Pressure-adjustable type pressure-stabilizing nozzle

Abstract

The invention discloses a pressure-adjustable type pressure-stabilizing nozzle, and relates to the technical field of nozzles. The pressure-adjustable type pressure-stabilizing nozzle comprises a shell, a liquid supply joint and a nozzle, wherein the liquid supply joint and the nozzle are formed by the shell; the shell also can form a rectifying cavity which communicates with the nozzle and a liquid feeding cavity which communicates with the liquid supply joint; a diameter-varied pipe section with a contracted middle part as well as expanded front and rear parts, which is formed by the shell,is arranged between the liquid feeding cavity and the rectifying cavity which is formed in the front end of the shell; the shell can form a separate pressure regulating cavity at the rear of the liquid feeding cavity; the nozzle also comprises a shell which penetrates through the pressure regulating cavity and the liquid feeding cavity and penetrates between the pressure regulating cavity and theliquid feeding cavity, and finally extends to a control rod which is positioned at an intercrossing part of the diameter-varied pipe section and the rectifying cavity; and the control rod can be movedback and forth in the shell, and a pressure regulation process and a pressure stabilizing process of the nozzle can be realized through back-and-forth movement of the control rod. The nozzle disclosed by the invention has a function of automatically and accurately regulating injection pressure ratio, and has the advantages that the stability and adjustability of the pressure of a flow field in the nozzle can be ensured, and the stability of injection flow of the nozzle is improved; and moreover, the pressure-adjustable type pressure-stabilizing nozzle also has an atomizing enhancement function, so that the quality of jet flow works is improved.

Description

technical field [0001] The invention relates to the technical field of nozzle manufacturing, in particular to a pressure-adjustable pressure-stabilizing nozzle. Background technique [0002] Nozzles can be roughly divided into spray nozzles, fuel nozzles, sandblasting nozzles, watering nozzles, etc. according to their functions. Usually, the pressure of the nozzles comes from the pressure of the high-pressure liquid in the pipeline connecting the nozzles, so when the unstable high-pressure liquid enters the nozzle When the nozzle itself cannot be self-regulated, this will cause the instability and unbalance of the liquid flow rate. When the unstable high-pressure liquid is sent into the nozzle, there will be a significant change in pressure, which will affect the quality of the jet flow of the nozzle and the ejection flow rate. Extremely unstable. [0003] In order to solve this problem, it is usually possible to improve the working efficiency of the jet nozzle by adjusting...
