Description

Technical Field

[0001] This utility model relates to the field of flow detection, and in particular to a calibration device for a float flowmeter. Background Technology

[0002] Float flowmeters are widely used in industrial production and metering. Their measurement accuracy directly affects the control and measurement precision of the production process. However, existing float flowmeter calibration devices have some shortcomings. For example, when installing existing float flowmeters on calibration pipelines, it is difficult to adapt to different specifications of float flowmeters. If the float flowmeter and the pipeline are not compatible, different specifications of conversion joints are required. This leads to deviations when the conversion joints are installed between the float flowmeter and the pipeline, thereby increasing the installation difficulty and making the calibration process less efficient. Utility Model Content

[0003] This invention provides a float flowmeter calibration device that can solve the problem that existing float flowmeters are difficult to adapt to different specifications when installed on calibration pipelines.

[0004] A float flowmeter calibration device includes two adapters and a testing component, as well as a housing with an opening on one side. A connecting assembly is vertically slidably mounted on the housing. One adapter is detachably connected to the connecting assembly. A flexible hose is installed at the free end of the adapter connected to the connecting assembly. One end of the flexible hose passes through the housing and is located outside. A metal tube is installed inside the housing. One end of the metal tube is located outside, and the other end is connected to the other adapter. The testing component is installed between the two adapters.

[0005] Furthermore, the connecting assembly includes a sliding seat that is vertically slidably installed inside the housing. A first clamping plate in a V-shape is horizontally slidably installed on the sliding seat, and a second clamping plate in a V-shape is horizontally slidably installed on the sliding seat. The first clamping plate and the second clamping plate are symmetrically distributed and the inner V-surface is a clamping surface. The clamping surface is used to clamp the adapter.

[0006] Furthermore, the clamping surface of the first clamping plate is symmetrically provided with sliding grooves, and the two free ends of the second clamping plate pass through the two sliding grooves respectively. The limiting member includes two sliding grooves symmetrically provided on the first clamping plate. The two sliding grooves are parallel to the edges along the length direction of the first clamping plate. A sliding block is unidirectionally slidably installed in the sliding groove. An unlocking member for releasing its unidirectional sliding restriction is installed on the sliding block. A threaded rod is threaded through the sliding block. A wedge block is rotatably installed at one end of the threaded rod. The outer V-face of the second clamping plate opposite to the clamping surface is inclined. The inclined surface of the wedge block is used to contact the outer V-face.

[0007] Furthermore, the unlocking component includes a connecting seat constructed on the sliding block, a wedge plate elastically sliding through the connecting seat, and a ratchet groove for inserting the wedge plate is provided on one side of the first clamping plate.

[0008] Furthermore, a baffle is rotatably mounted on the housing, and a recorder is mounted on the baffle. When the baffle blocks the opening of the housing, the recorder faces the detection component.

[0014] Beneficial effects:

[0015] 1. This utility model enables rapid installation of the float flow meter through a movable connecting component, eliminating the need to directly install the float flow meter with the adapter on the pipeline to be tested.

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] like Figures 1 to 9 As shown in the figure, the float flowmeter calibration device provided in this embodiment includes two conversion connectors 6 and a testing element 5. The testing element 5 is an existing float flowmeter. The two mounting ends of the existing float flowmeter are connected by flanges. Different specifications of float flowmeters have different flange specifications. The conversion connectors 6 are existing quick connectors, which are provided with various specifications. Both ends are flanges, such as diameters of 15, 25, 30, 32, 40, and 50 (referring to the size of the flange). Figure 9(As shown), etc., facilitate connection with float flowmeters of different specifications, improving versatility. All pipe connections in this device are achieved using flanges. It also includes a housing 1 with one open side. A connecting assembly 2 is vertically slidably mounted on the housing 1. One adapter 6 is detachably connected to the connecting assembly 2. A flexible hose 3 is installed at the free end of the adapter 6 connected to the connecting assembly 2. One end of the flexible hose 3 passes through the housing 1 and is located on the outside. A metal pipe 4 is installed inside the housing 1, with one end of the metal pipe 4 on the outside and the other end connected to another adapter 6. A detection element 5 is installed between the two adapters 6. In other words, during use, the device is pre-assembled... The adapter 6 is installed at one end of the housing 1 where the metal pipe 4 and flexible hose 3 are located. The adapter 6, connected to the flexible hose 3, is then installed on the connecting assembly 2. The float flowmeter is then installed between the two adapters 6. During this process, the position of the upper adapter 6 can be controlled by moving the connecting assembly 2 up and down, ensuring the float flowmeter can smoothly enter between the two adapters 6, thus quickly adapting to different models of float flowmeters. After the float flowmeter installation is complete, the metal pipe 4 is installed on the dividing end of the detection pipe. After installation, the free end of the flexible hose 3 is installed on the other dividing end of the detection pipe (e.g., ...). Figure 3 As shown, after the initial docking is completed, the design of the flexible hose 3 allows the flexible hose 3 to be well connected to one end of the test pipe after the metal pipe 4 is docked, without the need to repeatedly move the device, thus avoiding deviations during docking and significantly reducing the installation difficulty with the pipe to be tested. Compared with the existing technology, the movable connecting component 2 enables the rapid installation of the float flow meter, eliminating the need to directly install the float flow meter with the conversion connector 6 on the pipe to be tested, effectively avoiding the problem of deviations after the conversion connector 6 is installed with the pipe to be tested. Moreover, after the float flow meter is installed, the design of the flexible hose 3 ensures a full fit with the pipe to be tested, effectively reducing the installation difficulty and thus improving the verification efficiency.

[0029] like Figure 3 , Figure 4 and Figure 6As shown, the specific structure of the connecting component 2 is disclosed. The connecting component 2 includes a sliding seat 201 vertically slidably installed in the housing 1. A V-shaped first clamping plate 202 is horizontally slidably arranged on the sliding seat 201, such that a V-shaped second clamping plate 204 is horizontally slidably installed on the sliding seat 201. The first clamping plate 202 and the second clamping plate 204 are symmetrically distributed, and the inner V-surface is a clamping surface 203. The clamping surface 203 is used to clamp the adapter 6. A limiting member 7 is installed on the first clamping plate 202 to limit the movement of the second clamping plate 204. Preferably, the sliding seat 201 has a sliding cavity 19 inside, and a sliding plate 20 is constructed at the outer tip of the first clamping plate 202. The sliding plate 20 is inserted into the sliding cavity 19 and plays a guiding role. When it is necessary to install the adapter 6 on the sliding seat 201, the second clamping plate 204 is first pulled, so that a closed loop is formed between the second clamping plate 204 and the first clamping plate 202. The gap is increased to ensure that the adapter 6 can be placed between the first clamping plate 202 and the second clamping plate 204. Then, the second clamping plate 204 is moved so that it presses against the adapter 6. The adapter 6 can then be connected to the float flow meter. After connection, because the first clamping plate 202 can move horizontally, the clamping surface 203 of the first clamping plate 202 can be made to fit against the outer periphery of the adapter 6. Finally, the second clamping plate 204 is moved so that the clamping surface 203 of the second clamping plate 204 fits against the outer periphery of the adapter 6. The position of the second clamping plate 204 is limited by the limiting member 7 to complete the limiting of the adapter 6. This installation method can not only clamp different models of adapter 6, but also ensure that the clamping surfaces 203 of the first clamping plate 202 and the second clamping plate 204 are fully fitted against the corresponding adapter 6 when facing different models of adapter 6.

[0030] like Figures 3 to 8 As shown, in some embodiments, the clamping surface 203 of the first clamping plate 202 is symmetrically provided with sliding grooves 701. The two free ends of the second clamping plate 204 pass through the two sliding grooves 701 respectively. The limiting member 7 includes two sliding grooves 702 symmetrically provided on the first clamping plate 202. The two sliding grooves 702 are parallel to the edges along the length direction of the first clamping plate 202 respectively. A sliding block 703 is unidirectionally slidably installed in the sliding groove 702. An unlocking member 8 for releasing its unidirectional sliding restriction is installed on the sliding block 703. A threaded rod 704 is threaded through the sliding block 703. A wedge block 705 is rotatably installed at one end of the threaded rod 704. The second clamping plate 204 is inclined to the outer V-face opposite to the clamping surface 203. The inclined surface of the wedge block 705 is used to contact the outer V-face. Specifically, as shown in the figure... Figure 4As shown, when the second clamping plate 204 moves toward the first clamping plate 202, the second clamping plate 204 can move normally. However, when the second clamping plate 204 moves away from the first clamping plate 202, its movement is restricted. The unlocking component 8 is needed to release the restriction on the second clamping plate 204 so that it can slide freely horizontally. Specifically, two guide rods are symmetrically installed on the sliding seat 201. Both the first clamping plate 202 and the second clamping plate 204 are slidably fitted onto the two guide rods. When the second clamping plate 204 moves toward the first clamping plate 202 and engages with the conversion connector 6, the sliding block 703 moves the wedge plate 80 located on it. The inclined surface of the first clamping plate 202 is attached to the inclined surface of the second clamping plate 204. Then, it is only necessary to tighten the threaded rod 704. As the threaded rod 704 moves downward in a spiral motion, it forces the wedge block 705 to move. At this time, the inclined surface of the wedge block 705 is attached to the inclined surface of the second clamping plate 204. Since the sliding block 703 is sliding in one direction, tightening the threaded rod 704 will force the second clamping plate 204 to form a resisting force in the direction of the first clamping plate 202. This causes the first clamping plate 202 and the second clamping plate 204 to abut and clamp on the adapter 6, thereby enabling quick installation of the adapter 6 and ensuring the firmness after installation.

[0031] like Figures 3 to 8 As shown, the specific structure of the unlocking component 8 is disclosed. The unlocking component 8 includes a connecting seat 801 constructed on the sliding block 703. A wedge plate 802 is elastically slidably passed through the connecting seat 801. A ratchet groove 803 for inserting the wedge plate 802 is provided on one side of the first clamping plate 202. When it is necessary to disassemble the clamped adapter 6, it is only necessary to pull the wedge plate 802 so that the wedge plate 802 is no longer stuck in the ratchet groove 803, thereby releasing the one-way sliding of the sliding block 703. Because the inclined surface of the wedge plate 802 no longer abuts against the inclined surface of the second clamping plate 204, the installation of the adapter 6 can be quickly released, and the adapter 6 can be quickly disassembled from between the first clamping plate 202 and the second clamping plate 204.

[0032] like Figure 1 As shown, in some embodiments, a baffle 9 is rotatably mounted on the housing 1. Preferably, a latch is installed on the housing 1 to limit the closed baffle 9. A recorder 10 is installed on the baffle 9. The recorder 10 is an existing industrial camera. When the baffle 9 blocks the opening of the housing 1, the recorder 10 faces the detection component 5. That is, after the installation of the float flowmeter and the pipeline to be tested is completed, the baffle 9 is closed, and the industrial camera is aimed at the display of the float flowmeter, so that the content on the display can be viewed and recorded remotely.

[0033] like Figure 2 and Figure 4As shown, to prevent the sliding seat 201 from falling due to gravity when moving vertically, an adjusting screw 11 is vertically and rotatably installed inside the housing 1. The sliding seat 201 is threaded onto the adjusting screw 11. One end of the adjusting screw 11 is located on the outside and is equipped with a knob. When the operator rotates the adjusting screw 11, because the sliding seat 201 and the adjusting screw 11 are threadedly engaged, rotating the adjusting screw 11 will cause the sliding seat 201 to move vertically. And because the threaded engagement has self-locking properties, after the sliding seat 201 has moved, there is no need for the operator to limit the sliding seat 201 by lifting or hoisting it, making it more convenient to use.

[0034] like Figure 1 As shown, in some embodiments, multiple lifting rings 12 are installed on the top of the housing 1. In actual operation, the flexible hose 3 is a 304 stainless steel hose, and the other pipes are also made of 304 stainless steel, so the whole structure has a certain weight, which facilitates the transportation of the housing 1 by the staff. An electrical socket 13 is installed on the top of the housing 1. The electrical socket 13 is mainly used to supply power to the float flow meter. The float flow meter has a transmission line and a power line, and the free ends of both pass through the cable routing hole 14 on one side of the housing 1. The power line can be plugged into the electrical socket 13. In this way, even if the power line of the float flow meter is short, it can still supply power to the float flow meter. Moreover, the power supply is located outside the housing 1, which can avoid the possibility of electric shock and short circuit.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, a support frame 15 for supporting the metal pipe 4 is installed inside the housing 1. The metal pipe 4 has a certain weight. In order to avoid the metal pipe 4 from shaking due to uneven force, the design of the support frame 15 can effectively provide good support for the metal pipe 4 and ensure the stability of the metal pipe 4. A drain hole 16 is provided at the bottom of the housing 1. In actual installation, there may be a certain amount of water inside the conversion joint 6, float flow meter, detection pipe, etc. The design of the drain hole 16 can drain the water inside the housing 1.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments, a guide rail 17 is vertically installed on the side of the box 1 away from the opening. The guide rail 17 is located directly behind the conversion connector 6. A slider 18 is installed on the guide rail 17 and is connected to the sliding seat 201. The design of the position of the guide rail 17 allows the guide rail 17 to occupy more space inside the box 1 when the workers are installing the pipes, which further optimizes the overall layout and makes it easier for the workers to install bolts inside the box 1.

[0037] like Figure 2As shown, when the metal pipe 4 with one end located outside is installed with the pipe to be tested, a gap is left between the free end of the metal pipe 4 and the side of the box body 1 that is close to it, so as to facilitate the screwing in of the bolts and nuts. The metal pipe 4 is a stainless steel rigid pipe, which has good corrosion resistance and increases service life.

[0038] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
