Description

Technical Field

[0001] This invention relates to the field of valve inspection technology, specifically to a valve inspection process and equipment based on multiple sensors. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Leakage or airtightness problems can occur during valve use, which are only discovered during operation and affect performance. Therefore, it is necessary to reduce valve inspection during production to ensure valve quality.

[0003] For example, utility model application CN201822135921.5 discloses a valve inspection device, relating to the field of building equipment. The technical solution includes a base platform. A plug corresponding to the valve to be tested is provided on the side of the sealing mechanism facing the valve to be tested. The beneficial effects of this utility model are: this device is easy to use, unlike the traditional threaded installation method, making the testing process faster. It is applicable to various common utility model tests, and can efficiently and quickly complete valve inspection work on the construction site, avoiding the problem of valve quality affecting the later construction process. Existing valve inspection methods are limited in effectiveness, and during valve inspection, many water stains appear on the valve surface, causing water droplets to fall everywhere when the valve is collected, affecting handling and use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a valve inspection process and equipment based on multiple sensors. Summary of the Invention

[0005] The purpose of this invention is to provide a valve inspection process and equipment based on multiple sensors to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quenching process for pressure rollers to prevent quenching cracks, comprising the following steps:

[0007] S1: Open the auxiliary frame by manually sliding the top cover along the surface of the auxiliary frame. Then, the operator places the valve body to be tested inside the frame. By rotating the inner rod in the middle of the frame clockwise, the pads on the inner rod and the end of the inner rod will move downwards synchronously, thereby limiting and fixing the valve body in the middle of the frame. Then, the second air rod drives the collection plate to move. The movement of the collection plate will drive the connecting plate to move synchronously. The magnetic column on the outer surface of the connecting plate is magnetically attracted and inserted into the hole on one side of the inner plate. Then, the operator inserts the limiting rod from the top of the main body into the bottom frame. Then, the retraction of the second air rod drives the collection plate and the connecting plate to reset. At the same time, the magnetic column separates from the hole in the inner plate.

[0008] S2: By rotating the threaded rod, the operator can simultaneously utilize the sliding limit design between the limit rod and the worktable to facilitate the up-and-down movement of the worktable on the outer surface of the threaded rod. When the operator rotates the worktable, it is positioned in the inspection component area. Then, the oil cylinder drives the limit sleeve to move. The limit sleeve has a sufficiently long conveying pipe inside, so that the moving end of the conveying pipe will be engaged with one end of the valve body. The outer surface of the end of the conveying pipe is provided with a rubber sealing layer to maintain the sealing between the conveying pipe and the valve body during installation. At this time, the valve body valve is closed, and by turning on the air pump, gas is injected into the valve body through the conveying pipe. Then, the air pressure in the valve body is detected by the conveying pipe on one side of the end of the conveying pipe. The change in air pressure is used to determine whether the airtightness of the valve body is good.

[0009] S3: By rotating the threaded rod again, the operator rotates the workbench downward and it is inside the bottom frame. Then, through the design of the fixed plate and the first air rod, the tube in the end plate is moved, so that the tube can be inserted into the end of the valve body. Then, by turning on the water pump, the water inside the bottom frame will be sucked in by the water pump and transported to the inside of the valve body through the tube. The sealing performance of the valve body can be judged by visually observing whether the valve body leaks water when transporting water.

[0010] S4: By opening the valve switch at the valve body, and then threading the liquid flow sensor into the valve body, the water inside the bottom frame will be drawn in by the water pump and transported to the valve body through the pipe by turning on the water pump. The liquid flow sensor can detect the flow rate of the valve body, thus avoiding unevenness on the inner surface of the valve body with good sealing under the same model.

[0011] S5: By rotating the threaded rod in the opposite direction, the worktable on the outer surface of the threaded rod can be moved upward. When it moves to the inspection component area, the air pump can be turned on, and the air blown out by the delivery pipe can be used to remove the water stains on the outer surface of the valve body during inspection. In addition, by pulling the limit rod upward to separate it from the worktable, the worktable will rotate synchronously as the threaded rod is continuously rotated. The continuous rotation of the worktable allows the valve body, which is limited on the outer surface of the worktable, to come into contact with the air blown out by the delivery pipe at multiple angles, which is convenient for cleaning the water stains on the surface of the valve body during the discharge process.

[0012] S6: When the workbench moves to the material chute on one side of the main body, the limit rod is pulled upward to separate it from the workbench. Then, the second air rod drives the collection plate to move. The movement of the collection plate will drive the connecting plate to move synchronously. The magnetic column on the outer surface of the connecting plate is magnetically attracted and inserted into the hole on one side of the inner plate. Then, the second air rod retracts, which will cause the inner plate to stop engaging with the limit rod and achieve separation, making it easy for the user to manually slide the top cover to take out the valve body in the auxiliary frame.

[0013] A valve inspection device based on multiple sensors includes a main body and a top cover. A first protective plate is provided on the front outer surface of the main body, and second protective plates are installed on the left and right outer surfaces of the main body. A material picking groove is opened on the rear side of the main body, and an auxiliary frame is installed on one side of the outer surface of the material picking groove. The top cover is slidably disposed on the top of the auxiliary frame. A material picking component for assisting loading and unloading is provided inside the auxiliary frame. The material picking component includes a second air rod, a collecting plate, a connecting plate, and magnetic columns. The output end of the second air rod is installed with a collecting plate, and a connecting plate is fixedly provided on the outer surface of the collecting plate. Magnetic columns are installed at equal intervals on the outer surface of the connecting plate.

[0014] Furthermore, the top of the main body is provided with a top plate, and the middle of the top plate is provided with an internal plate. Mounting plates are provided on both sides of the top plate by fixing screws, and a top frame is installed on the outer surface of the mounting plate.

[0015] Furthermore, the top outer surface of the top frame is provided with an auxiliary component for limiting the detection piece, and the auxiliary component includes a top frame, a screw and a round shank. The screw is installed in the internal thread of the top frame, and the end of the screw is integrally provided with a round shank.

[0016] Furthermore, a threaded rod is threadedly installed in the middle of the top frame, and a worktable is threadedly provided on the outer surface of the threaded rod. A positioning component for assisting in the placement of the test piece is installed inside the worktable, and four sets of positioning components are provided. A limit rod is slidably installed inside the worktable.

[0017] Furthermore, the positioning component includes a frame, an inner rod, a pad, and an inner plate, with the inner rod threadedly installed in the middle of the frame, a pad provided at the end of the inner rod, and a valve body installed on the outer surface of the pad. A liquid flow sensor is threadedly installed in the middle of the valve body.

[0018] Furthermore, an inspection component for inspecting the test piece is provided on one side of the inner surface of the main body. The inspection component includes a fixed frame, an air pump, a delivery pipe, a limiting sleeve, a pressure sensor, and a hydraulic cylinder. An air pump is provided on one side of the inner surface of the fixed frame, and a delivery pipe is installed at one end of the air pump. A limiting sleeve is provided at the end of the delivery pipe, and a pressure sensor is installed on one side of the outer surface of the delivery pipe. A hydraulic cylinder is provided on one side of the outer surface of the limiting sleeve.

[0019] Furthermore, a bottom frame is provided at the bottom of the main body, and two sets of inspection components are installed on the inner two sides of the bottom frame for performing throughput testing on the test pieces.

[0020] Furthermore, the second inspection component includes a fixed plate, a first air rod, an end plate, a water pump, and a pipe. The first air rod is provided on the outer surface of the fixed plate, the output end of the first air rod is installed with an end plate, and a pipe is engaged inside the end of the end plate. The other end of the pipe is connected to the water pump through a corrugated pipe.

[0021] Furthermore, the bottom frame has a hollow structure inside and is slidably disposed inside the main body.

[0022] This invention provides a valve inspection process and equipment based on multiple sensors, which has the following beneficial effects:

[0023] 1. This valve inspection equipment based on multiple sensors can perform airtightness testing on the valve body transported by the threaded rod through the design of inspection component one. At the same time, after the valve body is inspected, the design of inspection component one can also remove water stains attached to the outer surface of the valve body, making it easier for users to pick up and use the valve body and preventing water stains from dripping everywhere.

[0024] 2. This valve inspection equipment based on multiple sensors can limit the valve body to be inspected through the design of the positioning component, and can automatically load and unload the valve body that is limited by the positioning component through the design of the material picking component, without the need for the user to manually reach into the body to place it, which saves more time.

[0025] 3. This valve inspection equipment based on multiple sensors, through the design of inspection component two, can detect the flow rate of the valve body transported by the threaded rod. The liquid flow sensor can detect the flow rate of the valve body, avoiding unevenness on the inner surface of the valve body under the same model with good sealing, thus ensuring the inspection quality of the valve body. The positioning component and inspection component two are located in the main body, and the vertical rotation of the threaded rod facilitates the sequential quality inspection of the valve body, avoiding omissions in the inspection.

The inner rod 2002 is threaded onto the middle of the frame 2001, and a pad 2003 is provided at the end of the inner rod 2002. A valve body 18 is mounted on the outer surface of the pad 2003, and a liquid flow sensor 19 is threaded onto the middle of the valve body 18. An auxiliary assembly 15 for limiting the position of the test piece is provided on the top outer surface of the top frame 5. The auxiliary assembly 15 includes a top frame 1501, a screw 1502, and a round handle 1. 503, the top frame 1501 has a screw 1502 installed in the internal thread, and the end of the screw 1502 is integrally provided with a round handle 1503. The rear side of the main body 1 is provided with a material picking groove 14, and an auxiliary frame 8 is installed on one side of the outer surface of the material picking groove 14. The top cover 9 is slidably disposed on the top of the auxiliary frame 8. The auxiliary frame 8 is provided with a material picking component 17 for assisting in loading and unloading. The material picking component 17 includes a second air rod 1701, a collection plate 1702, a connecting plate 1703 and a magnetic column 1704. The output end of the second air rod 1701 is installed with the collection plate 1702, and the outer surface of the collection plate 1702 is fixedly provided with the connecting plate 1703. The outer surface of the connecting plate 1703 is equidistantly provided with magnetic columns 1704.

[0035] Please see Figures 1 to 6The inner surface of the main body 1 is provided with an inspection component 13 for inspecting the test piece. The inspection component 13 includes a fixed frame 1301, an air pump 1302, a delivery pipe 1303, a limiting sleeve 1304, a pressure sensor 1305, and a hydraulic cylinder 1306. The air pump 1302 is provided inside the fixed frame 1301, and the delivery pipe 1303 is installed at one end of the air pump 1302. The limiting sleeve 1304 is provided at the end of the delivery pipe 1303, and the pressure sensor 1305 is installed on the outer surface of one side of the delivery pipe 1303. The hydraulic cylinder 1306 is provided on the outer surface of one side of the limiting sleeve 1304. A bottom frame 12 is provided at the bottom inside the main body 1. The bottom frame 12 has two inspection components 16 installed on its inner sides for throughput testing of the test pieces. The bottom frame 12 has a hollow structure and is slidably installed inside the main body 1. There are two sets of inspection components 16. The inspection components 16 include a fixing plate 1601, a first air rod 1602, an end plate 1603, a water pump 1604, and a pipe 1605. The outer surface of the fixing plate 1601 is provided with the first air rod 1602. The output end of the first air rod 1602 is installed with the end plate 1603. The end of the end plate 1603 is fitted with the pipe 1605. The other end of the pipe 1605 is connected to the water pump 1604 through a corrugated pipe.

[0036] The specific operation is as follows: The auxiliary frame 8 is opened by manually sliding the top cover 9 along its surface. The operator then places the valve body 18 to be tested inside the frame 2001. By rotating the inner rod 2002 in the middle of the frame 2001 clockwise, the inner rod 2002 and the pad 2003 on its end surface move downwards synchronously, thus limiting and fixing the valve body 18 in the middle of the frame 2001. Next, the second air rod 1701 drives the collecting plate 1702 to move. The movement of the collecting plate 1702 synchronously drives the connecting plate 1703 to move, and the magnetic post 1704 on the outer surface of the connecting plate 1703 magnetically attracts and inserts into the hole on one side of the inner plate 2004. Then, the operator... The limiting rod 21 is inserted from the top of the main body 1 into the bottom frame 12. Then, the retraction of the second air rod 1701 drives the collection plate 1702 and the connecting plate 1703 to reset, while the magnetic column 1704 separates from the hole in the inner plate 2004. By rotating the threaded rod 10, the limiting rod 21 slides and limits the worktable 11, facilitating the vertical movement of the worktable 11 on the outer surface of the threaded rod 10. When the operator rotates the worktable 11, it is in the inspection component 13 area. Then, the oil cylinder 1306 drives the limiting sleeve 1304 to move. The limiting sleeve 1304 has a sufficiently long conveying pipe 1303 inside, so that the moving end of the conveying pipe 1303 will be engaged with one end of the valve body 18. A rubber sealing layer is provided on the outer surface of the end to maintain the sealing between the delivery pipe 1303 and the valve body 18 during installation. At this time, the valve body 18 is closed, and gas is injected into the valve body 18 through the delivery pipe 1303 by turning on the air pump 1302. Then, the air pressure in the valve body 18 is detected by the delivery pipe 1303 on one side of the end of the delivery pipe 1303. The air pressure change is used to determine whether the airtightness of the valve body 18 is good. By rotating the threaded rod 10 again, the operator rotates the workbench 11 to continue to move downward and into the bottom frame 12. Then, the design of the fixing plate 1601 and the first air rod 1602 drives the tube body 1605 limited in the end plate 1603 to move, so that the tube body 1605 can be inserted into the valve body 18. At end 8, by turning on the water pump 1604, water inside the bottom frame 12 will be drawn in by the water pump 1604 and transported to the valve body 18 through the pipe 1605. The sealing performance of the valve body 18 can be judged by visually observing whether the valve body 18 leaks when transporting water. In this case, by turning on the valve switch at the valve body 18, and then threading the liquid flow sensor 19 into the valve body 18, water inside the bottom frame 12 will be drawn in by the water pump 1604 and transported to the valve body 18 through the pipe 1605. The flow rate of the valve body 18 can be checked by the liquid flow sensor 19, avoiding unevenness on the inner surface of the valve body 18, which is well sealed under the same model.By rotating the threaded rod 10 in the reverse direction, the worktable 11 on the outer surface of the threaded rod 10 can be moved upward. When it moves to the inspection component 13 area, the air pump 1302 can be turned on, and the air blown out by the delivery pipe 1303 can be used to remove the water stains on the outer surface of the valve body 18 during inspection. In addition, by pulling the limit rod 21 upward to separate it from the worktable 11, the worktable 11 will rotate synchronously as the threaded rod 10 is continuously rotated. The continuous rotation of the worktable 11 allows the valve body 18, which is limited on the outer surface of the worktable 11, to contact the air blown out by the delivery pipe 1303 at multiple angles, which facilitates the cleaning of water stains on the surface of the valve body 18 during the discharge process. When the worktable 11 moves to the material receiving trough 14 on one side of the main body 1, the limit rod 21 is pulled upward to separate it from the worktable 11, and then the collection plate is driven by the second air rod 1701. The movement of plate 1702 synchronously moves connecting plate 1703, causing magnetic posts 1704 on the outer surface of connecting plate 1703 to magnetically attract and insert into holes on one side of inner plate 2004. Then, the second air rod 1701 retracts, causing inner plate 2004 to stop engaging with limiting rod 21, thus separating them. This allows the user to manually slide top cover 9 to remove valve body 18 from auxiliary frame 8. Alternatively, by placing valve body 18 to be tested inside top frame 1501 and manually rotating the round handle 1503 at screw 1502, screw 1502 can be moved forward, limiting the valve body 18 inside top frame 1501. This facilitates the operator coating the surface of valve body 18 with magnetic powder, and the concentration of the magnetic powder indicates whether cracks have appeared in valve body 18, allowing for direct inspection of valve body 18 from the outside of main body 1.

[0037] In summary, this multi-sensor-based valve inspection process and equipment, during use, involves manually sliding the top cover 9 along the surface of the auxiliary frame 8 to open the auxiliary frame 8. The operator then places the valve body 18 to be inspected inside the frame 2001. By rotating the inner rod 2002 in the middle of the frame 2001 clockwise, the inner rod 2002 and the padding layer 2003 on its end surface move downwards synchronously, thereby limiting and fixing the valve body 18 in the middle of the frame 2001. The second air rod 1701 drives the collection plate 1702 to move. The movement of the collection plate 1702 will synchronously drive the connecting plate 1703 to move. The magnetic column 1704 on the outer surface of the connecting plate 1703 is magnetically attracted and inserted into the hole on one side of the inner plate 2004. Then, the operator inserts the limiting rod 21 from the top of the main body 1 into the bottom frame 12. Then, the retraction of the second air rod 1701 drives the collection plate 1702 and the connecting plate 1703 to reset. At the same time, the magnetic column 1704 separates from the hole in the inner plate 2004.

[0038] By rotating the threaded rod 10, the operator can simultaneously utilize the sliding limit design of the limiting rod 21 and the worktable 11 to facilitate the vertical movement of the worktable 11 on the outer surface of the threaded rod 10. When the operator rotates the worktable 11, it is positioned in the inspection component 13 area. Then, the oil cylinder 1306 drives the limiting sleeve 1304 to move. The limiting sleeve 1304 has a sufficiently long conveying pipe 1303 inside, so that the moving end of the conveying pipe 1303 will be inserted into one end of the valve body 18. The outer surface of the end of the conveying pipe 1303 is provided with a rubber sealing layer to maintain the sealing between the conveying pipe 1303 and the valve body 18 during installation. At this time, the valve body 18 is closed. By turning on the air pump 1302, gas is injected into the valve body 18 through the conveying pipe 1303. Then, the air pressure in the valve body 18 is detected by the conveying pipe 1303 on one side of the end of the conveying pipe 1303. The change in air pressure is used to determine whether the airtightness of the valve body 18 is good.

[0039] By rotating the threaded rod 10 again, the operator rotates the workbench 11 downward and it is inside the bottom frame 12. Then, through the design of the fixed plate 1601 and the first air rod 1602, the tube 1605 in the end plate 1603 is moved, so that the tube 1605 can be inserted into the end of the valve body 18. Then, by turning on the water pump 1604, the water inside the bottom frame 12 will be sucked in by the water pump 1604 and transported to the inside of the valve body 18 through the tube 1605. The sealing performance of the valve body 18 can be judged by visually observing whether the valve body 18 leaks water when transporting water.

[0040] The system can be activated by opening the valve switch at the valve body 18, and then threading the liquid flow sensor 19 into the valve body 18. By turning on the water pump 1604, water inside the bottom frame 12 will be drawn in by the water pump 1604 and transported to the valve body 18 through the pipe 1605. The liquid flow sensor 19 can be used to check the flow rate of the valve body 18, thus preventing unevenness from appearing on the inner surface of the valve body 18, which is well-sealed under the same model.

[0041] By rotating the threaded rod 10 in the opposite direction, the worktable 11 on the outer surface of the threaded rod 10 can be moved upward. When it moves to the inspection component 13 area, the air pump 1302 can be turned on, so that the gas blown out by the conveying pipe 1303 can be used to remove the water stains that appear on the outer surface of the valve body 18 during inspection. In addition, by pulling the limit rod 21 upward to separate it from the worktable 11, the worktable 11 will rotate synchronously as the threaded rod 10 is continuously rotated. The continuous rotation of the worktable 11 allows the valve body 18, which is limited on the outer surface of the worktable 11, to contact the gas blown out by the conveying pipe 1303 at multiple angles, which facilitates the cleaning of water stains on the surface of the valve body 18 during the discharge process.

[0042] When the workbench 11 moves to the material chute 14 on one side of the main body 1, the limiting rod 21 is pulled upward to separate it from the workbench 11. Then, the second air rod 1701 drives the collection plate 1702 to move. The movement of the collection plate 1702 will synchronously drive the connecting plate 1703 to move. The magnetic column 1704 on the outer surface of the connecting plate 1703 is magnetically attracted and inserted into the hole on one side of the inner plate 2004. Then, the second air rod 1701 retracts, which will cause the inner plate 2004 to stop engaging with the limiting rod 21 and separate, making it convenient for the user to manually slide the top cover 9 to remove the valve body 18 in the auxiliary frame 8.

[0043] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.

2. A valve inspection process based on multiple sensors, used in the valve inspection equipment based on multiple sensors as described in claim 1, characterized in that, Includes the following steps: S1: Open the auxiliary frame (8) by manually sliding the top cover (9) along the surface of the auxiliary frame (8). Then, the operator places the valve body (18) to be tested inside the frame (2001). By rotating the inner rod (2002) in the middle of the frame (2001) clockwise, the pad (2003) on the end surface of the inner rod (2002) and the inner rod (2002) will move downward synchronously, thereby limiting and fixing the valve body (18) placed in the middle of the frame (2001). Then, the second air rod (1701) drives the collection plate (17... 02) Movement: The movement of the assembly plate (1702) will synchronously drive the connecting plate (1703) to move, and the magnetic column (1704) on the outer surface of the connecting plate (1703) will magnetically attract and insert into the hole on one side of the inner plate (2004). Then, the operator will insert the limiting rod (21) from the top of the main body (1) through the workbench (11) into the bottom frame (12). Then, the retraction of the second air rod (1701) will drive the assembly plate (1702) and the connecting plate (1703) to reset, and at the same time, the magnetic column (1704) will separate from the hole in the inner plate (2004). S2: By rotating the threaded rod (10) by the operator, and simultaneously using the sliding limit design of the limit rod (21) and the worktable (11), the worktable (11) on the outer surface of the threaded rod (10) can move in the up and down direction. When the operator rotates the worktable (11), it is in the inspection component one (13) area. Then, the limit sleeve (1304) is moved by the oil cylinder (1306). The limit sleeve (1304) has a sufficiently long conveying pipe (1303) inside, so that the moving end of the conveying pipe (1303) will be stuck into the valve. A rubber sealing layer is provided on the outer surface of the end of the conveying pipe (1303) at one end of the main body (18) to maintain the sealing between the conveying pipe (1303) and the valve body (18) during installation. At this time, the valve body (18) is closed, and gas is injected into the valve body (18) by turning on the air pump (1302). Then, the air pressure sensor (1305) on one side of the end of the conveying pipe (1303) is used to detect the air pressure in the valve body (18). The change in air pressure is used to determine whether the air tightness of the valve body (18) is good. S3: By rotating the threaded rod (10) again, the operator rotates the workbench (11) downward and into the bottom frame (12). Then, through the design of the fixed plate (1601) and the first air rod (1602), the tube (1605) in the end plate (1603) is moved, so that the tube (1605) can be inserted into the end of the valve body (18). Then, by turning on the water pump (1604), the water inside the bottom frame (12) will be sucked in by the water pump (1604) and transported to the inside of the valve body (18) through the tube (1605). The sealing performance of the valve body (18) can be judged by visually observing whether the valve body (18) leaks water when transporting water. S4: Open the valve switch of the valve body (18). By turning on the water pump (1604), the water inside the bottom frame (12) will be sucked in by the water pump (1604) and transported to the inside of the valve body (18) through the pipe (1605). The flow rate of the valve body (18) can be checked by the liquid flow sensor (19), so as to avoid unevenness on the inner surface of the valve body (18) with good sealing under the same model. S5: By rotating the threaded rod (10) in the opposite direction, the worktable (11) on the outer surface of the threaded rod (10) can be moved upward. When it moves to the inspection component one (13) area, the air pump (1302) can be turned on, so that the gas blown out by the conveying pipe (1303) can be used to remove the water stains on the outer surface of the valve body (18) during inspection. In addition, by pulling the limit rod (21) upward, it is separated from the worktable (11). As a result, the worktable (11) will rotate synchronously by continuously rotating the threaded rod (10). The continuous rotation of the worktable (11) can make the valve body (18) limited on the outer surface of the worktable (11) come into contact with the gas blown out by the conveying pipe (1303) at multiple angles, which is convenient for cleaning the water stains on the surface of the valve body (18) during the discharge process. S6: When the workbench (11) moves to the material trough (14) on one side of the main body (1), the limit rod (21) is pulled upward to separate it from the workbench (11). Then, the second air rod (1701) drives the collection plate (1702) to move. The movement of the collection plate (1702) will drive the connecting plate (1703) to move synchronously. The magnetic column (1704) on the outer surface of the connecting plate (1703) is magnetically attracted and inserted into the hole on one side of the inner plate (2004). Then, the second air rod (1701) drives the inner plate (2004) to retract, so that the user can manually slide the top cover (9) to take out the valve body (18) in the auxiliary frame (8).
