Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
The invention provides a kind of super-pressure balance type pneumatic break valve as depicted in figs. 1 and 2, including hex nut 1,
First O-ring 2, the second O-ring 3, sealing ring 4, gland 5, the first back-up ring 6, the second back-up ring 7, the 3rd the 8, first general plug envelope of O-ring
9th, piston 10, upper blanking cover 11, piston rod 12, valve body 13, the 4th O-ring 14, valve rod assembly 15, pad 16, valve port 17, second are general
Plug envelope 18, lower plug cover 19 and hexagon socket cap head screw 20, the lower end of the upper blanking cover 11 are provided with piston 10, the piston 10
Lower end is connected with piston rod 12, and the junction between the piston 10 and piston rod 12 is provided with sealing ring 4, the upper blanking cover 11 with
It is connected and is structure as a whole by hexagon socket cap head screw 20 and hex nut 1 between the valve body 13 of its lower end, under described
The upper end of blanking cover 19 is provided with valve rod assembly 15, and the middle part lower end of the valve rod assembly 15 is provided with valve port 17, the valve port 17 it is upper
End is provided with pad 16, and the contact site between the bottom of the valve rod assembly 15 and lower plug cover 19 is provided with the second general plug envelope 18, described
