Technical Field

[0001] This utility model belongs to the technical field of valve wrench equipment, specifically relating to an F-type wrench suitable for pipeline valves. Background Technology

[0002] In the coal chemical industry, there are various sizes of manual valves used for manual operation in emergencies. Because these valves are not frequently used, the valve handles are often difficult to turn by hand when needed, requiring the use of an F-type torque wrench. However, existing F-type torque wrenches are ill-suited to the diverse sizes of valves on-site. The varying valve handle sizes necessitate carrying multiple F-type torque wrenches of different sizes, impacting operation time, increasing worker workload, wasting manpower, and failing to efficiently meet the timely valve operation requirements of coal chemical production processes.

[0003] Problems and shortcomings:

[0004] 1. Manual valves on site are difficult to operate by hand, resulting in slow valve operation and inability to perform timely operations;

[0005] 2. Traditional F-type torque wrenches have poor compatibility with valve handles of various sizes on site, resulting in mismatched handle sizes and increasing the workload of workers.

[0006] Therefore, an F-type wrench suitable for pipeline valves is proposed. Utility Model Content

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as Figure 1-3 As shown, an F-type wrench suitable for pipeline valves includes a connecting rod 1. A torque rod is welded to the top of the connecting rod 1. Three sets of torque rods of different specifications are integrated into the top of the connecting rod 1, each adaptable to valve handles of different sizes. The direction of use can be switched by rotating the connecting rod 1, achieving "one wrench, multiple adaptability". The torque rods include a thick rod 4, a thin rod 3, and a medium rod 2. The thick rod 4 and thin rod 3 are arranged opposite each other, and the medium rod 2 is positioned between the thick rod 4 and thin rod 3, perpendicular to them. There are two of each of the three sets of torque rods, distributed vertically along the connecting rod 1. The three sets of torque rods are distributed at 90° angles. Rotating the connecting rod 1 allows for quick switching of the adaptable object without changing tools, significantly improving operational efficiency.

[0026] The bottom outer wall of the connecting rod 1 is equipped with a handle 5 and a hand guard 6. The handle 5 is the grip part located at the bottom, which makes the grip more comfortable and secure during operation. The handle 5 is made of non-slip material or texture to enhance grip stability. The hand guard 6 prevents the hand from slipping when applying force and avoids accidental injury.

[0027] The connecting rod 1 has a threaded hole at its bottom, and an extension rod 7 is attached to the bottom of the connecting rod 1. The extension rod 7 extends the length of the connecting rod 1 via a threaded connection, increasing the torque arm length. Torque multiplication: After adding the extension rod 7, the extended torque arm significantly reduces the physical effort required for operation, making it suitable for large or corroded valves. The threaded connection facilitates disassembly and carrying, flexibly addressing different scenario requirements. As the main structure of the F-type wrench, the connecting rod 1 is the core component for torque transmission. Torque rods of different specifications are welded to the top, and the bottom of the connecting rod 1 connects to the extension rod 7 via a threaded hole.

[0028] The specific design of the aforementioned key components will be discussed in detail below:

[0029] The connecting rod 1 is a DN30 steel pipe with a length of 400-600mm. The DN30 steel pipe, with a nominal diameter of approximately 30mm, combines sufficient mechanical strength with lightweight characteristics, making it suitable for high-load operation in industrial environments. The 400-600mm length design provides a basic torque arm length to meet the opening and closing requirements of conventional valves; combined with the extension rod 7, the length can be further extended to accommodate larger valves.

[0030] The outer sides of the thick rod 4, thin rod 3 and middle rod 2 are provided with threads. The thread design can significantly increase the friction between the torque wrench and the operating parts and reduce slippage.

[0031] The thin rod 3 is a Φ10mm, 50mm long threaded bolt rod, with two thin rods 3 welded together at a 50mm gap. The thick rod 4 is a Φ20mm, 50mm long threaded bolt rod, with two thick rods 4 welded together at a 100mm gap. The medium rod 2 is a Φ15mm, 50mm long threaded bolt rod, with two medium rods 2 welded together at an 80mm gap. The thin rod 3 is suitable for small valve handles below DN40. The narrow gap and small diameter design allow for precise clamping of small handles, and the threads increase friction to prevent slippage. The medium rod 2 is suitable for medium-sized valve handles from DN40 to DN80, filling the fit gap between the thin and thick rods 3, and the threaded design ensures stable force application. The thick rod 4 is suitable for large valve handles above DN80, and the wide gap and large diameter provide a larger contact area and torque.

[0032] The extension rod 7 has a threaded post 8 at its top, and the connecting rod 1 has a threaded hole at its bottom, which mates with the threaded post 8 to achieve quick assembly. The standardized threaded interface simplifies the structure and facilitates expansion and maintenance. The threaded connection ensures that there is no risk of loosening during torque transmission.

[0033] The extension rod 7 has a handle 5 and a hand guard 6 on its bottom outer wall. When the extension rod 7 is installed, the bottom handle 5 becomes a new force application point, and the hand guard 6 prevents hand deviation, allowing the operator to apply greater torque stably. For example, for a rusted DN100 valve, the extension rod 7 extends the torque arm from 600mm to over 800mm. Combined with the handle 5 and hand guard 6 design, the operator only needs a small amount of force to open and close the valve. The bottom end of the connecting rod 1 has a threaded hole, through which the bottom of the connecting rod 1 can be further connected to extend the torque arm of the connecting rod 1.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
