[0001] This utility model relates to the field of regulating valve technology, specifically a throttling regulating valve. Background Technology

[0002] A throttling control valve is a valve device that controls the flow rate and pressure of a medium by changing the cross-sectional area or length of the fluid passage. It plays a key regulatory role in industrial fluid control systems.

[0003] However, existing throttling control valves do not have the function of lubricating the connection between the valve stem and the valve body, which easily leads to excessive friction and affects their normal use. In addition, the handwheel in existing throttling control valves has the defect of being inconvenient to disassemble and assemble.

[0004] To address the aforementioned problems, this application proposes a throttling regulating valve to solve them. Utility Model Content

[0005] To address the problems of existing throttling control valves lacking lubrication at the valve stem-valve body connection and the inconvenience of disassembling and assembling the handwheel, the purpose of this utility model is to provide a throttling control valve.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a throttling regulating valve, including a regulating valve body and a handwheel, the regulating valve body is provided with a valve stem for cooperation, and the handwheel and the valve stem are detachably connected, the top of the regulating valve body is provided with a lubrication mechanism for cooperation with the valve stem, and the handwheel is provided with a docking mechanism for cooperation with the valve stem;

[0007] The lubrication mechanism includes a base cylinder, which is fixedly installed at the top of the regulating valve body. An oil pipe, which works with the valve stem and the regulating valve body, is connected to the base cylinder. An oil reservoir ring is connected to the top of the base cylinder and is movably sleeved on the outside of the valve stem. A countersunk hole is formed at the top of the oil reservoir ring, and a push rod is slidably inserted into the countersunk hole. An oil injection hole, which works with the countersunk hole, is formed on the oil reservoir ring. A sliding hole, which communicates with the countersunk hole, is formed on the oil reservoir ring, and the push rod is slidably inserted into the sliding hole. A push plate is fixedly connected to the top of the push rod, and a spring is fixedly installed at the bottom of the push plate. The bottom of the spring is fixedly connected to the inner wall of the countersunk hole. A piston is fixedly connected to the end of the push rod away from the spring, and the piston is movably inserted into the base cylinder, working in conjunction with the oil pipe.

[0008] Preferably, the docking mechanism includes a sliding plate, an inner groove on the handwheel, and the sliding plate slidably inserted into the inner groove. A second spring is fixedly installed on one side of the sliding plate, and the end of the second spring is fixedly connected to the inner wall of the inner groove. An insertion rod is fixedly installed on the other side of the sliding plate. An insertion hole is opened at the top of the valve stem, and the insertion rod can slide through the handwheel and slide into the insertion hole.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figures 1-4 As shown, this utility model provides a throttling regulating valve, including a regulating valve body 1 and a handwheel 2. The regulating valve body 1 is provided with a valve stem 3 for cooperation, and the handwheel 2 and the valve stem 3 are detachably connected. The top of the regulating valve body 1 is provided with a lubrication mechanism 4 for cooperation with the valve stem 3, and the handwheel 2 is provided with a docking mechanism 5 for cooperation with the valve stem 3.

[0020] The lubrication mechanism 4 includes a base cylinder 41, which is fixedly installed at the top of the regulating valve body 1. An oil pipe 42, which works in conjunction with the valve stem 3 and the regulating valve body 1, is connected to the base cylinder 41. An oil reservoir ring 43 is connected to the top of the base cylinder 41 and is movably sleeved on the outside of the valve stem 3. A countersunk hole 44 is formed at the top of the oil reservoir ring 43, and a push rod 45 is slidably inserted into the countersunk hole 44. An oil injection hole 49 is formed through the upper end of the oil reservoir ring 43, facilitating the introduction of lubricating oil into the oil reservoir ring 43. The oil reservoir ring 43 has a sliding hole 410 that communicates with the countersunk hole 44, and the push rod 45 is slidably inserted into the sliding hole 410. The sliding hole 410 is used to limit and guide the movement of the push rod 45. The top end of the push rod 45 is fixedly connected to the push plate 46, and the bottom end of the push plate 46 is fixedly installed with a spring 47. The bottom end of the spring 47 is fixedly connected to the inner wall of the countersunk hole 44, and the end of the push rod 45 away from the spring 47 is fixedly connected to the piston 48. The piston 48 is movably inserted into the bottom cylinder 41, and the piston 48 is used in conjunction with the oil pipe 42.

[0021] By adopting the above technical solution, when the handwheel 2 is connected to the valve stem 3, the push plate 46 will be pushed down synchronously, thereby pushing the push rod 45 and the piston 48 down and squeezing the spring 47. After the handwheel 2 is connected, the piston 48 will be misaligned with the hole of the oil pipe 42. At this time, the lubricating oil in the oil storage ring 43 will slowly pass through the gap between the piston 48 and the hole of the oil pipe 42 and slowly guide it into the oil pipe 42. Then the lubricating oil will be slowly guided to the connection between the valve stem 3 and the regulating valve body 1 and achieve lubrication. When the handwheel 2 and the valve stem 3 are disassembled, the pushing force on the push plate 46 will be removed. At this time, the spring 47 will drive the piston 48 and the push plate 46 to reset and block the oil pipe 42 again.

[0022] The docking mechanism 5 includes a sliding plate 51. An inner groove 21 is formed on the handwheel 2, and the sliding plate 51 is slidably inserted into the inner groove 21. A second spring 52 is fixedly installed on one side of the sliding plate 51, and the end of the second spring 52 is fixedly connected to the inner wall of the inner groove 21. A plug rod 53 is fixedly installed on the other side of the sliding plate 51. A plug hole 31 is formed at the top of the valve stem 3, and the plug rod 53 can slide through the handwheel 2 and slide into the plug hole 31. A push post 54 is fixedly connected to the sliding plate 51, and the push post 54 is slidably inserted into the handwheel 2. The upper end of the handwheel 2 has a through-hole that connects to the inner groove 21. The push groove 22 is connected to the valve stem 3, and the push column 54 is slidably inserted into the push groove 22. The cooperation between the push column 54 and the push groove 22 facilitates the movement and adjustment of the slide plate 51. The docking mechanism 5 also includes a locking rod 55, which is fixedly installed on the upper end of the valve stem 3 and is arranged in an array. The locking rod 55 can be slidably inserted into the handwheel 2. The inner wall of the handwheel 2 is provided with an array of locking grooves 23, and the locking rod 55 can be slidably inserted into the locking grooves 23. The cooperation between the locking rod 55 and the locking grooves 23 effectively improves the locking stability between the valve stem 3 and the handwheel 2.

[0023] By adopting the above technical solution, when the regulating valve body 1 is installed and put into use, if it is necessary to operate the regulating valve body 1, the user needs to push the push column 54 to move, which can drive the slide plate 51 to move, and then drive the insert rod 53 to move and squeeze the spring 2 52. When the push column 54 is completely moved from one end of the push groove 22 to the other end, stop pushing the push column 54 and put the handwheel 2 on the top of the valve stem 3 until the locking rod 55 is inserted into the inner cavity of the corresponding locking groove 23 and moves to the top of the inner cavity of the corresponding locking groove 23. Then release the push column 54. At this time, the spring 2 52 will drive the insert rod 53 to reset, so that the insert rod 53 can be inserted into the insertion hole 31. Thus, the handwheel 2 and the valve stem 3 are conveniently and stably connected. Then, the valve stem 3 can be rotated by operating the handwheel 2. After the regulating valve body 1 is used, the handwheel 2 can be easily removed by reversing the above steps.

[0024] Working principle: When the regulating valve body 1 is installed and put into use, if it is necessary to operate the regulating valve body 1, the user needs to push the push column 54 to move, which can drive the slide plate 51 to move, and then drive the insert rod 53 to move and squeeze the spring 2 52. When the push column 54 is completely moved from one end of the push groove 22 to the other end, stop pushing the push column 54 and put the handwheel 2 on the top of the valve stem 3 until the locking rod 55 is inserted into the inner cavity of the corresponding locking groove 23 and moves to the top of the inner cavity of the corresponding locking groove 23. Then release the push column 54. At this time, the spring 2 52 will drive the insert rod 53 to reset, so that the insert rod 53 can be inserted into the insertion hole 31. Thus, the handwheel 2 and the valve stem 3 are conveniently and stably connected. Then, the valve stem 3 can be rotated by operating the handwheel 2. After the regulating valve body 1 is used, the handwheel 2 can be easily removed by reversing the above steps.

[0025] During this period, when the handwheel 2 is connected to the valve stem 3, the push plate 46 will be pushed down synchronously, thereby pushing the push rod 45 and the piston 48 down and squeezing the spring 47. After the handwheel 2 is connected, the piston 48 will be misaligned with the hole of the oil pipe 42. At this time, the lubricating oil in the oil reservoir ring 43 will slowly pass through the gap between the piston 48 and the hole of the oil pipe 42 and slowly guide it into the oil pipe 42. Then the lubricating oil will be slowly guided to the connection between the valve stem 3 and the regulating valve body 1 and achieve lubrication. When the handwheel 2 and the valve stem 3 are disassembled, the pushing force on the push plate 46 will be removed. At this time, the spring 47 will drive the piston 48 and the push plate 46 to reset and block the oil pipe 42 again.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
