Abstract
The utility model discloses a kind of high-pressure low-noise cage type regulating valve, comprise valve body, valve seat, valve rod, mangetic core assembly, it is characterized in that: the fluid outlet in valve seat lower end is provided with throttle element, described valve body upper end is fixedly connected with the valve gap that has central passage, between described valve body and valve gap, be provided with sleeve, on described sleeve, be provided with many symmetrical apertures, described sleeve is located in the outside of mangetic core assembly and is placed on the upper-end surface of valve seat.High-pressure low-noise cage type regulating valve of the present utility model is for adapting to gas throttling diffusion and expanding, and the aperture that is provided with many symmetries on sleeve reduces pressure and noise; On valve body below valve seat, be provided with a throttle element, the noise that can well reduce the pressure of fluid and under high pressure produce.
Description
Technical field
The utility model relates to a kind of modulating valve, specifically a kind of high-pressure low-noise cage type regulating 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 low-noise cage type regulating valve.
The technical solution of the utility model is:
A kind of high-pressure low-noise cage type regulating valve, comprise valve body, valve seat, valve rod, mangetic core assembly, it is characterized in that: described valve seat is placed on the flat gasket in the valve seat orifice of valve body, the fluid outlet of described valve seat lower end is provided with throttle element, described valve body upper end is fixedly connected with the valve gap that has central passage, between described valve body and valve gap, be provided with sleeve, described sleeve is provided with many symmetrical apertures, described sleeve is located in the outside of mangetic core assembly and is placed on the upper-end surface of valve seat, stretch out outside valve gap through central passage the upper end of described valve rod, described valve rod lower end is connected with mangetic core assembly, described valve rod and valve gap upper wall joint are provided with balance spring, described balance spring below is provided with pad, described balance spring is provided with filler, described filler is provided with Gland.
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 the first stainless steel serrated seal circle, between described valve body and sleeve, be provided with the second stainless steel serrated seal circle.
The beneficial effects of the utility model are:
High-pressure low-noise cage type regulating valve of the present utility model is for adapting to gas throttling diffusion and expanding, and the aperture that is provided with many symmetries on sleeve reduces pressure and noise; On valve body below valve seat, be provided with a throttle element, the noise that can well reduce the pressure of fluid and under high pressure produce.
