[0002] Natural gas, an indispensable energy source in modern life, is widely used in residential, commercial buildings, and industrial production. Its safe and stable transmission is directly related to the safety of life and property and the orderly conduct of daily life and production. The safe operation of gas pipelines is the core prerequisite for ensuring the use of gas, and the safety inspection of gas pipelines is a key task throughout the entire process of pipeline installation, maintenance, and repair.

[0003] Most existing gas pipeline flow measurement fixtures do not integrate dedicated temperature and pressure monitoring interfaces. Temperature and pressure sensors can only be installed by branching through hoses or modifying the pipeline. This is not only cumbersome to install and prone to causing gas leaks, but the branched pipelines can also interfere with the stability of airflow, resulting in inaccurate temperature and pressure data acquisition. In addition, the connection method between the fixture and the existing gas pipeline is complicated and has poor compatibility, making it impossible to quickly achieve test deployment.

[0004] Therefore, a quick-connect gas pipeline test connector is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a quick-connect gas pipeline test connector, which effectively solves the problems of cumbersome tooling and poor compatibility in connecting existing tools and pipelines, significantly improves test deployment efficiency, eliminates the risk of leakage and airflow interference caused by additional pipeline modifications, ensures the accuracy of temperature and pressure data acquisition, and provides reliable parameter support for comparing gas flow measurement data under different pressure and temperature conditions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect gas pipeline test connector, comprising a test connector body, a test interface seat mounted on the outer surface of the test connector body, a temperature sensor interface at one end of the test interface seat, a pressure sensor interface on the outer surface of the test interface seat, internal threads engraved on the inner surfaces of both the pressure sensor interface and the temperature sensor interface, the pressure sensor interface being used to install a pressure sensor connector via the internal thread, the temperature sensor interface being used to install a temperature sensor connector via the internal thread, and quick-release connectors at both ends of the test connector body.

[0010] The second connector includes two snap-fit ​​strips fixedly connected to the second connector, and two snap-fit ​​sleeves are respectively sleeved with the two snap-fit ​​strips. Two snap-fit ​​sleeves are fixedly connected to the outer surface of the second connector, and the two snap-fit ​​sleeves are respectively sleeved with the two snap-fit ​​strips.

[0011] Preferably, each of the two snap-fit ​​strips has several protrusions fixedly connected to one end of each of the snap-fit ​​strips, and the inner surfaces of the snap-fit ​​sleeves are provided with grooves that cooperate with the protrusions.

[0029] 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.

[0030] like Figures 1 to 5As shown, this utility model provides a quick-connect gas pipeline test connector, including a test connector body 1. A test interface seat 2 is installed on the outer surface of the test connector body 1. A temperature sensor interface 22 is provided at one end of the test interface seat 2, and a pressure sensor interface 21 is provided on the outer surface of the test interface seat 2. The inner surfaces of the pressure sensor interface 21 and the temperature sensor interface 22 are both engraved with internal threads. The pressure sensor interface 21 is used to install the pressure sensor connector through the internal thread, and the temperature sensor interface 22 is used to install the temperature sensor connector through the internal thread. Quick-release connectors 3 are provided at both ends of the test connector body 1. Through the integrated design of the test interface seat 2, pressure sensor interface 21, temperature sensor interface 22 and quick-release connectors 3 in the test connector body 1, gas pipeline connection and temperature and pressure data acquisition can be realized simultaneously without the need to build an additional test pipeline, simplifying the overall structure of the test system and improving the convenience of test deployment.

[0031] Specifically, the test interface seat 2 is connected to the test connector body 1, and the test interface seat 2 and the test connector body 1 are integrally formed structures. The integrally formed and connected structure of the test interface seat 2 and the test connector body 1 eliminates the gap hazards caused by separate assembly. This not only enhances the structural stability of the test interface seat 2, but also ensures the sealing of the gas flow path, avoiding the impact of gas leakage on the accuracy of data during temperature and pressure testing.

[0032] like Figures 1 to 5 As shown, the quick-release connector 3 includes a connector 31 and a connector 32 that are connected to each other. The connector 31 is rotatably connected to the test connector body 1, and the gas pipeline body 33 is fixedly sleeved on the inner surface of the connector 32.

[0033] The connector 31 includes two snap-fit ​​strips 312 that are fixedly connected to the outer surface of the connector 31, and two snap-fit ​​sleeves 311 that are fixedly connected to the outer surface of the connector 31.

[0034] Connector 2 32 includes two snap-fit ​​strips 2 322 fixedly connected to connector 2 32, two snap-fit ​​sleeves 1 311 respectively sleeved with the two snap-fit ​​strips 2 322, and two snap-fit ​​sleeves 2 321 fixedly connected to the outer surface of connector 2 32. The two snap-fit ​​sleeves 2 321 respectively sleeved with the two snap-fit ​​strips 1 312. The quick-release connector 3 achieves quick alignment and connection of connector 1 31 and connector 2 32 through the rotational connection of connector 1 31 and connector 2 32, and the cross-sleeving structure of snap-fit ​​strips 1 312, snap-fit ​​strips 2 322 and snap-fit ​​sleeves 1 311, snap-fit ​​sleeves 2 321, without the need for complicated alignment operations, which greatly reduces the difficulty of gas pipeline docking.

[0035] Furthermore, several protrusions 314 are fixedly connected to one end of the snap-fit ​​strip 312 and the snap-fit ​​strip 322 on opposite sides. The inner surfaces of the snap-fit ​​sleeve 311 and the snap-fit ​​sleeve 321 are provided with grooves 313 that cooperate with the protrusions 314. By setting protrusions 314 on the snap-fit ​​strip 312 and the snap-fit ​​strip 322, and providing matching grooves 313 in the snap-fit ​​sleeve 311 and the snap-fit ​​sleeve 321, the snap-fit ​​strip and the snap-fit ​​sleeve are fitted together to form a positioning engagement, which avoids relative sliding after docking and improves the stability of the quick-release connector 3 connection.

[0036] like Figures 1 to 5 As shown, both the groove 313 and the protrusion 314 are hemispherical, and the protrusion 314 is made of elastic rubber. The hemispherical structure makes it easy for the protrusion 314 to smoothly enter or exit the groove 313. The elastic material can compensate for the gap through deformation, which not only ensures the convenience of disassembly and assembly, but also enhances the tightness of engagement.

[0037] It is worth noting that the corresponding ends of connector 1 31 and connector 2 32 are provided with a sealing ring 34. Both the upper and lower ends of the sealing ring 34 are fixedly connected with retaining rings 341. The corresponding ends of connector 1 31 and connector 2 32 are fixedly connected with annular grooves 35 that cooperate with retaining rings 341. The sealing ring 34 is set between connector 1 31 and connector 2 32, and the positioning and installation of the sealing ring 34 is achieved by the cooperation of retaining ring 341 and annular groove 35, which effectively prevents gas from leaking from the mating surface of connector 1 31 and connector 2 32, and improves the sealing performance of quick-release connector 3.

[0038] like Figures 1 to 5 As shown, the retaining ring 341 and the sealing ring 34 are integrally formed, and the retaining ring 341 and the annular groove 35 are connected by an interference fit. The integrally formed structure avoids the risk of the retaining ring 341 and the sealing ring 34 falling off, while the interference fit ensures the fixing effect of the retaining ring 341 in the annular groove 35, further enhancing the sealing reliability of the sealing ring 34.

[0039] Working principle and process: In use, first, fix the gas pipeline body 33 onto the inner surface of connector 2 32. Then, align connector 1 31 with connector 2 32 and rotate connector 1 31 so that snap-fit ​​strip 1 312 cross-fits snap-fit ​​sleeve 2 321 and snap-fit ​​strip 2 322 cross-fits snap-fit ​​sleeve 1 311. At the same time, the hemispherical protrusion 314 of elastic rubber material deforms under compression and snaps into the corresponding groove 313, completing the quick fixation of quick-release connector 3. At this time, the retaining rings 341 at both ends of the sealing ring 34 are interference-fitted with the annular grooves 35 of connector 1 31 and connector 2 32 to achieve sealing of the mating surface. During testing, install the corresponding sensor connectors through the internal threads of pressure sensor interface 21 and temperature sensor interface 22 respectively. The sensors collect pressure and temperature data in the gas pipeline in real time through the test interface seat 2 connected to the test connector body 1.
