Abstract
A pressure regulator for fluids is described. The pressure regulator (100) has a main body (108) including a control valve (112,113) actuated by a control element (119) responding to a pressure signal generated by sensor means (118) to maintain a set pressure in the transfer line. The main body (108), the control valve (112,113), the control element (119) and the sensor means (118) are contained in an interior space (124) enclosed by a housing (123). A pressure below atmospheric pressure prevails in the interior space (124).
Claims7
A pressure regulator for fluids, wherein the pressure regulator comprises:
- a main body including a control valve actuated by a control element responding to a pressure signal generated by sensor means to maintain a set pressure in a transfer line,
- wherein the main body, the control valve, the control element and the sensor means are contained in an interior space enclosed by a housing, and
- wherein the transfer line is a multiwalled transfer line, wherein the housing is connected with an outer tube of the multiwalled transfer line such that a space enclosed between the outer tube and an inner tube of the multiwalled transfer line is fluidly connected with the interior space of the housing such that a pressure below atmospheric pressure prevails in the interior space.
