Description

Technical Field

[0001] This invention relates to the field of alloy valves and their manufacturing technology, specifically to a micro-alloyed low-alloy valve and its drilling device. Background Technology

[0002] Microalloyed low-alloy valves are high-performance valves manufactured using microalloying technology. The core of this technology lies in the precise addition of extremely small amounts (usually <0.1% in total) of "microalloying elements" such as niobium, vanadium, and titanium to ordinary low-alloy steel. These elements, through a special heat treatment process, form nanoscale reinforcing particles inside the steel and refine the steel's grain structure. This technology can significantly improve the strength, toughness, corrosion resistance, and wear resistance of valves at a very low cost, while maintaining good weldability and machinability. There are various types of valves available, including butterfly valves. During operation, the side of the butterfly valve plate facing the impact of the medium (usually the downstream side) experiences the strongest fluid impact force, shear force, and turbulent disturbance. This makes this area highly susceptible to erosion wear, fatigue cracks, and may also cause problems such as valve plate vibration, premature failure of the sealing surface, and increased driving torque. Furthermore, existing drilling equipment used for machining alloy valves typically employs a top-down pressure method when machining valves. Valve structures are often irregular (such as valve bodies and valve covers). When applying pressure from top to bottom, if the support is insufficient, the workpiece may vibrate or elastically deform due to the pressure, leading to problems affecting the positional accuracy of the hole. Therefore, a micro-alloyed low-alloy valve and its drilling device are needed to improve the above problems. Summary of the Invention

[0020] In this embodiment, specific references Figure 1 A rubber diaphragm 810 is installed on the front side of the brake pad 7. A connecting pipe 801 is located inside the rubber diaphragm 810. One end of the connecting pipe 801 is connected to a connecting pipe 803 via an adapter. A connecting sleeve 807 is installed in the middle of one side of the brake pad 7 where the rubber diaphragm 810 is installed, and a connecting pipe 803 connects to the inside of the connecting sleeve 807. A connecting rope 809 is provided at the bottom of the inner cavity of the connecting sleeve 807. A rubber block 813 is connected to one end of the connecting rope 809 away from the connecting sleeve 807. A sliding post 808 is installed on the side of the rubber block 813 away from the connecting rope 809. The side wall of the sliding post 808 is in contact with and fits against the inner wall of the connecting sleeve 807. The sliding column 808, on the side furthest from the connecting sleeve 807, is connected to the middle of the rubber diaphragm 810. The design of the connecting rope 809 prevents the sliding column 808 from falling out of the connecting sleeve 807 and is used to pull the sliding column 808.

[0021] In this embodiment, specific references Figure 1 - Figure 7 A worm gear 607 is provided inside the rotating shaft 606, and a sliding column 805 is slidably installed inside the worm gear 607. A rubber ring 806 is sleeved on the side wall of the sliding column 805. A plug-in post 804 is installed on the bottom surface of the sliding post 805. The plug-in post 804 penetrates the bottom surface of the inner cavity of the worm gear 607 and extends to the outside. A connecting pipe 802 is connected to the upper side wall of the rotating shaft 606, and the other end of the connecting pipe 802 is connected to the connecting pipe 801. Among them, the rotating shaft 603 is located on the outside of the mounting box 601 and a rotating wheel 604 is installed. When adjusting the brake plate 7, rotating the rotating wheel 604 drives the rotating shaft 603, worm 605, worm wheel 607 and brake plate 7 to rotate, thereby achieving the effect of adjusting the flow of medium inside the pipeline 5.

[0022] In this embodiment, specific references Figure 1 - Figure 14 A connecting block 609 is installed on the bottom surface of the rotating shaft 606. A connecting plate 610 is installed on the bottom surface of the connecting block 609. An installation groove 608 is opened on the connecting plate 610.

Pulling down the two fixed ropes 814 causes the pull ring 815 to pull the connecting ring 811 and the plug-in post 804 upward. As the plug-in post 804 rises, the second limiting block 812 on the plug-in post 804 abuts against the first limiting block 611. The first limiting block 611 then compresses the spring 614 and retracts into the first mounting frame 613. When the second limiting block 812 is above the first limiting block 611, the first limiting block 611 resets under the action of the spring 614. The top surface of the first limiting block 611 contacts the bottom surface of the second limiting block 812, thus supporting the second limiting block 812 and the plug-in post 804.

[0023] In this embodiment, specific references Figure 1 - Figure 14A connecting ring 811 is installed on the lower side wall of the plug post 804. A pull ring 815 is symmetrically installed on the end face of the connecting ring 811. The pull ring 815 passes through the connecting disc 610. A fixing rope 814 is connected to the side of the two pull rings 815 away from the connecting ring 811.

[0024] A drilling device for machining micro-alloyed low-alloy valves includes a working platform 1, and a drilling assembly 2 is installed on the top surface of the inner cavity of the working platform 1. The drilling assembly 2 includes a linear module 201. The linear module 201 is symmetrically installed on the top surface of the inner cavity of the working platform 1. An electric telescopic rod 204 is installed on the bottom surface of the moving end of the linear module 201. A rotary motor 202 is installed on the telescopic end of the electric telescopic rod 204. A drill bit 203 is installed on the power output shaft of the rotary motor 202. The device includes a control panel (not shown in the figure), which controls the synchronous operation of the rotary motor 202, linear module 201, electric telescopic rod 1 204, electric telescopic rod 2 407 and two motors 2 3. The control methods described above are all existing known electrical equipment, and all can be purchased and used directly on the market. Their structure, circuit and control principle are all existing known technologies. The specific structure, circuit and control principle will not be described in detail here. Furthermore, the drilling assembly 2 can adopt the linear module provided in the announcement number CN116633110B, which will not be elaborated here.

[0025] In this embodiment, specific references Figure 1 - Figure 14 On the worktable of the work platform 1, motors 2 and 3 are symmetrically installed. Positioning components 4 are respectively installed on the power output shafts of the two motors 2 and 3. The positioning components 4 include mounting frames 2 and 402. Mounting frames 2 and 402 are installed on the power output shafts of motors 2 and 3. Mounting blocks 401 are installed on the side of mounting frames 2 and 402 away from mounting blocks 401. The mounting block 401 has a sliding groove 404, in which a sliding block 403 is slidably mounted. Positioning blocks 405 are respectively mounted on the left and right sides of the sliding block 403. The positioning blocks 405 are arc-shaped, and rubber pads 406 are mounted on the arc-shaped surface of the positioning blocks 405. An electric telescopic rod 407 is installed in the inner cavity of the sliding groove 404, and the telescopic end of the electric telescopic rod 407 is connected to the sliding block 403. Among them, during the use of the device, the pipeline 5 is placed inside the working platform 1. Subsequently, the electric telescopic rod two 407 is started to drive the sliding block 403 and the positioning block 405 to move, so that the rubber pad 406 abuts against the inner wall of the pipeline 5, realizing the positioning of the pipeline 5. Subsequently, the motor two 3 is started to drive the positioning component 4 and the pipeline 5 to rotate and turn over, realizing that when drilling processing needs to be carried out on the valve, it can be abutted and positioned from the inside of the pipeline 5, so as to adapt to valves with different apertures for positioning, and at the same time achieving the effect of facilitating the turning processing of the valve after positioning; Among them, the workbench surface of the working platform 1 is designed in a "square" shape, which is convenient for placing the pipeline 5 therein.

[0026] When a micro-alloyed low-alloy valve of this solution works, the device is installed at a designated position by using the flange on the pipeline 5. During installation, it is necessary to mainly face the rubber film 810 in the direction of the medium flow; Before introducing the medium, pull down the two fixing ropes 814 to drive the pull ring 815 to pull the connecting ring 811 and the plug post 804 to rise. As the plug post 804 rises, the second limiting block 812 on the plug post 804 abuts against the first limiting block 611. Subsequently, the first limiting block 611 compresses the spring 614 and contracts into the first installation frame 613. When the second limiting block 812 is above the first limiting block 611, under the action of the spring 614, the first limiting block 611 resets, and the top surface of the first limiting block 611 contacts the bottom surface of the second limiting block 812, realizing the function of supporting and limiting the second limiting block 812 and the plug post 804; Furthermore, during the upward movement of the plug post 804, the plug post 804 drives the first sliding column 805 to move upward, thereby compressing the air flow in the worm wheel 607 and pushing it into the second connecting pipe 802. Subsequently, the air flow passes through the second connecting pipe 802, the first connecting pipe 801, the third connecting pipe 803 and the connecting sleeve 807, and finally pushes the rubber block 813 and the second sliding column 808 to move outward, thereby supporting the brake piece 7. The design of the connecting rope 809 prevents the second sliding column 808 from falling off the connecting sleeve 807; Subsequently, the flowing medium is introduced. The convex rubber film 810 disperses the impact of the flowing medium in the pipeline 5, greatly reducing the erosion wear on the key parts of the valve body and valve seat. It is especially suitable for micro-alloyed low-alloy materials, giving full play to its strength advantages, and achieving the effect of extending the service life of the valve under harsh working conditions; When drilling the flange on pipe 5, pipe 5 is placed inside the work platform 1. Then, the electric telescopic rod 407 is activated to move the sliding block 403 and the positioning block 405, so that the rubber pad 406 abuts against the inner wall of pipe 5, thereby positioning pipe 5. Then, the motor 3 is activated to drive the positioning component 4 and pipe 5 to rotate. This allows the valve to be positioned by contact from inside pipe 5 when drilling is required, thus adapting to valves of different diameters. At the same time, it facilitates the rotation of the valve after positioning.

[0027] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
