Abstract
A valve for conveying fluid has a closed position and an open position and comprises a body, a valve seat disposed in the body, a holder disposed in the body, and a valve seat disc. The valve seat comprises one or more inner surfaces and an outer surface, and the one or more inner surfaces define an inner void. The valve seat disc is connected to and movable with the holder between a first position in which the valve seat disc sealingly engages the outer surface of the valve seat and a second position in which the valve seat disc is disengaged from the outer surface of the valve seat. The valve is in the closed position when the valve seat disc is in the first position and the valve is in the open position when the valve seat disc is in the second position.
Claims16
A valve for conveying fluid, the valve having a closed position and an open position and comprising:
- a body;
- a valve seat disposed in the body, the valve seat comprising one or more inner surfaces and an outer surface, the one or more inner surfaces defining an inner void, wherein the valve seat contacts one or more inner surfaces of the body, wherein the body is made from a first material and the valve seat is made from a different second material, and wherein the first material of the body includes a greater coefficient of thermal expansion than the second material of the valve seat;
- a holder disposed in the body;
- and
- a valve seat disc connected to and movable with the holder between a first position in which the valve seat disc sealingly engages the outer surface of the valve seat and a second position in which the valve seat disc is disengaged from the outer surface of the valve seat,
- wherein the valve is in the closed position when the valve seat disc is in the first position and the valve is in the open position when the valve seat disc is in the second position.
A valve for conveying fluid, the valve having a closed position and an open position and comprising:
- a body;
- a valve seat disposed in the body, the valve seat comprising one or more inner surfaces and an outer surface, the one or more inner surfaces defining an inner void;
- a holder disposed in the body, wherein the holder includes an outer wall, an inner wall, and an annular connecting wall extending between and connected to each of the outer wall and the inner wall;
- and
- a valve seat disc connected to and movable with the holder between a first position in which the valve seat disc sealingly engages the outer surface of the valve seat and a second position in which the valve seat disc is disengaged from the outer surface of the valve seat,
- wherein the outer wall, the inner wall and the annular connecting wall of the holder define a receiving bore and a receiving void configured to receive and retain the valve seat disc,
- wherein the valve seat disc includes a seat disc body and a seat disc head extending from the seat disc body, and wherein the seat disc body is received in the receiving void and the seat disc head extends through the receiving bore, and
- wherein the valve is in the closed position when the valve seat disc is in the first position and the valve is in the open position when the valve seat disc is in the second position.
