Description

A kind of big runner labyrinth type sleeve
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.
Utility model content
In order to solve the problems referred to above, the big runner labyrinth type sleeve that this utility model provides
Have employed following technical scheme:
A kind of big runner labyrinth type sleeve, including base plate, the first chip, the second chip, the 3rd chip, top board, its feature It is: alignment pin is installed on described base plate, is then repeated in superposition the first chip, the second chip, the 3rd chip, bonnet It is screwed after upper plate, the first described chip is uniformly provided with multiple strip runner being opened to inner side, described second Chip is provided with the short runner corresponding with the first chip, its opening outside the second chip, short runner and the first chip strip stream Road communicates, and the 3rd described chip has hole, location and fixing hole;Described the first chip, the second chip, the 3rd chip composition The labyrinth path of one shape the most horizontal.
Preferably, the ring footpath of the first described chip is less than the ring footpath of the second chip, the ring footpath of the second chip and the 3rd core The ring footpath of sheet is equal.
Preferably, the inner side of described labyrinth path is provided with balancing slit.
Preferably, described the first chip, the second chip, the 3rd chip is minimum is two groups.
Preferably, described labyrinth path the most progressively expansionary channel.
The beneficial effects of the utility model are: provide a kind of simple in construction, big runner labyrinth type set convenient for production Tin, it provides the labyrinth path of the most horizontal a kind of shape, multilevel decompression, and entrance channel is 4mmx5.21mm, the most progressively Expansionary channel, is fully able to ensure that the grains of sand of below 3mm pass through, and FTC flows to large granular impurity to be got lodged in entrance at stream Containing under the operating mode of granule foreign in body, fluid can pass through completely smoothly, and antihypertensive effect is good.
