THERMOSTATIC EXPANSION VALVE WITH CHECK VALVE |
摘要 |
A valve is provided that comprises a valve body including an inlet, an outlet, and a check valve chamber having an opening through the side of the valve body. The valve has a cover secured within the side opening in the valve body. A first valve opening is disposed between the inlet chamber and outlet chamber. A control valve is movable relative to the first valve opening to regulate fluid flow through the first opening when fluid flow is in the inlet-to-outlet direction, and is movable to engage the first valve opening to restrict fluid flow in the outlet-to-inlet direction. The valve comprises a second valve opening disposed between the check valve chamber and the outlet chamber. A check valve member is movable relative to the second valve opening to restrict forward flow and permit reverse flow through the second valve opening. |
