Description
Technical field
The utility model relates to a kind of modulating valve, specifically a kind of high pressure cage angle type control valve.
Background technique
Modulating valve in hyperbaric environment because the noise that the Complex Phenomena in Vertical Bell Jar such as ubiquity turbulent flow, separated flow produces in the valve pocket of valve, runner is very large, how balance and noise reduction with reduce flow loss, avoiding the generation in new turbulence noise source, is cage type regulating valve main problem that design faces.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of high pressure cage angle type control valve.
The technical solution of the utility model is:
A kind of high pressure cage angle type control valve, comprise valve body, valve gap, valve rod, mangetic core assembly, described valve body upper end is by being fixedly connected with the valve gap that has central passage, described valve seat is located in body cavity, described valve seat is provided with the mangetic core assembly being mated, described mangetic core assembly is fixedly connected on one end of valve rod, the other end of described valve rod stretches out outside valve gap through central passage, in the space of the central passage composition of described valve rod and valve gap, be provided with filler, described filler is provided with Gland, described Gland is bolted on valve gap, it is characterized in that: the outside of described mangetic core assembly is provided with sleeve, described sleeve is placed on the upper-end surface of valve seat.
In described mangetic core assembly, be embedded with elasticity C type ring, in mangetic core assembly groove, embed successively from inside to outside expanding ring, guide ring.
Between described valve body and valve gap, be provided with stainless steel serrated seal circle, between described valve body and valve seat, be provided with graphite wound gasket.
The type of described filler is the graphite establishment filler that graphite and nickel are made.
The beneficial effects of the utility model are:
The utlity model has the advantages such as droop loss is little, flow is large, adjustable extent is wide, Flow characteristics precision is high, dynamic stability is high, noise is low, cavitation corrosion is little.
