Description

Technical Field

[0001] The invention relates to the technical field of breathing valve calibration, in particular to a breathing valve calibration platform with a quick installation structure. Background Art

[0002] A breathing valve is a valve that not only ensures that the storage tank space is isolated from the atmosphere within a certain pressure range, but can also communicate with the atmosphere (breathe) when the pressure exceeds or falls below this pressure range. Its function is to prevent the storage tank from being damaged due to overpressure or vacuum, and at the same time reduce the evaporation loss of the stored liquid. Setting a breathing valve can not only reduce the gas emission in the tank, thereby reducing the pollution to the atmosphere, but also prevent the storage tank from being damaged due to overpressure or instability due to ultra-vacuum, which plays a certain role in promoting safety and environmental protection.

[0003] The breathing valve is mainly composed of a valve seat, a valve cover, a protective cover and two sets of opening and closing devices controlled by vacuum and pressure. The opening and closing devices include valve discs, guide rods, springs, spring seats and sealing rings. When the pressure in the tank reaches the rated exhalation positive pressure, the pressure valve disc opens and the steam in the tank is discharged; when the vacuum in the tank reaches the rated inhalation negative pressure, the vacuum valve disc opens and air enters.

[0004] At present, when the existing breathing valve calibration station conveys air into the breathing valve, due to the variety of breathing valve models, the connection between the air pump and the breathing valve is not easy to seal, causing air to leak from the valve port, affecting the accuracy of the calibration value. Summary of the invention

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A breathing valve test bench with a quick installation structure, comprising a table frame, the table frame is used to support the breathing valve and the test component, and a lower groove is provided on the top of the table frame;

[0007] A fixing component, and connecting fasteners fixedly connected to both sides of the outer surface of the fixing component, wherein the top of the fixing component is clamped with a breathing valve to be inspected;

[0008] A verification component, which is used to inject air into the breathing valve to perform air tightness verification, and a connection block fixedly connected to the surface of the verification component;

[0009] The fixing component is fixedly connected to the middle of the top of the table frame through the lower groove, the two sides of the outer surface of the fixing component are fixedly connected to the stabilizing component through connecting fasteners, the two sides of the outer surface of the stabilizing component are fixedly connected to the lower groove on the top of the table frame through clamping parts, and the interior of the stabilizing component is fixedly connected to the verification component through connecting parts; the breathing valve is mainly composed of a valve seat, a valve cover, a protective cover and two sets of opening and closing devices controlled by vacuum and pressure. Before calibrating the breathing valve, the breathing valve needs to be fixed on the verification table, and the staff places the valve seat above the fixing component, aligns the through hole set at the bottom of the valve seat with the fixing component, and fixes the valve seat by clamping through the fixing component. Then the staff opens the verification component to convey air into the breathing valve, pressurizes the breathing valve, and observes the changes in the micro-pressure count value, thereby completing the pressure check of the breathing valve.

[0010] Wherein, the verification component includes an air pump, and the staff starts the air pump to inject air into the breathing valve to increase the pressure in the breathing valve. A connecting ring is fixedly connected to the top of the outer surface of the air pump, and the air pump is fixedly connected to the stabilizing support component through the connecting ring. Connecting blocks are fixedly connected to both sides of the outer surface of the air pump, and a clamping ring is fixedly connected to the bottom of the connecting block. The clamping ring is fixedly connected to the bottom of the air pump through the connecting block, and a sealing guide is fixedly connected to the middle of the bottom of the clamping ring, and a valve-attaching component is fixedly connected to the bottom edge of the clamping ring. Before injecting air, the staff moves the sealing guide downward and inserts it into the tank mouth of the breathing valve. At this time, the clamping ring covers the tank mouth, and the sealing guide is attached to the inner wall of the tank mouth, and the valve-attaching component outside the clamping ring is arranged on the outer wall of the breathing valve to support the clamping ring and the sealing guide.

[0011] Preferably, the sealing guide includes a sealing ring, the lower surface of which is fixedly connected with a bending rod, the bending rod is an elastic structure with a small upper part and a large lower part, the bending rods are distributed in a circle on the lower surface of the sealing ring, the middle of the inner surface of the bending rod is fixedly connected with an inner ring, the surface of the inner surface of the bending rod away from the side of the bending rod is fixedly connected with a segmented block, when inserted into the tank mouth, the larger end of the bending rod is squeezed and contracted inwardly with the inner wall of the tank mouth, and the segmented block is moved inwardly when the bending rod contracts, and the segmented block is arranged opposite to the bending rod, and the inner surface of the segmented block is penetrated by a connecting belt, and the middle of the segmented blocks are connected by the connecting belt, so that multiple segmented blocks are displaced at the same frequency to avoid offset when offsetting inward, so as to facilitate the sealing connection between the sealing guide and different types of breathing valves.

[0012] Preferably, the valve-sticking member, the valve-sticking member and the sealing guide are layered on the surface of the clamping ring. When the sealing guide moves downward and penetrates into the tank mouth, the valve-sticking member includes a connecting plate, which is fixedly connected to the bottom edge of the clamping ring. The outer surface of the connecting plate is fixedly connected to a slide plate. As the sealing guide moves downward, the valve-sticking member generates friction with the outer wall of the tank mouth, so that the slider drives the extension rod and the components connected to its surface to slide upward in the slide plate. The inner surface of the slide plate is slidably connected to the slider, and the lower surface of the slider is fixedly connected to the extension rod. The surface of the extension rod away from one end of the slider is rotatably connected to an adjusting bead. When the slider slides to the top of the slide plate, it is limited by the connecting plate and stops moving. At this time, the components connected to the surface of the extension rod are displaced due to the shape of the outer wall of the tank mouth.

[0013] Preferably, both sides of the outer surface of the adjusting bead are fixedly connected with hollow connecting blocks. Since the outer wall of the breathing valve tank mouth is mostly arc-shaped, the adjusting bead is affected by the curvature of the outer wall of the tank mouth and drives the hollow connecting blocks on both sides to rotate at the bottom end of the extension rod to reach a tilted state. The outer surface of the hollow connecting block close to the sealing guide is fixedly connected with an arc column, so that the arc groove provided on the surface of the arc column fits against the outer wall of the tank mouth. The outer surface of the arc column is provided with an arc groove, and the surface of the hollow connecting block away from the sealing guide is fixedly connected with an inclined column. The inclined column is against the outer wall of the tank mouth according to the shape of the outer wall of the tank mouth, thereby supporting and limiting the adjusting bead, so that the arc groove fits stably on the outer wall of the tank mouth, so that when the sealing guide conveys air into the tank body, the valve component stably supports the sealing guide from the outside to maintain the stability of air delivery and avoid deviations in the verification data due to external influences.

[0014] Preferably, the stabilizing support assembly includes a bent frame, which is fixedly connected to the edge of the lower groove through a clamping piece at the bottom. Two bent frames are provided, and a middle support plate is fixedly connected between the opposite surfaces of the two bent frames. The upper surfaces of the bent frame and the middle support plate are fixedly connected with special-shaped frame plates.

[0015] Preferably, the upper surface of the special-shaped frame plate is fixedly connected to a horizontal plate, the upper surface of the horizontal plate is fixedly connected to a support frame, the surface of the horizontal plate is fixedly connected to a limit block, and the inner surface of the limit block is provided with a card groove. Before verification, the staff starts the hydraulic press to make the lifting plate drive the air pump to move downward, so that the sealing guide at the bottom of the air pump is connected to the tank mouth, so as to facilitate the sealed delivery of air.

[0016] Preferably, the support frame includes a beam frame, a sleeve plate is fixedly connected to the middle of the outer surface of the beam frame, a lifting plate is slidably connected to the lower surface of the sleeve plate, the lifting plate is fixedly connected to the top of the connecting ring, a bending frame is fixedly connected to the upper surface of the sleeve plate, and a connecting block is fixedly connected to the lower surface of the bending frame away from the sleeve plate.

[0017] Preferably, the outer surface of the connecting block is fixedly connected to a lower support rod, the surface of the lower support rod is fixedly connected to a ring, the ring is fixedly clamped in the slot, and the ring is sleeved on the outer surface of the air pump, the ring is sleeved on the outside of the air pump to limit the air pump and avoid deviation when the air pump moves, resulting in inaccurate docking between the sealing guide and the tank mouth.

[0018] Preferably, the fixing assembly includes a supporting platform, which is fixedly connected to the middle of the inner part of the central support plate through connecting fasteners on both sides of the outer surface, a clamping hole is opened at the edge of the upper surface of the supporting platform, and a positioning piece is clamped on the inner surface of the clamping hole. The top of the supporting platform is clamped with the breathing valve to be inspected through the positioning piece. The staff places the breathing valve on the top of the supporting platform, aligns the through hole at the bottom edge of the valve seat with the clamping hole, and then passes the positioning piece through the through hole and the clamping hole to install and fix the breathing valve.

[0019] Preferably, the positioning member includes a top ball, the top of the top ball is fixedly connected to a rotating rod, the outer surface of the top ball is threadedly connected to a covered curved rod, and the surface of the covered curved rod near one end of the table frame is fixedly connected to a support rod. Before the positioning member is inserted into the through hole and the clamping hole, the staff rotates the rotating rod so that the rotating rod drives the top ball to rotate in the covered curved rod until it is in a state of being fitted with the covered curved rod. At this time, the expansion rod is not supported by the top ball and is in a vertical state with the through hole and the clamping hole, so that the expansion rod can pass through the through hole and the clamping hole to extend below the supporting platform, and the surface of the covered curved rod away from the table frame is fixedly connected to the clamping rod, and the outer surface of the clamping rod is fixedly connected to a ring. After the expansion rod is penetrated, the staff rotates the rotating rod so that the rotating rod drives the top ball to rotate downward, and at this time, multiple expansion rods are extended outward by the bottom ends supported by the top ball, thereby quickly fixing the valve seat on the supporting platform. When removing the valve seat, the staff rotates the rotating rod upward so that the rotating rod drives the top ball to return to the covered curved rod, and the expansion rod is reset to facilitate being taken out from the through hole and the clamping hole.

[0020] The present invention provides a breathing valve test bench with a quick installation structure. It has the following beneficial effects:

[0021] 1. The breathing valve test bench with a quick installation structure has a truncated cone-shaped elastic structure with a small top and a large bottom through a bending rod. When inserted into the tank mouth, the larger end of the bending rod is squeezed and contracted inwardly by the inner wall of the tank mouth. When the bending rod contracts, it drives the segmented blocks to move inward. The segmented blocks are connected in the middle by a connecting belt, so that multiple segmented blocks move at the same frequency, avoiding the offset phenomenon when shifting inward, so as to facilitate the sealing connection between the sealing guide and breathing valves of different models.

[0022] 2. The breathing valve inspection table with a quick installation structure is layered on the surface of the clamping ring by means of a valve sticking part and a sealing guide. When the sealing guide moves downward and penetrates into the tank mouth, the valve sticking part generates friction with the outer wall of the tank mouth as the sealing guide moves downward, so that the slider drives the extension rod and the components connected to its surface to slide upward in the slider. When the slider slides to the top of the slider, it is limited by the connecting plate and stops moving. At this time, the components connected to the surface of the extension rod are affected by the shape of the outer wall of the tank mouth and are displaced.

[0023] 3. The breathing valve calibration table with a quick installation structure has an outer wall of the breathing valve tank mouth which is mostly arc-shaped. The adjusting bead is affected by the curvature of the outer wall of the tank mouth and drives the hollow connecting blocks on both sides to rotate at the bottom end of the extension rod to reach an inclined state, so that the curved groove opened on the surface of the arc column fits against the outer wall of the tank mouth. The inclined column is against the outer wall of the tank mouth according to the shape of the outer wall of the tank mouth, thereby supporting and limiting the adjusting bead, so that the curved groove fits stably against the outer wall of the tank mouth, so that when the sealing guide conveys air into the tank body, the valve member stably supports the sealing guide from the outside to maintain the stability of air delivery and avoid deviation of the calibration data due to external influences.

[0024] 4. The breathing valve calibration bench with a quick installation structure has a staff member rotating the rotating rod before the positioning piece is inserted into the through hole and the clamping hole, so that the rotating rod drives the top ball to rotate in the covered curved rod until it is in a fit with the covered curved rod. At this time, the expansion rod is not supported by the top ball and is in a vertical state with the through hole and the clamping hole, so that the expansion rod can pass through the through hole and the clamping hole to extend to the bottom of the bearing platform. After the expansion rod is penetrated, the staff member rotates the rotating rod so that the rotating rod drives the top ball to rotate downward. At this time, multiple expansion rods are supported by the top ball and the bottom ends extend outward, thereby quickly fixing the valve seat on the bearing platform. When removing the valve seat, the staff member rotates the rotating rod upward so that the rotating rod drives the top ball to return to the covered curved rod, and the expansion rod is reset to facilitate being taken out from the through hole and the clamping hole.

[0025] 5. The breathing valve calibration bench with a quick installation structure is mounted on the outside of the air pump through a sleeve ring to limit the position of the air pump to prevent the air pump from shifting when moving, resulting in inaccurate docking between the sealing guide and the tank mouth.

Before calibrating the breathing valve, the breathing valve needs to be fixed on the verification table, and the staff places the valve seat above the fixing component 4, aligns the through hole set at the bottom of the valve seat with the fixing component 4, and fixes the valve seat by snap-fitting the fixing component 4. Then the staff opens the verification component 3 to convey air into the breathing valve, pressurizes the breathing valve, and observes the changes in the micro-pressure counter value, thereby completing the pressure check of the breathing valve.

[0042] The fixing assembly 4 includes a supporting platform 41, which is fixedly connected to the middle of the inner part of the middle support plate 23 through connecting fasteners on both sides of the outer surface. A clamping hole 43 is opened at the edge of the upper surface of the supporting platform 41, and a positioning member 42 is clamped on the inner surface of the clamping hole 43. The top of the supporting platform 41 is clamped with the breathing valve to be inspected through the positioning member 42. The staff places the breathing valve on the top of the supporting platform 41, and aligns the through hole at the bottom edge of the valve seat with the clamping hole 43, and then passes the positioning member 42 through the through hole and the clamping hole 43 to install and fix the breathing valve.

[0043] The positioning member 42 includes a top ball 423, the top of the top ball 423 is fixedly connected to a rotating rod 422, the outer surface of the top ball 423 is threadedly connected to a covered curved rod 425, and the surface of the covered curved rod 425 close to one end of the table frame 1 is fixedly connected to a support rod 426. Before the positioning member 42 is inserted into the through hole and the clamping hole 43, the staff rotates the rotating rod 422 so that the rotating rod 422 drives the top ball 423 to rotate in the covered curved rod 425 until it fits with the covered curved rod 425. At this time, the support rod 426 is not supported by the top ball 423 and is in a vertical state with the through hole and the clamping hole 43, so that the support rod 426 can pass through the through hole and the clamping hole 43 and extend to Below the supporting platform 41, the surface of the coated bent rod 425 away from the end of the table frame 1 is fixedly connected with a clamping rod 424, and the outer surface of the clamping rod 424 is fixedly connected with a ring 421. After the expansion rod 426 is penetrated, the staff rotates the rotating rod 422 so that the rotating rod 422 drives the top ball 423 to rotate downward. At this time, multiple expansion rods 426 are supported by the top ball 423 and extend outward at the bottom, so that the valve seat is quickly fixed on the supporting platform. When removing the valve seat, the staff rotates the rotating rod 422 upward so that the rotating rod 422 drives the top ball 423 to return to the coated bent rod 425, and the expansion rod 426 is reset to facilitate being taken out from the through hole and the clamping hole 43.

[0044] The second embodiment is based on the first embodiment. Figure 2 , Figure 5 and Figure 6 The stabilizing support assembly 2 shown includes a bent frame 22, which is fixedly connected to the edge of the lower groove 5 through a clamping piece at the bottom. Two bent frames 22 are provided, and a middle support plate 23 is fixedly connected between the opposite surfaces of the two bent frames 22. The upper surfaces of the bent frames 22 and the middle support plate 23 are fixedly connected with a special-shaped frame plate 21.

[0045] The upper surface of the special-shaped frame plate 21 is fixedly connected with a transverse plate 24, the upper surface of the transverse plate 24 is fixedly connected with a support frame 25, the surface of the transverse plate 24 is fixedly connected with a limit block 26, and the inner surface of the limit block 26 is provided with a card slot 27. Before verification, the staff starts the hydraulic press to make the lifting plate 252 drive the air pump 32 to move downward, so that the sealing guide 36 at the bottom of the air pump 32 is connected with the tank mouth, so as to facilitate the sealed delivery of air.

[0046] The support frame 25 includes a beam frame 253, a sleeve plate 251 is fixedly connected to the middle of the outer surface of the beam frame 253, a lifting plate 252 is slidably connected to the lower surface of the sleeve plate 251, the lifting plate 252 is fixedly connected to the top of the connecting ring 31, a bending frame 256 is fixedly connected to the upper surface of the sleeve plate 251, and a connecting block 255 is fixedly connected to the lower surface of the bending frame 256 away from the sleeve plate 251.

[0047] The outer surface of the connecting block 255 is fixedly connected to the lower support rod 254, and the surface of the lower support rod 254 is fixedly connected to the ring 257. The ring 257 is fixedly clamped in the slot 27, and the ring 257 is sleeved on the outer surface of the air pump 32. The ring 257 is sleeved on the outside of the air pump 32 to limit the air pump 32 to avoid deviation when the air pump moves, resulting in inaccurate docking between the sealing guide 36 and the tank mouth.

[0048] The third embodiment is based on the first and second embodiments. Figures 7 to 9 As shown, the verification component 3 includes an air pump 32. The staff starts the air pump 32 to inject air into the breathing valve to increase the pressure in the breathing valve. A connecting ring 31 is fixedly connected to the top of the outer surface of the air pump 32. The air pump 32 is fixedly connected to the stabilizing support component 2 through the connecting ring 31. Connecting blocks 33 are fixedly connected to the outer surfaces of the air pump 32 on both sides. A clamping ring 34 is fixedly connected to the bottom of the connecting block 33. The clamping ring 34 is fixedly connected to the bottom of the air pump 32 through the connecting block 33. A sealing guide 36 is fixedly connected to the middle of the bottom of the clamping ring 34. A valve member 35 is fixedly connected to the bottom edge of the clamping ring 34. Before injecting air, the staff moves the sealing guide 36 downward and inserts it into the tank mouth of the breathing valve. At this time, the clamping ring 34 covers the tank mouth, and the sealing guide 36 fits against the inner wall of the tank mouth, while the valve member 35 outside the clamping ring 34 is arranged on the outer wall of the breathing valve to support the clamping ring 34 and the sealing guide 36.

[0049] The sealing guide 36 includes a sealing ring 362, and a bending rod 361 is fixedly connected to the lower surface of the sealing ring 362. The bending rod 361 is a truncated cone-shaped elastic structure with a small upper part and a large lower part. The bending rods 361 are distributed in a circular shape on the lower surface of the sealing ring 362. The inner surface of the bending rod 361 is fixedly connected to an inner ring 365 in the middle. The inner surface of the bending rod 361 is fixedly connected to a segment block 364 on the surface away from the bending rod 361. When the bending rod 361 is inserted into the tank mouth, the bending rod 36 The larger end of the tumbler 361 is squeezed against the inner wall of the tank mouth and shrinks inwards. When the bending rod 361 shrinks, the segmented block 364 is driven to move inwards. The segmented block 364 is arranged opposite to the bending rod 361. The inner surface of the segmented block 364 is penetrated by a connecting belt 363. The middle of the segmented block 364 is connected by the connecting belt 363, so that multiple segmented blocks 364 move at the same frequency, avoiding the deviation phenomenon when deviating inwards, so as to facilitate the sealing guide 36 to be sealed and connected with different types of breathing valves.

[0050] The valve-applying member 35 and the sealing guide 36 are layeredly arranged on the surface of the clamping ring 34. When the sealing guide 36 moves downward and penetrates into the tank mouth, the valve-applying member 35 includes a connecting plate 351, which is fixedly connected to the bottom edge of the clamping ring 34. The outer surface of the connecting plate 351 is fixedly connected to a slide plate 352. As the sealing guide 36 moves downward, the valve-applying member 35 generates friction with the outer wall of the tank mouth, so that the slider 353 drives the extension rod 354 and the components connected to its surface to slide upward in the slide plate 352. The inner surface of the slide plate 352 is slidably connected to the slider 353, and the lower surface of the slider 353 is fixedly connected to the extension rod 354. The surface of the extension rod 354 away from the end of the slider 353 is rotatably connected to an adjusting bead 357. When sliding to the top of the slider 352, the slider 353 is limited by the connecting plate 351 and stops moving. At this time, the components connected to the surface of the extension rod 354 are affected by the shape of the outer wall of the tank mouth and are displaced.

[0051] The outer surface of the adjusting bead 357 is fixedly connected with hollow connecting blocks 358 on both sides. Since the outer wall of the breathing valve tank mouth is mostly arc-shaped, the adjusting bead 357 is affected by the curvature of the outer wall of the tank mouth to drive the hollow connecting blocks 358 on both sides to rotate at the bottom end of the extension rod 354 to achieve a tilted state. The outer surface of the hollow connecting block 358 close to the sealing guide 36 is fixedly connected with an arc column 355, so that the curved groove 356 opened on the surface of the arc column 355 fits the outer wall of the tank mouth. The outer surface of the arc column 355 is provided with a curved groove 356, the surface of the hollow connecting block 358 away from the sealing guide 36 is fixedly connected with an inclined column 359, and the inclined column 359 is against the outer wall of the tank mouth according to the shape of the outer wall of the tank mouth, so as to support and limit the adjusting bead 357, so that the curved groove 356 is stably fitted on the outer wall of the tank mouth, so that when the sealing guide 36 conveys air into the tank body, the valve member 35 can stably support the sealing guide 36 from the outside, so as to maintain the stability of air delivery and avoid deviation of the verification data due to external influences.

[0052] When in use, the breathing valve is mainly composed of a valve seat, a valve cover, a protective cover and two sets of opening and closing devices controlled by vacuum and pressure. Before calibrating the breathing valve, the breathing valve needs to be fixed on the calibration bench. The staff places the valve seat above the fixing component 4, aligns the through hole set at the bottom of the valve seat with the fixing component 4, and fixes the valve seat through the fixing component 4. Then the staff opens the calibration component 3 to convey air into the breathing valve, pressurizes the breathing valve, and observes the changes in the micro-pressure counter value, thereby completing the pressure check of the breathing valve.

[0053] The staff places the breathing valve on the top of the supporting platform 41, aligns the through hole at the bottom edge of the valve seat with the clamping hole 43, and then passes the positioning member 42 through the through hole and the clamping hole 43 to install and fix the breathing valve.

[0054] Before the positioning member 42 is inserted into the through hole and the clamping hole 43, the staff rotates the rotating rod 422 so that the rotating rod 422 drives the top ball 423 to rotate in the covered curved rod 425 until it is in a fit with the covered curved rod 425. At this time, the expansion rod 426 is not supported by the top ball 423 and is in a vertical state with the through hole and the clamping hole 43, so that the expansion rod 426 can pass through the through hole and the clamping hole 43 and extend to the bottom of the supporting platform 41. After the expansion rod 426 passes through, the staff rotates the rotating rod 422 so that the rotating rod 422 drives the top ball 423 to rotate downward. At this time, multiple expansion rods 426 are supported by the top ball 423 and extend outward at the bottom, thereby quickly fixing the valve seat on the supporting platform. When removing the valve seat, the staff rotates the rotating rod 422 upward so that the rotating rod 422 drives the top ball 423 to return to the covered curved rod 425, and the expansion rod 426 is reset to facilitate being removed from the through hole and the clamping hole 43.

[0055] Before the inspection, the staff starts the hydraulic press so that the lifting plate 252 drives the air pump 32 to move downward, so that the sealing guide 36 at the bottom of the air pump 32 is connected with the tank mouth, so as to facilitate the sealed delivery of air.

[0056] The collar 257 is sleeved on the outside of the air pump 32 to limit the position of the air pump 32 to prevent the air pump from being offset when moving, resulting in inaccurate docking between the sealing guide 36 and the tank mouth.

[0057] The staff starts the air pump 32 to inject air into the breathing valve to increase the pressure inside the breathing valve. Before injecting air, the staff moves the sealing guide 36 downward and inserts it into the mouth of the breathing valve. At this time, the clamping ring 34 covers the mouth of the mouth, and the sealing guide 36 fits against the inner wall of the mouth of the mouth. The valve-fitting part 35 outside the clamping ring 34 is set on the outer wall of the breathing valve to support the clamping ring 34 and the sealing guide 36.

[0058] The bending rod 361 is a cone-shaped elastic structure with a small top and a large bottom. When inserted into the tank mouth, the larger end of the bending rod 361 is squeezed and contracted inwardly by the inner wall of the tank mouth. When the bending rod 361 contracts, it drives the segmented block 364 to move inward. The segmented blocks 364 are connected in the middle by a connecting belt 363, so that multiple segmented blocks 364 move at the same frequency, avoiding displacement when shifting inward, so as to facilitate the sealing guide 36 to be sealed and connected with different types of breathing valves.

[0059] The valve member 35 and the sealing guide 36 are arranged in layers on the surface of the clamping ring 34. When the sealing guide 36 moves down and penetrates into the tank mouth, the valve member 35 moves down with the sealing guide 36 and produces friction with the outer wall of the tank mouth, so that the slider 353 drives the extension rod 354 and the components connected to its surface to slide upward in the slide plate 352. When sliding to the top of the slide plate 352, the slider 353 is limited by the connecting plate 351 and stops moving. At this time, the components connected to the surface of the extension rod 354 are affected by the shape of the outer wall of the tank mouth and are displaced.

[0060] Since the outer wall of the breathing valve tank mouth is mostly arc-shaped, the adjusting bead 357 is affected by the curvature of the outer wall of the tank mouth and drives the hollow connecting blocks 358 on both sides to rotate at the bottom end of the extension rod 354 to reach an inclined state, so that the curved groove 356 opened on the surface of the arc column 355 fits against the outer wall of the tank mouth, and the inclined column 359 is against the outer wall of the tank mouth according to the shape of the outer wall of the tank mouth, thereby supporting and limiting the adjusting bead 357, so that the curved groove 356 fits stably on the outer wall of the tank mouth, so that when the sealing guide 36 transports air into the tank body, the valve component 35 can stably support the sealing guide 36 from the outside to maintain the stability of air transportation and avoid deviation of the verification data due to external influences.
