The inner flow passage of described valve body cavity of resorption is streamlined, and the madial wall of cavity of resorption is provided with flap.Prevent fluid vortex, avoided the rotation of spool, reduced flowing medium washing away the valve body inner flow passage.
The internal diameter of described guide sleeve is provided with a plurality of grooves.Described groove is rectangular recess or arc groove.
Described spool is the once sintered moulding of superhard extraordinary diamondite, and cylindrical is provided with helical groove, and perhaps cylindrical is provided with the involute groove.
The one group through hole of flowing medium on the valve body isolation surface flows into, and from the groove outflow of guide sleeve, finished the whole circulation cleaning of valve body, prevents that the particle fouling is in groove; Simultaneously, helical groove on the spool cooperates the straight groove of guide sleeve, and ' the scraper effect ' when having realized spool and guide sleeve relative movement stopped particle and be stuck in both matching gaps; Prevent that again high pressure is pressed into stuffing box with particle, cause the valve rod scratch, valve leaks.
Described valve seat is divided into valve seat section and valve seat diffuser, and valve seat section and valve seat diffuser are spirally connected and are fixedly clamped.The internal diameter of described valve seat diffuser is horn-like to external diffusion.It is split type that valve seat adopts, and on-the-spot only the need both can conveniently be taken out the dismounting of adapter flange bolts at two ends valve seat, changes or safeguard that spool also can on-line maintenance simultaneously.
Superior effect of the present utility model is:
1) the utility model is applied to KAS venturi Heisui River modulating valve, can realize pressure balance, functions such as circulation cleaning, scraper effect voluntarily, avoids spool, guide sleeve stuck;
2) solve frequent guide sleeve and the stuck problem of spool of taking place in the particle media, improved the stability of spool, prolonged working life;
3) reduce the epicoele amounts of particles, reduce upper cavity pressure, avoid the high pressure granule medium to be pressed into stuffing box, cause the valve rod scratch, valve leaks;
4) prevent flowing medium eddy current in cavity, cause the spool rotation, performance is out of control;
5) its hardness of the spool of superhard extraordinary Tungsten carbite sintering reaches HRA 〉=89, and superior antiscour, anti-corrosion capacity are arranged;
6) the straight groove of cylindrical helical groove and guide sleeve is effectively realized the scraper effect, and the straight groove of spool helical groove and valve body equalizing orifice and guide sleeve forms the flow circulation, finishes the automatically cleaning of valve body, need not the outside energy, and is simple and convenient;
7) the valve seat employing is split type, has realized online dismounting, maintenance, replacing, has improved the economic performance and the usability of valve, has improved efficient.
