Description
Technical field
This utility model relates to flow control valve technical field, especially relates to a kind of convergence and dissipates spout regulation valve.
Background technology
It is known that flow control valve is also known as flow control valve, flow controller, dynamic balance valve, flow balance valve, it is
One realizes flow rate adjusting control valve door gear.
In general, for regulation valve, its regulatory function is the most mostly important；General flow control valve design
Technology requires: performance is good, it is special to meet required flow to require stable action when regulation valve works, opening ratio to regulate time less
Property, the technical characterstic such as flow resistance is little, flow-rate ratio is big, governing speed is fast.
In a particular application, when fluid media (medium) flows through pipe-line system, owing to can produce along journey friction and valve local resistance
Circulating resistance, these circulating resistances can cause the energy loss of system.Meanwhile, the circulation of flow control valve (abbreviation valve)
Resistance will be negatively affected to systematic function.Therefore, the selection of the structure of regulation valve, it is impossible to only consider that valve plays regulation
Effect, it is necessary to the local resistance making valve is the least (i.e. requiring that the local resistance of regulation valve is little).
It will be apparent that the circulating resistance coefficient of valve depends on the size of valve products, structure and cavity shape；Valve body cavity
In each element can be seen as being an element system producing resistance (fluid turns, expands, reduces, again turning etc.).
So the pressure loss in valve approximates the summation of each element pressure of valve loss.
Wherein, fluid is turned, and fluid section speed consumes and forming the aspects such as eddy current, the agitation of fluid and heating；Especially
Being that knuckle is turned, produce turn sharp, coefficient of partial resistance is big.Almost all of regulation valve all can produce fluid and turn, fluid
Turning can cause valve regulated unstable, increase circulating resistance.
Therefore, how to design a Novel flow control valve not having fluid to turn, be the crucial skill of ability technical field
Art.
