Embodiment
Below in conjunction with drawings and Examples, set forth the present invention further.In the following detailed description, the mode only by illustrating describes some one exemplary embodiment of the present invention.Undoubtedly, those of ordinary skill in the art can recognize, when without departing from the spirit and scope of the present invention, can revise by various different mode to described embodiment.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection domain of claim.
As shown in figures 1 and 3, a kind of multiple directional control valve based on single-ended oil sources management system, comprises oil inlet and oil return body 1, and on described oil inlet and oil return body 1, series connection is fixed with at least two commutation bodies 2; Described oil inlet and oil return body 1 is provided with total oil inlet P and total oil return inlet T;
Described commutation body 2 is provided with oil inlet passage R, the drainback passage O and unloading channel Q that are communicated with adjacent described commutation body 2; One-way valve 4 and relief valve 3 is provided with in described oil inlet and oil return body 1, described total oil inlet P is communicated with by the described oil inlet passage R of described one-way valve 4 with adjacent described commutation body 2, described total oil return inlet T is directly communicated with the described drainback passage O of adjacent described commutation body 2, is connected with described relief valve 3 between described total oil inlet P and described total oil return inlet T; Described total oil inlet P is directly communicated with the described unloading channel Q of adjacent described commutation body 2;
Described commutation body 2 is provided with the oil inlet P n(P be communicated with described oil inlet passage R and represents filler opening, n represents the position sequence of the commutation body 2 belonging to filler opening) and the oil return inlet T n(T that is communicated with described drainback passage O represent return opening, n represents the position sequence of the commutation body 2 belonging to return opening), described commutation body 2 is also provided with the actuator port A for operating hydraulically operated actuator and actuator port B; Be positioned at the tail end shutoff of the described oil inlet passage R of the described commutation body 2 of end, described drainback passage O and described unloading channel Q, as shown in Figure 4, the described unloading channel Q in the described commutation body 2 of end is communicated with described oil return inlet T n.
As shown in Figure 2, the junction surface between adjacent commutation body 2 is designed to common end face, and oil inlet passage R, the drainback passage O of total same position and size and unloading channel Q, process simple and convenient.When demand is different, between the commutation body 2 of multiple directional control valve, can adds arbitrarily or cut commutation body 2, just can realize the centralized control of multiple actuator.
When the spool of each commutation body 2 is all in neutral position, hydraulic oil flows to each commutation body 2 through total oil inlet P and does not work, when hydraulic oil arrival is positioned at the described commutation body 2 of end away from described oil inlet and oil return valve 1, hydraulic oil enters in the oil return inlet T n of end commutation body 2 from unloading channel Q, enter in drainback passage O by oil return inlet T n, then fuel tank is flowed back to through total oil return inlet T, the off-load of pressure oil circuit.When the spool of any one commutation body 2 does relative motion in valve body hole, make the corresponding oil circuit of this commutation body 2 switch on or off and change the direction of oil circuit, thus handle multiple actuator movement, realize required function.Owing to being positioned at the special structure form of the described commutation body 2 of end, total oil inlet P of this multiple directional control valve and total oil return inlet T can be arranged on an oil inlet and oil return body 1, using a lamellar body lesser than common multiple directional control valve when realizing identical function, saving material, reducing cost.
Owing to have employed technique scheme, by improving the internal oil passages of multiple directional control valve oil inlet and oil return body 1, optimizing the structure of multiple directional control valve oil inlet and oil return body 1, using a lamellar body lesser than common multiple directional control valve when realizing identical function, save material, reduce cost; Oil sources connects from one end of multiple directional control valve, not only makes the structure of multiple directional control valve compacter, also solves the problem that pipeline in use easily collides with and fractures, improves the reliability of multiple directional control valve, avoids the equipment failure because leakage of oil produces.
Technique scheme has been unified to commutate the connecting end surface of body 2, makes that oil circuit is simple, simple installation, is more conducive to batch production; And arbitrarily can change commutation body 2 quantity of multiple directional control valve according to the actual requirements, repacking is simple, and versatility is stronger, and more comprehensively, application area is wider for function.
Description of the invention provides in order to example with for the purpose of describing, and is not exhaustively or limit the invention to disclosed form.Selecting and describing embodiment is in order to principle of the present invention and practical application are better described, and enables those of ordinary skill in the art understand the present invention thus design the various embodiments with various amendment being suitable for special-purpose.
