Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve operating tools, and in particular to an F-type wrench. Background Technology
[0002] In order to start, stop, regulate and safely control steam, water or other media during the operation of a boiler system, various types of valves are usually installed, such as gate valves, safety valves, pressure relief valves and water supply valves.
[0003] In existing technologies, boiler valves are mostly opened and closed manually using F-type wrenches. These wrenches are often one-piece designs, making them inconvenient to carry and unable to adjust torque according to actual needs. The degree of valve opening and closing usually relies on the operator's experience. Due to differences in experience levels among operators, it's difficult to maintain a consistent valve opening, often requiring multiple attempts to adjust to the correct position. This results in low operational efficiency and high labor intensity. Furthermore, improper valve opening adjustment can cause system pressure fluctuations, leading to increased energy consumption and water treatment costs, ultimately reducing overall energy efficiency.
[0004] Therefore, there is an urgent need for an F-type wrench to solve the above problems. Utility Model Content

[0031] This embodiment provides an F-type wrench, such as Figures 1-3As shown, the F-type wrench includes a torque rod 100 and a wrench head assembly 200. The torque rod 100 is equipped with a torque adjustment component 110. One end of the torque rod 100 has a connector that extends radially along the torque rod 100. The torque adjustment component 110 is used to adjust the torque value of the torque rod 100. The wrench head assembly 200 includes a sleeve 210 and a wrench head 220. One end of the sleeve 210 is fixedly connected to the wrench head 220, and the other end of the sleeve 210 has an interface adapted to the connector, allowing the connector to be inserted into the interface. The wrench head 220 includes two spaced-apart fingers 223, each extending radially along the torque rod 100. By providing the torque adjustment component 110 on the torque rod 100, precise adjustment can be made according to the torque required for opening and closing different valves, achieving controllable output of valve opening and closing torque. This effectively improves the consistency and control accuracy of valve opening and closing, avoids pressure fluctuations caused by opening deviations, and enhances the safety and energy efficiency of the boiler system. Furthermore, the torque rod 100 and the wrench assembly 200 adopt a detachable connection structure, which is convenient for carrying and storage, and also facilitates quick on-site assembly, significantly improving operational flexibility and work efficiency.
[0032] Optionally, such as Figure 1 and Figure 3 As shown, the wrench head 220 includes a wrench head body 221, on which a connecting part 222 is provided. The connecting part 222 is welded to one end of the sleeve 210, and two wrench fingers 223 are spaced apart on the wrench head body 221. By welding the wrench head body 221 to one end of the sleeve 210, a stable connection between the wrench head 220 and the sleeve 210 is achieved.
[0033] Optionally, the connecting portion 222 is welded to one side of the wrench head body 221, and the two wrenches 223 are welded to the other side of the wrench head body 221. This welded connection has high strength and improves the stability of the connection between the wrench fingers 223 and the wrench head body 221. In other embodiments, the two wrenches 223 are integrally bent into shape with the wrench head body 221, and then the connecting portion 222 is welded to the wrench head body 221, simplifying the connection steps and improving production efficiency.
[0034] Optionally, a reinforcing rib is provided at the connection between the finger 223 and the wrench head body 221, which effectively enhances the load-bearing capacity of the finger 223 and the rigidity of the overall structure, prevents the finger 223 from deforming or breaking under high torque, and improves the durability and reliability of the wrench.
[0035] Optionally, a first chamfer structure is provided at the connection between the finger 223 and the wrench head body 221, which can effectively alleviate stress concentration at the connection, reduce the risk of cracks or damage under torque, and improve the overall strength and durability of the wrench head 220.
[0036] Optionally, the cross-section of the connector is rectangular or hexagonal. The cross-sectional shape of the connector is the same as that of the sleeve 210, which achieves a tight fit between the connector and the sleeve 210, ensuring that the torque can be transmitted efficiently and stably, reducing slippage or deflection, and improving the accuracy of valve operation.
[0037] Optionally, such as Figure 1 and Figure 2 As shown, the torque lever 100 has a handle 120 at the end away from the connector, and the torque adjustment component 110 is located at the end of the handle 120 near the connector, so that the operator can easily adjust the torque when holding the wrench, improving the convenience and comfort of operation.
[0038] Optionally, the handle 120 is provided with an anti-slip structure 121, which is an anti-slip ridge and / or anti-slip dot. The anti-slip structure 121 enhances the safety and comfort of operation, enabling the operator to control the torque more precisely during the application of force, improve the accuracy and consistency of valve opening and closing, reduce labor intensity, and improve overall work efficiency and the practicality of the wrench.
[0039] Optionally, one of the outer wall of the connector and the inner wall of the interface is provided with a groove, and the other of the outer wall of the connector and the inner wall of the interface is provided with an elastic retaining ball. The elastic retaining ball can be confined within the groove, so that the connector can be reliably positioned and limited when inserted into the interface, preventing the connector from loosening or accidentally falling off during operation, and improving the stability and safety of the wrench.
[0040] Optionally, the elastic retaining ball includes a spring and a steel ball. In this embodiment, an assembly groove is provided on the outer wall of the connector, and a spring is provided in the assembly groove. One end of the spring abuts against the bottom wall of the assembly groove, and the other end is connected to the steel ball. The spring can provide elastic force to the steel ball, so that the steel ball is stuck in the groove on the inner wall of the interface.
[0041] Optionally, the inner side of the lever 223 is provided with anti-slip teeth or a frosted structure, which can effectively increase the friction between the lever 223 and the valve, prevent slippage during operation, and improve the stability of clamping and the accuracy of force application.
[0042] Optionally, the torque lever 100, socket 210, and wrench head 220 are all made of metal, which improves the overall strength and durability of the F-type wrench, enabling it to withstand larger torques without easily deforming or being damaged. At the same time, the metal material ensures efficient and stable torque transmission, improves the accuracy and consistency of valve opening and closing operations, and enhances the wrench's reliability and service life.
[0043] It should be noted that the structure of the torque adjustment component 110 and the implementation method of torque adjustment are both existing technologies. In this embodiment, the structure of the torque adjustment component 110 and the implementation method of torque adjustment will not be described in detail.
[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
