Abstract
The utility model relates to the technical field of the valve industry, in particular to a novel cage type single-base regulating valve. The novel cage type single-base regulating valve comprises a valve deck, a valve body, a valve rod, a valve element, a sleeve, a valve deck sealing gasket and a valve base sealing gasket. The sleeve is tightly embedded in an inner cavity of the valve body in a sleeved mode. The valve element is tightly embedded in the sleeve and the inner cavity of the valve body in a sleeved mode. The valve rod is provided with a lower guide column matched with an inner cavity of the sleeve and is arranged over the valve element. A plurality of throttling holes are evenly formed in the side wall of the sleeve. The valve deck sealing gasket is arranged between the bottom end face of the valve deck and the top end face of the sleeve. The valve base sealing gasket is arranged between the inner cavity wall of the valve body and the bottom end face of the sleeve. When the novel cage type single-base regulating valve is used, the internal structure of the regulating valve is greatly simplified, and therefore two dies are omitted, and production cost is saved; one sealing gasket is omitted, and therefore sealing performance of the valve body is ensured. The novel cage type single-base regulating valve has the advantages of being simple in structure, reasonable in arrangement, low in manufacturing cost and the like.
