DEVICE FOR CONTROL OF FLOW RATE

摘要

FIELD: fluid-pressure automatics. ^ SUBSTANCE: device comprises tubular housing and spring-loaded self-centering sensor made of a truncated cone. The sensor and housing define a ring slot that converges in the direction of flow. The baffle inside the housing has throttling slot. The pipe is connected to the sensor at its center. A part of the pipe is made for permitting cooperation with the relief space downstream of the throttling slot. The inlet space of the housing is connected with the space upstream of the throttling slot through the by-pass that receives the throttling device made of a nozzle to define varying throttling cross-section. ^ EFFECT: enhanced precision. ^ 1 cl, 1 dwg
