Author: Dr. Gurudutt Sahni
Subject: Mechanical Engineering / Pressure Vessel & Piping Design
1. Introduction
Industrial globe valves are critical for flow regulation but are often susceptible to high-intensity transient loads—such as seismic events, water hammer, or explosive shocks. This paper outlines the methodology for ensuring structural integrity under high-G environments through rigorous shock testing and design criteria.
2. Design Criteria for Shock Resistance
To ensure a globe valve remains functional during and after a shock event, the following criteria must be met:
- Structural Integrity: The pressure-retaining boundary (body and bonnet) must not rupture.
- Operability: The stem must not bend, ensuring the valve can still open or close.
- Seat Tightness: The plug-to-seat alignment must remain intact to prevent internal leakage.
- Frequency Decoupling: The fundamental natural frequency of the valve assembly should ideally be higher than the dominant shock pulse frequency (typically > 33 Hz for seismic applications).
3. Design Formulas & Formulations
The design of a shock-proof valve relies on calculating the Equivalent Static Force (F_s) generated by a shock pulse.
Acceleration and Force
The primary design load is calculated using the Peak Acceleration (A_p) from the Shock Design Envelope:
