Description

Technical Field

[0001] The invention relates to the technical field of liquid transmission, in particular to a manual and electric dual-purpose pipeline valve for diversion. Background Art

[0002] A ball valve is a valve in which a spherical opening and closing member is driven by a valve stem and rotates around the axis of the ball valve. It is usually used in hydraulic pipelines or fluid delivery pipelines. It is widely used in the petroleum, chemical, metallurgy and other industries because of its quick and easy opening and closing and strong flexibility. There are two types of ball valves, one is a two-way L-shaped ball valve, and the other is a three-way T-shaped ball valve.

[0003] Current pipeline ball valves are unable to achieve efficient graded retention and directional diversion of large-diameter suspended particulate matter during use. Because traditional ball valves are only equipped with a single filtering structure, when processing high-solids fluids, large particle impurities can easily cause filter blockage and disrupt the flow balance, forcing downstream processes to add primary treatment units such as sedimentation tanks for pre-filtration, resulting in lengthy process flows and doubled energy consumption. Summary of the Invention

[0004] In order to solve the problem in the background art that the pipeline ball valve cannot filter large-diameter suspended particulate matter in a circular manner, the present invention aims to provide a valve.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a manual and electric dual-purpose pipeline valve for diversion, comprising a first ball valve, a second ball valve, a third ball valve, and a fourth ball valve, wherein the first ball valve and the fourth ball valve each have a T-shaped channel in their balls, and the second ball valve and the third ball valve each have an L-shaped channel in their balls; The first valve body of the first ball valve is provided with a first water inlet, a first water outlet and a second water outlet, the second valve body of the second ball valve is provided with a second water inlet, a third water outlet and a fourth water outlet, the third valve body of the third ball valve is provided with a third water inlet, a fifth water outlet and a sixth water outlet, and the fourth valve body of the fourth ball valve is provided with a fourth water inlet, a fifth water inlet, a seventh water outlet and an eighth water outlet; The first water outlet is connected to the fourth water outlet through the first connecting pipe, the second water outlet is connected to the third water inlet through the second connecting pipe, the second water inlet is connected to the fourth water inlet through the fourth connecting pipe, and the fifth water outlet is connected to the fifth water inlet through the fifth connecting pipe; The first gear, the second gear, the third gear and the fourth gear are fixed to the rotating shafts of the first ball valve, the second ball valve, the third ball valve and the fourth ball valve respectively, and the first gear, the second gear, the third gear and the fourth gear are meshed and linked by a chain; The rotating shaft of the first ball valve is connected to a manual rotating wheel and a servo drive assembly. The servo drive assembly includes a servo motor, a reducer, an electromagnetic clutch and a fifth rotating shaft meshing with the fifth gear.

[0006] Furthermore, a first filter cup is provided in the T-shaped channel of the first ball valve, a second filter cup is provided at one end of the L-shaped channel of the second ball valve, a third filter cup is provided at one end of the L-shaped channel of the third ball valve, and a fourth filter cup is provided in the T-shaped channel of the fourth ball valve.

[0007] Furthermore, the first water inlet of the first valve body is connected to the water inlet pipe, the third water outlet of the second valve body is connected to the first miscellaneous pipe, the sixth water outlet of the third valve body is connected to the second miscellaneous pipe, the seventh water outlet of the fourth valve body is connected to the third miscellaneous pipe, and the eighth water outlet is connected to the clean pipe.

[0008] Furthermore, the servo drive assembly further includes a signal transmitter, which is engaged with the first thread of the fifth rotating shaft through the sixth rotating shaft and the second thread.

[0009] Furthermore, a protective shell covering the gear is provided on the outside of the chain, and the protective shell is fixed on the first valve body.

[0010] Furthermore, the servo motor, the reducer and the electromagnetic clutch are integrated in the housing, and the housing is fixed on the first valve body.

[0011] Furthermore, it also includes a base plate, on which four groups of fixing bolts are provided, and each group of fixing bolts respectively fixes the first ball valve, the second ball valve, the third ball valve and the fourth ball valve through a pressure plate.

[0012] Furthermore, the contact surface between the pressure plate and the ball valve body is provided with an anti-slip cushion layer.

[0013] Furthermore, the gear ratio of the first gear, the second gear, the third gear and the fourth gear is 1:1:1:1.

[0014] Furthermore, the electromagnetic clutch is configured to automatically switch to a manual drive mode when power is cut off.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention includes four spherical valve bodies with differentiated filter cups. The ball core inside each valve body forms a transmission system through gears and chains, and realizes four-valve linkage based on the principle of synchronous transmission; the servo motor drives the first ball valve to rotate at a certain angle through a planetary reducer and an electromagnetic clutch, and transmits the motion parameters proportionally to the other three valves with the help of a chain transmission system. The linkage mechanism enables the flow direction of the four groups of ball valves to be switched in combination, forming a variety of flow channel configurations including forward filtration and reverse flushing; the T-shaped / L-shaped combined flow channel in the sphere is combined with a gradient filtration device (filtration accuracy 2mm→1mm→0.5mm), which can dynamically grade and intercept impurities of different particle sizes in the fluid. In combination with the turbidity signal feedback from the pressure sensor, the system can automatically select the optimal flow channel combination to realize intelligent diversion of fluid with a solid phase impurity content of 0.5%-15%, greatly shortening the process flow.

[0016] This invention features an innovative backwash self-cleaning function. By integrating a pressure sensing module with a time-per-unit control algorithm, it monitors the pressure differential across the four valve body filter cups in real time. During the backwash process, the servo drive system switches the four valve flow paths to reverse flush mode, using pulsed pressure waves to flush the filter screens. This process thoroughly removes large particle clusters trapped in the honeycomb flow path of the first filter cup, medium-sized impurities in the second and third filter cups, and small impurities in the fourth filter cup, effectively extending the service life of the filter cups.

[0059] When this embodiment is used ( Figure 7 - Figure 12 In the figure, the black arrow indicates the direction of liquid flow; Figure 13 - Figure 24 In the figure, the black arrows indicate the flow direction of the liquid to be filtered, the white arrows indicate the flow direction of the clean water, the quadrilateral impurities represent large particles of impurities, the triangular impurities represent medium particles of impurities, and the circular impurities represent small particles of impurities. The first sphere 202, the second sphere 302, the third sphere 402, and the fourth sphere 502 are all provided with pressure sensors that reflect turbidity signals, and the configuration of the flow channel is controlled by the pressure sensors. In the following steps, the clean liquid refers to the liquid to be filtered from which suspended impurities have been removed. The steps are as follows: Step 1: The liquid to be filtered first enters the first sphere 202 through the water inlet pipe 206. After being filtered by the first filter cup 207, the liquid to be filtered is split into two streams and flows through the first connecting pipe 601 and the second connecting pipe 602 to the second ball valve 300 and the third ball valve 400 respectively. One stream of the liquid to be filtered enters the second sphere 302 and is filtered by the second filter cup 307. The other stream of the liquid to be filtered enters the third sphere 402 and is filtered by the third filter cup 407. Both streams of the liquid to be filtered enter the fourth sphere 502, are filtered by the fourth filter cup 507, and are discharged through the outlet pipe 508. Step 2: After running for a set unit time according to the method of step 1 (or until the difference between the pressure sensors in the second sphere 302, the third sphere 402, the fourth sphere 502 and the first sphere 202 is twice), refer to Figure 13 A large amount of impurities will remain in the first filter cup 207, the second filter cup 307, the third filter cup 407 and the fourth filter cup 507. The impurities in the first filter cup 207 are large particles (refer to Figure 13 The impurities in the second filter cup 307 and the third filter cup 407 are medium-sized impurities (refer to Figure 13 The impurities in the fourth filter cup 507 are small particles (see Figure 13 z31 and z32 in the figure), at this time, the first rotating shaft 208 is driven by the servo motor 101 or the manual rotating wheel 110 to rotate 90 degrees clockwise. When the first rotating shaft 208 rotates, the second rotating shaft 308, the third rotating shaft 408, and the fourth rotating shaft 510 are controlled to rotate 90 degrees clockwise through the chain 606 and the corresponding gears (the first gear 209, the second gear 309, the third gear 409 and the fourth gear 509) (the result after rotation is shown in FIG. Figure 14 ); Step 3: After the second rotating shaft 308, the third rotating shaft 408, and the fourth rotating shaft 510 rotate, the backwash of the filter cups (the first filter cup 207, the second filter cup 307, the third filter cup 407, and the fourth filter cup 507) is triggered. Figure 15 and Figure 16 At this time, the liquid to be filtered enters the first sphere 202 again through the water inlet pipe 206. During this process, the large impurities z11 in the first filter cup 207 and the medium impurities z23 in the liquid to be filtered are filtered out of one end of the second filter cup 307 through the first connecting pipe 601. The medium impurities z21 at the other end of the second filter cup 307 and the small impurities z33 in the liquid to be filtered are discharged through the first impurity outlet pipe 306, and the large impurities z12 in the liquid to be filtered are filtered out of one side of the first filter cup 207. At the same time, the clean liquid enters the fourth sphere 502 through the clean liquid outlet pipe 508, and the small impurities z32 at one end of the fourth filter cup 507 are discharged through the third impurity outlet pipe 511. Step 4: After a set unit time, the servo motor 101 or the manual rotating wheel 110 drives the first rotating shaft 208 to rotate 90 degrees counterclockwise. When the first rotating shaft 208 rotates, the chain 606 and the corresponding gears (the first gear 209, the second gear 309, the third gear 409 and the fourth gear 509) control the second rotating shaft 308, the third rotating shaft 408 and the fourth rotating shaft 510 to rotate 90 degrees counterclockwise (refer to the result after rotation). Figure 17 ); Step 5: Reference Figure 18 and Figure 19 The liquid to be filtered first enters the first sphere 202 through the water inlet pipe 206. After being filtered by the first filter cup 207 (the filtered large particles of impurities z13 are retained in the first filter cup 207), the liquid is divided into two streams and flows through the first connecting pipe 601 and the second connecting pipe 602 to the second ball valve 300 and the third ball valve 400 respectively. One stream of the liquid to be filtered enters the second sphere 302 and is filtered by the second filter cup 307 (the filtered medium particles of impurities z24 are retained in the second filter cup 307). The other stream The liquid to be filtered enters the third sphere 402 and is filtered through the third filter cup 407 (the filtered medium impurity particles z22 and large impurity particles z12 are retained in the third filter cup 407). The two streams of liquid to be filtered then enter the fourth sphere 502, are filtered through the fourth filter cup 507, and the clean liquid is discharged through the clean pipe 508 (small impurity particles z31, small impurity particles z35, and large impurity particles z11 are present at one end of the fourth filter cup 507, and small impurity particles z34 are present at the other end of the fourth filter cup 507). Step 6: After a set unit time, the servo motor 101 or the manual rotating wheel 110 drives the first rotating shaft 208 to rotate 90 degrees counterclockwise. When the first rotating shaft 208 rotates, the chain 606 and the corresponding gears (the first gear 209, the second gear 309, the third gear 409 and the fourth gear 509) control the second rotating shaft 308, the third rotating shaft 408 and the fourth rotating shaft 510 to rotate 90 degrees counterclockwise (refer to the result after rotation). Figure 20 ); Step 7: After the second rotating shaft 308, the third rotating shaft 408, and the fourth rotating shaft 510 have completed their rotation, backwashing of the filter cups (the first filter cup 207, the second filter cup 307, the third filter cup 407, and the fourth filter cup 507) is triggered. Figure 21 and Figure 22At this time, the liquid to be filtered enters the first sphere 202 again through the water inlet pipe 206. During this process, the large impurities z13 on one side of the first filter cup 207 and the medium impurities z26 in the liquid to be filtered are filtered into one end of the third filter cup 407 through the second connecting pipe 602. The medium impurities z21 at the other end of the third filter cup 407 and the small impurities z36 in the liquid to be filtered are discharged through the second impurity outlet pipe 406, and the large impurities z14 in the liquid to be filtered are filtered out of the first filter cup 207. At the same time, the clean liquid enters the fourth sphere 502 through the clean liquid outlet pipe 508, and the small impurities z31, small impurities z35, medium impurities z23, and large impurities z11 at one end of the fourth filter cup 507 are discharged through the third impurity outlet pipe 511. Step 8: After a set unit time, the servo motor 101 or the manual rotating wheel 110 drives the first rotating shaft 208 to rotate 90 degrees clockwise. When the first rotating shaft 208 rotates, the chain 606 and the corresponding gears (the first gear 209, the second gear 309, the third gear 409 and the fourth gear 509) control the second rotating shaft 308, the third rotating shaft 408 and the fourth rotating shaft 510 to rotate 90 degrees clockwise (refer to the result after rotation). Figure 23 ); Step 9: Reference Figure 24 The liquid to be filtered first enters the first sphere 202 through the water inlet pipe 206. After being filtered by the first filter cup 207 (the filtered large particles of impurities z15 are retained in the first filter cup 207), the liquid is divided into two streams and flows through the first connecting pipe 601 and the second connecting pipe 602 to the second ball valve 300 and the third ball valve 400 respectively. One stream of the liquid to be filtered enters the second sphere 302 and is filtered by the second filter cup 307 (the filtered medium particles of impurities z24 are retained in the second filter cup 307). The other stream of the liquid to be filtered enters the second sphere 302 and is filtered by the second filter cup 307 (the filtered medium particles of impurities z24 are retained in the second filter cup 307). The filtered liquid enters the third sphere 402 and is filtered through the third filter cup 407 (the filtered medium particle impurities z25 are retained in the third filter cup 407). Then, the two streams of filtered liquid enter the fourth sphere 502, are filtered through the fourth filter cup 507, and the clean liquid is discharged through the clean pipe 508 (small particle impurities z36, small particle impurities z34, and large particle impurities z13 are stored at one end of the fourth filter cup 507, and small particle impurities z37 are stored at the other end of the fourth filter cup 507). Then, steps 1 to 9 are repeated in a cycle.
