发明名称 Check valve
摘要 A top entry check valve including a valve body with an access port. A compressible hanger body engages a portion of the valve body and is positioned in alignment with the access port of the valve body. A clapper is connected to the hanger body so that the clapper is movable between a closed position wherein the clapper engages a valve seat to occlude the passage of fluid through the fluid flow passage and an open position wherein the clapper is moved away from the valve seat to permit passage of fluid through the fluid flow passage. A closure member is connected to the valve body to close the access port of the valve body. The closure member has an abutment surface engaging the hanger body so that the hanger body is compressed between the closure member and the valve body.
