Needle Valve and Associated Methods |
| 摘要 |
Exemplary embodiments are directed to a needle valve that generally includes a valve seat, a first stem in threaded engagement with a first stem thread, and a second stem in threaded engagement with a second stem thread. Rotation of the first stem advances the first stem and the second stem towards the valve seat by a distance that is equal to a combined thread pitch of the first stem thread and the second stem thread. Engagement of the first and second stems during rotation of the first stem defines a dual thread actuation mechanism. |
