Structure of Throttle Ports Any flow valve has a throttling port, commonly referred to as a throttle port, and its shape and size greatly affect the performance of the flow valve. Needle throttle, needle spool for axial movement, adjusting the size of the annular channel to regulate the flow. This throttle channel length, easy to plug, poor performance, but the structure is simple, easy to manufacture. Eccentric throttle, opened in the spool a triangular (or rectangular) eccentric groove, when the spool rotation, you can adjust the size of the channel. Its structure is also relatively simple, easy to manufacture, but the throttle channel is still longer, easy to block when the small flow, suitable for larger occasions. Axial triangular groove, open at the end of the spool one or two oblique triangular groove, the axial movement of the spool, you can change the size of the triangular groove through the flow section. The throttle flow through the triangle area, can be a smaller steady flow, but the throttle channel longer, suitable for small flow and performance requirements are not high occasions. China's production of Q-speed valve and L-type throttle valve to use more of this.
