Abstract

The invention is a device (1; 100; 200; 300; 400; 500; 600) for regulating the gas pressure and/or flow rate, comprising a 'fail close' throttling valve (2; 401; 116) positioned between a duct (A) for conveying high-pressure gas and a duct (M) for conveying gas at a lower pressure than that of the gas contained in the conveying duct (A), control means (4; 201; 301; 403; 501) of the throttling valve (2; 401; 116) provided with a pressure chamber (5; 117; 202; 302; 404; 502) in which the gas coming from the conveying duct (A) is collected, and first pressure control and regulation means (9; 405) equipped with a pipe (10; 203; 303; 406; 504) for conveying high-pressure gas to the pressure chamber (5; 117; 202; 302; 404; 502) and with means (11; 410) for connection to the outlet way (2B; 401B) of the throttling valve (2; 401; 116). The device (1; 100; 200; 300; 400; 500; 600) comprises second pressure control means (12; 101; 204; 407; 505) positioned upstream of the first control means (9; 405) and provided with a first pipe (13; 102; 205; 304; 408; 506) for connection to the first control means (9; 405), with connection ducts (14) for conveying the gas withdrawn from the conveying duct (A) of the throttling valve (2; 401; 116) to the first pipe (13; 102; 205; 304; 408; 506) and with a three-way coupling (16; 118; 207; 306) that connects the conveying pipe (10; 203; 303; 406; 504), a supply/discharge line (47; 210; 311) of the pressure chamber (5; 117; 202; 302; 404; 502) and a vent pipe (15; 103; 208; 305) for the gas contained in the pressure chamber (5; 117; 202; 302; 404; 502).
