[0012] According to the above technical solution, the measuring component further includes a limiting rod. The limiting rod is fixedly connected to the top of the base plate. The end of the limiting rod away from the base plate is fixedly connected to the top of the inner wall of the test chamber. A float is slidably connected to the surface of the limiting rod.

The floating block is in contact with the surface of the magnetic contact plate. A pointer is fixedly connected to the end of the finger plate away from the guide rod. After being affected by the magnetic field, the floating block will slide in the slide groove through the moving plate to move the pointer upward.

[0013] According to the above technical solution, the movable component further includes a fixing block, which is fixedly connected to the bottom of the support plate. The bottom of the fixing block is provided with a fixing component. The surface of the support plate is provided with a support groove. A pneumatic rod is fixedly connected to both sides of the inner wall of the support groove. A buffer spring is fixedly connected to both sides of the inner wall of the support groove. The buffer spring is in contact with the surface of the pneumatic rod. When the test box vibrates, the vibration force is buffered by the expansion and contraction of the buffer spring on the surface of the pneumatic rod.

[0014] According to the above technical solution, the fixing component includes a fixing ring, an air pressure bladder is fixedly connected to the bottom of the inner wall of the fixing ring, an air outlet pipe is fixedly connected to the surface of the air pressure bladder, the air outlet pipe penetrates the surface of the fixing ring, a clamping plate is fixedly connected to the end of the air outlet pipe away from the air pressure bladder, and a clamping groove is opened at the bottom of the clamping plate. The slider is blown outward by the flow of gas in the connecting hole.

[0015] According to the above technical solution, the fixing component also includes an air pipe, which is fixedly connected to both sides of the inner wall of the clamping groove. One end of the air pipe is connected to an air outlet pipe. A connecting hole is provided at the bottom of the air pipe. A slider is slidably connected to the inner wall of the connecting hole. A gripping block is fixedly connected to the bottom of the slider. A corner hole is provided on the surface of the gripping block. A gripping rod is rotatably connected to the inner wall of the corner hole through a rotating shaft. Finally, the rotation angle of the gripping rod in the corner hole is adjusted to fix it to the ground.

[0016] According to the above technical solution, the number of movable plates is set to two. The two movable plates are symmetrically installed on the surface of the mounting plate with the center line of the test box as the axis of symmetry. The installation position of the test box is adjusted by the two movable plates.

[0017] Compared with the prior art, the present invention provides a high-precision intelligent metal magnetic levitation flow meter, which has the following beneficial effects:

[0018] 1. By setting up a heating component, when the external temperature is too low and the flow meter may not work properly, the heater inside the test chamber can be started first. After the heater is started, it drives the heating plate to heat up. The heat generated after the internal temperature of the heating plate rises enters the conical tube to heat the fluid inside, preventing it from solidifying and causing the flow meter to become unusable.

[0019] 2. By setting up movable parts, the vibration generated after the test chamber is started will interfere with the fluid flowing inside the conical tube, thereby affecting the accuracy of the flow meter measurement. First, the installation angle of the test chamber is adjusted by sliding the sliding ring on the surface of the movable plate. When the test chamber vibrates, the vibration force is buffered by the extension and retraction of the buffer spring on the surface of the pneumatic rod.

[0020] 3. This invention uses a fixing component to bring the fixing block into contact with the ground. The ground compresses the airbag to release gas outward. The gas then enters the air pipe from the outlet pipe and flows through the connecting hole, blowing the slider outward. As the slider moves outward, it moves the grab block. Finally, the rotation angle of the grab rod in the corner hole is adjusted to fix it to the ground. The grab rod fixes the test box. By setting this component, the measuring instrument can be fixed and prevented from shaking in windy weather.

[0021] 4. This invention, by setting up a measuring component, allows the fluid to be divided into larger volumes and higher concentrations by multiple sliding tooth plates after entering the conical tube from the absorption tube. This prevents the fluid from excessively condensing together during subsequent measurements, which would affect the accuracy of the measurement. After being divided, the fluid enters the conical tube and squeezes the float. After being squeezed, the float rises by sliding on the surface of the limiting rod. As a result, the magnetic block on the surface of the float distributes a magnetic field on the surface of the magnetic contact plate. After being affected by the magnetic field, the floating block moves the pointer upward by sliding the moving plate in the groove. When the pointer moves upward to a certain position and stops, the flow rate of the fluid can be confirmed by the position of the pointer on the instrument panel. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1, please refer to Figures 1-2 The present invention provides a technical solution: a high-precision intelligent metal magnetic levitation flow meter, including a test box 1, an absorption tube 2 fixedly connected to the bottom of the test box 1, an instrument panel 3 fixedly connected to the surface of the test box 1, a sliding groove 4 opened on the surface of the instrument panel 3, and also includes;

[0034] Heating component 5 includes a mounting plate 505 fixedly connected to the surface of test chamber 1. A movable component 6 is provided on the surface of the mounting plate 505. A compression bladder 501 is fixedly connected to the inner wall surface of the mounting plate 505. A compression tube 502 is fixedly connected to the end of the compression bladder 501 away from the mounting plate 505, and the compression tube 502 penetrates the surface of test chamber 1. Heating component 5 also includes a support rod 503, which is fixedly connected to the surface of the compression tube 502. A heater 504 is fixedly connected to the end of the support rod 503 away from the compression tube 502. The heater 504 is fixedly connected to the surface of a conical tube 801. A heating block 506 is fixedly connected to the top of the heater 504, and the heating block 506 is in contact with the surface of the conical tube 801. If the external temperature is too low and the flow meter may not function properly, the heater 504 inside the test chamber 1 can be started first. After the heater 504 is started, it will drive the heating block 506 to heat. The heat generated after the temperature inside the heating block 506 rises will enter the conical tube 801 to heat the fluid inside, preventing it from solidifying and causing the flow meter to malfunction. After the flow meter starts working, it will cause vibration on the surface. Long-term vibration will inevitably affect the heater inside the test chamber 1. When the test chamber 1 vibrates, the vibration force generated by the heater 504 can be transmitted from the support rod 503 to the compression bladder 501. The vibration force is absorbed after entering the compression bladder 501, thus protecting the normal use of the heater 504.

[0035] Example 2: Distinguishing features from Example 1: such as Figures 2-3 The movable component 6 includes a movable plate 601, which is fixedly connected to the surface of the mounting plate 505. Two movable plates 601 are symmetrically mounted on the surface of the mounting plate 505 about the center line of the test chamber 1. A sliding ring 602 is rotatably connected to the surface of the movable plate 601, and a support plate 603 is fixedly connected to the bottom of the sliding ring 602. The movable component 6 also includes a fixing block 607, which is fixedly connected to the bottom of the support plate 603. A fixing component 7 is provided at the bottom of the fixing block 607. The surface of the support plate 603 is open... A support groove 604 is provided, and pneumatic rods 605 are fixedly connected to both sides of the inner wall of the support groove 604. Buffer springs 606 are fixedly connected to both sides of the inner wall of the support groove 604. The buffer springs 606 are in contact with the surfaces of the pneumatic rods 605. The vibration generated after starting the test chamber 1 will interfere with the fluid flowing inside the tapered tube 801, thereby affecting the accuracy of the flow meter measurement. First, the installation angle of the test chamber 1 is adjusted by sliding the sliding ring 602 on the surface of the movable plate 601. When the test chamber 1 vibrates, the vibration force is buffered by the extension and retraction of the buffer springs 606 on the surface of the pneumatic rods 605.

The fixing component 7 also includes an air pipe 707, which is fixedly connected to both sides of the inner wall of the clamping groove 705. One end of the air pipe 707 communicates with the air outlet pipe 703. A connecting hole 708 is formed at the bottom of the air pipe 707. A slider 709 is slidably connected to the inner wall of the connecting hole 708. A gripping block 706 is fixedly connected to the bottom of the slider 709. A surface of the gripping block 706 is... The test chamber 1 has a corner hole 710, and the inner wall of the corner hole 710 is rotatably connected to a gripper 711 via a rotating shaft. When encountering uneven terrain or windy weather, in order to prevent the flow meter from shaking during measurement, after adjusting the installation angle of the test chamber 1, the fixing block 607 is brought into contact with the ground. The ground compresses the air bladder 701 to release gas outward. The gas enters the air pipe 707 from the air outlet 703. The gas flows in the connecting hole 708 and blows the slider 709 outward. When the slider 709 moves outward, it drives the gripper 706 to move. Finally, the rotation angle of the gripper 711 in the corner hole 710 is adjusted to fix it to the ground. The test chamber 1 is fixed by the gripper 711, which can fix the measuring instrument and prevent the measuring instrument from shaking in windy weather.

[0037] Example 4: Distinguishing features from Example 1: such as Figures 6-8The measuring component 8 includes a tapered tube 801 fixedly connected to the bottom of the inner wall of the test chamber 1. The bottom of the tapered tube 801 is connected to the top of the absorption tube 2. A magnetic groove 803 is formed on the surface of the tapered tube 801. A magnetic connecting plate 802 is fixedly connected to the inner wall surface of the magnetic groove 803. A base plate 807 is fixedly connected to the bottom of the inner wall of the tapered tube 801. A sliding tooth plate 808 is fixedly connected to the surface of the base plate 807. The measuring component 8 also includes a limiting rod 804 and a top of the base plate 807. A limiting rod 804 is fixedly connected to the test chamber 1. The end of the limiting rod 804 away from the base plate 807 is fixedly connected to the top of the inner wall of the test chamber 1.

A floating block 813 is fixedly connected to the end of the guide rod 812 away from the finger plate 810. The floating block 813 is in contact with the surface of the magnetic plate 802. A pointer 811 is fixedly connected to the end of the finger plate 810 away from the guide rod 812. When the fluid enters the conical tube 801 from the absorption tube 2, it is first divided by multiple sliding tooth plates 808 to prevent the fluid from excessively condensing together during subsequent measurement and affecting the measurement accuracy. After being divided, the fluid enters the conical tube 801 and squeezes the float 805. After being squeezed, the float 805 will rise by sliding on the surface of the limit rod 804. Thus, the magnetic block 806 on the surface of the float 805 will distribute a magnetic field on the surface of the magnetic plate 802. After being affected by the magnetic field, the floating block 813 will slide in the slide groove 4 through the moving plate 809 to move the pointer 811 upward. When the pointer 811 moves upward to a certain position and stops, the fluid flow rate can be confirmed by the position of the pointer 811 on the instrument panel 3.
