In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. As used herein, the word "comprising" and similar words are intended to mean that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items.
In order to solve the problems in the prior art, embodiments of the present invention provide an electromagnetic overflow valve set.
Examples
As shown in fig. 1 to 4, an electromagnetic overflow valve set comprises a rectangular valve body 1; a two-position two-way electromagnetic directional valve 2 and an external control overflow valve 3 are arranged on the rear side surface of the valve body 1; an oil source port 4 is arranged on the front side surface of the valve body 1; the oil source port 4 is connected with an oil source; an oil return opening 5 is formed in the right side surface of the valve body 1; the top of the valve body 1 is provided with a mounting hole 6;
the two-position two-way electromagnetic directional valve 2 comprises a first oil inlet 2-1 and a first oil outlet 2-2; the external control overflow valve 3 comprises a second oil inlet 3-1, a second oil outlet 3-2 and an external interface 3-3; a second oil inlet 3-1 of the external control overflow valve 3 is connected with an oil source port 4; a second oil outlet 3-2 of the external control overflow valve 3 is connected with an oil return port 5; the oil return port 5 is connected with an oil tank; an external port 3-3 of the external control overflow valve 3 is connected with a first oil inlet 2-1 of the two-position two-way electromagnetic directional valve 2; the first oil outlet 2-2 of the two-position two-way electromagnetic directional valve 2 is connected with an oil return port 5.
A pressure measuring port 7 is arranged on the left side surface of the valve body 1; the pressure measuring port 7 is connected with the oil source port 4; and a pressure gauge is arranged on the pressure measuring port 7.
The mounting holes 6 are three through holes arranged at the top of the valve body 1.

The valve body 1 is made of alloy steel.
The externally controlled overflow valve of the utility model is a pilot overflow valve.
The working principle of the utility model is as follows:
hydraulic oil enters from the oil source port 4, and when the two-position two-way electromagnetic valve 2 is not electrified, the first oil inlet 2-1 and the first oil outlet 2-2 of the two-position two-way electromagnetic valve 2 are in a closed state; the external control overflow valve 3 is in a normal unloading state, and the oil source port 4, a second oil inlet 3-1, a second oil outlet 3-2 and an oil return port 5 of the external control overflow valve 3 are communicated; namely, the oil source port 4 and the oil return port 5 are normally open;
when the two-position two-way electromagnetic valve 2 is electrified, namely a first oil inlet 2-1 and a first oil outlet 2-2 of the two-position two-way electromagnetic valve 2 are in an open state; the external control type overflow valve 3 is in a normally closed state, and a second oil outlet 3-2 of the external control type overflow valve is in a closed state; that is, the oil source port 4 is not communicated with the oil return port 5, and the unloading can be realized only from the oil source port 4 to the oil return port 5 when the pressure of the oil source port 4 reaches the set pressure of the external control overflow valve 3, so as to realize the requirement of adjusting the working pressure of the oil source port 4.
