Putting, medium cannot circulate, and regulation ball valve is closed.
When the regulation ball valve of the present embodiment offer is half-open, as it is shown on figure 3, valve rod 3 drives spheroid 4 to be in half-open position, ball
Plate of facing the wall and meditating contacts with valve seat 6, counteracts the out-of-balance force of spheroid 4 and valve seat 6, eliminates regulation ball valve and produces during stroke
Raw additional moment；After medium enters the runner of spheroid 4, the valve core through hole from spool 5 enters spool 5, and flow velocity reduces, due to
The track of valve core through hole is tortuous, medium circulate in the interior process of circulation track occur repeatedly bend, velocity of medium is further
Reducing, last medium flows out to media outlet after entering the wallboard through hole on sphere wallboard.
According to different actual conditions, the quantity of scalable sphere wallboard wainscot through hole, size, shape, and spool 5
On the quantity of valve core through hole, size, shape, track meet concrete duty requirements.This regulation ball valve under different apertures,
Along with the rotation of spheroid 4 with spool 5, the circulation area of medium changes therewith, changes the flow resistance coefficient of regulation ball valve, optimizes
The flow-adjusting characteristics of regulation ball valve, improves degree of regulation.Wallboard through hole on sphere wallboard and the valve core through hole on spool 4
Setting, while serving decompression and throttling action, also solve regulation ball valve height when working under High Pressure Difference operating mode and make an uproar
Sound and strong vibration problem, reduce the energy expenditure of valve, improves the working environment of operator.
Sphere wallboard, is under half-open duty when regulating ball valve as regulation internals while Flow-rate adjustment
Time, sphere wallboard contacts with valve seat 6, counteracts the out-of-balance force of spheroid 4 and valve seat 6, eliminates regulation ball valve in stroke
The additional moment of middle generation, it is to avoid cause executor excessive because of additional moment, and cause valve seat 6, the spheroid 4 to wear and tear
Problem, extends the service life of valve.
The above, only two kinds of detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto,
Any those familiar with the art, in the technical scope that the invention discloses, can readily occur in change or replace,
Should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be with described scope of the claims
It is as the criterion.
