Technical field
The utility model is a kind of high-pressure stop valve, belongs to hardware engineering device technique field.
Background technology
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 below flap by entering valve, the resistance overcome required for operating force, is valve
The frictional force of bar and filler and thrust caused by the pressure by 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 sealss, the medium flow direction of shut-off valve just changes by entering valve chamber above flap, at this moment in medium pressure
Under force 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, flows have reached maximum when being the 25%~30% of nominal diameter, indicate valve
Door has reached fully open position.So the fully open position of shut-off valve, should be determined, but existing shut-off valve is being used by the stroke of flap
When, when closing, since internal pressure is larger, and internal seal is bad, leads to often have the case where leak.
