Using eccentric valve body, eccentric spheroid and ceramic core, ceramic valve seat, in common locus when valve rod rotates eccentric half-ball valve
Self-centering, valve closes tighter and tighter, is fully achieved good sealing purpose.After unlatching, the ceramic core of valve and ceramic valve seat
Completely disengage from, eliminate the abrasion of sealing pair, overcome what conventional ball valve valve seat and spheroid contacted all the time, eliminate sealing pair
Abrasion.The research and development success of double eccentric ceramic half ball valves, is chemical industry, oil, combustion gas, metallurgical, the industrial department solution process such as electronics
It is easy precipitation in flow process, fouling, separate out and affect to provide reliable control valve, for improving China's industry in the predicament of flow process
Management equipment provides new excellent product.
Utility model content
The purpose of this utility model is to improve the deficiency of prior art, provides a kind of pair of eccentric ceramic half ball valve, its gold
Belong to valve body and metal ball body using eccentric design, in common locus self-centering when valve rod rotates, valve closes tighter and tighter,
It is fully achieved good sealing purpose.Sealing pair adopts ceramic material simultaneously.Double eccentric structures ceramic core when opening is located at
Hide ball indoor, flow area is big, and valve is not washed, during closing, ceramic core is not washed, and during unlatching, valve element sphere is along valve
Seat is progressive, effectively excises fouling obstacle, realizes reliably sealing.So that ceramic half-ball valve is used safer, improve making of valve
Use the life-span.
For realizing this utility model purpose, there is provided technical scheme below: a kind of pair of eccentric ceramic half ball valve, its feature exists
In including metal valve body, corresponding valve rod port and the short axle port being opened in metal valve body upper and lower side, short axle port is provided with end
Lid, is provided with lower short axle, is provided with valve rod in valve rod port, be provided with eccentric sphere crown type Ceramic Balls in valve body in short axle port
Core, eccentric sphere crown type Ceramic Balls core includes ball crown type metal ball-collecting rack and the arc pottery being installed on ball crown type metal ball-collecting rack arc tips
Porcelain block, the ball crown type metal ball-collecting rack other end offers inc runner, and ball crown type metal ball-collecting rack upper end connects valve rod bottom, under
End connects lower short axle upper end, and metal valve body right-hand member is provided with ceramic valve seat retainer ring, ceramic valve seat retainer ring is provided with pottery
Valve seat, ceramic valve seat inner surface curved surface is cooperated with arced ceramic block surface curve.
Preferably, valve rod port opens up relative to valve body bias with short axle port.
Preferably, the arced ceramic block of eccentric sphere crown type Ceramic Balls core is with respect to valve rod eccentric setting.
Preferably, ceramic valve seat is fixed in ceramic valve seat retainer ring, there is coating material between the two.
Preferably, end cap is provided with Graphite pad with the joint face of short axle port.
Preferably, ceramic valve seat retainer ring is provided with Graphite pad with the joint face of valve body right-hand member.
Preferably, lower short axle is provided with graphite bed course with the horizontal contact face of short axle port.
In order to realize the purpose of this utility model further, its sealing pair is made up of ceramic material, i.e. arced ceramic
Block and ceramic valve seat, arced ceramic block and ceramic valve seat seal more reliable after abrasive polishing process processing.
This utility model beneficial effect: general structure design is short and sweet, its be first metal valve body and metal ball body all
Employ eccentric structure design, using eccentric valve body, eccentric spheroid and ceramic core, ceramic valve seat, when valve rod rotates
In common locus self-centering, valve closes tighter and tighter, is fully achieved good sealing purpose.This utility model simultaneously, its valve
Sealing pair adopt ceramic material, because ceramic material also has self-lubricating property, coefficient of friction is little, and valve opening and closing moment of torsion is little.
The ceramic half-ball valve of double eccentric structures ceramic core when opening is located at hides ball interior, and the flow area of valve is big, and valve is not
It is washed, during closing, ceramic core is not washed, and during unlatching, valve element sphere is progressive along valve seat, effectively excises fouling obstacle, real
Now reliably seal.Ceramic valve seat is fixed in ceramic valve seat retainer ring, has coating material between the two, facilitates implementation the fast of valve
