Description

Technical Field

[0001] This utility model relates to the field of civil gas equipment technology, and in particular to a natural gas equipment testing device. Background Technology

[0002] Testing natural gas equipment is a crucial step in ensuring its safe and efficient operation. Regulating valves within natural gas equipment are essential industrial devices that precisely control the flow and pressure of natural gas, ensuring its safe and efficient delivery.

[0003] A search revealed Chinese patent CN220932302U, which discloses a natural gas equipment testing device. The device includes a test bench with a connecting device and a pressing mechanism. An inlet pipe connects the inlet end of the connecting device to a high-pressure gas source, and an outlet pipe connects the outlet end of the connecting device to a pressure detection device. The pressing mechanism presses and fixes a pressure regulator onto the connecting device and seals it with its inlet and outlet ends for testing. This allows for the testing of the regulator's sealing and functional integrity before installation into a natural gas pipeline, and also presets the regulator's output pressure. This effectively simplifies the maintenance procedures for natural gas pipelines, shortens the time spent on gas outages during construction, and reduces the risk of gas leakage caused by live testing.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] While the aforementioned patent facilitates quick clamping of test components, its method of fixing and sealing the intersection through clamping and sealing gaskets is limited in its sealing effect. This can easily lead to unsatisfactory sealing at the joint, thus affecting the accuracy of the test results. Therefore, it has certain limitations. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a natural gas equipment testing device that, using a specially designed docking assembly, can effectively and accurately test devices such as regulating valves in natural gas equipment.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a natural gas equipment testing device, including a base, a pair of support seats fixedly installed on the surface of the base, a regulating valve being snapped into the interior of each support seat, a gas storage tank fixedly installed on one side of the base, a control board fixedly installed on the gas storage tank, two sets of limiting grooves fixedly opened on the base, and a docking assembly.

[0008] A docking assembly, the docking assembly including a support plate slidably mounted inside a limiting groove.

[0009] Preferably, a docking cylinder is fixedly installed on the support plate, a connecting pipe is fixedly installed on one side of the docking cylinder, the connecting pipe slides in fit with the inner wall of the air inlet end of the regulating valve, and multiple rubber rings are fixedly installed at equal intervals on the outer peripheral wall of the connecting pipe.

[0010] Preferably, one end of an adjacent pair of docking cylinders is fixedly connected to a flexible hose, wherein the ends of the pair of adjacent flexible hoses are respectively fixedly connected to an air inlet pipe, and the ends of the pair of flexible hoses near the air storage tank are respectively fixedly connected to an air outlet pipe, and control valves are respectively fixedly installed on the air inlet pipe and the air outlet pipe.

[0011] Preferably, a fixing column is fixedly installed between the air inlet pipe and the base, a support frame is fixedly installed between the bottom of a pair of adjacent air outlet pipes and the base, and a pressure and flow monitoring instrument is fixedly installed on each air outlet pipe.

[0012] Preferably, a pair of support rods are fixedly installed on the surface of the base located on one side of the docking cylinder. A sealing ring is fixedly installed at the end of each pair of support rods. A sealing rubber ring is fixedly installed on one side of the sealing ring. A sealing rubber sheet is fixedly installed on one side of the docking cylinder. The sealing rubber sheet slides in conjunction with the sealing rubber ring.

[0013] Preferably, a threaded rod is rotatably mounted on the bottom of the base, and a pair of sliders are threadedly connected to the threaded rod. Each slider is connected to a corresponding support plate on both sides via a connecting rod through a movable shaft, and a rotating handle is fixedly mounted on the end of the threaded rod.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] Firstly, this utility model, through its designed docking assembly, can effectively secure the two ends of the regulating valve. The docking pipe and rubber ring improve the sealing between the docking pipe and the two ports of the regulating valve, preventing air leakage and ensuring the accuracy of the test results. Furthermore, the sealing rubber ring and sealing rubber sheet further enhance the sealing effect at the connection of the docking assembly, thereby ensuring the accuracy of the test results for the regulating valve in the natural gas equipment.

[0016] Secondly, this utility model features a threaded rod that can be easily rotated using a handle. Through a connecting rod, the support plate and docking cylinder can be moved, facilitating the docking of the regulating valve. The included pressure and flow monitoring instrument can detect the regulating effect of the regulating valve on the pressure and flow inside the pipeline in real time, and the collected data is fed back to the control board, making it easier for staff to conduct intuitive testing and improving the convenience of testing.

[0017] This invention addresses the problem that while existing technologies can facilitate quick and easy clamping of test components, their method of fixing and sealing the intersection through clamping and sealing gaskets results in a single sealing effect, which can easily lead to unsatisfactory sealing at the joint and thus affect the accuracy of the test results.

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] This utility model provides an improved natural gas equipment testing device. The technical solution of this utility model is as follows:

[0028] like Figures 1-5As shown, a natural gas equipment testing device includes a base 1, a pair of support seats 2 fixedly installed on the surface of the base 1, a regulating valve 4 snapped into the interior of each support seat 2, a gas storage tank 20 fixedly installed on one side of the base 1, a control plate 21 fixedly installed on the gas storage tank 20, two sets of limiting grooves 3 fixedly opened on the base 1, and a docking assembly. The support seats 2 can provide stable support for the installation of the regulating valve 4, ensuring stability during the testing process, while the gas storage tank 20 can temporarily store the discharged natural gas, thus facilitating centralized processing later.

[0029] The docking assembly includes a support plate 7 that is slidably installed inside the limiting groove 3, and the support plate 7 can provide support for the docking assembly.

[0030] Furthermore, a docking cylinder 5 is fixedly installed on the support plate 7, and a connecting pipe 11 is fixedly installed on one side of the docking cylinder 5. The connecting pipe 11 slides in fit with the inner wall of the air inlet end of the regulating valve 4. Multiple rubber rings 12 are fixedly installed at equal intervals on the outer peripheral wall of the connecting pipe 11. The rubber rings 12 can improve the airtightness between the connecting pipe 11 and the inside of the regulating valve 4, thereby improving the accuracy of the test results.

[0031] Furthermore, one end of each pair of adjacent docking cylinders 5 is fixedly connected to a hose 6, and the ends of each pair of adjacent hoses 6 are respectively fixedly connected to an inlet pipe 15. The ends of the pair of hoses 6 near the gas storage tank 20 are respectively fixedly connected to an outlet pipe 16. Control valves 19 are respectively fixedly installed on the inlet pipe 15 and the outlet pipe 16. The hoses 6 not only ensure the normal input and output of natural gas, but also do not hinder the movement of the docking cylinders 5.

[0032] As a further embodiment of this utility model, a fixing column 22 is fixedly installed between the air inlet pipe 15 and the base 1, and a support frame 17 is fixedly installed between the bottom of a pair of adjacent air outlet pipes 16 and the base 1. A pressure and flow monitoring instrument 18 is fixedly installed on each air outlet pipe 16. The pressure and flow monitoring instrument 18 facilitates real-time detection of the pressure and flow of the internal pipes.

[0033] Furthermore, a pair of support rods 25 are fixedly installed on the surface of the base 1 located on one side of the docking cylinder 5. A sealing ring 24 is fixedly installed at the end of each pair of support rods 25. A sealing rubber ring 23 is fixedly installed on one side of the sealing ring 24, and a sealing rubber sheet 13 is fixedly installed on one side of the docking cylinder 5. The sealing rubber sheet 13 and the sealing rubber ring 23 slide together internally. The sealing rubber sheet 13 and the sealing rubber ring 23 can further improve the sealing effect at the docking point, thereby avoiding affecting the accuracy of the test of the regulating valve 4. The sealing ring 24 is composed of two semi-arc components. The two semi-arc components form the sealing ring 24. One side is rotatably connected by a movable shaft, and the other side is fixed by a fixing bolt, which facilitates the installation of the regulating valve 4.

[0034] Furthermore, a threaded rod 10 is rotatably mounted on the bottom of the base 1. A pair of sliders 9 are threadedly connected to the threaded rod 10. Each slider 9 is connected to a corresponding support plate 7 on both sides via a connecting rod 8 through a movable shaft. A rotating handle 14 is fixedly mounted on the end of the threaded rod 10. By rotating the threaded rod 10 with the rotating handle 14, the slider 9 is moved. The connecting rod 8 moves the support plate 7, which in turn moves the docking cylinder 5, thus achieving the docking effect with the regulating valve 4.

[0035] The specific working method is as follows: Open the sealing ring 24, install the regulating valve 4 to be tested on the corresponding support 2, close the sealing ring 24, and fix it with the fixing bolts. Then, rotate the handle 14 to rotate the threaded rod 10, and then use the slider 9 and connecting rod 8 to move the support plate 7, and then move the docking cylinder 5 to achieve the snap-fit ​​between the two ends of the regulating valve 4. After opening all the control valves 19, natural gas is introduced. The relevant test data of the regulating valve 4 are measured by the regulating effect of the regulating valve 4. The internal pressure and flow data are detected in real time by the pressure and flow monitoring instrument 18, so as to facilitate the acquisition of test data. The sealing rubber ring 23 and sealing rubber sheet 13 can improve the airtightness of the docking point, thereby improving the accuracy of the test results.

[0036] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
