Therefore, they cannot be understood as limitations on the present application. The terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.
[0022] The embodiment of the present application provides an F-type wrench suitable for pipeline valves, such as Figures 1 to 3 As shown. This F-type wrench for pipeline valves includes a first handle 1, a second handle 2, a first clamping opening 3, a second clamping opening 4, a third clamping opening 5, a lug 9, and a locking assembly 6. A slide 11 is provided on the sidewall of the first handle 1. In this embodiment of the present application, the slide 11 is located in the middle of the first handle 1 and extends to near the bottom of the first handle 1. One end of the second handle 2 extends into the first handle 1 and moves along the slide 11. The locking assembly 6 is configured to secure the second handle 2 to the first handle 1. The lug 9 is provided on the side of the first handle 1 away from the second handle 2. The first clamping opening 3, the second clamping opening 4, and the third clamping opening 5 are evenly distributed around the circumference of the first handle 1 and are located on the side of the first handle 1 away from the second handle 2. Multiple trapezoidal teeth 7 are provided on the inner sides of the first clamping opening 3, the second clamping opening 4, and the third clamping opening 5. The trapezoidal teeth 7 enhance the grip of the F-type wrench on the valve, preventing operator injuries caused by poor grip of the F-type wrench.
[0023] The caliber of the first clamping opening 3 is larger than that of the second clamping opening 4, which is larger than that of the third clamping opening 5. Furthermore, the projected length of the first clamping opening 3 along the axial direction perpendicular to the first handle 1 is larger than the projected length of the second clamping opening 4 along the axial direction perpendicular to the first handle 1, and the projected length of the second clamping opening 4 along the axial direction perpendicular to the first handle 1 is larger than the projected length of the third clamping opening 5 along the axial direction perpendicular to the first handle 1. The first clamping opening 3, the second clamping opening 4, and the third clamping opening 5 can be adapted to different valves.
[0024] Specifically, the included angles between the planes where the first clamping opening 3 , the second clamping opening 4 and the third clamping opening 5 are located are all equal, that is, 120°.
[0025] It should be noted that the first clamping port 3, the second clamping port 4 and the third clamping port 5 of the present application can be adapted to multiple models of valves, thereby avoiding the operator from carrying multiple wrenches and reducing the workload of the operator. The lug 9 of the embodiment of the present application can conveniently accommodate an F-type wrench. The cooperation of the first handle 1 and the second handle 2 can adjust the length of the F-type wrench of the pipeline valve. When encountering a larger valve, the second handle 2 is moved in a direction away from the lug 9, thereby increasing the torque and enabling the valve to be opened and closed more effortlessly; when encountering a smaller valve, the second handle 2 is moved in a direction close to the lug 9, thereby facilitating the operator's work. Therefore, the F-type wrench of the pipeline valve of the embodiment of the present application has better adaptability, reduces the amount of wrenches that the operator carries, improves work efficiency, and saves manpower.
[0026] In the prior art, some operators use larger wrenches to fit smaller valves for convenience. Improper use of the wrench can easily damage the valve, affecting the next step of operation. The F-type wrench suitable for pipeline valves in the embodiment of the present application effectively avoids the problem of valve damage caused by selecting an inappropriate wrench.
[0027] In an embodiment of the present application, the locking assembly 6 includes a bolt 61 and a slide 62. The bolt 61 passes through the outer wall of the second handle 2, and its end away from the second handle 2 is located outside the first handle 1. A thread corresponding to the bolt 61 is provided in the second handle 2. The slide 62 is provided on the inner wall of the first handle 1. One end of the bolt 61 is configured to pass through the second handle 2 and lock the slide 62. The second handle 2 of the present application is provided with a thread, which cooperates with the bolt 61 to fix the second handle 2 to the first handle 1.
[0028] In the embodiment of the present application, the locking assembly 6 further includes a handwheel 63. The handwheel 63 is sleeved on the end of the bolt 61 away from the second handle 2. When the handwheel 63 is rotated, the bolt 61 moves toward the slide 62 or away from the slide 62.
[0029] In the embodiment of the present application, the F-type wrench for pipeline valves further comprises an anti-slip layer 8 provided on the end of the second handle 2 away from the first handle 1. The anti-slip layer 8 in the embodiment of the present application is a rubber sleeve, which can increase the friction with the second handle 2.
[0030] In an embodiment of the present application, an F-type wrench suitable for use with a pipeline valve further includes a boss and a connecting shaft. The boss is disposed on the end of the first handle 1 that is distal from the second handle 2. The connecting shaft is fixedly connected to the end of the boss that is distal from the first handle 1. A lug 9 is sleeved on the connecting shaft and rotatably connected to the connecting shaft. When the F-type wrench is to be stored, the lug 9 is unfolded; when the F-type wrench is to be used, the lug 9 is folded so that it is parallel to the top wall of the first handle 1.
[0031] In the embodiment of the present application, the first clamping opening 3 includes two first clamping arms 31 arranged in parallel. The second clamping opening 4 includes two second clamping arms 41 arranged in parallel. The third clamping opening 5 includes two third clamping arms 51 arranged in parallel. The two first clamping arms 31, the two second clamping arms 41, and the two third clamping arms 51 are all vertically connected to the first handle 1. A plurality of trapezoidal teeth 7 are arranged on opposite sides of the two first clamping arms 31, opposite sides of the two second clamping arms 41, and opposite sides of the two third clamping arms 51. The first clamping arm 31, the second clamping arm 41, and the third clamping arm 51 on the side close to the hanging ear 9 are located in the same horizontal plane.
[0032] In the embodiment of the present application, the length of the first arm 31 is 60 mm, the length of the second arm 41 is 40 mm, and the length of the third arm 51 is 25 mm. The first arm 31, the second arm 41, and the third arm 51 are all cylindrical structures, with a diameter of 16 mm for the first arm 31, 12 mm for the second arm 41, and 8 mm for the third arm 51.
[0033] In the embodiment of the present application, the diameter of the first clamping opening 3 is 60 mm, the diameter of the second clamping opening 4 is 35 mm, and the diameter of the third clamping opening 5 is 30 mm.
[0034] Furthermore, the first handle 1 , the second handle 2 , the first clamping arm 31 , the second clamping arm 41 and the third clamping arm 51 of the embodiment of the present application are all made of aluminum bronze, which can play an explosion-proof and anti-static role during the operation process.
