Static error of a pressure regulator for liquid propane-butane Dragoljub Vujić Slobodan Radojković A mathematical model of the regulator behaviour in a
steady state has been derived. The model presents the dependence between the
output pressure and the flow and the input pressure as well as the regulator
construction parameters. The influence of the construction parameters on the
static error has been discussed. In a numerical example, the static
characteristic, the static error, the pressure and the airproof sealing force
have been determined for one type of the regulators.
