Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
Example 1
As shown in fig. 1, the present invention discloses a solenoid valve with anti-blocking function, comprising: a valve body 1, a magnetic iron core 2 and a coil 3; the valve body 1 comprises from top to bottom: a first housing 11, a second housing 12, and a third housing 13; the first shell 11 is fixedly connected with the second shell 12, and the second shell 12 is fixedly connected with the third shell 13; the first shell 11 is provided with a water outlet 111, a liquid outlet cavity 112 is arranged in the water outlet 111, and a communication port 113 is arranged in the liquid outlet cavity 112; the second shell 12 is provided with a water inlet 121, a liquid inlet cavity 122 is arranged in the water inlet 121, the axes of the water inlet 121 and the water outlet 111 are parallel to each other, and the liquid inlet cavity 122 is communicated with the liquid outlet cavity 112 through a communication port 113; the magnetic iron core 2 is slidably disposed in the third housing 13, the magnetic iron core 2 and the communication port 113 are disposed on the same straight line, and the coil 3 is disposed around the outside of the magnetic iron core 2 and used for driving the magnetic iron core 2 to slide after being energized.
Specifically, the coil 3 is disposed inside the third housing 13.
Specifically, the third housing 13 is provided with: the sliding groove 131, the elastic piece 132 and the blocking piece 133; the sliding groove 131 is communicated with the communication port 113, the magnetic iron core 2 is arranged in the sliding groove 131 and slides in the sliding groove 131 under the action of the coil 3, the blocking piece 133 is arranged at the tail end of the sliding groove 131, the elastic piece 132 is arranged in the sliding groove 131, and two ends of the elastic piece 132 are respectively abutted to the magnetic iron core 2 and the blocking piece 133.
As shown in fig. 2, when the electromagnetic valve works, after the coil 3 is energized, an acting force generated on the magnetic iron core 2 is greater than the elastic force of the elastic member 132 and opposite to the elastic force of the elastic member 132, the elastic direction of the elastic member 132 is upward, the acting force of the coil 3 energized on the magnetic iron core 2 is downward, the magnetic iron core 2 overcomes the elastic force and slides downward, the elastic member 132 is compressed, the communication port 113 is opened, and the liquid inlet cavity 122 is communicated with the liquid outlet cavity 112; when the solenoid valve is closed, the coil 3 is not energized, and at this time, the coil 3 has no acting force on the magnetic core 2, and the elastic force of the elastic member 132 bounces the magnetic core 2 up to the communication opening 113, so as to close the communication opening 113.
Because the top end of the magnetic iron core 2 is higher than the communication port 113 during the drawing and inserting movement, the magnetic iron core 2 can effectively destroy the scale near the communication port 113 during the drawing and inserting movement, so that the scale of the communication port 113 cannot be formed into pieces; meanwhile, the magnetic iron core is used for sliding up and down in the sliding groove in spot check movement to remove and prevent scaling on the magnetic iron core, so that the situation that the electromagnetic valve cannot be used due to scaling on the surface of the magnetic iron core or scaling on the surface of the communication port is avoided.
