Abstract

The invention discloses a replaceable spray nozzle connecting assembly. The replaceable spray nozzle connecting assembly comprises an integrated block, an overflow valve and a spray nozzle support, wherein the integrated block is internally provided with a two-end-through flow path; one end of the integrated block is used for being connected with a pipeline joint, and the other end of the integrated block is used for being connected with another pipeline joint; the overflow valve is mounted on the integrated block; a spray nozzle support containing part communicating with the flow path from the wall face of the integrated block is formed in the middle of the integrated block; and the spray nozzle support is arranged in the spray nozzle support containing part and used for containing a spray nozzle. Compared with the prior art, the replaceable spray nozzle connecting assembly is simple in structure, the spray nozzle structure is simplified especially, series spray nozzles with differentopening diameters can be machined more rapidly, conveniently and economically.

Description

technical field [0001] The invention relates to the technical field of pipeline connection, in particular to a replaceable nozzle connection assembly. Background technique [0002] In the endurance test of the engine accessory casing laboratory, the fuel pump is used to load the accessory casing, and the flow and pressure of the fuel accessories are changed by changing the nozzle hole diameter in the outlet pipeline of the fuel pump to achieve the purpose of changing the loading load. In the prior art, in order to adjust the load of the fuel pump in the test, it is often necessary to replace nozzles with different apertures, but the current nozzle installation structure makes it difficult to replace the nozzles (in the test, the throttling part of the fuel system pipeline needs to work stably for a long time, and can Only the nozzle structure can be used to accurately evaluate the working conditions of the system. If the adjustable throttle valve is used, the flow area of ​​...
