Specific embodiment
Such as the embodiment that Fig. 1 to Fig. 3 is shown in Figure of description: a kind of electronic relief valve, including main valve 1, connector 2
With pneumatic control valve 3, main valve 1 is made of valve body 4 and valve deck 5, and 4 bottom of valve body is air inlet 6, on the valve body of 6 side of air inlet
It is provided with the first stomata 7, valve deck 5 is installed at the top of valve body 4,5 center of valve deck is provided with the second stomata 8, and 5 top right side of valve deck passes through company
Fitting 2 is fixedly connected with pneumatic control valve 3, and pneumatic control valve 3 is by application valve body 9, valve plate 10, valve rod 11, cylinder 12 and hood
13 form, and are provided with valve plate slot 14 in the middle part of application valve body 9, and valve plate 10 is equipped in valve plate slot 14, connects valve rod 11 on the right side of valve plate 10,
Cylinder 12 is pneumatically connected on the right side of valve rod 11,14 vertical direction of valve plate slot is communicated with air inlet 15 and venthole 16, and air inlet 15 is logical
It crosses admission line 17 and connects the first stomata 7, venthole 16 connects the second stomata 8,16 inside three of venthole by outlet pipe 18
Lead to and be connected to exhaust pipe 19,19 middle part of exhaust pipe is truncated by valve plate slot 14, and bottom is connected to hood 13.
Further, corresponding on the inside of air inlet 6 that flap 20 is installed, bullet is cased between 20 top of flap and 5 bottom of valve deck
Spring 21, middle part are cased with O-ring seals 22, and bottom surface is hemispherical.
