[0002] The vortex flow controller is also called a vortex flowmeter or a vortex flow sensor. The vortex flow controller is a fluid flowmeter developed based on the Karman vortex principle. It is mainly used for flow measurement of medium fluids in industrial pipelines. The sensor of the vortex flow controller is usually of a swinging type. During long-term use, foreign particles will adhere to the surface of the sensor. In order to ensure the accuracy of flow calculation, some sensors require long-term cleaning and maintenance. However, the cleaning of existing vortex flow controllers is relatively troublesome. For example, the vortex flow sensor disclosed in Chinese patent CN217384350U needs to be removed together with the pipeline when cleaning, and the valve of the flow tube needs to be closed, which makes cleaning very inconvenient. In view of this, the inventors have made a new invention. Utility Model Content

DETAILED DESCRIPTION

[0019] The following is combined with Figures 1 to 5 The utility model is described in detail.

[0020] The utility model discloses a vortex flow controller with an easy-to-remove sensor, comprising a connecting pipe 1 and an instrument device 2, wherein the two ends of the connecting pipe 1 are respectively provided with a water inlet 11 and a water outlet 12, a choke rod 111 is provided near the water inlet 11 in the connecting pipe 1, the connecting pipe 1 is provided with a through pipe 13 extending laterally, and a threaded portion 131 is provided on the outside of the through pipe 13, the instrument device 2 is provided with a connecting rod 21 that can be inserted into the through pipe 13, and a sensor 22 is provided at one end of the connecting rod 21 that extends into the interior of the connecting pipe 1, the sensor 22 is a swinging sensor 22, and is used to monitor the vortex generated after the fluid collides with the choke rod 111, and the connecting rod 21 A control device 23 is provided at the other end, and the control device 23 is used to calculate the swing data of the sensor 22 as the flow value of the fluid. The connecting rod 21 is also provided with a limiting convex ring 24 that can abut against the end of the through pipe 13. The limiting convex ring 24 can limit the position of the connecting rod 21 extending into the through pipe 13. The outside of the connecting rod 21 is provided with a threaded sleeve 25 that can be threadedly connected to the threaded portion 131. The limiting convex ring 24 is pressed against the end of the through pipe 13 by the threaded sleeve 25, and the instrument device 2 can be fixed on the connecting pipe 1. The flow controller does not need to disassemble the connecting pipe 1. The sensor 22 can be removed from the connecting pipe 1 by simply twisting the threaded sleeve 25. The connecting pipe 1 is provided with two notches 14, each with a raised fixed housing 3 on the outside. A sliding cavity 31 is provided within the fixed housing 3, and a movable gate 32 is disposed within the sliding cavity 31. One end of the gate 32 can be inserted into the notch 14 to seal the connecting pipe 1. A return spring 33 is provided at the other end of the gate 32, which is connected to the bottom of the sliding cavity 31. A lock ring 4 is provided on the fixed housing 3 to secure the gate 32. Specifically, the through pipe 13 is located between the two notches 14. Before removing the meter device 2, the gate 32 near the water inlet 11 is first pressed down. The return spring 33 accumulates elastic force, and the lock ring 4 secures the gate 32 in place, sealing the connecting pipe 1. The gate 32 near the water outlet 12 is then pressed down. The lock ring 4 secures the gate 32 in place, preventing fluid backflow. Finally, the threaded sleeve 25 is loosened to remove the meter device 2. Removing the meter device 2 does not require closing the flow pipe valve, making cleaning and maintenance of the sensor 22 quick and convenient. After the instrument device 2 is reassembled on the connecting pipe 1, the threaded sleeve 25 is tightened to fix the instrument device 2, and then the locking rings 4 on the two fixed shells 3 are opened in turn. The reset spring 33 rebounds and pulls up and resets the gate 32. The operation is simple and easy to use.

[0021] The fixed housing 3 is provided with guide windows 34 on both sides, and an extension rod 35 is provided at one end of the gate 32, which can move in the guide window 34 and extend to the outside of the fixed housing 3. When closing the connecting pipe 1, the user can directly use the fingers of both hands to control the extension rods 35 on both sides of the gate 32, press the gate 32 into the connecting pipe 1, and then press the lock ring 4 with the thumb to fix the gate 32.

[0022] More specifically, the fixed housing 3 is provided with a first positioning hole 36 and a second positioning hole 37 arranged in a vertical sequence. The lock ring 4 is provided with a locking block 41 that is movably connected to the first positioning hole 36, a positioning block 42 that is movably connected to the second positioning hole 37, and a connecting block 43 that connects one end of the locking block 41 and the positioning block 42. The length of the locking block 41 is shorter than that of the positioning block 42. This structure forms the lock ring 4 in a C-shape with a shorter top and a longer bottom. After the extension rod 35 is moved to a specified position, the lock ring 4 is pressed, causing the locking block 41 to extend into the limit window, restricting the movable position of the extension rod 35 and thereby fixing the gate 32.

[0023] A limit plate 44 is provided at the other end of the positioning block 42. The limit plate 44 is larger than the second positioning hole 37. It prevents the locking ring 4 from being separated from the fixed housing 3 and facilitates unlocking the locking ring 4. By pressing the limit plate 44, the user can easily push the locking ring 4, causing the locking block 41 to exit the limit window.

[0024] Likewise, the connecting block 43 is provided with a protrusion 45. The protrusion 45 can be conveniently pressed by the user's thumb to easily push the locking ring 4 so that the locking block 41 extends into the limiting window.

[0025] The connecting pipe 1 is provided with a drain pipe 15. After the two gates 32 seal the connecting pipe 1, the drain pipe 15 can be opened to discharge the fluid inside the connecting pipe 1.

[0026] Flanges 16 are provided at both the water inlet 11 and the water outlet 12. The flanges 16 securely connect the connecting pipe 1 to the flow tube. In the present invention, the connecting rod 21 and the control device 23 are both sealed housings with high waterproof properties. Depending on the application scenario, the vortex flow controller can be installed in an upward forward orientation or downward inverted orientation, providing a wide range of applications.

[0027] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
