Abstract: An expanding gate valve and method is provided for bidirectional sealing capability against pressure, whether the direction of pressure is upstream or downstream. The bidirectional annular seat seals against the gate assembly against pressure from the normal wellhead direction, typically upstream. For sealing against pressure in the opposite direction, the seat is formed with an annular recess extending radially outwardly from the central bore of the annular seat so that a flex portion of the seat formed between the recess and the front sealing face of the annular seat at the central bore flexes toward the gate assembly against this pressure. The front face of the bidirectional seat forms a raised annular sealing portion on the flex portion of the seat adjacent the central bore to provide sealing contact with the gate assembly in the expanded condition when the flex portion flexes toward the gate assembly.

Abstract: A method and fluid connection system to fluidly connect a fracturing manifold to a fracturing tree. The method includes fluidly connecting a plurality of flexible flowlines between the manifold outlet of a fracturing manifold module and the fracturing tree such that fluid from the manifold outlet is distributed into the flexible flowlines and into the fracturing tree to avoid abrupt or right angle changes in direction in all fluid connections at the fracturing tree and between the manifold outlet and the fracturing tree. The fluid connection system includes a flow distribution block having a single inlet and a plurality of outlets, and distributes fluid flow between the single inlet and the plurality of outlets without abrupt or right angle changes in direction. The flexible flowlines have a first end fluidly connected to one of the plurality of outlets, and a second end fluidly connected to the fracturing tree.

Abstract: A low power consumption leak detection device for a toilet tank includes a water level switch disposed within the toilet tank having a float. The float moves with a water level within the toilet tank from a starting position to a lower position. An electronic circuit is configured to be electrically disconnected from a power source when the float is in the starting position. The electronic circuit is configured to be electrically connected to the power source when the float is in the lower position and activate a timer having a preset time limit, which if reached sends an alarm signal to an alarm indicator. The alarm indicator notifies a resident of a potential water leak problem that can be fixed. The lower power consumption leak detection device only uses power when the water level drops thereby greatly extending the life of the battery and usefulness of the device.
