[0015] Compared with the prior art, the present invention provides a chamfering device for pressure reducing valve production, which has the following beneficial effects:

[0017] 2. A chamfering device for producing a pressure reducing valve has the ability to exhaust air by arranging a second air pump and utilizing the air guide pipe and the air guide plate in the bottom box, so that the collecting plate on the top of the bottom box can aerate the liquid in the bottom box, so that the liquid in the bottom box can splash.
