Description

Technical Field

[0001] The utility model relates to the technical field of valves, and particularly to a valve switch tool for impacting a handwheel. Background Technique

[0002] In modern industrial production, with the expansion of production scale and the increase of process complexity, the pipeline layout in production devices has become increasingly complex, which directly leads to a large number of valves being installed in remote positions that are difficult to directly reach, such as inside deep wells and under high-altitude platforms in restricted spaces. The operation of these valves is crucial for maintaining the stability and safety of the production process. However, traditional operation methods face many challenges.

[0003] First of all, for these remote valves, operators usually need to manually open and close them by means of scaffolding erection or entering restricted spaces (such as deep wells and high-altitude platforms). This method is not only inefficient, increasing labor costs and time costs, but also has significant safety risks. The process of scaffolding erection and dismantling is cumbersome, and working at high altitudes or in narrow spaces is extremely prone to safety accidents such as falling and collision. At the same time, the working environment in restricted spaces is often harsh, with poor ventilation and insufficient light, further increasing the operation difficulty and safety risks.

[0004] Secondly, in order to improve this situation, some improvement measures have been taken traditionally, such as adding operation platforms. Although this measure solves the problem of inconvenient operation to a certain extent, its limitations are also obvious. On the one hand, implementing such transformations in multiple places involves a large amount of work and high costs, and for large enterprises, the overall transformation cost may be unacceptable; on the other hand, due to the complex pipeline layout and a large number of valves, traditional operation methods not only occupy valuable space resources but may also have an adverse impact on the layout and aesthetics of the production site.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment 1

[0031] Figure 1 It is a schematic diagram of the overall structure of a valve switch tooling with an impact handwheel according to an embodiment of the present utility model; Figure 2 It is a schematic diagram of the handwheel structure according to an embodiment of the present utility model; Figure 3 It is a schematic diagram of the disc structure according to an embodiment of the present utility model. As Figures 1 - 3 shown, according to an embodiment of the present utility model, a valve switch tooling with an impact handwheel includes: a handwheel 1, a transmission shaft 2, a telescopic rod 3, and a disc 4;

[0032] The transmission shaft 2 is fixed at the center of the handwheel 1, and the transmission shaft 2 is fixedly connected to the disc 4 through the telescopic rod 3. A claw 5 for fixedly connecting with the valve is arranged at the bottom of the disc 4;

[0033] The length of the telescopic rod 3 can be adjusted according to the actual working conditions.

[0034] In this embodiment, the valve switch tooling of the impact handwheel achieves efficient operation and flexible adaptability through a precisely designed connection relationship. The handwheel 1, as the main operating component, has a transmission shaft 2 firmly fixed at its center, ensuring the direct transmission of the rotational force. The transmission shaft 2 is further tightly connected to the disc 4 through a telescopic rod 3. This connection method is not only stable but also enables the tooling to adapt to the valve operation requirements at different distances through the flexible adjustment of the telescopic rod 3. The disc 4, as one of the key components of the tooling, is ingeniously provided with a plurality of claws 5 at its bottom. These claws 5 can be tightly fixed on the valve, ensuring that the valve can be driven to rotate together when the handwheel 1 rotates. The connection relationship of the entire tooling is compact and efficient, ensuring both the stability of the operation and the improvement of work efficiency.

[0035] The utility model realizes the convenient and efficient operation of the valve switch; the design of the telescopic rod enables the tooling to adapt to valves at different distances, greatly improving the versatility and flexibility of the tooling. The stable connection relationship and precise component cooperation of the utility model ensure the stability and accuracy of the operation, avoiding valve damage or leakage problems caused by improper operation.

[0036] According to an embodiment of the utility model, a sleeve 6 is fixedly connected to the handwheel 1;

[0037] The transmission shaft 2 is installed inside the sleeve 6; the handwheel 1 drives the transmission shaft 2 to rotate by driving the sleeve 6 to rotate.

[0038] Preferably, a sleeve boss 61 is provided on the upper part of the sleeve 6, and a transmission boss 21 that matches the position and shape of the sleeve boss 61 is provided on the lower part of the transmission shaft 2.

[0039] In this embodiment, the function of the impact handwheel is realized by the rotation of the sleeve 6 welded to the handwheel 1 and the transmission shaft 2. The inner circle of the sleeve 6 is provided with 2 sleeve bosses 61 along the circumference, and the outer circle of the transmission shaft 2 is provided with 2 transmission bosses 21 along the circumference. The transmission shaft 2 is installed inside the sleeve 6, and the sleeve 6 can rotate around the transmission shaft 2. The sleeve 6 and the handwheel 1 are connected by welding. Rotating the handwheel 1 drives the sleeve 6 to rotate. When it rotates to a certain angle, the sleeve boss 61 contacts the transmission boss 21. At this time, the sleeve 6 drives the transmission shaft 2 to rotate and drives the disc 4 to rotate through the telescopic rod 3. The rotation of the disc 4 drives the valve handwheel to rotate through the claws 5 to realize the opening and closing of the valve.

[0040] The utility model realizes that when the handwheel rotates to a specific angle, the sleeve drives the transmission shaft and subsequent components to rotate by welding a sleeve on the handwheel and setting a matching boss structure between the sleeve and the transmission shaft, thereby controlling the opening and closing of the valve. This design not only improves the accuracy and stability of operation, but also simplifies the transmission structure, making the entire valve opening and closing tooling more compact and efficient. The utility model significantly improves the convenience and reliability of valve operation, and reduces the operation difficulty and failure rate.

[0041] According to an embodiment of the utility model, the cross-section of the handwheel 1 in the horizontal direction is circular; a non-slip layer is provided on the surface of the handwheel 1.

[0042] In this embodiment, the handwheel 1, as the main operating component of the valve opening and closing tooling, has a circular cross-section in the horizontal direction, which not only conforms to ergonomics, facilitates the operator to hold and rotate, but also ensures the stability and smoothness during the rotation process. The surface of the handwheel 1 is carefully provided with a non-slip layer, and this design fully considers the safety and comfort during the operation process. The non-slip layer is made of high-quality materials and has good wear resistance and anti-slip performance. Even in a humid or oily environment, it can ensure a firm contact between the operator's hand and the handwheel, effectively preventing operation errors or safety accidents caused by hand slipping. At the same time, a sleeve 6 is firmly fixed at the center of the handwheel 1, and a transmission shaft 2 is installed inside the sleeve 6. This precise connection relationship ensures the smooth transmission of the rotational force.

[0043] Through the design of the circular handwheel and the non-slip layer, the utility model significantly improves the operation safety and comfort of the valve opening and closing tooling, and ensures the stability and accuracy of the operation.

[0044] According to an embodiment of the utility model, the telescopic rod 3 includes: a first extension rod 31 and a second extension rod 32 which are sleeved and connected;

[0045] The length of the telescopic rod 3 is adjusted by adjusting the sleeved length of the first extension rod 31 and the second extension rod 32.

[0046] Preferably, an external thread is provided on the outer wall of the first extension rod 31, and an internal thread matching the external thread is provided on the inner wall of the second extension rod 32.

[0047] Preferably, a plurality of matching through holes are equidistantly provided on the outer walls of the first extension rod 31 and the second extension rod 32, and the adjusting bolt sequentially passes through the through holes on the second extension rod 32 and the through holes on the first extension rod 31 to fix the relative positions of the first extension rod 31 and the second extension rod 32.

[0048] In this embodiment, the telescopic rod 3 is formed by sleeving and connecting the first extension rod 31 and the second extension rod 32. This design allows the operator to adjust the rod length according to the actual working conditions. The outer wall of the first extension rod 31 is specially made with external threads, while the inner wall of the second extension rod 32 is correspondingly provided with internal threads matching the external threads. By rotating the two, the adjustment of the sleeved length can be achieved. To further fix the adjusted length, a plurality of matching through holes are equidistantly arranged on the outer walls of the first extension rod 31 and the second extension rod 32. The adjusting bolt can pass through these through holes to firmly lock the two rods in the required position.

[0049] The utility model realizes the convenience and stability of length adjustment through the dual mechanisms of threaded sleeving and through hole locking, enabling the valve switch tooling to flexibly adapt to different operating environments and distance requirements, and improving work efficiency and adaptability.

[0050] According to an embodiment of the utility model, a flange 33 is provided at the bottom of the telescopic rod 3;

[0051] The fixing bolt 7 passes through the disc 4 and the flange 33 to connect the telescopic rod 3 and the disc 4.

[0052] Preferably, a plurality of claw jaws 5 are provided and evenly distributed on the outer periphery of the bottom of the disc 4.

[0053] In this embodiment, a flange 33 is specially designed at the bottom of the telescopic rod 3. This structure not only enhances the stability of the rod body but also facilitates the connection with the disc 4. By passing the fixing bolt 7 through the disc 4 and the flange 33, a tight and reliable connection between the telescopic rod 3 and the disc 4 is achieved. In addition, a plurality of claw jaws 5 are evenly distributed on the outer periphery of the bottom of the disc 4. These claw jaws 5 are arranged at equal intervals to ensure uniform force during rotation and effectively transmit the rotational power from the telescopic rod 3 to the valve handwheel.

[0054] The utility model simplifies the connection process between the telescopic rod and the disc through the combination of the flange and the fixing bolt, enhances the stability and durability of the connection; the design of the evenly distributed claw jaws at the bottom of the disc ensures the balanced transmission of rotational power and improves the overall stability and operation efficiency of the valve switch tooling.

[0055] The device of the utility model is a valve switch tooling for impacting the handwheel. When encountering large resistance in opening or closing the valve, the handwheel can be rotated to drive the sleeve to impact the transmission shaft. After several impacts, the valve opening torque is increased to open or close the valve. At the same time, the telescopic extension rod is used to switch the valve at a long distance. It has the advantages of convenient movement, wide application range, large switching torque, reliable grasping and explosion protection.

[0056] Embodiment 2

[0057] Such asFigures 1 - 3 As shown, according to an embodiment of the present utility model, a valve switch tooling for an impact handwheel, the function of the impact handwheel is realized by the rotation of the sleeve 6 welded on the handwheel 1 and the transmission shaft 2. There are 2 sleeve bosses 61 along the circumference of the inner ring of the sleeve 6, and 2 transmission bosses 21 along the circumference of the outer ring of the transmission shaft 2. The transmission shaft 2 is installed inside the sleeve 6, and the sleeve 6 can rotate around the transmission shaft 2. The sleeve 6 and the handwheel 1 are connected by welding. Rotating the handwheel 1 drives the sleeve 6 to rotate. When rotated to a certain angle, the sleeve boss 61 of the sleeve 6 contacts the transmission boss 21 of the transmission shaft 2. At this time, the sleeve 6 drives the transmission shaft 2 to rotate and drives the disc 4 to rotate through the telescopic rod 3. The rotation of the disc 4 drives the valve handwheel to rotate through the claw 5 to realize the opening and closing of the valve. When it is difficult to open and close the valve, the handwheel 1 can be quickly rotated to use the impact force generated by the handwheel 1 to strike the transmission boss 21, so that the transmission shaft 2 rotates and drives the disc 4 to realize the opening and closing of the valve.

[0058] The device of the present utility model directly couples the sleeve welded on the handwheel with the transmission shaft, and uses the contact and impact force between the sleeve boss and the transmission boss to realize efficient force-increasing transmission; the structure design of the present utility model is compact, which is not only convenient for carrying and quickly deploying in various working environments, but also significantly broadens the application field and is applicable to various valve opening and closing scenarios. The present utility model is easy to maintain and replace parts, greatly reducing the maintenance cost and time, and ensuring the stability and reliability of long-term operation. The present utility model shows remarkable technical effects in improving operation efficiency, enhancing equipment adaptability and maintenance convenience.
