It states the exit passageway set in flange and is connected on the right side of inner cavity, bushing upper head covers the spool of bowl-type, the spool and edge
It puts on and sets sealing ring between end face, the connector in the hole and valve rod lower end of spool is fixed, and the excircle of spool is interior with guide sleeve one
Hole is connected, and the connector upper end of the valve rod sets locating piece, and the upper surface of the valve seat sets nut, the upper guide sleeve
External screw thread is stretched upwards from valve base cavity to be spirally connected with nut, and the externally threaded lower end of upper guide sleeve sets locating piece one, the spring pocket
After entering valve rod, the hole of spring bottom is socketed on the step of locating piece, and the hole of spring upper end is socketed on the step of locating piece one
Afterwards, valve seat is installed in the upper end of valve body, and valve deck is mounted on valve seat upper end valve seat upper end closed.
The step clamp-mounting type of the guide sleeve one is fixed between the counterbore among valve body upper surface and valve seat lower face.
The beneficial effects of the utility model：Medium access way is mutually perpendicular to set by the utility model, can be effective
Meet pressure pipeline, container, boiler system labyrinth safety, effectively avoid when arranging outside high pressure gas to outside
The security risk on periphery, can also be recovered to the high pressure gas of outer row another space utilization, under safe condition, internal gas
To spool recoil pressure holding function, the stability of spool when greatly improving normal condition, and it is whole by upper guide sleeve threaded adjusting
Constant-pressure reaches the mechanical performance of effectively safety valve, safety and practicability are high, use the longevity to efficiently control discharge capacity
Life length.
