Abstract

The invention discloses an on-line regulation device of an expansion machine of a split type stirling cryocooler. The on-line regulation device comprises a regulating stem, wherein one end of the regulating stem can be connected with a spring fixing seat of the expansion machine, a self-sealing seat is installed on the periphery of the regulating stem, an outer fixing seat is installed on the periphery of the self-sealing seat, and the outer fixing seat is provided with a bolt hole which is used for being connected with an air cylinder of the expansion machine; and the other end of the regulating stem is stretched out of the end portion of the outer fixing seat and the end portion of the self-sealing seat to form a stretched regulating portion. The on-line regulation device can achieve on-line parameter regulation during testing processes of the cryocooler, can improve debugging efficiency, shortens the development cycle of the stirling cryocooler, and is simple in structure, convenient to operate and low in manufacturing cost.

Description

technical field [0001] The invention relates to an online regulating device, in particular to an online regulating device applicable to an expander of a split Stirling refrigerator. Background technique [0002] The Stirling refrigerator is a gas recuperation closed-cycle refrigerator that works according to the reverse Stirling cycle. It has the advantages of compact structure, wide working temperature range, quick start, high efficiency, reliability and durability, and is now widely used in aerospace, superconducting, infrared detection and other fields, in missile guidance, infrared forward vision and night vision, thermal imager It has played an important role in military and civilian equipment. [0003] Stirling refrigerators are divided into integral refrigerators and split refrigerators. The split Stirling refrigerators are piston-displacer refrigerators composed of two separate reciprocating cylinders. The discharge in the expander cylinder The actuator has no mech...
