Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a pipeline connection sealing testing device for oxygen production equipment. Background Technology

[0002] Oxygen generating equipment is widely used in fields such as medical treatment and industrial production. In medical settings, a stable and leak-free oxygen supply is crucial to ensuring the effectiveness of patient treatment. If an oxygen leak occurs, it may lead to insufficient oxygen concentration inhaled by the patient, affecting the treatment process. In industrial production, oxygen leaks not only waste resources but also pose a risk of serious safety accidents such as explosions. Therefore, the sealing of the pipeline connections of oxygen generating equipment is directly related to the safety and stability of the equipment.

[0003] Currently, various testing devices have been put into use to ensure the sealing of oxygen production equipment pipeline connections. For example, patent CN220356612U discloses a pipeline interface sealing testing device. This device sets a sealing testing component and a sealing testing component on the outside of the gas pipeline interface connector. The upper and lower ferrule plates wrap around the outside of the gas pipeline interface connector to form a testing chamber, which effectively prevents air leakage in the testing chamber and ensures the accuracy of the gas seal test at the gas pipeline interface connector, making it easier for users to obtain more accurate test data.

[0004] Based on the search of the aforementioned patents and the discovery of existing equipment, it is found that when the aforementioned equipment is used, it can only detect whether there is an air leak at the connection. When an air leak is detected, it cannot quickly and accurately locate the leak point. Maintenance personnel need to spend a lot of time and effort to check each section one by one, which not only reduces maintenance efficiency, but may also increase the risk of equipment operation due to long delays, affecting the normal use of oxygen generating equipment. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a pipeline connection sealing detection device for oxygen production equipment, which has the advantage of detecting leaks and solves the problem mentioned in the background art that existing devices cannot quickly and accurately locate leaks.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipeline connection sealing detection device for oxygen generators, comprising an upper housing, a lower housing, a pressure gauge, a fixing block, and a fixing screw. The upper housing is disposed on top of the lower housing, and the pressure gauge is fixedly installed on the top of the upper housing. The fixing block is fixedly connected to the bottom of the front and back sides of the upper housing and the top of the front and back sides of the lower housing. The fixing screw is disposed inside the fixing block. A leak detection mechanism is fixedly installed on the rear side of the bottom of the lower housing. The leak detection mechanism includes a water tank, which is fixedly installed on the rear side of the bottom of the lower housing. The water tank contains foamed water, and a water outlet pipe is connected to the left side of the water tank. An air blowing component is connected to the right side of the front side of the water tank.

[0007] As a preferred embodiment of the present invention, the air blowing assembly includes a gas cylinder connector, which is connected to the front of the water tank, and the input end of the gas cylinder connector is connected to a gas cylinder.

[0008] As a preferred embodiment of this invention, the right side of the water tank is connected to a water inlet pipe, which is a right-angle bend with its opening facing upwards.

[0009] As a preferred embodiment of this utility model, the back of the water tank is inlaid with an observation window through a through groove, and the observation window is made of transparent acrylic.

[0010] As a preferred embodiment of this invention, the surface of the water outlet pipe is provided with a valve.

[0011] As a preferred embodiment of this invention, a sealing plug is threaded onto the top of the surface of the water inlet pipe, and the sealing plug is used to seal the opening of the water inlet pipe.

[0012] As a preferred embodiment of this invention, the surface of the sealing plug is provided with anti-slip stripes, and the anti-slip stripes are multiple and distributed in a ring at equal intervals.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model adds a leak detection mechanism. This mechanism uses foam water in the water tank to visually display the location of the leak, significantly improving maintenance efficiency and reducing equipment operation risks. When a leak is detected, the leak detection mechanism is activated, and air is blown into the water tank through the air blowing component to generate foam in the foam water. If there is a leak in the pipeline, the foam will accumulate at the leak point, thereby achieving accurate location of the leak.

[0015] 2. This utility model provides a stable air source for the water tank by setting up an air blowing component, which is designed to connect to the gas cylinder with a gas cylinder connector. This ensures that the foam water can generate enough foam, thereby improving the sensitivity and reliability of leak detection.

[0016] 3. This utility model features a water inlet pipe with a right-angle bend and an upward-facing opening. This design facilitates the addition of foam water to the water tank while preventing the foam water from overflowing during testing, thus ensuring the smooth progress of the testing work.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, the present invention provides an oxygen generator pipeline connection sealing detection device, including an upper housing 1, a lower housing 2, a pressure gauge 3, a fixing block 4, and a fixing screw 5. The upper housing 1 is located on top of the lower housing 2. The pressure gauge 3 is fixedly installed on the top of the upper housing 1. The fixing block 4 is fixedly connected to the bottom of the front and back of the upper housing 1 and the top of the front and back of the lower housing 2. The fixing screw 5 is located inside the fixing block 4. A leak detection mechanism 6 is fixedly installed on the rear side of the bottom of the lower housing 2. The leak detection mechanism 6 includes a water tank 61, which is fixedly installed on the rear side of the bottom of the lower housing 2. The water tank 61 is filled with foam water. A water outlet pipe 62 is connected to the left side of the water tank 61, and an air blowing component 63 is connected to the right side of the front of the water tank 61.

[0023] refer to Figure 1 , Figure 2 and Figure 3 The air blowing assembly 63 includes a gas cylinder connector 631, which is connected to the front of the water tank 61, and the input end of the gas cylinder connector 631 is connected to a gas cylinder 632.

[0024] As a technical optimization of this utility model, by setting up an air blowing component 63, which is designed to connect the gas cylinder connector 631 to the gas cylinder 632, a stable air source is provided to the water tank 61, ensuring that the foam water can generate enough foam and improving the sensitivity and reliability of leak detection.

[0025] refer to Figure 1 , Figure 2 and Figure 3 The right side of the water tank 61 is connected to the water inlet pipe 7, which is a right-angle bend with the opening facing upwards.

[0026] As a technical optimization of this utility model, by setting up a water inlet pipe 7, which adopts a right-angle bend and has an upward opening, it is convenient to add foam water into the water tank 61, and can also prevent foam water from overflowing during the testing process, thus ensuring the smooth progress of the testing work.

[0027] refer to Figure 1 , Figure 2 and Figure 3 The back of the water tank 61 is inlaid with an observation window 8 through a groove. The observation window 8 is made of transparent acrylic.

[0028] As a technical optimization of this utility model, a transparent acrylic observation window 8 is provided on the back of the water tank 61. The transparent acrylic material has good light transmittance, and the operator can clearly see the flow of foam water and the generation of foam in the water tank 61 through the observation window 8.

[0029] refer to Figure 1 , Figure 2 and Figure 3 A valve 9 is installed on the surface of the water outlet pipe 62.

[0030] As a technical optimization of this utility model, by setting a valve 9 on the surface of the water outlet pipe 62, the discharge of foam water in the water tank 61 can be controlled. When it is necessary to discharge the foam water in the water tank 61, the valve 9 is opened and the foam water is discharged through the water outlet pipe 62. When the valve 9 is closed, the water tank 61 remains sealed to ensure the stability of the air pressure during the detection process.

[0031] refer to Figure 1 , Figure 2 and Figure 3 A sealing plug 10 is threaded onto the top of the surface of the water inlet pipe 7. The sealing plug 10 is used to seal the opening of the water inlet pipe 7.

[0032] As a technical optimization of this utility model, by setting a sealing plug 10, after injecting foamed water into the water tank 61, the sealing plug 10 is tightened on the top of the water inlet pipe 7 to form a sealed structure. During the testing process, even if the air pressure inside the water tank 61 increases, the sealing plug 10 can prevent gas from escaping from the water inlet pipe 7, ensuring the airtightness of the testing environment.

[0033] refer to Figure 1 , Figure 2 and Figure 3 The surface of the sealing plug 10 is provided with anti-slip stripes 11, and there are multiple anti-slip stripes 11 distributed in a ring at equal intervals.

[0034] As a technical optimization of this utility model, by setting anti-slip stripes 11, the friction between the operator's hand and the sealing plug 10 is increased, making it easier to tighten and loosen the sealing plug 10 and improving the convenience of operation. When the operator tightens or loosens the sealing plug 10, the anti-slip stripes 11 can effectively prevent the hand from slipping, making the operation easier and more efficient.

[0035] The working principle and usage process of this utility model are as follows: During use, the upper housing 1 and lower housing 2 are wrapped around the connection point of the oxygen generator pipeline, ensuring a tight fit between the detection device and the pipeline. The upper housing 1 and lower housing 2 are fixed by passing the fixing screw 5 through the fixing block 4. At this time, the pressure gauge 3 installed on the top of the upper housing 1 begins to work, performing a preliminary check for leaks at the pipeline connection. If the pressure gauge 3 reads normally, it indicates a good pipeline seal. If the pressure gauge 3 shows an abnormal drop, it indicates a leak at the pipeline connection, requiring further inspection of the leak point. The gas cylinder connector 631 is opened, allowing gas from the gas cylinder 632 to enter the water tank 61 through the gas cylinder connector 631, creating pressure within the water tank 61 and causing the foam water to produce foam. Then, the valve 9 on the surface of the outlet pipe 62 is opened to discharge the foam water to the pipeline connection. The operator can observe the foam at the connection point; as gas escapes from the leak point, it pulls surrounding foam towards the leak point, forming a noticeable foam accumulation, thus identifying the leak point.

[0036] In summary, this oxygen generator pipeline connection sealing detection device, by adding a leak detection mechanism 6, utilizes foam water in the water tank 61 to visually display the leak location, significantly improving maintenance efficiency and reducing equipment operation risks. When a leak is detected, the leak detection mechanism 6 is activated, and air is blown into the water tank 61 through the air blowing component 63, causing the foam water to generate foam. If there is a leak in the pipeline, the foam will accumulate at the leak point, thereby achieving precise location of the leak. This solves the problem mentioned in the background art that existing devices cannot quickly and accurately locate leak points.
