The setting of pre-positioning structure makes the bolt hole alignment fast and accurate, the machining difficulty is reduced, the machining efficiency is improved, the installation accuracy is improved, and the problem of structural appearance defects is solved.

Guide frame and electromagnetic reversing valve
ActiveCN102678956ARelieve pressureAvoid deformationOperating means/releasing devices for valvesMultiple way valvesEngineeringMechanical engineering
The invention provides a guide frame and an electromagnetic reversing valve.. The guide frame comprises a plate-shaped guide frame main body and a slide block mounting hole formed on the guide frame main body, and slide block mounting plates matched with the mounting parts of a sliding bock are arranged on the two end parts of the slide block mounting hole along the length direction of the guide frame main body. According to the guide frame and the electromagnetic reversing valve, as the slide block mounting plates matched with the mounting parts of the sliding bock are arranged on the two ends of the slide block mounting hole along the length direction of the guide frame main body, the side wall of each slide block mounting plate is matched with the outline of each mounting part of the sliding block, thus the matching area of the guide frame main body and the sliding block can be increased, the pressure applied to unit area of the sliding block is reduced, and the deformation or fragmentation of the sliding block can be avoided.
