[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Next, the concepts involved in the present application will be described first in conjunction with the accompanying drawings. It should be noted here that the following descriptions of each concept are only for making the content of the present application easier to understand, and do not represent a limitation on the protection scope of the present application; at the same time, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0033] Embodiment: As Figures 1 to 8 shown, the present invention provides a test tool for a vacuum valve, including a detection gas path device. The detection gas path device includes an air supply unit. The air supply unit is connected with a plurality of detection gas path devices 1 through pipelines. The detection gas path device 1 includes an air supply mechanism 2, a positioning mechanism 3 and a vacuum mechanism 4. One end of the positioning mechanism 3 is fixedly connected to the air supply mechanism 2, and the other end is fixedly connected to the vacuum mechanism 4. The air supply mechanism 2, the positioning mechanism 3 and the vacuum mechanism 4 are all interconnected through pipelines;

[0034] The positioning mechanism 3 includes a base. A first right-angle seat 31 is fixedly installed on the top of the base. The bottom of the first right-angle seat 31 is rotatably connected to a second right-angle seat 32. A first motor 33 for driving the second right-angle seat 32 to rotate is fixedly installed at the bottom of the base. First lifting platforms 34 are fixedly connected to both the first right-angle seat 31 and the second right-angle seat 32. An adjusting component 5 is fixedly connected to the first lifting platform 34. An auxiliary blanking component 6 is fixedly installed on the side wall of the adjusting component 5. A power supply component 7 is fixedly installed on the second right-angle seat 32. Air pipes 35 are fixedly installed on the side walls of both the first right-angle seat 31 and the second right-angle seat 32. Docking components 8 are slidably installed in the air pipes 35. The two docking components 8 cooperate with each other to connect the valve to be tested with the air pipes 35 at both ends.

[0035] As a specific embodiment provided by a test fixture for a vacuum valve, the air supply unit includes an air compressor 10. A CDA main pipeline 11 is externally connected to the air compressor 10. A first filter 12 is fixedly connected to one end of the CDA main pipeline 11 away from the air compressor 10.

[0036] As a further illustration of the embodiments of the present invention, in addition to conventional long-tube vacuum valves, vacuum valves on the market also have vacuum valves of various angles, such as right-angle vacuum valves, acute-angle vacuum valves, and obtuse-angle vacuum valves. However, the vacuum valve testing tooling in the prior art has certain singleness and limitations and cannot be applied to the testing of vacuum valves of various angles. In this embodiment, the complete testing process of the conventional long-tube vacuum valve is as follows: dry compressed air or nitrogen is injected into the CDA main pipeline 11 through the air compressor 10. The injected compressed air passes through the first filter 12 and then flows into multiple detection gas circuit devices 1 through the pipeline. In each detection gas circuit device 1, the compressed air passes through the pressure regulating valve 21, the diaphragm valve 22, the needle valve 23, and the second filter 24 in sequence before entering the vacuum gauge 25 (in this embodiment, a heating device is provided at the pipeline connection of the vacuum gauge 25, which is used to heat the compressed gas in the pipeline to facilitate the testing of the valve under extreme working conditions). After ensuring that the gas in all gas supply mechanisms 2 is circulated, , transport the valve to be tested to the positioning mechanism 3, adjust the valve to be tested to be coaxial with the air pipe 35 through the cooperation of the adjustment component 5 and the first lifting platform 34, adjust the power supply component 7, connect the power supply component 7 to the power interface of the electric device on the valve to be tested, and after the valve to be tested is connected to the power supply component 7 and powered on, start the docking component 8 on the first right-angle seat 31 and the second right-angle seat 32, connect the two air pipes 35 with the two ends of the valve to be tested, fill one end of the valve to be tested with gas through the gas supply mechanism 2, and then remove the air in the other end of the valve to be tested through the vacuum mechanism 4, test the pressure difference at both ends of the valve to be tested, and test the airtightness of the valve to be tested. After a series of valve tests, reset the docking components 8 at both ends of the valve to be tested, push the valve to be tested out of the adjustment component 5 through the auxiliary unloading component 6, and lay a conveyor belt on one side of each detection gas path device 1 to receive the valve to be tested that is pushed away, thereby forming a complete and continuous valve testing operation process. As a further preferred scheme of this embodiment, when facing vacuum valve tests at various other angles, in this embodiment, the first motor 33 drives the second right-angle seat 32 to rotate a preset angle so that the second right-angle seat 32 and the first right-angle seat 31 form an angle that is the same as the angle of the valve to be tested, and the valve to be tested is placed in the adjusting component 5. After adjustment and further restriction by the adjusting component 5, the valve to be tested is fixed in the adjusting component 5, and the above steps are repeated to drive the docking component 8 and the power supply component 7 to connect the air supply mechanism 2 and the vacuum mechanism 4 with the valve to be tested. After performing the above tests, the restrictions of the adjusting component 5 and the docking component 8 on the component to be tested are released, and the valve to be tested is pushed away by the auxiliary unloading component 6 to complete the test of the unconventional vacuum valve, so that the present device can test the transfer vacuum valves with various angles, thereby improving the scope of application of the present device.

[0037] As a specific embodiment provided by a test tool for a vacuum valve, the adjusting assembly 5 includes a bidirectional telescopic box 51 fixedly installed on the top of the first lifting table 34. One end of the bidirectional telescopic box 51 is fixedly connected with a first baffle 52, and the output end of the other bidirectional telescopic box 51 is rotatably installed with a second baffle 53 connected to the auxiliary blanking assembly 6. When blanking the valve body to be tested, the second baffle 53 can be rotated to incline downward through the auxiliary blanking assembly 6.

[0038] As a further description of the embodiment of the present invention, in the bidirectional telescopic box 51 in this embodiment, there are two output ends (the bidirectional telescopic box 51 in this embodiment is a combination of existing telescopic devices, such as a bidirectional screw or two unidirectional screws respectively driving two clamping plates to move mirror-symmetrically), and the telescopic paths of the two output ends are exactly the same. By adjusting the distance between the first baffle 52 and the second baffle 53, the first baffle 52 and the second baffle 53 are both pressed against the side wall of the valve to be tested, and the valve to be tested is clamped and fixed between the first baffle 52 and the second baffle 53. Because the central bisector of the bidirectional telescopic box 51 and the air pipe 35 is the same, when the valve to be tested is clamped and fixed, the valve to be tested is at the central position of the bidirectional telescopic box 51. Then, through the first lifting table 34, the clamped valve to be tested is lifted to be coaxially arranged with the air pipe 35, ensuring that the end of the air pipe 35 must be aligned with the end of the valve to be tested, and avoiding the leakage of the test gas when the air pipe 35 and the valve to be tested are misaligned.

[0039] As a specific embodiment provided by a test tool for a vacuum valve, the auxiliary blanking assembly 6 includes a first cylinder 61 fixedly installed on the side wall of the first baffle 52. The output end of the first cylinder 61 penetrates through the first baffle 52 and is fixedly connected with a push plate 62. One side wall of the output end of the bidirectional telescopic box 51 is fixedly connected with a second motor 63, and the output end of the second motor 63 is fixedly connected with the second baffle 53.

[0040] As a further description of the embodiment of the present invention, in this embodiment, after the valve to be tested is completed with the test, the second motor 63 drives the second baffle 53 to rotate a preset angle, so that the second baffle 53 no longer presses against the outer wall of the valve to be tested. At this time, the second baffle 53 inclines downward to form a slope. Then, the first cylinder 61 is started, and the push plate 62 is driven by the first cylinder 61 to push the valve to be tested towards the second baffle 53 until the valve to be tested slides off the adjusting assembly 5 along the inclined surface formed by the second baffle 53, so as to achieve the function of auxiliary blanking.

[0041] As a specific embodiment provided by a test fixture for a vacuum valve, the docking assembly 8 includes a sliding tube 81 sleeved in the air tube 35. A plurality of protrusions 811 are fixedly connected to the outer wall of the sliding tube 81 along the circumferential direction of the sliding tube 81. The plurality of protrusions 811 are commonly connected to the same limiting ring 82. A plurality of sliding grooves 351 for the protrusions 811 to slide are formed on the side wall of the air tube 35. A second cylinder 83 is fixedly installed on the top of the air tube 35, and the output end of the second cylinder 83 is fixedly connected to the limiting ring 82. A sealing gasket 84 is fixedly installed inside the end of the sliding tube 81.

[0042] As a further description of the embodiment of the present invention, in this embodiment, the plurality of protrusions 811 have a limiting effect, so that the sliding tube 81 can only reciprocate axially along the air tube 35. The sealing gasket 84 is installed in the sliding tube 81. When the second cylinder 83 drives the sliding tube 81 to slide, the end with the sealing gasket 84 is attached to the end of the valve to be tested, so that the sealing gasket 84 serves as a sealing means between the air tube 35 and the valve to be tested. The sealing gasket 84 in this embodiment is made of rubber with a certain thickness and deforms after being resisted by the sealing rings at both ends of the component to be tested, thereby improving the sealing effect.

[0043] As a specific embodiment provided by a test fixture for a vacuum valve, the power supply assembly 7 includes a second lifting platform 71 installed on the second right-angle seat 32. A telescopic box 72 is fixedly installed on the top of the second lifting platform 71. An electric plug board 73 is fixedly installed on the output end of the telescopic box 72. A plurality of sockets 731 are arranged on the electric plug board 73 from top to bottom.

[0044] As a further description of the embodiment of the present invention, in this embodiment, the power supply connector of the valve to be tested is fixed on the side wall of the valve to be tested. After the valve to be tested is clamped and fixed by the adjusting assembly 5, the telescopic box 72 is started (the telescopic box 72 in this embodiment is a conventional existing telescopic device, such as a screw, a cylinder or an oil cylinder, etc.), and the electric plug board 73 with the sockets 731 is moved closer to the side wall of the valve to be tested until the power supply connector of the valve to be tested extends into the socket 731, so that the electric device in the valve to be tested is powered on. By sending a control signal to the electric device, the electric device issues an instruction to open or close the valve, so as to cooperate with different valve tests. As a further description of this embodiment, before the valve to be tested is tested, the second lifting platform 71 is adjusted adaptively along the direction parallel to the ground of the second right-angle seat 32 according to the models of different valves to be tested, so as to ensure that the socket 731 and the power supply connector of the valve to be tested can be successfully docked.

[0045] As a specific embodiment provided by a test fixture for a vacuum valve, anti-collision pads 9 are fixedly installed on the tops of the first lifting platform 34 and the second lifting platform 71.

[0046] As a further illustration of the embodiments of the present invention, in this embodiment, when the valve to be tested is placed in the adjustment assembly 5, the first baffle 52 and the second baffle 53 in the adjustment assembly 5 do not contact the side wall of the valve to be tested. Therefore, an anti-collision pad 9 is laid to prevent damage caused by bumping when the valve to be tested enters the adjustment assembly 5.

[0047] As a specific embodiment provided by a test tool for a vacuum valve, the air supply mechanism 2 includes a pressure regulating valve 21 connected to the first filter 12 through a pipeline. The pressure regulating valve 21 is sequentially connected with a diaphragm valve 22, a needle valve 23, a second filter 24, and a vacuum gauge 25 through pipelines, and the vacuum gauge 25 is communicated with the air pipe 35 through a pipeline.

[0048] As a specific embodiment provided by a test tool for a vacuum valve, the vacuum mechanism 4 includes bellows 41 communicated with the air pipe 35, and a plurality of bellows 41 are commonly connected to the same dry pump 42.

[0049] As a further illustration of the embodiments of the present invention, in this embodiment, after the valve to be tested is connected to the air pipe 35, compressed air is injected into one end of the valve to be tested through the vacuum gauge 25. At the other end of the valve to be tested, the air inside the valve to be tested is evacuated by the dry pump 42 to test the pressure difference at both ends of the valve to be tested to determine whether there is air leakage. In the entire detection air path device 1, there is an electronic control module that is connected and used to control all electronic control devices. Each detection air path device 1 supports collecting the on-off signals of the valve to be tested, and calculates the on-off time of the valve to be tested through data analysis. Sensors are provided on each pressure regulating valve 21, diaphragm valve 22, and needle valve 23, and the sensors of the pressure regulating valve 21, diaphragm valve 22, and needle valve 23 are all passive dry contact type sensors. The driving times of each valve in each detection air path device 1 are recorded through the electronic control module, and the opening and closing times, leakage rates, and particles of each valve are regularly recorded. The various parameters of the valve to be tested are analyzed through the recorded data. Each detection air path device 1 is set with a target pressure value. When the pressure of the detection air path device 1 exceeds the set target pressure value, the diaphragm valve 22 is driven to close to stop the inflow of the flow rate. When the pressure drops below 90% of the target pressure value again, the diaphragm valve 22 is driven to open again. That is, the vacuum gauge 25 converts the internal pressure into an electrical signal and sends it to the electronic control module. When the gas inside the vacuum gauge 25 reaches the set value, the diaphragm valve 22 is controlled by the electronic control module to close to stop the inflow of the flow rate. At the same time, a three-color lamp is set in the electronic control module to stop the air supply and be used for warning when the detection air path device 1 reaches the target pressure value.
