Integral plug-in mounting type hand-operated direction valve

Abstract

The invention discloses an integral plug-in mounting type manual reversing valve, and relates to the technical field of reversing valves. The manual reversing valve comprises a manual reversing valve body, a limiting inserting hole and a limiting inserting groove which are used in cooperation are formed in the manual reversing valve body, an operation mechanism which is used in cooperation is fixedly installed at one end of the manual reversing valve body, and the operation mechanism comprises an operation outer cylinder, a sliding guide frame, an operation inner rod and a fixing nut. The operating mechanism is provided with a limiting mechanism used in cooperation with the manual reversing valve body, and the limiting mechanism comprises a T-shaped inserting rod, a limiting spring, an annular air bag and a columnar air bag. Through the arrangement and use of the operating mechanism, convenience is provided for a knob of the fixing nut, so that convenience is provided for tight contact and rapid separation of the fixing nut and the sliding guide frame, convenience is provided for pulling and fixing of the operating inner rod, convenience is provided for adjustment of the relative length of the operating outer cylinder and the operating inner rod, and the operating efficiency is improved. Therefore, different operation requirements can be met, and the practicability is high.
