DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] As Figure 1 and Figure 2As shown in the figure, the utility model provides a technical solution: a flow regulating valve with a positioning function, which includes a valve body 1. On both sides of the outer wall of the valve body 1, a water inlet pipe 11 and a water outlet pipe 12 are installed. At the top of the valve body 1, a valve cover 2 is installed. From the top of the valve cover 2 to the inside of the valve body 1, an adjusting component 3 is arranged. The adjusting component 3 includes a threaded rod 31. A first threaded hole 21 is opened at the top of the valve cover 2. The threaded rod 31 is threadedly inserted into the first threaded hole 21. At the bottom of the threaded rod 31, a valve flap 32 is installed. At the top of the valve flap 32, a rotating ring 33 is installed, which makes it more convenient to operate the rotation of the threaded rod 31. The surface of the threaded rod 31 is equidistantly provided with positioning grooves 34. Through this structure, by rotating the rotating ring 33, the rotating ring 33 drives the threaded rod 31 to rotate in the first threaded hole 21, and the threaded rod 31 drives the valve flap 32 to rotate. Through threaded rotation, the threaded rod 31 drives the valve flap 32 to move up and down inside the valve body 1. In this way, the rotating ring 33 can adjust and control the water inflow, making the adjustment of the device's flow more simple and convenient.

[0022] As an implementation manner in this embodiment, as Figure 3 and Figure 4As shown in the figure, a positioning mechanism for positioning the adjustment assembly 3 is provided at the top end of the valve cover 2. The positioning mechanism includes a locking assembly 4 for restricting the rotation of the adjustment assembly 3 and a rotating assembly 5 for adjusting the rotation of the locking assembly 4. The locking assembly 4 and the rotating assembly 5 are arranged on one side of the top end of the valve cover 2 close to the threaded rod 31. The locking assembly 4 includes a support rod 41. The support rod 41 is installed at the top end of the valve cover 2 through the rotating assembly 5. A fixed rod 42 is fixedly installed at the top end of the support rod 41. A chute 43 is opened at one end of the fixed rod 42 close to the threaded rod 31. A spring 44 is arranged inside the chute 43. A positioning rod 45 is slidably installed at the opening of the chute 43, and the positioning rod 45 is inserted into the positioning groove 34. Two ends of the spring 44 are respectively connected with the inner wall of the chute 43 and the inner end of the positioning rod 45. After the positioning rod 45 is rotated and adjusted to correspond to the positioning groove 34 through the rotating assembly 5 in this structure, the positioning rod 45 can be pushed by the restoring force of the spring 44 to insert into the appropriate positioning groove 34 to position the threaded rod 31. In this way, the threaded rod 31 is not easily rotated due to external force factors, affecting the adjustment of the flow rate, making the control of the flow rate of this device more stable and greatly increasing the practicability of this device. A through hole 46 is opened at one end of the fixed rod 42 far from the threaded rod 31. A pull rod 47 is connected to the inner end of the positioning rod 45. A pull ring 48 is installed at one end of the pull rod 47 far from the positioning rod 45 through the through hole 46. In this structure, by pulling the pull ring 48, the pull ring 48 pulls the pull rod 47 to slide in the through hole 46 until the pull rod 47 pulls the positioning rod 45 out of the positioning groove 34 and moves into the chute 43 to compress the spring 44, so as to pull the positioning rod 45 out of the positioning groove 34 to unlock the positioning of the threaded rod 31. The operation is more convenient and simpler, greatly increasing the convenience of this device. Moreover, the pull ring 48 makes it more convenient to pull the pull rod 47. A clamping block 49 is connected to one side of the pull rod 47 close to the positioning rod 45. A groove 410 is opened on the inner wall of the through hole 46. The clamping block 49 passes through the groove 410 and is clamped on the side end of the fixed rod 42, so that by clamping the clamping block 49 on the side end of the fixed rod 42, the positioning rod 45 can be kept in the chute 43, making it more convenient to operate and rotate the threaded rod 31 again to adjust the flow rate.

[0023] It should be noted that there is a certain distance between the fixed rod 42 and the threaded rod 31. In this way, after the positioning rod 45 is retracted into the chute 43, the fixed rod 42 will not prevent the threaded rod 31 from rotating.

[0024] As an implementation method in this embodiment, such as Figure 3 and Figure 4As shown, the rotating assembly 5 includes a slide rail 51, which is fixedly connected to the top end of the valve cover 2. A sliding seat 52 is slidably sleeved on the surface of the slide rail 51. The bottom end of the support rod 41 is fixedly connected to one side of the top end of the sliding seat 52. A second threaded hole 53 is formed in the top end of the sliding seat 52. A fastening screw rod 54 is threadedly inserted into the second threaded hole 53. A handle 55 is installed at the top end of the fastening screw rod 54. With this structure, by pushing the sliding seat 52 to rotate along the slide rail 51, the sliding seat 52 drives the locking assembly 4 to rotate, so that the locking assembly 4 can be adjusted according to the orientation of the positioning groove 34. Then, rotate the handle 55. The handle 55 drives the fastening screw rod 54 to rotate in the second threaded hole 53. Through screw rotation, until the fastening screw rod 54 tightly abuts against the slide rail 51. In this way, the sliding seat 52 can be fixed by friction, so that the fixing rod 42 and the positioning rod 45 can be fixed, greatly increasing the stability of the device. A rubber pad 56 is glued to the bottom end of the fastening screw rod 54, so that the friction between the fastening screw rod 54 and the slide rail 51 can be increased when they abut against each other, thus fixing the sliding seat 52 more firmly.

[0025] Working principle: If it is necessary to adjust the water inflow of the device, just rotate the rotating ring 33. The rotating ring 33 drives the threaded rod 31 to rotate in the first threaded hole 21. The threaded rod 31 drives the valve flap 32 to rotate. Through screw rotation, the threaded rod 31 drives the valve flap 32 to move up and down inside the valve body 1. In this way, the rotating ring 33 can adjust and control the water inflow, making the adjustment and flow of the device simpler and more convenient. Then, push the sliding seat 52 to rotate along the slide rail 51. The sliding seat 52 drives the support rod 41 to rotate. The support rod 41 drives the fixing rod 42 to rotate. The fixing rod 42 drives the positioning rod 45 to rotate until the positioning rod 45 rotates to correspond to the positioning groove 34. At this time, rotate the handle 55. The handle 55 drives the fastening screw rod 54 to rotate in the second threaded hole 53. Through screw rotation, the fastening screw rod 54 drives the rubber pad 56 to move downward until the fastening screw rod 54 drives the rubber pad 56 to tightly abut against the slide rail 51. In this way, the sliding seat 52 can be fixed by friction, so that the fixing rod 42 and the positioning rod 45 can be fixed, greatly increasing the stability of the device. Finally, the positioning rod 45 can be pushed into the appropriate positioning groove 34 by the restoring force of the spring 44 to position the threaded rod 31. In this way, the threaded rod 31 is not easily rotated due to external factors, affecting the adjustment of the flow rate, making the flow rate control of the device more stable and greatly increasing the practicability of the device;

[0026] In addition, if the flow rate needs to be adjusted again, it is only necessary to pull the pull ring 48 first, and the pull ring 48 will pull the pull rod 47 to slide in the through hole 46 until the pull rod 47 pulls the positioning rod 45 out of the positioning groove 34 and moves it to the slide groove 43 to compress the spring 44. At this time, the pull rod 47 will also drive the block 49 to pass through the groove 410 and move to the outside of the fixed rod 42. Then rotate the pull ring 48, the pull ring 48 drives the pull rod 47 to rotate, and the pull rod 47 drives the block 49 to rotate, so that the block 49 is staggered with the groove 410, so that the block 49 can be stuck in the side end of the fixed rod 42, so that the positioning rod 45 remains in the slide groove 43, and then the rotating ring 33 can be rotated again to drive the threaded rod 31 to rotate, and the threaded rod 31 drives the valve disc 32 to move up and down to adjust the flow rate, thereby making it more convenient to unlock the threaded rod 31.

[0027] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
