[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] With the increasing automation of industrial production, the reliability of the sealing performance of safety valves 100, as a key component ensuring the safe operation of equipment, is of paramount importance. However, in existing industrial production environments, traditional safety valve leak detection devices have certain limitations, mainly including the following: Traditional detection components have a simple structure, mainly consisting of a basic pressure sensor, a manually controlled valve, and a simple data display instrument. They cannot monitor the sealing and leakage of safety valve 100 in real time with high accuracy. When the sensor or internal components are damaged, traditional detection devices struggle to detect it immediately, leading to inaccurate results and impacting industrial production safety. Traditional detection devices are often made of opaque metal, making it impossible to visually observe leaks and hindering fault diagnosis and timely handling. Furthermore, traditional detection devices are susceptible to environmental factors (such as corrosion and wear) during long-term use, resulting in reduced detection accuracy.

[0023] like Figures 1 to 4 As shown, the safety valve sealing leakage detection device of this embodiment includes a safety valve 100, a first transparent shell 6, and a second transparent shell 7. The safety valve 100 includes a valve body 1, an inlet pipe 2, and an outlet pipe 3. The inlet pipe 2 extends vertically, and the outlet pipe 3 extends horizontally. An inlet flange assembly 4 is provided on the inlet pipe 2, and an outlet flange assembly 5 is provided on the outlet pipe 3. The first transparent shell 6 is connected to the inlet pipe 2 and has a first detection chamber 601, within which the inlet flange assembly 4 is disposed. The first detection chamber 601 is filled with water to submerge the inlet flange assembly 4. The second transparent shell 7 is connected to the outlet pipe 3 and has a second detection chamber 701, within which the outlet flange assembly 5 is disposed. The second detection chamber 701 is filled with water to submerge the outlet flange assembly 5.

[0024] In use, the safety valve sealing leakage detection device of this invention utilizes the characteristics of a transparent housing to determine the sealing performance of the safety valve 100 by observing the formation of air bubbles within the housing. The valve body 1 of the safety valve 100 is connected to an inlet pipe 2 and an outlet pipe 3, and is respectively equipped with an inlet flange assembly 4 and an outlet flange assembly 5. These two flange assemblies are placed in detection chambers within two transparent housings, which are filled with water to submerge the flange assemblies, thereby detecting leakage through the flow of water and the formation of air bubbles.

[0025] When safety valve 100 is operating normally, there should be no leaks in the inlet pipe 2 and outlet pipe 3. If there is a leak in the inlet flange or outlet flange assembly 5, compressed air will enter the water through the leak point, forming bubbles. These bubbles rise in the water and can be observed through the transparent housing. The operator can determine the location and extent of the leak by observing the bubbles in the first transparent housing 6 and the second transparent housing 7.

[0026] Compared to traditional detection devices, the safety valve sealing leakage detection device of this invention can monitor the sealing status of the safety valve 100 in real time, promptly detect leakage problems, and thus ensure production safety. By observing the size and number of bubbles, the degree of leakage can be determined more accurately, improving detection accuracy. The transparent shell makes the leakage situation readily apparent, facilitating quick diagnosis and problem location by operators. Because the detection chamber is filled with water, this device is less susceptible to environmental factors such as corrosion and wear compared to traditional metal detection devices, thus ensuring detection accuracy and long-term stability. The transparent shell facilitates cleaning and inspection, reducing maintenance difficulty and cost. By quickly and accurately detecting leakage problems in the safety valve 100, timely measures can be taken to avoid production accidents, reduce downtime, and thus improve production efficiency.

[0027] In some embodiments, the top of the first transparent shell 6 is open, and the bottom plate of the first transparent shell 6 is provided with a first perforation 602 for the air intake pipe 2 to pass through. The first perforation 602 is sealed to the air intake pipe 2. The first transparent shell 6 includes a first shell 61 and a second shell 62. The first shell 61 and the second shell 62 are detachably connected, and the first perforation 602 is defined between the first shell 61 and the second shell 62.

[0028] like Figure 2 and Figure 3 As shown, the top of the first transparent shell 6 is open to facilitate the entry of the air inlet flange assembly 4 into the first detection chamber 601, and also to facilitate the addition of water to the first detection chamber 601. The first perforation 602 on the base plate is for the air inlet pipe 2 to pass through and seal with it, ensuring that no external air enters during the detection process, thereby avoiding affecting the accuracy of the detection results. The first transparent shell 6 consists of a first shell 61 and a second shell 62, which are detachably connected, facilitating the engagement of the first transparent shell 6 with the air inlet pipe 2, and making assembly and disassembly convenient. The first perforation 602 ensures a sealed fit between the air inlet pipe 2 and the first perforation 602, preventing leakage.

[0029] In some embodiments, the sidewall of the first transparent shell 6 is provided with a first drain outlet, and the first drain outlet is detachably provided with a first water-blocking plug 8. For example... Figure 2 and Figure 3 As shown, a drain outlet is provided on the side wall of the first transparent shell 6. The main purpose of this design is to facilitate the drainage of water from the detection chamber after use of the detection device, making cleaning and maintenance easier. The removable water-blocking plug at the first drain outlet can be removed when drainage is needed, and serves to block water when drainage is not needed, preventing accidental water leakage.

[0030] In some embodiments, the first shell 61 is provided with a first connecting hole, and the second shell 62 is provided with a second connecting hole. The first shell 61 and the second shell 62 are connected by a first fastener 9 passing through the first connecting hole and the second connecting hole.

[0031] Connecting holes are provided on the first housing 61 and the second housing 62, ensuring precise alignment and connection between the two housings. A first fastener 9 (e.g., a bolt, nut, etc.) passes through the first and second connecting holes, securely connecting the first housing 61 and the second housing 62 together. The use of fasteners ensures a stronger connection between the two housings, improving the structural stability of the entire device and enabling it to withstand vibration and pressure in industrial environments. The connecting holes and fasteners allow for quick assembly and disassembly of the housings, which is especially important for maintenance and component replacement. The fasteners provide uniform clamping force, ensuring no gaps between the housings, thus improving sealing performance and preventing water and air bubble leakage. This configuration simplifies the housing structure, eliminating the need for complex welding or bonding processes and reducing production costs. The connecting holes and fasteners can accommodate different materials, whether metal, plastic, or composite materials, achieving a secure connection through this method. The fastener connection reduces connection failures due to material fatigue or aging, improving the long-term reliability of the detection device. If adjustments to the relative position between the housings are needed, the fastener connection allows for fine-tuning to accommodate different installation requirements.

[0032] In some embodiments, the bottom plate of the first shell 61 has a first semicircular groove 611, and the bottom plate of the second shell 62 has a second semicircular groove 621. The first semicircular groove 611 and the second semicircular groove 621 are arranged opposite to each other to form a first through hole 602. The inner wall of the first semicircular groove 611 is provided with a first sealing gasket 10, and the inner wall of the second semicircular groove 621 is provided with a second sealing gasket 11.

[0033] like Figure 3 As shown, semicircular grooves are provided on the bottom plates of the first shell 61 and the second shell 62, respectively. These two semicircular grooves are arranged opposite to each other. When the two shells are joined, they together form a complete circular perforation, namely the first perforation 602. Sealing gaskets are provided on the inner walls of the first semicircular groove 611 and the second semicircular groove 621, and these sealing gaskets play a sealing role when the two shells are joined.

[0034] The use of a sealing gasket ensures a tight seal in the area of ​​the first perforation 602, preventing gas or liquid leakage, which is crucial for maintaining the accuracy of the detection device. The semi-circular groove facilitates precise alignment, ensuring that the first housing 61 and the second housing 62 can be correctly assembled, thus guaranteeing the overall performance of the device. The semi-circular groove and sealing gasket simplify the installation process; simply align the two housings correctly and secure the fasteners. Because the sealing gasket effectively prevents leakage, maintenance and downtime costs due to leaks are reduced. The sealing gasket can absorb some of the stress caused by temperature changes or vibration, thereby improving the durability of the connection. Appropriate sealing gasket materials can be selected based on different operating conditions and media to meet various sealing requirements. The semi-circular groove and sealing gasket provide additional safety, ensuring the reliability of the device during long-term use.

[0035] In some embodiments, the second transparent shell 7 has opposing first and second sidewalls. The first sidewall has a second perforation 702 through which the air outlet pipe 3 passes, and the second sidewall has a third perforation 703 through which the air outlet pipe 3 passes. The second transparent shell 7 includes an upper shell 71 and a lower shell 72, which are rotatably connected. The second perforation 702 and the third perforation 703 are defined between the upper shell 71 and the lower shell 72.

[0036] like Figure 2 and Figure 4 As shown, the second transparent shell 7 has two opposing sidewalls, referred to as the first sidewall and the second sidewall, respectively. These two sidewalls are respectively provided with a second perforation 702 and a third perforation 703 for the passage of the air outlet pipe 3. The second transparent shell 7 consists of an upper shell 71 and a lower shell 72, which are connected in a flip-over manner. This arrangement allows the two shells to be joined in a specific way, thereby defining the positions of the second perforation 702 and the third perforation 703.

[0037] By providing perforations on both side walls, a flexible connection method for the outlet pipe 3 is provided, allowing adjustment of the pipe's direction and position according to actual needs. The arrangement between the upper shell 71 and the lower shell 72 ensures the sealing of the second perforation 702 and the third perforation 703, preventing gas leakage and ensuring the accuracy of the detection results. The flip-out connection of the upper shell 71 and the lower shell 72 makes maintenance and component replacement more convenient, allowing for quick opening and closing of the shells. The flip-out shell configuration facilitates cleaning of the interior, maintaining the cleanliness of the detection device and avoiding contamination and false alarms. The precise alignment between the upper shell 71 and the lower shell 72 ensures the accuracy of the second perforation 702 and the third perforation 703, thereby improving the overall installation accuracy of the device. The flip-out configuration allows the device to be adjusted according to different installation environments and requirements, increasing the device's adaptability. Quick and convenient maintenance and cleaning help reduce production line downtime and improve production efficiency.

[0038] In some embodiments, a third sealing gasket 12 is provided on the inner wall of the second perforation 702, and a fourth sealing gasket 13 is provided on the inner wall of the third perforation 703.

[0039] like Figure 4 As shown, a third sealing gasket 12 and a fourth sealing gasket 13 are respectively provided on the inner walls of the second perforation 702 and the third perforation 703. These sealing gaskets provide a sealing effect when the outlet pipe 3 passes through. The sealing gaskets effectively prevent gas leakage through the perforations, ensuring that the pressure and state inside the detection chamber are not affected by external factors, thereby guaranteeing the accuracy of the detection results. The use of sealing gaskets improves the sealing performance at the perforations, maintaining a good sealing effect even under high pressure or vibration conditions. The sealing gaskets can be selected and customized according to the size of the outlet pipe 3 to ensure optimal sealing performance. The installation of the sealing gaskets usually allows for easy replacement; when the sealing gaskets are worn or damaged, they can be quickly replaced, reducing maintenance time and costs. The sealing gaskets can absorb some of the stress caused by temperature changes or vibration, thereby improving the durability of the connection. By improving the sealing performance at the perforations, the reliability of the overall device is also improved, helping to prevent equipment failure or production accidents caused by leakage. The sealing gaskets can be made of appropriate materials according to different working environments (such as high temperature, high pressure, corrosive media, etc.) to ensure good sealing performance under various environments.

[0040] In some embodiments, the top plate of the second transparent shell 7 is provided with a water injection hole 704, the bottom plate of the second transparent shell 7 is provided with a second drain hole, and the second drain hole is detachably provided with a second water-blocking plug 14.

[0041] The top plate of the second transparent shell 7 has a water injection hole 704 for injecting water into the detection chamber for leak detection. The bottom plate of the second transparent shell 7 has a drain hole for draining the water in the detection chamber after the test is completed. The removable water-blocking plug at the drain hole can be removed when drainage is needed, and serves to block water when drainage is not needed.

[0042] The water injection port 704 makes it easier to inject water into the detection chamber, improving operational convenience. The drain port and removable water-retaining plug allow for quick drainage of the detection chamber after testing, saving time and reducing labor. The drainage function makes cleaning the detection device easier; operators can thoroughly empty the detection chamber, ensuring no residue affects the next test. The water-retaining plug prevents accidental water leakage when not in operation, reducing safety hazards in the working environment. The removable water-retaining plug facilitates inspection and replacement; if damaged or worn, it can be quickly replaced, avoiding complex maintenance procedures.

[0043] In some embodiments, one end of the upper shell 71 is rotatably connected to one end of the lower shell 72 via a hinge 15, and the other end of the upper shell 71 is detachably connected to the other end of the lower shell 72.

[0044] One end of the upper housing 71 is rotatably connected to one end of the lower housing 72 via a hinge 15. This configuration allows the upper housing 71 to be opened when necessary for observation and operation. The other end of the upper housing 71 is detachably connected to the other end of the lower housing 72, for example, using bolts or clips, for quick assembly and disassembly. The hinge 15 connection allows the upper housing 71 to be easily opened and closed, facilitating inspection, cleaning, and maintenance of the internal components of the detection chamber by operators. The detachable connection simplifies the maintenance process, allowing operators to quickly disassemble and replace components, reducing downtime. The hinge 15 connection and the detachable connection allow the device to be adjusted according to different installation environments and operational requirements, improving the device's adaptability. When maintenance or cleaning is required, the upper housing 71 can be easily opened, ensuring operator safety. After opening the upper housing 71, the internal condition of the detection chamber can be more clearly observed, facilitating problem diagnosis and leak detection. Because maintenance and component replacement are made easier, maintenance costs can be reduced.

[0045] In some embodiments, the other end of the upper shell 71 is provided with a third connecting hole, and the other end of the lower shell 72 is provided with a fourth connecting hole. The other ends of the upper shell 71 and the other ends of the lower shell 72 are connected by a second fastener 16 passing through the third connecting hole and the fourth connecting hole.

[0046] The upper shell 71 has a third connecting hole at one end, and the lower shell 72 has a fourth connecting hole at the other end. These holes ensure that the two shells can be precisely aligned and connected. The upper shell 71 and the lower shell 72 can be securely connected together by passing a second fastener 16 (such as a bolt, nut, etc.) through the third and fourth connecting holes.

[0047] The use of fasteners ensures a more secure connection between the upper housing 71 and the lower housing 72, improving the structural stability of the entire device and enabling it to withstand vibration and pressure in industrial environments. The connection holes and fasteners allow for quick assembly and disassembly of the upper housing 71 and lower housing 72, which is especially important for maintenance and component replacement. The fasteners provide uniform clamping force, ensuring no gaps between the upper housing 71 and lower housing 72, thereby improving sealing performance and preventing water and air bubble leakage. This design simplifies the housing structure, eliminating the need for complex welding or bonding processes and reducing production costs. The connection holes and fasteners can accommodate different materials, whether metal, plastic, or composite materials, enabling a secure connection. The fastener connection method reduces connection failures due to material fatigue or aging, improving the long-term reliability of the detection device.
