Description

Technical Field

[0001] The invention relates to the technical field of fluid measurement, in particular to a shock-resistant vortex flowmeter. Background Art

[0002] Vortex flowmeter uses the principle of fluid vibration to measure flow and is widely used in various gas measurement in industries such as petroleum, chemical, electric power, metallurgy and coal.

[0003] The patent with publication number CN117346848A discloses a high-stability shock-resistant vortex flowmeter, including a measuring tube and an electromagnetic measuring part, wherein a flow regulating component is provided at the output end of the measuring tube, a shock absorbing component is provided on the tube wall of the measuring tube, and the electromagnetic measuring part is arranged on the shock absorbing component, the shock absorbing component includes a bottom plate, a first shock absorbing part and a second shock absorbing part, the bottom plate is fixed on the tube wall of the measuring tube, the first shock absorbing part is arranged on the bottom plate, the second shock absorbing part is arranged on the first shock absorbing part, and the electromagnetic measuring part is arranged on the second shock absorbing part. When it is detected that the measuring flow in the measuring tube is too small, the flow regulating component is started to reduce the measuring flow flowing out of the output end of the measuring tube, and the measuring flow accumulates in the measuring tube to fill the measuring tube. When the measuring flow impacts the measuring tube due to insufficient measuring flow and causes vibration, the first shock absorbing part first reduces the intensity of the vibration. When the vibration is transmitted to the second shock absorbing part, the shock absorption of the second shock absorbing part reduces the intensity of the vibration again, so that the vibration finally transmitted to the electromagnetic measuring part is greatly reduced, thereby reducing the loss to the electromagnetic measuring part and extending the service life of the electromagnetic measuring part.

[0004] In the above technical solution, when it is detected that the measuring flow in the measuring tube is too small, the flow regulating component is started to gather the regulating blades, and the flow area at the output end of the measuring tube is correspondingly reduced, so that the outflowing measuring flow becomes smaller. The regulating blades are reduced in a gathering form. The flow in the measuring tube will be blocked by the gathered regulating blades when flowing out, which may cause flow backflow. The backflow may cause the fluid to further act on the electromagnetic measuring part, thereby causing measurement errors and damage to the measuring part.

[0079] The working principle of the present invention is as follows:

[0080] The fluid is introduced into the flow tube 101 through the inflow end of the flow tube 101. Through the setting of the flow storage mechanism 6, when the flow rate of the fluid introduced into the flow tube 101 is small, the fluid is blocked by the baffle 602, so that the fluid gradually fills on the side of the flow storage mechanism 6 away from the vortex assembly. When the fluid is filled to above the highest point of the guide cover 603, the fluid can flow to the space where the vortex assembly is located through the space above the guide cover 603 and the inverted U-shaped channel formed between the baffle 602 and the guide cover 603. Through the siphon principle, all the filled fluid can be delivered to the space where the vortex assembly is located through the inverted U-shaped channel.

[0081] By setting the flow storage mechanism 6, when the internal fluid flow of the flow tube 101 is small, it is blocked from entering the measuring space of the vortex component, so that the detection mechanism 2 can be prevented from detecting the flow through the vortex component when the flow is small, thereby eliminating the measurement error when the flow is small and improving the accuracy of the flow meter data summary.

[0082] When the flow rate is small, the fluid flows through the turbine mechanism 5, driving the turbine mechanism 5 to rotate. However, the data error at the rotation measurement point is large. Therefore, by discharging the measurement when the flow rate is small, the rotation of the turbine mechanism 5 at a small flow rate is reduced, thereby reducing the rotation damage of the turbine mechanism 5 and the flow damage of the fluid, thereby increasing the service life of the flow meter.

[0083] By setting the flow storage mechanism 6, the fluid is filled on the side of the flow storage mechanism 6 away from the vortex component, so that after the fluid passes through the vortex component, it can smoothly pass through the outflow end of the flow tube 101 without forming a backflow, thereby reducing the impact and vibration of the fluid backflow on the turbine mechanism 5 and improving the shockproof ability of the flow meter.

[0084] Through the setting of the cover mechanism 4, under normal working conditions, the second shell plate 403 is inserted into the first shell plate 402, the fluid flows normally through the turbine mechanism 5, and the flow meter works normally. The second shell plate 403 is moved out of the first shell plate 402 and fits the adjacent first shell plate 402, so that the cover mechanism 4 forms a semi-closed bowl shape, and at the same time, the slip ring 401 slides relatively along the center rod 301, so that the cover mechanisms 4 with bowl shapes on both sides are docked, so that the turbine mechanism 5 is covered inside the cover mechanism 4. At this time, the measurement of the flow meter can be directly turned off, and when the measurement of the flow meter is turned off, the turbine mechanism 5 can be further protected, thereby improving the use loss of the flow meter.

[0085] By setting the gravity ball 605, by the fit between the gravity ball 605 and the retaining ring 111, and by the abutment between the top column 304 and the guide cover 603, the flow storage mechanism 6 can be fixed in the internal space of the flow tube 101, and by the gravity of the gravity ball 605, when installing the flow tube mechanism 1, there is no need to worry about whether the flow storage mechanism 6 is in the correct position. Instead, after the installation is completed, the flow storage mechanism 6 can automatically make the gravity ball 605 face downward, and the flow storage mechanism 6 can correct itself, thereby simplifying the installation steps of the flow meter.

[0086] The gravity of the gravity ball 605 keeps the gravity ball 605 in the lower position at all times, and the corresponding notch 112 on the retaining ring 111 facilitates the inspection and maintenance of the flow storage mechanism 6. By manually rotating the flow storage mechanism 6 180 degrees, the gravity ball 605 can be aligned with the notch 112 and moved out, so that the ring 601 is close to the inflow end of the flow tube 101, which facilitates the inspection and maintenance of the flow storage mechanism 6 and makes the flow meter easy to inspect.

[0087] The flow meter is installed by docking the flange assembly A and the flange assembly B, and the first flange 104 and the second flange 109 are docked to make the first connection hole 105 and the second connection hole 110 communicate with each other, and the retaining ring 106 is rotated to make it penetrate the first connection hole 105 and the second connection hole 110 and keep its opening facing outward, and then the patch 107 is twisted to make the fixture 108 snap into the opening of the retaining ring 106, and the fixture 108 is further tightened to fix the patch 107, so that the retaining ring 106 is stuck by the fixture 108 and cannot be rotated, thereby forming a tubular connection, simplifying the docking of pipes, and simplifying the installation of the flow meter.

[0088] The detection mechanism 2 is connected to the flow tube 101 through a shock-absorbing assembly, and further forms a three-dimensional support through the first support leg 207 and the second support leg 208. In this way, when the flow tube 101 vibrates, its impact on the detection mechanism 2 can be reduced, and the detection mechanism 2 is further protected by the sheath mechanism 7, thereby improving the shock-absorbing ability of the flow meter and improving the protection performance of the detection mechanism 2.

[0089] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
