BACK PRESSURE REGULATION |
| 摘要 |
The invention generally provides a dynamic back pressure regulator. In an exemplary embodiment, the back pressure regulator includes an inlet, an outlet, a seat disposed between the inlet and the outlet and defining at least part of a fluid pathway, and a needle displaceable relative to the seat to form a restriction region therebetween for restricting fluid flow between the inlet and the outlet. In some embodiments, the needle can include a corrosion and/or erosion resistant polymer tip. |
