Description
Technical Field
The utility model relates to a nozzle throttling arrangement technical field, concretely relates to anti-recoil major diameter nozzle that drops.
Background
The nozzle orifice is in communication with a conduit, and the orifice is typically provided with a flow restriction assembly therein. As the pipe-filled fluid flows through the nozzle restriction, the flow stream will form a partial constriction at the restriction, causing an increase in flow velocity and a decrease in static pressure, creating a pressure differential across the restriction. The nozzle throttling device measures the flow of the fluid by measuring the pressure difference between the front and the back of the throttling element, and is widely applied to process control and measurement in the fields of nuclear power plants, petroleum, chemical engineering, metallurgy, electric power, heat supply, water supply and the like.
Now, the authorization notice number: CN207923207U, a core-pressure level long neck nozzle device is got to footpath distance, including coaxial coupling's upstream straight tube section and low reaches straight tube section, the junction of upstream straight tube section and low reaches straight tube section is provided with the nozzle, the nozzle is including pressing from both sides the go-between of placing upstream straight tube section and low reaches straight tube section and stretching into the extension ring in the low reaches straight tube section, extension ring and go-between fixed connection, the upstream straight tube section is provided with first thickening portion on being close to the lateral wall of the one end of go-between.
After practical production and use, the long-diameter nozzle has the following problems: after the nozzle works in a pipeline for a long time, under certain extreme conditions, the inlet end of the nozzle suddenly reduces the pressure seriously and even loses the pressure (generally, a feed pump at the upstream of the nozzle is stopped or a pump outlet valve is quickly closed), the condition that medium in the pipeline reversely impacts the nozzle can occur, huge pressure difference and the self weight of fluid in the pipeline are all applied to a nozzle throttling piece, the conventional long-diameter nozzle throttling piece is only fixed through a pin, and during forward flow, the huge pressure difference and the weight are applied to a support ring at the back of the nozzle (the support ring is welded with the inner wall of the pipeline), so the pin is auxiliary pressure bearing, but when a backflushing condition occurs, the pin is only used for bearing pressure, and the phenomenon that the nozzle falls off due to the fact that the pin cannot bear the reverse high pressure and the huge weight is easily caused.
In conclusion, in order to ensure the safe operation of the equipment, the anti-recoil and anti-falling long-diameter nozzle is designed.
SUMMERY OF THE UTILITY MODEL
The utility model provides a long footpath nozzle that prevents recoil and drops in order to overcome foretell not enough.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
