Description

Technical Field

[0001] This utility model relates to the field of integrated valve testing technology, and in particular to an integrated valve cleanliness device. Background Technology

[0002] Integrated valves typically consist of components such as valve body, valve core, valve seat, spring, and electromagnet. They integrate multiple valves with different functions (such as directional control valves, pressure control valves, and flow control valves) into a compact valve body. The valves work together through internal flow channels and control mechanisms. This integrated design reduces piping connections and installation space, and improves the compactness and reliability of the system.

[0003] A search of Chinese patent publication number "CN218470578U" reveals a "particulate matter analyzer sampling pipeline cleanliness inspection device." This device utilizes a miniature camera with a built-in supplementary lighting mechanism to ensure the camera's applicability and image clarity. A camera control board and visual terminal allow for visualization of the video data captured by the miniature camera, facilitating the inspection of the sampling pipeline. Different conveying mechanisms enable the visual inspection of various sampling pipeline components.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. Due to the small size of the internal pipeline of the integrated valve, the inspection device relies on a miniature camera for visual inspection. However, the small diameter and complex structure of the internal pipeline of the integrated valve make it impossible for the camera to penetrate deeply or capture clear images, resulting in blind spots and making it difficult to perform inspections.

[0010] The dual-way two-position two-way valve has a replacement structure on its side wall;

[0011] The replacement structure includes an A intake port and a B intake port. The dual-way two-position two-way valve has an A outlet port and a B outlet port respectively on the side wall away from the A intake port. The A intake port and the A outlet port are connected, and the B intake port and the B outlet port are connected.

[0012] Preferably, the air inlet of the three-way valve is provided with a first air pipe, one of the air outlets of the three-way valve is connected to the air inlet A via a second air pipe, and the other air outlet of the three-way valve is connected to a third air pipe.

[0014] (III) Beneficial Effects

[0015] Firstly, by setting up a three-way valve, a dual-position two-way valve, a particle detector, and a filter, the cleanliness of the integrated valve can be tested using the principle of air transport carrying impurities inside the valve, which improves convenience. At the same time, after testing the contaminated integrated valve, the operator can disconnect the sixth air pipe from the particle detector and connect it to the filter inlet, connect the fifth air pipe to the particle detector inlet, and disconnect the second air pipe from the three-way valve and connect it to the fourth air pipe and the outlet of the three-way valve.

[0023] This application provides an integrated valve cleanliness device that effectively solves the technical problem that existing devices are inconvenient for inspecting the internal pipelines of integrated valves. By setting up a three-way valve, a dual-way two-position two-way valve, a particle detector, and a filter, the cleanliness can be detected using the principle of air transport to carry impurities inside the integrated valve, improving convenience. Furthermore, after inspecting the contaminated integrated valve, the operator can disconnect the sixth air pipe from the particle detector and connect it to the filter inlet, while simultaneously connecting the fifth air pipe to the particle detector inlet and disconnecting the second air pipe from the three-way valve, replacing it with a fourth air pipe connected to the outlet of the three-way valve. Then, the second and third air pipes can be connected to the corresponding interfaces of the new integrated valve to be tested, facilitating alternating use and improving efficiency. Additionally, by setting up the three-way valve and the dual-way two-position two-way valve, after the air pump is started, residual particles in the original contaminated air path are carried by the airflow into the filter for removal, thus providing auxiliary cleaning and improving convenience.

[0024] Example

[0025] like Figure 1 - Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that existing devices are not convenient for inspecting the internal pipelines of integrated valves. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides an integrated valve cleanliness device, including a three-way valve 11, a dual-way two-position two-way valve 12, a particle detector 13, and a filter 14;

[0027] A replacement structure is provided on the side wall of the dual-way two-position two-way valve 12;

[0028] The replacement structure includes an A intake port 15 and a B intake port 17. The side wall of the dual-way two-position two-way valve 12 away from the A intake port 15 is provided with an A outlet port 16 and a B outlet port 18 respectively. The A intake port 15 and the A outlet port 16 are connected, and the B intake port 17 and the B outlet port 18 are connected. The intake end of the three-way valve 11 is provided with a first air pipe 19, which is connected to an external air pump. One of the outlet ends of the three-way valve 11 is connected to the A intake port 15 by a second air pipe 21, and the outlet end of the other three-way valve 11 is connected to a third air pipe 22.

[0029] By setting up a three-way valve 11, a dual-position two-way valve 12, a particle detector 13, and a filter 14, the cleanliness of the integrated valve can be detected using the principle of air transport to carry impurities inside the valve, improving convenience. At the same time, after the contaminated integrated valve has been tested, the operator can disconnect the sixth air pipe 25 from the particle detector 13 and connect it to the inlet of the filter 14, connect the fifth air pipe 24 to the inlet of the particle detector 13, and disconnect the second air pipe 21 from the three-way valve 11 and connect it to the fourth air pipe 23 and the outlet of the three-way valve 11. Then, the second air pipe 21 and the third air pipe 22 can be connected to the corresponding interface of the new integrated valve to be tested, which is convenient for alternating use and improves efficiency.

[0030] By setting a three-way valve 11 and a two-way two-position valve 12, the residual particles in the original polluted air path are carried into the filter 14 for removal after the air pump is started, thus enabling auxiliary cleaning and improving convenience.

[0031] A fourth air pipe 23 is connected to the B air inlet 17; a fifth air pipe 24 is connected to the A air outlet 16 and the air inlet of the filter 14; and a sixth air pipe 25 is connected to the B air outlet 18 and the air inlet of the particle detector 13.

[0032] By setting up filter 14, the transmission of polluted pipeline gas can be filtered, thus improving environmental friendliness.

[0033] Working principle:

[0034] First, the staff connects the third air pipe 22 and the fourth air pipe 23 to a pair of connecting joints of the integrated valve. After starting the external air pump, the gas enters the three-way valve 11 through the first air pipe 19, and then flows into the particle detector 13 through the internal channel of the integrated valve, the fourth air pipe 23, the dual-way two-position two-way valve 12 and the sixth air pipe 25. If the particle detector 13 shows that there are no particles in the gas, the cleanliness of this set of joints is deemed to be qualified. Then the above testing process is repeated to test the remaining joints. If there are no abnormalities in the tests, it can be confirmed that the cleanliness of the integrated valve is up to standard.

[0035] In the second step, if the particle detector 13 detects particles in the gas and triggers an alarm, the sixth gas pipe 25 can be disconnected from the particle detector 13 and connected to the inlet of the filter 14. At the same time, the fifth gas pipe 24 can be connected to the inlet of the particle detector 13. Then, the second gas pipe 21 can be disconnected from the three-way valve 11 and connected to the fourth gas pipe 23 and the outlet of the three-way valve 11. Then, the second gas pipe 21 and the third gas pipe 22 can be connected to the corresponding interface of the new integrated valve to be tested. After starting the air pump, the residual particles in the original contaminated gas path (the area inside the fourth gas pipe 23 and the sixth gas pipe 25 and between the B inlet interface 17 and the B outlet interface 18) will enter the filter 14 with the airflow to be cleared, so as to avoid contaminating the new detection circuit. At the same time, the particle detector 13 monitors the cleanliness of the new circuit through the fifth gas pipe 24 to eliminate false judgments.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
