Abstract
The invention discloses a notch sphere of a four-way ball valve. An outlet end is located on the side surface of the sphere, the outlet end and an inlet end form an L-shaped channel, two sides of a sphere opening of the outlet end are provided with notches, each of the notches is in an arc M shape, the radius of the arc M is R, the R is in a range from 10mm to 800mm, the distance between the R and the ball valve center E is in a range from 5mm to 300mm, and the radian theta of the arc M is in a range from 30 degrees to 90 degrees. The notch sphere has the advantages that scouring for the sphere and the valve seat is reduced, ball valve actuation sealing inner members are well protected, the service life of the ball valve is prolonged, and the notch sphere is suitable to harsh working conditions such as two-phase flow or multiphase flow.
Description
Technical field
The present invention relates to a kind of spheroid, particularly a kind of breach spheroid of four way ball valve.
Background technique
Tradition four way ball valve spheroid under advance side and go out, as shown in Figure 1, mainly form by entrance point, outlet end and spheroid.Entrance point is used for charging in the bottom surface of spheroid.Side and entrance point that outlet end is positioned at spheroid form L type passage, are used for discharging.Be 120 degree, three passages that distribute on the valve body, the outlet end through the program control spheroid aligns with three passages of valve body, can be implemented in the time that needs to carry out the discharging switching.Spheroid diameter of its circulation in handoff procedure is to the all-pass footpath from zero.When if fed sheet of a media is two-phase or multiphase stream; Spheroid is when the initial unlatching of switching and switching are about to put in place, and the cross section of circulation is very little selenodont, so flow velocity is very high; Fluid produces the passway of spheroid and valve seat and strong wash away and wear and tear, and has shortened the working life of ball valve greatly.Therefore, traditional four-way spheroid is not suitable for harsh operating modes such as two-phase or multiphase stream.
Summary of the invention
Technical problem to be solved by this invention is that a kind of breach spheroid that improves the four way ball valve in ball valve life-span will be provided.
In order to solve above technical problem, the invention provides a kind of breach spheroid of four way ball valve, side and entrance point that outlet end is positioned at spheroid form L type passage, and said outlet end ball mouth both sides are provided with breach.
Said breach is camber line M shape, and the radius of camber line M is R, and R is at 10mm～800mm; E is 5mm～300mm to R apart from the ball valve center; The radian θ of camber line M is 30 °～90 °.
It is the great technological innovation to traditional four way ball valve spheroid that outlet end ball mouth both sides are provided with breach; Change and adjusted fluid flow morphology during through the runner mouth in switching process, circulation area is extended to three times, through the diffusion fluid; Flow velocity reduces; Thereby obvious reduction is washed away spheroid and valve seat, has protected ball valve motive sealing internals greatly, the working life of having improved ball valve.Therefore, the breach spheroid of four way ball valve of the present invention is applicable to harsh operating modes such as two-phase or multiphase stream.
Superior effect of the present invention is:
1) after outlet end ball mouth both sides of the present invention (90 degree and 270 degree positions) were provided with breach, obvious reduction was washed away spheroid and valve seat, has protected ball valve motive sealing internals greatly, the working life of having improved ball valve;
2) the breach spheroid of four way ball valve of the present invention is applicable to harsh operating modes such as two-phase or multiphase stream.

Embodiment
See also shown in the accompanying drawing, the present invention is done further description.
As shown in Figure 2, the invention provides a kind of breach spheroid of four way ball valve, side and entrance point that outlet end 1 is positioned at spheroid 2 form L type passage, and said outlet end 1 ball mouth both sides are provided with breach.
Said breach is camber line M shape, and the radius of camber line M is R, and R is at 10mm～800mm; E is 5mm～300mm to R apart from the ball valve center; The radian θ of camber line M is 30 °～90 °.
Entrance point of the present invention generally is used for charging in the bottom surface of spheroid.Side and entrance point that outlet end 1 is positioned at spheroid form L type passage, are used for discharging.Be 120 degree, three passages that distribute on the valve body, the outlet end 1 through the program control spheroid aligns with three passages of valve body, can be implemented in the time that needs to carry out the discharging switching.Outlet end 1 ball mouth both sides, promptly 90 degree and 270 degree positions are provided with breach, and R is the radius of breach camber line M, and θ is the arc of camber line M---and E is that R is apart from the ball valve center.It is to the great technological innovation of the spheroid of traditional four way ball valve that outlet end 1 ball mouth both sides are provided with breach; Change and adjusted fluid flow morphology during through the runner mouth in switching process, circulation area is extended to three times, through the diffusion fluid; Flow velocity reduces; Thereby obvious reduction is washed away spheroid and valve seat, has protected ball valve motive sealing internals greatly, the working life of having improved ball valve.Therefore, the breach spheroid of four way ball valve of the present invention is applicable to harsh operating modes such as two-phase or multiphase stream.
Claims (2)
