[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Example 1;

[0029] Please see Figures 1 to 6 To more conveniently control the flow rate of the outlet pipe 12, this utility model provides a technical solution: a low-pressure tank pump refrigeration circulation device. This low-pressure tank pump refrigeration circulation device mainly reduces its own noise. It includes a support frame 1 and a low-pressure circulation tank 2. The upper end of the low-pressure circulation tank 2 is detachably connected to the outlet pipe 12 for transmission. The side of the low-pressure circulation tank 2 is detachably connected to the transmission pipe 13. The upper end of the outlet pipe 12 is clamped with a control valve 14. The outer surface of the valve 14 is covered with a rubber sleeve for anti-slip. With the help of the outlet pipe 12, the refrigerant gas separated in the low-pressure circulation tank 2 is transported to the subsequent related components for further compression and other processing. With the help of the transmission pipe 13, the low-pressure circulation tank 2 is connected to other components such as the condenser 15, providing a pipeline transmission path for the flow of refrigerant between different components. The valve 14 is clamped at the upper end of the outlet pipe 12. By adjusting the opening of the valve 14, the flow rate of refrigerant gas through the outlet pipe 12 is controlled.

[0030] Example 2;

[0031] Please see Figures 1 to 4 One end of the transmission pipe 13 is threadedly connected to a condenser 15. The side of the condenser 15 is connected to an evaporator 16 via a pipe. The side of the evaporator 16 is connected to a delivery pump 17 via a pipe. One end of the delivery pump 17 is threadedly connected to an air inlet pipe 18. The side of the support frame 1 is detachably connected to a partition 3 for protection.

[0032] With the help of the condenser 15, the high-temperature and high-pressure refrigerant gas or gas-liquid mixture transported from the transfer pipe 13 is cooled, causing it to release heat and condense into a high-pressure liquid, realizing the change of refrigerant state. This prepares for subsequent throttling and pressure reduction, as well as evaporation and refrigeration in the evaporator 16. The high-pressure refrigerant liquid from the condenser 15 enters the evaporator 16 after throttling and pressure reduction. In the evaporator 16, it absorbs heat from the medium being cooled and evaporates, thereby lowering the temperature of the medium being cooled and achieving the purpose of refrigeration. This realizes the function of transferring the cooling capacity inside the refrigeration system to the external environment or object that needs refrigeration. One end of the transfer pump 17 is connected to the evaporator 16 through a pipe. It can extract the refrigerant liquid or gas-liquid mixture from the evaporator 16 and transport it to the low-pressure circulation tank 2 and other subsequent components, providing power for the circulation of refrigerant in the system. This ensures that the refrigerant can flow stably and continuously according to the predetermined refrigeration cycle path, ensuring that each component has enough refrigerant to participate in the work and maintain the normal operation of the refrigeration system.

[0033] Example 3;

[0034] Please see Figures 1 to 6To more conveniently absorb the vibration generated by the device, sound insulation cotton 4 for sound insulation is fixedly connected to the side of the partition plate 3. The side of the support frame 1 is bolted to the positioning frame 7 for support. A buffer rod 8 is inserted into the inner wall of the positioning frame 7. A spring 9 for reset is sleeved on the outer surface of the buffer rod 8. One end of the buffer rod 8 is connected to a clamping plate 10 for fixing. A threaded post 11 for fastening is inserted into the upper end of the clamping plate 10. Friction texture for anti-slip is opened on the outer surface of the upper end of the threaded post 11. A damping rod 5 for buffering is threadedly connected to the lower end of the support frame 1. A placement box 6 for positioning is threadedly connected to the lower end of the damping rod 5.

[0035] The buffer rod 8 is inserted into the inner wall of the positioning frame 7, and together with the spring 9 and other components, it forms a buffer and shock absorption system. When the device vibrates, the buffer rod 8 can slide relative to the positioning frame 7. Through its own structure and cooperation with the spring 9, it buffers and absorbs the impact force generated by the vibration, and converts the vibration energy into elastic potential energy and other forms of energy for consumption. This reduces the impact of vibration on the device as a whole and its components, protects the components from damage caused by vibration, and extends the service life of the equipment. With the help of the clamping plate 10 and the threaded post 11, the buffer rod 8 is fixed to prevent it from loosening or falling off during operation, ensuring the integrity and effectiveness of the buffer and shock absorption system.

[0036] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0037] In this invention, the working steps of the device are as follows:

[0038] First, place the device in a suitable position, then connect the positioning frame 7 to the placement box 6. At the same time, fix one end of the buffer rod 8 to the upper end of the ground through the threaded post 11, and install its partition 3 on the side of the support frame 1. Start the delivery pump 17 first. The delivery pump 17 starts working and extracts the refrigerant liquid or gas-liquid mixture in the evaporator 16 and delivers it to the low-pressure circulation tank 2 and other subsequent components to provide power for the circulation of refrigerant in the system, so that the refrigerant begins to flow in the system. The refrigerant in the evaporator 16 absorbs the heat of the cooled medium and evaporates and vaporizes into a low-temperature, low-pressure gas, which is delivered to the low-pressure circulation tank 2 through the inlet pipe 18 and other pipes. The gas-liquid mixture of refrigerant entering the low-pressure circulation tank 2 undergoes gas-liquid separation. The liquid settles at the bottom and the gas rises to the top. The separated gas is discharged through the outlet pipe 12. During the discharge process, the flow rate of refrigerant gas through the outlet pipe 12 can be controlled by adjusting the opening of the valve 14, thereby adjusting the operating state of the entire refrigeration cycle system to adapt to different refrigeration needs.
