Abstract
A valve assembly (6000) for use with a valve body (7000) having a valve seat (7112) is disclosed, the valve assembly (6000) comprising: a cartridge (6200) threadably engaged with and extending away from the valve body (7000); a poppet (6500) slidably engaged with the cartridge (6200); a plate (6600) engaged with the poppet (6500); a plunger (6400) slidably engaged with the cartridge (6200) and slidably extending through the plate (6600); and a retainer (6450) captured between the plate (6600) and a surface of the poppet (6500), wherein the retainer (6450) is threadably engaged with the plunger (6400). The valve assembly (6000) can regulate fluid flow.
Claims20
A valve for conveying fluid, comprising:
- a valve body comprising a valve seat and defining an inlet and an outlet in fluid communication with one another;
- a gland nut mounted to the valve body;
- a lower spindle threadably engaged to the valve body, wherein the lower spindle comprises an upper spindle engaging surface that defines an upper-spindle receiving bore;
- a seat disc mounted to the lower spindle;
- an upper spindle comprising a lower spindle engaging portion defining a biasing-member receiving bore, wherein the upper spindle is matingly engaged to the lower spindle such that rotation of the upper spindle causes the lower spindle to rotate, wherein the lower spindle engaging portion is received in the upper-spindle receiving bore to matingly engage the upper spindle to the lower spindle;
- and
- a biasing member at least partially disposed in the biasing-member receiving bore of the upper spindle and extending between the upper and lower spindles, wherein the biasing member is configured to bias the upper spindle into sealing engagement with the gland nut, wherein the valve is movable between a closed configuration in which the seat disc sealingly engages the valve seat and prevents fluid flow from the inlet to the outlet and an open configuration in which the seat disc is disengaged from the valve seat and enables fluid flow from the inlet to the outlet.
A manual valve module for a cryogenic cylinder control system comprising:
- a housing;
- and
- a manual valve supported by the housing, the manual valve comprising:
- a valve body comprising an upper portion, a lower portion, and a valve seat;
- a gland nut mounted to the valve body;
- a lower spindle threadably engaged to the lower portion of the valve body, wherein the lower spindle comprises an upper-spindle engaging surface that defines an upper-spindle receiving bore;
- an upper spindle disposed in the upper portion of the valve body, wherein the upper spindle comprises a lower-spindle engaging portion that defines a spring-receiving bore, wherein the lower-spindle engaging portion is received in the upper-spindle receiving bore to mate the upper spindle to the lower spindle such that rotation of the upper spindle causes rotation of the lower spindle;
- a seal disposed around a portion of the upper spindle;
- and
- a spring at least partially disposed in the spring-receiving bore and extending between the upper spindle and the lower spindle, wherein the spring is configured to exert a biasing force on the upper spindle to cause the seal to sealingly engage the gland nut.
