Description

Technical Field

[0001] This invention relates to the field of maintenance and operation, and in particular to a portable valve switching auxiliary device with multiple modes. Background Technology

[0002] Chemical plants and power plants contain numerous valves used to control fluid transport, ensuring that fluids operate according to design conditions or change operating conditions, thus providing a reliable guarantee for the normal operation of the plant. When abnormal situations occur, valves need to be closed or opened to slow down the abnormal process; when the plant system needs to be shut down for maintenance, valves also need to be closed or opened to form an effective isolation boundary, ensuring the safety of workers and personnel within the area.

[0003] Due to cost and equipment importance considerations, large manual valves are present in factories such as chemical plants, power plants, water treatment plants, and paper mills. These manual valves are normally in a fixed open or closed position; however, in cases of anomalies or isolation as described above, it is necessary to operate these valves.

[0004] These large manual valves require a large torque to operate or require too many manual cranking turns, making them difficult to open and close. Many require the combined efforts of two or more people to operate them smoothly.

[0005] Current technologies primarily increase torque by increasing the radius of the valve's rotating disc, but this is limited by product size and installation requirements and cannot effectively solve problems such as labor-intensive and slow operation. The main drawbacks are as follows:

[0006] 1. The opening and closing torque is large, which requires high physical strength from the operator, and often makes it difficult to operate the valve to the target state smoothly.

[0007] 2. The valve has many turns, the operation time is long, and the system cannot be quickly restored to a safe state; it consumes a lot of manpower and time, the labor intensity is high, and it affects the progress of other work.

[0008] 3. If valves in the radioactive area of ​​the power plant are involved, the long time and large workload will result in a high radiation dose.

[0009] 4. Large manual valves are generally operated during major overhauls. Major overhauls are time-sensitive and demanding. If the valves cannot meet the requirements in a short period of time, it will affect the progress of the main overhaul.

[0010] The need is to address the issues of high torque and long operation time associated with large manual valves in factories, while considering economic factors, without altering the factory system design, and retaining existing manual valves, thereby improving the operator experience. Currently, there are technical solutions using portable electric or pneumatic devices to provide a power source to drive the valve rotation (Patent No.: CN202120102178.2 A Valve Opening and Closing Device); however, regarding enhancing manual operation to achieve multiple modes such as high speed and high torque for valve opening and closing, a review of existing patents and research papers reveals no suitable manual auxiliary devices.

[0051] The left side of the first adapter wheel 5 is provided with a connecting and fixing clip 6 and a fixing member 9 thereon, and the planetary carrier 3 is connected to the right side of the first adapter wheel 5;

[0052] The connecting and fixing clamp 6 and the fixing member 9 thereon are used to fix the target valve rotating disc and restrict the radial and axial movement of the valve disc.

[0053] The connecting and fixing clip 6 provided on the left side of the first adapter wheel 5 is used when the first adapter wheel 5 and the target valve wheel are fixed as an output wheel;

[0054] Preferably, the left side of the first adapter wheel 5 is provided with 3 to 10 connecting and fixing clips 6, which are evenly arranged on the same circumference;

[0055] The first adapter wheel 5 is provided with a groove, and the bottom of the connecting and fixing clip 6 is movably connected to the left side of the first adapter wheel 5. After being flipped, it is stored in the groove.

[0056] The connecting and fixing clip 6 is also connected to a fixing component 9. The fixing component 9 can be a hook-shaped structure, a claw-shaped structure, or a fixing strap.

[0057] The right side of the second adapter wheel 7 is provided with a connecting and fixing clip 6 and a rotating connecting rod 10.

[0058] The connecting and fixing clamp 6 and the fixing member 9 thereon are used to fix the target valve rotating disc and restrict the radial and axial movement of the valve disc.

[0059] The right side of the second adapter wheel 7 is provided with 3 to 10 connecting and fixing clips 6, which are evenly arranged on the same circumference.

[0060] The connecting and fixing clip 6 provided on the right side of the second adapter wheel 7 is used when the second adapter wheel 7 and the target valve wheel are used as output wheels;

[0061] The second adapter wheel 7 is provided with a groove, and the bottom of the connecting and fixing head 6 is movably connected to the right side of the second adapter wheel 7. After being flipped, it is stored in the groove.

[0062] The connecting and fixing clip 6 is also connected to a fixing component 9. The fixing component 9 can be a hook-shaped structure, a claw-shaped structure, or a fixing strap.

[0063] The fixing component 9 has a folding function and can be folded and stored in the connecting fixing head 6 when not in use.

[0064] The planetary gear mechanism is located between the first adapter wheel 5 and the second adapter wheel 7;

[0065] The planetary gear mechanism includes planetary gears 2, planet carriers 3, sun gears 4, and internal gear housings 1;

[0066] The planetary carrier 3 is connected to the right side of the first adapter wheel 5; the sun wheel 4 is connected to the left side of the second adapter wheel 7.

[0067] The second adapter wheel 7 and the sun wheel 4 are permanently fixed by a rigid connection, and the first adapter wheel 5 and the planet carrier 3 are permanently fixed by a rigid connection.

[0068] The planetary gears are arranged in three parts, and their relative positions are symmetrically fixed by the planetary carrier 3.

[0069] like Figure 3 and Figure 4 As shown, the sun gear, planet gears, and internal gear housing of the planetary gear mechanism employ inter-tooth meshing;

[0070] The operating lever 8 is connected to the outer side of the internal gear seat 1;

[0071] There are 2 to 5 operating levers, which are radially and evenly arranged on the outer circumference of the internal gear seat 1.

[0072] The rotating connecting rod 10 is located on the outer circumference of the connecting and fixing clamp 6 for easy operation.

[0073] When a large torque is required to open or close a large valve, the internal gear seat is fixed by the operating lever, and the operator rotates the rotating connecting rod set on the second adapter wheel, thereby transmitting the rotational torque input to the sun gear. Then, through the speed change of the planetary gear mechanism, the torque is transmitted to the planetary support, thereby driving the target valve wheel fixed on the first adapter wheel to rotate, so as to achieve the effect of opening or closing the valve.

[0074] When a higher speed or faster valve rotation is required, the first adapter wheel is fixed in place by a fixing device on the first adapter wheel. The operator rotates the operating lever set on the internal gear seat, and rotates the planetary gear through gear meshing. The speed is increased by the gear ratio, and the rotation is transmitted to the sun gear and the second adapter wheel, thereby driving the target valve wheel fixed on the second adapter wheel to rotate and obtain a higher speed.

[0075] This invention provides a portable valve switching auxiliary device with multiple modes, which effectively solves the problem of difficult switching of large manual valves and valves with multiple opening and closing turns, which are common in factories such as chemical plants, power plants, water treatment plants, and paper mills. For valves requiring large torque and fast operation, a single device can solve the problems of large torque and long operation time of large manual valves in factories, thus improving the operator's experience.

[0076] The following describes two operating modes of the portable valve switching auxiliary device with multiple modes of the present invention:

[0077] 1. High-torque switching valve

[0078] In this state, the internal gear seat 1 of the planetary gear mechanism is fixed, the sun gear 4 acts as the driving gear, the transmission ratio ranges from 2.5 to 5, and the torque input direction and output direction are consistent.

[0079] 1) The connecting and fixing clips 6 on the first adapter wheel 5 are all unfolded and fit into the target valve rotating disc, restricting the radial movement of the target valve disc.

[0080] 2) The fixed component 9 is deployed to fix and restrict the axial movement of the target valve wheel disc.

[0081] 3) The internal gear seat 1 of the planetary gear mechanism is connected to the site fixing device via an extension rod.

[0082] 4) The connecting and fixing clips 6 and fixing components 9 on the second adapter wheel 7 are folded and stowed.

[0083] 5) The operator manually controls the rotating linkage 10 to rotate the second adapter wheel 7 in the desired direction.

[0084] 6) This reduces speed and increases torque through gear reduction, causing the target valve to open or close in the desired direction. It significantly increases operating torque, with a maximum transmission ratio of approximately 20, a planetary gear transmission ratio of 2.5-5, and a second adapter gear transmission ratio of 3-4.

[0085] 2. High-speed switching valve

[0086] In this state, the planet carrier 3 of the planetary gear mechanism is fixed, the internal gear seat 1 acts as the driving gear, the transmission ratio ranges from 0.25 to 0.67, and the torque input direction and output direction are opposite.

[0087] 1) The connecting and fixing clips 6 on the second adapter wheel 7 are all unfolded and fit with the target valve rotating disc, restricting the radial movement of the target valve disc.

[0088] 2) The fixed component 9 can be unfolded to fix and restrict the axial movement of the target valve wheel disc.

[0089] 3) The fixing head 6 connected to the first adapter wheel 5 is connected to the fixed point of the site through an auxiliary device.

[0090] 4) The fixing components 9 on the first adapter wheel 5 are all folded up.

[0091] 5) The operator manually controls the operating lever 8 to rotate the internal gear seat 1 in the desired direction.

[0092] 6) This, through gear-driven speed increase transmission, drives the target valve to open or close in the desired direction. It can significantly increase the valve opening or closing speed, with a maximum speed change of approximately four times.
