Description
Technical field
The present invention relates to valve technology fields, more particularly to a kind of ceramic guiding valve.
Background technology
In the industries such as coal chemical industry, silication work, mine metallurgy, power environment protection, there are a large amount of conveying gas solid, liquid to consolidate, gas-liquid-solid
The medium of three-phase, especially in grit mixture condition, it is used at present be mostly hard seal ball valve, butterfly valve, sluice valve, gate valve, insert
The valves such as plate valve more or less have service life not grow, problem difficult in maintenance, and the especially strong operating mode of part erosion is to close
Envelope requires stringent, but there are media sticky, easy caking, easy fouling, easily crystallization or the occasion containing bulky grain, not only washes away sternly
Weight, also often results in the case where various valve blockages are blocked.
By taking most commonly used hard seal ball valve under these current operating modes as an example, it is analyzed as follows：
(1) for ball valve in opening-closing process, medium easily enters valve chamber, and is accumulated in valve chamber；The meeting when medium temperature reduces
It causes certain media to solidify and locking opening and closing element, therefore easily leads to the serious consequences such as valve is stuck.
(2) and when the granule medium in-line flow at high speed of high rigidity, sealing surface of seat damage or sphere are easily led to
Surface spraying layer falls off, and then influences valve seal effect, when serious, valve seal can be caused to fail.
Sluice valve valve since lumen is full of material, and leads to valve blocking after running a period of time；Slide plate and clamping plate
Between serious wear, while in above system, due to the physicochemical characteristics of fluid, some valves often occur trim or
The damage that runner is seriously washed and cavitates after valve seat in turn results in what the even entire transport system of valve cannot all run well
Failure.
Butterfly valve, gate valve, gate valve etc., due also to the bias current of medium fluid is serious, are very easy in addition to sealing performance is bad
Runner is washed away, pipeline is caused to need to be replaced frequently.
Regulating valve can be done therefore, it is necessary to one kind and makees switch valve, and lumen no backup, unsuitable blocking, medium do not wash away
The valve of sealing surface, to ensure the long-term operation of system.
Invention content
The object of the present invention is to provide a kind of ceramic guiding valve, realize that various slurries, gas-solid granule medium, gas-solid-liquid three-phase are situated between
Not interim card, the blocking of valve in matter, sealing is permanently effective, improves valve service life.
To achieve the goals above, technical solution of the invention is：Medium is artificial by valve flowing channel hole and pipe hole
It separates, when reducing valve opening and closing, medium washes away sealing pair；By the sliding block with valve flowing channel hole respective shapes, by stream

State；Valve seal performance is improved in this way, and increases the service life of valve, and the fire prevention demand of valve can be met.
Compared with the existing technology, protrusion effect of the invention is：
(1) the configuration of the present invention is simple, compact, keying torque is small, is not easy blocking, avoids bias current, and have self-cleaning function,
Both regulating valve can be used as to use, and can also be used as switch valve use, is a kind of very strong valve of versatility, it is miscellaneous to be particularly suitable for medium
Matter is more, easy fouling, crystallization, occasion sticky or containing bulky grain, can effectively avoid various blockings, and primary seal pair uses high-performance
Structural ceramic material has fabulous corrosion resistant, wear-resisting, flushing resistance, substantially increases the service life of valve.
(2) common hard seal ball valve sealing pair is spherical structure, and such sealing pair is to process equipment and the accuracy of manufacture
It is required that high, sealing surface of seat is ground after must being finished with sphere, and match grinding is also needed to after grinding, and production technology is complicated,
Production cycle is long, therefore its production efficiency is low, and production cost is constantly soaring.The sealing pair of the present invention uses flat seal knot
Structure ensure that good sealing performance, and improve processing technology.Therefore, no matter from properties of product, manufacturing cost and life
The angle of production efficiency is set out, and the present invention has a clear superiority.
(3) use integral sintered hard alloy or ceramic material as critical piece, it can be to avoid solid under High Pressure Difference
Grain is washed away and is cavitated to trim and runner, to reduce the destruction to them.
(4) again by the shape for designing various throttle orifices, this valve is made not only to have break-in facility, and can be according to customer requirement
Realize the adjusting of various discharge characteristics.
(5) present invention have good seal performance, the long-life, easily manufacture, just safeguard and good appearance, compact-sized etc. it is excellent
Point.
