Description
Technical field
The present invention relates to flow valve field, and in particular to a kind of method for dismounting of the adjustable double valve plates valve in gap.
Background technology
First, existing flow valve, for many years after use, it may appear that when needing the operating mode changed, but changing, because the years become
Move, can not find the valve of identical specification；Note：Caliber size can be standard, but because valve is the parts of non-normal open, it is raw
It is more to produce producer, although defining dimensional standard, this standard is only for external dimensions, when reality connects, due to internal thread, pad
The manufacture of each producer of the structures such as piece will not be identical, so using when inevitably occur that pipeline connects error, it is this
Error is probably 0.5mm, but for fluid conveying, 0.5mm causes serious leak enough.
The more seriously presence of negative clearance, it can not be properly settled after there is the problem.
2nd, in addition, existing flow valve, it is difficult there is also connection even if size is corresponding when being changed after long-term use,
Because what the size reserved in pipeline to valve was to determine, the valve of identical size is if it is desired to connecting among two pipelines
Size, it is necessary to which hard card gets on, or gets on by instrument hard card, because the size among two pipelines corresponds to the size of valve, no
Installing space can be reserved.Can be connected in advance during initial installation, when maintenance is changed can only hard card get on.At this moment, often easily
Pipe joint is caused to damage, causes damage to change a valve to valve interface, and causes damage to want to change pipeline to pipe joint
Serious inconvenience can be caused to production and living.
For above-mentioned two problems, existing solution is that microgap uses pad mostly, but in high pressure industrial pipeline
Pad cannot guarantee that high-seal.For negative clearance, not no good solution.
Valve union/pipe joint or pipe flange are not known where to begin more, because not similar to 0.5mm size, even if there is this
The joint or flange of kind size, there is also connection adaptation issues.Specifically, outer-enwraped type pipe joint is inevitably absolute in other words
The problem of size can not be adapted to 0.5mm be present, same internal connecting type pipe joint can not be also adapted to.
3rd, existing flow valve, because most of pipeline is arranged on, design is either buried in corner or pipeline is complicated, is changed
It occur frequently that interfering with each other during valve, the drive part of especially valve is high high to be stretched out, when rotation is changed often with receiving space
Or other pipelines interfere.
4th, existing flow valve, carry out precision control valve door aperture using graduated scale sometimes, or even can be controlled using sensor
Valve opening processed.But add use cost.And the working environment of valve, if corner or burial, insufficient light can not
See graduated scale clearly.
5th, existing poppet, small part special requirement can be driven using worm and gear, but often be arranged in pairs or groups with multiple parts
Form drive mechanism, structure is complex, and only worm gear structure it is simple after, transmission agency is but can be only done, it is difficult to real
Existing support function.
And existing electromagnetic drive, it is possible to achieve valve rod and drive part are from but being difficult to the lifting of big weight valve element.
Certainly, reduction box, change gear train etc. can play good result, but it is complicated, cost is high.
It can be seen that a kind of both flexible driving is difficult to find that in prior art, but good supporting force, key are the low driving sides of cost
Formula.
6th, existing flow valve, when maintenance and cleaning needs to take apart, generally require directly to remove valve rod, but this is often
Upper valve body, valve seat, valve rod, valve element etc. is needed all to remove.
7th, prior art flow valve, flowmeter are generally located on valve body-side, and small part is designed in valve body lower portion, and cruelly
It is exposed at outside valve, precision instrument is fragile.
8th, existing poppet, after valve plate prolonged exercise, easily worn between valve body.
The content of the invention
In order to overcome above mentioned problem, the present invention proposes solve the valve of above-mentioned eight kinds of problems simultaneously.Solve eight kinds by a kind of structure
Problem.
