Description

Technical Field

[0001] The utility model relates to the technical field of flow meter repair, in particular to a flow meter valve core extractor device. Background Art

[0002] A flowmeter is an instrument that indicates the measured flow rate and / or the total amount of fluid within a selected time interval. Simply put, it is an instrument used to measure the flow rate of fluid in a pipeline or open channel. Existing flowmeters have a very small taper in the valve core and seat holes to accurately measure flow under constant upstream pressure conditions.

[0003] Flowmeters installed in oil pipelines can experience impurities entering their valve cores, causing the rotor to become stuck and the flowmeter to malfunction. This instability leads to inaccurate flow measurements, necessitating repair of the flowmeter valve core. Currently, flowmeter repairs are performed manually, without specialized tools for removing and disassembling the valve core. Manual disassembly has two drawbacks: low efficiency and an increased risk of injury. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a flow meter valve core extractor device, which aims to solve the problem of lack of special tools for removing and disassembling the flow meter valve core during flow meter fault inspection and repair.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A flow meter valve core extractor device, comprising:

[0007] Main pole;

[0008] A secondary rod, screwed to one end of the main rod;

[0009] The expansion sleeve assembly is provided on the end of the auxiliary rod away from the main rod;

[0010] A strong magnetic sleeve is screwed to the other end of the main rod;

[0011] Two strong magnetic columns are sleeved in the strong magnetic sleeve, with the outer sides lower than the bottom surface of the strong magnetic sleeve and fixed.

[0012] Furthermore, the device also includes a sliding sleeve, which is sleeved on the main rod.

[0013] Furthermore, a stopper is provided in the middle of the main rod, and the stopper is located on the side of the sliding sleeve facing the auxiliary rod.

[0014] Furthermore, the expansion sleeve assembly includes:

[0015] The expansion rod is T-shaped and has an internal thread at the end, which is screwed to the auxiliary rod;

[0016] The expansion sleeve is mounted on the expansion rod, and the side close to the large end of the expansion rod is set as a four-petal type;

[0017] The fixing nut is screwed onto the outside of the expansion rod.

[0018] Furthermore, the strong magnet is conical.

[0019] The technical solution adopted by the utility model has the following beneficial effects:

[0020] This device is integrated according to the valve core structure and actual on-site application. The operating distance can be extended by holding the main rod of the long rod. A strong magnetic column is also screwed on the main rod. The flow meter valve core kit can be directly magnetically sucked in by the strong magnetic column and removed. There is no need for workers to touch the flow meter or pipeline with their hands, which improves the safety of the flow meter during maintenance. In addition, this device can be reasonably assembled according to the fault requirements. This device has the advantages of low cost, convenience and practicality, and is particularly suitable as a standard removal tool for flow meters. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In this embodiment, if Figure 3 As shown, a commonly used flow meter valve core device is also listed, which includes a valve core main rod 9, a valve core main sleeve 10 and a valve core pressure plate 11. Based on the valve core device, when the device fails, when its valve core pressure plate 11 falls and fails, hold the main rod 3, align one end of the strong magnetic column 1 to the valve core pressure plate 11, and remove the valve core pressure plate 11 by magnetic force, and then replace it or demagnetize and reinstall it. There is no need for manual disassembly, which avoids the occurrence of burns or contamination caused by direct contact, thereby improving the safety of flow meter maintenance.

[0028] Among them, see Figure 2 The end of the strong magnetic column 1 is conical, which can fit into the conical hole formed after the strong magnetic sleeve 2 is drilled to enhance the connection stability.

[0029] In this example, see Figure 1 and Figure 2 The flowmeter valve core extractor device also includes a sliding sleeve 4, which is sleeved on the main rod 3; and a stopper is also provided in the middle of the main rod 3, and the stopper is located on the side of the sliding sleeve 4 facing the auxiliary rod 5. The stopper and the strong magnetic sleeve 2 form a limit, so that the sliding sleeve 4 can only move within the limit.

[0036] 2. The valve core body falls off the valve core main rod (9): Disassemble it from the threaded connection between the main rod (4) and the auxiliary rod (5), and use the nut end of the main rod (4) and the bolt end of the valve core main rod (9) to guide the buckle, screw together, and slide the movable sleeve (4) to remove the valve core body.

[0037] 3. If the valve core falls off without the valve core rod (9): remove it from the threaded connection between the auxiliary rod (5) and the expansion rod (8), and use the auxiliary rod (5) bolt end and the valve core housing nut end to guide the buckle, screw together, and slide the movable sleeve to remove the valve core body.

[0038] 4. The valve core without the valve core rod (9) falls off and the housing nut end is slipped: After the expansion sleeve (7) is inserted into the valve core housing nut end, tighten the fixed nut (6) to push the expansion sleeve (7) forward and expand it, and remove the valve core body with the movable sliding sleeve (4).
