[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of this application.
[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.
[0030] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0031] In the description of the present application, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present application.
[0032] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0033] There are usually many valves on pipelines such as water supply pipelines, some of which are located underground and need to be opened and closed or inspected and maintained through underground valve wells. However, the diameter of some underground valve wells is small, and it is difficult for operators to go down to the wells. Moreover, sometimes due to the installation position of the valve, it is not convenient for operators to open and close the valve even if they go down to the well. At the same time, when operators go down to the underground valve wells to work, due to the small space, they are easily injured during the process of opening and closing the valves.
[0034] In addition, valves on some pipelines, such as valves on some steam pipelines, are installed high above the ground (for example, more than two meters), and will rust after long-term use. In this case, operators often have difficulty operating them due to height and strength issues.
[0035] It can be seen that valves on some pipelines, for example, valves installed in underground valve wells and valves on steam pipelines, are inconvenient to open and close. It is difficult for operators to open and close the corresponding valves by hand, which affects the opening and closing efficiency of the corresponding valves.
[0036] In view of the above problems, the present application provides a valve opening and closing tool.
[0037] Figure 1-Figure 2 The structure of the valve switching tool of the present application is exemplarily shown.
[0038] See also Figure 1 and Figure 2 In the present application, the valve switch tool 10 includes a support rod 1 and an action part 2. The action part 2 includes a first rod 21, a second rod 22 and a third rod 23. The first rod 21 and the second rod 22 are arranged side by side on the support rod 1 along the axial direction of the support rod 1, and the third rod 23 is connected to the end of the second rod 22 and bent relative to the second rod 22, so that a space for the hand wheel 5 of the valve to pass through is formed between the first rod 21 and the second rod 22 and between the second rod 22 and the third rod 23, so that the action part 2 can contact the hand wheel 5 at three positions, so that when the support rod 1 is rotated, the hand wheel 5 can be driven to rotate through the action part 2 to open or close the valve.
[0039] Based on the valve opening and closing tool 10, the valves on the pipeline can be opened and closed conveniently.
[0040] When using, the operator only needs to Figure 2 As shown, the second rod 22 of the valve switching tool 10 passes through the gap of the handwheel 5 of the valve, and the second rod 22, the first rod 21 and the third rod 23 are all against the handwheel 5 of the valve and contact the handwheel 5, so that the valve switching tool 10 is installed and fixed on the handwheel 5. Then, the support rod 1 is rotated to turn the handwheel 5 to open or close the valve.
[0041] In the above process, since the operator can open and close the valve by using the valve opening and closing tool 10, there is no need to open and close the valve manually. Therefore, the difficulty of opening and closing the valve can be effectively reduced and the opening and closing efficiency of the valve can be improved.
[0042] Moreover, the action part 2 of the valve switching tool 10 can be clamped on the handwheel 5 of the valve through the first rod 21, the second rod 22 and the third rod 23, and can contact the three different positions of the handwheel 5 through the first rod 21, the second rod 22 and the third rod 23. Therefore, it can be stably and reliably combined with the handwheel 5, effectively preventing slipping during the valve switching process, which is also conducive to reducing the difficulty of valve switching and improving the valve switching efficiency.
[0043] At the same time, the first rod 21, the second rod 22 and the third rod 23 are convenient for adapting to valves of various models, have strong versatility and a wide range of applications.
[0044] In addition, the support rod 1 and the action part 2 of the valve switching tool 10 can cooperate to play the role of a force-increasing rod, so that the operator only needs a small force to open and close the valve. In particular, the operator can easily open and close the valve that is difficult to open and close due to rust and other reasons. From this perspective, it is also beneficial to reduce the difficulty of opening and closing the valve and improve the opening and closing efficiency of the valve.
[0045] At the same time, the support rod 1 of the valve switching tool 10 makes it convenient for the operator to stand on the ground and switch the valve located underground or at a higher position without having to go down into the well or climb to a high place. From this perspective, it is also beneficial to improve operational safety, reduce the difficulty of valve switching, and improve the valve switching efficiency.
[0046] It can be seen that the provided valve switching tool 10 can effectively reduce the difficulty of valve switching, improve the valve switching efficiency, and improve the valve switching safety.
[0047] See also Figure 1 In some embodiments, the third rod 23 is parallel to the second rod 22; and / or, the second rod 22 is parallel to the first rod 21. Figure 2 , the first rod 21, the second rod 22 and the third rod 23 can be in contact with the hand wheel 5 more fully, so that the action part 2 and the hand wheel 5 are combined more smoothly and reliably, thus being more conducive to reducing the risk of slipping and improving the switching efficiency of the valve.
[0048] Also, see Figure 1 In some embodiments, the first rod 21 and the second rod 22 extend toward the same side relative to the support rod 1. Figure 2 , which makes it easier for the first rod 21, the second rod 22 and the third rod 23 to fully contact the hand wheel 5, and is therefore more conducive to improving the efficiency of the switch valve.
[0049] Back to Figure 1 In some embodiments, the valve opening and closing tool 10 includes not only the support rod 1 and the action part 2, but also a handle 3, which is arranged at one end of the support rod 1 away from the action part 2. In this way, during the valve opening and closing process, the operator can hold the handle 3 and rotate the support rod 1, which is more labor-saving and convenient, and therefore is conducive to further improving the opening and closing efficiency of the valve.
[0050] In the case where the valve opening and closing tool 10 includes a handle 3, Figure 1 In some embodiments, the valve opening and closing tool 10 further includes a stopper 4, which is disposed between the handle 3 and the support rod 1 and / or at an end of the handle 3 away from the support rod 1, and protrudes radially outward from the support rod 1 relative to the handle 3. In this way, during the valve opening and closing process, the stopper 4 can limit the operator's hand to prevent the operator's hand from slipping, thereby further improving the valve opening and closing efficiency.
[0051] In addition, in some embodiments, an anti-slip portion (not shown) is provided on the handle 3. In this way, during the valve opening and closing process, the anti-slip portion can prevent the operator from slipping during the process of rotating the handle, thereby further improving the valve opening and closing efficiency.
[0052] In the aforementioned embodiments, the length of the support rod 1 may be fixed or adjustable.
[0053] Among them, when the length of the support rod 1 is adjustable, it is convenient for the valve switching tool 10 to switch valves at different depths and heights, which can not only effectively improve the versatility of the valve switching tool 10, so that the valve switching tool 10 can switch more valves and expand the scope of application of the valve switching tool 10, but also further reduce the probability of operators climbing up and down, and realize flexible adjustment of the force arm of the force rod. Therefore, it is also conducive to further reducing the difficulty of valve switching and improving the valve switching efficiency.
[0054] In order to make the length of the support rod 1 adjustable, in some embodiments, the support rod 1 includes at least two rod segments (not shown) connected to each other, and the at least two rod segments move and / or rotate relative to each other to adjust the length of the support rod 1. Specifically, in some embodiments, the at least two rod segments are threadedly connected, slidably connected, or rotatably connected to make the length of the support rod 1 adjustable. Based on this, the length adjustment of the support rod 1 can be conveniently achieved, thereby improving the versatility of the valve switching tool 10, expanding the scope of application of the valve switching tool 10, reducing the difficulty of valve switching, and improving the valve switching efficiency.
[0055] In addition, the valve switch tool 10 in the above-mentioned embodiments can be made of various materials. For example, the valve switch tool 10 is made of stainless steel. In this way, the valve switch tool 10 has the characteristics of corrosion resistance, high strength and easy cleaning, higher structural reliability, longer service life, wider application range, and is particularly suitable for switching downhole valves and steam pipeline valves.
[0056] Next, combine Figure 1-Figure 2 The embodiments shown are used to further introduce the present application.
[0057] like Figure 1 and Figure 2 As shown, in this embodiment, the valve switching tool 10 is made of stainless steel material and includes a support rod 1, an action portion 2, a handle 3 and a limit platform 4.
[0058] The support rod 1 is used to transmit the rotational torque to the action part 2, so as to drive the hand wheel 5 of the valve to rotate through the action part 2 to open or close the valve. Figure 1 As shown, in this embodiment, the axis of the support rod 1 is a straight line, and the cross section is circular.
[0059] The action part 2, the handle 3 and the limit platform 4 are all arranged on the support rod 1, and the action part 2 and the handle 3 are respectively located at two opposite ends of the support rod 1, namely, the first end and the second end.
[0060] The action part 2 is used to engage with the hand wheel 5 of the valve to realize the installation and fixation of the valve switch tool 10 on the hand wheel 5, and the transmission of the rotation torque from the support rod 1 to the hand wheel 5, so that when the support rod 1 is rotated, the hand wheel 5 can be driven to rotate through the action part 2 to realize the opening and closing of the valve. Figure 1 As shown, in this embodiment, the action part 2 includes a first rod 21, a second rod 22 and a third rod 23. The first rod 21 and the second rod 22 are arranged side by side along the axial direction of the support rod 1, and are arranged in sequence along the direction from the second end to the first end of the support rod 1, so that the second rod 22 is located at the end of the support rod 1, and the first rod 21 is located on the side of the second rod 22 close to the handle 3, and is arranged at intervals from the second rod 22 to form a space for the hand wheel 5 of the valve to pass through. The cross-sections of the first rod 21 and the second rod 22 are both circular, and the two extend from the support rod 1 to the same side and are parallel to each other. The second rod 22 and the support rod 1 have an arc transition to reduce stress concentration and improve structural reliability. The third rod 23 is connected to the end of the second rod 22 away from the support rod 1, and is bent in the opposite direction relative to the second rod 22, so that the third rod 23 and the second rod 22 are parallel to each other, but extend in opposite directions, and a space for the hand wheel 5 of the valve to pass through is formed between the two. The third rod 23 and the second rod 22 have an arc transition to reduce stress concentration and improve structural reliability.
[0061] The handle 3 is used for the operator to apply a rotational torque. Figure 1 As shown, in this embodiment, the handle 3 is cylindrical, which is convenient for the operator to grasp.
[0062] The limiter 4 is used to limit the operator's hands to prevent them from slipping. Figure 1 As shown, in this embodiment, a limit platform 4 is provided between the handle 3 and the support rod 1, and at the end of the handle 3 away from the support rod 1. Thus, the valve switch tool 10 includes two limit platforms 4, which can limit the operator's hand from the front and back directions, thereby more reliably preventing the hand from slipping. Figure 1 It can be seen that the two limit platforms 4 of this embodiment are both cylindrical and both protrude from the handle 3 in the radial direction of the support rod 1, but the radial sizes of the two are inconsistent. The diameter of the limit platform 4 located between the handle 3 and the support rod 1 is larger than the diameter of the limit platform 4 located at the end of the handle 3 away from the support rod 1, forming two limit platforms 4 of different sizes. In this way, not only is the structure beautiful, but also a better anti-slip effect can be achieved based on a simpler structure.
[0063] Based on the valve switching tool 10 of this embodiment, when the operator switches the stop valve or other valves in the valve well, there is no need for the operator to enter the well with his whole body. Instead, he only needs to lift the valve well cover and stand at the wellhead to operate. In this way, it can avoid the problem that the operator has difficulty entering the well due to the small size of the valve well, the small space in the well, or the small space where the valve is located, which makes it difficult for the operator to operate even if he enters the well and is prone to injury.
[0064] At the same time, based on the valve switching tool 10 of this embodiment, when the operator switches the valve in a higher position, there is no need to climb up to a high place, but only needs to stand on the ground to operate. In this way, it can avoid the problem that the valve is too high and the operator cannot operate it due to height problems, or needs to climb up to operate it.
[0065] When in use, it is only necessary to insert the second rod 22 of the valve switching tool 10 into the gap of the handwheel 5, so that the first rod 21, the second rod 22 and the third rod 23 are in contact with the handwheel 5 at three different positions, so as to achieve the engagement of the action part 2 with the handwheel 5, and then rotate the handle 3 to switch the valve. It is not easy to slip, and it saves time and effort, is convenient and quick, and even a rusty valve can be quickly opened and closed.
[0066] It can be seen that the valve switching tool 10 of this embodiment can perform switching operations on various valves with handwheels 5, whether they are above ground or underground, rusty or not. It not only has a wide range of applications, but also does not require operators to climb up and down, and is not easy to slip, saving time and effort. Therefore, a safe and labor-saving valve switching process can be achieved, which can effectively reduce the difficulty of valve switching and improve the valve switching efficiency.
[0067] Although in Figure 1-Figure 2 In the illustrated embodiment, the length of the support rod 1 of the valve switching tool 10 is not adjustable, but it should be understood that in other embodiments not shown, the support rod 1 can be constructed to be adjustable in length to further expand the scope of application of the valve switching tool 10 and further improve the switching efficiency of the valve.
[0068] In addition, although Figure 1-Figure 2 In the illustrated embodiment, no anti-slip portion is provided on the handle 3 of the valve opening and closing tool 10, but it should be understood that in other embodiments not shown, anti-slip portions such as anti-slip grooves may be provided on the handle 3 to further facilitate the opening and closing of the valve.
[0069] The above description is only an exemplary embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
