[0034] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0035] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0036] This application proposes a performance testing device 100 for cooling spray beams.

[0037] It is understandable that, such as Figure 1 As shown, the cooling spray beam 200 includes a beam body 201 and a spot spray valve 202. The spot spray valve 202 is installed on the beam body 201 and is used to spray emulsion. In some implementations, the cooling spray beam 200 can be a segmented cooling spray beam 200. The segmented cooling spray beam 200 includes a beam body 201, a female part 203 of an aviation plug, and a plurality of spot spray valves 202. The plurality of spot spray valves 202 are installed on the beam body 201 at intervals. The female part 203 is connected to the pneumatic chamber 2021 of the plurality of spot spray valves 202.

[0038] like Figure 2 As shown, the injection valve 202 includes a housing 2024 and a base 2026. The housing 2024 is provided with a valve core 2025 and a valve sleeve 2027. The housing 2024 is connected to the base 2026. The base 2026 is provided with a nozzle 2029. The housing 2024 forms a pneumatic chamber 2021, a mixing chamber 2023 and an emulsion chamber 2022. The outer shell 240 is provided with a pneumatic chamber inlet 20211 that communicates with the pneumatic chamber 2021. Compressed gas is suitable for entering the pneumatic chamber 2021 along the pneumatic chamber inlet 20211 to push the valve core 2025 to squeeze the emulsion in the emulsion chamber 2022 and spray it out from the nozzle 2029.

[0039] like Figure 2As shown, the housing 2024 is also provided with a mixing chamber 2023, and a spring 2028 is provided in the mixing chamber 2023. The spring 2028 is elastically connected between the valve sleeve 2027 and the valve core 2025 so as to realize the automatic reset of the valve core 2025 when the valve core 2025 is not subjected to external force. The housing 2024 is provided with an exhaust pipe 20231 that communicates with the mixing chamber 2023. The exhaust pipe 20231 is connected to the external atmospheric pressure so that the mixing chamber 2023 can enter and exit air through the exhaust pipe 20231 to adapt to the volume change of the mixing chamber 2023.

[0040] like Figure 1 As shown, the performance testing device 100 for cooling the spray beam includes: an air compressor 1, a first pipeline 2, and a second pipeline 3.

[0041] The air compressor 1 is provided with an air outlet 11. One end of the first pipeline 2 is connected to the air outlet 11, and the other end is used to connect to the female part 203 of the aviation plug of the cooling spray beam 200. The female part 203 is connected to the pneumatic chamber 2021 of the spot spray valve 202 of the cooling spray beam 200. One end of the second pipeline 3 is connected to the air outlet 11, and the other end is used to connect to the emulsion chamber 2022 of the spot spray valve 202. The first pipeline 2 is provided with a shut-off valve 23.

[0042] In this way, the supply and demand of compressed air in the first pipeline 2 can be controlled by the shut-off valve 23. For example, when testing the emulsion chamber 2022, the first pipeline 2 can be closed by the shut-off valve 23. At this time, compressed air enters the emulsion chamber 2022 only through the second pipeline 3 to detect the airtightness of the emulsion chamber 2022.

[0043] Alternatively, when simultaneously testing the pneumatic chamber 2021 and the emulsion chamber 2022, the first pipeline 2 can be opened by controlling the shut-off valve 23. At this time, one path of compressed air can enter the pneumatic chamber 2021 of the spray valve 202 through the first pipeline 2 and the female head part 203, and the other path of compressed air can enter the emulsion chamber 2022 of the spray valve 202 through the second pipeline 3. In this way, the airtightness of the pneumatic chamber 2021 and the emulsion chamber 2022 can be tested simultaneously.

[0044] Among them, the two compressed air channels can be set with specified parameters such as pressure and flow rate to simulate the sealing performance of the cooling spray beam 200 and the sensitivity of the spot spray valve 202 under rolling conditions.

[0045] For example, when the shut-off valve 23 controls the opening of the first pipeline 2, the pressure of the compressed air in the first pipeline 2 can be set to 0.5MPa and the pressure of the compressed air in the second pipeline 3 can be set to 0.8MPa to simulate the rolling environment. At this time, the airtightness of the female head part 203, the pneumatic cavity 2021 and the emulsion cavity 2022 can be detected.

[0046] In this way, the comprehensive performance of the cooling spray beam 200 can be tested using two compressed air streams. Its structure is simpler, reducing testing difficulty. Furthermore, the compressed air leaves no water or oil stains after testing, preventing problems such as corrosion inside the spray valve 202 or jamming of the valve core 2025, thus ensuring the product quality of the cooling spray beam 200.

[0047] According to the performance testing device 100 for cooling spray beam provided in the embodiments of this application, one compressed air can enter the pneumatic chamber 2021 of the spray valve 202 through the first pipe 2 and the female head part 203, and the other compressed air can enter the emulsion chamber 2022 of the spray valve 202 through the second pipe 3. In this way, the comprehensive performance of the cooling spray beam 200 can be tested through two compressed airs. Its structure is simpler and it is easier to reduce the testing difficulty. Moreover, the compressed air will not leave water stains or oil stains after the test, and will not cause problems such as rust inside the spray valve 202 or valve core 2025 jamming after the test, thereby ensuring the product quality of the cooling spray beam 200.

[0048] In some embodiments, such as Figure 3 As shown, the performance testing device 100 for cooling spray beams also includes: a male part 4 of an aviation plug, which is connected to the first pipeline 2 and is used to connect to the female part 203. The cooling spray beam 200 is provided with multiple point spray valves 202, and the pneumatic chamber 2021 of each point spray valve 202 is connected to the female part 203.

[0049] Therefore, the first pipeline 2 can be better connected to the female part 203 through the male part 4, and better connected to the pneumatic chamber 2021 of the multiple injection valves 202 through the female part 203, thereby realizing the detection of the airtightness of the pneumatic chamber 2021 of the multiple injection valves 202.

[0050] In some embodiments, such as Figure 3 As shown, the first pipeline 2 includes a first main pipeline 21 and a plurality of first sub-pipelines 22. The plurality of first sub-pipelines 22 are arranged in parallel and are all connected to the first main pipeline 21. Each first sub-pipeline 22 is used to connect to the pneumatic cavity 2021 of a point spray valve 202.

[0051] Therefore, compressed air can be supplied to the pneumatic chambers 2021 of multiple injection valves 202 through multiple first sub-pipes 22 respectively. In this way, if one of the first sub-pipes 22 is blocked, the normal passage of other first sub-pipes 22 will not be affected. Moreover, the multiple first sub-pipes 22 are set in parallel to improve detection efficiency.

[0052] In some embodiments, such as Figure 3 As shown, the shut-off valve 23 is located in the first sub-pipeline 22.

[0053] Therefore, the on / off state of the corresponding first sub-pipeline 22 can be controlled by the shut-off valve 23, so as to detect the airtightness of the pneumatic chamber 2021 of the injection valve 202 connected to the first sub-pipeline 22.

[0054] In some embodiments, such as Figure 3 As shown, a pressure relief valve 24 is provided on the first sub-pipeline 22.

[0055] Therefore, the residual compressed air in the first sub-pipeline 22 can be discharged by setting the pressure relief valve 24, thereby reducing the gas pressure in the first sub-pipeline 22.

[0056] like Figure 4 As shown, the pressure relief valve 24 includes a housing 240 and a pressure relief valve core 244. The housing 240 is provided with an inlet 241, an outlet 242, and a pressure relief port 243. When the pressure relief valve 24 is open, as... Figure 5 As shown, compressed air enters the pressure relief valve 24 through inlet 241 and then exits through outlet 242. When the pressure relief valve 24 is closed, as... Figure 6 As shown, the compressed air at outlet 242 will squeeze the pressure relief valve core 244 to close inlet 241. At the same time, the compressed air will be discharged from the pressure relief port 243 to discharge the residual compressed air in the first sub-pipeline 22.

[0057] In some embodiments, such as Figure 3 As shown, the first main pipeline 21 is connected to the first pressure reducing valve 25 and the first speed regulating valve.

[0058] Therefore, it is convenient to reduce the pressure of the compressed air in the first main pipeline 21 through the first pressure reducing valve 25, and it is convenient to reduce the speed of the compressed air in the first main pipeline 21 through the first speed regulating valve, so as to avoid the compressed air entering the first sub-pipeline 22 having too high pressure or too fast speed.

[0059] In some embodiments, such as Figure 3 As shown, the second pipeline 3 includes a second main pipeline 31 and multiple second sub-pipelines 32. The multiple second sub-pipelines 32 are arranged in parallel and are all connected to the second main pipeline 31. Each second sub-pipeline 32 is used to connect to the emulsion chamber 2022 of a point spray valve 202.

[0060] Therefore, compressed air can be supplied to the emulsion chambers 2022 of multiple injection valves 202 through multiple second sub-pipes 32 respectively. In this way, if one of the second sub-pipes 32 is blocked, the normal passage of other second sub-pipes 32 will not be affected. Moreover, the multiple second sub-pipes 32 are set in parallel to improve the detection efficiency.

[0061] In some embodiments, such as Figure 3 As shown, a second pressure reducing valve 33 is connected to the second main pipeline 31.

[0062] This allows the compressed air in the second main pipeline 31 to be depressurized via the second pressure reducing valve 33, so as to avoid excessive pressure of the compressed air entering the second sub-pipeline 32.

[0063] In some embodiments, such as Figure 3 As shown, a second speed control valve is connected to the second main pipeline 31.

[0064] This allows the speed of compressed air in the second main pipeline 31 to be reduced by the second speed control valve 34, so as to avoid the compressed air entering the second sub-pipeline 32 being too fast.

[0065] In some embodiments, such as Figure 3 As shown, a pressure gauge 5 is installed at the air outlet 11.

[0066] Therefore, the pressure of the compressed air at the outlet 11 can be detected by the pressure gauge 5, so as to realize the control of the compressed air pressure.
