Description
Technical field
The utility model belongs to the liquid level limit valve knot of liquid level limit valve technical field more particularly to a kind of cylinder for liquefied gas
Structure.
Background technique
LPG valve belongs to forced seal formula valve, so when valve is closed, it is necessary to apply pressure to flap, with strong
Sealing surface processed does not leak.When medium is by entering valve chamber below flap, the resistance overcome required for operating force, is valve rod and filler
Frictional force and the thrust as caused by the pressure of medium, the power of closing valve is bigger than the power of valve opening door, so the diameter of valve rod is wanted
Greatly, the failure of valve rod bending otherwise can occur.In recent years, after the appearance of the valve of self-sealing, the medium flow direction of shut-off valve just changes
By entering valve chamber above flap, at this moment under pressure medium effect, the power of closing valve is small, and the power of valve opening door is big, valve rod it is straight
Diameter can be reduced correspondingly.Meanwhile under medium effect, the valve of this form is also relatively tight.China's valve " three changes are given " was once
Regulation, the flow direction of shut-off valve, without exception using from top to bottom, when liquefied gas shut-off valve is opened, the Lift of flap is that nominal is straight
Diameter 25%~30% when, flow has reached maximum, indicates that valve has reached fully open position.So the fully open position of shut-off valve, is answered
It is determined by the stroke of flap.
