Abstract

The invention relates to a one-way limit damping guide slot, which comprises a fixed support. At least one guide slot is formed on the fixed support; buffer rubber is arranged on the bottom part of the guide slot, and is made of high-temperature-resistant silica gel. Through the specially designed buffer element, the one-way damping guide slot can meet the limit requirement of a valve body.

Description

technical field [0001] The invention relates to a one-way limiting damping guide groove, which belongs to a groove-shaped damping mechanism. Background technique [0002] When the valves used in the nuclear power piping system are subjected to the basic vibration and impact of the nuclear power piping system, due to the excessive impact displacement, it is easy to cause damage to the valve. Due to the particularity of the valve structure, it is difficult for the commonly used limit structure to meet the impact resistance requirements of the valve body. [0003] According to the structural characteristics of the valve body, the groove-shaped limit guide groove is adopted, and the buffer material is added in the guide groove. When the valve body structure has a large displacement, it can effectively protect the valve body structure. Through the design of the protrusion structure, while the valve body is buffering, other parts do not contact with the guide groove parts, which ...
