Description

Technical Field

[0001] The present invention relates to the technical field of valve sealing detection, and more specifically, to a sealing detection device used in valve production. Background Art

[0002] A valve is a device used to control the flow of fluids. It can open, close, throttle or divert liquids, gases or slurry substances in pipelines. Valves are designed with different pressure levels to meet different working pressure requirements, and valves also need to maintain good sealing performance to prevent fluid leakage.

[0003] Usually valves are divided into marine valves and land valves according to the use environment. Valves in deep-sea environments need to withstand higher water pressure, so they are usually designed with higher pressure ratings, while land valves do not need to withstand extremely high water pressure and are relatively easy to maintain and inspect.

[0004] When testing the sealing performance of a valve, one end is usually closed and the other end is inflated to test the internal air pressure. The change in air pressure is used to determine whether the valve is leaking. However, for marine valves, unqualified marine valves will usually have their internal sealing structure changed when the water pressure is too high, causing the valve to leak. Existing valve sealing testing devices are unable to perform sealing tests on marine valves while simulating deep-sea water pressure, resulting in some marine valves leaking when used in the deep sea, reducing the accuracy of marine valve sealing testing.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0045] For example, see Figure 1-10 The present invention provides the following technical solutions: A sealing detection device for valve production, comprising a supporting mechanism 1, the supporting mechanism 1 comprising a first bracket 11, side plates 15 are fixedly connected to both sides of the first bracket 11, a first top plate 16 and a first bottom plate 13 are fixedly connected to the upper and lower sides of the first bracket 11, a second bracket 12 is fixedly connected to the upper side of the first top plate 16, and four universal wheels 14 are evenly fixedly connected to the lower side of the first bottom plate 13.

[0046] See also Figure 1 and Figure 2 A clamping mechanism 5 is provided on the upper side of the first bottom plate 13, and an air blocking mechanism 2, a rotating mechanism 4 and an inflation mechanism 3 are provided on the upper side of the first top plate 16 from left to right, a marine environment simulation mechanism 6 is provided on one side of the rotating mechanism 4, and a wiping mechanism 7 is provided on one side of the second bracket 12.

[0047] Specifically, the clamping mechanism 5 is used to position the land valve to prevent it from shaking during the sealing test, the air blocking mechanism 2 is used to block one end of the land valve and detect the air pressure changes inside it, the rotating mechanism 4 is used to rotate the handwheel on the land valve, the inflation mechanism 3 is used to inflate the inside of the land valve, the marine environment simulation mechanism 6 is used to simulate the water pressure of the marine valve in the deep sea environment and detect the air tightness of the marine valve in this state, and the wiping mechanism 7 is used to wipe the water source on the surface of the marine valve.

[0048] See also Figure 3 The air blocking mechanism 2 includes a first cylinder 21, which is fixedly connected to the upper side of the first top plate 16, and an output end of the first cylinder 21 is fixedly connected to a first connecting disk 24, a first sealing ring 23 is provided inside the first connecting disk 24, and a first pressure sensor 22 is fixedly connected to one side of the first connecting disk 24.

[0049] The extension and retraction of the output end of the first cylinder 21 is used to control the movement of the first connecting disk 24, so that it is away from one end of the land valve or close to one end of the land valve, thereby blocking one end of the land valve or opening one end of the land valve. The first pressure sensor 22 is used to detect the air pressure change inside the land valve. The first pressure sensor 22 can be a diaphragm sensor. The diaphragm sensor includes a sensitive flexible diaphragm, which is usually made of metal or special polymer materials. When the gas pressure acts on one side of the diaphragm, the diaphragm will bend or stretch accordingly according to the force. The deformation of the diaphragm will affect the capacitance between it and the fixed electrode. By measuring the change in capacitance, the applied pressure value can be determined. The diaphragm sensor then converts the pressure value into an electrical signal and sends it to the control box 41. The control box 41 determines whether the valve is leaking based on the change in the pressure value.

[0050] See also Figure 4 The inflation mechanism 3 includes a second cylinder 33, which is fixedly connected to the upper side of the first top plate 16, and the output end of the second cylinder 33 is fixedly connected to the second connecting disk 31, and the interior of the second connecting disk 31 is fixedly connected to the second sealing ring 32, and one side of the side plate 15 is fixedly connected to the first air compressor 35, and the output end of the first air compressor 35 is fixedly connected to the first air pipe 34, and the other end of the first air pipe 34 is fixedly connected to the input end of the second connecting disk 31.

[0051] Specifically, when the first air compressor 35 starts working, the compressed high-pressure air is transported to the interior of the second connecting disk 31 through the first air pipe 34. The extension and contraction of the output end of the second cylinder 33 is used to control the movement of the second connecting disk 31, thereby blocking and opening the other end of the land valve. When the other end of the land valve is blocked, the compressed gas enters the interior of the land valve through the second connecting disk 31.

[0052] See also Figure 5 The rotating mechanism 4 includes four first fixed columns 46, which are fixedly connected to the upper side of the first top plate 16, and the first slide plate 45 is slidably connected to the outer side of the first fixed column 46. The upper side of the first fixed column 46 is fixedly connected to the second top plate 44, and the upper side of the second top plate 44 is fixedly connected to the control box 41 and the third cylinder 42, and the output end of the third cylinder 42 is fixedly connected to the first rotating motor 43, and the output end of the first rotating motor 43 is fixedly connected to the four-claw clamping assembly 47.

[0053] Specifically, the extension and retraction of the output end of the third cylinder 42 is used to control the up and down movement of the first rotating motor 43, and the rotation of the output end of the first rotating motor 43 is used to control the rotation of the four-claw clamping assembly 47. The four-claw clamping assembly 47 is a four-axis cylinder that controls the movement of four claws respectively, thereby clamping or releasing the handwheel of the land valve. When the output end of the third cylinder 42 is fully extended, the four-claw clamping assembly 47 clamps the handwheel of the land valve. When the output end of the first rotating motor 43 rotates clockwise, the gas inside the land valve is isolated. When the output end of the first rotating motor 43 rotates counterclockwise, ventilation begins inside the land valve.

[0054] See also Figure 6 The clamping mechanism 5 includes four second fixed columns 54, which are fixedly connected to the upper side of the first bottom plate 13 and the other ends are fixedly connected to the first top plate 16, and the outer sides of the second fixed columns 54 are slidably connected with the second slide plate 52, and the upper side of the first bottom plate 13 is fixedly connected with the fourth cylinder 53, and the output end of the fourth cylinder 53 is fixedly connected with the second slide plate 52, and the upper side of the second slide plate 52 is fixedly connected with the double-claw clamping assembly 51, and the clamping end of the double-claw clamping assembly 51 is provided with a land valve.

[0055] Specifically, the extension and retraction of the output end of the fourth cylinder 53 is used to control the double-claw clamping assembly 51 to move up and down. The double-claw clamping assembly 51 is a double-axis cylinder that controls the movement of two clamping jaws respectively, thereby clamping or releasing the entire land valve.

[0056] When it is necessary to detect the sealing of the land valve housing, the output end of the fourth cylinder 53 is completely retracted. At this time, the double-claw clamping assembly 51 is lower than the upper plane of the first top plate 16. The manipulator places the land valve above the double-claw clamping assembly 51. The output end of the fourth cylinder 53 is fully extended to support the land valve. The double-claw clamping assembly 51 clamps the land valve for positioning. The output end of the first cylinder 21 extends to control the first connecting plate 24 to block one end of the land valve. The output end of the second cylinder 33 extends to control the second connecting plate 31 to block the other end of the land valve. At this time, the first air compressor 35 When the operation starts, a large amount of compressed gas is delivered to the interior of the land valve. The first pressure sensor 22 detects the air pressure inside the land valve in real time. When the air pressure inside the land valve reaches a certain value (the certain value is the standard air pressure that the land valve can withstand), the first air compressor 35 stops compressing the gas. Within one minute, the first pressure sensor 22 detects whether the air pressure inside the land valve changes. When the air pressure changes, the control box 41 determines that the land valve is not sealed enough. When the air pressure does not change, the control box 41 determines that the sealing of the land valve meets the standard.

[0057] When it is necessary to test the sealing performance of the valve flap inside the land valve, the output end of the third cylinder 42 is fully extended, and the four-claw clamping assembly 47 clamps the handwheel of the land valve. When the output end of the first rotating motor 43 rotates clockwise, the gas inside the land valve is isolated. The output end of the second cylinder 33 is extended to control the movement of the second connecting disk 31 to open the other end of the land valve. The first pressure sensor 22 detects in real time the air pressure value of the air separated by the valve flap inside the land valve. Within one minute, the first pressure sensor 22 detects whether the air pressure value of the air separated by the valve flap inside the land valve changes. When the air pressure value changes, the control box 41 determines that the sealing performance of the valve flap inside the land valve is insufficient. When the air pressure value does not change, the control box 41 determines that the sealing performance of the valve flap inside the land valve meets the standard.

[0058] The first cylinder 21 and the second cylinder 33 respectively control the first connecting plate 24 and the second connecting plate 31 to block the two ends of the land valve, and the first pressure sensor 22 detects the changes in the air pressure value inside the land valve in real time, thereby automatically detecting the sealing of the land valve shell, and when it is necessary to detect the sealing of the valve disc inside the land valve, the four-jaw clamping assembly 47 is controlled to rotate the handwheel of the land valve, so that the first pressure sensor 22 detects the air pressure value of the valve disc inside the land valve to separate the air in real time. This process does not require personnel to manually adjust the handwheel of the land valve, and achieves the effect of automatically detecting the sealing of various valve structures.

[0059] Embodiment 2: When testing the sealing performance of a valve, one end is usually closed and the other end is inflated to test the internal air pressure. The change in air pressure is used to determine whether the valve is leaking. However, for marine valves, unqualified marine valves usually have changes in their internal sealing structure when the water pressure is too high, causing the valve to leak. Existing valve sealing testing devices are unable to test the sealing performance of marine valves while simulating deep-sea water pressure, causing some marine valves to leak when used in the deep sea, reducing the accuracy of marine valve sealing testing. Therefore, the following structure is designed to solve the above technical problems.

[0060] See also Figure 7The marine environment simulation mechanism 6 includes a water tank 61, which is fixedly connected to the upper side of the first top plate 16, and a second air compressor 63 and a water pump 62 are fixedly connected to the upper side of the water tank 61. A simulation barrel 68 is provided on one side of the water tank 61 and is fixedly connected to the first top plate 16. A fifth cylinder 602 is hinged on the outer side of the simulation barrel 68, and the output end of the fifth cylinder 602 is hinged to a barrel cover 67. The barrel cover 67 is hinged to the simulation barrel 68, and an air inlet and an air inlet are provided on the upper side of the barrel cover 67. The air inlet, water inlet and water outlet of the barrel cover 67 are all provided with solenoid valves. The water inlet of the barrel cover 67 is fixedly connected with a water inlet pipe 66, and the other end of the water inlet pipe 66 is fixedly connected with the output end of the water pump 62. The input end of the water pump 62 is fixedly connected with a water pumping pipe 601, and the other end of the water pumping pipe 601 is fixedly connected with the water tank 61. The water outlet of the simulation barrel 68 is fixedly connected with a water outlet pipe 69, and the other end of the water outlet pipe 69 is fixedly connected with the water tank 61.

[0061] Specifically, the interior of the water tank 61 is used to store simulated water sources, and the second air compressor 63 is used to transport compressed gas to the interior of the ocean valve. The principle of the second air compressor 63 is the same as that of the first air compressor 35, which will not be elaborated on here. The interior of the simulation barrel 68 is used to simulate the water pressure of the ocean environment. The simulation barrel 68 can detect the internal water pressure value through a pressure sensor. The water pump 62 is used to extract the water source inside the water tank 61 into the simulation barrel 68. The extension and retraction of the output end of the fifth cylinder 602 is used to control the opening or closing of the barrel cover 67. The second pressure sensor 654 is used to detect the change of the air pressure value inside the ocean valve. Its principle is the same as that of the first pressure sensor 22, which will not be elaborated on here.

[0062] See also Figure 8 The air inlet of the barrel cover 67 is provided with an air inlet mechanism 65, and the air inlet mechanism 65 includes an air inlet disk 651, and the air inlet disk 651 is fixedly connected to the inside of the air inlet of the barrel cover 67, the input end of the air inlet disk 651 is fixedly connected to the second air pipe 64 and the other end of the second air pipe 64 is fixedly connected to the output end of the second air compressor 63, the lower side of the air inlet disk 651 is bolted to a marine valve, and the other end of the marine valve is bolted to an air blocking disk 653, the interior of the air blocking disk 653 is fixedly connected to a third sealing ring 652, and one side of the air blocking disk 653 is fixedly connected to a second pressure sensor 654.

[0063] Specifically, when it is necessary to test the sealing performance of the ocean valve, the output end of the fifth cylinder 602 retracts, and the control barrel cover 67 is opened. Before installation, one end of the ocean valve is blocked by the air blocking plate 653, and then the other end of the ocean valve is bolted to one side of the air inlet plate 651. At this time, the second air compressor 63 can deliver compressed gas to the interior of the ocean valve, and the output end of the fifth cylinder 602 extends, and the control barrel cover 67 is closed. The second air compressor 63 transmits compressed air to the interior of the ocean valve, and the water pump 62 draws the water source inside the water tank 61 into the simulation barrel 68. When the water pressure in the water tank 61 reaches the pressure value of the water pressure in the deep sea, the water pump 62 stops delivering water to the simulation barrel 68. When the second pressure sensor 654 detects that the pressure value inside the ocean valve reaches a certain value (the certain value is the standard air pressure value that this ocean valve can withstand), the second air compressor 63 stops delivering compressed air.

[0064] Within one minute, when the second pressure sensor 654 detects that the internal air pressure value of the ocean valve has changed, it means that when the ocean valve is subjected to excessive water pressure, the internal sealing structure has changed and the internal gas has leaked. The control box 41 determines that the sealing of this ocean valve is unqualified. When the second pressure sensor 654 detects that the internal air pressure value of the ocean valve has not changed, it means that when the ocean valve is subjected to excessive water pressure, the internal sealing structure has not changed and the internal gas has not leaked. The control box 41 determines that the sealing of this ocean valve is qualified.

[0065] Before opening the barrel cover 67 , part of the water source inside the simulated barrel 68 is first pumped into the water tank 61 to prevent the water source inside the simulated barrel 68 from overflowing due to excessive water pressure when the barrel cover 67 is opened.

[0066] By providing a simulation barrel 68, a second pressure sensor 654, a water pump 62 and a second air compressor 63, the marine valve can be tested for sealing while simulating the deep sea water pressure, thereby effectively preventing some marine valves from leaking when used in the deep sea, improving the accuracy of the marine valve sealing detection, and achieving the effect of high marine valve detection accuracy and high detection efficiency.

[0067] Embodiment 3: After the marine valves are inspected in the water tank 61, qualified marine valves need to be transferred to the packaging area for packaging. However, after the marine valves are inspected, a large amount of water will remain on the surface. If they are not wiped clean, when they are taken out, the water on their surface will not only drip everywhere, but also affect the subsequent packaging work. After the water on the surface of the marine valve is wiped, the water absorbed by the absorbent cotton cannot be quickly removed, resulting in a decrease in its absorption capacity when the marine valve is wiped again. Therefore, the following structure is designed to solve the above technical problems.

[0068] See also Fig. 9The wiping mechanism 7 includes a third bracket 72, the third bracket 72 is fixedly connected to one side of the second bracket 12, and a sixth cylinder 73 is fixedly connected to the lower side of the third bracket 72. The output end of the sixth cylinder 73 is fixedly connected to a second rotating motor 74, and the second rotating motor 74 is slidably connected to the third bracket 72. The output end of the second rotating motor 74 is fixedly connected to a water absorption assembly 71.

[0069] Specifically, the extension and retraction of the output end of the sixth cylinder 73 is used to control the movement of the second rotary motor 74, so that the multi-layer absorbent cotton 711 is close to or away from the ocean valve, and the rotation of the output end of the second rotary motor 74 is used to control the rotation of the multi-layer absorbent cotton 711.

[0070] See also Fig.10 The water absorption component 71 includes a wiping tube 713, the inner wall of which is evenly provided with a plurality of ventilation grooves 714, the ventilation grooves 714 are inclined grooves, each ventilation groove 714 is fixedly connected to a heating tube 712, and the interior of the wiping tube 713 is fixedly connected to multiple layers of water-absorbing cotton 711.

[0071] Specifically, the heating tube 712 is used to emit heat, and the emitted heat contacts the surface of the multi-layer absorbent cotton 711 through the ventilation groove 714.

[0072] When the barrel cover 67 is opened, the output end of the sixth cylinder 73 is fully extended, and the second rotary motor 74 controls the wiping cylinder 713 to rotate. Since the inner diameter of the multi-layer absorbent cotton 711 is larger than the outer diameter of the ocean valve, the multi-layer absorbent cotton 711 surrounds the ocean valve. While the multi-layer absorbent cotton 711 rotates, most of the water on the surface of the ocean valve is absorbed. After the water source is absorbed, the output end of the sixth cylinder 73 is fully retracted, and the next ocean valve to be tested is installed on one side of the air inlet disk 651 for testing. In this process, the ocean valve can be quickly cleaned. Water is removed and the next marine valve is quickly replaced, which speeds up the detection speed of the marine valve. The second rotating motor 74 continuously controls the wiping cylinder 713 to rotate, and the heating tube 712 starts and begins to emit heat. As the wiping cylinder 713 rotates, the ventilation groove 714 is an inclined groove, and the air is heated to high-temperature air through the heating tube 712. The high-temperature air is brought into the interior of the multi-layer absorbent cotton 711 through the rotation of the wiping cylinder 713, and the interior of the multi-layer absorbent cotton 711 is quickly dehumidified, which speeds up the evaporation rate of the water source inside the multi-layer absorbent cotton 711.

[0073] The multi-layer absorbent cotton 711 is controlled to rotate by the second rotating motor 74, which not only quickly wipes the water on the surface of the marine valve, but also allows the high-temperature air heated by the heating tube 712 to enter the interior of the multi-layer absorbent cotton 711 through the ventilation groove 714, and quickly dry the water inside the multi-layer absorbent cotton 711, thereby accelerating the evaporation rate of the water inside the multi-layer absorbent cotton 711 and improving the subsequent absorption rate of the water on the surface of the marine valve, thereby achieving the effects of high efficiency in removing water from the surface of the marine valve and high efficiency in detecting the marine valve.

[0074] Obviously, the embodiments described above are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
