[0023] In order to make the purpose, technical scheme and advantages of the utility model more clear and explicit, the utility model is further described in detail below in combination with specific implementation manners and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of the known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0024] As Figs. 1-3As shown, the utility model provides a kind of electromagnetic valve valve structure, including valve body 11, the top of valve body 11 is equipped with valve seat 12, and inlet end seat 13 and outlet end seat 14 are shaped along the medium transmission direction respectively;

[0025] The upper portion of valve seat 12 is equipped with driving device 21, and the valve stem 22 connected to the output end of driving device 21 penetrates the valve cavity of valve body 11, and driving device 21 is controlled by control device 23 to open and close;

[0026] One side of inlet end seat 13 is shaped with conduit 3, and the other end of conduit 3 is connected with hollow drain end seat 4.

[0027] The drain mechanism includes a motor 51 symmetrically installed on the conduit 3, and the output end of the motor 51 is connected with a shaft 52 that penetrates the drain end seat 4. The outer side of the shaft 52 is sleeved with a shaft sleeve 53, and the shaft sleeve 53 is shaped with a drain plate 55. The drain plate 55 is provided with a plurality of water guide grooves 56.

[0028] It should be noted that the valve stem 22 controlled by the output end of the driving device 21 moves up and down along the valve cavity clamped by the valve body 11 and the valve seat 12, driving the valve core connected thereto to control the on-off of the valve cavity passage. When the valve core is attached to the valve cavity passage, the passage between the inlet end seat 13 and the outlet end seat 14 is in a closed state. Conversely, when the valve core is separated from the valve cavity passage, the passage between the inlet end seat 13 and the outlet end seat 14 is in an open state.

[0029] In this embodiment, the drain mechanism is installed on the conduit 3 at the inlet end seat 13. When the medium transmission needs to be reduced, the drain plates 55 can be rotated in opposite directions. Since the drain plates 55 are symmetrically arranged, they are controlled to rotate by the shaft 52, and the rotation directions of the two are 180° clockwise and counterclockwise respectively. They can rotate the same angle, forming inclined drain slope structures in front and back of the drain end seat 4, and cooperating with the through drain grooves 56 to buffer the medium flow rate, preventing the medium from impacting the valve cavity clamped by the valve body 11 and the valve seat 12 at too high a flow rate, and ensuring the sealing stability of the electromagnetic valve after long-term use.

[0030] It can be understood that when the two drain plates 55 are at the front and back of the drain end seat 4 with an included angle of 180°, the drain end seat 4 is in a through state, and the medium enters the valve cavity passage of the electromagnetic valve at a normal flow rate for transmission.

[0031] In order to facilitate the gathering of the transmission medium, further, the conduit 3 connected to the inlet end seat 13 is a "frustum" structure that gradually narrows along the medium transmission direction. After the transmission medium is pretreated by the drain end seat 4, it converges to the passage between the inlet end seat 13 and the outlet end seat 14 along the inner wall of the conical conduit 3.

[0032] In order to ensure the stable rotation of the shaft 52, further, the side wall of the hydrophobic end seat 4 is symmetrically provided with a bearing 54, and one end of the shaft 52 penetrates the hydrophobic end seat 4 and rotates along the inner cavity of the bearing 54.

[0033] It should be understood that the above specific embodiments of the present application are only used for illustrative or explanatory purposes of the principles of the present application, and do not constitute a limitation on the present application. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present application shall be included in the protection scope of the present application. In addition, the appended claims of the present application are intended to cover all variations and modifications falling within the scope and boundary of the appended claims, or the equivalent forms of such scope and boundary.
