High pressure and temp. reduction valve - has staggered rows of throttle apertures, to allow for unhindered flow generation

摘要

The valve is for fluids at high pressure and temperature. It has a cylindrical valve housing, with a throttle slide, consisting of chambers and surrounding throttle sleeve. Rows of apertures (20) in the throttle chamber sleeve (19) act as throttle bores. They are located upstream of the inner annular chamber (17), at the point of inter-section of the ring-shaped rows, with parallel generating lines of the throttle sleeve. Two or more of the generating lines are combined to a group, and associated rows of apertures are staggered relative to each other, until the apertures overlap. The generating lines groups are central symmetrical.
