Integrated rotary table type reversing valve

Abstract

The invention discloses an integrated rotary table type reversing valve and belongs to the technical field of direction control valves. According to the technical scheme, the integrated rotary table type reversing valve comprises an upper valve block, a rotary table, a rotating shaft and the like. The upper part of the rotating shaft is provided with a reversing rotary knob. The upper valve blockand the rotary table are arranged on the middle of the rotating shaft, the bottom of the upper valve block is provided with a cylindrical groove, and the rotary table is arranged in the cylindrical groove of the upper valve block. The middle part of the rotating shaft penetrates through the upper valve block and a through hole of the rotary table to be installed in a shaft hole of a middle valve block. The upper valve block, the middle valve block and a lower valve block are sequentially fixed through bolts from top to bottom. The periphery of the rotary table is provided with a plurality of U-shaped grooves, the lower surface of the rotary table is provided with three sets of annular grooves, and each annular groove is internally provided with two or more steps. The center of the lower surface of the rotary table is provided with a long groove. A synchronous hinge pin passes through a hinge pin hole and the long groove to fix the rotating shaft and the rotary table. Heads of positioning screws are clamped in the U-shaped grooves in the periphery of the rotary table to fix the rotary table. The reversing valve has the advantages that a reversing valve set is easy to control, the production efficiency is high and the like.

Description

technical field [0001] The invention belongs to the technical field of directional control valves, in particular to an integrated turntable reversing valve. Background technique [0002] In the current era of industrialization, in order to improve the convenience, utilization rate and automation of equipment, people often integrate multiple application functions on the same equipment. At the same time, considering cost reduction and energy saving, only one drive system is installed in the equipment to achieve multiple functions. The basic principle is to design multiple loops in the entire working system, and to realize multiple functions of the equipment through switching between different loops. [0003] In the traditional hydropneumatic system, multiple sets of reversing valve groups are used to switch between various functional circuits. But usually, the more functions the equipment has, the more reversing valve groups, the more complex the system, the more cumbersome ...
