Description

Technical Field

[0001] This application relates to the field of fluid pipeline pressure testing technology, and in particular to a multifunctional pipeline pressure testing fixture. Background Technology

[0002] Traditional pipeline pressure testing equipment typically only supports single-path testing, requiring repeated disassembly and reassembly of the equipment to meet different pressure level requirements. This is inefficient and carries the risk of seal failure. When testing multiple pipelines, multiple independent sets of equipment are required, which occupy a large space and are complex to operate.

[0003] Therefore, there is an urgent need for an integrated chemical apparatus that can control multiple pressures in parallel and support differentiated testing. Utility Model Content

[0004] To address or partially address the problems existing in related technologies, this application provides a multifunctional pipeline pressure testing fixture that enables simultaneous independent pressure regulation and monitoring of multiple pipelines under a single air source input, thereby improving testing efficiency and safety.

[0005] This application provides a multifunctional pipeline pressure testing fixture, including a main pipeline 2, which is connected to a pump station 1. A main pipeline valve 8 is installed on the main pipeline 2, and a diversion device 3 is installed at the end of the main pipeline 2. The diversion device 3 is provided with at least two branch joints, and branch pipelines 4 are installed on the branch joints respectively. A branch regulating valve 5 is installed on the branch pipelines 4, and quick connectors 9 of different diameters are connected to the ends of the branch pipelines 4. A branch pressure relief valve 10 is connected to the quick connectors 9.

[0006] Optionally, in some embodiments, a main pipeline safety valve 7 is also installed on the main pipeline 2, and the main pipeline safety valve 7 is located between the pump station 1 and the main pipeline valve 8.

[0007] Optionally, in some embodiments, branch pressure gauges 6 with different ranges are installed on the branch pipes 4.

[0008] The technical solution provided in this application may include the following beneficial effects: This application connects to a pressure source via a main pipeline, and then distributes the flow to multiple independent branches via a multi-port structure. Each branch is equipped with a pressure regulating valve, pressure gauge, and pressure relief valve, enabling a single device to simultaneously conduct tests of different pressure levels on multiple pipelines. This solves the problems of low efficiency and complicated operation of traditional tooling, and significantly improves testing safety and economy.

[0017] To address the aforementioned issues, this application provides a multifunctional pipeline pressure testing fixture that enables simultaneous independent pressure regulation and monitoring of multiple pipelines under a single air source input, thereby improving testing efficiency and safety.

[0018] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0019] See Figure 1 The multi-functional pipeline pressure testing fixture includes a main pipeline 2, which is connected to a pump station 1. A main pipeline valve 8 is installed on the main pipeline 2. A diversion device 3 is installed at the end of the main pipeline 2. The diversion device 3 is provided with at least two branch joints. Branch pipelines 4 are installed on the branch joints respectively. Branch regulating valves 5 are installed on the branch pipelines 4. Quick connectors 9 of different diameters are connected to the ends of the branch pipelines 4. Branch pressure relief valves 10 are connected to the quick connectors 9.

[0020] In some embodiments, a main pipeline safety valve 7 is also installed on the main pipeline 2, and the main pipeline safety valve 7 is located between the pump station 1 and the main pipeline valve 8.

[0021] In some embodiments, branch pressure gauges 6 with different ranges are installed on the branch pipes 4 respectively.

[0022] The main pipeline 2 connects to the external pressure source pump station 1 and is equipped with a main pipeline valve 8, including a multi-branch system: N parallel branch pipelines 4 (N≥2), each branch includes: a branch regulating valve 5, which independently controls the branch output pressure, a branch pressure gauge 6, which monitors the branch pressure in real time, and a quick connector 9, which adapts to the test pipeline with different pipe diameters; and a safety control system: a main pipeline safety valve 7, which automatically releases overpressure, and a branch pressure relief valve 10, which independently releases pressure on a single line.

[0023] This application features multi-channel independent pressure regulation: differentiated pressure output (e.g., branch 1: 0.5MPa, branch 2: 2.0MPa) is achieved through branch pressure regulating valves; parallel testing: multiple pipelines at different levels can be tested simultaneously with a single fixture, reducing equipment switching; integrated safety design: a main / branch dual-stage pressure relief mechanism avoids the risk of overpressure.

[0024] During implementation, taking a three-way system as an example, connect the pipelines to be tested: connect the three pipelines to be tested to quick connectors Q1, Q2, and Q3 respectively; Pressure setting: Adjust V1 to make P1 display the target pressure value (e.g., 0.8 MPa); Independently adjust V2 and V3 to other pressure values ​​(such as 1.5MPa, 3.0MPa); Pressure holding test: Close the three branch regulating valves 5 and record the changes in the pressure gauge readings of each branch; Depressurization procedure: Single-path pressure relief: Open the branch pressure relief valve 10 on the first branch to release the pressure in only the first branch; Overall pressure relief: Open the main pipeline pressure relief valve 8.
