Abstract

The invention relates to a plug-in mounting type turnover control valve. The plug-in mounting type turnover control valve is characterized in by includinng a valve sleeve, a reversing valve element, aplug, a first spring and a second spring; an oil inlet, an oil return opening, a first working oil port and a second working port are arranged on the side wall of the valve sleeve; a first channel isarranged in the valve sleeve, the reversing valve element is slidably arranged in the first channel, a main control cavity and a secondary control cavity are formed in two sides of the reversing valve element, the first spring is arranged in the main control cavity, and the second spring is arranged in the secondary control cavity; and the reversing valve can be switched among the first position,the second position and the third position. The plug-in mounting type turnover control valve has simple structure, low manufacturing cost and compact size, and can achieve automatic turnover control0f a turnover plow.

Description

technical field [0001] The invention belongs to the technical field of hydraulic valves, in particular to a plug-in flip control valve. Background technique [0002] In recent years, most areas of my country have begun to promote the application of hydraulic turning plows. Using the reversing plow for plowing has the advantages of no opening and closing ridges, high production efficiency, and energy saving. The hydraulic reversing plow uses the hydraulic system of the tractor to control the left and right plow bodies to operate alternately, so as to achieve the purpose of no opening and closing ridges. Such as Image 6 As shown, the turning mechanism of the hydraulic turning plow mainly includes a suspension frame 111, a rotating shaft 115, a plow beam 112 and an oil cylinder 113. The rotating shaft 115 is welded on the suspension frame 111, and the plow beam 112 is installed on the rotating shaft 115. Respectively hinged on the suspension frame top and the plow beam 112 w...
