Embodiment Construction

[0031] refer to figure 1 and figure 2 , figure 1 Schematic diagram of the structure of the guide frame provided by the embodiment of the present invention; figure 2 for figure 1 Schematic of the guide frame shown with the slide mounted.

[0032] Such as figure 1 and 2 As shown, the guide frame provided by this embodiment includes a plate-shaped guide frame body 1 and a slider mounting hole 2 provided on the guide frame body 1. The slider mounting hole 2 is along the two ends of the guide frame body 1 in the length direction. The part has a slider mounting plate 3 for cooperating with the mounting part of the slider.

[0033] In the guide frame provided by this embodiment, the slider 4 is installed in the slider mounting hole 2 of the guide frame. In practical applications, pistons are installed at both ends of the guide frame, and the guide frame is arranged on the valve of the main valve of the electromagnetic reversing valve. In the chamber, the piston drives the gu...

Abstract

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.

Description

technical field [0001] The invention relates to refrigeration and air-conditioning technology, in particular to a guide frame and an electromagnetic reversing valve, belonging to the field of refrigeration equipment. Background technique [0002] In the air-conditioning system, the solenoid valve is usually used to change the flow direction of the refrigerant in the air-conditioning system to realize the conversion between the cooling mode and the heating mode. [0003] The existing electromagnetic reversing valve includes a main valve, a pilot valve and an electromagnetic coil. The electromagnetic coil is installed on the pilot valve. Reversing, and through the switching of the main valve to the pipeline, the change of the refrigerant flow direction is realized, so that the air conditioning system can realize cooling in summer and heating in winter. [0004] The main valve consists of an injection molded slider and a guide frame to which the slider is attached. The guide ...
