Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of novel residual voltage relief valve described in the utility model, comprise valve body 10, be located in valve body 10, can slide up and down piston 11 and valve rod 12, and the inlet hole 15 and the air outlet hole 16 that lay respectively at valve body 10 two ends, left and right, in described valve body 10, be provided with dividing plate 18, on dividing plate 18, have the switch hole 19 that is communicated with lower inner cavity on valve body 10, valve rod 12 upper ends are connected with piston 11 through switch hole 19, valve rod 12 lower ends are provided with spool 13, described spool 13 is and mates setting with switch hole 19, valve body 10 bottoms are provided with the bottom 14 coordinating with spool 13, described inlet hole 15 and air outlet hole 16 are communicated with respectively the inner chamber of the valve body 10 of dividing plate 18 both sides, valve body 10 upper ends are provided with knob 20, between knob 20 and piston 11, are provided with spring seat 21, and spring seat 21 is connected with piston 11 by stage clip 22.
Above-mentioned parts are the utility model agent structure.
Described spool 13 two ends are all conical surface setting, and the external diameter of spool 13 is greater than the diameter of switch hole 19, and spool 13 rises afterwards and dividing plate 18 is conflicted and stop up switch hole 19, and then the gas circuit of sealing inlet hole 15.
On described bottom 14, have relief hole 17, relief hole 17 upper ends are communicated with air outlet hole 16 and internal diameter is less than spool 13 external diameters, after spool 13 declines and bottom 14 conflict and stop up relief hole 17, and then inlet hole and air outlet hole 15 are communicated with by switch hole 19.
