Abstract
The invention relates to an adjustable and replaceable reversible fluid converter, which belongs to the technical field of nuclear energy. During product development experiments of the existing reversible fluid converter, a great number of RFDs (reverse fluidic devices) with different nozzle diameters and different nozzle intervals are required to be machined. The adjustable and replaceable reversible fluid converter provided by the invention comprises a nozzle connecting element, a nozzle, a connecting pipe and a cavity body, wherein the nozzle connecting element is in threaded connection with the cavity body and the nozzle; and the connecting pipe and the cavity body are welded into a component. By virtue of the adjustable and replaceable reversible fluid converter, the intervals of the nozzles can be adjusted conveniently and rapidly, and nozzles with different diameters can be replaced under the condition of not machining the RFDs again.
Description
Technical field
The invention belongs to the nuclear energy technology field, relate to a kind of reversible fluid switch (hereinafter to be referred as RFD) in the reversible fluid pump system (Reveres Fluidic Device is hereinafter to be referred as the RFD system) in the research of nuclear energy development technique, be specifically related to a kind of reversible fluid switch of adjustable changeable.
Background technique
Reversible fluid pump system (Reveres Fluidic Device is hereinafter to be referred as the RFD system) is applied to the conveying of radioactive fluid in the reprocessing as a kind of fluid delivery system of freedom from repairs.
As shown in Figure 1, RFD System Working Principle and process are as follows: device starts instantaneous, vacuum ejector is air-breathing, in the transducing cylinder, produce negative-pressure gas, liquid-vaqor interface rises, and RFD sucks feed liquid from feeder groove and enters the accumulation of energy of transducing cylinder, at this moment, system exports without flow, and the gas that vacuum ejector is sent enters ventilation system through outlet pipe; After liquid level arrives setting value, close vacuum ejector, open simultaneously the compression injection device, system enters to press and rushes the stage, and the compression injection device is to transducing cylinder input barotropic gas, and liquid-vaqor interface descends gradually, this moment, transducing cylinder downstream formed positive press liquid, and directly entered discharge nozzle via RFD and go out stream; After transducing cylinder liquid level reaches setting value, the closes compression sparger, transducing cylinder barotropic gas begins exhaust and enters exhaust phase, RFD is owing to running out of steam, outflow reduces gradually until the whole system flow is zero, open vacuum ejector enter the next back suction accumulation of energy stage this moment, and system goes round and begins again according to this and forms intermittence and go out stream.
RFD is as the parts of reversible fluid pump system key, and the hydrodynamic structure parameter of RFD is to whole system conveying capacity important, and wherein RFD orifice size and injector spacing are particularly important.As shown in Figure 2, structure nozzle and the mouth spacing of existing RFD can not be regulated, and orifice size is also fixed, so in the product development test, need the RFD of a large amount of different spray nozzles diameters of processing, different spray nozzles spacing.
Summary of the invention
For the defective that exists in the prior art, the object of the present invention is to provide the reversible fluid switch of the adjustable changeable of a kind of RFD of being applicable to fluid delivery system experimental study, this reversible fluid switch can be regulated injector spacing quickly and easily, and can be in the situation that again do not process the nozzle that RFD changes different-diameter, thereby reduced the workload of test, greatly save the man power and material, improved efficiency of research and development, shortened the R﹠D cycle.
For reaching above purpose, the technical solution used in the present invention is:
A kind of reversible fluid switch of adjustable changeable, this device comprises nozzle link, nozzle, adapter, cavity, wherein, between described nozzle link and the cavity with being threaded; Between nozzle link and the nozzle with being threaded; Adopt Type of Welding between adapter and the cavity, make both become parts.
Further, the end at the nozzle link is provided with clamp type quick connector.
Further, nozzle link (3) adopts Type of Welding to be connected with clamp type quick connector (1).
Further, be provided with locking nut (2) at nozzle link (3).
Further, be threaded connection between locking nut (2) and the nozzle link (3).
Further, between nozzle link and cavity, be provided with the O RunddichtringO.
Further, change injector spacing by the locking nut of adjusting the RFD two ends.
Further, described nozzle can be dismantled and change.
Effect of the present invention is: adopt device of the present invention, greatly reduced the amount of finish of RFD, reduced the frequency of component dismounting, replacing, but the adjusting of canbe used on line injector spacing, develop the optimum nozzle spacing, reduced the workload of test, greatly saved the man power and material, improve efficiency of research and development, shortened the R﹠D cycle.
