The expansion valve functions as a throttling and depressurizing. When the high-pressure refrigerant liquid condensed by the condenser passes through the throttle valve, the pressure is lowered due to the resistance, resulting in partial vaporization of the refrigerant liquid, while absorbing the latent heat of vaporization, and its own temperature. It is also reduced accordingly, becoming a low temperature and low pressure wet steam, and then entering the evaporator. Unlike the check valve, a check valve is used in the central air conditioner.
A hydraulic fastening tool is a type of power tool that uses hydraulic pressure to quickly and efficiently fasten or loosen nuts, bolts, and other fasteners. It is commonly used in industries such as construction, automotive, and manufacturing.
The tool consists of a Hydraulic Pump that generates pressure, a Hydraulic Hose or line to transmit the pressure, and a hydraulic cylinder or motor that applies the pressure to the fastener. The tool may also have various attachments or sockets to fit different sizes and types of fasteners.
Hydraulic fastening tools are known for their high torque output, allowing them to handle heavy-duty fastening applications. They are often used in situations where manual or electric tools are not sufficient, such as when dealing with rusted or stubborn fasteners.
Some advantages of hydraulic fastening tools include:
1. Speed and efficiency: Hydraulic tools can quickly apply high torque, reducing the time and effort required for fastening or loosening tasks.
2. High torque output: Hydraulic tools have a high torque output, making them suitable for heavy-duty applications that require a lot of force.
3. Versatility: Hydraulic fastening tools can be used with various attachments and sockets, allowing them to handle different sizes and types of fasteners.
4. Portability: Many hydraulic fastening tools are compact and lightweight, making them easy to transport and use in different locations.
5. Durability: Hydraulic tools are typically built to withstand heavy use and harsh working conditions, ensuring long-lasting performance.
Overall, hydraulic fastening tools are a reliable and efficient option for professionals who need to quickly and securely fasten or loosen nuts, bolts, and other fasteners.
