DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: a vortex flowmeter housing, including a flowmeter housing 2, a connecting cylinder 8, a vortex elimination block 15 and a vortex generator 13. The left and right ends of the flowmeter housing 2 are symmetrically fixed with fixed cylinders 14. Two connecting cylinders 8 are provided. The two connecting cylinders 8 are longitudinally fixed with second sealing rubber rings 71 relative to the outer sides. Connecting rings 9 are fixed to the inner edges of the annular sides of the two connecting cylinders 8 relative to the inner ends. A plurality of springs 10 are installed at equal angles on the inner sides of the two connecting rings 9. Two conical cylinders 11 are respectively installed on the other ends of the plurality of springs 10. The vortex generator 13 is fixed to the right end of the left connecting cylinder 8, and the vortex elimination block 15 is fixed to the left end of the right connecting cylinder 8. The vortex generator 13 is located inside the left fixed cylinder 14, and the vortex elimination block 15 is located inside the left fixed cylinder 14. A flow balancing orifice plate 16 is provided on the left end of the vortex elimination block 15. This design solves the problem that the left and right vortex generating components and the vortex elimination components in the original device are fixed and inconvenient to disassemble.

[0019] As the first embodiment of the utility model: a temperature sensor 3, a pressure sensor 4 and a flow meter 5 are respectively installed at the upper and lower ends of the flow meter housing 2, a display panel 1 is installed at the upper end of the flow meter housing 2, flanges 6 are longitudinally fixed to the left and right edges of the flow meter housing 2, and first sealing rubber rings 7 are arranged on the outside of the two flanges 6. By adding the first sealing rubber ring 7, the left and right ends of the flow meter housing 2 are connected to the external pipeline through the flange 6, and the sealing performance is better.

[0020] The two second sealing rubber rings 71 are respectively located inside the two first sealing rubber rings 7. The two second sealing rubber rings 71 can prevent the outer sides of the two connecting tubes 8 from being exposed to the outside. The two connecting rings 9, the multiple springs 10 and the two conical tubes 11 are all clamped on the annular sides of the two fixed tubes 14. The multiple added springs 10 are in a semi-compressed state, so that after the multiple hexagon socket bolts 12 are removed, the elastic force will be released in the opposite direction, thereby pushing the two connecting tubes 8 in the opposite direction, so that it is convenient for the staff to remove them.

[0021] The vortex generator 13, the left fixed cylinder 14 and the left connecting cylinder 8 are connected and fixed at the connection by multiple hexagon socket bolts 12, and the vortex elimination block 15, the right fixed cylinder 14 and the right connecting cylinder 8 are also connected and fixed at the connection by multiple hexagon socket bolts 12. The added vortex elimination block 15 and the flow equalizing orifice plate 16 have the same through-hole structure, so that the gas in the vortex state in the flow meter housing 2 can be vortex eliminated.

[0022] As a second embodiment of the utility model: when measuring the gas flow, the first sealing rubber ring 7 and the second sealing rubber ring 71 are added, so that when the left and right ends of the flow meter housing 2 are connected to the external pipeline through the flange 6, the sealing is better, and the gas forms a vortex state when passing through the vortex generator 13. The flow meter 5 can monitor the flow of the vortex gas in the flow meter housing 2, and the temperature sensor 3 and the pressure sensor 4 will also detect the temperature and pressure thereof. Then, the gas in the vortex state will be vortex-eliminated through the vortex elimination block 15 and the flow equalizing orifice plate 16;

[0023] When the temperature sensor 3, pressure sensor 4 and flow meter 5 are used for a long time and need to be inspected and repaired, use an external internal angle wrench to unscrew the multiple hexagon socket bolts 12. At this time, the multiple springs 1 in a semi-compressed state will release the elastic force in the opposite direction, and then push the two connecting cylinders 8 in the opposite direction, so that it is convenient for the staff to pull the two connecting cylinders 8 out of the flow meter housing 2. During this process, the two connecting rings 9, multiple springs 10 and two conical cylinders 11 are removed from the annular sides of the two fixed cylinders 14, the vortex generator 13 is removed from the left fixed cylinder 14, and the vortex elimination block 15 and the equalizing orifice plate 16 are removed from the right fixed cylinder 14. At this time, the left and right ends of the flow meter housing 2 will be completely opened, so that it is convenient for the staff to inspect and repair the temperature sensor 3, pressure sensor 4 and flow meter 5 in the flow meter housing 2 for a long time.
