Description

Technical Field

[0001] The utility model relates to the technical field of flow regulating valves, in particular to a multifunctional electric flow regulating valve. Background Art

[0002] The multifunctional electric flow control valve is a control valve that integrates flow control, electric control and automation functions. It is usually composed of an electric actuator and a control valve. Through the control of the electric actuator, the flow of the fluid medium can be regulated.

[0003] In conjunction with publication number CN217633927U, publication date 2022-10-21, an electric dynamic flow control valve is disclosed.

[0004] In the prior art including the above patents, when the pressure of the medium inlet cavity increases, the medium will overcome the elastic force of the disc spring to push the valve core upward, the flow tube will move upward synchronously, the opening between the flow slot and the opening will increase, and the flow rate will increase at the same time. At this time, the pressure of the medium inlet cavity and the medium outlet cavity will slowly balance. After the pressure is balanced, the height of the valve core remains fixed, the flow protection is stable, and the function of synchronously fine-tuning the flow of the regulating valve while the inlet flow increases is realized. The above technology controls the flow rate by driving the flow slot up and down through the pressure of the medium. However, in application scenarios such as urban sewers, the medium often contains impurities such as mud, fallen leaves, etc. Since the flow slot is a narrow structure at the top and wide at the bottom, it is easy to cause the flow slot to be blocked with the inner wall of the valve body, thereby affecting the automatic control effect of the flow rate.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1-3 As shown, a multifunctional electric flow regulating valve comprises a valve body 1 and a medium inlet 2 and a medium outlet 3 arranged thereon, wherein the medium inlet 2 and the medium outlet 3 are separated by a partition fixedly arranged in the valve body 1;

[0025] A water inlet 9 is provided on the partition plate and is used to connect the medium inlet 2 and the medium outlet 3. The water inlet 9 is a hollow cone structure extending toward the sewage outlet 4. The angle between the side wall of the water inlet 9 and the partition plate is 120°.

[0026] The sewage outlet 4 is provided on the valve body 1 and arranged coaxially with the water inlet 9, and the included angle between the sewage outlet 4 and the inner wall of the valve body 1 is 45°;

[0027] A sleeve 6 is provided on the partition plate, a plurality of flow outlets 61 are provided on the sleeve 6, and a valve core 7 for blocking the water inlet 9 is slidably provided in the sleeve 6;

[0028] A filter screen 63 is disposed in the outflow port 61 .

[0029] Specifically, the sewage outlet 4 is closed by a sealing cover 8 , and a hand wheel is fixedly provided on the sealing cover 8 , and a rubber sealing ring is provided at the connection between the valve core 7 and the sleeve 6 .

[0030] Furthermore, after the medium enters the valve body 1 through the medium inlet 2, the electric actuator 5 is started to drive the valve core 7 to move up and down, and the flow at the water inlet 9 is controlled by the change of the gap between the valve core 7 and the water inlet 9. After passing through the water inlet 9, the medium enters the sleeve 6. Since the angle between the water inlet 9 and the partition is 120°, the medium is diverted by the water inlet 9 during the upward flow. The medium diverted to the outer wall of the water inlet 9 generates a small vortex under the restriction of the partition, and the impurities contained are blocked outside the water inlet 9. The remaining impurities such as mud and sand in the sleeve 6 are intercepted by the inner wall of the filter screen 63, and the screened medium enters the medium outlet 3 through the outflow port 61. To ensure the cleanliness of the medium, the valve core 7 scrapes the inner wall of the filter screen 63 during the up and down movement, so that the mud and sand are peeled off. Under the combined action of gravity and the driving force generated by the downward movement of the valve core 7, the mud and sand are deposited on the water inlet 9, so that the mud and sand roll down along the inner wall of the water inlet 9 and flow into the sewage outlet 4 when the valve core 7 leaves the water inlet 9. Since the angle between the sewage outlet 4 and the inner wall of the valve body 1 is 45°, the deposited mud and sand gather in the sewage outlet 4. When cleaning is required, the medium inlet 2 no longer flows into the medium. The operator can open the sealing cover 8 by turning the hand wheel to allow the residual medium in the valve body 1 to flush the mud and sand, and remove impurities such as mud and sand.

[0031] In the above technology, the medium enters the sleeve 6 after passing through the water inlet 9. Since the angle between the water inlet 9 and the partition is 120°, the medium is diverted by the water inlet 9 during the upward flow, and some impurities are precipitated. The remaining impurities are then intercepted on the inner wall of the filter 63, so that the medium is clean. At the same time, the valve core 7 scrapes the inner wall of the filter 63 during the up and down movement, so that the mud and sand are peeled off to avoid blockage caused by impurities such as mud and sand. When cleaning is required, the operator can open the sealing cover 8 by turning the hand wheel, and use the remaining medium in the valve body 1 to flush the mud and sand. The operation is relatively simple.

[0032] As an embodiment further provided by the present invention, a reflux chamber 10 communicating with the medium outlet 3 is provided inside the valve body 1 .

[0033] Specifically, when the water pressure at the medium outlet 3 is high, after the valve core 7 blocks the water inlet 9, it will flow back into the reflux chamber 10. At this time, the medium will exert downward pressure on the valve core 7 after passing through the outflow port 61. In this process, the sediment attached to the filter screen 63 is driven to flow and settle above the valve core 7, thereby preventing the sediment from agglomerating on the filter screen 63 and causing blockage.

[0034] As another embodiment further provided by the present invention, the valve core 7 is arranged in a spindle-shaped structure.

[0035] Specifically, the spindle-shaped structure makes the contact surface between the valve core 7 and the medium V-shaped, reducing the impact of pressure on the valve core 7, while reducing the contact area between the valve core 7 and the sleeve 6, avoiding the formation of a closed space between the valve core 7 and the sleeve 6. When mud and sand settle on the top of the valve core 7, it will roll down along the inclined surface to avoid mud and sand accumulation.

[0036] As another embodiment further provided by the present invention, a plurality of guide grooves 71 are arranged in a circumferential array on the valve core 7 , and the ends of the guide grooves 71 are all provided with retention arc-shaped pieces 72 that abut against the filter screen 63 .

[0037] Specifically, when the silt settles above the valve core 7, it rolls down along the guide groove 71 and is finally retained on the retention arc piece 72, so that the silt accumulates in the gap between the valve core 7 and the water inlet 9. When the valve core 7 moves upward, the silt loses its obstruction and settles downward along the water inlet 9 under the action of gravity and flows into the sewage outlet 4. The retention arc piece 72 continuously scrapes the inner wall of the filter screen 63 during the movement of the valve core 7, and scrapes off the impurities attached to the filter screen 63.

[0038] As another embodiment further provided by the present invention, a paddle 62 is provided in the outlet 61 at an angle of 45°.

[0039] Specifically, the sleeve 6 is rotatably arranged inside the valve body 1. When the medium enters the reflux chamber 10 through the sleeve 6, it impacts the paddle 62. Since the paddle 62 is a curved arc blade, the medium pushes the paddle 62 to drive the sleeve 6 to rotate. During the rotation of the sleeve 6, impurities attached to the filter screen 63 are easier to peel off.

[0040] Working principle: After the medium enters the valve body 1 through the medium inlet 2, the electric actuator 5 is started to drive the valve core 7 to move up and down, and the flow at the water inlet 9 is controlled by the change of the gap between the valve core 7 and the water inlet 9. After passing through the water inlet 9, the medium enters the sleeve 6. Since the angle between the water inlet 9 and the partition is 120°, the medium is diverted by the water inlet 9 during the upward flow. The medium diverted to the outer wall of the water inlet 9 generates a small vortex under the restriction of the partition, and the impurities contained are blocked at the water inlet. 9, the remaining impurities such as mud and sand in the sleeve 6 are intercepted by the inner wall of the filter screen 63, and the screened medium enters the medium outlet 3 through the outflow port 61. In the process of the medium passing through the sleeve 6 and entering the reflux chamber 10, the paddle 62 is impacted. Since the paddle 62 is a curved arc blade inclined at 45 degrees, the medium pushes the paddle 62 to drive the sleeve 6 to rotate. During the rotation of the sleeve 6, the impurities attached to the filter screen 63 are easier to peel off; when the water pressure at the medium outlet 3 is high, when the valve core 7 seals the water inlet 9, the impurities attached to the filter screen 63 are more likely to be peeled off. After being blocked, it will flow back into the reflux chamber 10. At this time, the medium will generate downward pressure on the valve core 7 after passing through the outflow port 61. In this process, the silt attached to the filter screen 63 will flow and settle above the valve core 7, roll down along the guide groove 71, and finally stay on the retention arc sheet 72, so that the silt accumulates in the gap between the valve core 7 and the water inlet 9. When the valve core 7 moves upward, the silt loses its obstruction and settles down along the water inlet 9 under the action of gravity, and merges into the sewage outlet 4, and the retention arc sheet 72 is retained. During the movement of the valve core 7, the sheet 72 continuously scrapes the inner wall of the filter screen 63 to scrape off the impurities attached to the filter screen 63. Under the combined effect of gravity and the driving force generated by the downward movement of the valve core 7, since the angle between the sewage outlet 4 and the inner wall of the valve body 1 is 45°, the precipitated silt gathers in the sewage outlet 4. When cleaning is required, the medium inlet 2 no longer flows into the medium. The operator can open the sealing cover 8 by turning the hand wheel to allow the remaining medium in the valve body 1 to flush the silt and remove impurities such as silt.

[0041] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
