[0002] Mobile pressure vessels, such as liquid tank trucks, require detachable special loading and unloading hoses during filling operations. These hoses connect the liquid tank truck to the storage tank or pump at the filling location for filling.

[0003] To ensure the safety of equipment and personnel, pressure tests must be conducted on dedicated loading and unloading hoses regularly. The specific requirements are: regular inspections should primarily use hydraulic tests, with pneumatic tests used when there are special needs. The test pressure for the pressure test should be 1.5 times the nominal pressure of the dedicated loading and unloading hose.

[0004] When conducting pressure tests, companies can choose to use third-party service providers or conduct them themselves. For companies that use a small number of special loading and unloading hoses and have a complicated procurement process (including physical products and services), choosing a third-party service provider is costly in terms of effort, time, and money, and is not economical. Therefore, these companies urgently need devices or equipment suitable for conducting pressure tests on special loading and unloading hoses so that they can conduct pressure tests themselves.

[0037] Reference Appendix Figure 1-5This embodiment provides a hose pressure testing device for performing pressure tests on hoses. Its structure includes: a placement platform 1, hose fixing seats 2, ram-horn connectors 3, an external pressure gauge 4, a pressure testing device 5, and a first threaded connector 6. The placement platform 1 has two sets of opposing hose fixing seats 2, with ram-horn connectors 3 on their opposing surfaces and first threaded connectors 6 on their non-opposing surfaces. The inner cavities of the ram-horn connectors 3 and the first threaded connectors 6 are connected. The placement platform 1 has rope holes 1-6 for threading ropes to secure the hose. The two sets of first threaded connectors 6 are respectively connected to the external pressure gauge 4 and the pressure testing device 5, which has a built-in pressure gauge.

[0038] When performing a pressure test (pressure test) on the hose using the above-mentioned device, since the hose has flanges (or ram's horn joints) at both ends, it can be placed between two hose fixing seats 2. Align the flanges (or ram's horn joints) with the ram's horn joints 3 on the hose fixing seats 2 and connect and tighten them. Then, tie a rope to the outside of the hose, pass the rope through the rope holes 1-6 on the placement platform 1 and connect and tighten it to prevent the hose from swinging and injuring people during the pressure test. Then, according to the pressure test requirements, use the external pressure gauge 4 and the pressure testing equipment 5 to operate step by step to complete the pressure test of the hose.

[0039] Since the hose has a certain length, an external pressure gauge 4 and a pressure testing device 5 with a built-in pressure gauge are respectively installed at both ends of the hose. During pressure testing, the reading of the external pressure gauge 4 is used as the reference. This can avoid the end of the hose closest to the external pressure gauge 4 from not reaching the required test pressure due to pressure loss, thereby ensuring the reliability of the pressure resistance test results.

[0040] Both the external pressure gauge 4 and the pressure testing equipment 5 with a built-in pressure gauge are conventional products in this field. Their structure and model can be selected according to actual needs, and no specific limitations are made here.

[0041] In this embodiment, the bottom of the placement platform 1 is provided with detachable support legs 8. The support legs 8 include a first connecting plate 8-1, a support column 8-2, and a second connecting plate 8-3 that are fixedly connected in sequence. The first connecting plate 8-1 is provided with a first connecting hole 11 for installing bolts to connect the placement platform 1; the second connecting plate 8-3 is provided with a second connecting hole 12 for installing bolts to connect the placement area of ​​the device. The device is fixedly connected to the ground of the placement area by the bolts installed in the second connecting hole 12, and the support legs 8 are fixedly connected to the placement platform 1 by the bolts installed in the first connecting hole 11. This can prevent the impact of hose pressure vibration or swaying on the placement platform 1 during the pressurization process, improve the stability of the placement platform 1, and prevent the placement platform 1 from moving and affecting the efficiency of personnel testing operations and the safety of equipment and personnel.

[0042] To accommodate hoses of different lengths, in this embodiment, the placement platform 1 is configured as a detachably connected first platform 1-1 and second platform 1-2. Two sets of hose fixing seats 2 are respectively set on the first platform 1-1 and the second platform 1-2. The lengths of the first platform 1-1 and the second platform 1-2 can be configured according to different needs. The connecting parts of the first platform 1-1 and the second platform 1-2 are the first step 1-3 and the second step 1-4 respectively. The bottom surface of the first step 1-3 and the top surface of the second step 1-4 abut against each other. The two are respectively provided with corresponding third connecting holes 13, and bolts for connecting the two are passed through the third connecting holes 13. The top surfaces of the first step 1-3, the first platform 1-1 and the second platform 1-2 are flush to ensure that the top surface of the entire placement platform 1 is continuous and smooth, so that the hose can be stably placed on it.

[0043] To ensure the safety of test personnel, in this embodiment, a first side plate 9 and a second side plate 10 are respectively provided on the same side of the first platform 1-1 and the second platform 1-2. The two ends of the first side plate 9 extend to the side edge of the first platform 1-1 and the side edge of the first step 1-3, respectively. The two ends of the second side plate 10 extend to the opposite side edge of the second platform 1-2, respectively. The first side plate 9 and the second side plate 10 are used to protect the hose from swinging and injuring people after the hose is pressurized.

[0044] To facilitate the assembly, use, and maintenance of the device, in this embodiment, a connecting hole 2-1 is provided on the hose fixing seat 2. One side of the connecting hole 2-1 is connected to the first threaded connector 6, and the other side is connected to the second threaded connector 7. The outer walls of the first threaded connector 6 and the second threaded connector 7 are respectively threaded. The second threaded connector 7 is threadedly connected to the ram's horn connector 3. The two sets of first threaded connectors 6 are used to connect the external pressure gauge 4 and the pressure testing equipment 5, respectively. Since the connector models at both ends of different hoses may be different, the ram's horn connector 3 in this embodiment is assembled in the above-mentioned detachable manner, so that different ram's horn connectors 3 can be replaced at any time to adapt to different hoses.

[0045] Specifically, the ram's horn connector 3 includes an internal threaded sleeve 3-1 and a wing plate 3-2. The wing plate 3-2 and the hose fixing seat 2 are located on both sides of the internal threaded sleeve 3-1. The wing plate 3-2 extends radially from the outer wall of the internal threaded sleeve 3-1 and has a fourth connecting hole 14 for installing bolts for connecting the flanges (or ram's horn connectors) at both ends of the hose.

[0046] The shape of the aforementioned hose fixing seat 2 can be configured according to actual needs. In this embodiment, the hose fixing seat 2 is configured as a plate with several vertical grooves 2-2. The vertical grooves 2-2 make the cross-sectional profile of the hose fixing seat 2 concave and convex. The placement platform 1 is provided with slots 1-5 that match the cross-sectional profile of the hose fixing seat 2. The hose fixing seat 2 and the placement platform 1 are connected by a socket joint, which makes installation and removal easier. Since the placement platform 1 itself has a certain thickness, the slots 1-5 can also be configured with an appropriate depth according to needs. Actual tests have shown that the stability of the socket joint connection can meet the test requirements. If it is necessary to further enhance the connection stability between the hose fixing seat 2 and the placement platform 1 in special circumstances, bolts can be inserted through the bottom surface of the placement platform 1, with the top of the bolts inserted through the bottom surface of the hose fixing seat 2. Alternatively, ropes for binding and fixing the hose fixing seat 2 can be inserted through the rope holes 1-6.

[0047] Compared with the prior art, the advantages of this utility model are as follows: it provides a simple assembly hose pressure testing device, which can fix the hose and carry out pressure testing, improving the convenience and economy of enterprises to conduct pressure resistance tests on hoses themselves; it uses an external pressure gauge 4 to ensure the reliability of test results and avoid test errors caused by pressure loss due to excessive hose length.
