Description
Technical field
The utility model relates to valve related fields, specially a kind of dust guard of shut-off valve peculiar to vessel.
Background technique
Shut-off valve is also known as pipe valve valve, belongs to forced seal formula valve, so when valve is closed, it is necessary to apply to flap and press
Power is not leaked with forced seal face.When medium is by entering valve below flap, the resistance overcome required for operating force, is valve
The frictional force of bar and filler 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 valve rod
Diameter it is big, the failure of valve rod bending otherwise can occur.It is divided into three kinds by connection type: flanged joint, screwed connection, welding
Connection.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 in medium pressure
Under power effect, the power of closing valve is small, and the power of valve opening door is big, and the diameter of valve rod can be reduced correspondingly.Meanwhile it being acted in medium
Under, the valve of this form is also relatively tight.China's valve " three change give " once provides, the flow direction of shut-off valve, without exception using from upper and
Under.When shut-off valve is opened, the Lift of flap, flow has reached maximum when being the 25%~30% of nominal diameter, indicates valve
Door has reached fully open position.So the fully open position of shut-off valve, should be determined by the stroke of flap.The opening and closing element of shut-off valve is stopper
Flap, sealing is for linear motion along the center line of valve seat in plane or the extra large conical surface, flap above.The forms of motion of valve rod is (logical
With title: dark bar), also have lifting rotation rod-type can be used for controlling empty gas and water, steam, various corrosive medias, mud, oil product,
The flowing of the various types fluid such as liquid metal and radiating medium.Therefore, such shut-off valve valve that shuts off is very suitable
Cooperation is used for cutting or adjusting and throttling.Since to open or close stroke relatively short for the valve rod of such valve, and have
Very reliable cutting function, and due to the stroke direct proportionality of the variation of valve seat port and flap, is very suitable for pair
The adjusting of flow.
Shut-off valve peculiar to vessel is off a member in valve big family.It is primary to be applied to above shipbuilding.In the corruption of resistant to sea water
There is the significant achievement of comparison in corrosion.The shut-off valve of material with is slightly different.Mainly there are stainless steel shut-off valve and brass to cut
Only valve etc..Once shut-off valve leakproofness peculiar to vessel is not tight, it will cause dust to enter the inside of valve, it will to largely effect on valve
Service life.
