Description

Technical Field

[0001] This utility model relates to the field of valves, and more particularly to valves with adjustable length. Background Technology

[0002] A valve is a device used to control the flow of fluid in a pipeline. Cutting off the flow of fluid in a pipeline is the main function of various pipeline valves.

[0003] Existing valves lack the function of adjusting the length of the operating rod. In practical applications, the installation position of valves may vary, with some being deep and some shallow, and the distance from the operator may also vary. For example, in some industrial sites with complex pipeline layouts, or inside equipment with narrow spaces, if the length of the operating rod is fixed, it may be difficult for the operator to reach the valve to operate it, which increases the difficulty and danger of operation and reduces work efficiency.

[0004] Therefore, to address the issue that existing valves lack the function of adjusting the length of the operating rod, and that in some confined spaces, a fixed operating rod length may make it difficult for operators to reach the valve, increasing the difficulty and danger of operation and reducing work efficiency, an adjustable length valve can be designed. This can be achieved by installing a motor that drives a lead screw to rotate. The rotation of the lead screw, through a limit sleeve, restricts the rotation of the telescopic cylinder, allowing it to move up and down. This movement of the telescopic cylinder, in turn, moves a knob up and down, which in turn controls the valve's opening and closing, thus achieving the purpose of adjusting the length of the valve's control rod. Utility Model Content

[0005] To overcome the problem that existing valves lack the function of adjusting the length of the operating rod, in some confined spaces, if the length of the operating rod is fixed, it may be difficult for operators to reach the valve to operate, which increases the difficulty and danger of operation and reduces work efficiency.

[0006] The technical solution of this utility model is as follows: an adjustable valve, including a valve body; and also including a support base, a limiting sleeve, a motor, a lead screw, a telescopic cylinder and a knob. The upper surface of the valve body is provided with a support base, the upper surface of the support base is installed with a limiting sleeve, the lower surface of the limiting sleeve is provided with a motor, the output end of the motor passes through the lower surface of the limiting sleeve and is connected to a lead screw, the outer surface of the lead screw is threadedly connected to a telescopic cylinder, and the upper surface of the telescopic cylinder is provided with a knob.

[0007] Preferably, by setting up a motor, the motor drives a lead screw to rotate. When the lead screw rotates, it restricts the rotation of the telescopic cylinder through a limit sleeve, thereby driving the telescopic cylinder to move up and down. When the telescopic cylinder moves, it drives the knob to move up and down. By rotating the knob, the valve body can be opened and closed, thereby achieving the purpose of adjusting the length of the valve body control rod. This solves the problem that existing valves lack the function of adjusting the length of the operating rod. In practical applications, the installation position of the valve may vary, with different depths and different distances from the operator. For example, in some industrial sites with complex pipeline layouts, or inside equipment with narrow spaces, if the length of the operating rod is fixed, it may be difficult for the operator to reach the valve to operate, increasing the difficulty and danger of operation and reducing work efficiency.

[0008] Preferably, the outer surface of the knob is provided with a turntable, and a crank handle is rotatably connected to the outer side of the upper surface of the turntable.

[0009] Preferably, reflectors are provided on both the front and rear sides of the valve body. A movable frame is installed on the side of the two reflectors away from the valve body. A lead screw is rotatably connected to the inner right surface of the movable frame. The left surface of the lead screw is rotatably connected to the inner left surface of the movable frame. A sliding mounting block is threaded through the outer surface of the lead screw. A brush plate is provided on the lower surface of the sliding mounting block.

[0010] Preferably, a second motor is provided on the upper side of the right surface of the movable frame, and the output end of the second motor passes through the right surface of the movable frame and is connected to the right surface of the second lead screw.

[0011] Preferably, a limit rod is provided on the inner right surface of the movable frame, and a sliding mounting block two is slidably connected through the outer surface of the limit rod. The upper surface of the sliding mounting block two is connected to the lower surface of the brush plate.

[0012] Preferably, both ports of the valve body are provided with flanges, and bolts are connected to the threaded holes of the flanges.

[0013] Preferably, both flanges have an internal mounting frame, and a filter screen is installed inside the mounting frame.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a motor, motor one drives screw one to rotate. When screw one rotates, it restricts the rotation of the telescopic cylinder through a limit sleeve, thereby driving the telescopic cylinder to move up and down. When the telescopic cylinder moves, it drives the knob to move up and down. By rotating the knob, the valve body can be opened and closed, thereby adjusting the length of the valve body control rod. This solves the problem that existing valves lack the function of adjusting the length of the operating rod. In practical applications, the installation position of valves may vary, with different depths and different distances from the operator. For example, in some industrial sites with complex pipeline layouts or in equipment with narrow spaces, if the length of the operating rod is fixed, it may be difficult for the operator to reach the valve to operate, increasing the difficulty and danger of operation and reducing work efficiency.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of an adjustable valve, including a valve body 1; it also includes a support base 2, a limiting sleeve 3, a motor 4, a lead screw 5, a telescopic cylinder 6, and a knob 7. The support base 2 is provided on the upper surface of the valve body 1, and the limiting sleeve 3 is installed on the upper surface of the support base 2. The motor 4 is provided on the lower surface of the limiting sleeve 3, and the output end of the motor 4 passes through the lower surface of the limiting sleeve 3 and is connected to the lead screw 5. The outer surface of the lead screw 5 is threadedly connected to the telescopic cylinder 6, and the knob 7 is provided on the upper surface of the telescopic cylinder 6. By providing the motor 4, when the motor 4 is running, it drives the lead screw 5 to rotate. When the lead screw 5 rotates, it restricts the rotation of the telescopic cylinder 6 through the limiting sleeve 3, thereby driving the telescopic cylinder 6 to move up and down. When the telescopic cylinder 6 moves, it drives the knob 7 to move up and down. By rotating the knob 7, the valve body 1 can be opened and closed, thereby achieving the purpose of adjusting the length of the control rod of the valve body 1.

[0023] Please see Figures 2-4 In this embodiment, a turntable 8 is provided on the outer surface of the knob 7, and a crank handle 9 is rotatably connected to the outer side of the upper surface of the turntable 8. By providing the turntable 8, the torque applied to the knob 7 is increased, making it easier for the operator to turn the knob 7. By providing the crank handle 9, the operator has a comfortable grip point, thereby achieving the purpose of turning the knob 7 with less effort. Reflectors 10 are provided on both the front and rear sides of the valve body 1. A movable frame 11 is installed on the side of the two reflectors 10 away from the valve body 1. A lead screw 13 is rotatably connected to the inner right surface of the movable frame 11. The left surface of the lead screw 13 is rotatably connected to the inner left surface of the movable frame 11. A sliding mounting block 14 is threadedly connected to the outer surface of the lead screw 13. The lower part of the sliding mounting block 14... A brush plate 15 is provided on the surface. A reflector 10 is provided to remind the operator of the position of the valve body 1 and avoid collisions during operation. A lead screw 13 is provided. When the lead screw 13 rotates, it restricts the rotation of the sliding mounting block 14 through the moving frame 11, thereby driving the sliding mounting block 14 to move. When the sliding mounting block 14 moves, it drives the brush plate 15 to move, thereby achieving the purpose of cleaning the reflector 10. A motor 12 is provided on the upper right surface of the moving frame 11. The output end of the motor 12 passes through the right surface of the moving frame 11 and is connected to the right surface of the lead screw 13. By providing the motor 12, the operation of the motor 12 drives the lead screw 13 to rotate, thereby achieving the purpose of automated cleaning.

[0024] Please see Figures 1-3In this embodiment, a limiting rod 16 is provided on the inner right surface of the movable frame 11. A sliding mounting block 17 is slidably connected through the outer surface of the limiting rod 16. The upper surface of the sliding mounting block 17 is connected to the lower surface of the brush plate 15. By providing the sliding mounting block 17, the brush plate 15 moves, causing the sliding mounting block 17 to move. The movement of the sliding mounting block 17 is restricted by the limiting rod 16, thereby indirectly strengthening the rotation restriction of the sliding mounting block 14 through the brush plate 15, thus achieving the purpose of making the movement of the sliding mounting block 14 more stable. Flanges 18 are provided at both ports of the valve body 1. Bolts 19 are connected to the threaded holes of the flanges 18. By setting up the flanges 18, the valve body 1 can be easily separated from or connected to the pipeline by simply loosening the bolts 19 on the flanges 18, which greatly improves the efficiency of installation and maintenance, thereby facilitating the installation and disassembly by operators. The two flanges 18 are equipped with mounting frames 20 inside, and filter screens 21 are installed inside the mounting frames 20. By setting up the filter screens 21, large particulate impurities in the fluid, such as mud, rust, floating objects, etc., can be intercepted, preventing these impurities from entering the valve body 1 and avoiding blockage of the valve body 1, which would affect the normal operation of the internal components of the valve body 1.

[0025] During operation, the turntable 8 increases the torque applied to the knob 7, making it easier for the operator to turn it. The crank handle 9 provides a comfortable grip, further reducing the effort required to turn the knob. The reflector 10 alerts the operator to the position of the valve body 1, preventing collisions during operation. The second lead screw 13, when rotating, restricts the rotation of the sliding mounting block 14 via the moving frame 11, causing the sliding mounting block 14 to move. This movement of the sliding mounting block 14 then moves the brush plate 15, cleaning the reflector 10. Finally, the second motor 12, which drives the second lead screw 13, achieves automated cleaning. By setting a sliding mounting block 17, the sliding mounting block 17 moves when the brush plate 15 moves. The sliding mounting block 17 is restricted by the limit rod 16 when it moves, thereby indirectly strengthening the rotation restriction of the sliding mounting block 14 through the brush plate 15, so as to make the sliding mounting block 14 more stable when it moves. By setting a flange 18, the valve body 1 can be easily separated or connected to the pipeline by simply loosening the bolts 19 on the flange 18, which greatly improves the efficiency of installation and maintenance, so as to facilitate the installation and disassembly by the operator. By setting a filter screen 21, large particulate impurities in the fluid, such as mud, rust, floating objects, etc., can be intercepted to prevent these impurities from entering the valve body 1 and avoiding blockage of the valve body 1, which would affect the normal operation of the internal components of the valve body 1.

[0026] Through the above steps, by setting up motor 4, motor 4 drives lead screw 5 to rotate when it runs. When lead screw 5 rotates, it restricts the rotation of telescopic cylinder 6 through limit sleeve 3, thereby driving telescopic cylinder 6 to move up and down. When telescopic cylinder 6 moves, it drives knob 7 to move up and down. By rotating knob 7, the valve body 1 can be opened and closed, thereby achieving the purpose of adjusting the length of valve body 1 control rod. This solves the problem that existing valves lack the function of adjusting the length of the operating rod. In actual applications, the installation position of valves may vary, with different depths and different distances from the operator. For example, in some industrial sites with complex pipeline layouts, or inside equipment with narrow spaces, if the length of the operating rod is fixed, it may be difficult for the operator to reach the valve to operate, increasing the difficulty and danger of operation and reducing work efficiency.
