[0016] The features and illustrative embodiments of various aspects of the present invention will be described in detail below. In the detailed description below, many specific details are set forth in order to provide a comprehensive understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention. The present invention is in no way limited to any specific arrangement and method set forth below, but rather covers any improvements, replacements, and modifications of structures, methods, and devices without departing from the spirit of the present invention. In the accompanying drawings and the following description, well-known structures and techniques are not shown to avoid unnecessary ambiguity in the present invention.

[0017] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other, and the embodiments can refer to and quote each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] like Figure 1 As shown, the utility model proposes a solenoid valve with a connector, including a valve seat 1, a push rod 2, a valve core 3, an electromagnet 4, a magnetic circuit skeleton 5, a spring 6, a sleeve 7, and a connector 8. The valve seat 1 is provided with a valve seat hole, the push rod 2 is slidably arranged in the valve seat hole, the valve core 3 is slidably arranged in the inner hole of the magnetic circuit skeleton 5, the rear end of the push rod 2 is in contact with the valve core 3, the electromagnet 4 is arranged on the magnetic circuit skeleton 5, one end of the spring 6 is arranged in the countersunk hole of the valve core 3, and the other end is arranged in the countersunk hole 41 of the electromagnet 4, the electromagnet 4 is connected to the connector 8 through the sleeve 7, and the electromagnet 4 and the connector 8 are electrically connected through two wires.

[0019] In the present invention, the outer circular surface of the valve core 3 is provided with 3 pressure equalizing grooves. When the valve core moves, the pressure equalizing grooves can cause the liquid flow to form vortices in the grooves, thereby consuming part of the liquid force, reducing the axial thrust on the valve core 3, and preventing the occurrence of hydraulic clamping.

[0020] In the present invention, the front end of the sleeve 7 is interference-fitted to the rear end of the electromagnet 4, which ensures a reliable connection and is also convenient for disassembly.

[0021] In the present invention, the connector 8 is interference-mounted at the rear end of the sleeve 7. The connector 8 is made of titanium alloy material and adopts a structural form in which the titanium alloy connector 8 and the electromagnet 4 are interference-connected through the sleeve 7. It has the characteristics of light weight, compact structure, and corrosion resistance.

[0022] In the present invention, the end face of the magnetic circuit skeleton 5 is provided with a positioning pin to prevent mis-insertion, and the positioning pin cooperates with the positioning hole of the upper system to ensure that the oil hole on the valve seat 1 corresponds to the position of the oil supply hole of the upper system.

[0023] In the present invention, an elastic retaining ring is provided between the mounting housing of the electromagnet 4 and the body of the electromagnet 4 to prevent the housing of the electromagnet 4 and the body of the electromagnet 4 from rotating relative to each other.

[0024] In the present invention, a filter is provided at the end of the valve seat 1 to ensure that the system oil entering the valve seat 1 remains clean and does not contain impurities.

[0025] The working principle of the utility model is as follows: after hydraulic oil is introduced into the solenoid valve from the left filter, before the connector 8 is energized, the spring 6, under the action of the compression force, causes the valve core 3 and the push rod 2 to be subjected to a horizontal force to the left. At this time, the solenoid valve 4 is in a closed state. When the connector 8 is energized, the electromagnetic force gradually increases with the increase of the voltage. When the electromagnetic force exceeds the force of the spring 6, the valve core 3 and the push rod 2 will move to the left under the action of the electromagnetic force. At this time, the solenoid valve 4 is in an open state. Therefore, the solenoid valve of the utility model has the characteristics of light weight, compact structure, and corrosion resistance. It can be widely used in the pre-stage of reversing valves and various integrated valves, and is widely used in aerospace, engineering machinery, metallurgy, shipbuilding and other fields.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present invention, and these modifications or replacements should all be included in the protection scope of the present invention.
