Abstract

The present invention relates to low-temperature refrigeration, and provides a two-way phase-adjustable valve, including a high-pressure valve control assembly, a low-pressure valve control assembly, a cam assembly, a swing rod assembly, a plug assembly, and a rotary valve body; and also provides a pulse tube expander, including The above-mentioned valve; and a refrigeration system including the above-mentioned pulse tube expander is also provided. In the present invention, by driving the motor to control the rotation of the cam assembly, the high-pressure gas generated by the compressor can enter the hot end of the pulse tube and the cold end of the pulse tube respectively through the two first flow paths, and the hot end of the pulse tube can be adjusted through the valve during the process. The opening sequence with the cold end, and then realize the expansion and cooling of the gas in the pulse tube. The whole process is not only convenient to control, high in reliability, but also very high in expansion efficiency.

Description

technical field [0001] The invention relates to low-temperature refrigeration, in particular to a two-way phase-adjustable valve and a pulse tube expander. Background technique [0002] In recent years, with the rapid development of cryogenic equipment, the requirements for the core component expander to realize low temperature environment are also increasing. With the development and improvement of thermoacoustic theory, phase theory, and gas piston theory, people have a deeper understanding of the principle of gas oscillation and cooling in the pulse tube. On this basis, the pulse tube expander successfully realizes the process of gas expansion and cooling through the pulse tube, and uses the cooling capacity of the gas after cooling to achieve a low temperature environment. [0003] The pulse tube expander can control the phase of gas pressure and flow inside the pulse tube only through the valve, and then make the gas flow alternately in the pulse tube. When the phase d...
