The beneficial effects of the utility model are: a kind of balanced manual flow control valve structure, including regulation valve body, regulation core and operating portion, operating portion is connected with regulation core, and operating portion is threadeded with regulation valve body, being provided with counter balance pocket in regulation valve body, regulation core is provided with balancing segment；Described balancing segment is arranged in counter balance pocket, makes counter balance pocket be divided into power-assisted chamber and the pressure-releasing chamber of variable volume；Regulation core is provided with the regulation section for regulating flow, regulation core such as is provided with at the pressure pipeline, it is located in described regulation section Deng an opening of pressure pipeline, it is located at power-assisted intracavity Deng another opening of pressure pipeline, it is additionally provided with pressure release passage in regulation valve body, pressure release passage connects with described pressure-releasing chamber, and regulation section and pressure-releasing chamber are each provided at the left side of balancing segment, and power-assisted chamber is located at the right side of balancing segment.Power-assisted intracavity can be made equal with the hydraulic pressure that regulation section is subject to Deng pressure pipeline, therefore regulation section partly or entirely can be offset with balancing segment hydraulic pressure to the left by hydraulic pressure to the right, to reduce the operation pressure of operating portion so that this utility model operating physical force is little, reliability is high.This utility model is for the Flow-rate adjustment of hydraulic system.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model rather than whole embodiment, and those skilled in the art is not on the premise of paying creative work, it is also possible to obtain other designs and accompanying drawing according to these accompanying drawings.
Fig. 1 is the cross-sectional schematic during use of this utility model embodiment.
Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is clearly and completely described, to be completely understood by the purpose of this utility model, feature and effect.Obviously; described embodiment is a part of embodiment of the present utility model rather than whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art is obtained on the premise of not paying creative work, belong to the scope of this utility model protection.It addition, all connection/annexations being previously mentioned in literary composition, the most singly refer to that component directly connects, and refer to couple auxiliary according to being embodied as situation by adding or reducing, form more excellent draw bail.Each technical characteristic in this utility model, can be with combination of interactions on the premise of the most conflicting conflict.
With reference to Fig. 1, this is an embodiment of the present utility model, specifically:
A kind of balanced manual flow control valve structure, including regulation valve body, from right and the regulation core 2 of left extension and operating portion 3, operating portion 3 is connected with regulation core 2, operating portion 3 with regulate valve body and threaded, being provided with counter balance pocket in regulation valve body, regulation core 2 is provided with balancing segment；Described balancing segment is arranged in counter balance pocket, makes counter balance pocket be divided into power-assisted chamber 41 and the pressure-releasing chamber 42 of variable volume；Regulation core 2 is provided with the regulation section for regulating flow, the pressure pipeline 21 such as grade with two openings it is provided with in regulation core 2, it is located in described regulation section Deng an opening of pressure pipeline 21, it is located in power-assisted chamber 41 Deng another opening of pressure pipeline 21, being additionally provided with pressure release passage 22 in regulation valve body, pressure release passage connects with described pressure-releasing chamber 42, and regulation section and pressure-releasing chamber 42 are each provided at the left side of balancing segment, power-assisted chamber 41 is located at the right side of balancing segment so that this utility model structure is the most simple and reliable.Due to equal with the hydraulic pressure that regulation section is subject in waiting pressure pipeline 21 can make power-assisted chamber 41, therefore regulation section partly or entirely can be offset with balancing segment hydraulic pressure to the left by hydraulic pressure to the right, to reduce the operation pressure of operating portion, therefore this utility model operating physical force is little, reliability is high.
In some cases, operating portion needs certain coupling mechanism force, to prevent maloperation；And in yet some other cases, need flow is adjusted accurately, it is desirable to operating physical force is the lowest more good；Also has certain situation, it is desirable in the hydraulic system that the hydraulic pressure amplitude of variation of hydraulic system is bigger, it is desirable to operating physical force is not changed by the change of hydraulic pressure.Therefore allowing power-assisted chamber 41 is being between 0.5 ~ 2 in area and the regulation section of edge regulation core 2 bearing of trend projection along the ratio of the area regulating the projection of core 2 bearing of trend, when above-mentioned ratio is 1, operating physical force is minimum not to be affected by the size of the hydraulic pressure of system.
When regulating the machining accuracy of correspondence position of core 2 and regulation valve body and being sufficiently high, regulation core 2 and regulation valve body just can realize without sealing member sealing, but in order to reduce processing cost, difficulty, regulation core 2 is provided with the regulation valve body sealing member for sealing with regulation valve body.
In like manner, balancing segment is provided with the balanced seal part 24 for sealing with counter balance pocket.
Assembling for convenience and process, regulation valve body includes regulation parts 11 and the interior threaded part 12 linked together, and described counter balance pocket is located in regulation parts 11, and described operating portion 3 is threadeded with interior threaded part 12.
Above better embodiment of the present utility model is illustrated, but this utility model is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement on the premise of this utility model spirit, and modification or the replacement of these equivalents are all contained in the application claim limited range.
