Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings. the

As shown in Fig. 1 and Fig. 2, a valve island structure according to the present invention includes a valve base 1 and a number of solenoid valves 24 arranged side by side on the valve base 1, the bottom of the valve base 1 is provided with a groove 12, A circuit board 4 is arranged in the groove 12 , and the circuit board 4 is electrically connected to the electromagnetic pilot head assembly through the electric guide post 13 . That is, the valve base 1, several solenoid valves 24 and the circuit board 4 constitute the main structure of the present invention. the

The valve base 1 is provided with a main air inlet 15 , a main air outlet 14 and several working air ports 5 , and the solenoid valve 24 includes a valve body 2 . The valve body 2 is provided with an electromagnetic pilot assembly, the electromagnetic pilot assembly includes a coil 10, a moving iron core 9 and a static iron core 11 arranged in the coil 10, the moving iron core 9 and the static iron core 11 A compression spring C8 is arranged between them, which is mainly used for the automatic reset of the moving iron core 9. the

The valve body 2 is formed with an air inlet 16, an air outlet 17 and an exhaust port 18, the air inlet 16 communicates with the total air inlet 15, the air outlet 17 communicates with the working air port 5, and the exhaust The air port 18 communicates with the main exhaust port 14 , and the air outlet 17 is located between the air inlet 16 and the exhaust port 18 . the
