2nd, the dynamic iron core 3 is movably set with dynamic iron core 3, static iron core 4 and coil block 5, sleeve pipe 2, the quiet iron is fixedly installed
Core 4, supports between dynamic iron core 3 and static iron core 4 and is provided with back-moving spring 6, coil block 5 is fixed at the outside of sleeve pipe 2.
2/2-way high-low pressure of the present invention all can the valve also first guide bracket including being used to isolate valve body 1 with pilot head
7 and diaphragm 8, the bottom of sleeve pipe 2 is fixedly connected by first guide bracket 7 with valve body 1, specifically, in the present embodiment, first guide bracket 7 with
Valve body 1 is threadedly coupled, and sleeve pipe 2 is threadedly coupled with first guide bracket 7, is installed more convenient.It is embedded between first guide bracket 7 and valve body 1 close
Seal 71, improves sealing.
Extension bar 9 is provided with valve body 1, the top of extension bar 9 passes through first guide bracket 7 and is fixedly connected with dynamic iron core 3, this reality
Apply in example, extension bar 9 is threadedly coupled with dynamic iron core 3, convenient disassembly.The bottom of extension bar 9, which is provided with to seal with valve port 13, to be coordinated
Seal 91, the outer peripheral edge sealing pressure of diaphragm 8 is between valve body 1 and first guide bracket 7, and the inner peripheral of diaphragm 8 is molded vertically
There are the deformations 84 being sheathed on outside extension bar 9, bottom and the extension bar 9 of deformations 84 are tightly fastened.
The 2/2-way magnetic valve that the present invention is provided, can be applied to the working environment of high pressure and low pressure simultaneously, by setting
First guide bracket 7, diaphragm 8 and extension bar 9 are put, isolating between pilot head and valve body 1 is effectively realized so that the fluid in valve body 1
Medium may not flow into pilot head, it is to avoid the damage of pilot head and leaking for fluid, and service life is longer, environment protecting compared with
It is good.
In the present embodiment, diaphragm 8 includes upper film portion 81, lower film portion 82 and outer portion 83, the periphery sealing pressure in upper film portion 81
Between first guide bracket 7 and valve body 1, lower film portion 82 is tightly fastened with extension bar 9, and the integration of outer portion 83 is connected to lower film portion 82
