Flow limiter for fluid pipe, has adjusting unit with radial arm integrated to valve crossing oblong hole, and comprising outer sleeve with thrust shoulder in adjustable position along body to adjust position of shoulder with respect to seat

摘要

#CMT# #/CMT# The limiter has a cylindrical body (1) with a central channel on an axis. A mobile valve (8) with a seat (12) is axially arranged in the channel. An adjusting unit permits to adjust the valve with respect to the seat along a valve guide (7). The unit has radial arms (9a, 9b) integrated to the valve crossing an oblong hole (10a, 10b) of the body with an end projecting outside the body. The unit has an outer sleeve (16) with a thrust shoulder (19) at an end of the arm, where the shoulder is in adjustable position along the body to adjust the position of the shoulder with respect to the seat. #CMT#USE : #/CMT# Used for a fluid pipe for establishing adjustable restriction of passage of fluid in circulation direction and to release full passage of circulation in other circulation direction. #CMT#ADVANTAGE : #/CMT# The design of the limiter avoids precise execution constraints. The limiter chooses plastic material to obtain molding at low cost, and hence permitting to avoid a unidirectional valve. The device avoids all parts projecting from the surface of the body of the apparatus, thus reducing the encumbrance of the limiter and the risk of damage, and hence permitting a better accessibility by the operator to the adjustment of restrictions of section, while ensuring a compact limiter. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a flow limiter. 1 : Cylindrical body 7 : Valve guide 8 : Mobile valve 9a, 9b : Radial arms 10a, 10b : Oblong hole 12 : Seat 16 : Outer sleeve 19 : Thrust shoulder.
