Description

Technical Field

[0001] This utility model relates to the technical field of fluid pipeline observation equipment, and more specifically, to a ferrule-type direct-through sight glass. Background Technology

[0002] In fluid pipeline systems, straight-through sight glasses are important devices used to observe the flow state, color, and impurities of the medium inside the pipeline. They are widely used in chemical, petroleum, and other industrial fields. They are connected to the pipeline through a viewing window to achieve real-time monitoring, and their structural design directly affects the performance of the equipment.

[0003] Existing straight-through sight glasses have the following technical problems in practical use: Firstly, their sealing structure design is not reasonable enough. Most use flat sealing gaskets, which are prone to uneven stress when tightening bolts, resulting in poor sealing performance. This is especially true in high-pressure or vibrating working environments, where the risk of media leakage is high. Secondly, installation and maintenance are inconvenient. The connection structure between the sight glass and the pipeline is relatively complex and lacks standardized design, making disassembly and assembly difficult, time-consuming, and labor-intensive. Moreover, some parts have smooth surfaces, making it difficult to apply force during disassembly and easily causing damage to the parts. In addition, existing straight-through sight glasses are also insufficient in terms of protection. They lack effective protective devices on the sides, failing to effectively prevent interference and damage from external objects to the observation window, affecting the observation effect. At the same time, their structure is also lacking in impact resistance, making them easily damaged by external collisions. Utility Model Content

[0004] In view of this, this utility model proposes a ferrule-type direct-viewing lens to address the shortcomings of the existing technology and solve the above-mentioned problems.

[0005] This utility model provides a ferrule-type direct-viewing lens, comprising:

[0006] The system comprises an observation module, a fixing module, and a protection module, with the observation module and protection module connected via the fixing module. The observation module includes: a first retaining nut, a second retaining nut, a first sight glass body, a second sight glass body, and a hollow glass cylinder. The first retaining nut is connected to the first sight glass body, and the second retaining nut is connected to the second sight glass body. The hollow glass cylinder is disposed between the first and second sight glass bodies. The protection module includes: a first sealing gasket, a second sealing gasket, and a blocking device. The first sealing gasket is disposed between the hollow glass cylinder and the first sight glass body, and the second sealing gasket is disposed between the hollow glass cylinder and the second sight glass body.

The internal thread sections are respectively connected to the first sight glass body and the second sight glass body, and the connection ports are used to connect to the working pipe.

[0008] Furthermore, both the first and second viewing mirror bodies are provided with an external threaded section, a support column, and a base connected in sequence, and the base is connected to the fixing module.

[0009] Furthermore, the fixing module includes: a double-ended bolt, a first positioning hole and a positioning pin, wherein the two ends of the double-ended bolt pass through the base of the first sight glass body and the second sight glass body respectively, and the first positioning hole is disposed on the side of the base.

[0010] Furthermore, the first viewing mirror body is provided with a first viewing mirror channel, and the second viewing mirror body is provided with a second viewing mirror channel, the first viewing mirror channel and the second viewing mirror channel being matched with the aperture of the hollow glass cylinder.

[0011] Furthermore, both the first viewing mirror channel and the second viewing mirror channel are provided with a connecting chamber, which is located at the external thread section.

[0012] Furthermore, the barrier device is provided with a barrier plate and a barrier net. There are two barrier plates, and the barrier net is connected to the barrier plate. The barrier plate is connected to the first viewing mirror body and the second viewing mirror body. The barrier net is located around the circumference of the hollow glass cylinder.

[0013] Furthermore, the barrier plate is provided with a second positioning hole, and a positioning pin is installed in the second positioning hole. The positioning pin is cylindrical.

[0014] Furthermore, the side of the support column is provided with a clamping surface, which is used to facilitate disassembly and assembly.

[0015] Furthermore, the first sealing gasket and the second sealing gasket have a stepped structure.

[0016] Compared with the prior art, the advantages of this utility model are as follows: Through modular design, the observation module, fixing module and protection module are organically combined. The first and second ferrule nuts of the observation module are connected to the first and second sight glasses, and together with the hollow glass cylinder, they achieve stable installation and clear observation. The first and second sealing gaskets of the protection module are set between the hollow glass cylinder and the first and second sight glasses, which can effectively fill the components, distribute the force evenly, and prevent media leakage. The side barrier device can block foreign objects and buffer impact. The fixing module ensures that each component is axially tightened and circumferentially positioned. This structure not only achieves reliable sealing, stable installation and efficient protection, but also makes the overall structure compact due to the modular design, saving space and facilitating disassembly and maintenance. It effectively solves the problems of poor sealing performance, inconvenient installation and insufficient protection in the prior art. Attached Figure Description

[0030] like Figure 1-8 As shown, a preferred embodiment of the present invention provides a ferrule-type direct-viewing lens, comprising:

[0031] The system comprises an observation module, a fixing module, and a protection module, with the observation module and protection module connected via the fixing module. The observation module includes: a first ferrule nut 90, a second ferrule nut 910, a first viewing mirror body 10, a second viewing mirror body 20, and a hollow glass cylinder 50. The first ferrule nut 90 is connected to the first viewing mirror body 10, and the second ferrule nut 910 is connected to the second viewing mirror body 20. The hollow glass cylinder 50 is positioned between the first viewing mirror body 10 and the second viewing mirror body 20. The protection module includes: a first sealing gasket 30, a second sealing gasket 40, and a blocking device 70. The first sealing gasket 30 is positioned between the hollow glass cylinder 50 and the first viewing mirror body 10, the second sealing gasket 40 is positioned between the hollow glass cylinder 50 and the second viewing mirror body 20, and the blocking device 70 is positioned on the side of the first viewing mirror body 10 and the second viewing mirror body 20.

[0032] It should be noted that this ferrule-type through-viewing scope adopts a modular design, consisting of an observation module, a fixing module, and a protection module. The observation module is connected to the protection module through the fixing module. The observation module includes a first ferrule nut 90, a second ferrule nut 910, a first viewing scope body 10, a second viewing scope body 20, and a hollow glass cylinder 50. The first ferrule nut 90 is connected to the first viewing scope body 10, and the second ferrule nut 910 is connected to the second viewing scope body 20. The hollow glass cylinder 50 is positioned between the first viewing scope body 10 and the second viewing scope body 20 to achieve a stable connection and clear observation. The protection module is equipped with a first sealing gasket 30, a second sealing gasket 40, and a blocking device 70. The inner surfaces of the first sealing gasket 30 and the second sealing gasket 40 are provided with hollow areas to expand the locking safety range. A first sealing gasket 30 is disposed between the hollow glass cylinder 50 and the first sight glass body 10, and a second sealing gasket 40 is disposed between the hollow glass cylinder 50 and the second sight glass body 20. A barrier device 70 is disposed on the sides of the first sight glass body 10 and the second sight glass body 20, effectively preventing media leakage and external interference. This structural design gives the ferrule-type straight-through sight glass excellent sealing performance, durability, and visibility. It not only allows for precise observation of the internal media flow but also adapts to various complex operating conditions, extending service life, reducing maintenance costs, and improving the safety and reliability of equipment operation.

[0033] In some embodiments of this application, both the first ferrule nut 90 and the second ferrule nut 910 are provided with an internal thread section 902 and a connection port 901. The internal thread section 902 is connected to the first sight glass body 10 and the second sight glass body 20 respectively, and the connection port 901 is used to connect the working pipe.

[0034] It should be noted that both the first ferrule nut 90 and the second ferrule nut 910 are provided with an internal thread section 902 and a connection port 901. The internal thread section 902 connects to the first sight glass body 10 and the second sight glass body 20 respectively, forming a stable mechanical connection structure to ensure the overall stability of the observation module. The connection port 901 is used to connect to the working pipeline, realizing seamless docking between the ferrule straight-through sight glass and the working system. This design not only ensures reliable installation of the sight glass in the piping system, but also facilitates disassembly and maintenance through the threaded connection. At the same time, the standardized design of the connection port 901 enhances compatibility with working pipelines of different specifications, further improving the practicality and applicability of the ferrule straight-through sight glass and meeting diverse industrial application needs.

[0035] In some embodiments of this application, both the first viewing mirror body 10 and the second viewing mirror body 20 are provided with an external threaded section 801, a support column 802 and a base 803 connected in sequence, and the base 803 is connected to the fixing module.

[0036] It should be noted that both the first viewing mirror body 10 and the second viewing mirror body 20 are provided with an external threaded section 801, a support column 802, and a base 803 connected in sequence. The external threaded section 801 cooperates with the internal threaded sections 902 of the first ferrule nut 90 and the second ferrule nut 910 to achieve a stable connection of the observation module. The support column 802 provides positioning and support for the hollow glass cylinder 50, ensuring its stability during the flow of the medium. The base 803 is connected to the fixing module, further enhancing the overall fixing effect of the first viewing mirror body 10 and the second viewing mirror body 20 in the ferrule through-viewing mirror. This segmented structural design not only optimizes the mechanical properties of the first viewing mirror body 10 and the second viewing mirror body 20, enabling them to withstand higher pressure and impact, but also improves the interchangeability and assembly efficiency between components through the threaded connection and the base 803 interface, reducing production and maintenance costs, while ensuring the reliability and sealing of the ferrule through-viewing mirror during long-term use.

[0037] In some embodiments of this application, the fixing module includes: a double-ended bolt 60, a first positioning hole 8031 ​​and a positioning pin 702. The two ends of the double-ended bolt 60 pass through the base 803 of the first viewing mirror body 10 and the second viewing mirror body 20 respectively. The first positioning hole 8031 ​​is provided on the side of the base 803.

[0038] It should be noted that the fixing module includes a double-ended bolt 60, a first positioning hole 8031 ​​and a positioning pin 702. The two ends of the double-ended bolt 60 pass through the base 803 of the first sight glass body 10 and the second sight glass body 20 respectively to achieve axial fastening connection, ensuring that the hollow glass cylinder 50 is stably clamped and resists the axial force and vibration generated by the flow of the medium, ensuring assembly accuracy, improving the deformation resistance under complex working conditions, extending the service life of the ferrule through sight glass and simplifying the maintenance and disassembly process.

[0039] In some embodiments of this application, the first viewing mirror body 10 is provided with a first viewing mirror channel 101, and the second viewing mirror body 20 is provided with a second viewing mirror channel 201. The first viewing mirror channel 101 and the second viewing mirror channel 201 are matched with the aperture of the hollow glass cylinder 50.

[0040] It should be noted that the first sight glass body 10 is provided with a first sight glass channel 101, and the second sight glass body 20 is provided with a second sight glass channel 201. The apertures of the first sight glass channel 101 and the second sight glass channel 201 are matched with the aperture of the hollow glass cylinder 50. This design allows the medium to pass smoothly through the through path formed by the first sight glass channel 101, the hollow glass cylinder 50, and the second sight glass channel 201, avoiding abrupt changes in the flow path or medium stagnation caused by aperture differences. At the same time, aperture matching ensures the consistency of the field of view, allowing operators to clearly observe the flow state, color changes, or impurities of the medium in the entire channel through the hollow glass cylinder 50. The coaxial design of the channel structure can also reduce fluid resistance and pressure loss, improve the hydrodynamic performance of the ferrule straight-through sight glass in the pipeline system, and the standardized aperture matching also facilitates the assembly and alignment of various components, ensures uniform pressure on the sealing gasket, and further enhances the sealing performance and reliability of the device.

[0041] In some embodiments of this application, both the first viewing mirror channel 101 and the second viewing mirror channel 201 are provided with a connecting chamber 100, which is located at the external thread section 801.

[0042] It should be noted that both the first sight glass channel 101 and the second sight glass channel 201 have a connecting chamber 100 at the external thread section 801. This design optimizes the structural connection and media flow performance. The connecting chamber 100 widens the local inner diameter of the channel, which can buffer the pressure fluctuations caused by the sudden change in cross-section when the media flows through the thread section, reduce fluid resistance and eddy currents, and ensure smooth media flow. It also facilitates the docking of the observation module and the working pipeline, reduces assembly difficulty, and improves the adaptability and reliability of the ferrule straight-through sight glass under complex working conditions.

[0043] In some embodiments of this application, the blocking device 70 is provided with a blocking plate 704 and a blocking net 701. There are two blocking plates 704. The blocking net 701 is connected to the blocking plate 704. The blocking plate 704 is connected to the first viewing mirror body 10 and the second viewing mirror body 20. The blocking net 701 is disposed in the circumference of the hollow glass cylinder 50.

[0044] It should be noted that the barrier device 70 adopts a composite structure design of "barrier plate 704 + barrier mesh 701". Two barrier plates 704 are symmetrically distributed on the side of the ferrule-mounted sight glass, connected to the barrier mesh 701 to form a three-dimensional protective system. This design effectively blocks the intrusion of foreign objects, preventing them from scratching the hollow glass cylinder 50 and affecting the observation effect. Simultaneously, the barrier plates 704 buffer external impacts, improving the sight glass's resistance to external forces. The perforated structure of the barrier mesh 701 ensures timely dissipation of heat generated by the medium flow while maintaining protective strength, preventing localized temperature accumulation that could affect the sight glass's performance, and does not interfere with the observation module's real-time monitoring of the internal medium's state. This combined barrier device 70 enhances the environmental adaptability and durability of the ferrule-mounted sight glass, providing multiple guarantees for the stable operation of the equipment.

[0045] In some embodiments of this application, the barrier plate 704 is provided with a second positioning hole 703, and a positioning pin 702 is installed in the second positioning hole 703. The positioning pin 702 is cylindrical.

[0046] It should be noted that the barrier plate 704 is provided with a second positioning hole 703, which is precisely aligned and fixed with the first positioning hole 8031 ​​on the side of the sight glass body base 803 through a cylindrical positioning pin 702, thereby completing the reliable installation of the barrier device 70. This design, through the tight fit between the positioning pin 702 and the positioning hole, ensures the relative positional accuracy between the barrier plate 704 and the sight glass body base 803, preventing the barrier device 70 from shifting or loosening under vibration or external force, thus effectively maintaining its barrier function against foreign objects; at the same time, the cylindrical positioning pin 702 facilitates assembly operations, reduces installation difficulty, and provides uniform circumferential constraint, enhancing the stability and fatigue resistance of the connection parts, further improving the reliability and service life of the overall structure of the ferrule through-sight glass.

[0047] In some embodiments of this application, the side of the support column 802 is provided with a clamping plane 8021, which is used to facilitate disassembly and assembly.

[0048] It should be noted that the clamping surface 8021 on the side of the support column 802 facilitates the assembly and disassembly of the ferrule-type straight-through sight glass. During assembly, maintenance personnel can use tools to hold the clamping surface 8021, improving assembly efficiency; during disassembly, the clamping surface 8021 provides a stable force application point, avoiding surface damage to components caused by manual operation. It also allows for quick disassembly with specialized tools, reducing the risk of misoperation due to inconvenient operation. Furthermore, this design effectively solves the problem of the smooth surface of the cylindrical support column 802, making it difficult to apply force, reducing maintenance difficulty and shortening repair time. This is of great significance for ensuring the long-term stable operation of the ferrule-type straight-through sight glass and reducing maintenance costs.

[0049] In some embodiments of this application, the first sealing gasket 30 and the second sealing gasket 40 have a stepped structure.

[0050] It should be noted that the first sealing gasket 30 and the second sealing gasket 40 adopt a stepped structure design, which significantly improves the sealing performance and compatibility of the ferrule-type direct-through sight glass. The stepped structure can precisely match the connection interface between the insulating glass cylinder 50 and the sight glass body, effectively filling the small tolerances between components and enhancing the ability to prevent media leakage. At the same time, the stepped design makes the sealing gasket more evenly stressed when the double-ended bolt 60 is tightened, avoiding the local compression deformation or stress concentration problems that may occur with traditional flat gaskets, making it particularly suitable for high-pressure or vibrating working environments. In addition, this structure can also assist in the positioning and installation of the insulating glass cylinder 50, ensuring its coaxiality with the first sight glass channel 101 and the second sight glass channel 201, further optimizing the field of view and fluid flow path. This stepped sealing gasket design not only improves the sealing performance of the device, but also enhances the reliability and durability of the overall structure.

[0051] The working process of this utility model is as follows: During installation, the first sealing gasket 30 is placed between the hollow glass cylinder 50 and the first sight glass body 10, and the second sealing gasket 40 is placed between the hollow glass cylinder 50 and the second sight glass body 20. The internal thread section 902 of the first ferrule nut 90 is connected to the external thread section 801 of the first sight glass body 10, and the internal thread section 902 of the second ferrule nut 910 is connected to the external thread section 801 of the second sight glass body 20, thus completing the assembly of the observation module; the double-ended bolt 60 passes through the first... The base 803 of the sight glass body 10 and the second sight glass body 20, with the positioning pin 702 inserted into the first positioning hole 8031 ​​on the side of the base 803 and the second positioning hole 703 on the barrier plate 704, fix the protection module and the observation module, and simultaneously achieve axial fastening and circumferential positioning of each component. Subsequently, the connection port 901 of the first ferrule nut 90 and the second ferrule nut 910 is connected to the working pipe, so that the first sight glass channel 101, the hollow glass cylinder 50, and the second sight glass channel 201 form a medium flow path. During operation, the medium flows into the sight glass channel through the working pipe, and the operator can clearly observe the changes in the color, flow rate, and state of the medium through the hollow glass cylinder 50. The stepped sealing gasket can effectively prevent medium leakage, and the side barrier device 70, through the barrier plate 704 and the barrier net 701, blocks the intrusion of external foreign objects and protects the observation module. When maintenance is required, the clamping plane 8021 on the side of the support column 802 can be used with tools to easily disassemble the relevant parts for inspection or replacement, ensuring the continuous and stable operation of the ferrule through-view mirror.
