Description
Technical field
The present invention relates to valve technology fields, more particularly to a kind of hydraulic hybrid accumulator shut-off valve.
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.Accumulator is hydraulic air
One of dynamic system energy savings device.It is that compression energy or position can store that it, which is in due course the energy conversion in system,
Get up, when system needs, and compression energy or position can be changed into the energy such as hydraulic or air pressure and released, mend supply system again
System.When system instantaneous pressure increases, the energy of this part is can be absorbed in it, to guarantee that whole system pressure is normal.Currently, with
