Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As Fig. 1, shown in Fig. 2, bi-bit bi-pass bidirection press control valve described in the utility model, comprise valve body 14, is located at valve gap 4 and the base 11 at valve body two ends Shang Xia 14, and above-mentioned parts form the utility model agent structure.
The interior valve pocket A10 that vertically is provided with of described valve body 14, can be provided with valve rod 9 in valve pocket A10 up or down, and on the valve body 14 of described valve pocket A10 both sides, correspondence is provided with gas port A15 and gas port B7, and the valve rod 9 between described gas port A15 and gas port B7 is provided with seal ring 8.It should be noted that, seal ring 8 positions are between gas port A15 and gas port B7 the time, and the utility model is in original state.
Described valve gap 4 internal upper parts laterally are provided with receiving cavity 1, receiving cavity 1 two ends are respectively equipped with valve A18 and valve B3, be provided with spool 2 between described valve A18 and valve B3, the interior bottom of described valve gap 4 is provided with valve pocket B20, valve pocket B20 is communicated with receiving cavity 1, valve pocket B20 and valve pocket A10 concentric arrange, and in described valve pocket B20, are provided with piston 19
The setting that offsets of described piston 19 and valve rod 9 upper ends, be provided with Returnning spring 13 between valve rod 9 lower ends and base 11.More specifically, in described base 11, be provided with adjusting screw 12, described Returnning spring 13 is located between valve rod 9 lower ends and adjusting screw 12.Described adjusting screw 12 is for regulating the elasticity coefficient of Returnning spring 13.
