Preferably, be provided with wear-resistant seal face on described sphere, wear-resistant seal face is hard alloy surface.
The utility model compared to existing technology outstanding and useful technique effect is:
Of the present utility model simple in structure, safe and reliable, can be suitable for the various industries of various operating modes; Installation accurate positioning between upper valve rod and valve body, is easy to revolution; Good seal between spheroid and soft or hard Double-seal valve seat;
The pressure loss of the present utility model is little: during standard-sized sheet, damage by water is zero, and runner is completely unimpeded; Inner chamber cleans automatically, spool 90 degree rotations, and auto-flushing body cavity, cleans up the foreign material in medium and medium can not be deposited in valve pocket.Spheroid is hemisphere, and circulation has the highest Cv value, has strengthened the system effectiveness of pump, and makes abrasion reduce to minimum level;
The resistance to abrasion of particles of the utility model: utilize two eccentric principles in closing process, only spheroid just relies on valve seat at the last moment, and does not form friction; And the seal ring build-up wear-resistant self-lubrication alloy on valve seat, not easy to wear, be difficult for being washed; Between the spheroid of knife-edge ball mouth and valve seat, there is wiping cleaning and shear action less scaling;
The utility model automatic compensation sealing is reliable: during malleation, utilize eccentric principle, spheroid and soft or hard Double-seal valve seat close tighter and tighter, thereby obtain good sealing; During back-pressure, floating type soft or hard Double-seal valve seat is when pressurized, and soft or hard Double-seal valve seat is from the push-tight of trend spheroid, and the higher soft or hard Double-seal valve seat of pressure pushes away tighter and tighter to spheroid, thereby obtains good sealing; Lasting tightening seal can be kept, harsh operating mode can be adapted to.Under long-term use, soft or hard Double-seal valve seat sealing is if any wearing and tearing or damage, under spring action soft or hard Double-seal valve seat from the push-tight of trend spheroid, thereby obtain good automatic compensation function;
The utility model is applicable to high flow rate medium: a side that is hidden in valve pocket because of spheroid forms straight-through runner without flow resistance, firm eccentric fixed crankshaft, friction, noise free in the medium of high flow rate;
The utility model life-span, long switch was light: without easily worn part, due to eccentric effect, in valve opening and closing process, the sealing surface of spheroid and valve seat departs from completely, makes without scratch, to do without frictional rotation between valve base surface and spherical crown sphere, effectively reduced operational torque and turned round, operation is light and handy; The automatic compensation function of valve, the life-span of having improved greatly valve;
The utility model is easy to maintenance: the design of this valve reassembling type, and spheroid and valve seat pack into from valve side; During maintenance, only need take pressing plate taking-up valve seat apart and can carry out maintenance and seal ring and other accessories.
