ANALYTICAL STUDY OF HYDRAULIC PRESSURE CAUSED BY LIQUID IN GATE VALVES

Abstract

There is an urgent need worldwide for efficient fluid control equipment. Some of the existing equipment has certain limitations for efficient fluid control under high pressure conditions. Thus, design modifications are required to solve this problem. This article presented a analytical method for designing and performing stress analysis for a high pressure valve used on a typical oil and gas wellhead with operating pressures up to 100 MPa. The most important components of a valve are the body and the valve (disc). The conversion design uses analytical method calculations to determine the stress and strain distribution in the critical components of a high pressure valve. Results from both analytical computational design and finite element analysis indicate reasonable agreement by measuring percent performance variance. Thus, the results of this research work confirm the reliability of the designed valves in accordance with engineering design estimates and, in turn, can be optimally improved in the manufacture of high pressure valves. Keywords: gate valve, analytical method, validation, design and high pressure.
