Description

A kind of grid type flow valve
Technical field
The present invention relates to flow valve field, and in particular to a kind of grid type flow valve.
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.
The content of the invention
In order to overcome above mentioned problem, the present invention proposes solve the valve of above-mentioned seven kinds of problems simultaneously.Solved by a kind of structure Seven kinds of problems.
The technical solution adopted for the present invention to solve the technical problems is：A kind of grid type flow valve, including right valve barrel, in Valve body, left valve barrel, bicyclic cylinder, chute, fixing bolt, handwheel, temperature sensor, driving caliper scale, flowmeter, valve rod, valve plate, grid Cell, hollow block, position limiting structure, keep out of the way groove, outer cover, chamber, locking groove；On outer cover, it is provided with the plane vertical with hand wheel pole Keep out of the way groove, the middle valve body top is T-shaped, and valve rod is oriented to through middle valve body top and by middle valve body；Grid type is formed in valve to drive Dynamic model block, side driving structure, microgap adjusting module, valve opening feedback mechanism, sensing module；Grid type drive module structure It is as follows：Handwheel connect hand wheel pole, hand wheel pole connection driving caliper scale, driving caliper scale it is first-class set up separately put at 1 points, wherein three Point sets hollow block, and a point sets position limiting structure；Be arranged in parallel at least three grid grooves on valve rod, and three grid grooves prolong valve rod Axis direction is sequentially arranged, circumferential along valve rod, the starting point of next grid groove, and the terminal with top grid groove is positioned at same successively One vertical curve, the bottom setting locking groove of all grid grooves, the shape adaptation of locking groove and the position limiting structure, confession are spacing Structure is embedded or leaves；Side driving structure sets as follows：Hand wheel pole is arranged on the left side of outer cover, horizontally extending, handwheel Hand wheel pole left end is connected to, driving caliper scale is connected to hand wheel pole right-hand member, and driving caliper scale diameter parallel is driven in horizontal plane, driving caliper scale Ovable valve stem moves, the motion of valve rod drive valve plate；Microgap adjusting module structure is as follows：It is left valve barrel side in downstream, sets single Side microgap adjusting module, the contracting of left valve barrel left end footpath, the bicyclic cylinder of footpath contracting part peripheral hardware, bicyclic cylinder upper end sets the chute, sliding Fixing bolt is set on groove, and bicyclic cylinder is fixed on footpath contracting part by fixing bolt；Valve opening feedback mechanism includes driving caliper scale On hollow block, hollow block and grid groove contact-impact send the sound, and user can judge that valve is opened according to the sound and tactile Degree；Sensing module includes temperature sensor and flowmeter, and outer cover surrounds the chamber with middle valve body upper end, and temperature sensor is arranged on One of inferior horn of the chamber, flowmeter are arranged on another inferior horn of the chamber, and temperature sensor and flowmeter pass through Middle valve body upper wall stretches into fluid flowing path, and the outer cover uses transparent material.
Preferably, deep among the grid groove, both ends are shallow.
Preferably, the shallow end bearing of trend of the grid groove is adapted to hollow block trend.
Preferably, the hollow number of blocks is 4.
Preferably, 4 hollow blocks and 1 position limiting structure will drive circumferential 5 deciles of caliper scale.
Preferably, the position limiting structure is hook-type.
Preferably, the bottom of the middle valve body has depression to be embedded in for valve plate.
