Description

Technical Field

[0001] This invention relates to the field of valve technology, specifically to a valve that is easy to clean and drain, and its method of use. Background Technology

[0002] Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, and pressure relief. Used in fluid control systems, valves can control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media. Therefore, valves are widely used.

[0003] In daily life, for example, people usually install valves at the outlet of water pipes to control the water flow for convenience. However, water generally contains certain impurities. In the current technology, most ordinary valves do not have the function of filtering impurities, so valve blockage is prone to occur. Although some valves have a filtering function, the impurities filtered inside are not easy to clean. Without a corresponding impurity discharge mechanism, relying solely on gravity to clean impurities is not enough to clean them thoroughly, and impurities can easily accumulate, thereby affecting the filtration efficiency and filtration quality of the valve. Summary of the Invention

[0004] To address the problems existing in the prior art, a valve that facilitates cleaning and sewage discharge, and its usage method, are provided.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] This invention proposes a valve for easy cleaning and sewage discharge, comprising a valve body with an inlet and an outlet, and a flow port. The inlet is connected to the outlet via the flow port, and a valve core is slidably connected to the valve body above the flow port. A main shaft is movably mounted on the valve body, with a handwheel connected to the upper end of the main shaft extending out of the valve body. A first gear is fixedly mounted on the bottom end of the main shaft, and a second gear that meshes with the first gear is rotatably connected to the valve body. The second gear is threadedly connected to the valve core. A filter screen is provided inside the flow port, and a rotating rod is movably mounted inside the valve core. A brush is fixedly connected to the bottom end of the rotating rod, which is positioned below the filter screen. A third gear that meshes with the first gear is fixedly connected to the upper end of the rotating rod.

[0007] Preferably, the valve body is slidably connected to a vertically movable sealing plate, and a flushing channel is provided on one side of the sealing plate. The flushing channel is located above the water inlet and is connected to the water inlet. The sealing plate has a backflushing channel that cooperates with the flushing channel.

[0008] Preferably, the valve body also has a drain port located below the water inlet, and the valve body is also slidably connected to a horizontally movable drain plate, which is slidably disposed within the drain port.

[0009] Preferably, the valve body is slidably connected to a vertically movable sliding block, the sliding block is located directly below the sealing plate, the sliding block is connected to the valve body through a first spring, and the sliding block is used to drive the sewage discharge plate to move.

[0010] Preferably, a first rack is connected to one side of the sliding block, a second rack is connected to one side of the drain plate, a sixth gear is rotatably connected to the valve body, and a seventh gear is coaxially connected to the sixth gear; the sixth gear meshes with the first rack, the seventh gear meshes with the second rack, and the diameter of the sixth gear is smaller than the diameter of the seventh gear.

[0011] Preferably, the valve body is rotatably connected to a fifth gear and a fourth gear, the fifth gear is internally threaded to a screw, the bottom end of the screw is fixedly connected to the sealing plate, and the two ends of the fourth gear are respectively engaged with the fifth gear and the third gear.

[0012] Preferably, the main shaft has a groove, and a steel ball is slidably connected in the groove. The steel ball is connected to the main shaft by a second spring. The valve body also has a first annular groove and a second annular groove that are adapted to the steel ball.

[0013] Preferably, when the steel ball is located in the first annular groove, the first gear and the second gear mesh with each other, and when the steel ball is located in the second annular groove, the first gear meshes with the third gear.

[0014] This invention also proposes a method for using a valve that facilitates cleaning and sewage discharge. The method, employing the aforementioned valve, includes the following steps:

[0015] When the valve is in normal use:

[0016] The steel ball is located in the first annular groove. The first gear and the second gear mesh with each other. The handwheel drives the main shaft to rotate. The main shaft drives the second gear to rotate through the first gear. The second gear drives the valve core to move vertically. The valve core realizes the opening and closing of the water inlet.

[0017] When the valve needs to be cleaned:

[0018] S1: Control the valve core to move, close the water outlet, pull the main shaft upward, move the steel ball into the second annular groove, disengage the first gear and the second gear, and engage the first gear with the third gear;

[0019] S2: The main shaft is driven to rotate by the handwheel. The main shaft drives the third gear to rotate through the first gear. The third gear drives the brush to rotate through the rotating rod, so that the filter screen can work. At the same time, the third gear drives the fifth gear to rotate through the fourth gear. The fifth gear drives the screw and the sealing plate to move downward. The sealing plate drives the sliding block.

[0020] S3: As the main shaft continues to rotate, the sealing plate drives the sliding block to move downward. The sliding block drives the seventh gear to rotate through the sixth gear. The seventh gear drives the drain plate to move, opening the drain port. At this time, the water inlet is connected to the backwash channel and the flushing channel.

[0021] S4: As water flows in from the inlet, it enters the flushing channel through the backwash channel, and then enters the space above the filter screen. Under the action of the water flow, the filter screen is flushed. After that, the water flows out from the drain outlet, thus completing the valve cleaning work.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention is equipped with a main shaft, on which a first gear is mounted. When the first gear and the second gear mesh, the main shaft can drive the second gear to rotate, thereby driving the valve core to move vertically and realize the opening and closing of the water inlet. When the first gear and the third gear mesh, the main shaft can drive the rotating rod to rotate through the third gear, thereby driving the brush to rotate, which can realize the cleaning of the filter screen, prevent the filter screen from clogging, and thus improve the efficiency and quality of impurity filtration.

[0024] 2. This invention features a vertically movable sealing plate. The main shaft can drive the sealing plate to move vertically via a third gear, thereby causing the backwash channel to move downwards. This connects the inlet to the flushing channel, allowing water to flow into the filter screen and perform backwashing. Simultaneously, the sealing plate can also move the sliding block, which in turn moves the drain plate horizontally, opening the drain port to facilitate the discharge of impurities after flushing. This removes impurities from the valve, preventing excessive impurities from affecting the filter screen's filtration efficiency and achieving valve body cleaning. Attached Figure Description

Detailed Implementation

[0031] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] like Figure 1-3 As shown, this embodiment proposes a valve that is easy to clean and discharge sewage, including a valve body 1. The valve body 1 has an inlet 2 and an outlet at both ends. The middle part of the valve body 1 also has a through-hole 18. The inlet 2 is connected to the outlet through the through-hole 18. The inlet 2 is connected to the inlet end, and the outlet is connected to the outlet end.

[0033] A valve core 17 is provided above the water inlet 18 and is slidably connected to the valve body 1. The valve core 17 can only slide in the vertical direction of the valve body 1 and will not rotate. The opening and closing of the water inlet 18 can be realized by the movement of the valve core 17.

[0034] A main shaft 14 is movably mounted on the valve body 1. A handwheel 11 is connected to the upper end of the main shaft 14 after it passes through the valve body 1. A first gear 16 is fixedly mounted on the bottom end of the main shaft 14. A second gear 15 that cooperates with the first gear 16 is rotatably connected to the valve body 1. The second gear 15 is threadedly connected to the valve core 17.

[0035] The main shaft 14 and the valve body 1 are slidably and rotatably connected. The main shaft 14 can slide vertically along the valve body 1 and can also rotate relative to the valve body 1. The second gear 15 has a thread in the middle part, through which the second gear 15 is threadedly connected to the valve core 17. The second gear 15 can only rotate, so when the main shaft 14 drives the second gear 15 to rotate through the first gear 16, it can drive the valve core 17 to move vertically.

[0036] A filter screen 19 is installed inside the water inlet 18. The filter screen 19 is located below the water inlet 18. The water flowing in from the inlet 2 will pass through the filter screen 19 before entering the outlet through the water inlet 18.

[0037] A rotating rod 20 is movably mounted inside the valve core 17. A brush 21 is fixedly connected to the bottom end of the rotating rod 20 and is positioned below the filter screen 19. A third gear 9, which meshes with the first gear 16, is fixedly connected to the upper end of the rotating rod 20. The brush 21 and the filter screen 19 are compatible, with the length of the brush 21 being the same as the radius of the filter screen 19. When the brush 21 rotates one revolution, the entire filter screen 19 can be cleaned.

[0038] The rotating rod 20 and the valve core 17 are slidably and rotatably connected. The upper end of the rotating rod 20 is rotatably connected to the valve body 1 through a bearing. The rotating rod 20 can rotate around the valve body 1. When the valve core 17 moves vertically, the valve core 17 can slide relative to the rotating rod 20. When the main shaft 14 drives the third gear 9 to rotate through the first gear 16, the third gear 9 can drive the rotating rod 20 to rotate, thereby driving the brush 21 to rotate, realizing the cleaning work of the filter screen 19.

[0039] The valve body 1 is slidably connected to a vertically movable sealing plate 5. A flushing channel is provided on one side of the sealing plate 5. The flushing channel is located above the water inlet 18 and is connected to the water inlet 18. The sealing plate 5 has a backwash channel 4 that cooperates with the flushing channel.

[0040] The sealing plate 5 can only slide vertically along the valve body 1. The backwash channel 4 is set in an inclined direction. In the initial state, the sealing plate 5 is located inside the valve body 1, so as not to affect the normal water outlet operation. At this time, the two sides of the backwash channel 4 are in contact with the valve body 1, the backwash channel 4 is closed, and one end of the flushing channel is in contact with the sealing plate 5, thus realizing the closure of one end of the flushing channel.

[0041] The flushing channel is located between the inlet 18 and the filter screen 19. Therefore, when the inlet 2 and the flushing channel are connected through the backwash channel 4, the water flow can fall from the filter screen 19 to backwash the filter screen 19 without affecting the inlet 18.

[0042] The valve body 1 is also provided with a drain port located below the water inlet 18. The valve body 1 is also slidably connected to a horizontally movable drain plate 22. The drain plate 22 is slidably located in the drain port. The valve body 1 is provided with a small groove. In the initial state, the right end of the drain plate 22 is located in the small groove, and the drain plate 22 keeps the drain port in a closed state.

[0043] The valve body 1 is slidably connected to a vertically moving sliding block 3, which is located directly below the sealing plate 5. The sliding block 3 is connected to the valve body 1 through a first spring 28 and is used to drive the drain plate 22 to move.

[0044] A vertical rod is fixedly connected to the lower end of the sliding block 3. The first spring 28 is sleeved on the vertical rod. The upper end of the first spring 28 is connected to the lower end of the sliding block 3, and the lower end of the first spring 28 is connected to the valve body 1. In the initial state, the sliding block 3 is located inside the valve body 1, so as not to affect the normal water output operation.

[0045] A first rack 23 is connected to one side of the sliding block 3, and a second rack 26 is connected to one side of the drain plate 22. A sixth gear 24 is rotatably connected to the valve body 1, and a seventh gear 25 is coaxially connected to the sixth gear 24. The sixth gear 24 meshes with the first rack 23, and the seventh gear 25 meshes with the second rack 26. The diameter of the sixth gear 24 is much smaller than the diameter of the seventh gear 25, so that when the sliding block 3 moves a small distance, it can drive the drain plate 22 to move a large distance.

[0046] When the sealing plate 5 moves the sliding block 3 vertically, the first rack 23 drives the sixth rack 24 to rotate, which in turn drives the second rack 26 to move via the seventh gear 25. The second rack 26 then moves the drain plate 22 to the left, thus opening the drain outlet. When the sealing plate 5 is no longer in contact with the sliding block 3, the sliding block 3 is reset by the action of the first spring 28, which in turn moves the drain plate 22 to the right, closing the drain outlet.

[0047] The valve body 1 is rotatably connected to the fifth gear 6 and the fourth gear 8. The fifth gear 6 is internally threaded to the screw 7. The bottom end of the screw 7 is fixedly connected to the sealing plate 5. The two ends of the fourth gear 8 are respectively meshed with the fifth gear 6 and the third gear 9. The fifth gear 6 is internally threaded and is threaded to the screw 7 through the thread 7. The fifth gear 6 can only rotate, thereby driving the screw 7 to move vertically.

[0048] The main shaft 14 has a groove, and a steel ball 12 is slidably connected in the groove. The steel ball 12 is connected to the main shaft 14 through a second spring 13. The valve body 1 also has a first annular groove 27 and a second annular groove 10 that are adapted to the steel ball 12.

[0049] When the steel ball 12 is located in the first annular groove 27, the first gear 16 and the second gear 15 mesh, which can drive the valve core 17 to move vertically and realize the opening and closing of the water outlet 18.

[0050] When the steel ball 12 is located in the second annular groove 10, the first gear 16 meshes with the third gear 9, which can drive the rotating rod 20 to rotate, drive the sealing plate to move vertically, realize the connection between the water inlet 2 and the backwash channel 4, open the sewage outlet, and realize the rinsing of the filter screen 19.

[0051] The second spring 13 is used for the reset of the steel ball 13. Under the action of the second spring 13, the steel ball 13 can be moved into the first annular groove 27 or the second annular groove 10, thereby achieving the relative fixation of the height of the main shaft 14, thereby driving the second gear 15 or the third gear 9 to rotate.

[0052] This invention also proposes a method for using a valve that facilitates cleaning and sewage discharge, and further includes the aforementioned valve for easy cleaning and sewage discharge, comprising the following steps:

[0053] When the valve is in normal use:

[0054] The steel ball 12 is located in the first annular groove 27. The first gear 16 and the second gear 15 mesh with each other. The handwheel 11 drives the main shaft 14 to rotate. The main shaft 14 drives the second gear 15 to rotate through the first gear 16. The second gear 15 drives the valve core 17 to move vertically. The valve core 17 realizes the opening and closing of the water outlet 18.

[0055] When the valve needs to be cleaned:

[0056] S1: Control valve core 17 to move, close water outlet 18, pull main shaft 14 upward, move steel ball 12 into second annular groove 10, disengage first gear 16 and second gear 15, and engage first gear 16 with third gear 9.

[0057] S2: The main shaft 14 is driven to rotate by the handwheel 11. The main shaft 14 drives the third gear 9 to rotate through the first gear 16. The third gear 9 drives the brush 21 to rotate through the rotating rod 20, so that the filter screen 19 can work. At the same time, the third gear 9 drives the fifth gear 6 to rotate through the fourth gear 8. The fifth gear 6 drives the screw 7 and the sealing plate 5 to move downward. The sealing plate 5 drives the sliding block.

[0058] S3: As the main shaft 14 continues to rotate, the sealing plate 5 drives the sliding block 3 to move downward. The sliding block 3 drives the seventh gear 25 to rotate through the sixth gear 24. The seventh gear 25 drives the drain plate 22 to move, so that the drain port is opened. At this time, the water inlet 2 is connected to the flushing channel through the backwash channel 4.

[0059] S4: As water flows in from the inlet 2, it enters the flushing channel through the backwash channel 4, and then enters the space above the filter screen 19. Under the action of the water flow, the filter screen 19 is flushed. After that, the water flows out from the drain port, thus completing the cleaning of the valve.

[0060] It should be noted that the main shaft 14 is equipped with a first gear 16. When the first gear 16 and the second gear 15 mesh, the main shaft 14 can drive the second gear 15 to rotate, thereby driving the valve core 17 to move vertically and realize the opening and closing of the water outlet 18. When the first gear 16 and the third gear 9 mesh, the main shaft 14 can drive the rotating rod 20 to rotate through the third gear 9, thereby driving the brush 21 to rotate, which can realize the cleaning of the filter screen 19, prevent the filter screen 19 from clogging, and thus improve the efficiency and quality of impurity filtration.

[0061] In addition, the main shaft 14 can drive the sealing plate 5 to move vertically through the third gear 9, thereby driving the backwash channel 4 to move downward, so that the water inlet 2 is connected to the flushing channel through the backwash channel 4. At this time, the water flow in the water inlet 2 can enter the filter screen 19 above, thereby achieving backwashing of the filter screen 19. At the same time, the sealing plate 5 can also drive the sliding block 3 to move, thereby driving the drain plate 22 to move horizontally, so that the drain port is opened, making it easy to discharge the impurities after flushing through the drain port, thereby realizing the discharge of impurities in the valve, preventing excessive impurities from affecting the filtration efficiency of the filter screen 19, and realizing the cleaning of the valve body 1.

[0062] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
