Description
Technical field
The present invention relates to shut-off valve technical field more particularly to a kind of high sealing performance shut-off valves.
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
Fully open position is reached.So the fully open position of shut-off valve, should be determined by the stroke of flap.But present shut-off valve leakproofness
Also not enough, during use, liquid leakage is had, and then affect the use of people, we have proposed one kind thus
