Abstract
A gate valve has a housing, a valving element in the housing, and a seat in the housing which cooperates with the valving element and extends transverse to the flow direction. The valving element is carried by a spindle which serves to move the valving element into and out of engagement with the seat. A support for the spindle is disposed in the housing and has a central, outwardly directed flange which defines a passage for the spindle. The flange is coupled to the spindle in the region of the valving element so that the support moves with the spindle. The support is in sliding engagement with the internal surface of the housing to thus guide the spindle and support the latter against transverse forces generated by flow through the housing.
Claims15
A valve, comprising a housing having an internal surface;
- a valving element in said housing;
- a seat in said housing;
- an actuating element arranged to move said valving element into and out of engagement with said seat;
- and a support for supporting said actuating element against transverse forces generated by flow of a fluid through said housing, said support being mounted on said actuating element and being in sliding contact with said internal surface, and said valving element being mounted on said actuating element separately from said support.
A valve, comprising a housing having an internal surface;
- a valving element in said housing;
- a seat in said housing;
- an actuating element connected to said valving element and being arranged to move said valving element into and out of engagement with said seat;
- and a support for supporting said actuating element against transverse forces generated by flow of a fluid through said housing, said support being coupled to said actuating element for movement therewith and being in sliding contact with said internal surface, and said support having a coupling portion for establishing a connection with said actuating element, a guiding portion which engages said internal surface, and a tubular portion intermediate said coupling portion and said guiding portion.
