Abstract
The utility model discloses a maximum flow value adjustment structure for a dynamic-balance electric adjustment valve. According to the maximum flow value adjustment structure, a valve rod is installed on a valve core by a press column and an adjustment top cover, an elastic stop ring and an open stop ring are installed on the upper portion in a valve cover, a spring is installed outside the valve core in a sleeving manner, a lower sealing ring is padded on the valve cover at the lower portion of the spring, and a sealing pad and an upper sealing ring are installed between the adjustment top cover and the valve cover; flow scale lines are formed on the valve rod; the valve rod is in threaded connection with the valve core; flow scale lines are arranged on the valve rod, and the valve rod is in threaded connection with the valve core. According to the maximum flow value adjustment structure disclosed by the utility model, an adjustment on the maximum flow of the valve is realized by adjusting the position of the valve core by controlling the position of the valve rod, adjusting the top cover and the valve cover, and adjusting the maximum stroke of the valve core by a thread. The maximum flow value adjustment structure has the advantages of being simple in structure, easy to machine, convenient to use, low in cost and high in efficiency, and is suitable for being applied as a dynamic-balance electric adjustment valve structure capable of adjusting the maximum flow.
Description
Technical field
The utility model is the optimization to valve peak rate of flow regulation structure, specifically dynamic balance electric regulating valve peak flow values regulation structure.
Background technique
Valve, in many applications, due to on-the-spot demand, needs constantly to change its peak rate of flow, and same valve is in different occasions, and the peak rate of flow needing is also to distinguish to some extent.The method in the past addressing this is that is exactly that this method has increased the kind of valve, has increased manufacture cost according to the valve of different customization different flows, also easily obscures, and can not meet the occasion that becomes peak rate of flow.The structure of current existing regulating valve peak rate of flow is too complicated, and difficulty of processing is high, is not easy to dismounting, maintenance.
Model utility content
In order to overcome the defect of existing dynamic electronic flow adjusting structure, the utility model proposes dynamic balance electric regulating valve peak flow values regulation structure.This structure is passed through the stroke with threaded adjusting spool, thereby plays the effect of regulating valve peak rate of flow.Solve the technical problem that dynamic balance electric regulating valve peak rate of flow regulates.
The scheme that the utility model technical solution problem adopts:
Valve rod is arranged on spool by compression leg, adjustment top cover, valve gap internal upper part is equipped with circlip and split washer, in spool outer cover, spring is housed, on the valve gap of spring bottom, is lined with lower seal, adjust between top cover and valve gap sealing gasket and upper seal ring are housed.On valve gap, be carved with flow scale line.
On valve gap, be carved with flow scale line.
Between top cover and valve gap, be provided with screw thread.
Good effect, the utility model is adjusted the position of spool by controlling the position of valve rod, adjust top cover and valve gap, carrys out the range of regulating spool, thereby realize the adjusting of valve peak rate of flow by screw thread.Have advantages of simple in structure, be easy to processing, easy to use, cost is low, efficiency is high.Suitable conduct can regulate the dynamic balance electric regulating valve structure applications of peak rate of flow.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation
In figure, 1. valve rod, 2. compression leg, 3. adjusts top cover, 4. circlip, 5. split washer, 6. spring, 7. spool, 8. lower seal, 9. sealing gasket, 10. goes up seal ring, 11. valve gaps.
Embodiment
According to the figure, valve rod 1 is arranged on spool 7 by compression leg 2, adjustment top cover 3, valve gap 11 internal upper parts are equipped with circlip 4 and split washer 5, in spool outer cover, spring 6 is housed, on the valve gap of spring bottom, be lined with lower seal 8, adjust between top cover and valve gap sealing gasket 9 and upper seal ring 10 are housed.
On valve gap, be carved with flow scale line.
Between top cover and valve gap, be provided with screw thread.
Working principle of the present utility model:
Valve gap is assemblied on valve body, spool is through valve gap, adjusting top cover is connected with valve rod, and by spring reset capable become an entirety, by controlling the position of valve rod, adjust the position of spool, adjust top cover and valve gap carry out regulating spool range by screw thread, thereby realize the adjusting of valve peak rate of flow, circlip on valve gap plays the effect of controlling spool range, the seal ring of adjusting on spool plays certain self-locking action, prevent that valve from changing because vibrations produce voluntarily, this is a kind of the most simple and practical self-locking structure, remaining seal ring all plays the effect of sealing, by rotation, adjusting top cover like this can regulate the peak rate of flow of valve, and there is the scale of pair use to show, dial is housed on valve gap, adjust on top cover and have indicating arrow, structure not only simply but also practical, well solved traditional complicated structure, difficulty of processing and assembling difficulty have been reduced, and also for ease of maintenaince.
Feature:
The utility model structural design is more simple compact, be mainly to realize on the basis of valve switch function, increase the regulation structure of a valve stroke, the range of regulating valve, adjustment stroke scope is spacing by circlip, thereby realizes the peak rate of flow of regulating valve.Simple and practical, only need hexagon can realize adjusting, and have corresponding scale to show, can accurately adjust the size of flow.
1, simple in structure, be easy to processing:
Due to the regulation structure of the utility model employing screw thread, both simple and practical, be convenient to again processing and assembling, saved process time, reduced the quantity of part.
2, easy to use, cost is low, efficiency is high:
Due to of the present utility model simple in structure, manufacture assembly cost low, fairly simple in production assembly process, there is no buckle structure, adopt screw thread and circlip Placement, therefore easy installation and removal, is convenient to manufacture produce and keeps in repair.
3, adjust flux scale shows:
The utility model band flow scale Presentation Function, this model utility not only can adjust flux, can also know exactly the size of institute's adjust flux, very clear, can save the time of debugging.
