Description

Technical fields:

[0001] This utility model relates to the technical field of exhaust and liquid discharge valves, and more specifically to an energy storage exhaust and liquid discharge valve. Background technology:

[0002] The venting and draining valve is a key component in energy storage systems, used to discharge harmful gases and liquids in cases of battery thermal runaway, preventing explosions and other hazards, and playing a crucial role in ensuring the safe operation of energy storage systems. Current energy storage venting and draining valves consist of a valve seat, a valve core, and a sealing valve block. The valve seat has a valve orifice, while the sealing valve block is installed on the valve core. Under pressure, the valve core can overcome the spring force and move, which in turn moves the sealing valve block, opening the valve orifice within the valve seat and allowing gas and liquid to be discharged. However, if the gas or liquid contains micro-impurities, such as those near the valve orifice, it can affect the sealing of the sealing valve block. Therefore, the internal structure of the energy storage venting and draining valve needs to be optimized and improved to be unaffected by micro-impurities in the gas or liquid. Utility Model Content:

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing an energy storage exhaust and liquid discharge valve. The energy storage exhaust and liquid discharge valve has a modified internal structure, and micro-impurities in the gas or liquid will not affect the sealing performance of the energy storage exhaust and liquid discharge valve.

A first sealing ring is inserted into the first sealing ring groove, and a cylindrical annular valve core is inserted into the first sealing ring. A plurality of pressure relief grooves are formed on the outer wall of the middle part of the valve core. An annular discharge groove is formed on the inner wall of the valve seat at the end away from the release sleeve. A spring is inserted into the discharge groove, and the diameter of the inner wall of the discharge groove is larger than the diameter of the outer wall of the valve core.

[0005] The valve core has a conical end cap formed at one end away from the release sleeve. One end of the spring is fitted onto the middle of the end cap and abuts against the end cap, while the other end abuts against the valve seat.

[0007] Preferably, the spring inside the valve seat is spiral-shaped, and the end of the spring that contacts the valve seat abuts against a circular retaining ring formed on the inner wall of the discharge groove.

[0008] Preferably, a hexagonal limiting protrusion is formed on the outer wall of the middle part of the valve seat, an external thread is formed on the outer wall of the valve seat outside the discharge groove, a third sealing ring groove is formed on the outer wall of the valve seat between the external thread and the limiting protrusion, and a sealing ring is inserted in the third sealing ring groove.

[0009] Preferably, a second sealing ring groove is formed on the inner wall of the valve seat near the clamping sleeve, and a second sealing ring is inserted into the second sealing ring groove.

[0010] Preferably, the outer wall of the valve core at the end away from the end cap is formed with an annular guide ring, which abuts against the inner wall of the valve seat.

[0011] Preferably, a cylindrical protective sleeve is formed in the middle of the valve core upper end cap. The inlet of the protective sleeve is located in the discharge groove of the valve seat and a cylindrical positioning post is inserted therein. A circular connecting seat is formed at the end of the positioning post.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The internal structure of this energy storage exhaust and liquid drain valve has been modified so that micro-impurities in the gas or liquid will not affect the sealing performance of the energy storage exhaust and liquid drain valve.

Detailed implementation method:

[0021] Example: See Figure 1 , 2 As shown, an energy storage exhaust and discharge valve includes a valve seat 1 in the shape of a pipe joint. A release sleeve 2 is inserted into one end of the valve seat 1. The release sleeve 2 is snapped into the valve seat 1 by a retaining ring 3. A conical retaining sleeve 4 is clamped between the valve seat 1 and the release ring 2. An annular first sealing ring groove 11 is formed on the inner wall of the middle part of the valve seat 1. A first sealing ring 5 is inserted into the first sealing ring groove 11. A cylindrical annular valve core 6 is inserted into the first sealing ring 5. A plurality of pressure relief slots 62 are formed on the outer wall of the middle part of the valve core 6. An annular discharge groove 12 is formed on the inner wall of the valve seat 1 at the end away from the release sleeve 2. A spring 7 is inserted into the discharge groove 12. The diameter of the inner wall of the discharge groove 12 is larger than the diameter of the outer wall of the valve core 6.

[0022] The valve core 6 has a conical end cap 61 formed at one end away from the release sleeve 2. One end of the spring 7 is sleeved on the middle of the end cap 61 and abuts against the end cap 61, while the other end abuts against the valve seat 1.

[0023] The inner ring of the clamping sleeve 4 is formed with several clamping teeth, and the end of the release sleeve 2 is formed with a conical guide ring 21. The guide ring 21 is inserted into the clamping sleeve 4. By pressing the release sleeve 2, the guide ring 21 can be pushed into the clamping teeth, thereby expanding the clamping teeth. Then the air tube can enter the clamping sleeve 4 from the release sleeve 2. When the release sleeve 2 is reset, the clamping sleeve 4 can clamp and fix the air tube.

[0024] The spring 7 inside the valve seat 1 is vortex-shaped, and the end of the spring 7 that contacts the valve seat 1 abuts against a circular retaining ring 13. The retaining ring 13 is formed on the inner wall of the discharge groove 12. This structure of valve body is simple and compact, and is suitable for use as an exhaust valve.

[0025] A hexagonal limiting protrusion 17 is formed on the outer wall of the middle part of the valve seat 1. An external thread 16 is formed on the outer wall of the valve seat 1 outside the discharge groove 12. A third sealing ring groove 15 is formed on the outer wall of the valve seat 1 between the external thread 16 and the limiting protrusion 17. A sealing sleeve 8 is inserted in the third sealing ring groove 15. The valve seat 1 of the exhaust and discharge valve is a pipe joint structure. It can be fixed to the corresponding equipment by screwing. The sealing sleeve 8 is used to ensure the sealing performance.

[0026] A second sealing ring groove 14 is formed on the inner wall of the valve seat 1 near the clamping sleeve 4. A second sealing ring 10 is inserted into the second sealing ring groove 14. The second sealing ring 10 is used to ensure the seal between the air pipe inserted into the valve seat 1 and the valve seat 1. The function of the first sealing ring 5 is to isolate and prevent air leakage.

[0027] The outer wall of the valve core 6 away from the end cap 61 is formed with an annular guide ring 63. The guide ring 63 abuts against the inner wall of the valve seat 1, and the guide ring 63 ensures that the valve core 6 and the valve seat 1 are concentric.

[0028] If a vortex-shaped spring 7 is used, the spring 7 is exposed to the liquid or air inside the exhaust / drain valve. In air, the spring 7 is less prone to corrosion, but as a drain valve, the spring 7 is located in the liquid, which accelerates its corrosion. Therefore, the following structure is designed to protect the spring 7 and constrain its contact with the liquid: A cylindrical protective sleeve 64 is formed in the middle of the end cap 61 of the valve core 6. The inlet of the protective sleeve 64 is located in the discharge groove 12 of the valve seat 1 and a cylindrical positioning pin 9 is inserted therein. A circular connecting seat 91 is formed at the end of the positioning pin 91. A horizontal shaft 20 is inserted into the connecting seat 91, and both ends of the horizontal shaft 20 are respectively inserted and fixed to the valve seat 1. Figure 3 As shown;

[0029] The spring 7 is inserted inside the protective sleeve 64, with one end of the spring 7 abutting against the end of the protective sleeve 64 and the other end abutting against the positioning post 9; a T-shaped connecting post 30 is inserted into the end of the protective sleeve 64, and the end of the connecting post 30 passes through the spring 7 and is inserted and fixed to the positioning post 9. The connecting post 30 can restrict the positioning post 9 from detaching from the protective sleeve 64, and at the same time balance the pressure inside the protective sleeve 64.

[0030] The diameter of the connecting seat 91 is smaller than the diameter of the inner wall of the discharge tank 12, so the connecting seat 91 will not restrict the flow of liquid.

[0031] Working principle: This structure is an energy storage venting and draining valve. The internal sealing block has been eliminated and the structure of the valve core 6 has been modified. A pressure relief groove 62 is opened on the side wall of the valve core 6. Figure 2As shown, when the gas or liquid pressure on the left side of the valve core 6 increases, the pressure will push the valve core 6 to the right, so that the pressure relief slot 62 on the valve core 6 moves to the discharge slot 12 of the valve seat 1. Thus, the gas or liquid can pass through the pressure relief slot 62 and the discharge slot 12 of the valve seat 1 and then be output. When the liquid and gas contain some impurities, they will not affect the sealing and isolation effect of the first sealing gasket 45.

[0032] When negative pressure occurs on the left side of valve core 6, although valve core 6 will shift to the left, the end cap 61 of valve core 6 will still be on the right side of the first sealing gasket 45, which will not cause backflow in the energy storage exhaust and liquid discharge valve, and can effectively isolate it from the outside world.

[0033] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
