The valve core 2 and the electromagnet assembly 3 are both arranged in the valve body 1, and the electromagnet assembly 3 is used for changing the position of the valve core 2 in the valve body 1.
The manual button assembly 4 is arranged at two ends of the valve body 1, the manual button assembly 4 comprises a shell 41, a cylindrical button 42, a positioning pin 43 and a pushing piece 44, the shell 41 is detachably connected with the valve body 1, the cylindrical button 42 is inserted in the shell 41, the pushing piece 44 penetrates through the shell 41, one end of the pushing piece 44 is connected with the cylindrical button 42, and the other end of the pushing piece 44 abuts against the valve core 2. One end of the positioning pin 43 is arranged on the cylindrical button 42, the other end of the positioning pin 43 is arranged in a clamping groove 411 on the inner wall of the shell 41, and the clamping groove 411 comprises an axial slideway 411a parallel to the axis of the cylindrical button 42 and a transverse slideway 411b perpendicular to the axis of the cylindrical button 42.
When the electromagnetic directional valve is in a non-energized debugging state, a worker can push the cylindrical button 42 to move in the housing 41 along the axial direction of the cylindrical button 42, so that the pushing piece 44 connected with the cylindrical button 42 is pushed to move, and the position of the valve core 2 pushed by the pushing piece 44 is changed. With the movement of the cylindrical button 42, the positioning pin 43 on the cylindrical button 42 moves in the axial slide 411a of the slot 411. When the valve core 2 moves to the right position, the positioning pin 43 on the cylindrical button 42 moves to the transverse slideway 411b of the clamping groove 411 at the moment, the cylindrical button 42 is rotated, the positioning pin 43 enters the transverse slideway 411b, the position of the cylindrical button 42 is fixed, and then the positions of the pushing piece 44 and the valve core 2 are fixed, so that the debugging requirements of the electromagnetic directional valve are met. The manual button does not need to be pressed for a long time by a worker, and the manual button does not need to be supported all the time by other devices, so that manpower and material resources in the debugging process of the electromagnetic directional valve can be saved. When the valve core 2 needs to be returned to the original position, the cylindrical button 42 is rotated, the positioning pin 43 moves to the axial slideway 411a, and then the cylindrical button 42 moves a certain distance in the direction back to the pushing piece 44.
It should be noted that this structure can be also adopted in the case where it is necessary to change the position of the valve element 2 in the electromagnetic directional valve under the condition that the electromagnetic directional valve is not energized.

When the positioning pin 43 is located in the transverse slideway 411b, the spring 45 is compressed by the cylindrical button 42, and when the cylindrical button 42 moves in a direction opposite to the pushing piece 44, the compressed spring 45 can apply certain thrust to the cylindrical button 42, so that the cylindrical button 42 automatically returns to the original position, and the valve core 2 also returns to the original position, and the arrangement facilitates accurate control of the position of the valve core 2.
Fig. 2 is a schematic structural diagram of a housing according to an embodiment of the present invention, and in conjunction with fig. 1 and fig. 2, the card slot 411 includes at least two axial sliding ways 411 a. The arrangement of the at least two axial slideways 411a facilitates the control of the cylindrical button 42 by the operator, and when the cylindrical button 42 is rotated, the cylindrical button 42 can be operated by selecting a convenient angle.
As shown in fig. 2, the manual button assembly 4 further includes a snap spring 46 disposed on an inner wall of the housing 41, the snap spring 46 is disposed coaxially with the cylindrical button 42, and the positioning pin 43 is located between the snap spring 46 and the pushing member 44. When the cylindrical button 42 moves to the outlet of the housing 41, the snap spring 46 will block the positioning pin 43 to prevent the cylindrical button 42 from being separated from the housing 41.
With reference to fig. 1 and 2, a pusher seal ring 6 may be disposed between the pusher 44 and the housing 41. The seal ring 6 may be disposed in the seal groove 41c of the housing 41.
