Abstract

The invention discloses a tool assembly for assembly of a manual-selected valve. The tool assembly comprises a positioning tool, an end cover mounting device and a constant-load pressurizing sealing device, the positioning tool fixes and positions the manual-selected valve by arranging a base, a bracket connecting sleeve, a pressing sleeve and the like; and the end cover mounting device is provided with a bearing plate, an end cover hanging frame, a long pressing bolt and the like to assist in mounting and fixing of a center shaft and an end cover, and the constant-load pressurizing sealing device is provided with a connecting plate, a base frame, a loading bolt and the like to achieve pressurization between a valve body and a sealing steel ball so as to improve the sealing performance. Compared with the prior art, the tool assembly has the beneficial effects that the valve is conveniently assembled through the arrangement of the positioning tool, the end cover and the center shaft are rapidly installed through the end cover mounting device, parts are protected in place in the mounting process, damage to the parts is avoided, pressurization sealing between the sealing steel ball and the valve body is conveniently and rapidly completed through the constant-load pressurizing sealing device, the sealing effect is improved, and the use stability of the parts is improved.

Description

technical field [0001] The invention relates to the technical field of repairing aircraft parts, in particular to a tool assembly for assembling a manually selected valve. Background technique [0002] The manual selection valve is an important control part for the operation of the aircraft cargo door. It is used together with the cargo door actuator for the ground cargo loading operation to complete the opening and closing operation of the aircraft cargo door. The switch handle of the cargo door is installed on the control shaft of the manual selection valve. When the handle is turned again, the control shaft of the valve is manually selected to control the different sub-components inside the valve to switch the hydraulic oil circuit, to control the extension and retraction of the cargo door actuator, and to realize the opening and closing of the cargo door. [0003] At present, in the process of assembling the manual selection valve, due to the irregular shape of the main ...
