Technical field
The utility model relates to Gas Pressure Regulating Equipment technical fields, more particularly to a kind of breathing balanced type pressure regulation
Device.
Background technique
Gas pressure regulator, governor is commonly called as pressure reducing valve, is to keep outlet gas and changing the gas flow through regulating valve automatically
The equipment of authorized pressure is generally divided into direct acting type and two kinds of indirect acting type.Direct acting type pressure regulator is by measuring cell
(film), transmission parts (valve rod) and regulating mechanism (valve) composition, gas consumption behind outlet increases or inlet pressure reduces
When, outlet pressure just declines, and at this moment makes to act on the power on the downside of film less than (or the bullet of pouring weight on film by the pressure that connecting pipe reflects
Spring) power, film decline, flap moves down also with valve rod, opens valve greatly, and gas flow increase, outlet pressure is restored to original
Come given numerical value, conversely, valve turns down, and flow-reduction still makes when the gas consumption reduction or inlet pressure behind outlet increase
Outlet pressure is restored, and the weight of exit pressure levels available adjustment pouring weight or spring force give.
Existing gas pressure regulator, governor can all be provided with the balance venthole communicated with atmosphere in pressure regulating member, make interiors of products
Pressure and atmospheric pressure keep balancing, but conventional balanced venthole is all using through type, and this structure makes interiors of products
