A sugarcane tube is a hollow cylindrical structure made from the stalks of the sugarcane plant. It is commonly used as a sustainable alternative to plastic straws. Sugarcane tubes are biodegradable and compostable, making them an eco-friendly choice for consumers and businesses. They are also durable and heat-resistant, making them suitable for use in hot and cold beverages. Sugarcane tubes can be found in various sizes and colors and are often used in restaurants, cafes, and bars as a more sustainable option for serving drinks.

Expansion valve, also known as throttle valve, is the main component of automobile air conditioning and refrigeration system, installed at the evaporator inlet, as shown in Figure 15, which is the demarcation point of high and low pressure of automobile air conditioning and refrigeration system. The utility model has the functions of throttling and decompressing the high-pressure liquid refrigerant from the receiver drier, adjusting and controlling the amount of the liquid refrigerant entering the evaporator to adapt to the change of the cooling load and preventing the liquid hammering of the compressor ( That is not vaporized liquid refrigerant into the compressor after compression, can easily cause damage to the compressor valve) and the evaporator outlet steam abnormal overheating. Automotive air conditioning and refrigeration system uses temperature-sensing expansion valve, also known as thermal expansion valve, which is the use of the temperature sensor installed in the evaporator outlet to sense the refrigerant vapor superheat (superheat refers to the actual vapor temperature higher than the evaporation Temperature value), thereby adjusting the size of the expansion valve opening, thereby controlling the flow of liquid refrigerant into the evaporator. When the temperature of the evaporator is lower than the temperature of the outlet of the evaporator, the volume of the fluid in the temperature-sensing package, the capillary and the upper chamber of the membrane contracts and the expansion valve port closes to limit the refrigerant entering the evaporator. On the contrary, if the evaporator outlet temperature rises, the expansion valve opening will open. In order to increase the refrigerant flow.
