A Review on Design and Analysis of Gate valve using Various Computer Aided Techniques
Gate valves are machine elements which are commonly used to control the flow of fluids as gate valve provides a positive sealing at high pressure of liquids and gases. Gate valves are used when a straight-line flow of fluid and minimum restriction is desired. Gate valves are so named because the part that either stops or allows flow of fluid through the valve acts somewhat like the opening or closing of a gate and is called, appropriately, the gate. The objective of this paper is to focus the design and analysis of critical components of Gate Valve. The critical components in the Gate Valve studied by many of the researchers are Body, Gate Stem and slab gate. The main purpose of design and analysis of any valve is to determine stresses and strains developed in the valve body, which is mostly done by using computer aided software tools. This paper gives detailed review on various techniques adopted by several researchers in the design and analysis of Gate valve. Generally, elements of Gate Valve are developed in CATIA and analyzed in ANSYS. Specially, Gate valve stress analysis is carried out by FEM using ANSYS which can be further validated and supported by stress analysis using classical theory of mechanics.

A Butterfly valve is a type of flow control device, which is widely used to regulate a fluid flowing through a section of pipe. This type of valve is mainly used as safety valve, turbine inlet valve, and pump valve for low to medium design pressures. They are operated by oil hydraulic systems for opening and closing or by closing weight and hydraulic pressure for opening. For turbine inlet valves, oil pressure can also be taken from the governor hydraulic oil system. The sealing system is of flexible, adjustable rubber/metal type to reduce leakage to a minimum. Water flow through the valve is possible in both directions.

As a very important element of most water supply systems, valves are exposed to the effects of strong hydrodynamic forces. When exposed to large physical quantities, the valve and piping can be damaged, which could endanger the performance of a water supply system. This is the main reason why it is necessary to foresee and determine the maximum values of velocity, pressure and other physical quantities that can occur in the system under certain conditions. Predicting extreme conditions allows us to correctly size the valve for the expected conditions to which the valve might be exposed, which is also the main objective of this paper. One of the methods for predicting and determining extreme values on a valve is to perform a simulation with computational fluid dynamics (CFD). This is exactly the method used in the preparation of this paper with the aim of gaining insight into the physical magnitudes for models of gate valves positioned inside a pipe under characteristic degrees of va...
IRJET- Finite Element Analysis of Seat Replacement Fixture for 12"-600# Gate Valve
IRJET, 2020
Gate valve is an element that controls system streamline by opening and closing fluid flow, fluctuating the amount of fluid flow and regulatory direction of fluid. The appellation of the gate is obtained by the presence of the slab gate in the streamline. Gate valves are used for controlling flow of fluid. Because of their ability to cut through liquids, gate valves are used in the industry. Valve seat is one of the main parts of the gate valve. It is used to avoid leakage of fluid, pair of valve seat gets worn after some duration so that working of valve gets affected. There is need for replacement of valve seat after some duration for good working condition of gate valve. The objective of this paper to perform a stress analysis of seat replacement fixture of gate valve. A model of each element of seat replacement fixture is developed in solid works software, and analyzed in ANSYS 11. Stress analysis is done by FEM using ANSYS 11.

All over the world, there is an urgent need for effective fluid control equipment, such needs can be found in foods, drugs, beverages, power generation, and oil and gas industries. Some of the existing equipment for this purpose has certain limitations for effective control of fluid at high pressure condition. Thus, there is a need for design modification to solve the prevailing problem. This paper majorly addressed the case peculiar to the oil and gas industries, where fluid control failure has cost millions of dollars, hazardous environmental effect and also decline in nation's economy, taking Niger Delta oil spillage as a case study. In this work, computer aided design method (CADM) was utilized to design and perform stress analysis of a high pressure gate valve used on a typical oil and gas wellhead of working pressure up to 15,000 psi. (103.4 MPa). The critical components in the gate valve are the body and gate (disc). Conversional design adopts calculations from analytical method, but in this work, finite element analysis (FEA) was used to determine stresses and deformations distribution on critical components of the high pressure gate valve (HPGV) as they are the main pressure retaining boundaries in the valve. The results obtained from the two methods indicated reasonable convergence after validation. The stress analysis conducted was based on von mises failure criterion which is most suitable for ductile materials. The results obtained from both analytical design calculation and that of finite element analysis indicates reasonable agreements by measuring their percentage performance variance. Therefore, the findings of this research work attests to reliability of the designed HPGV valves in meeting engineering design assessments, and in turn can be optimally advanced in the manufacture of high pressure gate valves.
