[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic automation components used to control fluids. They are actuators and are not limited to hydraulics and pneumatics. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium.

[0003] After searching, the utility model patent with patent authorization announcement number CN221647639U discloses a flow-adjustable solenoid valve, including: a tube body, which is connected to the pipeline, a valve core is slidably provided on the tube body, a driving member is fixed on the tube body to drive the valve core to slide, and the driving member drives the valve core to open and close the interior of the tube body; a control member is arranged on the top of the valve core, the control member cooperates with the tube body, and the control member limits the opening and closing degree of the valve core.

[0004] However, the above-mentioned solenoid valve still has some shortcomings in actual use. The most obvious one is that when the threaded sleeve is turned to control the valve core body to rise to the extreme position, the operator can only operate it through the openings on both sides of the driving member. Moreover, due to the obstruction of the driving member, there will be great difficulty in operation, which is too inconvenient in actual operation.

[0005] Therefore, it is necessary to invent a flow-adjustable solenoid valve to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a flow-adjustable solenoid valve, which can more conveniently rotate the threaded tube, thereby avoiding the inconvenience of operation caused by the obstruction of the protective shell, reducing the difficulty of operation and making actual use more convenient, so as to solve the problem proposed in the above background technology that when the threaded sleeve is turned to control the valve core body to rise to the extreme position, the operator can only operate through the openings on both sides of the driving member, and due to the obstruction of the driving member, there will be great difficulty in operation, which is too inconvenient in actual operation.

[0007] According to one aspect of the present disclosure, the following technical solution is provided: a flow-adjustable solenoid valve, comprising:

[0008] A solenoid valve body, the solenoid valve body is used to transport fluid;

[0009] A driving member, the driving member is used to drive the solenoid valve body to open and close; and

[0010] A height adjustment mechanism, comprising a threaded tube, a locking groove, a movable ring, an extension plate, a fixed cover, a second return spring, and a trapezoidal block;

[0011] The threaded pipe is threadedly connected to the inner side of the top end of the valve housing, and a plurality of locking grooves are provided. The plurality of locking grooves are evenly opened on the top outside the threaded pipe. The movable ring is rotatably sleeved on the top outside the threaded pipe through a bearing. The extension plate is fixedly provided on the outside of the movable ring, and the fixed cover is fixedly provided on the top of the extension plate. The second return spring is fixedly connected between the inner wall of the fixed cover and the trapezoidal block. The trapezoidal block is slidably provided on the inner side of the fixed cover and extends to the inner side of the adjacent locking groove.

[0012] According to at least one embodiment of the flow-adjustable solenoid valve disclosed herein, the solenoid valve body includes a tube body and a valve housing, and the valve housing is fixedly nested on the top of the tube body.

[0013] According to at least one embodiment of the flow-adjustable solenoid valve disclosed herein, the solenoid valve body further includes a valve core, a magnetic valve stem and a first return spring. The valve core is located inside the tube body and is slidably arranged on the inner side of the valve shell along the vertical direction. The magnetic valve stem is fixedly arranged on the top of the valve core and is slidably arranged on the inner side of the threaded tube and extends to the inside of the driving member. The first return spring is sleeved on the outer side of the magnetic valve stem and is located between the valve core and the threaded tube.

[0014] According to at least one embodiment of the flow-adjustable solenoid valve disclosed herein, the driving member includes a protective shell and an electromagnetic coil. The shell is fixedly disposed on the top of the valve housing, and the electromagnetic coil is located outside the magnetic valve stem and fixedly disposed inside the shell.

[0016] The technical effects and advantages of this utility model are:

[0017] The utility model is provided with a height adjustment mechanism, so that when the height of the threaded pipe needs to be adjusted, the swivel is manually rotated counterclockwise. When the swivel rotates, the movable ring is driven to rotate synchronously through the column and the extension plate, and the movable ring drives the trapezoidal clamping block to rotate through the fixed cover. When the trapezoidal clamping block rotates, the threaded pipe is driven to rotate through the locking groove. Since the threaded pipe is threadedly connected to the valve housing, the threaded pipe moves downward during rotation. When the protective shell blocks the extension plate and makes it unable to continue to rotate, the swivel is rotated clockwise. At this time, the fixed cover drives the trapezoidal clamping block to rotate clockwise. During this process, the inner wall of the locking groove pushes the inclined surface of the end of the trapezoidal clamping block, thereby causing the trapezoidal clamping block to compress the second return spring and disengage from the inner side of the locking groove until the extension plate is reset. Then, the counterclockwise and clockwise rotations are repeated until the adjustment is completed. Compared with existing similar products, the utility model can more conveniently rotate the threaded pipe, thereby avoiding the inconvenience of operation caused by the obstruction of the protective shell, reducing the difficulty of operation and being more convenient in actual use.

[0028] Figure 2 1 is a structural schematic diagram of a solenoid valve body 1 of a flow-adjustable solenoid valve according to an embodiment of the present disclosure.

[0029] Figure 3 3 is a structural schematic diagram of a height adjustment mechanism 3 of a flow-adjustable solenoid valve according to an embodiment of the present disclosure.

[0030] like Figure 1-Figure 3 As shown, the flow-adjustable solenoid valve disclosed herein may include: a solenoid valve body 1 , a driving member 2 , a height adjustment mechanism 3 and other components.

[0031] like Figure 2 As shown, in the present disclosure, the solenoid valve body 1 includes a tube body 11, a valve shell 12, a valve core 13, a magnetic valve stem 14 and a first return spring 15, wherein the valve shell 12 is fixedly nested on the top of the tube body 11, the valve core 13 is located inside the tube body 11 and is slidably arranged on the inner side of the valve shell 12 along the vertical direction, the magnetic valve stem 14 is fixedly arranged on the top of the valve core 13 and is slidably arranged on the inner side of the threaded tube 31, and extends to the inside of the driving member 2, and the first return spring 15 is sleeved on the outside of the magnetic valve stem 14 and is located between the valve core 13 and the threaded tube 31.

[0032] It should also be noted that the driving member 2 includes a protective shell and an electromagnetic coil. The shell is fixedly arranged on the top of the valve housing 12, and the electromagnetic coil is located outside the magnetic valve stem 14 and fixedly arranged inside the shell.

[0033] As a result, the electromagnetic coil generates magnetism after being energized, thereby driving the magnetic valve stem 14 to move upward on the inside of the threaded tube 31. During the upward movement of the magnetic valve stem 14, the first return spring 15 is compressed, and at the same time, the valve core 13 is driven to move upward on the inside of the tube body 11. As the valve core 13 continues to move upward, the space inside the tube body 11 for fluid to pass through continues to increase. When the magnetism of the electromagnetic coil increases, the valve core 13 rises, and when the magnetism of the electromagnetic coil weakens, the valve core 13 drops, thereby completing the flow regulation operation.

[0034] like Figure 3 As shown, in a preferred embodiment, the height adjustment mechanism 3 includes a threaded tube 31, a locking groove 32, a movable ring 33, an extension plate 34, a fixed cover 35, a second return spring 36, a trapezoidal block 37, a column 38 and a swivel 39, wherein the threaded tube 31 is threadedly connected to the inner side of the top end of the valve housing 12, a plurality of locking grooves 32 are provided, and a plurality of locking grooves 32 are evenly opened at the outer top of the threaded tube 31, the movable ring 33 is rotatably sleeved on the outer top of the threaded tube 31 through a bearing, the extension plate 34 is fixedly provided on the outer side of the movable ring 33, the fixed cover 35 is fixedly provided on the top of the extension plate 34, the second return spring 36 is fixedly connected between the inner wall of the fixed cover 35 and the trapezoidal block 37, the trapezoidal block 37 is slidably provided on the inner side of the fixed cover 35 and extends to the inner side of the adjacent locking groove 32, the column 38 is fixedly provided on the top of the extension plate 34, and the swivel 39 is fixedly provided on the top of the column 38.

[0035] Therefore, when the height of the threaded tube 31 needs to be adjusted, the swivel ring 39 is manually rotated counterclockwise. When the swivel ring 39 rotates, the movable ring 33 is driven to rotate synchronously through the column 38 and the extension plate 34. The movable ring 33 drives the trapezoidal block 37 to rotate through the fixed cover 35. When the trapezoidal block 37 rotates, the threaded tube 31 is driven to rotate through the locking groove 32. Since the threaded tube 31 is threadedly connected to the valve housing 12, the threaded tube 31 moves downward when it rotates. When the protective shell blocks the extension plate 34 so that the extension plate 34 cannot continue to rotate, the swivel ring 39 is rotated clockwise. At this time, the fixed cover 35 drives the trapezoidal block 37 to rotate clockwise. During this process, the inner wall of the locking groove 32 pushes the inclined surface of the end of the trapezoidal block 37, thereby causing the trapezoidal block 37 to compress the second return spring 36 and escape from the inner side of the locking groove 32 until the extension plate 34 is reset. Then, the counterclockwise and clockwise rotations are repeated until the adjustment is completed. Compared with existing similar products, the threaded tube 31 can be rotated more conveniently, thereby avoiding the inconvenience of operation caused by the obstruction of the protective shell, reducing the difficulty of operation and making actual use more convenient.

[0036] It should also be noted that the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0037] Those skilled in the art will appreciate that the above embodiments are merely intended to clearly illustrate the present disclosure and are not intended to limit the scope of the present disclosure. Other changes or modifications may be made based on the above disclosure, and such changes or modifications are still within the scope of the present disclosure.
