Abstract
The utility model discloses a spraying device for an adjustable salt spray testing box, which comprises an air pipe and a salt spray pipe, wherein the air pipe and the salt spray pipe are vertically arranged, the air pipe and the salt spray pipe are respectively fixed on the horizontal surface and the vertical surface of a mounting bracket, a salt spray nozzle is arranged at the outlet end of the salt spray pipe, the salt spray nozzle is fixed in the salt spray pipe through a pressure cap nut and a gasket, the salt spray nozzle adopts a polyfluortetraethylene plastic pipe, and the utility model adopts an adjustable assembly, improves the abuse of difficult regulation caused by that the spray amount and the spray drop size of original salt spray equipment only can be controlled through pressure regulation, and conveniently realizes the regulation of the spray amount and the spray drop size through replacing the salt spray nozzles with different inside diameters; and in addition, the utility model discards a glass material adopted by the traditional salt spray nozzle and uses the polyfluortetraethylene plastic pipe, thereby a frequently occurring phenomenon of nozzle blockage in testing is radically solved.
Description
Technical field:
The utility model relates to the parts of salt spray test chamber, particularly a kind of salt spray test chamber sprayer unit.
Background technology:
Produce the nozzle of salt fog owing in hypersaline environment atmosphere, can not use ordinary metallic material in the salt spray test equipment, usually glass material is made, but hydrolysis can take place in common silicate glass under the long term of salt solution, the alkaline matter that polarization is stronger, easily make the sodium chloride enrichment in the salt solution, particularly in the nozzle edge, because of the effect moisture of negative pressure evaporates rapidly, make the concentration increase of salting liquid be tending towards supersaturation, cause the sodium chloride crystallization in use for some time, finally cause spout to stop up, make testing equipment can not be under the standard code state operate as normal.Salt atomizing nozzle and salt fog pipe on the existing salt spray test chamber are an integral body, and internal diameter is fixed, and is difficult to regulate spray amount and droplet size.
Summary of the invention:
The purpose of this utility model is to provide a kind of salt spray test chamber sprayer unit, solves in traditional salt fog testing equipment spray amount, droplet size and is difficult to regulate and the susceptible to plugging problem of spout.
The purpose of this utility model takes following technical scheme to be achieved:
The salt spray test chamber sprayer unit, comprise vertically disposed air hose and salt fog pipe, air hose and salt fog pipe are separately fixed at the horizontal plane and the vertical plane of mounting bracket, described air hose and salt fog pipe are and have externally threaded two siphunculus, air port is met with the salt fog spout is vertical, it is characterized in that the salt fog pipe port of export establishes a salt atomizing nozzle, the salt atomizing nozzle is fixed in the salt fog pipe.
The further technical scheme of the utility model is that described salt atomizing nozzle is to be fixed in the salt fog pipe by the pressure cap nuts and washers.
The polytetrafluoroethylene (PTFE) that described salt atomizing nozzle is internal diameter 1.0～2.0mm is moulded pipe.
By technique scheme as seen, the utility model adopts adjustable component, improved former salt fog equipment and can only regulate control spray amount and the big or small drawback that causes adjusting to be difficult for of droplet, can realize regulating spray amount and droplet size easily by the salt atomizing nozzle of changing different inner diameters by pressure; In addition, the utility model has been abandoned the glass material of traditional salt atomizing nozzle employing and has been used polytetrafluoroethylene (PTFE) instead and mould pipe, has fundamentally solved the spray nozzle clogging phenomenon that often occurs in the test.
Description of drawings:
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is described in further detail:
As shown in drawings, air hose 2 and salt fog pipe 3 are for having externally threaded two siphunculus, air hose 2 and salt fog pipe 3 are respectively with the horizontal plane 11 of mounting bracket 1 with the screw on the vertical plane 12 cooperates and by adjusting nut 4,5 is fixing, salt fog pipe 3 ports of export are established a salt atomizing nozzle 6, salt atomizing nozzle 6 is to be fixed in the salt fog pipe 3 by pressure cap nut 7 and silicone gasket 8, pressure cap nut 7 cooperates with the external screw thread screw thread of salt fog pipe 3 ports of export, the spout 61 of salt atomizing nozzle 6 is positioned at the top of air port 21 and meets but do not contact with air port 21 is vertical, and salt atomizing nozzle 6 is moulded pipe for the polytetrafluoroethylene (PTFE) of internal diameter 1.0～2.0mm.Tune salt fog pipe 3 and can regulate salt atomizing nozzle 6 move left and right, tuning air hose 2 can regulate air port 21 and move up and down, mounting bracket 1 is located on the salt fog baffle plate in the salt fog equipment, air hose 2 and salt fog pipe 3 connect air hose and salt water tube hose respectively, under the operating air pressure of regulation, pass through to regulate the distance of air and salt atomizing nozzle, measure salt fog settling amount and distribution situation, secured adjusted nut 4,5 behind the searching optimum working state.
