Description

Technical Field

[0001] This invention belongs to the technical field of liquid-gas tight connection elements, specifically relating to a fluid connector with adjustable flow rate and its processing equipment. Background Technology

[0002] Fluid connectors, also known as fluid fittings, are devices used to connect pipes that transport fluids. There are many types and varieties of fluid connectors. During fluid transport, it is necessary to control the flow rate or filter impurities, and different types of fluid connectors can achieve different functions.

[0003] Currently, the filter mechanism in common fluid connectors is located in the flow path of the connector. After prolonged use, the filter mesh is easily clogged by impurities and needs to be removed from the connector for cleaning, which requires stopping the flow. In some special applications, stopping the flow is not permitted; that is, the filter mechanism in the fluid connector must be cleaned while the fluid is flowing. Current fluid connectors do not have this capability. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable flow rate fluid connector and its processing equipment in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] An adjustable flow rate fluid connector and its processing equipment include a ball valve body, an L-shaped inlet channel and an L-shaped outlet channel disposed within the ball valve body, a horizontal through groove disposed at the junction of the L-shaped inlet channel and the L-shaped outlet channel, an upper through groove and a lower through groove disposed at the upper and lower ends of the ball valve body respectively, a flow rate regulating component disposed at the upper through groove, and a filter mechanism connected to the lower through groove. The upper through groove and the lower through groove are respectively connected to the L-shaped outlet channel and the L-shaped inlet channel.

[0007] The fluid flow path within the fluid connector is as follows: it flows in from the L-shaped inlet channel of the ball valve body, passes through the filter screen, flows into the L-shaped outlet channel from the horizontal groove, and then flows into the next section of the pipeline from the L-shaped outlet channel.

[0008] The flow rate adjustment component includes a linear moving component and a blocking component connected to one end of the linear moving component. The linear moving component is used to adjust the distance between the blocking component and the horizontal channel.

[0009] The filtration mechanism includes a detachable bottom insert connector connected to the lower through slot, a filter screen cylinder connected to the bottom insert connector, an auxiliary track assembly, and a cleaning mechanism. The filter screen cylinder covers the horizontal through slot and is used to filter liquid flowing through the horizontal through slot from the L-shaped liquid inlet channel. The auxiliary track assembly and the cleaning mechanism are both located inside the filter screen cylinder.

[0010] The cleaning mechanism includes a driven circular motion component, a cleaning component connected to one end of the driven circular motion component, and a reset component connected to the cleaning component. The driven circular motion component is connected to the sealing component, and the cleaning component is in contact with the auxiliary track component. The driven circular motion component is used to drive the cleaning component to perform circular motion around the central axis of the filter cylinder. The auxiliary track component is used to adjust the distance between the cleaning component and the filter cylinder. The reset component is used to control the cleaning component to always be in contact with the auxiliary track component.

[0011] When the linear motion component drives the sealing component to move toward the horizontal through groove, the sealing component can drive the driven circular motion component connected to it to rotate, and drive the cleaning component connected to it to rotate in the same direction and at the same angle. As the cleaning component rotates with the driven circular motion component, it is limited by the auxiliary track component. When it passes through the corresponding mesh holes on the filter screen, it can first move toward the mesh holes and gradually insert into the mesh holes to clean the mesh holes, and then reset and disengage from the mesh holes. During this process, the cleaning component continues to rotate with the driven circular motion component.

[0012] As a further optimization of the present invention, the linear movement component includes a limiting sleeve connected to the inner wall of the upper through groove, a sealing washer connected to the upper end of the limiting sleeve, a sealing sleeve detachably connected to the opening of the upper through groove, an adjusting screw movably connected to the center of the sealing sleeve, a handle connected to one end of the adjusting screw, and a sliding member disposed in the limiting sleeve, wherein the sliding member is threadedly connected to the other end of the adjusting screw.

[0013] The specific adjustment process of the linear movement component is as follows: the adjusting handle drives the adjusting screw to rotate. After the adjusting screw rotates, the sliding part is driven to move along the limiting sleeve towards the horizontal through groove through the threaded engagement. The sliding part and the limiting sleeve are in close contact, and the fluid cannot flow into the upper through groove from between the sliding part and the limiting sleeve. The sealing gasket and sealing sleeve are used to tightly seal the upper opening of the upper through groove.

[0014] As a further optimization of the present invention, the sliding member includes a square rod and a round rod connected to the lower end of the square rod. Both the square rod and the round rod are provided with screw holes that cooperate with the adjusting screw. The square rod is located in the limiting sleeve. The round rod passes through the horizontal through groove and is detachably connected to the driven circumferential motion component. The outer wall of the round rod is provided with a first external thread.

[0015] When the adjusting screw rotates, the sliding component uses a threaded connection to drive the square rod in the sliding part to move along the limiting sleeve toward the horizontal through groove. When the square rod moves, it drives the round rod connected to it to move in the same direction and at the same distance. During the movement, the square rod will not rotate with the adjustment screw because it is limited by the limiting sleeve. It can only move along the axial direction of the adjusting screw, or toward the horizontal through groove, or toward the handle.

[0016] As a further optimization of the present invention, the sealing assembly includes an elastic sealing element connected to the outer wall of the round rod, and the elastic sealing element is matched with the horizontal through groove.

[0017] The elastic sealing element can deform and completely seal the horizontal through groove when it is inserted into it. When the distance between the elastic sealing element and the horizontal through groove changes, the fluid velocity at the horizontal through groove will also change accordingly.

[0018] As a further optimization of the present invention, the driven circular motion component includes a groove located at the middle of the bottom insert connector, a rotating shaft movably connected to the inner wall of the groove, a rotating cylinder connected to the upper end of the rotating shaft, a connecting rod connected to the outer wall of the rotating cylinder, and a limiting plate connected to one end of the connecting rod. The inner wall of the rotating cylinder is provided with an internal thread that mates with the first external thread.

[0019] The specific operation process of the driven circular motion component is as follows: because the rotating drum and the rotating shaft are connected, and the rotating shaft and the ground plug connector are movably connected, their positions cannot be moved. Therefore, when the round rod is moving, the rotating drum can make a circular motion around the central axis of the round rod through the threaded engagement. After the rotating drum makes a circular motion, it drives the connecting rod connected to its outer wall and the limiting plate to rotate in the same direction and at the same angle. After the limiting plate makes a circular motion, it can drive the hole cleaning component connected to it to make a circular motion together.

[0020] As a further optimization of the present invention, the lower end of the limiting plate is connected to an arc-shaped slider, and the upper end of the bottom insert connector is provided with an annular groove that matches the arc-shaped slider.

[0021] The arc-shaped slider can move in the same direction and angle as the limiting plate, that is, it moves along the annular groove, which makes the limiting plate more stable during the movement.

[0022] As a further optimization of the present invention, the cleaning assembly includes a movable plate, a plurality of cleaning rods movably connected to the movable plate, and a brush body connected to one end of the cleaning rod. The other end of the cleaning rod passes through a limiting plate, and a second external thread is provided on the outer wall of the cleaning rod. The limiting plate is provided with a screw hole that mates with the second external thread. The plurality of cleaning rods are matched with the mesh holes on the filter cylinder. A limiting ring is provided at the junction of the cleaning rod and the movable plate, and the movable plate and the limiting plate are arranged parallel to each other.

[0023] When the cleaning assembly rotates with the limiting plate, the moving plate, under the limiting action of the auxiliary track assembly, moves towards the mesh on the filter cylinder and drives the cleaning rod connected to it to gradually insert into the mesh. The brush on the cleaning rod can clean the mesh and then return to its original position and detach from the mesh. During the process of the moving plate driving the cleaning rod to move, the second external thread on the cleaning rod and the screw hole on the limiting plate cooperate, so that the cleaning rod continuously rotates during the insertion of the mesh.

[0024] As a further optimization of the present invention, the reset assembly includes a fixed sleeve connected to one side wall of the movable plate, a spring connected to the inner wall of the fixed sleeve, and a movable rod connected to one end of the spring. One end of the movable rod extends to the outside of the fixed sleeve and is slidably connected to the filter cylinder.

[0025] As the moving plate moves along the surface of the auxiliary track assembly, it continuously inserts into the mesh. During this insertion process, the fixed sleeve is squeezed and moves toward the filter cylinder, causing the spring to be compressed. When the moving plate moves away from the filter cylinder, the rebound force provided by the spring ensures that the moving plate remains in contact with the surface of the auxiliary track assembly.

[0026] As a further optimization of the present invention, the auxiliary track assembly includes a fixed ring connected to the bottom insert connector and a plurality of wedges connected to the outer circular surface of the fixed ring. The wedges are isosceles triangles, with a first transition arc surface at the apex of the wedge and a second transition arc surface between the base of the wedge and the outer circular surface of the fixed ring. The length of the base of the wedge is equal to the mesh diameter on the filter cylinder. The other sidewall of the moving plate is in contact with the outer circular surface of the fixed ring.

[0027] The wedge and filter cylinder are designed with matching mesh openings. When the moving plate moves from the outer circular surface of the fixed ring to the surface corresponding to one of the waistlines of the wedge, the moving plate gradually detaches from the fixed ring and moves along that surface of the wedge toward the apex. At this time, the distance between the moving plate and the filter cylinder gradually decreases, driving the cleaning rod to move toward the mesh opening. Specifically, it first gradually inserts into the mesh opening from the edge. When the moving plate moves to the apex of the wedge, the cleaning rod is inserted into the mesh opening to its deepest depth. Then it moves along the surface corresponding to the other waistline of the wedge and gradually moves to the outer circular surface of the fixed tube, at which point the cleaning rod detaches from the mesh opening again.

[0028] A processing device for a fluid connector with adjustable flow rate as described above includes an injection molding machine, a polishing machine, a limiting fixture, and a welding machine.

[0029] The beneficial effects of this invention are as follows: This invention adds a driven circular motion component, a cleaning component, an auxiliary track component, and a reset component to the filter mechanism of the fluid connector. The driven circular motion component converts the linear motion of the flow rate regulating component into circular motion and drives the cleaning component to perform circular motion. The auxiliary track component enables the cleaning component, which is performing circular motion, to reciprocate into the mesh of the filter cylinder to perform a thorough cleaning of the mesh of the filter cylinder, preventing the filter cylinder from being blocked and thus preventing the liquid from flowing. The entire cleaning process does not require disassembling the filter mechanism, making it suitable for fluid systems where frequent or even non-stop flow is not possible.

Detailed Implementation

[0038] The present application will now be described in further detail with reference to the accompanying drawings. The specific embodiments described below are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application.

[0039] Example 1

[0040] like Figure 1-3 As shown, an adjustable flow rate fluid connector includes a ball valve body 1, an L-shaped inlet channel 101 and an L-shaped outlet channel 102 disposed within the ball valve body 1, a horizontal through groove 103 disposed at the junction of the L-shaped inlet channel 101 and the L-shaped outlet channel 102, an upper through groove 104 and a lower through groove disposed at the upper and lower ends of the ball valve body 1 respectively, a flow rate regulating component disposed at the upper through groove 104, and a filter mechanism 2 connected to the lower through groove. The upper through groove 104 and the lower through groove are respectively connected to the L-shaped outlet channel 102 and the L-shaped inlet channel 101.

[0041] The flow rate adjustment component includes a linear motion component and a blocking component connected to one end of the linear motion component. The linear motion component is used to adjust the distance between the blocking component and the horizontal channel 103.

[0042] The filter mechanism 2 includes a bottom insert connector 21 detachably connected to the lower channel, a filter screen cylinder 22 connected to the bottom insert connector 21, an auxiliary track assembly 24, and a cleaning mechanism 23. The filter screen cylinder 22 covers the horizontal channel 103 and is used to filter the liquid flowing from the L-shaped liquid inlet channel 101 through the horizontal channel 103. The auxiliary track assembly 24 and the cleaning mechanism 23 are both located inside the filter screen cylinder 22.

[0043] The hole cleaning mechanism 23 includes a driven circular motion component, a hole cleaning component connected to one end of the driven circular motion component, and a reset component connected to the hole cleaning component. The driven circular motion component is connected to the sealing component, and the hole cleaning component is in contact with the auxiliary track component 24. The driven circular motion component is used to drive the hole cleaning component to make circular motion around the central axis of the filter cylinder 22. The auxiliary track component 24 is used to adjust the distance between the hole cleaning component and the filter cylinder 22. The reset component is used to control the hole cleaning component to always be in contact with the auxiliary track component 24.

[0044] It should be noted that after the fluid connector is connected to the pipeline, the fluid flows in from the L-shaped inlet channel 101 of the ball valve body 1, flows through the filter screen cylinder 22, and then flows into the L-shaped outlet channel 102 from the horizontal channel 103, and then flows into the next section of the pipeline from the L-shaped outlet channel 102. After long-term use, impurities in the liquid can easily clog the filter screen holes of the filter screen cylinder 22, affecting the flow rate of the liquid. At this time, the linear movement component in the flow rate adjustment component can drive the sealing component to move towards the horizontal channel 103. During the movement of the sealing component, the driven circular motion component connected to it is driven to rotate, and the cleaning component connected to it is driven to rotate. The cleaning assembly rotates in the same direction and at the same angle. As it follows the driven circular motion assembly, it is guided by the auxiliary track assembly 24. When passing through the mesh openings on the filter cylinder 22, it first moves towards the mesh openings and gradually inserts itself to clean them. Then it resets and disengages from the mesh openings, continuing its circular motion with the driven circular motion assembly to the next set of mesh openings to be cleaned. This process thoroughly cleans all the mesh openings of the filter cylinder 22, preventing blockages that could impede liquid flow. The entire cleaning process does not require disassembling the filter mechanism, making it suitable for fluid systems where frequent flow interruptions are not possible. The filter mechanism can also be disassembled.

[0045] Among them, such as Figure 2 As shown, the linear motion assembly includes a limiting sleeve 105 connected to the inner wall of the upper through groove 104, a sealing washer 106 connected to the upper end of the limiting sleeve 105, a sealing sleeve 107 detachably connected to the opening of the upper through groove 104, an adjusting screw 108 movably connected to the center of the sealing sleeve 107, a handle 109 connected to one end of the adjusting screw 108, and a sliding member 110 provided in the limiting sleeve 105. The sliding member 110 is threadedly connected to the other end of the adjusting screw 108.

[0046] The sliding member 110 includes a square rod and a round rod connected to the lower end of the square rod. Both the square rod and the round rod are provided with screw holes that cooperate with the adjusting screw 108. The square rod is located in the limiting sleeve 105. The round rod passes through the horizontal through groove 103 and is detachably connected to the driven circumferential motion component. The outer wall of the round rod is provided with a first external thread.

[0047] The sealing assembly includes an elastic sealing element 111 connected to the outer wall of the round rod, and the elastic sealing element 111 is matched with the horizontal through groove 103.

[0048] It should be noted that when adjusting the distance between the sealing component and the horizontal channel 103, the adjusting screw 108 is driven to rotate by the adjusting handle 109. After the adjusting screw 108 rotates, the square rod of the sliding member 110 is driven to move along the limiting cylinder toward the horizontal channel 103 through the threaded engagement. When the square rod moves, it drives the round rod connected to it to move in the same direction and at the same distance. At this time, the elastic sealing member 111 connected to the round rod gradually approaches the horizontal channel 103. The elastic sealing member 111 can be completely inserted into the horizontal channel 103. At this time, the horizontal channel 103 is completely blocked, and the liquid cannot flow. The liquid flow rate at the horizontal channel 103 can be adjusted by the positional relationship between the elastic sealing member 111 and the horizontal channel 103.

[0049] like Figure 2-7 As shown, the driven circular motion component includes a groove 2101 located in the middle of the bottom insert connector 21, a rotating shaft 2301 movably connected to the inner wall of the groove 2101, a rotating cylinder 2302 connected to the upper end of the rotating shaft 2301, a connecting rod 2303 connected to the outer wall of the rotating cylinder 2302, and a limiting plate 2304 connected to one end of the connecting rod 2303. The inner wall of the rotating cylinder 2302 is provided with an internal thread that mates with the first external thread.

[0050] The lower end of the limiting plate 2304 is connected to an arc-shaped slider 2305, and the upper end of the bottom insert connector 21 is provided with an annular groove 2102 that matches the arc-shaped slider 2305.

[0051] It should be noted that when the sealing component moves toward or away from the horizontal through groove 103 by adjusting the linear movement component, the round rod in the linear movement component remains threadedly connected to the rotating cylinder 2302 in the driven circular motion component. The rotating cylinder 2302 is connected to the rotating shaft 2301 and its position cannot be moved. Therefore, when the round rod moves, the rotating cylinder 2302 can make circular motion around the central axis of the round rod through the threaded engagement. After the rotating cylinder 2302 makes circular motion, it drives the connecting rod 2303 and the limiting plate 2304 connected to its outer wall to rotate in the same direction and at the same angle. After the limiting plate 2304 makes circular motion, it can drive the cleaning component connected to it to make circular motion together.

[0052] The cleaning assembly includes a movable plate 2307, several cleaning rods 2306 movably connected to the movable plate 2307, and a brush body 2310 connected to one end of the cleaning rods 2306. The other end of the cleaning rods 2306 passes through a limiting plate 2304, and the outer wall of the cleaning rods 2306 is provided with a second external thread. The limiting plate 2304 is provided with a screw hole that mates with the second external thread. The several cleaning rods 2306 are matched with the mesh holes on the filter cylinder 22. A limiting ring is provided at the junction of the cleaning rods 2306 and the movable plate 2307, and the movable plate 2307 and the limiting plate 2304 are arranged parallel to each other.

[0053] It should be noted that when the cleaning assembly rotates with the limiting plate 2304, the moving plate 2307, under the limiting action of the auxiliary track assembly 24, moves towards the mesh hole on the filter cylinder 22 and drives the cleaning rod 2306 connected to it to gradually insert into the mesh hole. The brush body 2310 on the cleaning rod 2306 can clean the mesh hole and then reset and disengage from the mesh hole. Moreover, during the process of the moving plate 2307 driving the cleaning rod 2306 to move, the second external thread on the cleaning rod 2306 and the screw hole on the limiting plate 2304 cooperate, which allows the cleaning rod 2306 to continuously rotate during the insertion of the mesh hole, so that the brush body 2310 can more thoroughly clean the inner wall of the mesh hole and remove the impurities adhering to the inner wall of the mesh hole.

[0054] The reset assembly includes a fixed sleeve 2308 connected to one side wall of the movable plate 2307, a spring 2311 connected to the inner wall of the fixed sleeve 2308, and a movable rod 2309 connected to one end of the spring 2311. One end of the movable rod 2309 extends to the outside of the fixed sleeve 2308 and is slidably connected to the filter cylinder 22.

[0055] It should be noted that, in order to ensure that the moving plate 2307 remains in contact with the auxiliary track assembly 24 during its circular motion along with the limiting plate 2304, the spring 2311 in the reset assembly provides a pushing force towards the auxiliary track assembly 24 to the moving plate 2307. As the moving plate 2307 moves along the surface of the auxiliary track assembly 24, it continuously inserts into the mesh. During this insertion process, the fixing sleeve 2308 is compressed and moves towards the filter cylinder 22, causing the spring 2311 to be compressed. When the moving plate 2307 moves away from the filter cylinder 22, the rebound force provided by the spring 2311 ensures that the moving plate 2307 remains in contact with the surface of the auxiliary track assembly 24, thereby achieving the effect of the cleaning rod 2306 cleaning the mesh as described above.

[0056] The auxiliary track assembly 24 includes a fixed ring 2401 connected to the bottom insert connector 21 and several wedges 2402 connected to the outer circular surface of the fixed ring 2401. The wedges 2402 are isosceles triangles with a first transition arc surface at the apex and a second transition arc surface between the base of the wedges 2402 and the outer circular surface of the fixed ring 2401. The length of the base of the wedges 2402 is equal to the mesh diameter on the filter cylinder 22. The other side wall of the moving plate 2307 is in contact with the outer circular surface of the fixed ring 2401.

[0057] It should be noted that, as described above, the principle by which the movable plate 2307, driven by the auxiliary track assembly 24, continuously reciprocates between the track auxiliary assembly and the filter cylinder during its circumferential movement following the limiting plate 2304 is as follows: Due to the elastic force of the spring 2311, the movable plate 2307 remains in contact with the outer circular surface of the fixed ring 2401 and the corresponding surface on the wedge 2402 during its circumferential movement following the limiting plate 2304. The mesh openings on the wedge 2402 and the filter cylinder 22 are matched. When the movable plate 2307 moves from the outer circular surface of the fixed ring 2401 to the surface corresponding to a waistline of the wedge 2402, the movable plate 2307 gradually disengages from the fixed ring 2401 and moves along that surface of the wedge 2402 towards the apex. At this time, the movable plate 2307 and the filter cylinder 22 are in contact. The distance between the two gradually decreases, causing the cleaning rod 2306 to move towards the mesh. Specifically, it first gradually inserts into the mesh from the edge. When the moving plate 2307 moves to the top corner of the wedge 2402, the cleaning rod 2306 reaches its deepest insertion depth into the mesh. Then, it moves along the surface corresponding to the other waistline of the wedge 2402 and gradually moves to the outer circumference of the fixed tube. The cleaning rod 2306 then detaches from the mesh again. The whole process is a parabolic reciprocating motion. Combined with the rotation process of the cleaning rod as described above, the cleaning of the mesh is achieved, which is quite convenient.
