Description

Technical Field

[0001] The present invention relates to the technical field of valve bodies, and more particularly to an intelligent water-saving valve. Background Art

[0002] A water-saving valve is a device for efficiently managing water resources. By precisely controlling the water flow, regulating the flow rate and pressure, it helps to achieve the water-saving goal. With the help of an intelligent control system and a motor, the water-saving valve can achieve intelligent on-off control according to different irrigation needs, thus optimizing the energy-saving irrigation activities. However, when the valve flap inside the valve is closed, it is easy to wear between the valve flap and the inner wall of the valve, resulting in the generation of gaps, which in turn causes water leakage problems and affects the effect of agricultural water-saving irrigation. To solve this problem, a Chinese patent with the publication number CN221569448U proposes an intelligent agricultural water-saving valve. Its design includes a valve body and a sealing device. Through the cooperation of a connecting rod, a gear and a moving rod, the reciprocating transmission of the moving rod is realized. When the valve flap is in the closed state, the sealing ring can effectively block the gap between the valve flap and the valve body, significantly improving the closing sealing performance. This innovative design not only solves the problem of gap water leakage but also improves the overall sealing performance of the valve, providing a more reliable solution for agricultural water-saving irrigation.

[0003] However, this kind of sealing device and the water-saving valve adopt independent electric drive control, which is not only difficult to achieve synchronous operation but also may cause water stop delay, affecting the timeliness and reliability of the equipment operation. In addition, to improve the water quality of the outlet, a filtration system is usually set inside the valve body. However, for a water-saving valve equipped with a filtration system, the replacement process of its filtration system is relatively complex, which not only increases the maintenance difficulty but also may affect the long-term stable operation of the equipment. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an intelligent water-saving valve to solve the problems in the above-mentioned background art, that is, while ensuring the synchronous activation of the valve core protection mechanism during the valve closing process, it is also necessary to take into account the efficient filtration function of the filtration system, and optimize its structural design to achieve convenient replacement, thereby improving the reliability and maintenance efficiency of the equipment.

[0005] The present invention provides the following technical solution: An intelligent water-saving valve, comprising a valve body, the left and right ends of which are respectively and hermetically connected to a water inlet pipe and a drain pipe through flanges; A valve rod assembly is longitudinally assembled in the middle of the valve body. The valve rod assembly is composed of a valve flap, a valve cover sealing seat and a connecting shaft. The valve flap can rotate horizontally in the valve body, and its top passes through the valve cover sealing seat and is coaxially connected to the connecting shaft. The valve cover sealing seat is hermetically fixed on the top of the valve body. An adjusting slider assembly is transversely arranged in the valve cover sealing seat. Transmission assemblies are symmetrically arranged at both ends of the adjusting slider assembly. The left transmission assembly is in transmission cooperation with an auxiliary flow-limiting assembly in the water inlet pipe, and the right transmission assembly is in transmission connection with a filtering assembly in the drain pipe; Through holes for inserting the adjusting slider assembly are formed in the left and right side walls of the valve cover sealing seat. The adjusting slider assembly is composed of a guiding slide rail, a bidirectional guide rod and a hinge joint. The guiding slide rail is inserted into the through hole; The bidirectional guide rod is slidably arranged inside the guiding slide rail, and hinge joints are symmetrically distributed at both ends thereof. A gear coplanar with the through hole is fixedly sleeved on the surface of the connecting shaft, and the gear forms an engagement fit with the rack of the bidirectional guide rod; The transmission assembly includes a swing angle execution arm, a connecting rod compensator and a bearing seat. The swing angle execution arm is rotatably connected to a rotating shaft passing through the center of the bearing seat. Its bottom end hermetically passes through a first water-stop resilient partition layer, and its top end extends outwards through the hinge joint.

[0006] Further, the transverse width of the through hole is designed to be greater than the thickness of the guiding slide rail. Adjustable constraint assemblies are also installed on the left and right side walls of the valve cover sealing seat and located outside the through hole.

[0007] Further, the adjustable constraint assembly is composed of a fixed base, a sliding adjustment block, a guiding screw rod and a locking nut. The fixed base is welded outside the through hole, and a slidable and front-back adjustable sliding adjustment block is slidably connected inside it; The guiding screw rod penetrates through the fixed base and the sliding adjustment block and forms a threaded fit with the locking nut on the rear side wall of the sliding adjustment block; The rear side wall of the fixed base is open-shaped, and the sliding adjustment block and the fixed base jointly form a locking port for the guiding slide rail.

[0008] Further, the middle part of the bidirectional guide rod is a rack, and both ends thereof are integrally formed with socket joints. The outer ends of the socket joints are connected with limit bolts in a plug-and-play manner, and the hinge joints are connected to the surfaces of the limit bolts.

[0009] Further, the auxiliary flow-limiting assembly includes a conical plug, a sliding base and a connecting transition block. The sliding base, the connecting transition block and the conical plug are connected in sequence from left to right. The sliding base is slidably clamped in the chute of the water inlet pipe, and the conical plug is adapted to the conical port of the valve body.

[0010] Further, an arc-shaped opening for the swing angle actuator arm to deflect is provided at the top of the bearing housing, and a first water-stop resilient partition layer is arranged on the bottom wall of the bearing housing. The contact part between the first water-stop resilient partition layer and the swing angle actuator arm is hermetically adhered.

[0011] Further, the inner diameter of the hinge joint is larger than the cross-sectional diameter of the swing angle actuator arm. One end of the connecting rod compensator is rotatably connected to the ball head at the bottom end of the swing angle actuator arm through a rotating shaft, and the other end of the connecting rod compensator is adhered to the sliding base in the auxiliary flow-limiting assembly or the cylinder in the filtering assembly through a resilient block.

[0012] Further, the filtering assembly includes a cylinder and a filter element assembled in the filling groove of the cylinder. The right end of the cylinder is a connecting frame. When the filtering assembly moves to the rightmost area, it is the jitter area of the drain pipe, and a vibration transmission mechanism is arranged at its bottom and extends in.

[0013] Further, when the filtering assembly moves to the leftmost area, it is the component replacement area of the drain pipe, and a quick locking assembly is arranged at its bottom.

[0014] Further, the filter element is composed of a filter plate, a filter pad and a stable ring buckle. A groove is provided on the left side of the filter plate, the filter pad is placed in the groove, and the stable ring buckle is fixed to the front wall of the filter plate by buckling, so as to stably assemble the filter pad in the groove. At the same time, the flange structure extending from the bottom of the filter plate is inserted into the arc-shaped opening at the bottom of the cylinder and is flush with the outer wall of the cylinder.

[0015] The technical effects and advantages of the present invention: By providing an adjustment slider assembly, a transmission assembly and an auxiliary flow-limiting assembly, when the valve is opened, the motor drives the valve flap to rotate counterclockwise through the connecting shaft, increasing the opening degree of the valve body. The connecting shaft synchronously drives the gear to move leftward, so that the bidirectional guide rod slides along the guide rail and is pulled out. The hinge joint pushes the swing angle actuator arm to deflect leftward, and the thrust is transmitted to the sliding base through the connecting rod compensator, so that the auxiliary flow-limiting assembly moves rightward, and the conical plug disengages from the conical opening of the valve body, realizing the linkage seal between the valve flap and the conical plug, reducing the water pressure load and effectively prolonging the service life of the core components.

[0016] By providing an adjustment slider assembly, a transmission assembly and a filtering assembly, it is beneficial for the bidirectional guide rod to move leftward to drive the hinge joint to slide upward along the swing angle actuator arm, so that the swing angle actuator arm deflects leftward around the bearing housing. The connecting rod compensator transmits the swinging traction force, lifts the right end and pulls the filtering assembly to move rightward until the cylinder contacts the vibration transmission mechanism. The vibration force of the vibration transmission rod is transmitted to the cylinder through the resilient block, reducing the risk of blockage of the filter element and maintaining the flow-through capacity.

[0017] The present invention is provided with a filtering assembly and a quick locking assembly, which is beneficial for closing the valve. When the valve is closed, the shape of the transmission assembly changes and drives the filtering assembly to perform corresponding actions, pushing the filtering assembly to the replacement part area above the quick locking assembly; pulling out the safety limit pin to disengage the plug-type locking rod from the rotating chuck, rotating the rotating chuck to disengage from the bottom opening of the connecting cover, and the filter element falls off from the cylinder groove due to the loss of support of the plug-type locking rod, enabling easy replacement of the filter element and ensuring the continuous operation ability of the water-saving valve.

Detailed implementation manners

[0033] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings in the present invention. In addition, the forms of each structure described in the following embodiments are only examples, and an intelligent water-saving valve related to the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0034] Refer to Figures 1 - 14, the present invention provides an intelligent water-saving valve, which includes a valve body 1, and the left and right ends of the valve body 1 are respectively sealed and connected to a water inlet pipe 2 and a drain pipe 3 through flanges; a valve stem assembly 4 is longitudinally assembled in the middle of the valve body 1. The valve stem assembly 4 is composed of a valve flap 401, a valve cover seal seat 402 and a connecting shaft 403. The valve flap 401 can rotate horizontally in the valve body 1, and its top passes through the valve cover seal seat 402 and is coaxially connected to the connecting shaft 403. The valve cover seal seat 402 is sealed and fixed to the top of the valve body 1; an adjusting slider assembly 5 is horizontally arranged in the valve cover seal seat 402, and transmission assemblies 6 are symmetrically arranged at both ends of the adjusting slider assembly 5. The left transmission assembly 6 is in transmission cooperation with an auxiliary flow-limiting assembly 7 in the water inlet pipe 2, and the right transmission assembly 6 is in transmission connection with a filtering assembly 8 in the drain pipe 3.

[0035] In this embodiment, it should be specifically noted that water flows in from the water inlet pipe 2 end, and the water flow rate is controlled by adjusting the opening between the valve flap 401 and the inner wall of the valve body 1. Finally, the water is transported to the water-using end through the drain pipe 3; Both the water inlet and outlet ends of the valve body 1 are set as conical openings. The conical opening at the water inlet end is used to diffuse the water flow introduced by the water inlet pipe 2 into the inner cavity of the valve body 1, and the conical opening at the water outlet end converges the water flow and then guides it to the drain pipe 3; the conical flared opening at the water inlet end reduces the water flow impact and avoids turbulent flow, and the conical constricted opening at the water outlet end improves the water flow directivity and enhances the transportation efficiency; the two-way conical structure cooperates to form a stable flow state and reduce the pressure loss; A motor is assembled on the top of the valve cover seal seat 402. The motor can be selected as a reversible motor, and its output shaft passes through the valve cover seal seat 402 and forms a coaxial transmission structure with the connecting shaft 403. The control end of the motor is connected to a control system, and a PLC controller can be selected. The start-stop logic control of the motor is realized through a preset program; the control system outputs a PWM signal to adjust the motor speed; the programmable controller realizes the forward and reverse switching function; In this article, all the position relationships about front, back, left and right discussed are defined based on Figures 1 - 2 the perspective presented. These orientation descriptions do not have actual geographical or physical meanings. They are only a reference framework set to help readers more intuitively understand the content in the article. In this way, we can more clearly show the relative position relationships between various parts, so that the whole discussion process becomes easier to understand and follow. Please note that this self-defined orientation identifier is only applicable for internal use in this article and does not represent any absolute direction or position in the real world.

[0036] Refer to Figures 2 - 7, on the left and right side walls of the valve cover sealing seat 402, there are openings for inserting the adjusting slider assembly 5. The adjusting slider assembly 5 is composed of a guiding slide rail 501, a bidirectional guiding rod 502 and a hinge joint 503. The guiding slide rail 501 can be inserted into the opening and is stably fixed by adjusting the size of the locking opening of the adjustable restraint assembly 11; the bidirectional guiding rod 502 is slidably arranged inside the guiding slide rail 501, and hinge joints 503 are symmetrically distributed at its left and right ends; when the hinge joint 503 is slidably sleeved relative to the swing angle actuator arm 601, the swing angle of the swing angle actuator arm 601 can be adjusted by the movement of the hinge joint 503, thereby driving the transmission assembly 6 to change its shape; A gear 404 coplanar with the opening is fixedly sleeved on the surface of the connecting shaft 403, and the gear 404 forms an engaging fit with the rack 5021 of the bidirectional guiding rod 502; the transverse width of the opening is designed to be greater than the thickness of the guiding slide rail 501. On the left and right side walls of the valve cover sealing seat 402, there is also an adjustable restraint assembly 11 located outside the opening. By adjusting the locking range of the adjustable restraint assembly 11, the quick disassembly and assembly of the adjusting slider assembly 5 can be realized, which is convenient for maintenance and replacement when the bidirectional guiding rod 502 is worn due to long-term use.

[0037] In this embodiment, it should be specifically noted that the adjustable restraint assembly 11 is composed of a fixed base 1101, a sliding adjustment block 1102, a guiding screw rod 1103 and a locking nut 1104. Among them, the fixed base 1101 is welded outside the opening, and the sliding adjustment block 1102 that can be adjusted back and forth is slidably connected inside it; the guiding screw rod 1103 penetrates through the fixed base 1101 and the sliding adjustment block 1102 and forms a threaded fit with the locking nut 1104 on the rear side wall of the sliding adjustment block 1102; the rear side wall of the fixed base 1101 is open-shaped, and the sliding adjustment block 1102 and the fixed base 1101 jointly form a locking opening for the guiding slide rail 501. By tightening or loosening the locking nut 1104, the size of the locking opening can be adjusted to realize the fastening or unbinding of the guiding slide rail 501; this structure can accurately adjust the rack 5021 of the bidirectional guiding rod 502 to a position adapted to mesh with the connecting shaft 403 to meet the transmission requirements. In addition, when maintenance is required, the bidirectional guiding rod 502 can be effectively separated from the connecting shaft 403, and the adjusting slider assembly 5 can be taken out without hindrance; The middle part of the bidirectional guiding rod 502 is a rack 5021, and its two ends are integrally formed with the socket 5022. The outer end of the socket 5022 is connected with a limit bolt 5023 in a plug-and-play manner; when it is necessary to disassemble the adjusting slider assembly 5, the limit bolt 5023 and the hinge joint 503 assembled on its surface can be removed first, and then the binding force of the adjustable restraint assembly 11 is unlocked, and the guiding slide rail 501 together with the bidirectional guiding rod 502 inside can be pulled out as a whole; this disassembly process realizes the modular maintenance of the adjusting slider assembly 5, which is convenient for overhauling or replacing internal components; The hinge joint 503 is connected to the surface of the limit bolt 5023; the hinge joint 503 and the limit bolt 5023 can be connected in two ways: fixed socket connection or rotating socket connection. No matter which connection method is adopted, when the bidirectional guide rod 502 moves horizontally, the hinge joint 503 can effectively guide the movement trajectory of the swing angle actuator arm 601, thereby accurately triggering the conversion action of the transmission assembly 6; this design ensures that the mechanism can maintain reliable function realization under different assembly methods.

[0038] Refer to Figures 8 - 9 , Figure 10 and Figure 14 , the transmission assembly 6 includes a swing angle actuator arm 601, a connecting rod compensator 602 and a bearing seat 603. The swing angle actuator arm 601 is rotatably connected to a rotating shaft passing through the center of the bearing seat 603. Its bottom end seals through the first water-stop flexible layer 604, and its top end extends outward and can pass through the hinge joint 503; one end of the connecting rod compensator 602 is rotatably connected to the ball head at the bottom end of the swing angle actuator arm 601 through a rotating shaft, and the other end of the connecting rod compensator 602 is adhered to the sliding base 702 in the auxiliary current-limiting assembly 7 through a flexible block; The auxiliary current-limiting assembly 7 includes a conical plug 701, a sliding base 702 and a connecting transition block 703. The sliding base 702, the connecting transition block 703 and the conical plug 701 are connected in sequence from left to right. The sliding base 702 is slidably clamped in the chute of the water inlet pipe 2, and the conical plug 701 is adapted to the conical opening of the valve body 1.

[0039] In this embodiment, it should be specifically noted that the top of the bearing seat 603 is provided with an arc-shaped opening for the swing angle actuator arm 601 to deflect. The bottom wall of the bearing seat 603 is provided with the first water-stop flexible layer 604, and the contact part between the first water-stop flexible layer 604 and the swing angle actuator arm 601 is sealed and adhered. This design can not only ensure the deflection of the swing angle actuator arm 601 within a limited range, but also effectively block the leakage of the water path; The inner diameter of the hinge joint 503 is designed to be larger than the cross-sectional diameter of the swing angle actuator arm 601 to ensure that when it drives the swing angle actuator arm 601 to move, it can adapt to the angle change of the swing angle actuator arm 601 or the adjustment of the contact point between the hinge joint 503 and the swing angle actuator arm 601; There is a flexible block between the connecting rod compensator 602 and the sliding base 702, so that the connecting rod compensator 602 can transmit the thrust generated at the bottom end when the swing angle actuator arm 601 swings in a circle; during this process, the connecting rod compensator 602 realizes adaptive adjustment and transmits the rightward thrust to the sliding base 702.

[0040] Refer to Figures 10 - 13 , the filter assembly 8 includes a cylinder body 801 and a filter element 802 assembled in the filling groove of the cylinder body 801. The right end of the cylinder body 801 is a connecting frame, and the connecting rod compensator 602 on the right side is connected to the connecting frame of the cylinder body 801 through a flexible block; The filter assembly 8 is moved to the leftmost area, which is the replacement part area of the drain pipe 3. A quick locking assembly 9 is provided at its bottom. The quick locking assembly 9 is composed of a connecting cover 901, a plug-type locking rod 905, a rotating chuck 906, a pivot pin 907 and a safety limit pin 908. Among them, the top opening of the connecting cover 901 is connected to the arc-shaped opening on the bottom wall of the drain pipe 3 by welding; the rotating chuck 906 is rotatably installed at the bottom opening of the connecting cover 901 through the pivot pin 907. The plug-type locking rod 905 can pass through the slot of the rotating chuck 906 and make its top closely fit with the outer wall of the flange of the filter plate 8021. At the same time, the safety limit pin 908 is inserted into the pin holes of the plug-type locking rod 905 and the rotating chuck 906 to realize the limit of the plug-type locking rod 905; The filter assembly 8 is moved to the rightmost area, which is the jitter area of the drain pipe 3. A vibration transmission mechanism 10 that can extend in is provided at its bottom. The vibration transmission mechanism 10 includes a vibration transmission rod 1001, a second water-stop resilient interlayer 1002, a vibration coupling head 1003 and a vibrator housing 1004. Among them, the vibration transmission rod 1001 is sealed through the second water-stop resilient interlayer 1002, and the second water-stop resilient interlayer 1002 is adhesively sealed to the bottom wall of the jitter area. The bottom end of the vibration transmission rod 1001 is fixedly connected to the vibration coupling head 1003. The vibration coupling head 1003 can be connected to the output end of the vibrator. The vibrator is assembled in the vibrator housing 1004, and the vibrator housing 1004 is welded to the outer wall of the drain pipe 3 below the jitter area.

[0041] In this embodiment, it should be specifically noted that the filter element 802 is composed of a filter plate 8021, a filter pad 8022 and a stabilizing ring buckle 8023. Among them, a groove is provided on the left side of the filter plate 8021, the filter pad 8022 is placed in the groove, and the stabilizing ring buckle 8023 is fixed to the front wall of the filter plate 8021 by buckling, so as to stably assemble the filter pad 8022 in the groove; at the same time, the flange structure extending from the bottom of the filter plate 8021 is inserted into the arc-shaped opening at the bottom of the cylinder 801 and is flush with the outer wall of the cylinder 801; In addition, the quick locking assembly 9 may further include a sealing gasket 902, a pull rod 903 and a point push rod 904. Among them, the sealing gasket 902 passes through the side wall of the connecting cover 901 and is sealed and intercepted in its inner cavity. The sealing gasket 902 is connected to the telescopic end of the point push rod 904 through the pull rod 903; when the cylinder 801 moves to the right, if the left port of it exceeds the position of the connecting cover 901, the sealing gasket 902, the pull rod 903 and the point push rod 904 need to be configured to ensure that in the case where the cylinder 801 does not seal the top opening of the connecting cover 901, the sealing gasket 902 acts as a secondary sealing line of defense to avoid the water flow leakage in the drain pipe 3; the actions of the sealing gasket 902 and the plug-type locking rod 905 are implemented successively. The working principle of the present invention: Figures 1 - 12The display diagram shows the structural state of the water-saving valve when it is fully closed. When the valve needs to be opened, the control system starts the motor. The output shaft of the motor drives the valve flap 401 to rotate counterclockwise through the connecting shaft 403, increasing the opening between the valve flap 401 and the valve body 1, thereby increasing the water flow through the valve body 1. At the same time, the connecting shaft 403 drives the gear 404 to rotate, transmitting power to the left to engage with the two-way guide rod 502, causing the two-way guide rod 502 to slide leftward along the inner wall of the guide rail 501 and gradually withdraw. The hinge joint 503 sleeved on the surface of the left end limit bolt 5023 pushes the swing angle actuator arm 601 when moving leftward, and slides downward along the surface of the swing angle actuator arm 601, prompting the swing angle actuator arm 601 to deflect leftward with the rotating shaft passing through the bearing seat 603 as the center. One end of the connecting rod compensator 602 is rotatably connected to the ball head at the bottom end of the swing angle actuator arm 601 through a rotating shaft, and the other end is connected to the center of the sliding base 702 through a resilient block. Therefore, the connecting rod compensator 602 can transmit the thrust generated at the bottom end during the circumferential swing of the swing angle actuator arm 601, and itself shows a downward tilt at the left end, thus making an adaptive adjustment and transmitting the rightward thrust to the sliding base 702, pushing the entire auxiliary flow-limiting assembly 7 to move rightward until the conical plug 701 disengages from the conical opening at the water inlet end of the valve body 1. This process realizes the synchronous operation of opening and closing the valve flap 401 and the conical plug 701, forming a double-sealing mechanism, significantly reducing the water pressure load on the valve flap 401, and effectively extending the service life of the core components. Meanwhile, when the two-way guide rod 502 slides leftward, the hinge joint 503 sleeved on the surface of its right end limit bolt 5023 moves leftward accordingly and slides upward along the surface of the swing angle actuator arm 601, driving the swing angle actuator arm 601 to deflect leftward with the rotating shaft passing through the bearing seat 603 as the center. One end of the connecting rod compensator 602 is rotatably connected to the ball head at the bottom end of the swing angle actuator arm 601 through a rotating shaft, and the other end is connected to the center of the cylinder 801 through a resilient block. Therefore, the connecting rod compensator 602 can transmit the traction force generated at the bottom end during the circumferential swing of the swing angle actuator arm 601, causing its right end to lift, thus completing the adaptive adjustment and transmitting the rightward traction force to the filter element 802, pulling the entire filtration assembly 8 to move rightward until the cylinder 801 contacts the vibration transmission mechanism 10. At this time, the vibration force transmitted by the vibration rod 1001 will continuously act on the filtration assembly 8. Since the connecting rod compensator 602 and the cylinder 801 are connected through a resilient block, the vibration force can conduct the vibration of the cylinder 801, effectively reducing the risk of the filter element 802 being blocked by sludge and ensuring the maintenance of its flow-through capacity. When the valve needs to be closed, the water-saving valve operates in the opposite direction to the opening operation. While gradually sealing the conical orifice with the conical plug 701, it pushes the filter assembly 8 step by step to the replacement area above the quick locking assembly 9. Subsequently, the staff can perform the replacement operation: pull out the safety limit pin 908 so that the plug-type locking rod 905 can be withdrawn from the jack of the rotary chuck 906; rotate the rotary chuck 906 to disengage it from the bottom opening of the connecting cover 901. At this time, the filter element 802 loses the support of the plug-type locking rod 905 and can fall off from the filling groove of the cylinder body 801 and be exported outward through the connecting cover 901. In addition, if the rightward movement distance of the cylinder body 801 during the valve opening stage exceeds the set position of the connecting cover 901, a sealing gasket 902, a pull rod 903 and a point push rod 904 need to be configured to ensure that in the case where the cylinder body 801 does not seal the top opening of the connecting cover 901, the sealing gasket 902 serves as a secondary sealing line of defense to prevent water leakage in the drain pipe 3, which increases the corresponding replacement operation steps. It is necessary to further activate the point push rod 904 so that its telescopic end pulls out the sealing gasket 902 through the pull rod 903 to completely open the channel of the connecting cover 901. After the old parts are discharged, replace the new parts and reset the quick locking assembly 9 to stably install the filter element 802 in the cylinder body 801. The specific operation steps for replacing the filter element 802 are as follows: First, disassemble and separate the stable ring buckle 8023 from the front side of the filter plate 8021, then take out the filter pad 8022 and replace it; then, re-seal the stable ring buckle 8023 to ensure that the filter pad 8022 is firmly attached to the front wall of the filter plate 8021.
