Description

Technical Field

[0001] This utility model relates to the field of directional valve technology, specifically a two-position three-way electromagnetic directional valve. Background Technology

[0002] Traditional DN06 plate-type 2-position 3-way solenoid directional valves are large and heavy, making them somewhat cumbersome in practical applications, especially in situations with very limited installation space, where they are often unusable. This new valve, however, is smaller in size, with installation dimensions identical to the DN06 plate-type 2-position 3-way solenoid directional valve. This allows it to effectively replace traditional plate-type solenoid directional valves, enabling their use even in confined spaces.

[0003] According to Chinese patent "A Two-Position Three-Way Solenoid Directional Control Valve" (publication number CN216692243U), this patent includes a rectangular valve body with a two-position three-way solenoid valve core mounted on its rear side. Through holes are provided on both the front and rear sides of the valve body. The two-position three-way solenoid valve core includes an oil inlet, a first oil outlet, and a second oil outlet. A first adapter, a second adapter, and a third adapter are provided on the front side of the valve body. The oil inlet is connected to the first adapter; the first oil outlet is connected to the second adapter; and the second oil outlet is connected to the third adapter. Compared with traditional plate-type two-position three-way solenoid directional control valves, this utility model's two-position three-way solenoid directional control valve is smaller and lighter. It can effectively replace traditional plate-type solenoid directional control valves while maintaining the same mounting surface, and can still be used in confined spaces.

[0004] However, in actual use, the adapter of this patent is difficult to clean, and if it is not cleaned for a long time, it may become clogged, requiring cleaning to clear the blockage. Therefore, we need a two-position three-way solenoid directional valve. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a two-position three-way electromagnetic directional valve.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a two-position three-way electromagnetic reversing valve, comprising a valve body, a valve core mounted on the back of the valve body, through holes on the front and back of the valve body, a connector A on the front of the valve core, a connector B on the front of the connector A, a plurality of oil outlets A on the outer wall of the connector A, a plurality of oil outlets B on the outer wall of the connector B, a limiting mechanism inside the connector A, and a cleaning mechanism inside the connector A.

[0009] Preferably, the limiting mechanism includes three fixed connecting plates, each disposed on the inner wall of the valve core. One end of each fixed connecting plate is fixedly connected to the inner wall of the adapter A, and the other end is fixedly connected to a limiting ring. By setting the fixed connecting plates and limiting rings in the limiting mechanism, the range of motion of the cleaning mechanism can be effectively limited.

[0010] Preferably, the outer wall of the limiting ring and the outer wall of the fixing connecting plate are respectively fitted with sealing sleeves. By setting the sealing sleeves, effective sealing can be achieved when the mounting ring and the limiting ring are in contact with each other.

[0011] Preferably, the cleaning mechanism includes a sliding hole, which is formed at the top of the adapter A, and a movable rod is movably connected inside the sliding hole. By configuring the movable rod and the sliding hole in the cleaning mechanism to cooperate with each other, the mounting ring can be effectively moved horizontally.

[0012] Preferably, a limiting plate is fixedly connected to the top of the movable rod, and an operating ball is fixedly connected to the top of the limiting plate. The operating ball facilitates horizontal movement of the movable rod.

[0013] Preferably, a mounting ring is fixedly connected to the bottom end of the movable rod, and a brush is mounted on the back of the mounting ring. By setting the mounting ring, a brush machine can be effectively assembled for cleaning and unclogging purposes.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a two-position three-way electromagnetic directional valve, which has the following advantages:

Several oil outlets A5 are provided on the outer wall of the connector A3, and several oil outlets B6 are provided on the outer wall of the connector B4. A limiting mechanism 7 and a cleaning mechanism 8 are provided inside the connector A3. The limiting mechanism 7 includes three fixed connecting plates 701, each disposed on the inner wall of the valve core 2. One end of each fixed connecting plate 701 is fixedly connected to the inner wall of the valve core 2, and the other end is fixedly connected to a limiting ring 702. By setting the fixed connecting plates 701 and the limiting rings 702 in the limiting mechanism 7, the range of motion of the cleaning mechanism 8 can be effectively limited. Sealing sleeves are respectively fitted onto the outer wall of the limiting ring 702 and the outer wall of the fixed connecting plates 701. By setting a sealing sleeve, an effective seal can be achieved when the mounting ring 805 and the limiting ring 702 are in contact with each other.

[0026] In this embodiment, by setting the fixed connecting plate 701 and the limiting ring 702 in the limiting mechanism 7, the range of motion of its cleaning mechanism 8 can be effectively limited, and its sealing sleeve can effectively seal when the mounting ring 805 and the limiting ring 702 are in contact with each other.

By setting the movable rod 802 and the sliding hole 801 in the cleaning mechanism 8 to cooperate with each other, the mounting ring 805 can be effectively driven to move horizontally. The top end of the movable rod 802 is fixedly connected to a limiting plate 803, and the top of the limiting plate 803 is fixedly connected to an operating ball 804. The operating ball 804 facilitates the horizontal movement of the movable rod 802. The bottom end of the movable rod 802 is fixedly connected to the mounting ring 805, and a brush 806 is installed on the back of the mounting ring 805. By setting the mounting ring 805, the brush 806 can be effectively assembled to perform cleaning and unclogging effects.

[0029] In this embodiment, by setting the movable rod 802 and the sliding hole 801 in the cleaning mechanism 8 to cooperate with each other, the mounting ring 805 can be effectively driven to move horizontally. The mounting ring 805 can effectively assemble the brush machine 806 to perform cleaning and unclogging effects.

[0030] The working principle of this two-position three-way solenoid directional valve will be explained in detail below.

[0031] like Figure 1-3 As shown, during use, the fixed connecting plate 701 and the limiting ring 702 in the limiting mechanism 7 can effectively limit the range of motion of the cleaning mechanism 8. The sealing sleeve can effectively seal when the mounting ring 805 and the limiting ring 702 are in contact. Subsequently, the movable rod 802 and the sliding hole 801 in the cleaning mechanism 8 can cooperate to effectively drive the mounting ring 805 to move horizontally. The mounting ring 805 can effectively assemble the brush machine 806 to achieve the effects of cleaning and unclogging.
