[0011] In another embodiment, the spring rod includes a first mounting plate and second mounting plates vertically fixed to both sides of the first mounting plate. The first mounting plate is fixedly connected to the first connecting seat through bolts and first connecting holes.

[0012] In another embodiment, the first mounting plate is provided with fifth connecting holes for mounting springs. Nuts are fixed on the springs, and the springs are fixed to the first mounting plate through screws passing through the fifth connecting holes and threadedly connected to the nuts.

[0013] In another embodiment, the mounting structure further includes a bottom fixing block. Arc-shaped grooves are respectively formed on the bottom fixing block and the valve seat body, and the arc-shaped grooves on both are arranged oppositely. The valve seat body and the bottom fixing block are fixed to the rocker arm shaft through bolts passing through both of them and the second connecting holes.

[0014] Due to the application of the above technical solutions, the present utility model has the following advantages compared with the prior art: The fixing of the solenoid valve seat does not require separate bolts.
