| 发明名称 | Flow rate control valve and assembly method therefor | ||
| 摘要 | A flow rate control valve, which is capable of controlling the flow rate of a fluid that flows between a pair of ports by displacing a rod, includes a valve mechanism in an axial direction. The valve mechanism includes a body having the ports and a pair of fluid passages through which fluid supplied from the ports flows. The valve mechanism includes a sub-body disposed in an interior of the body, and in which the rod is screw-engaged in an advancing and retracting manner. The valve mechanism also includes a tubular shaped seat connected to an end of the sub-body, including a seat structure to seat the rod thereon, and a hole that communicates between one of the fluid passages and another of the fluid passages. | ||

| 主权项 | 1. A flow rate control valve, which is capable of controlling the flow rate of a fluid that flows between a pair of ports by displacing a rod, comprising: a valve mechanism in an axial direction, the valve mechanism including: a body having the ports and a pair of fluid passages through which fluid supplied from the ports flows;a sub-body disposed in an interior of the body, and in which the rod is screw-engaged in an advancing and retracting manner; anda tubular shaped seat connected to an end of the sub-body, including a seat structure to seat the rod thereon,a hole that communicates between one of the fluid passages and another of the fluid passages, andan outwardly extending step above the hole that surrounds the end of the sub-body and that stops an end surface of the sub-body from moving past the outwardly extending step. | ||
