Description
Technical field
This utility model relates to valve technology field, particularly a kind of choke valve.
Background technology
Choke valve is made by changing valve port flow area or passage length and hinders to the variable liquid changing resistance, in hydraulic circuit, and liquid
The flow passed through is provided constraints by resistance, and therefore, choke valve can be with speed governing.The contour structures of choke valve and stop valve indistinction,
Simply the shape of they opening and closing elements is different.It is streamlined that the opening and closing element of choke valve is mostly circular cone, changes channel cross-section by it
Amass and reach to regulate flow and pressure.Choke valve is used for making to reduce pressure medium in the case of greatly in pressure drop.
During choke valve uses, when fluid media (medium) enters in valve pocket by choke valve entrance, owing to passage diminishes suddenly, stream
The flow velocity of body increases suddenly, and pressure declines, and fluid at a high speed produces the biggest impulsive force to spool and valve seat.This impact causes
Valve rod constantly vibrates, and has the strongest erosion ability to spool and valve seat, and, spool is relative to valve body, and spool is general
For taper or spherical, hydraulic power can be produced when fluid is by valve port, cause the self-excitation of valve to shake, and then have influence on whole system
Stability and reliability.
Therefore, how to allow throttle valve core balance pressure and impulsive force, extend valve body service life, this is the most urgently to be resolved hurrily
Problem.
