Description

Technical Field

[0001] This utility model is a metal tube float flow meter, belonging to the field of flow meters. Background Technology

[0002] The metal tube float flow meter is a commonly used flow measurement instrument, suitable for measuring the flow rate of liquids and gases. Its working principle is based on the change in position of the float in a vertical tapered tube to indicate the flow rate of the fluid.

[0003] In the existing technology, if a metal tube float flowmeter is installed in a strong electromagnetic field environment (such as near high-power motors, transformers, frequency converters, etc.), the electromagnetic field generated by these devices can easily interfere with the electronic parts of the metal tube float flowmeter. However, common metal tube float flowmeters lack anti-electromagnetic interference structures, which makes them susceptible to electromagnetic interference and affects the accuracy of measurement results. This makes it difficult for metal tube float flowmeters to be used in strong electromagnetic field environments, reducing the applicability of metal tube float flowmeters. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a metal tube float flowmeter to solve the problem mentioned in the background art that the common metal tube float flowmeter is prone to being affected by electromagnetic interference, which makes it easy for the accuracy of its measurement results to be affected by electromagnetic interference due to the lack of an anti-electromagnetic interference structure.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a metal tube float flowmeter, including a float flowmeter body, flanges fixedly connected to both sides of the float flowmeter body, an anti-interference component sleeved on the surface of the float flowmeter body, and a support component provided at the bottom of the anti-interference component;

[0006] The anti-interference component includes a lower housing movably connected to the bottom of the float flowmeter body. A positioning groove is provided at the top of the lower housing, and a positioning block is movably connected in the positioning groove. An upper housing is fixedly connected to the top of the positioning block. Several locking plates are fixedly connected to the sides of both the lower housing and the upper housing. Locking bolts are inserted in the locking plates, and locking nuts are threaded onto the surface of the locking bolts.

[0007] Furthermore, the support assembly includes guide grooves formed on both sides of the lower housing, a drive rod rotatably connected to the inner wall of the lower housing, a knob fixedly connected to one end of the drive rod extending out of the lower housing, two drive gears fixedly connected to the surface of the drive rod, a bidirectional threaded rod rotatably connected to the inner wall of the guide groove, a transmission gear fixedly connected to one end of the bidirectional threaded rod extending out of the guide groove, the transmission gear meshing with the drive gear, and two clamping plates threadedly connected to the surface of the bidirectional threaded rod.

[0008] Furthermore, both the lower housing and the upper housing have clearance openings on both sides, and the diameter of the clearance openings is slightly larger than the diameter of the flange.

[0009] Furthermore, a bracket is fixedly connected to the inner wall of the lower housing, and the top of the bracket is in contact with the surface of the float flowmeter body.

[0010] Furthermore, the length of the lower housing is greater than the length of the float flowmeter body, and the length of the upper housing is equal to the length of the lower housing.

[0011] Furthermore, the clamp is U-shaped, and an anti-slip layer is fixedly connected to the side of the clamp near the main body of the float flowmeter.

[0012] The beneficial effects of this utility model are as follows: By using a drive rod, drive gear, transmission gear, and bidirectional threaded rod, the two clamping plates are driven to slide towards each other along the inner wall of the guide groove until the two clamping plates tightly clamp the pipe, thus fixing the lower housing to the bottom of the pipe. Then, the float flowmeter body is placed into the lower housing and installed between the two pipes through the flange. After the float flowmeter body is installed, the upper housing is fixed to the top of the lower housing by using the positioning block, positioning groove, locking plate, locking bolt, and locking nut, thus completing the installation of the entire metal tube float flowmeter. The lower housing can support the float flowmeter body when disassembling it, thus facilitating the disassembly of the float flowmeter body while preventing it from falling. In addition, the lower housing can also provide additional support for the float flowmeter body during operation, thereby improving the firmness of the connection between the float flowmeter body and the pipe.

[0013] The lower and upper housings effectively prevent external electromagnetic interference during the use of the metal tube float flowmeter, thereby improving the accuracy of the measurement results. Both the lower and upper housings are made of materials resistant to electromagnetic interference. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1 to 3 This utility model provides a technical solution: a metal tube float flow meter, including a float flow meter body 1, flanges 2 fixedly connected to both sides of the float flow meter body 1, an anti-interference component 3 sleeved on the surface of the float flow meter body 1, and a support component 4 provided at the bottom of the anti-interference component 3.

[0021] The anti-interference component 3 includes a lower housing 31 movably connected to the bottom of the float flowmeter body 1. A positioning groove 32 is provided at the top of the lower housing 31. A positioning block 33 is movably connected in the positioning groove 32. An upper housing 34 is fixedly connected to the top of the positioning block 33. Several locking plates 35 are fixedly connected to the sides of both the lower housing 31 and the upper housing 34. Locking bolts 36 are passed through the locking plates 35. Locking nuts 37 are threaded onto the surface of the locking bolts 36.

[0022] The lower housing 31 can be fixed to the bottom of the pipe by the support component 4. The upper housing 34 can be fixed to the top of the lower housing 31 by the positioning block 33, positioning groove 32, locking plate 35, locking bolt 36 and locking nut 37, thus completing the installation of the entire metal tube float flowmeter. The lower housing 31 can support the float flowmeter body 1 when disassembling it, thus facilitating the disassembly of the float flowmeter body 1 while preventing it from falling. During the operation of the float flowmeter body 1, the lower housing 31 can also provide additional support for the float flowmeter body 1, thereby improving the firmness of the connection between the float flowmeter body 1 and the pipe.

[0023] The lower housing 31 and the upper housing 34 effectively prevent external electromagnetic interference during the use of the metal tube float flowmeter, thereby improving the accuracy of the measurement results. Both the lower housing 31 and the upper housing 34 are made of materials resistant to electromagnetic interference.

[0024] Furthermore, both the lower housing 31 and the upper housing 34 have clearance openings 5 ​​on both sides, with the diameter of the clearance openings 5 ​​being slightly larger than the diameter of the flange 2. By setting clearance openings 5 ​​with a diameter slightly larger than that of the flange 2, it is ensured that after the upper housing 34 is fixed to the top of the lower housing 31, the two housings can completely cover the flange 2, thereby avoiding a large gap between the flange 2 and the connection between the lower housing 31 and the upper housing 34. Here, a sealing element such as a rubber ring can be fixedly connected to the inner wall of the clearance opening 5 to achieve a tight wrapping of the flange 2.

[0025] Furthermore, a bracket 6 is fixedly connected to the inner wall of the lower housing 31, and the top of the bracket 6 is in contact with the surface of the float flowmeter body 1. By setting the bracket 6, it is ensured that the center of the float flowmeter body 1 can be on the same horizontal line as the center of the pipeline after it is placed in the lower housing 31, thereby facilitating the docking of the float flowmeter body 1 with the pipeline.

[0026] Furthermore, the length of the lower housing 31 is greater than the length of the float flowmeter body 1, and the length of the upper housing 34 is equal to the length of the lower housing 31. The fact that the length of the lower housing 31 is greater than the length of the float flowmeter body 1 and the length of the upper housing 34 is equal to the length of the lower housing 31 ensures that the lower housing 31 and the upper housing 34 can completely enclose the float flowmeter body 1.

[0027] Please see Figures 1 to 3 As one embodiment of this utility model: the support assembly 4 includes guide grooves 41 opened on both sides of the lower housing 31, a drive rod 42 is rotatably connected to the inner wall of the lower housing 31, a knob is fixedly connected to one end of the drive rod 42 extending out of the lower housing 31, two drive gears 43 are fixedly connected to the surface of the drive rod 42, a bidirectional threaded rod 44 is rotatably connected to the inner wall of the guide groove 41, a transmission gear 45 is fixedly connected to one end of the bidirectional threaded rod 44 extending out of the guide groove 41, the transmission gear 45 meshes with the drive gear 43, and two clamping plates 46 are threadedly connected to the surface of the bidirectional threaded rod 44.

[0028] The drive rod 42, drive gear 43, transmission gear 45 and bidirectional threaded rod 44 drive the two clamping plates 46 to slide towards each other along the inner wall of the guide groove 41 until the two clamping plates 46 tightly clamp the pipe, and the lower housing 31 can be fixed to the bottom of the pipe. Then the float flowmeter body 1 is placed in the lower housing 31 and installed between the two pipes through the flange 2.

[0029] Preferably, the clamping plate 46 is U-shaped, and an anti-slip layer 7 is fixedly connected to the side of the clamping plate 46 near the float flowmeter body 1. By setting the clamping plate 46 into a U-shape, the clamping plate 46 can fit more closely to the pipe surface. With the anti-slip layer 7, the friction between the clamping plate 46 and the pipe can be increased, thereby further improving the fixing effect on the lower housing 31.

[0030] Detailed Implementation: Place the lower housing 31 under two adjacent pipes, ensuring the pipes are positioned between two clamping plates 46. Then, rotate the drive rod 42 by turning the knob, causing it to rotate two drive gears 43 fixed to its surface. This, in turn, drives the bidirectional threaded rod 44 connected to the drive gear 45 to rotate via the transmission gear 43 meshing with the drive gear 43. Consequently, the two clamping plates 46 slide towards each other along the inner wall of the guide groove 41 until they tightly clamp the pipes, thus fixing the lower housing 31 under the two adjacent pipes. Next, place the float flowmeter body 1 into the lower housing 31 and install it between the two adjacent pipes using the flange 2. After the float flowmeter body 1 is installed, place the upper housing 34 on top of the lower housing 31. During this process, the positioning block 33 fixed to the bottom of the upper housing 34 will insert into the positioning groove 32 opened at the top of the lower housing 31, quickly positioning the upper housing 34. Next... The locking bolt 36 is inserted into the locking plate 35 fixed to the surface of the upper housing 34 and the lower housing 31. Then, the locking nut 37 is screwed onto the surface of the locking bolt 36 to complete the installation of the entire metal tube float flowmeter. In order to maintain its measurement accuracy, the float flowmeter body 1 needs to be calibrated and maintained regularly. Therefore, the float flowmeter body 1 needs to be disassembled and reassembled regularly to inspect its internal components. When disassembling the float flowmeter body 1, it is necessary to hold the float flowmeter body 1 with your hand to prevent it from falling, which makes the disassembly and reassembly of the float flowmeter body 1 relatively laborious. The lower housing 31 can support the float flowmeter body 1 when disassembling it, thereby facilitating the disassembly of the float flowmeter body 1 while preventing it from falling. In addition, the lower housing 31 can also provide additional support for the float flowmeter body 1 during operation, thereby improving the firmness of the connection between the float flowmeter body 1 and the pipeline.

[0031] During the use of the metal tube float flowmeter, the lower housing 31 and the upper housing 34 can effectively prevent external electromagnetic interference from affecting the metal tube float flowmeter, thereby improving the accuracy of the measurement results. The lower housing 31 and the upper housing 34 are made of materials that resist electromagnetic interference, such as aluminum and copper.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
