　　進口蒸汽流量調節閥product deion:

　　進口蒸汽流量調節閥the utility model comprises a valve body, in which a valve cavity connecting the water inlet channel and the water outlet channel is arranged; a valve cover fixedly arranged on the top of the valve body; a valve seat installed at the bottom of the valve cavity; a sleeve located in the valve cavity, and a guide hole is arranged on the sleeve;

　　a cylindrical valve core located in the sleeve;進口蒸汽流量調節閥 and a valve rod, the upper end of the valve rod is driven and connected with the driving part, and the lower end is connected with the cylindrical valve core located in the sleeve; the outer cylinder surface of the cylindrical valve core is provided with upper and lower guide sealing rings.進口蒸汽流量調節閥 when the cylindrical valve core is at the minimum opening, the guide hole on the sleeve is between the upper and lower guide sealing rings. when the cylindrical valve core is at the maximum opening, the guide hole on the sleeve is below the lower guide sealing ring. it effectively improves the sealing performance between the cylindrical valve core and the sleeve, prevents medium leakage, and also plays the role of sliding guidance of the cylindrical valve core, reducing friction and silencing.
