Abstract
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.
Claims20
A valve, comprising:
- a valve body having an inlet port, an outlet port, a flow passage extending between the inlet port and the outlet port, and an access port;
- a valve seat defined about the inlet port of the valve body;
- a compressible hanger supported by the valve body;
- a clapper supported by the hanger so that the clapper is movable between a closed position wherein the clapper engages the 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;
- and
- a closure member connected to the valve body to close the access port of the valve body, the closure member having an abutment surface in contact with the hanger so that the hanger is compressed between the closure member and the valve body.
A valve, comprising:
- a valve body having an inlet port, an outlet port, a flow passage extending between the inlet port and the outlet port, and an access port;
- a valve seat defined about the inlet port of the valve body;
- a spring positioned between the valve body and the access port of the valve body;
- a clapper connected to the spring so that the clapper is movable between a closed position wherein the clapper engages the 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;
- and
- a closure member removably connected to the valve body to selectively close and open the access port of the valve body, the closure member having an abutment surface in contact with the spring so as to compress the spring between the closure member and the valve body.
