Problems solved by technology

Unfortunately, many non-metallic drain valves for aircraft fuel tanks are not as strong as metal drain valves, and mishandling of a screwdriver that prematurely turns the valve before it has been pushed inward sufficiently can result in cracked and / or damaged drain valves
This can result in fuel loss and / or require a new drain valve, which can be expensive and time consuming to replace

Embodiment Construction

[0025] The following detailed description is merely exemplary in nature and is not intended to limit the various embodiments or their application and uses. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.

[0026] Various embodiments contemplated herein relate to tools for actuating valves, methods for manufacturing tools for actuating valves, and methods for actuating valves. Exemplary embodiments taught herein provide a tool including a shaft. The shaft extends longitudinally to define a longitudinal axis and is configured to transmit force to the valve to actuate the valve. In one example, the valve is a drain valve coupled to the bottom region of the fuel tank to provide fluid communication with the interior volume of the fuel tank for removing condensate and / or contaminants / deposits from the fuel tank.

[0027] The tool includes a body having a wall surrounding at least a portion of...

Abstract

Various non-limiting embodiments of a tool for actuating a valve, a method for making a tool for actuating a valve, and a method for actuating a valve, are provided. In one example, the tool includesa shaft defining a longitudinal axis and configured to transfer force to the valve for actuating the valve. A body has a wall surrounding a portion of the shaft. The wall defines a track that is formed therein and that has a track section substantially parallel to the longitudinal axis. A positive feature is coupled to the shaft and disposed in the track. The shaft is slidingly coupled to the bodyand when a force is applied to the shaft in a direction aligned with the longitudinal axis, the shaft moves relative to the body and the positive feature moves through the track section that restricts the shaft from being rotated about the longitudinal axis.

Description

technical field [0001] The technical field relates generally to valves, and more particularly to tools for actuating valves, such as drain valves for aircraft fuel tanks, methods for making such tools, and methods of using such tools to actuate valves. Background technique [0002] An aircraft fuel system has one or more fuel tanks for containing the fuel that powers the aircraft's engines. Fuel tanks may be located, for example, on the underside of the aircraft's fuselage, wings and / or empennage. Aircraft fuel tanks can accumulate condensate and / or contaminants / deposits over time and / or use. Condensation and / or contamination / deposits collect on the bottom of the fuel tank. If not removed, the condensate can freeze and expand in flight, clogging the inlets from the fuel tanks to the aircraft's engines. Likewise, contaminants / deposits can block the inlet from the fuel tank to the aircraft engine. Consequently, many aircraft fuel tanks have drain valves that provide access...
