Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a valve testing device for a lead-acid valve-controlled battery. Background Art

[0002] Batteries are widely used as backup energy sources in various communications and information processing applications. In the event of an external power outage, batteries are needed to power equipment. Battery failure can cause significant losses or even disaster in the communications and information industries, making battery safety paramount. To ensure battery performance, regular testing is essential. While testing battery performance, such as capacity, voltage, and internal resistance, often focuses on the quality of valves in lead-acid valve-regulated batteries.

[0003] The quality of the valve of a lead-acid valve-regulated battery is related to the reliable use and safety of the lead-acid valve-regulated battery. If the valve of a lead-acid valve-regulated battery fails, it may cause gas leakage during the chemical reaction of the battery. It may also cause the gas to be unable to be discharged when the internal gas pressure of the battery is too high, causing a series of problems such as battery expansion, which will eventually lead to battery failure or a safety accident.

[0004] Patent document CN205580711U discloses a valve testing device for lead-acid valve-regulated batteries. After turning on the power switch, the valve of the lead-acid valve-regulated battery to be tested is fixed to the air outlet of the test bench. The control circuit board activates the air pressure pump, continuously generating compressed gas. The pressure on the valve increases continuously. When the designed opening pressure of the exhaust port is reached, the valve should open. If the designed opening pressure is not reached, the valve is open and the valve is considered to be faulty. Similarly, if the valve does not open when the designed opening pressure is exceeded, the valve is also considered to be faulty. This device can simply, quickly, and accurately test the valve quality of lead-acid valve-regulated batteries. However, this test device can only test one battery valve at a time, resulting in low testing efficiency. Utility Model Content

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] Example 1: Reference Figure 1-Figure 5 As shown, a valve testing device for a lead-acid valve-regulated battery includes a housing 1 with an inner tank 8 defined therein. A gas pipe 2 connected to the inner tank 8 is fixed to the housing 1 and mounted on the gas pipe 2. A solenoid valve 3 is mounted on the gas pipe 2. A plurality of blind holes 15 are defined at the upper end of the housing 1. The blind holes 15 communicate with the inner tank 8 via a lower passage 9 within the housing 1.

[0044] The housing 1 is provided with a cover plate 4 at the upper end. An upper tube 6 corresponding to the blind hole 15 is fixed to the upper end of the cover plate 4. An elastic membrane 13 is fixed inside the upper tube 6. A trigger assembly is installed inside the upper tube 6 above the elastic membrane 13. When the elastic membrane 13 is deformed upward, the trigger assembly is activated. The elastic membrane 13 is an elastic rubber membrane.

[0045] A transparent plate 7 is fixed inside the upper end of the upper tube 6 , and an indicator light 10 is fixed at the lower end of the transparent plate 7 .

[0046] A plug sleeve 17 concentric with the upper tube 6 is fixed to the lower end of the cover plate 4, and the plug sleeve 17 is communicated with the upper tube 6. Specifically, the upper tube 6 is communicated with the plug sleeve 17 below it through the upper channel 14 on the cover plate 4.

[0047] The plug sleeve 17 is slidably and sealedly inserted into the blind hole 15. A battery valve 16 is placed in the plug sleeve 17. The lower end of the battery valve 16 is tightly against the bottom of the blind hole 15. The lower end of the battery valve 16 is connected to the lower channel 9, and the upper end of the battery valve 16 is in sealing contact with the lower end of the cover plate 4.

[0048] A groove is provided at the upper end of the shell 1, in which a push switch 20 is fixed. When the lower end of the cover 4 contacts the upper end of the shell 1, the push switch 20 is turned on, and the push switch 20, the solenoid valve 3, the trigger assembly, the indicator light 10 and the power supply are electrically connected.

[0049] The lower end of the cover plate 4 in the socket 17 is fixedly and sealedly connected with a rubber ring 19 , the upper channel 14 is communicated with the inner hole of the rubber ring 19 , and the upper end of the battery valve 16 is in sealing contact with the cover plate 4 through the rubber ring 19 .

[0050] An annular groove is formed on the side wall of the blind hole 15 , and a rubber sleeve 18 is fixedly and sealedly connected in the annular groove. After the inserting sleeve 17 is inserted into the blind hole 15 , it is in sealing contact with the rubber sleeve 18 .

[0051] The trigger assembly includes a lower elastic contact piece 12 fixed in the upper tube 6, the lower elastic contact piece 12 is located above the elastic membrane 13, and an upper elastic contact piece 11 is fixed in the upper tube 6 above the lower elastic contact piece 12. The upper elastic contact piece 11, the lower elastic contact piece 12, the indicator light 10 and the power supply are electrically connected.

[0052] When testing the battery valve 16, connect the air source to the air pipe 2. Place the battery valve 16 to be tested into the socket 17 in sequence, and then insert the socket 17 into the blind hole 15 of the housing 1 through the cover plate 4. Then press the cover plate 4 downward. After the cover plate 4 contacts the upper end of the housing 1, press the switch 20 to contact, the solenoid valve 3 opens, and compressed air enters the inner tank 8 and the lower channel 9, increasing the air pressure in the inner tank 8 and the lower channel 9. After the cover plate 4 contacts the upper end of the housing 1, the socket 17 and the rubber sleeve 18 are in sealed contact. The upper end of the battery valve 16 is in sealed contact with the cover plate 4 through the rubber ring 19, and the lower end of the battery valve 16 is tightly against the bottom of the blind hole 15.

[0053] If the battery valve 16 is unobstructed, compressed air enters the upper tube 6 below the elastic membrane 13 through the battery valve 16 and the upper channel 14. The elastic membrane 13 deforms upward, causing the lower elastic contact 12 to move upward and contact the upper elastic contact 11. After the lower elastic contact 12 moves upward and contacts the upper elastic contact 11, the indicator light 10 lights up. The lighting of the indicator light 10 indicates that the battery valve 16 below it is unobstructed. If the indicator light 10 is off, the battery valve 16 below it is blocked.

[0054] The test device can sequentially place multiple battery valves 16 to be tested in the insert sleeve 17, and can test multiple battery valves 16 at a time, thereby improving the test efficiency of the battery valves 16. During the test, the status of the battery valve 16 can be easily known by the status of the indicator light 10.

[0055] Example 2: Based on Example 1, refer to Figure 1 As shown, flanges 5 are fixed at both ends of the cover plate 4.

[0056] The flange 5 is provided to facilitate the tester to hold the cover plate 4 .

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
