[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1-4 The present invention provides the following technical solution:

[0024] Specifically, it refers to a flow meter for a skid-mounted device, including a flow meter body 1. External flanges 2 are provided on both the left and right sides of the flow meter body 1. A separable pipe 3 is provided between the external flanges 2 and the flow meter body 1. Two first connecting rods 4 are provided on the surface of the external flanges 2 facing the flow meter body 1, which are parallel to each other vertically. A second connecting rod 5 is provided on the surface of the flow meter body 1 near the first connecting rods 4. A movable ball 6 is provided on the surface of the first connecting rods 4 near the second connecting rods 5. A movable groove 7 is provided on the surface of the second connecting rod 5 near the movable ball 6, which is movably sleeved on the outer surface of the movable ball 6. A buffer spring 8 is provided between the flow meter body 1 and the external flanges 2, which is movably sleeved on the outer surfaces of the first connecting rods 4 and the second connecting rod 5.

[0025] When the skid-mounted device is moved and bumps occur, the pipe connected to the external flange 2 vibrates, the external flange 2 is displaced relative to the flow meter body 1, the movable ball 6 rotates in the movable groove 7, and the buffer spring 8 deforms. This achieves the purpose of buffering the flow meter body 1, avoiding damage to the flow meter body 1 after the skid-mounted device is bumped, and ensuring the effect of the flow meter on the skid-mounted device in the later stage.

[0026] Furthermore, a damper 9 is installed between the lower surface of the flow meter body 1 and the base of the skid-mounted device, thereby providing support for the flow meter body 1 and preventing the movable ball 6 from detaching from the movable groove 7 due to lack of support for the flow meter body 1.

[0027] Specifically, the separable pipe 3 includes a first pipe 31 and a second pipe 32. The first pipe 31 is installed on the surface of the flowmeter body 1 facing the external flange 2, and the second pipe 32 is installed on the surface of the external flange 2 facing the flowmeter body 1. A tightening ring 33 is movably fitted on the outer surface of the first pipe 31. The outer surface of the first pipe 31 is provided with threaded teeth. The inner ring of the tightening ring 33 is threadedly connected to the threaded teeth. The outer surface of the second pipe 32 near the first pipe 31 is also provided with threaded teeth. When the first pipe 31 and the second pipe 32 are close together, the tightening ring 33 is rotated, and the tightening ring 33 can rotate onto the second pipe 32. At this time, the tightening ring 33 can fasten the first pipe 31 and the second pipe 32, preventing the first pipe 31 and the second pipe 32 from becoming loose during the use of the flowmeter.

[0028] In this design, sealing rubber rings are provided on the opposite surfaces of the first pipe 31 and the second pipe 32, which increases the sealing between the first pipe 31 and the second pipe 32. At the same time, when the tightening ring 33 is rotated onto the first pipe 31, the sealing rubber rings can also provide room for movement between the first pipe 31 and the second pipe 32, thus avoiding direct contact between the first pipe 31 and the second pipe 32 and preventing friction or even impact between the second pipe 32 and the first pipe 31.

[0029] A rotating ring 34 is rotatably connected to the surface of the tightening ring 33 near the second pipe 32. When the tightening ring 33 rotates, the rotating ring 34 remains stationary. A wavy rubber soft ring 35 is provided between the surface of the rotating ring 34 facing away from the tightening ring 33 and the outer surface of the second pipe 32. When the tightening ring 33 is tightened onto the first pipe 31, the rotating ring 34 moves synchronously with the tightening ring 33. At this time, the rotating ring 34 can exert a pulling force on the rubber soft ring 35, causing the rubber soft ring 35 to stretch. After the tightening ring 33 moves to the first pipe 31, the rubber soft ring 35 blocks the gap between the first pipe 31 and the second pipe 32, minimizing the possibility of external dust or moisture entering the flow meter body 1 through the gap between the first pipe 31 and the second pipe 32, and minimizing the possibility of corrosion inside the flow meter body 1.

[0030] An annular cavity 36 is formed inside the first pipe 31, and a sealing ring 37 is provided inside the annular cavity 36. An annular sealing groove 38 is formed on the surface of the second pipe 32 facing the first pipe 31. The sealing ring 37 slides through the first pipe 31 on the side near the second pipe 32 and matches the sealing groove 38. When the sealing ring 37 extends into the sealing groove 38, it further increases the sealing performance and connection strength between the first pipe 31 and the second pipe 32, ensuring the strength and effectiveness of the flow meter in separating the pipe 3 during use.

[0031] Multiple push rods 39 are provided inside the annular cavity 36. An inner plate 311 is fitted on the outer surface of the push rod 39 inside the annular cavity 36. A spring 312 is movably fitted on the outer surface of the push rod 39 between the inner plate 311 and the inner wall of the annular cavity 36. A rotating plate 310 is hinged between one end of the push rod 39 inside the annular cavity 36 and the sealing ring 37. When the spring 312 is not compressed, the spring 312 will exert a pushing force on the inner plate 311, so that the inner plate 311 is on the side away from the outer surface of the first pipe 31. At this time, the rotating plate 310 exerts a pushing force on the sealing ring 37, so that the initial position of the sealing ring 37 is one side extending into the sealing groove 38.

[0032] The end of the push rod 39 away from the rotating plate 310 slides through the outer surface of the first pipe 31. The vertical cross-section of the tightening ring 33 facing the push rod 39 is a right trapezoid. A contact rod 313 is provided on the side of the push rod 39 facing the tightening ring 33. The other end of the contact rod 313 contacts the inclined surface of the tightening ring 33. When the tightening ring 33 rotates onto the first pipe 31, the inclined surface of the tightening ring 33 can generate a pushing force on the contact rod 313, pulling the contact rod 313 to move outward from the first pipe 31. At the same time, the spring 312 is compressed and contracts. Meanwhile, the rotating plate 310 generates a pulling force on the sealing ring 37, pulling the sealing ring 37 out of the sealing groove 38. With the above structure, after the tightening ring 33 rotates onto the first pipe 31, the sealing ring 37 can be automatically controlled to move out of the sealing groove 38, thus avoiding the problem of the sealing ring 37 and the sealing groove 38 getting stuck when the first pipe 31 and the second pipe 32 are offset.

[0033] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
