Description

Technical Field

[0001] The present invention relates to the technical field of valves, and in particular to a valve with an anti-blocking and sewage discharge structure. Background Art

[0002] A valve is a mechanical device used to control the flow of water. It opens, closes, or regulates the flow of water to control the flow, pressure, or direction of the water. By adjusting the opening of the valve, the valve can accurately control the flow of water. In complex piping systems, valves can be used to divert or merge water to meet the needs of different pipelines. China's authorized patent announcement number CN213745126U discloses a civil valve for construction with an anti-blocking structure, comprising a valve body, a water inlet end, a filter end, a filter tube, a mounting end, a drive motor, a rotating shaft, a connecting shaft, a nut, a sealing cover, and a positioning end. The valve body comprises the water inlet end, the filter end, the mounting end, and the positioning end. The filter tube is movably mounted within the filter end. The drive motor is fixedly mounted on the mounting end, and a rotating shaft is fixedly connected to the output shaft of the drive motor. The end of the rotating shaft is fixedly connected to the connecting shaft, and a nut is threadedly mounted on the end of the connecting shaft. This civil valve for construction with an anti-blocking structure filters the water flowing into the valve body by providing a filter end on the water inlet end of the valve and installing a filter tube inside the filter end, thereby preventing impurities in the water flow from clogging and damaging components such as the valve core inside the valve, thereby increasing the service life of the valve. The above patent mentioned that the valve starts the drive motor to drive the filter tube on the rotating shaft to rotate, adjust the filtering surface of the filter tube, and improve the service life of the filter tube. However, when the filter tube is put into use, impurities in the water flow will still block the pores of the filter tube, and impurities will easily accumulate on the filter plate. The blockage will make it difficult for the water to pass through the filter tube normally, thereby reducing the filtering area and filtering efficiency, making it difficult for the water to pass smoothly through the valve. Therefore, we propose a valve with an anti-blocking sewage discharge structure. Summary of the Invention

[0027] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] See also Figures 1 to 3 As shown, a valve with an anti-blocking and sewage discharge structure includes a valve body 1, a filter plate 11 is provided at the water inlet of the valve body 1, and the filter plate 11 is fixedly connected to the sealing ring 12; a placement groove 13 for placing the filter plate 11 is provided at the water inlet of the valve body 1; a cleaning member 14 for removing impurities from the filter holes of the filter plate 11 is provided on one side of the filter plate 11; the valve body 1 is provided with a driving mechanism for providing cleaning power to the cleaning member 14; and a mounting mechanism for mounting the filter plate 11 to the valve body 1 is provided on the lower side of the filter plate 11.

[0029] Specifically, the sealing ring 12 is made of a deformable rubber material as an implementation element, and the sealing ring 12 is kept in an extruded state with the placement groove 13. The cleaning member 14 is kept in an extruded state with the filter plate 11, and the cleaning member 14 is a brush that does not damage the filter plate 11 as an implementation element.

[0030] Before the valve body 1 is put into use, the filter plate 11 is inserted into the seating groove 13. This allows the sealing ring 12 to press into contact with the seating groove 13. The sealing ring 12, made of a deformable rubber material, forms a seal between the filter plate 11 and the seating groove 13. After the filter plate 11 is secured to the valve body 1 via the mounting mechanism, it can filter impurities from the water.

[0031] At the same time, the driving mechanism drives the cleaning member 14 to rotate, and the cleaning member 14 maintains a squeeze state with the filter plate 11. The cleaning member 14 is made of a brush material that does not damage the filter plate 11. It can sweep away impurities accumulated on the outside of the filter plate 11, thereby maintaining the filter plate 11 unobstructed, preventing impurity accumulation from affecting the filtration performance, ensuring filtration efficiency and effect, and keeping the valve body 1 unobstructed, reducing water flow resistance.

[0032] When impurities need to be cleaned, the filter plate 11 is disassembled through the mounting mechanism, and the valve body 1 can discharge the impurities. At the same time, the filter plate 11 and the cleaning member 14 can be cleaned or replaced.

[0033] See also Figures 3 to 6 、 Figure 8 and Figure 9 As shown, the driving mechanism includes a power piece 2 and a bevel gear assembly 21; the power piece 2 is arranged on the valve body 1, and the power piece 2 is used to provide rotational power for the cleaning piece 14; the bevel gear assembly 21 can be rotatably arranged in the valve body 1, and the working end of the bevel gear assembly 21 is connected to the output end of the power piece 2, and the bevel gear assembly 21 is used to receive the rotational power of the output end of the power piece 2; the driving mechanism also includes a clamping assembly and a positioning assembly; the clamping assembly is arranged between the cleaning piece 14 and the bevel gear assembly 21, and the clamping assembly is used to transmit the rotational power of the bevel gear assembly 21 to the cleaning piece 14; the positioning assembly is arranged between the cleaning piece 14 and the filter plate 11, and the positioning assembly is used to assist the cleaning piece 14 to move vertically downward on the surface of the filter plate 11; the clamping assembly includes a clamping block 22 and a chuck 23; the clamping block 22 is fixedly connected to the working end of the bevel gear assembly 21; the chuck 23 can be rotatably connected to the filter plate 11, the chuck 23 is fixedly connected to one end of the cleaning piece 14, and the groove 24 of the chuck 23 is docked with the clamping block 22.

[0034] Specifically, the power member 2 uses a motor as an implementation element. The bevel gear assembly 21 is composed of two bevel gears meshing with each other. The clamping block 22 is engaged with the groove 24.

[0035] When the filter plate 11 is inserted into the placement groove 13, the filter plate 11 drives the chuck 23 to approach the block 22. The cleaning member 14 is kept in a vertical position on the outside of the filter plate 11 by the positioning assembly, ensuring that the groove 24 opens upward so that the groove 24 and the block 22 can dock. After the filter plate 11 is fixed in the placement groove 13 by the installation mechanism, the power member 2 is started, and the output end of the power member 2 drives the rotating end on one side of the bevel gear assembly 21 to rotate. Since the bevel gear assembly 21 is composed of two mutually meshing bevel gears, the power member 2 can drive the block 22 to rotate through the bevel gear assembly 21, and the block 22 is engaged with the groove 24, so that the block 22 can drive the chuck 23 to rotate through the groove 24, so that the chuck 23 drives the cleaning member 14 to rotate synchronously.

[0036] At this time, the cleaning member 14 can sweep away the impurities accumulated on the filter plate 11 to prevent the impurities from clogging the filter holes of the filter plate 11 , thereby ensuring efficient operation of the filter plate 11 and ensuring that water flows through the filter plate 11 normally.

[0037] See also Figure 5 and Figure 8 As shown, the positioning assembly includes a counterweight block 25, a first magnetic block 26 and a second magnetic block 27; the counterweight block 25 is fixedly connected to the end of the cleaning member 14 away from the chuck 23; the first magnetic block 26 is embedded in the outer side of the counterweight block 25; the second magnetic block 27 is embedded in the side of the filter plate 11 close to the first magnetic block 26, and the first magnetic block 26 and the second magnetic block 27 are in contact with each other.

[0038] Specifically, the first magnetic block 26 and the second magnetic block 27 are magnetically attracted to each other.

[0039] When the filter plate 11 is inserted into the receiving groove 13, the counterweight 25 causes the cleaning member 14 to automatically droop, causing the first magnetic block 26 to fit into the second magnetic block 27. The first magnetic block 26 and the second magnetic block 27 form a magnetic attraction, temporarily limiting the position and preventing the cleaning member 14 from swinging freely during the insertion of the filter plate 11, ensuring that the groove 24 remains open and facing upward.

[0040] When the clamping block 22 drives the cleaning member 14 to rotate via the groove 24, the force output by the power member 2 causes the first magnetic block 26 and the second magnetic block 27 to disengage from the magnetic engagement, thereby preventing interference with the rotation of the cleaning member 14. Furthermore, the gravity of the counterweight 25 and the magnetic engagement between the first magnetic block 26 and the second magnetic block 27 ensure smooth docking between the groove 24 and the clamping block 22 when the filter plate 11 is inserted into the seating slot 13.

[0041] See also Figure 4 、 Figure 5 and Figure 9As shown, the mounting mechanism includes a guide assembly and a limit assembly; the guide assembly is arranged between the filter plate 11 and the valve body 1, and the guide assembly is used to assist the filter plate 11 to move linearly in the placement groove 13; the limit assembly is arranged between the filter plate 11 and the valve body 1, and the limit assembly is used to limit the filter plate 11 in the placement groove 13; the guide assembly includes an insertion rod 28; the insertion rod 28 is fixedly connected to the filter plate 11; a slot 29 is opened on the side of the valve body 1 close to the insertion rod 28, and the insertion rod 28 can be slidably docked with the slot 29.

[0042] Specifically, the insertion rod 28 and the slot 29 form a sliding guide pair.

[0043] When the filter plate 11 is inserted into the seating groove 13, the filter plate 11 can drive the insertion rod 28 to dock with the slot 29. Since the insertion rod 28 and the slot 29 form a sliding guide pair, the groove 24 can easily maintain stable docking with the block 22. At the same time, the sealing ring 12 and the seating groove 13 can maintain uniform extrusion, and the limiting assembly can stably limit the filter plate 11 and the seating groove 13 together.

[0044] See also Figure 5 、 Figure 6 、 Figure 9 and Figure 10 As shown, the limiting assembly includes a synchronization assembly 210, a through slot 211 and a connecting rod 212; the synchronization assembly 210 is rotatably arranged on the filter plate 11, and the working end of the synchronization assembly 210 is fixedly connected to the knob 2101; the through slots 211 are respectively opened in the rotating ends on both sides of the synchronization assembly 210; the connecting rod 212 is slidably set in the through slot 211; the limiting assembly also includes a first receiving groove 213 and a first screw 214; the first receiving groove 213 is opened on the filter plate 11, and the first receiving groove 213 is used for the connecting rod 21 2 provides sufficient space for the rotation of the connecting rod 212; the first screw 214 is fixedly connected in the first receiving groove 213, and the first screw 214 is threadedly connected to the lower end of the connecting rod 212; the limiting assembly also includes a second receiving groove 215 and a second screw 216; the second receiving groove 215 is opened on the side of the valve body 1 close to the filter plate 11, and the second receiving groove 215 is used to provide sufficient space for the rotation of the connecting rod 212; the second screw 216 is fixedly connected in the second receiving groove 215, and the second screw 216 is threadedly connected to the upper end of the connecting rod 212.

[0045] Specifically, the synchronization assembly 210 is composed of mutually meshing synchronization wheels and a synchronization belt. The through slot 211 and the connecting rod 212 form a sliding guide pair, and the cross-section of the through slot 211 is rectangular.

[0046] When the insertion rod 28 is mated with the slot 29, the connecting rod 212 aligns with the second receiving slot 215. Rotating the knob 2101 now rotates the synchronous pulley in the center of the synchronization assembly 210. The synchronization assembly 210 consists of meshing synchronous pulleys and a timing belt, driving the synchronous pulleys on both sides to rotate synchronously. Because the through slot 211 and the connecting rod 212 form a sliding guide, and the through slot 211 has a rectangular cross-section, the synchronization assembly 210 drives the connecting rod 212 to rotate via the through slot 211.

[0047] The first screw 214 is threadedly connected to the connecting rod 212. As the connecting rod 212 rotates, it moves along the first screw 214 toward the outside of the filter plate 11, allowing the connecting rod 212 to be inserted into the second receiving groove 215. At the same time, the connecting rod 212 docks with the second screw 216 in the second receiving groove 215. Through the threaded connection between the second screw 216 and the connecting rod 212, the connecting rod 212 can rotate and move to the outside of the second screw 216, so that the connecting rod 212 is confined inside the second receiving groove 215, preventing the connecting rod 212 from unnecessary movement or falling off.

[0048] This allows for quick fixation of the filter plate 11 and the valve body 1 , ensuring tight integration of the filter plate 11 and the valve body 1 , and ensuring the stability, sealing, and safety and stability of the valve body 1 during operation.

[0049] Working principle: Before the valve body 1 is put into use, the filter plate 11 is inserted into the placement groove 13. The filter plate 11 forms a sealing structure with the placement groove 13 through the sealing ring 12, so that the insertion rod 28 is docked with the slot 29, and the groove 24 is docked with the block 22. Rotate the knob 2101 to dock the connecting rod 212 with the second screw 216 in the second receiving groove 215, thereby realizing the rapid fixation of the filter plate 11 and the valve body 1. Then start the power part 2, and the block 22 drives the cleaning part 14 to rotate through the groove 24. The cleaning part 14 can sweep away the impurities accumulated on the filter plate 11 to prevent impurities from clogging the filter holes of the filter plate 11, ensuring the efficient operation of the filter plate 11 and ensuring the normal flow of water through the filter plate 11. After the filter plate 11 is removed, the valve body 1 can discharge impurities, and the filter plate 11 and the cleaning part 14 can be cleaned or replaced.

[0050] The above embodiments merely represent one or more embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
