You question is a bit unclear.
Here I assume v is velocity, t is time, and f is Force.
dv/dt is the rate of change in velocity with respect to time...otherwise known as acceleration.
Force = mass * acceleration
Force = dp/dt = rate of change in momentum with respect to time.
A force applied to a mass causes a change in momentum.
In order for dv/dt = f, the mass must be 1 [unit].
When dealing with ordinary (non-relativistic) velocities and momentums we can assume mass is held constant.

I'll assume you mean velocity and force, and if the mass was left out, it's in there too. If the mass is also constant, then the only thing that this could correspond to is momentum, but this isn't a statement of conservation of momentum, it's Newton's second law.
The conservation of momentum would be stated as such:
dp/dt = 0 for a closed system.

Stagnation. No additional volume as in no time is evolving in their constantinouity of f!

You stated that f is a constant, therefore f is conserved, whatever f (and v) represent.
