FLOWRATE REGULATOR Russian patent published in 1994 - IPC

FIELD: power production systems. SUBSTANCE: flowrate regulator has the housing 1 with the input 2 and the output 3 branch pipes and with the partition 4, forming the output cavity 6, connected with the output branch pipe; a sensitive member in the form of the membrane 7, arranged in the housing before the partition; draining valve 9 in the form of a tubular member, whose seat is placed in the draining cavity. The cavity 5 between the housing and the membrane is joined with the input branch pipe and through the central opening 8 of the membrane with the cavity of the tubular member. That cavity is connected through side openings 17 of the tubular member with the cavity 16 between the membrane and the partition. The tubular member is mounted with possibility of axial motion in the sleeve 10, mounted in the partition. The seat of the tubular member is in the form of the disk 12, secured to the rod 13, mounted with the aid a thread joint with possibility of adjusting a position of the disc relative to the tubular member. The needle 15 is coaxially mounted on the disc 12. An upper portion of the needle 15 is arranged in the opening 8 of the membrane. EFFECT: increased accuracy, high efficiency, enhanced reliability. 3 cl, 1 dwg
