Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by specific embodiment, following examples are to retouch
The property stated, be not limited, it is impossible to limit protection domain of the present utility model with this.
A kind of high water head nozzle type pressure regulation valve cone grid combine energy dissipator, installed in the water outlet of nozzle type pressure regulator valve 1,
Concrete structure is referring to shown in accompanying drawing 1, including Taper Pipe 3, internal diversion cone 5, annular gusset 6 and collecting pipe 8, is adjusted in nozzle type
Pressure regulation valve nozzle 2 is coaxially installed with the middle part of the outlet of pressure valve 1, it is coaxial in the outlet of the nozzle type pressure regulator valve of pressure regulation valve nozzle periphery
The upper end of a Taper Pipe 3 is fixed with, the central angle of the Taper Pipe is 30 °, be coaxially fixedly mounted with the lower end of Taper Pipe/collecting pipe is formed with, the remittance
Flow tube is cylinder cylinder structure, and the inner coaxial tube that confluxes below pressure regulation valve nozzle is fixed with an internal diversion cone 5, inside this
The drift angle of guiding cone is coaxial with pressure regulation valve nozzle upwards, and the central angle of internal diversion cone is 30 °, reduces what is produced during draining
Vibrations；
3 times of a diameter of upper end diameter of the lower end of Taper Pipe, flow velocity is reduced to 1/9, and 1/ when kinetic energy is only jet expansion
81, the diameter of collecting pipe and the water inlet equal diameter of nozzle type pressure regulator valve do not influence former flow rate of pipelines to fully ensure that.
The inside pipe wall that confluxes of internal diversion cone lower end is fixed with annular gusset 6, and the structure of the annular gusset is referring to accompanying drawing 2
