Description

A kind of shut-off valve self-lock switch peculiar to vessel

Technical field

The utility model relates to valve related fields, specially a kind of shut-off valve self-lock switch 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..The self-locking structure of existing shut-off valve peculiar to vessel easily frays button, and with influencing performance after long, and structure is complicated, production It is at high cost, it assembles relatively difficult.
