Description

Technical Field

[0001] This invention relates to the field of mechanical equipment, specifically to a multifunctional valve and its usage method. Background Technology

[0002] In the transportation of liquid media, especially water, it is often necessary to filter and regulate the flow of the water. Traditional valves, such as ball valves, do not have dedicated filtration components. Instead, a third-party filtration component is installed in the outlet direction of the same pipeline. When cleaning the filter screen, the valve must be closed first, and then the filtration equipment must be disassembled and the slag removed. This operation is cumbersome, time-consuming, and labor-intensive. In addition, as the service life increases, the internal sealing components of the valve will age, and liquid will inevitably leak into the valve body. There is no centralized drainage system designed for this purpose, and the liquid will further corrode the internal components of the valve body, reducing the service life of the valve. Summary of the Invention

[0003] To address the problems in the prior art, the present invention provides a multifunctional valve and its usage method.

[0005] Specifically, the opening and closing mechanism includes an upper cover and a first housing. The upper cover is sealed at the top of the valve body, and the first housing is sealed at the top of the upper cover. A cylindrical valve core is movably connected inside the valve body. Two connecting grooves are opened inside the valve core. The connecting grooves are used to switch the opening and closing of the inlet pipe, outlet pipe, first pipe and second pipe. A sealing ring is installed on the side wall of the valve core.

[0006] Specifically, the opening and closing mechanism further includes a connecting sleeve. The valve core is fitted with a connecting sleeve at its top end. A sliding plate is slidably connected inside the connecting sleeve. A bushing is fixedly connected to the top end of the sliding plate. The outer diameter of the bushing is smaller than the inner diameter of the connecting sleeve. The bushing is rotatably connected to the top cover and the first housing. The bushing extends to the outside of the top end of the first housing.

[0007] Specifically, the opening and closing mechanism further includes a worm gear. The worm gear is provided inside the first housing and is fixedly connected to the bushing. A worm is rotatably connected inside the first housing. The worm meshes with the worm gear. One end of the worm extends to the outside of the first housing and is fixedly connected to the end of the worm with a first control disc.

[0008] Specifically, the control mechanism includes a lead screw, which is provided inside the bushing. The length of the lead screw is greater than that of the bushing. The top ends of the lead screw and the bushing are threaded together. A second control disc is fixedly connected to the top end of the lead screw, and a valve core is rotatably connected to the bottom end of the lead screw.

[0009] Specifically, the auxiliary mechanism includes a second housing, inside which a spoke-shaped radial wheel is fixedly connected. A sliding plate is provided at the top of the radial wheel, and the sliding plate is slidably connected to the valve body. The sliding plate is located at the bottom of the valve core, and multiple balls are rolled between the sliding plate and the valve core. A first spring abuts between the sliding plate and the radial wheel, and the bottom of the second housing is hemispherical.

[0010] Specifically, the drainage mechanism includes a first collection tank, the valve core has a first collection tank at its top, the valve core has multiple drainage tanks running through its interior, the slide plate has a second collection tank at its top, the slide plate has multiple drainage pipes connected to its bottom end, the drainage pipes are connected to the second collection tank, the drainage pipes and the radial wheel are staggered, the bottom end of the second housing is threaded with a storage pipe, the storage pipe is made of transparent material, and the bottom end of the storage pipe is detachably connected with a plug.

[0011] Specifically, the slag discharge mechanism includes an inclined cylinder. The connecting pipe is provided with an inclined cylinder that is set at an inclination. A semi-open filter screen tube is installed inside the inclined cylinder. The filter screen tube is arranged vertically. A limiting shaft is provided on the semi-open side of the filter screen tube. The limiting shaft is fixedly connected to the inside of the connecting pipe. A baffle is rotatably connected to the limiting shaft. A torsion spring is wound on the limiting shaft. The torsion spring drives the baffle to deflect.

[0012] Specifically, the slag discharge mechanism also includes an end cover. The bottom end of the inclined cylinder is sealed with an end cover, and the bottom outlet of the end cover is sealed with a sealing plug. A limit plug passes through the sealing plug, and a gasket is fitted on the top of the limit plug. A second spring is fitted on the limit plug, and the second spring abuts against the gasket and the inner wall of the end cover. An adjusting nut is threaded to the bottom end of the limit plug, and the adjusting nut limits the sealing plug.

[0013] Specifically, a multi-functional valve and its usage method include the following steps:

[0014] a: When the valve needs to be used, first rotate the first control panel, the worm gear meshes with the worm wheel, and the valve core is driven to rotate to a specified angle through the bushing. Then the liquid enters the interior of the valve body from the inlet pipe, flows out through the first pipe, reaches the second pipe through the connecting pipe, and is finally discharged through the outlet pipe.

[0015] b: When adjusting the flow rate, rotate the second control panel, and drive the valve core to move to the bottom end through the lead screw, so as to accurately adjust the overlap of the connecting groove and each pipe hole groove, thereby achieving the function of flow rate regulation;

[0016] c: Liquid that accidentally overflows into the valve body will be collected in the transparent storage tube under the action of gravity through the water collection of each of the first liquid collection tank and the second liquid collection tank, so that the operator can observe the liquid collection and remove the plug to drain it.

[0017] d: Under normal circumstances, the liquid flows out from the first pipe and then reaches the second pipe through the connecting pipe. The liquid pushes the baffle so that it cannot form an obstruction. The liquid flows through the filter screen tube and the impurities are concentrated inside the inclined cylinder.

[0018] e: During the slag discharge operation, the valve core is rotated 90° by the first control panel, causing the liquid to flow in the reverse direction inside the connecting pipe. At this time, the baffle is reset by the torsion spring and begins to obstruct the liquid flow, thus increasing the liquid pressure. When the pressure is higher than the compression force of the second spring, the sealing plug no longer seals the slag discharge port of the end cap, and the filtered impurities are concentrated and discharged. After the discharge is completed, the valve core is switched back to its previous position, and the flowing liquid continues to be filtered.

[0019] The beneficial effects of this invention are:

[0020] The multifunctional valve and its usage method described in this invention facilitate the adjustment of the valve core's rotation angle through the opening and closing mechanism, thereby regulating the flow direction of liquid within the flow pipe. This, in conjunction with the slag discharge mechanism, enables the cleaning of the filter screen and rapid slag discharge. The auxiliary mechanism provides stable support for the valve core's rotation by leveraging its vertical movement. Furthermore, the drainage mechanism pre-positions a collection tank for any liquid that may overflow into the valve body, reducing the contact gap between the liquid and the components, guiding the liquid to drain quickly, and extending the valve's service life.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1 - Figure 11 As shown, the present invention discloses a multifunctional valve and its usage method, comprising a valve body 1. The valve body 1 has an inlet pipe 2, an outlet pipe 3, a first pipe 4, and a second pipe 5 arranged symmetrically on its outer side. The inlet pipe 2 and outlet pipe 3 are symmetrically arranged, as are the first pipe 4 and the second pipe 5. A connecting pipe 222 is installed between the first pipe 4 and the second pipe 5. The valve body 1 has an opening and closing mechanism 6 inside, and the opening and closing mechanism 6 has a flow control mechanism 7 inside. The bottom end of the opening and closing mechanism 6 has an auxiliary mechanism 8, and the auxiliary mechanism 8 has a drainage mechanism 9 inside. The connecting pipe 222 has a slag discharge mechanism 10 inside.

[0038] Specifically, the opening and closing mechanism 6 includes an upper cover 61 and a first housing 62. The upper cover 61 is sealed to the top of the valve body 1, and the first housing 62 is sealed to the top of the upper cover 61. A cylindrical valve core 63 is movably connected inside the valve body 1. The valve core 63 has two connecting grooves 64 inside, which are used to switch the opening and closing of the inlet pipe 2, the outlet pipe 3, the first pipe 4, and the second pipe 5. A sealing ring 692 is installed on the side wall of the valve core 63. A connecting sleeve 65 is installed at the top of the valve core 63, and a sliding plate 67 is slidably connected inside the connecting sleeve 65. A bushing 66 is fixedly connected to the top of the sliding plate 67. The outer diameter of the bushing 66 is smaller than the inner diameter of the connecting sleeve 65. The bushing 66 is rotatably connected to the upper cover 61 and the first housing 62, and extends to the outside of the top of the first housing 62. A worm gear 68 is provided inside the first housing 62. The worm gear 68 is fixedly connected to the bushing 66. A worm 69 is rotatably connected inside the first housing 62. The worm 69 meshes with the worm gear 68. One end of the worm 69 extends to the outside of the first housing 62 and the end is fixedly connected to the first control disc 691. Initially, the valve core 63 is as follows: Figure 5 As shown in Figure 2, when it is necessary to change the flow direction of the liquid inside the connecting pipe 222, simply rotate the first control disc 691. The worm gear 69 engages with the worm wheel 68 to rotate, and then the action of the bushing 66 drives the connecting sleeve 65 to rotate accordingly. The valve core 63 then rotates to a suitable angle along with the connecting sleeve 65. The changed valve core 63 is as follows: Figure 5As shown in Figure 3, the liquid flows in the opposite direction, achieving a rapid change in liquid flow direction. When flow throttling is required, simply change the valve core 63 to the desired position. Figure 5 As shown in Figure 1, the flow channel 65 and each pipe no longer overlap and are connected, thus achieving a double-closed flow interception function.

[0039] Specifically, the flow control mechanism 7 includes a lead screw 71, which is located inside the bushing 66. The length of the lead screw 71 is greater than that of the bushing 66. The top ends of the lead screw 71 and the bushing 66 are threaded together. A second control disc 72 is fixedly connected to the top end of the lead screw 71, and a valve core 63 is rotatably connected to the bottom end of the lead screw 71. When it is necessary to change the flow rate, such as... Figure 6 As shown, simply rotating the second control panel 72 drives the lead screw 71 to rotate. The lead screw 71 is threadedly connected to the top end of the bushing 66, while the bottom end of the lead screw 71 is rotatably connected to the valve core 63. When the lead screw 71 moves radially, the valve core 63 drives the connecting sleeve 65. The connecting sleeve 65 moves towards the bottom end in conjunction with the sliding plate 67. At this time, the overlap between the connecting groove 64 and the slots of each pipeline decreases linearly, which is more conducive to precise flow control. Thus, the valve can be used in applications with higher requirements.

[0040] Specifically, the auxiliary mechanism 8 includes a second housing 81, inside which a spoke-shaped radial wheel 82 is fixedly connected. A sliding plate 84 is provided at the top of the radial wheel 82, and the sliding plate 84 is slidably connected to the valve body 1. The sliding plate 84 is located at the bottom end of the valve core 63. Multiple balls 85 are rolled between the sliding plate 84 and the valve core 63. A first spring 83 abuts against the sliding plate 84 and the radial wheel 82. The bottom end of the second housing 81 is hemispherical. Figure 8 As shown, the second housing 81 is provided with the radial wheel 82 inside. The radial wheel 82 supports the slide plate 84 through the first spring 83, so that the slide plate 84 provides a reset support for the valve core 63, helping to reduce the resistance to its up and down movement. A plurality of balls 85 are provided between the valve core 63 and the slide plate 84, thereby greatly reducing the resistance between the valve core 63 and the slide plate 84, further reducing the resistance to its rotation, and thus assisting the valve core 63 to move more flexibly inside the valve body 1 and operate more easily.

[0041] Specifically, the drainage mechanism 9 includes a first collection groove 91, the top of the valve core 63 has a first collection groove 91, the valve core 63 has multiple drainage grooves 92 running through its interior, the top of the sliding plate 84 has a second collection groove 93, the bottom of the sliding plate 84 is connected to multiple drainage pipes 94, the drainage pipes 94 communicate with the second collection groove 93, the drainage pipes 94 and the radial wheel 82 are staggered, the bottom of the second housing 81 is threadedly connected to a storage pipe 95, the storage pipe 95 is made of transparent material, and the bottom of the storage pipe 95 is detachably connected to a stopper 96; Figure 8 As shown, the top of the valve core 63 is provided with a first liquid collection tank 91 for collecting overflowing liquid. The top of the slide plate 84 is also provided with a similar second liquid collection tank 93. Under the action of gravity, the liquid drips from the drain tank 92 into the interior of the second liquid collection tank 93, and then is discharged from the drain pipe 94 to the bottom of the second housing 81 for collection. The drain pipe 94 is provided with a rated length to extend and correct the liquid flow path. The drain pipe 94 and the radial wheel 82 are staggered to prevent liquid from dripping onto the radial wheel 82. Finally, the liquid is collected in the storage pipe 95. The storage pipe 95 is made of transparent material so that people can clearly see whether there is water accumulation and to judge whether the valve sealing status is good. Finally, the plug 96 is removed to drain the liquid.

[0042] Specifically, the slag discharge mechanism 10 includes an inclined cylinder 101. The inclined cylinder 101 is installed on the connecting pipe 222 at an incline. A semi-open filter screen tube 102 is installed inside the inclined cylinder 101. The filter screen tube 102 is vertically continuous. A limiting shaft 103 is provided on the semi-open side of the filter screen tube 102. The limiting shaft 103 is fixedly connected to the inside of the connecting pipe 222. A baffle 104 is rotatably connected to the limiting shaft 103. A torsion spring 105 is wound around the limiting shaft 103. The torsion spring 105 drives the baffle 104. 4. Deflection; An end cap 106 is sealed at the bottom of the inclined cylinder 101. A sealing plug 109 is sealed at the bottom outlet of the end cap 106. A limit bolt 108 passes through the sealing plug 109. A gasket 107 is fitted on the top of the limit bolt 108. A second spring 111 is fitted on the limit bolt 108. The second spring 111 abuts against the gasket 107 and the inner wall of the end cap 106. An adjusting nut 110 is threaded to the bottom of the limit bolt 108. The adjusting nut 110 limits the sealing plug 109. Figure 9 , 10As shown in Figure 11, when the liquid flows normally in reverse inside the connecting pipe 222, the water pressure drives the baffle 104 to deflect parallel to the connecting pipe 222. The liquid passes through the filter screen 102, trapping impurities, which are then stored inside the inclined cylinder 101. When there are many impurities, the valve core 63 deflects, causing the liquid to flow in reverse. At this time, the torsion spring 105 resets, driving the baffle 104 to stand vertically, thus causing the water pressure to suddenly increase. When the water pressure exceeds the compression force of the second spring 111, the sealing plug 109 is pushed open, and the liquid carries the impurities out, achieving the function of cleaning the impurities. Afterwards, changing the direction of the valve core 63 switches back to the previous normal filtration. Rotating the adjusting nut 110 presets the compression force of the second spring 111, adjusting the balance between water pressure and slag discharge. Depending on the usage scenario, a control motor can be added to the worm gear 69 and the lead screw 71 for remote driving to adjust the flow rate and automatically discharge slag.

[0043] Specifically, a multi-functional valve and its usage method include the following steps:

[0044] a: When the valve needs to be used, first rotate the first control disc 691, and the worm gear 69 meshes with the worm wheel 68, and the valve core 63 is driven to rotate to the specified angle through the bushing 66. Then the liquid enters the interior of the valve body 1 from the inlet pipe 2, flows out through the first pipe 4, reaches the second pipe 5 through the connecting pipe 222, and is finally discharged through the outlet pipe 3.

[0045] b: When adjusting the flow rate, rotate the second control panel 72, and drive the valve core 63 to move to the bottom end through the lead screw 71, so as to accurately adjust the overlap of the connecting groove 64 and each pipe hole groove, thereby achieving the function of flow rate regulation;

[0046] c: Liquid that accidentally overflows into the valve body 1 is collected by gravity through the first liquid collection tank 91 and the second liquid collection tank 93, and finally stored in the transparent liquid storage tube 95, so that the operator can observe the liquid collection and remove the plug 96 to drain it.

[0047] d: Under normal circumstances, the liquid flows out from the first pipe 4 and then reaches the second pipe 5 through the connecting pipe 222. The liquid pushes the baffle 104 so that it cannot form an obstruction. The liquid flows through the filter screen pipe 102 and the impurities filtered out are concentrated inside the inclined cylinder 101.

[0048] e: During the slag discharge operation, the valve core 63 is rotated 90° by the first control panel 691, causing the liquid to flow in the reverse direction inside the connecting pipe 222. At this time, the baffle 104 is reset by the torsion spring 105 and begins to obstruct the liquid flow, thus increasing the liquid pressure. When the pressure is higher than the compression force of the second spring 111, the sealing plug 109 no longer seals the slag discharge port of the end cover 106, and the filtered impurities are concentrated and discharged. After the discharge is completed, the valve core 63 is switched back to its previous position, and the flowing liquid continues to be filtered.

[0049] In use, the valve core 63 initially... Figure 5 As shown in Figure 2, when it is necessary to change the flow direction of the liquid inside the connecting pipe 222, simply rotate the first control disc 691. This causes the worm gear 69 to mesh with the worm wheel 68, rotating it. The movement of the bushing 66 then drives the connecting sleeve 65 to rotate accordingly. The valve core 63 then rotates to the appropriate angle along with the connecting sleeve 65. The changed valve core 63 appears as shown in Figure 2. Figure 5 As shown in Figure 3, the liquid flows in the opposite direction, achieving a rapid change in liquid flow direction. When flow throttling is required, simply change valve core 63 to the desired position. Figure 5 As shown in Figure 1, the flow channel 65 and the various pipes no longer overlap and are interconnected, thus achieving a double-closed flow interception function; when it is necessary to change the flow rate, such as Figure 6 As shown, simply rotating the second control panel 72 drives the lead screw 71 to rotate. The top end of the lead screw 71 is threadedly connected to the bushing 66, while the bottom end of the lead screw 71 is rotatably connected to the valve core 63. When the lead screw 71 moves radially, the valve core 63 drives the connecting sleeve 65. The connecting sleeve 65 moves towards the bottom end in conjunction with the sliding plate 67. At this time, the overlap between the connecting groove 64 and the slots of each pipeline decreases linearly, which is more conducive to precise control of the flow direction. Thus, the valve can be used in applications with higher requirements. Figure 8 As shown, the second housing 81 has a radial wheel 82 inside. The radial wheel 82 supports the slide plate 84 through the first spring 83, so that the slide plate 84 provides a reset support for the valve core 63, helping to reduce the resistance to its up and down movement. Multiple balls 85 are arranged between the valve core 63 and the slide plate 84, which greatly reduces the resistance between the valve core 63 and the slide plate 84, further reducing the resistance to its rotation, thereby assisting the valve core 63 to move more flexibly inside the valve body 1 and making the operation easier; Figure 8As shown, the top of the valve core 63 is provided with a first liquid collection tank 91 for collecting overflowing liquid. The top of the sliding plate 84 is also provided with a similar second liquid collection tank 93. Under the action of gravity, the liquid drips from the drain tank 92 into the interior of the second liquid collection tank 93, and then is discharged through the drain pipe 94 to the bottom of the second housing 81 for collection. The drain pipe 94 has a rated length to extend and correct the liquid flow path. The drain pipe 94 and the radial wheel 82 are staggered to prevent liquid from dripping onto the radial wheel 82. Finally, the liquid is collected in the storage pipe 95, which is made of transparent material, allowing for easy observation of any water accumulation and serving to determine the valve's sealing condition. Finally, the plug 96 is removed to drain the liquid. Figure 9 , 10 As shown in Figure 11, when the liquid flows normally in reverse inside the connecting pipe 222, the water pressure drives the baffle 104 to deflect parallel to the connecting pipe 222. The liquid passes through the filter screen 102, trapping impurities, which are then stored inside the inclined cylinder 101. When there are many impurities, the deflection valve core 63 causes the liquid to flow in reverse. At this time, the torsion spring 105 resets, driving the baffle 104 to stand vertically, thus causing the water pressure to suddenly increase. When the water pressure exceeds the compression force of the second spring 111, the sealing plug 109 is pushed open, and the liquid carries the impurities out, achieving the function of cleaning the impurities. Afterwards, changing the direction of the valve core 63 will switch back to the previous normal filtration. Rotating the adjusting nut 110 can preset the compression force of the second spring 111, adjusting the balance between water pressure and slag discharge. Depending on the application scenario, a control motor can be added to the worm gear 69 and the lead screw 71 for remote driving to adjust the flow rate and automatically discharge slag.

7. A multifunctional valve and its method of use according to any one of claims 1-6, characterized in that, Includes the following steps: a: When the valve needs to be used, first rotate the first control disc, and through the worm gear meshing with the worm wheel, drive the valve core to rotate to the specified angle through the bushing. Then the liquid enters the interior of the valve body from the inlet pipe, flows out through the first pipe, reaches the second pipe through the connecting pipe, and is finally discharged through the outlet pipe. b: When adjusting the flow rate, rotate the second control panel, and the valve core will move to the bottom end through the lead screw to precisely adjust the overlap of the connecting groove and each pipe hole groove, so as to achieve the function of flow rate regulation; c: Liquid that accidentally overflows into the valve body will be collected in the transparent storage tube under the action of gravity through the water collection of each of the first and second liquid collection tanks, so that the operator can observe the liquid collection and remove the plug to drain it. d: Under normal circumstances, the liquid flows out from the first pipe and then reaches the second pipe through the connecting pipe. The liquid pushes the baffle so that it cannot form an obstruction. The flowing liquid is filtered by the filter screen tube, and the filtered impurities are concentrated inside the inclined cylinder. e: During the slag discharge operation, the valve core is rotated 90° by the first control panel, causing the liquid to flow in the reverse direction inside the connecting pipe. At this time, the baffle is reset by the torsion spring and begins to obstruct the liquid flow, thus increasing the liquid pressure. When the pressure is higher than the compression force of the second spring, the sealing plug no longer seals the slag discharge port of the end cap, and the filtered impurities are concentrated and discharged. After the discharge is completed, the valve core is switched back to its previous position, and the flowing liquid continues to be filtered.
