Abstract
A knife gate valve includes a shutoff apparatus and a valve stem in communication with the shutoff apparatus. The valve stem includes a threaded portion and a journaled portion above the threaded portion. The journaled portion has a diameter smaller than a diameter of the threaded portion. A head portion is sized and shaped to engage with a powered rotational tool. A yoke has a journal cutout through which the journaled portion of the valve stem is positioned. A vertical position of the valve stem is maintained by the yoke. The valve stem is rotatable within the yoke to operate the shutoff apparatus.
Claims18
A knife gate valve, comprising:
- a shutoff apparatus;
- a valve stem in communication with the shutoff apparatus, the valve stem comprising:
- a threaded portion,
- a journaled portion above the threaded portion, the journaled portion having a diameter smaller than a diameter of the threaded portion, and
- a head portion sized and shaped to engage with a powered rotational tool;
- and
- a yoke having a fixed portion and a removable portion secured along a common horizontal plane, the yoke having a journal cutout through the fixed portion and the removable portion through which the journaled portion of the valve stem is positioned, wherein a vertical position of the valve stem is maintained by the yoke, and wherein the valve stem is rotatable within the yoke to operate the shutoff apparatus.
A handwheel, comprising:
- an outer handle;
- and
- a center plate having a bottom portion and a top portion, wherein the bottom portion is sized and shaped to engage with a shaft or a valve stem, and wherein the top portion is sized and shaped to engage with a rotational socket.
A stemmed valve apparatus, comprising:
- a shutoff apparatus;
- a first valve stem in communication with the shutoff apparatus;
- a rotational transfer system in communication with the first valve stem;
- a second valve stem in communication with the rotational transfer system, the second valve stem having an end sized to engage with a powered rotational tool, wherein rotation of the second valve stem within the rotational transfer system causes the first valve stem to rotate, and wherein the rotation of the first and second valve stems operates the shutoff apparatus to open and close;
- and
- a handwheel comprising an outer handle and a center late the center late having a shaped cutout extending completely through the center plate, wherein the handwheel is insertably positioned over at least a portion of the second valve stem through the shaped cut-out.
An impact-driven valve, comprising:
- a shutoff apparatus;
- and
- a valve stem in communication with the shutoff apparatus, the valve stem comprising:
- a threaded portion;
- and
- a head portion at an upper aspect of the valve stem above the threaded portion sized and shaped to engage with a powered rotational tool.
