Advantage of the present utility model and beneficial effect:
The utility model can make valve density rating height can reach modulating valve and leak standard, inner piece adopts special tungsten carbide material mostly, the antiscour of valve, corrosion-resistant, heat-resisting quantity have been improved greatly, and the valve advantage of having assembled ball valve and adjusting, make valve Applicable media wide (as long as rational selection can be fit to most media), eliminate the stuck and switch phenomenon not in place of valve simultaneously, long service life can reach more than 20 ten thousand times.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model comprises valve body and spool, wherein:
Valve body is made as upper valve body 14 and following valve body 1, the ball-type spool 20 of single channel stationary structure is set in the cavity of upper and lower valve body 14,1, have a V-type Flow-rate adjustment mouth on the spool 20, spool 20 outsides are close to and are provided with seal valve seat, spool 20 also connects the opening-closing shaft of controlling its keying, and opening-closing shaft passes valve body and is arranged on spool 20 both sides;
Described seal valve seat comprises the valve seat 4 that is located between spool 20 runner mouths and the valve interior wall, the valve seat graphite circle 21, valve base sealing ring 22, pad 23 and the valve seat that are fixed on the valve seat 4 by valve seat pressure cap 7 overlap 24, and are located at graphite annulus 5 and planar spring 6 between valve seat 4 and the following valve body 1;
Described opening-closing shaft comprises rotating shaft 11 and the back shaft 16 that is arranged on spool 20 both sides, and rotating shaft 11 pivot movable valve plugs 20 rotary opening and closing valves;
All be inlaid with the Tungsten carbite cover in the runner mouth of described valve seat 4, upper valve body 14 and following valve body 1, spool 20 and following valve body 1 inner chamber all are coated with Tungsten carbite.
Rotating shaft 11 described in the utility model is arranged between spool 20 1 sides, upper valve body 14 and the following valve body 1 by gland 12, and connects with bolt; Also be provided with axle sleeve 8, rotating shaft cushion block 9 and carbon seal ring 10 between rotating shaft 11 and the upper and lower valve body 14,1.Described back shaft 16 is arranged on the opposite side of spool 20, and fuses with upper and lower valve body 14,1, and also be provided with cover plate graphite circle 17 between cover plate 19 and the upper and lower valve body 14,1 by cover plate 19, sealing gasket 18.Described upper valve body 14 and following valve body 1 inwall all are provided with lining 3, also are provided with pressing plate 2 between lining 3 outer ends and the valve body.
Working principle of the present utility model:
Hard seal combination seal valve seat of the present utility model is under the effect of medium, make hard seal valve seat be close on the spool and the automatic capturing centre of sphere, this moment, hard seal valve seat was subjected to the effect of two power: the annulus area of the hard seal valve seat of pressure * of the pressure F=medium of 1 medium.The pretightening force Q(of 2 elastic sealing strips is fixed by design).These two power are formed sealing force (surface friction drag of having ignored some Sealings) valve seat and the valve seat cover that seal between hard seal valve seat and the spool and are guaranteed sealing by graphite pads.Stack valve seat realizes under the effect of the pressure of medium and elastic sealing strip pretightening force and the sealing of spool when valve closing.The high temperature slurry oil is high temperature and has the dregs of fat, common hard black box is difficult to reach requirement, for guaranteeing the leakage rate of valve, guarantee that the spool valve seat is not washed away, therefore inlayed special cemented carbide at upper valve body and following valve flowing channel mouth inboard, sprayed one deck Tungsten carbite at spool and valve insertion surface.
