IMPROVED AUTOMATIC RECIRCULATION VALVE |
摘要 |
<p>An automatic recirculation valve having a body portion, a central hub integral with said body portion and inlet, main outlet and recirculation outlets. A main valve element responsive to flow from said inlet to said main outlet includes a hollow stem forming a bypass valve member through which recirculation fluid flows. A shaft guide bushing surrounding the valve stem and bypass adapter in the bypass outlet provides a recirculation fluid passage and imparts a swirling movement to the recirculation fluid exiting the recirculation outlet to protect the valve body and downstream piping from damage.</p> |
