Description
Technical field
This utility model relates to the spare and accessory parts of valve, relates to a kind of big runner labyrinth type sleeve.
Background technology
Along with rapid industrial development, in special High Pressure Difference technological process, the valve for using in technique proposes makes an uproar
Sound is low, regulation is stable, reduce cavitation, reduce the requirements such as vibration, easy-maintaining, length in service life.Common valve mechanism cannot
Meet technological requirement set forth above.Some imported valves use the mode of labyrinth throttling channel blood pressure lowering preferably to meet these works
Skill requirement, it is achieved that anti-cavitation, anti-flash distillation, low noise, the design of low vibration, is widely used in the high pressure drop such as thermoelectricity, chemical industry
Liquid, steam and gas emptying occasion.But weak point is that the tube-in-tube structure of this structure is extremely complex, the cross section of sleeve window
Long-pending the least, easily blocked by rubbish, cause valve jam and cannot action, be not suitable for the medium operating mode containing particulate matter, then
Person labyrinth throttling channel processing technique is more complicated, and the chip soldering that multiple spark machined is usually taken forms, complex process, processing
Relatively costly；High Pressure Difference in the industries such as oil refining the medium containing particulate matter, generally use multisection type spool knot both at home and abroad
The valve of structure, the valve of this kind of structure can effectively prevent particulate matter from blocking the valve jam caused, it is also possible to a certain degree
On realize blood pressure lowering, but owing to its structure limits, the antihypertensive effect of multisection type spool can not show a candle to labyrinth type sleeve.
Therefore design a kind of novel anti-cavitation, anti-vibration, blood pressure lowering and to may be used for the valve containing particulate matter operating mode the most urgent
At the eyebrows and eyelashes.
