Description

Technical Field

[0001] The present invention relates to the technical field of air valve detection, and in particular to an air valve detection device. Background Art

[0002] A damper is a device used to control air flow, commonly found in ventilation systems, air conditioning systems, and various industrial piping systems. It is mainly used to regulate, guide, or prevent the flow of air in the pipe. The damper detection equipment is a special tool or system used to evaluate and test the performance of the damper, including air volume measurement devices, sealing test equipment, and temperature resistance test equipment. The sealing test equipment is used to detect the sealing performance of the damper when it is closed to prevent gas leakage.

[0003] When testing air valves, current sealing testing equipment first installs a closed air valve in the test system, and creates a condition similar to the actual working condition by pressurizing or vacuuming the system. Usually, a certain positive or negative pressure is applied and maintained for a period of time, and a pressure sensor is used to detect whether there is a leak. However, before the existing test, the air valve is usually fixed to the mounting frame by using a flange, or the air valve is clamped and fixed to the mounting frame by using multiple clamps. Using flanges for fixing has good sealing but is time-consuming, which affects the test efficiency, while using clamps saves time but has poor sealing, which affects the test effect. Secondly, if air valves of different sizes need to be tested, corresponding flanges and tooling fixtures need to be prepared to adapt to the interfaces of different diameters or shapes of air valves of different sizes, resulting in increased testing costs.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 and Figure 3 A wind valve detection device includes a detection chamber 1 and a sealing mechanism 4. The detection chamber 1 is provided with a supporting mechanism 2 for installing and supporting the wind valve to be detected, the supporting mechanism 2 is provided with a mounting mechanism 3, the mounting mechanism 3 is provided with a sealing mechanism 4, and the detection chamber 1 is provided with a locking mechanism 5 for locking the position of the mounting mechanism 3 and applying pressure to the sealing mechanism 4.

[0034] Reference Figure 1 A cavity is opened inside the detection chamber 1, an air outlet is opened on the top wall of the cavity, an air inlet is opened on the right wall of the cavity, the air inlet is connected to the air compressor, and a pressure sensor is installed on the inner wall of the cavity of the detection chamber 1 (the pressure sensor is a prior art and will not be elaborated here).

[0035] Reference Figures 1 to 3 The support mechanism 2 includes a connecting tube 21, which is fixedly connected to the air outlet. A rectangular support plate 22 is fixed to the side wall of the connecting tube 21. A hole that is compatible with the connecting tube 21 is opened through the middle of the support plate 22. A matrix-shaped support column is fixedly connected between the bottom wall of the support plate 22 and the top wall of the detection chamber 1. A rubber gasket 23 is detachably installed on the top wall of the support plate 22.

[0036] Before testing, the air valve to be tested is placed on the support plate 22 and the rubber gasket 23, and is automatically corrected by the installation mechanism 3 so that the air valve is aligned with the connecting tube 21 and the air outlet of the testing chamber 1. At the same time, the installation mechanism 3 adapts to air valves to be tested of different sizes and limits them, and the installation efficiency is high; the installation mechanism 3 drives the sealing mechanism 4 to move to the appropriate position, and the four sides and four corners of the air valve to be tested are automatically sealed by the sealing mechanism 4, and the sealing effect is good; the adjustment position of the air valve to be tested, the installation mechanism 3 and the sealing mechanism 4 are locked by the locking mechanism 5, and the sealing effect is enhanced.

[0037] During testing, the air compressor is connected to the air inlet of the testing chamber 1, and the air outlet is connected to the air valve to be tested. By adjusting the compressor, a certain amount of air is filled into the cavity of the testing chamber 1 to reach the required test pressure. The actual pressure value is monitored by the pressure sensor to detect the sealing of the air valve.

[0038] Reference Figure 1 and Figure 3 The mounting mechanism 3 includes a centering calibration component 31 provided on the supporting mechanism 2 for centering the air valve to be tested and an adaptive component 32 provided on the centering calibration component 31 for adapting to air valves to be tested of different sizes.

[0039] Reference Figures 3 to 6 The centering calibration component 31 includes a rotating pushing piece 311. The bottom wall of the support plate 22 is driven to rotate by an electric slider and is connected to a rotating pushing piece 311 arranged on the outside of the connecting cylinder 21. The rotating pushing piece 311 consists of a circular ring member rotatably connected to the support plate 22 and four pushing blocks evenly fixed on the outer wall of the circular ring member along the circumferential direction. The pushing block is inclined away from the circular ring member; the bottom wall of the support plate 22 is slidably connected to an L-shaped seat 312 corresponding to the pushing block through a spring 1 (not shown in the figure) along the circumferential direction. The horizontal section of the L-shaped seat 312 is fixedly connected to a trapezoidal block 313 corresponding to the pushing block on the side close to the rotating pushing piece 311. The side of the trapezoidal block 313 away from the L-shaped seat 312 is adapted to the inclined side wall of the pushing block.

[0040] Reference Figures 3 to 6The adaptive component 32 includes a T-shaped adjustment frame 321, and the upper part of the vertical section of the L-shaped seat 312 is horizontally slidably penetrated by the T-shaped adjustment frame 321. The T-shaped adjustment frame 321 is symmetrically fixedly connected to a sliding rod 322 that slides through the L-shaped seat 312 on one side close to the vertical section of the L-shaped seat 312. A spring 2 that is sleeved on the outer wall of the sliding rod 322 is fixedly connected between the T-shaped adjustment frame 321 and the vertical section of the L-shaped seat 312. A plurality of positioning holes 323 are opened up and down at one end of the T-shaped adjustment frame 321 that slides through the L-shaped seat 312. A hole position that matches the positioning hole 323 is opened in the middle of the vertical section of the L-shaped seat 312. The top wall of the vertical section of the L-shaped seat 312 is slidably connected to a positioning plate 324 through a spring 3. The bottom wall of the positioning plate 324 is fixed with a positioning rod 325 that matches the hole position on the L-shaped seat 312 and the positioning hole 323.

[0041] The personnel places the air valve to be tested on the rubber gasket 23. In the initial state, the pushing block pushes the corresponding trapezoidal block 313 in all directions. The circular ring and the pushing block are driven to rotate by the electric slider, and the pushing block releases the pushing of the trapezoidal block 313. The initial state of the spring 1 connected between the L-shaped seat 312 and the support plate 22 is tensioned. When the trapezoidal block 313 is no longer pushed, the spring 1 contracts, driving the L-shaped seat 312 to slide on the support plate 22, and the vertical section of the L-shaped seat 312 slides close to the side wall of the support plate 22.

[0042] The movement of the L-shaped seat 312 drives the T-shaped adjustment frame 321 to move close to the air valve to be tested. Multiple L-shaped seats 312 drive the corresponding T-shaped adjustment frames 321 to push the air valve to be tested on the rubber gasket 23 from four directions to be centered. No manual position adjustment is required, which improves installation efficiency and ensures that the air valve to be tested can cover the connecting tube 21, so that the air valve to be tested is connected to the air outlet through the connecting tube 21.

[0043] According to the side length of the air valve to be tested, the positions of the T-shaped adjustment frame 321 and the sliding rod 322 on the L-shaped seat 312 are adaptively slid and adjusted, and the spring 2 is extended and retracted to adapt. The tension of the spring 2 ensures that the side wall of the T-shaped adjustment frame 321 is always in close contact with the air valve to be tested, so as to adapt to the air valves to be tested of different sizes and limit them, thereby increasing the practicality of the device.

[0044] Reference Figure 1 and Figure 3 The sealing mechanism 4 includes a sealing component 41 provided on the supporting mechanism 2 for sealing the four sides and four corners of the air valve to be detected, and a pressurizing component 42 provided on the sealing component 41 for enhancing the sealing effect of the sealing component 41.

[0045] Reference Figure 3 、 Figure 7 、 Figure 8 and Figure 9The sealing component 41 includes an inverted L-shaped slide 411 arranged on the adaptive component 32 and a seal arranged on the inverted L-shaped slide 411. A slide rail is provided on the bottom wall of the T-shaped adjustment frame 321. The inverted L-shaped slide 411 is slidably connected to the slide rail through an electric slider. The seal includes a rubber gasket 2 412 and a rubber sealing block 413. The bottom wall of the inverted L-shaped slide 411 is detachably installed with a Z-shaped rubber gasket 2 412. The bottom wall of the upper horizontal section of the rubber gasket 2 412 is horizontally slidably connected to the rubber sealing block 413 through a spring 4 (not shown in the figure).

[0046] Reference Figure 3 and Figure 7 The pressurizing assembly 42 includes a slide groove 421. Two slide grooves 421 are symmetrically opened on the side wall of the vertical section of the inverted L-shaped slide 411. The two slide grooves 421 are connected to a pressurizing plate 422 for sliding up and down through a spring five (not shown in the figure). The bottom wall height of the pressurizing plate 422 is higher than the top wall height of the lower horizontal section of the rubber gasket 412. The sliding section side wall of the T-shaped adjustment frame 321 is symmetrically connected to a movable telescopic plate 423 for sliding up and down. The movable telescopic plate 423 is arranged above the pressurizing plate 422.

[0047] The T-shaped adjustment frame 321 drives the sealing assembly 41 to move to a position close to the air valve to be tested. When the air valve to be tested is limited by the T-shaped adjustment frame 321, the initial state of the inverted L-shaped slide 411 is that a small part of it is slidably connected to the T-shaped adjustment frame 321 (such as Figure 8 As shown, the inverted L-shaped slide 411 is driven by the electric slider to slide horizontally on the slide rail of the bottom wall of the T-shaped adjustment frame 321. The inverted L-shaped slide 411 drives the rubber gasket 2 412 to move together. The multiple inverted L-shaped slides 411 slide in a counterclockwise order until the rubber gasket 2 412 completely covers the four sides of the bottom wall of the air valve to be tested and the rubber gasket 1 23. The position of the inverted L-shaped slide 411 after sliding is that most of it is slidably connected to the T-shaped adjustment frame 321 (as shown). Figure 9 As shown), the rubber gasket 2 412 seals the four sides where the bottom wall of the air valve to be tested is in contact with the rubber gasket 1 23.

[0048] The initial state of the rubber sealing block 413 in the middle of the bottom of the rubber gasket 2 412 is stationary. During the movement of the rubber gasket 2 412, the rubber sealing block 413 gradually approaches the four corners where the bottom wall of the air valve to be tested and the rubber gasket 1 23 are in contact, until the rubber sealing block 413 is blocked by the corresponding right angle. In order to adapt to the movement of the rubber gasket 2 412, the rubber sealing block 413 slides at the bottom of the rubber gasket 2 412, and the spring 4 is stretched. The tension of the spring 44 keeps the rubber sealing block 413 always tightly attached to the corresponding right angle. The rubber sealing block 413 seals the four corners where the bottom wall of the air valve to be tested and the rubber gasket 1 23 are in contact to achieve automatic sealing. The rubber gasket 2 412, the rubber sealing block 413 and the rubber gasket 1 23 fit together without leaving any sealing dead angles.

[0049] Reference Figure 1 、 Figure 2 and Figure 10 The locking mechanism 5 includes a hydraulic rod 51. The top wall of the detection chamber 1 is installed with hydraulic rods 51 corresponding to the four sides of the support plate 22 in the circumferential direction. The top walls of the output ends of the four hydraulic rods 51 are fixedly connected to a cross 52 set above the support plate 22. The bottom walls of the four ends of the cross 52 are fixedly connected to a lower pressure block 53 and a U-shaped pressure plate 54. The lower pressure block 53 is set above the corresponding positioning plate 324, and the U-shaped pressure plate 54 is set above the corresponding movable telescopic plate 423.

[0050] The initial state of the hydraulic rod 51 is that the output end is extended. After the seal is installed and before testing, the output end of the hydraulic rod 51 moves downward, driving the cross 52 to move downward close to the air valve to be tested. The cross 52 applies downward pressure to the air valve to be tested, locking the position of the air valve to be tested to prevent displacement during the testing process.

[0051] The lower pressing block 53 moves downward with the cross 52 and approaches the corresponding positioning plate 324, pushing the positioning plate 324 and the positioning rod 325 downward. The spring 3 is compressed, and the positioning rod 325 slides downward into the hole position and the positioning hole 323 on the corresponding L-shaped seat 312 to lock the position between the T-shaped adjustment frame 321 and the L-shaped seat 312. The U-shaped pressing plate 54 moves downward with the cross 52 and approaches the corresponding movable telescopic plate 423, pushing the movable telescopic plate 423 downward on the corresponding T-shaped adjustment frame 3 21 side wall slides, the output end bottom wall of the movable telescopic plate 423 gradually approaches the pressure plate 422, and is close to the top wall of the pressure plate 422, pushing the pressure plate 422 to slide downward on the inverted L-shaped slide 411. The spring five is stretched, and the bottom wall of the pressure plate 422 gradually is close to the top wall of the lower horizontal section of the rubber gasket 2 412, and exerts pressure on the top wall of the lower horizontal section of the rubber gasket 2 412, so that the rubber gasket 2 412 is in close contact with the rubber gasket 1 23, so as to enhance the sealing effect of the rubber gasket 2 412.

[0052] During testing, the air compressor is connected to the air inlet of the testing chamber 1, and the air outlet is connected to the air valve to be tested. By adjusting the compressor, a certain amount of air is filled into the cavity of the testing chamber 1, and the actual pressure value is monitored by the pressure sensor to detect the sealing of the air valve.

[0053] The specific operation steps of the air valve detection device are as follows: before the detection, the air valve to be detected is placed on the support plate 22 and the rubber gasket 23, the rotating pushing member 311 drives the multiple L-shaped seats 312 to drive the corresponding T-shaped adjustment frame 321 to push the air valve to be detected on the rubber gasket 23 from four directions to be centered, the T-shaped adjustment frame 321 and the sliding rod 322 are adaptively slid and adjusted on the L-shaped seat 312 according to the side length of the air valve to be detected; the inverted L-shaped slide 411 is driven until The rubber gasket 2 412 completely covers the four sides where the bottom wall of the air valve to be tested is in contact with the rubber gasket 1 23, and the rubber gasket 212 blocks the four sides where the bottom wall of the air valve to be tested is in contact with the rubber gasket 1 23; the hydraulic rod 51 drives the cross 52 to apply downward pressure to the air valve to be tested, locking the position of the air valve to be tested, the positioning rod 325 locks the position between the T-shaped adjustment frame 321 and the L-shaped seat 312, and the pressure plate 422 applies pressure to the top wall of the lower horizontal section of the rubber gasket 2 412.

[0054] During the inspection, the air compressor is connected to the air inlet of the inspection chamber 1, and the air outlet is connected to the air valve to be inspected. A certain amount of air is filled into the cavity of the inspection chamber 1 by adjusting the compressor, and the actual pressure value is monitored by the pressure sensor. The pressure is maintained for a period of time, and the air pressure changes in the cavity of the inspection chamber 1 are used to determine whether the air valve is leaking. If the air pressure can be maintained for a period of time, it indicates that the air valve is well sealed. If the air pressure is gradually decreasing, the air valve is not sealed enough, so as to detect the sealing of the air valve.
