[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein can be arranged and designed in a variety of different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0024] The following combination Figure 1-5 The specific embodiment of the utility model is described. A high-precision adjustable numerical control flow valve includes a valve body 1, a support rod 2 is provided on the valve body 1, a support plate 4 is provided on the support rod 2, a valve shaft 11 is movably provided on the support plate 4, a valve disc 15 is provided at one end of the valve shaft 11, a packing 16 is provided on the valve body 1, an adjustment component is provided on the support plate 4, an indicator component is provided on the support rod 2, the adjustment component includes a transmission box 5 and a motor 18, the transmission box 5 is mounted on the support plate 4, a connecting rod 10 is movably provided on the transmission box 5, the The motor 18 is installed on the connecting rod 10, and the driving end of the motor 18 is connected to one end of the valve shaft 11. A transmission assembly is provided in the transmission box 5, and a pair of support rods 2 are provided and installed on the valve body 1. One end of the valve disc 15 enters the valve body 1. The motor 18 can drive the valve shaft 11 to rotate and move, and then the valve disc 15 moves with the valve shaft 11. The size of the flow rate passing through the valve body 1 can be controlled by the height of the valve disc 15. The transmission box 5 and the connecting rod 10 are provided with a pair, and a pair of connecting rods 10 support the motor 18. The packing 16 can make the valve shaft 11 be placed stably on the valve body 1.

[0025] Advantageously, the transmission box 5 is provided with a groove near the side wall of the support plate 4. Since a fixing nut is provided on the upper wall of the support plate 4, the groove can prevent the transmission box 5 from interfering with the nut, thereby facilitating the fixation of the transmission box 5 on the support plate 4.

[0026] Beneficially, the transmission assembly includes a sliding plate 7, a sliding rail 6 and a spring 8. The sliding rail 6 is arranged on the inner wall of the transmission box 5, and the sliding plate 7 is slidably arranged on the sliding rail 6. The spring 8 is installed on the inner wall of the transmission box 5 and the other end of the spring 8 is connected to the sliding plate 7. One end of the connecting rod 10 is installed on the side wall of the sliding plate 7 away from the spring 8 and the other end of the connecting rod 10 passes through the side wall of the transmission box 5. The spring 8 can support the sliding plate 7. When the motor 18 drives the valve shaft 11 to rotate, the motor 18 will move toward the valve body 1. At this time, the connecting rod 10 drives the sliding plate 7 to slide on the sliding rail 6, and the spring 8 is compressed, so that the distance between the valve disc 15 and the valve body 1 can be adjusted to facilitate flow control.

[0027] Advantageously, a baffle 9 is provided in the transmission box 5. When the sliding plate 7 contacts the baffle 9, it means that the valve disc 15 is released from the valve body 1. At this time, the flow channel is blocked and the fluid cannot pass through the flow channel, preventing the valve shaft 11 from driving the valve disc 15 to move excessively and causing damage to itself.

[0028] Advantageously, a rotating assembly is further included, which includes a thread 12 and a notch 17 . The thread 12 is provided on the valve shaft 11 , and the notch 17 is provided on the support plate 4 . The valve shaft 11 is easily driven through the thread 12 in the notch 17 on the support plate 4 .

[0029] Advantageously, the notch 17 is adapted to the thread 12 , and the adapted notch 17 can make the thread 12 on the valve shaft 11 more stable during transmission.

[0030] Advantageously, the indicating assembly includes a scale line 3 and a movable frame 13, the scale line 3 being arranged on the support rod 2, the movable frame 13 being movably arranged on the valve shaft 11, the movable frame 13 being provided with an indicating block 14, a pair of scale lines 3 being provided, respectively arranged on a pair of support rods 2, the movable frame 13 and the valve shaft 11 being connected via bearings (not shown in the figure), the valve shaft 11 being rotated and moved, while the movable frame 13 only moves on a pair of support rods 2 and does not rotate, the indicating block 14 on the movable frame 13 corresponds to the scale line 3, which is convenient for checking the moving distance, and further facilitates high-precision control of the fluid flow rate.

[0031] Advantageously, the connecting rod 10 and the motor 18 are fixedly connected by bolts, and the motor 18 is easily installed and removed from the connecting rod 10 by being fixedly connected by bolts.

[0032] Working principle of this utility model:

[0033] First, the motor 18 is connected to the CNC control equipment. When the flow through the valve body 1 needs to be adjusted, the motor 18 is driven. The motor 18 drives the valve shaft 11 to rotate. The thread 12 on the valve shaft 11 is adapted to the slot 17 on the support plate 4. The valve shaft 11 rotates and moves at the same time, and the valve disc 15 moves following the valve shaft 11. The movable frame 13 can drive the indicator block 14 to move on the support rod 2 under the action of the valve shaft 11. The height of the valve disc 15 movement can be controlled by the scale indicated by the indicator block 14, which facilitates high-precision control of the flow through the valve body 1. When the valve needs to be closed, the connecting rod 10 slides on the slide rail 6 through the sliding plate 7 under the action of the motor 18. When the sliding plate 7 abuts against the baffle 9, the sliding plate 7 cannot move. At this time, it means that the valve disc 15 abuts against the valve body 1, and the fluid cannot pass through the valve body 1. The baffle 9 prevents the valve disc 15 from moving excessively.

[0034] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0035] The above content is merely an example and explanation of the structure of the present utility model. Technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the scope of protection of the present utility model.
