As shown in Figure 1 to Figure 2,
Based on cleaning tail gas electromagnetic valve structure, include the valve body 1 being adapted and valve gap 2, valve body 1 offers air inlet 11
With gas outlet 12, passed through gas passage 13 between air inlet 11 and gas outlet 12 and be connected, valve gap 2 top was equipped with electric magnet group
Part, electromagnet assembly includes shell 31, coil brace 32, the coil 33 being wound on coil brace 32, is assemblied in coil brace
The sleeve pipe 34 at 32 centers, the sleeve pipe 34 interior energy dynamic iron core 35 moving up and down and the static iron core 36 being fixed on sleeve pipe 34 upper end, quiet
It is provided with antifreeze plate 4 between iron core 36 and described dynamic iron core 35, set between the inwall of the periphery of dynamic iron core 35 and described sleeve pipe 34
It is equipped with wear-resistant sleeve 5, matched with described gas passage 13 of crossing in the lower end of dynamic iron core 35；The bottom of valve body 1 is provided with heating plate 6.
Wear-resistant sleeve 5 is made using ptfe material；Ptfe: politef, is the high score aggregated by tetrafluoroethene
Sub- compound, has excellent chemical stability, corrosion resistance, sealing, high lubrication non-stick, electrical insulating property and good resisting
Aging endurance.
Wear-resistant sleeve 5 is set between the inwall of dynamic iron core 35 and sleeve pipe 34, dynamic iron core 35 can be prevented effectively from and be moved through
Rub with sleeve pipe 34 in journey, it is to avoid galling, so can improve service life.
In embodiment, it is provided with a pressure-releasing chamber 35a in dynamic iron core 35, the side wall of dynamic iron core 35 is formed with and described pressure-releasing chamber
The relief hole 35b that 35a is connected.
While dynamic iron core 35 moves up and down in sleeve pipe 34, amount of heat can be produced, and so that the temperature in valve is raised, temperature
The rising of degree can make the volume of gas increase, pressure increases；Setting pressure-releasing chamber 35a, and pressure-releasing chamber 35a passes through relief hole 35b electricity
The inner chamber of magnet valve communicates, so that the space of the inner chamber of electromagnetic valve and its connection increases, reduces valve by the increase in space
Interior pressure, thus play the effect of protection electromagnetic valve.
In embodiment, the lower end of dynamic iron core 35 is equipped with sealing gasket 35c, and sealing gasket 35c is matched with described gas passage 13 of crossing
