Description

Technical Field

[0001] The invention relates to the technical field of water-saving valves, in particular to a low water hammer effect valve with a spiral turbulent flow channel. Background Art

[0002] Butterfly valves are widely used in agricultural irrigation, often controlling the flow of irrigation water. Installing butterfly valves at the suction or outlet of a water pump facilitates starting and stopping the pump, preventing water waste and equipment damage. Electric butterfly valves, which use electric devices to control the disc's rotation, are a crucial component of automated agricultural irrigation systems. They can be combined with irrigation controllers, sensors, and other devices to enable remote, timed, and automatic control of irrigation.

[0003] In rural areas where power infrastructure is not fully covered or the power supply is unstable, and in mountainous areas where complex terrain makes it difficult to install power lines, diesel engines are often used to power water pumps due to their ease of mobility and ease of use. This is to meet water needs for farmland irrigation, livestock drinking water, and other applications. When a butterfly valve is connected to a diesel-powered water pump pipeline, the engine's speed fluctuates. A sudden increase in speed can increase the water pressure through the valve, creating a significant water hammer effect within the valve. This, over time, can shorten the valve's lifespan. Furthermore, while a timer or timer can be used to control the valve's opening time when the outlet water pressure remains constant, an increase in engine speed, resulting in an increase in water pressure, increases the water flow through the valve per unit time. This, in turn, increases the water flow rate within the same period of time, leading to excessive irrigation water consumption and a waste of water resources.

[0004] Therefore, a low water hammer effect valve with a spiral turbulent flow channel is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a low water hammer effect valve with a spiral turbulence channel, in which the spiral turbulence channel is formed by spiral strips, and when the water pressure changes, the flow channel spacing adjustment component adjusts the spiral spacing of the spiral strips accordingly, and the cross-section adjustment component changes the size of the water flow cross-sectional area inside the valve accordingly. At the same time, it effectively solves the problem that the water pressure increases due to the increase in diesel engine speed, and then a large water hammer effect is formed inside the butterfly valve, thereby shortening the life of the butterfly valve, and the water output per unit time increases, resulting in water resource waste. It has the effect of effectively prolonging the service life of the butterfly valve and reducing the degree of water resource waste caused by the increase in diesel engine speed.

[0006] To achieve the above object, the present invention provides the following technical solutions:

The flow channel spacing adjustment component correspondingly changes the spacing of the spiral strips to restore the water flow pressure to the set value.

The outer frame is fitted on the outer periphery of the valve body, the fixed magnet is fitted in the slide groove, and in the initial state, multiple moving magnets are arranged in the slide groove at equal intervals, multiple vertical bars are respectively fitted on the bottom of the moving magnet, multiple fitting blocks are respectively fitted on the bottom ends of the vertical bars, and the fitting blocks are all slidably arranged on the inner side of the outer frame, and the screw is rotatably arranged between the two ends of the outer frame, and the screw is threadedly connected to multiple vertical bars.

[0009] Preferably, an end gear is installed at the end of the screw, and the end gear is connected to the control motor in a transmission manner. A plurality of threaded portions are provided on the outer periphery of the screw, and the threaded portions are respectively arranged as a, b, c, d, e, f, and g segments along the side of the outer frame away from the moving magnet, and the thread spacing and length between the a, b, c, d, e, f, and g segments increase successively.

[0010] Preferably, the spiral strip includes a plastic strip, a metal block and a memory metal wire. The plastic strip is designed as a spiral structure, and a rectangular groove is opened at the bottom of the plastic strip. The metal block is fitted in the rectangular groove, and the memory metal wire is passed through the inside of the plastic strip.

[0011] Preferably, the number of the metal blocks is equal to the total number of the fixed magnets and the moving magnets, and the positions of the metal blocks coincide with the positions of the moving magnets or the fixed magnets respectively.

[0012] Preferably, the cross-section adjustment assembly includes a fitting ring, a circular hole, a flow rate sensor, a sliding vane, a waterproof motor and a rechargeable battery strip. The fitting ring is fitted on the inner circumference of the valve body, and two circular holes are symmetrically arranged about the center of the fitting ring and opened on the fitting ring. The flow rate sensor is installed in the circular hole, and the sliding vane is slidably arranged in the fitting ring. The waterproof motor is installed on the side of the fitting ring away from the spiral strip. The sliding vane is engaged with the transmission teeth, and the transmission teeth are rotatably arranged in the fitting ring, and the transmission teeth are connected to the output shaft of the waterproof motor through a bevel gear set. The rechargeable battery strip is arranged in the fitting ring.

[0013] Preferably, a silicone ring is attached to the top of the fitting ring, and a charging cable located inside the silicone ring is also installed on the top of the fitting ring. The charging cable is electrically connected to the rechargeable battery bar. A positioning screw is passed through the outer periphery of the fitting ring, and the positioning screw is circumferentially connected to the valve body.

[0014] Preferably, a charging connector is installed on the top of the valve body, and the charging connector is connected to the charging cable.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention is mainly used in rural areas where power infrastructure has not yet been fully covered or the power supply is unstable, as well as in mountainous areas where complex terrain makes it difficult to install power lines. When a diesel engine is used to provide power input for the water pump due to the difficulty in installing the circuit, the cooperation of the spiral strips and the flow channel spacing adjustment component can effectively reduce the water hammer effect formed inside the butterfly valve due to the sudden increase in the speed of the diesel engine, thereby effectively extending the service life of the butterfly valve. At the same time, when the water pressure fluctuates, the water flow pressure can be adjusted to the set value in time, thereby avoiding the increase in irrigation water consumption due to the increase in water pressure in a short period of time, thereby achieving the effect of saving irrigation water.

[0017] 2. Through the arrangement of the spiral strips, when the butterfly valve is closed, the fluid generates a secondary flow during the flow process, which increases the degree of disturbance of the fluid and thus increases the flow resistance of the fluid. Then, by reducing the water flow pressure, the water hammer effect inside the butterfly valve is effectively reduced. Moreover, when the speed of the diesel engine increases suddenly, with the cooperation of the flow channel spacing adjustment component, the change in the spiral pitch of the spiral strips gradually increases along the direction from the water inlet to the water outlet of the butterfly valve, that is, the spiral pitch on the side close to the cross-section adjustment component is much smaller than the spiral pitch on the side away from the cross-section adjustment component. By adjusting the spiral pitch, the adjustment range of the spiral strips on the water flow pressure can be greatly improved, thereby effectively avoiding the waste of water resources caused by a large excess of irrigation water due to a sudden increase in the speed of the diesel engine.

[0018] 3. Through the cross-section adjustment component, since it takes a certain amount of time for the flow channel spacing adjustment component to adjust the spiral pitch of the spiral strip, in order to reduce the waste of irrigation water in this process, the cross-section adjustment component can quickly change the cross-sectional area of the water flow inside the valve body, further improving the water-saving effect.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 8 The present invention provides a low water hammer effect valve with a spiral turbulent flow channel. The technical solution is as follows:

[0030] Reference Figure 1 and Figure 2 A low water hammer effect valve with a spiral turbulent flow channel includes a valve body 1, a valve seat 2, and a controller 3. The valve body 1 is made of stainless steel. Although the overall cost is relatively high, considering the usage scenario, for remote mountainous areas and underdeveloped rural areas, the stainless steel valve body 1 has a longer overall service life and a lower overall weight. During the transportation process after purchase, the burden of manual handling can be significantly reduced. The valve seat 2 is installed on the outer periphery of the valve body 1 and is arranged on the side close to the water outlet of the valve body 1. The controller 3 is installed on the side wall of the valve seat 2. It also includes a spiral strip 4 and a flow channel spacing adjustment component 5. , cross-section adjustment component 6 and control motor 7, the outer periphery of the valve body 1 is provided with a chute 11, the spiral strip 4 is fitted in the valve body 1, and the end of the spiral strip 4 close to the water outlet of the valve body 1 is fixedly fitted with the valve body 1, the flow channel spacing adjustment component 5 is fitted on the outer periphery of the valve body 1, and the chute 11 is located inside the flow channel spacing adjustment component 5, the cross-section adjustment component 6 is installed on the inner periphery of the valve body 1, the control motor 7 is installed on the side of the valve seat 2 close to the flow channel spacing adjustment component 5, and the control motor 7 is connected to the flow channel spacing adjustment component 5 by transmission, and the flow channel spacing adjustment component 5 is adsorbed by the spiral strip 4 through magnetic force. The chute 11 is located on the inner side of the flow channel spacing adjustment component 5, so the minimum distance between the flow channel spacing adjustment component 5 and the spiral strip 4 is the position where the chute 11 is opened on the valve body 1. Combined with the material design of the valve body 1, it can effectively ensure the adsorption effect between the flow channel spacing adjustment component 5 and the spiral strip 4 through the magnetic force, thereby ensuring that the flow channel spacing adjustment component 5 can change the spiral pitch of the spiral strip 4 accordingly when it is working. When the water pressure inside the valve body 1 changes, the cross-section adjustment component 6 adaptively adjusts the flow cross-sectional area, and the control motor 7 provides power input for the flow channel spacing adjustment component 5. The flow channel spacing adjustment component 5 corresponds to The spacing of the spiral strips 4 is changed to restore the water flow pressure to the set value. When the spiral spacing of the spiral strips 4 changes, the water flow speed can be gradually reduced under the action of the spiral strips 4 whose outer periphery is close to the inner wall of the valve body 1, and then the water pressure inside the valve body 1 is adjusted to an appropriate numerical range, thereby effectively reducing the water hammer effect inside the valve body 1. In addition, in the process of the flow channel spacing adjustment component 5 changing the spiral spacing of the spiral strips 4, the cross-section adjustment component 6 can respond quickly and adjust the internal water flow cross-sectional area of the valve body 1 in advance, thereby avoiding the waste of irrigation water caused in this process and achieving the purpose of saving water.

[0031] Reference Figure 3As an embodiment of the present invention, specifically, the flow channel spacing adjustment component 5 includes an outer frame 51, a fixed magnet 52, a moving magnet 53, a vertical bar 54, a fitting block 55 and a screw 56. The outer frame 51 is fitted on the outer periphery of the valve body 1, and the edge of the inner wall of the outer frame 51 is flush with the edge of the slide groove 11. The fixed magnet 52 is fitted in the slide groove 11. In the initial state, multiple moving magnets 53 are arranged at equal intervals in the slide groove 11. The position of the fixed magnet 52 is fixed, and the spacing of the moving magnets 53 can be adjusted. Multiple vertical bars 54 are respectively fitted on the bottom of the moving magnet 53, and multiple fitting blocks 55 are respectively fitted on the bottom ends of the vertical bars 54. The fitting blocks 55 are all slidably arranged on the inner side of the outer frame 51. The screw 56 is rotatably arranged between the two ends of the outer frame 51, and the screw 56 is threadedly connected to the multiple vertical bars 54. Figure 4 , an end gear 561 is installed at the end of the screw 56, and the end gear 561 is connected to the large gear on the output shaft of the control motor 7. A plurality of threaded portions 562 are provided on the outer periphery of the screw 56. The threaded portions 562 are respectively arranged as a, b, c, d, e, f, and g segments along the side of the outer frame 51 away from the moving magnet 53, and the thread pitch and length between the a, b, c, d, e, f, and g segments increase in sequence, and the rotation direction of the threaded portion 562 is consistent. When the screw 56 rotates, the bonding block 55 Under the limiting action, the vertical bar 54 threadedly connected to the screw 56 moves linearly along the inner wall of the outer frame 51, thereby simultaneously changing the positions of the vertical bar 54, the fitting block 55 and the moving magnet 53 in the outer frame 51. Since the rotation direction of the threaded portion 562 is consistent, and the thread pitch and length increase successively, when the screw 56 rotates, the movement spacing of the vertical bar 54 fitted with the threaded portion 562 of sections a, b, c, d, e, f, and g also increases successively, and the spiral pitch at the end of the spiral bar 4 close to the water inlet changes the least.

[0032] Reference Figure 5As an embodiment of the present invention, specifically, the spiral strip 4 includes a plastic strip 41, a metal block 42 and a memory wire 43. The plastic strip 41 is designed as a spiral structure, and a rectangular groove is opened at the bottom of the plastic strip 41. The metal block 42 is fitted in the rectangular groove. The metal block 42 is made of an iron block and can be fixed by adsorption with a magnet. The memory wire 43 is passed through the inside of the plastic strip 41. Under the action of the memory wire 43, the plastic strip 41 can quickly return to its original shape when it is reset after radial deformation. The number of metal blocks 42 is equal to the total number of fixed magnets 52 and moving magnets 53, and the position of the metal block 42 coincides with the position of the moving magnet 53 or the fixed magnet 52 respectively. The distance between the metal block 42 and the moving magnet 53 and the fixed magnet 52 is the thickness of the valve body 1 and the distance between the slide groove 11 The difference in depth means that when the position of the moving magnet 53 changes accordingly, the corresponding metal block 42 moves a corresponding distance under the magnetic force of the moving magnet 53. Therefore, when the screw 56 rotates, the metal blocks 42 corresponding to the threaded portions 562 of sections a, b, c, d, e, f, and g move different distances. The metal block 42 close to the water inlet moves the smallest distance, and the metal block 42 away from the water inlet and not in contact with the fixed magnet 52 moves the largest distance. As a result, the spiral pitch of the plastic strip 41 changes sequentially, causing the water flow rate to gradually decrease as the spiral pitch of the plastic strip 41 gradually decreases when the water flows through the plastic strip 41, thereby reducing the water flow pressure in the valve body 1, effectively reducing the water hammer effect in the valve body 1, and greatly extending the service life of the valve body 1.

[0033] Reference Figure 6 、 Figure 7 and Figure 8As an embodiment of the present invention, specifically, the cross-section adjustment component 6 includes a fitting ring 61, a circular hole 62, a flow rate sensor 63, a slide 64, a waterproof motor 65 and a rechargeable battery strip 66. The fitting ring 61 is fitted on the inner circumference of the valve body 1, and the side of the fitting ring 61 close to the water inlet is a conical surface so that water flows through the fitting ring 61 quickly. The two circular holes 62 are symmetrically arranged about the center of the fitting ring 61 and are opened on the fitting ring 61. The flow rate sensor 63 is installed in the circular hole 62. The flow rate sensor 63 is electrically connected to the controller 3 and is used to reflect the water flow pressure by detecting the water flow velocity at this position, and then adjust the rotation direction and number of rotations of the waterproof motor 65 through the controller 3. The slide 64 is slidably arranged in the fitting ring 61. The slide 64 is tilted. The waterproof motor 65 is installed on the side of the fitting ring 61 away from the spiral strip 4. The slide 64 is meshed with the transmission gear 651 The transmission tooth 651 is rotatably arranged in the fitting ring 61, and the transmission tooth 651 is connected to the output shaft of the waterproof motor 65 through a bevel gear set. The bevel gear set consists of two bevel gears, one bevel gear is coaxially arranged with the transmission tooth 651, and the other bevel gear is installed on the output shaft of the waterproof motor 65. When the output shaft of the waterproof motor 65 rotates, it drives the transmission tooth 651 to rotate through the bevel gear set. The transmission tooth 651 contacts the tooth groove of the side wall of the slide 64 and drives the slide 64 to move. When the slide 64 moves toward the center of the fitting ring 61, the cross-sectional area of the inner side of the fitting ring 61 becomes smaller. When the slide 64 moves toward the inner side of the fitting ring 61, the cross-sectional area of the inner side of the fitting ring 61 becomes larger. The maximum cross-sectional area is the inner circumferential area of the fitting ring 61. The rechargeable battery bar 66 is arranged in the fitting ring 61. The rechargeable battery bar 66 is electrically connected to the waterproof motor 65 and the control motor 7 and is used as the power supply for the butterfly valve.

[0034] Reference Figure 6 As an embodiment of the present invention, specifically, a silicone ring 121 is bonded to the top of the fitting ring 61, and a charging line 122 located inside the silicone ring 121 is also installed on the top of the fitting ring 61. The charging line 122 is electrically connected to the rechargeable battery bar 66. A positioning screw 123 is passed through the outer periphery of the fitting ring 61, and the positioning screw 123 is screwed into the inner periphery of the valve body 1. The positioning ring and the valve body 1 are fixed by the positioning screw 123. A hole for passing the charging line 122 is opened on the valve body 1, and the hole and the charging line 122 are both located inside the silicone ring 121. Therefore, under the action of the silicone ring 121, liquid leakage can be prevented from occurring at the hole of the valve body 1.

[0035] Reference Figure 1 and Figure 6As an embodiment of the present invention, specifically, a charging connector 12 is installed on the top of the valve body 1, and the charging connector 12 is connected to the charging line 122. The designed charging connector 12 and charging line 122 facilitate regular charging of the rechargeable battery bar 66, and the charging connector 12 uses a USB connector, which facilitates the use of power banks and other devices to charge the rechargeable battery bar 66 in remote mountainous areas.

[0036] Working principle: This butterfly valve is mainly suitable for rural areas where power infrastructure has not yet been fully covered or power supply is unstable, as well as mountainous areas where complex terrain makes it difficult to lay power lines. When in use, it is installed on the water pump pipeline with diesel engine as power input. During agricultural irrigation, the working time of the diesel engine is set by a timer during night irrigation. When the water pressure increases accordingly due to a sudden increase in the speed of the diesel engine, the cross-section adjustment component 6 with the flow rate sensor 63 feeds back the water flow velocity data on the outlet side of the valve body 1 to the controller 3. The controller 3 adjusts the flow channel spacing adjustment component 5 and the cross-section adjustment component 6 accordingly. The cross-section adjustment component 6 changes the size of its internal flow cross-sectional area in advance to reduce the water flow rate per unit time, avoid wasting irrigation water, and achieve the purpose of saving water. In this process, the flow channel spacing adjustment component 5 adjusts the spiral pitch of the spiral strip 4 accordingly to reduce the water hammer effect on the valve disc in the valve body 1.

[0037] Specifically, when the cross-section adjustment component 6 is started, the output shaft of the waterproof motor 65 powered by the rechargeable battery bar 66 rotates, which drives the transmission teeth 651 to rotate through the bevel gear set. The transmission teeth 651 contact the tooth grooves on the side wall of the slide 64 and drive the slide 64 to move toward the center of the fitting ring 61, so that the cross-sectional area inside the fitting ring 61 becomes smaller; at the same time, the output shaft of the control motor 7 drives the screw 56 to rotate through the large gear and the end gear 561. During the rotation of the screw 56, the movement spacing of the vertical bars 54 that fit with the threaded parts 562 of sections a, b, c, d, e, f, and g increases in sequence, and the moving distance of the moving magnet 53 is the same as that of the corresponding vertical bars 54. The moving pitch of the plastic strip 41 is equal to that of the moving magnet 53. The moving magnet 53 changes the position of the corresponding metal block 42 through magnetic attraction, so that the spiral pitch of the plastic strip 41 is consistent with the pitch of the threaded portion 562 of sections a, b, c, d, e, f, and g. When water flows through the plastic strip 41 with a changing spiral pitch, the spiral pitch of the plastic strip 41 gradually decreases, resulting in a gradual decrease in the water flow velocity between the plastic strips 41, thereby reducing the water flow pressure and water hammer effect in the valve body 1, thereby significantly extending the service life of the valve body 1. After the plastic strip 41 is adjusted, the controller 3 controls the waterproof motor 65 to rotate in the opposite direction to reset the slide 64 to the fitting ring 61.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
