A gasket 9 is arranged between the table top at the left end part of the pole shoe 10 and the coil frame 17.
The coil rack 17 and the components arranged inside the shell 2 from right to left comprise a push rod sleeve 7, a separation pin seat 6, a pin guide sleeve 4, a ball guide sleeve 3, a push rod 1 and an end cover 18; a mandril 8 penetrates through the centers of the pole shoe 10 and the mandril sleeve 7, a right steel ball 19 is arranged at the left end part of the mandril 8 between the mandril sleeve 7 and the separation pin seat 6, a separation pin 5 penetrates through the centers of the separation pin seat 6 and the pin guide sleeve 4 at the left side of the right steel ball 19, and a left steel ball 20 is arranged between the left end of the separation pin 5 and the ball guide sleeve 3 and between the left end of the separation pin 5 and the push rod 1.
The middle part of the end cover 18 is provided with a port P1; an L-shaped opening is formed in the position, where the push rod 1 is arranged, of the shell 2; a port P2 is arranged at the position where the ball guide sleeve 3 is arranged on the shell 2; an opening A is formed in the middle of the shell 2 where the pin guide sleeve 4 is arranged; and a port B is arranged on the shell 2 at a position between the ejector rod sleeve 7 and the separation pin seat 6.
The invention is an improvement on the basis of the existing electromagnetic valve, the structure is the main structure of the electromagnetic valve, and other structural details are shown in figures 1-3.
Specifically, when the present invention is installed, the permanent magnet 14 is mounted on the coil frame 17, the permanent magnet 14 mainly provides a magnetic field, then the coil 15 is wound on the coil frame 17, then one end of the outgoing wire is welded on the coil 15, and penetrates out of the permanent magnet 14, and the other end of the outgoing wire is welded with the pin of the electric plug 12, and the electric plug 12 is welded on the coil cover 16, so as to form the coil assembly, as shown in fig. 2.

The main components of the invention function and require: the shell 2 provides the functions of fixing parts in the electromagnetic valve and connecting a product with a host. The steel ball and the ball guide sleeve 3 form the opening and closing function of the internal oil circuit. The electromagnetic valve provides electromagnetic acting force for remote control on opening and closing of the product valve. The electrical plug 12 provides an interface for the product to make electrical connections with a host. The permanent magnet 14 provides a position-locking magnetic force for the product. The sealing sharp edge of the ball guide sleeve 3 is an important part for ensuring the sealing performance of the product and should keep the accurate processing state.
The working principle of the invention is as follows: when the solenoid valve coil 15 is electrified, the electromagnetic force overcomes the attraction of the magnetic field of the permanent magnet 14 to the armature 11 and the hydraulic pressure at the oil port P1 acted on the separation pin 5, so that the armature 11 moves leftwards to a stop position, and the valve of the right steel ball 19 closes the oil circuit of the port B and the port A through the ejector rod 8 and the separation pin 5; the valve of the left steel ball 20 is opened, the oil circuit of the port P2 and the port A is communicated, when the hydraulic pressure at the port P1 is smaller, the pressure of the port P2 is 8MPa, the pressure of the port P1 is smaller than 3MPa, the electromagnet coil 15 is powered on and then is powered off, due to the action of the magnetic field suction force of the permanent magnet 14, the armature 11 still keeps the position when powered on, and the valve of the right steel ball 19 closes the oil circuit of the port B and the port A; the valve of the left steel ball 20 is opened to connect the oil circuit of the P2 port and the A port, when the electromagnet 14 is powered off, when the pressure of the P1 port rises to a certain value, the pressure of the P2 oil port is 8MPa, the pressure of the P1 oil port is more than 4MPa, the hydraulic pressure pushes the ejector rod 8 to overcome the suction force of the magnetic field of the permanent magnet 14 to the armature 11, the armature 11 is moved rightwards to a stop position, the valve of the right steel ball 19 is pushed to close the oil circuit of the P2 port and the A port, the valve of the right steel ball 19 is pushed to open through the separating pin 5, and the oil circuit of the B port and the A port is connected. When the pressure of the port P1 is reduced, the armature 11 is still kept at the right limit position due to the attraction force of the magnetic field of the permanent magnet 14, so that the oil path between the port P2 and the port A is closed, and the oil path between the port B and the port A is communicated.
