Description

Technical Field

[0001] The utility model relates to the field of flow meter equipment, in particular to a split flow meter. Background Art

[0002] At present, most of the flow meters adopt a fixed tube shell structure. During the production process, a complex packaging structure is used to install electronic components and sensors inside the shell. The maintenance of the flow meter is more troublesome because it is difficult to disassemble and assemble.

[0003] In addition, conventional flow meters do not have a structural design for heat insulation between the sensor and the electronic components. Therefore, when the flow meter passes through a high-temperature fluid (especially sanitary flow meters that often use high-temperature steam sterilization for sterilization), the internal electronic components are extremely susceptible to the high temperature and heat and may even be damaged. Long-term or high-frequency high heat effects will cause the electronic components to age or even fail, which will lead to inaccurate measurement results of the flow meter.

[0004] Based on this, it is necessary to develop a new split flow meter to solve the above technical problems. Utility Model Content

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] Example: Figure 1As shown, the split flow meter of this embodiment includes a main cavity 1 for liquid to flow through and a shell 2, a cylindrical interface 11 is provided in the middle position of the upper part of the main cavity 1, a detachable seal in the interface 11 is provided with a blocking block 3, the lower end of the blocking block 3 is provided with a flow sensor 4 extending into the interior of the main cavity 1, the lower end of the shell 2 has a tubular sleeve 21, the interface 11 is detachably mounted on the outside of the interface 11, an electronic component 5 is provided in the shell 2, and the flow sensor 4 is connected to the electronic component 5 via a circuit running through the blocking block 3.

[0025] During use, the two ends of the main cavity 1 of the split flow meter of this embodiment are respectively connected to the two pipe interfaces. When the fluid passes through the main cavity 1, the flow sensor 4 can detect the flow, and then feed it back to the electronic component 5, which is displayed in the instrument window. When maintenance is required, the flow meter can be disassembled, the sleeve 21 and the interface 11 can be disassembled, and then the line can be removed, and the blocking block 3 and the flow sensor 4 can be taken out from the interface 11, which is convenient for disassembly and assembly.

[0026] It should be supplemented that: in this embodiment, the electronic component 5 is an electronic component in a conventional flow meter, and its function and model are consistent with those of a conventional flow meter, which will not be described in detail here.

[0027] As a preferred embodiment, the blocking block 3 is a cylindrical component with threads on its outer surface, the inner wall of the interface 11 is provided with internal threads, the blocking block 3 is screwed into the interface 11, and a seal 6 is sandwiched between the upper end of the blocking block 3 and the sleeve 21.

[0028] In the above embodiment, the blocking block 3 is designed as a cylindrical component, with an external thread on its outer surface, and a matching internal thread on the inner wall of the interface 11. The blocking block 3 can be installed in the interface 11 by screwing, and its installation and subsequent removal are very convenient and quick. At the same time, after installation, since a seal 6 is sandwiched between the upper end of the blocking block 3 and the sleeve 21, the sealing performance also meets the requirements of the flow meter.

[0029] In this embodiment, after the blocking block 3 is installed in place, there is a height difference between its upper end and the upper end of the interface 11 , and the sealing member 6 is partially embedded in the groove formed between the upper end of the interface 11 and the blocking block 3 .

[0030] In this embodiment, the sealing member 6 is a conventional rubber pad. A through hole is provided in the middle of the rubber pad, and the line of the flow sensor 4 passes through the through hole in the middle of the rubber pad.

[0031] As a preferred embodiment, Figure 2 As shown, a partition plate 211 is provided in the sleeve 21 , a heat dissipation cavity is provided at the upper end of the partition plate 211 , and a heat dissipation port 212 is provided on the side wall of the heat dissipation cavity.

[0032] In the above-mentioned implementation scheme, an "inner threaded pipe cap structure" threadedly connected to the interface 11 is formed between the partition 211 and the lower end of the sleeve 21, and a heat dissipation cavity is formed above the pipe cap structure. Since the heat dissipation cavity is connected to the outside through the heat dissipation port 212 arranged on the side wall, it is equivalent to setting an air isolation layer between the main cavity of the shell 2 and the interface 11, which can effectively block the heat from being transferred upward through the sealing block 3 into the interior of the shell 2, thereby preventing high heat from damaging the electronic components 5 inside the shell 2.

[0033] It should be additionally explained that: after being installed in place, a sealing member 6 is sandwiched between the lower end of the partition plate 211 and the blocking block 3 .

[0034] As a preferred embodiment, a plurality of heat dissipation openings 212 are provided and are distributed at intervals along the circumference of the heat dissipation cavity.

[0035] In the above embodiment, the heat dissipation openings 212 are evenly arranged along the circumferential direction, so that the heat dissipation effect is better and the appearance is more beautiful.

[0036] In this embodiment, the heat dissipation opening 212 can be dense small holes or slightly larger openings. Of course, when the heat dissipation opening 212 is larger, a dustproof net can be set in the heat dissipation opening 212 to prevent dust from entering and accumulating in the heat dissipation cavity.

[0037] As a preferred embodiment, a cable channel 213 for the circuit to pass through is provided in the middle between the top wall of the heat dissipation cavity and the partition plate 211 .

[0038] In the above embodiment, the design of the cable channel 213 enables the line connecting the flow sensor 4 and the electronic component 5 to be protected to a certain extent when passing through the heat dissipation cavity, thereby avoiding being exposed in the heat dissipation cavity.

[0039] In this embodiment, connection flanges 12 are respectively provided at both ends of the main pipe cavity 1. The design of the connection flanges 12 facilitates the connection between the two ends of the main pipe cavity 1 and the flanges of the ports of other pipe fittings.

[0040] As a preferred embodiment, the upper end of the blocking block 3 is provided with a tool opening for inserting a tool driver for rotation.

[0041] In the above implementation scheme, during the disassembly and assembly of the blocking block 3 (especially during maintenance and disassembly), the tool port on the upper end of the blocking block 3 is particularly important. After removing the sleeve 21, inserting a tool (such as a wrench, etc.) into the tool port can drive the blocking block 3 to rotate upward and disengage from the interface 11, which is relatively convenient to operate.

[0042] As a preferred embodiment, a threaded hole is formed at the lower end of the blocking block 3, and an external threaded connector 41 connected to the threaded hole is provided at the upper end of the flow sensor 4.

[0043] In the above embodiment, the flow sensor 4 is screwed into the threaded hole at the lower end of the blocking block 3 through the external threaded plug post 41 arranged at the upper end thereof, and the disassembly and assembly of the two are relatively convenient.

[0044] In this embodiment, the upper end of the external threaded connector 41 can be set to a smooth surface, and a sealing ring can be embedded on the surface to seal and connect with the upper end of the threaded hole at the lower end of the blocking block 3, thereby improving the sealing performance of the connection between the two.

[0045] As a preferred embodiment, limit blocks 111 are provided on opposite sides of the lower end of the inner wall of the interface 11 , and the lower end of the blocking block 3 abuts against the limit blocks 111 .

[0046] In the above implementation scheme, the design of the limit block 111 allows the blocking block 3 to be tightened downward in the interface 11, and the lower end thereof is restrained from further downward rotation by abutting against the limit block 111. After the two abut against each other, the blocking block 3 is installed in place.
