Compressor cylinder cover with good tightness

Abstract

The invention discloses a compressor cylinder cover with good tightness. The compressor cylinder cover comprises a cylinder cover main body, a pressing ring is integrally formed at the middle positioninside the cylinder cover main body, a first rubber sleeve is arranged on the outer surface of the cylinder cover main body, a groove is formed in the upper surface of the cylinder cover main body, asliding groove plate is welded at the bottom end inside the groove, a protective pad is placed inside the groove, and four connecting holes are formed in the middle of the protective pad. Since the protective pad is designed inside the groove, so that the problem that the cylinder cover is inconvenient to protect and easily touches the outer surface of the cylinder cover during transportation, and therefore the cylinder cover is not tightly installed and deflated during installation and use is avoided, the outer surface of the cylinder cover main body can be protected by the first rubber sleeve, and when the protective pad touches the upper surface of the cylinder cover main body, a sliding head slides inside a sliding groove plate through the action of elastic deformation of the spring to buffer the protective pad, and at the moment, the upper surface of the cylinder head main body is protected by the protective pad.

Description

technical field [0001] The invention belongs to the technical field of cylinder heads, and in particular relates to a cylinder head for a compressor with good airtightness. Background technique [0002] The function of the existing compressor cylinder head is to seal the compressor cylinder, form a combustion space together with the piston, and bear the effect of high temperature and high pressure gas. The cylinder head bears the mechanical load caused by the gas force and tightening the cylinder bolts, and also bears a high thermal load due to the contact with the high-temperature gas. In order to ensure good sealing of the cylinder, the cylinder head can neither be damaged nor deformed. For this reason, the cylinder head should have sufficient strength and rigidity; the existing cylinder head is not easy to protect and easy to touch the outer surface of the cylinder head during transportation. , resulting in the cylinder head not being tightly installed during installatio...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a cylinder head for a compressor with good airtightness, so as to solve the problem that the existing cylinder head is not convenient for protection and easy to touch the outer surface of the cylinder head during transportation, causing the cylinder head to be damaged. When installed and used, the installation is not tight and the air is leaked. When used for a long time, the rubber pad is easy to wear and damage, resulting in air leakage. It is not convenient for the protection of the rubber pad and the problem of better sealing during installation.
