Technical Field

[0001] The utility model relates to a hot-opening test port device, belonging to the technical field of ventilation duct monitoring. Background Technique

[0002] In various buildings and industrial facilities, ventilation ducts play a crucial role. They are responsible for regulating and maintaining indoor air quality to ensure the safety and comfort of personnel. However, the gas state inside these ventilation ducts, such as temperature, humidity, flow rate, and possible pollutant content, are all key factors affecting their performance. Therefore, it is particularly important to regularly test and monitor the gas inside the ventilation ducts.

[0003] Traditional methods for testing the gas in ventilation ducts usually require setting up special interfaces or valves on the ducts. This not only increases the complexity of the system, making the monitoring work of ventilation ducts cumbersome, but also may damage the sealing of the ducts due to frequent disassembly and installation, resulting in the risk of gas leakage. For this reason, a hot-opening test port device is proposed. Content of the Utility Model

When it is necessary to install a monitoring instrument inside the ventilation duct, rotate the threaded plug to take it out from the inside of the sleeve, and then the instrument can be sent into the ventilation duct through the sleeve and the second through hole to complete the monitoring work. Through the special pipe wall opening structure, it is possible to facilitate the user to perform gas testing operations while maintaining the sealing of the ventilation duct.

The opening assembly 20 includes a limit block 21, a second through hole 22, a sealing ring 23, a sleeve 24, an external thread 25, an internal thread 26, a nut 27, and a threaded plug 28;

[0028] One end of the limit block 21 is provided with a second through hole 22. One end of the limit block 21 is fixedly connected with a sleeve 24. The sleeve 24 is of a hollow internal structure. The second through hole 22 communicates with the sleeve 24. A sealing ring 23 is sleeved on the outer side wall of the sleeve 24. The sealing ring 23 is arranged on the front surface of the limit block 21. An external thread 25 is arranged on the outer side wall of the sleeve 24. A nut 27 is threadedly connected to the outer side wall of the sleeve 24. An internal thread 26 is arranged on the inner side wall of the sleeve 24. A threaded plug 28 is threadedly connected to the inner side wall of the sleeve 24. When it is necessary to install a monitoring instrument inside the ventilation duct 11, rotate the threaded plug 28 to take it out from the inside of the sleeve 24, and then the instrument can be sent into the ventilation duct 11 through the sleeve 24 and the second through hole 22 to complete the monitoring work. Through the special pipe wall opening structure, while maintaining the airtightness of the ventilation duct 11, it is convenient for users to perform gas test operations. The sealing ring 23 is made of fluororubber, which has good high-temperature resistance and high chemical stability, and can maintain stable performance when contacting corrosive media. Sealing the connection between the device and the pipeline through the fluororubber sealing ring can better adapt to the acidic or alkaline environment of the process exhaust system, extend the service life of the hot open test port, and at the same time provide a good sealing effect.

[0029] In this embodiment, specifically: The opening assembly 20 further includes a limit plate 29. The front surface of the threaded plug 28 is fixedly connected with the limit plate 29. The limit plate 29 is of a regular polygon structure, which is convenient for the staff to manually rotate the threaded plug 28.

[0030] In this embodiment, specifically: The opening assembly 20 further includes a hot open test port indicating rod 210. The front surface of the limit plate 29 is fixedly connected with the hot open test port indicating rod 210.

[0033] In this embodiment, specifically: One end of the sleeve 24 penetrates through the first through hole 12 and extends to the outside of the ventilation duct 11. During installation, the sleeve 24 is passed through the first through hole 12 until the sealing ring 23 contacts the inner side wall of the ventilation duct 11.

[0034] In this embodiment, specifically: The top and bottom ends of the ventilation duct 11 are symmetrically and fixedly connected with connecting flanges 13. The connecting flanges 13 are used to connect the ventilation duct 11 to other pipelines.

Then the nut 27 is threadedly connected to the outer side wall of the sleeve 24. The nut 27 is rotated by a wrench. During the movement of the nut 27, the sealing ring 23 is gradually in close fit with the inner side wall of the ventilation duct 11 to form a sealing structure to prevent the ventilation duct 11 from leaking. After the nut 27 is installed, the threaded plug 28 is threadedly connected to the inner side wall of the sleeve 24. When it is necessary to install a monitoring instrument into the ventilation duct 11, the threaded plug 28 is rotated to remove it from the inside of the sleeve 24, and then the instrument can be passed through the sleeve 24 and the second through hole 22 into the ventilation duct 11 to complete the monitoring work. Through the special pipe wall opening structure, while maintaining the sealing performance of the ventilation duct 11, it is convenient for users to perform gas testing operations.
