Patent ES-402549-A1 (ES)
Title: Gate valve
IPC: F16K31/50
Filed: 1972-05-09
Abstract: The gate valve has a body portion with coaxial inlet and outlet openings in the side walls and valve body chamber with opposed converging valve seats. A wedge member has a body portion with a depending wedge shaped gate portion that is movable vertically into a valve chamber within the body portion to control the flow of fluid through the valve body portion. A cover member is secured to the upper face of the valve body and has an elongated chamber communicating with the valve chamber in which the wedge member moves vertically. A guide pin and valve stem are positioned within a cover chamber in spaced parallel relation to each other and on opposite sides of the longitudinal axis of the gate portion of the wedge member. The wedge member body portion has a longitudinal passageway on one side of the gate portion through which the guide pin extends. The wedge member body portion has a second vertical threaded passageway on the other side of the wedge member gate portion through which the threaded valve stem extends. Rotation of the valve stem moves the wedge member vertically within the chamber of the cover in a manner that the gate portion of the wedge control the flow of fluid through the valve body chamber. The valve body, because of the offset stem configuration, is relatively short in length and may be positioned between closely adjacent pipe flanges.
