Description
Technical field
The present invention relates to valve technology field more particularly to it is a kind of can be with the shut-off valve of Fast Installation.
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.
Shut-off valve in the prior art is mainly installed by the way of flanged joint with water pipe, such mode install and
All screw thread and nut must be mounted and dismounted successively simultaneously when dismounting, it is extremely time-consuming and laborious, it is needed for this problem
It is improved.
