Performance study of a diaphragm type crankcase pressure control valve
Pressure control valve (PCV) is implemented in internal combustion engine to regulate crankcase pressure. In this study, the performance of a diaphragm PCV valve is investigated numerically and experimentally. Firstly, numerical simulation is carried out using commercial code to predict the flow and pressure distribution inside the valve. Furthermore, downstream and upstream pressure of the val...
متن کاملBrazilian tracheotomy speech valve: diaphragm pressure standardization.
UNLABELLED Tracheotomy is performed in cases of upper airway obstruction or chronic pulmonary disorders. The Tracheotomy Speech Valves (TSV) improve communication and airway hygiene and humidification of tracheotomized patients. AIM To show the low cost Brazilian TSV and its use in speech rehabilitation of tracheotomized patients, to evaluate diaphragm opening resistance and comfort to the pa...
متن کاملDynamic Behaviour of Hydraulic Pressure Relief Valve
This paper discusses the influence of the radial clearance of the poppet of the direct spring operated pressure relief valve type DPRS06K315 on the dynamic behaviour of the valve. The mathematical model of the valve has been developed; these mathematical terms have been represented in Matlab/SIMULINK. The results obtained by a simulation describe dynamic behaviour of the valve and its influence...
متن کاملDynamic Analysis of Hydraulic Pressure of Relief valve
AbstractPressure relief valve is one of the most important devices used on the security of pipelines, since it is responsible to guarantee the integrity of the installations. Generally, the response and behaviour of a relief valve during its transient is unknown by users, who employ simplified and static analysis to design the pipeline, further, the information provided by manufactures is limit...
متن کاملDynamical Analysis of a Hydraulic Pressure Relief Valve
A mathematical model is derived that describes the dynamics of a single stage relief valve embedded within a simple hydraulic circuit. The aim is to capture the mechanisms of instability of such valves, taking into account both fluid compressibility and the chattering behaviour that can occur when the valve poppet impacts with its seat. The initial Hopf bifurcation causing oscillation is found ...
