Description

TECHNICAL FIELD

[0001] The utility model relates to spring sealing piece technical field, concretely is a spring energy storage ring. BACKGROUND

[0002] Spring energy storage ring, namely spring energy storage sealing ring, is composed of polymeric material sealing shell and corrosion-resistant stainless steel spring, the sealing ring is installed in the groove, the spring is compressed, the outward tension is formed, the sealing lip is tightly attached to the sealing groove, the spring provides the spring energy to the sealing lip permanently, the wear and tear of the sealing shell and the eccentricity of the matched parts are compensated, and thus the sealing from the vacuum to the low pressure range is formed. In addition, the system pressure will assist the spring energy storage, the greater the pressure, the more sufficient the sealing lip and the groove are attached, and thus the high pressure sealing is formed.

[0003] In the prior art, the authorized patent with publication number CN221003758U discloses a spring energy storage ring, which comprises a sealing shell, a spring groove is formed in the sealing shell, a metal spring is arranged in the spring groove, a protective layer is arranged on the inner wall and the outer wall of the sealing shell, a plurality of blocking strips are arranged on the front side wall of the sealing shell, the blocking strips are annularly and equidistantly distributed, and one end of the blocking strip is fixedly bonded to the outer wall of the sealing shell on one side of the spring groove. During use, when the spring energy storage ring is installed, the blocking strip can be pulled, the blocking strip stretches, the buckle groove formed at the end is buckled on the buckle rod, thereby forming a blocking effect on the metal spring in the spring groove, avoiding the metal spring from rolling in the spring groove due to its own tension, causing the metal spring to fall off from the sealing shell, affecting the sealing effect of the spring energy storage ring, and the blocking piece can prevent the blocking strip from sliding out of the buckle rod.

[0004] However, the above technical solution still has the following disadvantages in actual use: the above device limits the spring in the spring groove by buckling the blocking strip and the buckle rod, which has the disadvantages of troublesome assembly and inability to comprehensively protect the spring in the spring groove. To solve the above problems, we propose a spring energy storage ring. UTILITY MODEL CONTENTS
