Description
Technical Field
The invention relates to the technical field of water treatment industry and machining, in particular to a self-locking device of a threaded connection pressure atomizing nozzle.
Background
The nozzle is a key part in various spraying, atomizing, oil spraying, sand blasting and other equipment, even a main part, and has wide application in many places of production and life. The mechanical pressure type atomizing nozzle occupies an important proportion therein. The pressure type atomizing nozzle provides kinetic energy for fluid by utilizing power equipment such as a pump or a compressor and the like, the kinetic energy of the fluid is converted into potential energy before the outlet of the nozzle, high potential energy is sprayed out of the nozzle through a spinning disk at the position of the nozzle or a spraying structure at the outlet of the nozzle, and the fluid is dispersed and crushed to generate an atomizing effect.
The connection of the nozzle and the pipeline or the device has different modes according to different use occasions, different fluids, different pipe diameters, different pressure grades, different materials and the like. Common connection means are flange connection, screw connection, snap connection, welding, winding connection, etc. Each connection has its own characteristics and is suitable for different working conditions.
The pressure atomizing nozzle connected with the thread often has the condition that the spray head falls off in the operation process, and once the spray head falls off, the local or overall atomizing effect is possibly deteriorated, and even the production is influenced.
The reason that threaded connection nozzle drops is many, get rid of because of the screw thread mismatch, the screw thread machining precision is not enough, the material chooses for use outside unreasonable factors such as, the screw fastening factor that becomes invalid still has 1, the characteristics of nozzle material, like materials such as carborundum nozzle, plastics nozzle, ceramic nozzle, has the multiple advantage that metal class nozzle does not possess, but on the processing of screw thread, does not possess the characteristics that metal is workable, the degree of agreeing with is good, the threaded connection's of this type of material nozzle often drops easily. 2. The expansion amount at the use temperature is different, and many nozzles are used in a high-temperature or low-temperature environment, but the installation condition of the nozzles and the pipeline is that the different expansion amounts are generated after the temperature changes due to the different shapes and materials of the nozzles and the pipeline at normal temperature, and the contact surface gaps of the internal threads and the external threads after the expansion change. The enlarged pores reduce the effect of the frictional torque, and the nozzle is easily detached. 3. The vibration of the nozzles or the pipelines is caused by the fact that the kinetic energy and potential energy of fluid are converted widely in the pressure atomization process, and the nozzles are often arranged in a plurality of groups, so that the connecting pipelines are long. Therefore, common atomization systems have vibration of different degrees, the vibration enables the threaded nozzle to be more easily loosened, and the nozzle is promoted to fall off under the action of outward pressure of fluid.
In order to solve the problem of falling, people adopt various correction methods through experience summary of long-term use, wherein the correction methods comprise adding thread fastening glue, adding a winding belt after thread connection and the like. Other connection means such as flange connection, winding connection of female interface, etc. may also be used by changing the threaded connection. Sometimes, the change of the alternative connection mode of the nozzle still does not solve the essential problem, but can bring many negative effects to the system operation
An effective solution to the problems in the related art has not been proposed yet.
