[0002] Refrigerant, also known as refrigerant, is a medium substance used to complete energy conversion in various heat engines. These substances usually increase power through reversible phase change, such as steam in steam engines, refrigerant in refrigerators, etc. When a general steam engine is working, it releases the heat energy of steam and converts it into mechanical energy to generate motive power; while the refrigerant in the refrigerator is used to transfer heat from low temperature to high temperature. With the improvement of global awareness of environmental protection and the increasingly stringent international requirements for reducing greenhouse gas emissions, the management of refrigerants has become particularly important.

[0004] The above patent design is a gas tank with a leakage protection function, and an automated leakage protection mechanism is designed, which can automatically start a series of protection measures when a leak occurs in the gas tank to reduce the risk of gas leakage. However, this design still relies on manual monitoring and maintenance to a certain extent, especially in terms of pressure gauge readings, and when a leak occurs in the gas tank, the design can automatically respond through a series of mechanical structures, but when the pressure exceeds the safety range, if it is not intervened manually in time, there is still a risk of overpressure or underpressure. Therefore, in view of the shortcomings of the prior art, a refrigerant storage seal detection tank anti-leakage device is designed. Utility Model Content

At the same time, the piston structure arranged in the tank body cooperates with the spring I to alleviate the pressure change inside the storage tank to a certain extent, further ensuring the stability of the system.

[0013] 2. The utility model can collect the refrigerant leaking from the pressure relief valve through the design of the collecting tank, thereby reducing environmental pollution and improving resource utilization.

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment: A refrigerant storage seal detection tank anti-leakage device, such as Figure 1-Figure 3 As shown, it includes a refrigerant storage tank 1, a pressure relief valve 2, a fixing plate 3, a tank body 4, a vent pipe I5, a vent pipe II6, a guide rod 8, a piston plate 9 and a spring I10. The refrigerant storage tank 1 is a storage container for the refrigerator. A pressure relief valve 2 is arranged on one side of the refrigerant storage tank 1. A tank body 4 is installed on the inner wall of the refrigerant storage tank 1 through a fixing plate 3. The tank body 4 is located inside the refrigerant storage tank 1. The tank body 4 is used to relieve the pressure inside the refrigerant storage tank 1. A vent pipe I5 is arranged on the lower part of the side wall of the tank body 4. The vent pipe I5 is connected to the inside of the refrigerant storage tank 1. The top of the tank body 4 is connected to a vent pipe I5. Tube II 6, the ventilation pipe II 6 passes through the outer wall of the refrigerant storage tank 1 and is connected to the outside air. A guide rod 8 is arranged at the center of the interior of the tank body 4. A piston plate 9 is slidably installed inside the tank body 4 through the guide rod 8. A piston structure is formed between the piston plate 9 and the tank body 4. A spring I 10 is arranged between the tank body 4 and the piston plate 9. The spring I 10 is used to buffer the internal pressure of the refrigerant storage tank 1; a filter screen 7 is arranged at the vent of the ventilation pipe II 6, and the filter screen 7 can filter out dust and impurities in the air to prevent dust and impurities from entering the tank body 4 through the ventilation pipe II 6, making it difficult to clean the ventilation pipe II 6 and the tank body 4.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a collecting tank 11, a baffle 12, a spring II 13 and a sealing ring 14. The collecting tank 11 is arranged on the outer wall of the refrigerant storage tank 1, and the collecting tank 11 is communicated with the pressure relief valve 2. The valve body opening of the pressure relief valve 2 is located in the collecting tank 11. A sealing ring 14 is arranged at the connection between the collecting tank 11 and the pressure relief valve 2. The collecting tank 11 is internally sealed and slidably connected with a baffle 12. There is a vacuum state between the lower part of the collecting tank 11 and the baffle 12. A spring II 13 is arranged between the baffle 12 and the top of the collecting tank 11.

[0023] like Figure 1 As shown, the outer wall of the collection tank 11 is circumferentially covered with a protective pad 15, and the protective pad 15 has certain elasticity and wear resistance, and the protective pad 15 is used to protect the refrigerant storage tank 1; the protective pad 15 is circumferentially and evenly provided with a plurality of heat dissipation holes 16, and the heat dissipation holes 16 are used to improve the heat dissipation of the protective pad 15 on the outer wall of the refrigerant storage tank 1.

[0024] like Figure 1As shown, it also includes an insulating bracket 17 and a placement plate 18. The bottom of the refrigerant storage tank 1 is installed with the insulating bracket 17, and the bottom of the insulating bracket 17 is provided with the placement plate 18. The refrigerant storage tank 1 can be stably placed on the placement surface through the placement plate 18.

[0025] When the pressure of the refrigerant in the refrigerant storage tank 1 increases due to the high external temperature, the increased air pressure inside the refrigerant storage tank 1 will enter the tank body 4 through the vent pipe Ⅰ5. When the air pressure entering the tank body 4 continues to increase, the increased air pressure will overcome the elastic force of the spring Ⅰ10 upward and squeeze the piston plate 9, so that the increased air pressure in the refrigerant storage tank 1 is released to the tank body 4 through the vent pipe Ⅰ5, thereby playing a pressure buffering role for the refrigerant storage tank 1. At the same time, when the air pressure in the tank body 4 continues to push the piston plate 9, the piston plate 9 will gradually discharge the original air in the tank body 4 through the vent pipe Ⅱ6. When the piston plate 9 overcomes the elastic force of the spring Ⅰ10 and continues to move upward, and when the spring Ⅰ10 moves to its compression limit, the increased air pressure in the tank body 4 continues to increase and breaks through the pressure release valve 2 to enter the collection tank 11. After the pressure enters the collecting tank 11, it will push the baffle 12 downward. At this time, since there is a vacuum state between the baffle 12 and the collecting tank 11 below it, under the action of the increased air pressure on the upper part of the collecting tank 11, the baffle 12 can overcome the elastic force of the spring II 13 and move downward, so that the collecting tank 11 can further collect the refrigerant released from the pressure relief valve 2 while collecting the refrigerant brought out from the pressure relief valve 2, preventing the refrigerant from directly overflowing into the external environment and causing pollution. When the refrigerant storage tank 1 is being transported, it can be placed flat on the placement surface through the placement plate 18, and the heat that may appear on the placement surface can be isolated by the insulation bracket 17 from being transferred to the refrigerant storage tank 1. At the same time, the protective pad 15 on the outer wall of the refrigerant storage tank 1 will protect it from being tipped over and provide buffering, thereby improving the safety of the refrigerant storage tank 1 during transportation.

[0026] It should be understood that the above description is only for exemplary purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
