Description

Technical Field

[0001] The present invention relates to the field of valve tools, and in particular to a valve opening and closing tool device. Background Art

[0002] In the daily operation of thermal power plants and chemical plants, manual valves and electric valves are widely used. The opening and closing operations of manual valves and electric valves usually need to be carried out with the help of an F wrench. In actual work, the implementation of one-time safety measures or equipment operations often involves various types of valves. However, the size of the F wrench is fixed, and operators have to carry multiple F wrenches of different sizes to meet the operation requirements of different valves. F wrenches of different sizes usually have different weights. In particular, large-sized F wrenches are often relatively heavy, which undoubtedly increases their physical burden. Especially when frequent movement or climbing of equipment is required, it will greatly consume physical strength and reduce work efficiency. In order to pursue operational convenience, some operators will choose to use large-sized F wrenches to open small-sized valves. Since the torque of the large-sized F wrench does not match that of the small valve seriously, it is extremely easy to cause damage to the valve during the operation process, such as causing faults such as valve stem bending, handwheel breakage, and copper nut damage of the valve, which has a fatal impact on the life of the valve and will also increase the equipment maintenance cost. Summary of the Invention

The annular member is clamped on the valve through the three tooth engaging members, and the annular member is rotated by the wrench, and the valve rotates with the annular member to realize the opening and closing of the valve. When it is necessary to increase the torque, the tooth engaging members can be fixedly installed on the extension part.

[0024] Embodiment 1

[0025] Referring to Figures 1-3 , this embodiment provides a valve opening and closing tool device, including an annular member 1 and an annular block 2. A wrench 11 is provided on the annular member 1; a tooth engaging portion 3, the tooth engaging portion 3 includes at least three connecting members 31 provided on the annular member 1, and a tooth engaging member 32 is provided on the connecting member 31; an extension portion 4, which is provided on the annular member 1, and the extension portion 4 is provided with at least three; the tooth engaging member 32 is fixedly installed at a corresponding position of the connecting member 31 according to the torque of the valve. The annular member 1 is stuck on the valve through the three tooth engaging members 32. By rotating the annular member 1 through the wrench 11, the valve rotates along with the annular member 1 to realize the opening and closing of the valve. When it is necessary to increase the torque, the tooth engaging member 32 can be fixedly installed on the extension portion 4.

[0026] Specifically, the annular member 1 and the wrench 11 are tightly combined by a fixed connection method, and the annular block 2 is fixedly connected to the annular member 1 through the connecting member 31, ensuring the overall stability and reliability of the device during operation;

[0027] During use, according to the torque requirement of the valve, the three detent members 32 are respectively installed on the corresponding three connecting members 31. The whole device is clamped on the valve through the detent members 32. The whole device is rotated by the wrench 11, so that the valve rotates along with the annular member 1. By providing an additional lever force, it helps the operator to open or close the valve more easily. When the handwheel of the valve is large in size, the three detent members 32 are respectively installed on the corresponding three extension parts 4 to increase the torque, so that the device can more effectively meet the operation requirements of large-size valves, ensure the smooth opening or closing of the valve, enable the device to adapt to valves with different sizes and torque requirements, improve the practicability, and effectively avoid faults such as valve stem bending, handwheel fracture, and copper nut damage caused by inappropriate torque, greatly extending the service life of the valve and reducing the equipment maintenance cost;

[0028] Embodiment 2

[0029] Refer to Figures 1-2 , what is different about this embodiment from the first embodiment is that the three connecting members 31 and the three extension parts 4 are both arranged in an annular array; the connecting member 31 includes a connecting plate 311 provided on the annular member 1, and at least two first threaded holes 312 are provided on the connecting plate 311;

[0030] Specifically, the three connecting members 31 and the three extension parts 4 arranged in an annular array make the device more stable during operation and the force is more evenly distributed. The connecting plate 311 is fixedly connected to the annular block 2 and the annular member 1. The two first threaded holes 312 are symmetrically arranged, and the two first threaded holes 312 correspond to different torque requirements, so as to adapt to two different sizes of valves;

[0031] The detent member 32 includes a bolt 321 provided in the first threaded hole 312, a nut 322 is provided on the bolt 321, and the bolt 321 is threadedly connected to the first threaded hole 312;

[0032] Specifically, the nut 322 is threadedly connected to the bolt 321. When the three bolts 321 are connected to the three connecting plates 311 through the first threaded holes 312, it is necessary to ensure that the three bolts 321 are located in the first threaded holes 312 on a circumference. The thread on the bolt 321 is a good detent and plays an anti-slip role, ensuring that the device is not easy to slip during operation, thereby ensuring the reliability of the operation;

[0033] A first groove 411 is opened on the annular member 1, and a second threaded hole 412 is provided on the groove;

[0034] Specifically, there are three first grooves 411, and the three first grooves 411 are distributed in an annular array. The second threaded holes 412 are threadedly connected to the bolts 321. The second threaded holes 412 correspond to three different torques and are adapted to valves of the third size. This design further expands the application range of the device, enabling it to adapt to more valves with different sizes and torque requirements;

[0035] During use, the operator, according to the torque requirement of the valve, places the bolt 321 in a corresponding first threaded hole 312 or second threaded hole 412 on a circumference, threadedly connects the bolt 321 with the first threaded hole 312 or the second threaded hole 412, and then threadedly connects the nut 322 with the bolt 321 to fix the bolt 321 to the connecting plate 311 or the annular member 1. Subsequently, the bolt 321 is clamped on the valve, and then the annular member 1 is rotated by the wrench 11 to drive the entire device and the valve to rotate. With the provided additional leverage, it helps the operator to more easily open or close the valve;

[0036] Through the first threaded holes 312 and the second threaded holes 412, the device can adapt to valves with different sizes and torque requirements, enabling the operator to not need to carry multiple F wrenches and only use the on-site bolts 321 and nuts 322 to easily open and close the valve. At the same time, by changing the fixing positions of the bolts 321 and nuts 322, the operator can select an appropriate torque according to the actual requirements of the valve, avoiding the risks that may be brought by using a large F wrench to open a small valve, thus effectively avoiding malfunctions such as bent valve stems, broken handwheels, and damaged copper nuts, and significantly extending the service life of the valve and reducing the equipment maintenance cost;

[0037] Embodiment 3

[0038] Refer to Figures 3-4 This embodiment is different from the second embodiment in that the extension part 4 includes an extension arm 41 provided on the annular member 1, and a third threaded hole 42 and a fourth threaded hole 43 are provided on the extension arm 41; the aperture of the fourth threaded hole 43 is larger than that of the third threaded hole 42;

[0039] Specifically, there are three third threaded holes 42, and the three threaded holes are equidistantly distributed. When the handwheel of the valve is too large, a large-sized bolt 321 is used and threadedly connected with the fourth threaded hole 43, enabling the device to adapt to larger-sized valves;

[0040] The annular member 1 is provided with a second groove 413 adapted to the extension arm 41, and the extension arm 41 is located in the second groove 413;

[0041] Specifically, the corresponding third threaded holes 42 correspond to the second threaded holes 412, enabling the extension arm 41 to be fixedly connected to the annular member 1 through shorter bolts 321 and nuts 322, and the second threaded holes 412 communicate with the second grooves 413;

[0042] In use, in conjunction with Embodiment 2, when the handwheel of the valve is of a large size, the three extension arms 41 are respectively located in the corresponding second grooves 413, so that the corresponding third threaded holes 42 are aligned with the second threaded holes 412. Then, the extension arms 41 are fixedly connected to the annular member 1 through bolts 321 and nuts 322. Subsequently, according to the torque requirement of the valve, the threads are located in one of the third threaded holes 42 or the fourth threaded holes 43 on the corresponding circumference, so that the bolts 321 are threadedly connected to the third threaded holes 42 or the fourth threaded holes 43, and then the nuts 322 are threadedly connected to the bolts 321 to fix the bolts 321 to the extension arms 41. Subsequently, the bolts 321 are clamped on the valve, and the annular member 1 is rotated by the wrench 11 to drive the device and the valve to rotate, realizing the opening or closing of the valve;

[0043] Through the design of the extension arms 41, the device can further adapt to valves with different sizes and torque requirements, significantly improving the practicability and applicability. At the same time, this design not only expands the applicable range of the device, but also provides greater flexibility for the operator, enabling them to more efficiently complete various valve operation tasks;

[0044] During actual carrying, the extension arms 41 can be directly fixedly installed on the annular member 1 through shorter bolts 321 and nuts 322 to form a compact overall structure for easy carrying. It can also be quickly deployed and put into use after arriving at the operation site, greatly improving work efficiency;

[0045] In addition, the detachable design of the extension arms 41 allows the extension arms 41 to be easily disassembled when not in use, greatly reducing the volume of the device, facilitating storage and transportation, reducing the risk of damage to the device during transportation, and increasing the service life of the device;

[0046] The remaining structure is the same as that of Embodiment 2

[0047] Embodiment 4

[0048] Refer to Figures 5-6 This embodiment is different from the third embodiment in that the annular member 1 is provided with a chute 414 adapted to the extension arm 41, and the extension arm 41 is slidably connected to the chute 414; a limiting groove 415 is formed in the side wall of the extension arm 41, and a limiting block 416 is arranged in the chute 414, and the limiting block 416 is slidably connected to the limiting groove 415;

[0049] Specifically, the three sliding grooves 414 are distributed in an annular array. There are two limiting grooves 415, and the two limiting grooves 415 are symmetrically arranged. There are two limiting blocks 416, and the two limiting blocks 416 are symmetrically arranged. The limiting blocks 416 are arranged in a "T" shape. Through the cooperation of the "T"-shaped limiting blocks 416 and the limiting grooves 415, the expansion arm 41 can slide smoothly in the sliding groove 414, and the second threaded hole 412 communicates with the sliding groove 414;

[0050] During use, in conjunction with Embodiment 3, when the handwheel of the valve is of a large size, according to the torque requirement of the valve, the three expansion arms 41 are toggled so that the expansion arms 41 slide away from the annular member 1 to a suitable position through the limiting blocks 416 and the limiting grooves 415, and then the thread is located in one of the threaded holes three 42 or threaded holes four 43 of the corresponding circumference, so that the bolt 321 is threadedly connected with the threaded hole three 42 or the threaded hole four 43, and then the nut 322 is threadedly connected with the bolt 321 to fix the bolt 321 to the expansion arm 41. Subsequently, the bolt 321 is stuck on the valve, and the annular member 1 is rotated by the wrench 11 to drive the device and the valve to rotate, realizing the opening or closing of the valve;

[0051] After the bolt 321 is stuck on the valve, a restriction is formed on the expansion arm 41, making it impossible for the expansion arm 41 to retract or expand at will. Through the sliding connection method, the device can further adapt to valves with different sizes and torque requirements, greatly improving its practicability and flexibility. At the same time, through the reasonable layout of the sliding grooves 414 and the limiting blocks 416, the device is more stable during operation, the force is more uniform, and the reliability and safety of the operation are significantly improved;

[0052] The remaining structure is the same as that of Embodiment 2.

[0053] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
