Split gate valve
First Claim
1. A system, comprising:
- a split gate valve, comprising;
a body having a bore and a cavity;
first and second gate sections coupled together and configured to move together within the cavity of the split gate valve along a path of travel between an open position and a closed position relative to the bore, wherein the first and second gate sections comprise respective first and second openings that selectively align with the bore in the open position;
a biasing mechanism disposed between the first and second gate sections, wherein the biasing mechanism biases the first and second gate sections away from one another to form opposite seals with opposite seats of the split gate valve along an entirety of the path of travel;
a rolling actuator configured to reduce friction and to convert a rotational input into a linear motion to move the first and second gate sections along the path of travel between the open and closed positions, wherein the rolling actuator comprises a plurality of rollers or a plurality of balls disposed along a spiraling path; and
wherein the split gate valve comprises at least one of;
the biasing mechanism comprises a cam mechanism;
the biasing mechanism comprises an elastic material that is not a spring;
orthe cavity has a substantially rectangular perimeter with four flat interior sides that extend along an axis through the body from a first side toward a second side, and the first and second gate sections collectively define four flat exterior sides disposed along the four flat interior sides of the cavity.

Abstract
Provided in some embodiments is a system that includes a split gate valve including first and second gate sections coupled together and configured to move together within a cavity of the split gate valve between an open position and a closed position. The split gate valve includes a rolling actuator to reduce friction and to convert a rotational input into a linear motion to move the first and second gate sections between the open and closed positions. In other embodiments is provided a method that includes converting a rotational input into a linear motion to activate a split gate valve via a rolling actuator. The method also includes seating first and second gate sections of the split gate valve against opposite first and second seats to provide a double seal.
