AI Technical Summary
Technical Problem
The insertion of a sealing plug into a discharge refrigerant pipe is hindered by misalignment of central axes, leading to poor workability and inadequate adhesion, compromising the airtightness.
Method used
A sealing plug with a stepped hole structure, featuring a large diameter portion at the base and a smaller diameter portion at the tip, ensures proper alignment with the dedicated jig, facilitating easy insertion and enhancing airtightness by minimizing gaps between the plug and the pipe.
Benefits of technology
The stepped hole design improves workability and ensures airtight sealing by maintaining alignment with the pipe, preventing gaps and ensuring reliable adhesion, thus enhancing the sealing plug's effectiveness.

Abstract
To ensure ease of insertion of the sealing plug and to guarantee the airtightness of the sealing plug. [Solution] The sealing plug for compressor equipment is a sealing plug capable of sealing the opening on one end of a connecting pipe for connecting a compressor equipment which constitutes part of a refrigeration cycle mechanism to other equipment which constitutes a refrigeration cycle mechanism. The sealing plug has a sealing plug body that seals the opening on one end of the connecting pipe when the sealing plug is attached to the connecting pipe, and a hole that is formed along the length of the sealing plug and extends partway from one end face of the sealing plug. The sealing plug body has a large diameter portion located on the base end side of the sealing plug body, and a small diameter portion located on the tip side of the sealing plug which is smaller than the large diameter portion and has an outer diameter smaller than the outer diameter of the large diameter portion. The diameter of the hole is set to be smaller on the tip side which is on the opposite side of the base end than on the base side which is on one end face of the sealing plug, and the tip of the hole is located within the region of the small diameter portion in the length direction.
