The invention relates to hydraulic elements and provides a two-way over-travel and automatic-resetting mechanically-actuated valve which is particularly applicable to occasions in which the travel of a collision block is difficult to accurately control, a valve core needs two-way driving and difficultly bears larger radial force, and the like. The mechanically-actuated valve comprises a base plate, a reversing valve, a pin, a valve core driving assembly, a valve core resetting assembly, a locating sleeve, a connecting rack, a blocking plate, a bracket assembly, a small locking nut, a big locking nut, and the like. According to the mechanically-actuated valve provided by the invention, the over-travel can be realized, namely, the travel of the collision block is allowed to exceed that of the valve core, so that in-place movement of the valve core can be guaranteed under the collision of the collision block and the valve core can be prevented from being damaged due to overlarge stress; and when the valve core is not subjected to collision, the automatic resetting of the valve core can be realized.
Description
technical field [0001] The invention relates to a hydraulic component, in particular to a motorized valve with two-way overtravel and automatic reset. Background technique [0002] The motorized valve directly or indirectly impacts the hydraulic valve spool to move it through the impact block installed on the moving parts, thereby switching the oil circuit. The disadvantage of the motorized valve in the prior art is that the stroke of the bumper needs to be precisely controlled. If the stroke is too small, the movement of the valve core will not be in place. Two functions. Contents of the invention [0003] The object of the present invention is to provide a two-way overrunning and automatic reset motorized valve in order to overcome the problems of precise control and one-way drive of the stroke of the motorized valve bumper in the prior art. The motorized valve of the present invention can realize an overrunning stroke, that is, allow the stroke of the bumper to excee...
