Product Details
In the complex structure of a refrigerator, the compressor valve plate plays a crucial role, serving as a core component that ensures efficient refrigeration. Its ingenious design mainly consists of the valve plate body, suction and discharge valve ports, and sealing components.
The valve plate body, as the foundation of the entire valve plate structure, is usually made of high-strength, corrosion-resistant metallic materials such as stainless steel. This is because during the operation of the compressor, the valve plate must withstand high temperatures, high pressures, and the chemical properties of the refrigerant. Metallic materials ensure that the valve plate maintains stable physical and chemical properties under harsh operating conditions, preventing deformation or damage, and thus maintaining a long-term reliable working state.
The suction and discharge valve ports are the key parts of the valve plate that enable its core function. The suction valve port is responsible for opening the passage when the compressor piston moves down, allowing low-temperature, low-pressure refrigerant gas to smoothly flow into the cylinder, providing "raw materials" for the refrigeration cycle. The discharge valve port opens when the piston moves up, discharging the high-temperature, high-pressure refrigerant gas from the cylinder, driving the continuous operation of the refrigeration cycle. The size, shape, and number of these valve ports are carefully designed and optimized to meet the working needs of different compressor models, ensuring smooth and efficient gas flow. For example, some high-performance refrigerator compressors use special streamlined valve port designs to significantly reduce the resistance of gas entry and exit, effectively improving the compressor's gas delivery efficiency.
