Embodiment
Sleeve adjusting valve as shown in Figure 2 comprises valve body 1, valve seat 3, sleeve 4, valve plug 16, valve rod 9, valve gap 12, filler 13 and hold-down grid 10.
Wherein, sleeve 4 vertically is arranged in the inner chamber of runner, be stacked on the valve seat 3 in valve body 1 inner chamber, valve plug 16 is positioned at sleeve 4, this sleeve 4 constitutes by lower sleeve 41, upper bush 42 are stacked, wherein has the through hole 411 that is communicated with runner on the sidewall on the lower sleeve 41, the bevel sealing surface 31,161 of on the valve seat 3 and valve plug 16 bottoms limit, lower end of valve plug (specifically) sealing that cooperatively interacts when having at valve closing.Have along the breach on limit, hole in upper bush 42 backing lower ends, this breach forms groove 43 when upper bush 42 combines with lower sleeve 41; Be placed with seal ring 5 in this annular groove 43, sealing circle 5 is sealed and matched with the circumferential surface formation of valve plug 16.Upper bush 42 upper ends are fixed on the valve gap 101 of valve body 1, and valve gap 12 is pressed on the upper bush 42, and are connected on the valve body 1 by bolt and nut component.For further sealing, be provided with between described valve gap 12 and the valve body 1 between spirotallic gasket 15 and valve seat 3 and the valve body 1 and be provided with spirotallic gasket 2.
Valve rod 9 one ends are connected on the valve plug 16, and the other end stretches out from valve gap 12, and stuffing box 121 middle and upper parts and the bottom that form between the axis hole of valve rod 9 and valve gap 12 are provided with guide sleeve 14, and the middle part is filled with filler 13.Described hold-down grid 10 is connected on the valve gap 12 by clip 11 and bolt and nut component filler is compressed.In the using process, can be by regulating the impacting force that bolt and nut is regulated 10 pairs of fillers of hold-down grid.
Adopt technique scheme, the bevel sealing surface of generally acknowledging sleeve adjusting valve sleeve 4 and valve plug 16 tops is sealed and matched makes seal ring 5 into and cooperate with valve plug 16 circumferential surfacies and seal, replace the metal hard-sealing between the bevel sealing surface of sleeve bevel sealing surface of the prior art and valve plug with the soft seal between seal ring 5 and valve plug 16 circumferential surfacies, improved leakage class, saved the grinding work at sealing position, and the convenience that the assembling of giving valve brings, help the exchange of valve parts simultaneously, reduced the cost of valve
In order to make this sleeve adjusting valve have stable stroke, to improve the accuracy that valve is carried out.Described valve rod 9 lower ends have one section step 91 thicker than valve rod other parts, and the axis hole bottom of valve gap also has the aperture stop step 122 suitable with valve rod 9 diameters.The distance of step 91 upper-end surfaces of the lower end surface of this stop step 122 and valve rod 9 just in time is exactly the stroke distances of sleeve adjusting valve.
More than be that sleeve adjusting valve is the one-level sleeve adjusting valve, pressure reduction was probably at 30Kgf/cm before and after the one-level sleeve adjusting valve can only adapt to valve
2The operating mode occasion, can not adapt to 30Kgf/cm
2Above operating mode occasion.Therefore in order to adapt to the operating mode occasion of higher valve front and back pressure reduction, in the described further improvement of the utility model, described sleeve 4 has multilayer, concrete way as shown in Figure 3 and Figure 4, lower sleeve 41 is outer again around a lower sleeve, has between two lower sleeves at interval and the lead to the hole site of two lower sleeves is staggered.This is the two-level sleeve modulating valve, owing to increased one deck sleeve, and the lead to the hole site of two sleeves is interleaved, like this, medium is had certain inhibition, can adapt to 30-60Kgf/cm
2The operating mode occasion.Based on same reason, sleeve adjusting valve can also be made three grades, level Four, in addition more senior.As shown in Figure 5 and Figure 6, this is three grades of sleeve adjusting valves, can adapt to 60Kgf/cm
2Above operating mode occasion.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop on claim scope of the present utility model to the above embodiment's variation, modification.
