Embodiment:

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Embodiment one

As shown in Figure 1; A kind of piped gas relief valve; Be made up of pressure-sensitive trigger A, triggering cut-off valve B, screw 1, block 2, sealing film 3, metal splint 4, pressure regulation nut 5, locating washer 6, vent 7, the trigger 8 that automatically resets, stage clip 9, trigger arm 10, long spiro nail 11, knob spring 12, clamping nut 13, valve rod 14, valve pocket 15, valve pocket stage clip 16, valve opening 17, valve body 18, its characteristics are: pressure-sensitive trigger A is two positions on the same valve body 18 with triggering cut-off valve B; Screw 1 will block a shot 2 with valve body 18 be linked together; Metal splint 4 is clipped on the center of circle of sealing film 3 and is fixed on the trigger 8 that automatically resets; The trigger 8 that automatically resets is fixed on the metal splint 4 at sealing film 3 centers through screw thread, and the trigger 8 that automatically resets can only be done displacement up or down under the qualification of locating washer 6; Locating washer 6 can move up and down in stage clip 9, pressure regulation nut 5 and the locating slot in 2 of blocking a shot; Clamping nut 13 pushes up valve rod 14 to valve body 18 through valve pocket stage clip 16; Long spiro nail 11 is fixed on trigger arm 10 and knob spring 12 on the valve rod 14.
