Abstract
The invention concerns a device for controlling a fluid flow, characterised in that said device comprises second valve arrangement means interposed in the circuit in series with first valve arrangement means (20, 22, 34), and wherein a second mobile closure element (38) moves between a pressing position, wherein it is pressed on the seat (32) of a second threshold (30) and an opening position wherein the second closure element (38) is spaced apart from the second seat (32) to allow the fluid through the second threshold (30), and in pressing position, the second closure element (38) allows a reduced flow of the fluid through the second threshold (30).
Claims10
A device to control a flow of fluid, comprising:
- first valve regulation means having a first threshold through which the fluid circulates, and a first movable stop plug that moves inside a chamber between a first seated position, in which the first movable stop plug rests on a first seat to interrupt passage of the fluid through the first threshold, and a first open position, in which the first movable stop plug is separated from the first seat to enable passage of the fluid through the first threshold;
- and
- second valve regulation means having a second threshold and a second movable stop plug;
- wherein the second valve regulation means are placed in series with the first valve regulation means;
- wherein the second movable stop plug moves between a second seated position, in which the second movable stop plug rests on a second seat of the second threshold, and a second open position, in which the second movable stop plug is separated from the second seat to allow for passage of the fluid through the second threshold;
- and
- wherein, in the second seated position, the second movable stop plug allows for passage of a reduced flow of the fluid through the second threshold.
