Abstract
The utility model discloses a glass nozzle without crystallization, wherein a water bowl is arranged on the front portion of an air faucet, the middle portion of the air faucet is connected with a water nozzle through a supporting frame, the inner diameter of the tail portion of the water nozzle is a first cylindrical passage, a diffused bellmouthing is arranged on the end portion of the water nozzle, the angle beta which is formed by the diffused bellmouthing is 105 to 115 degrees, the inner diameter of the front end of the air faucet is a second cylindrical passage, and the angle alpha which is formed by the air faucet and the water nozzle is 86 to 90 degrees. The glass nozzle is arranged and used on a salt mist spraying device and satisfies the standards of an American MIL-STD-810F.509.4 (2000) edition. The glass nozzle is suitable for demands of the salt mist settlement of 1 to 3m L/80cm[2].h, the salt mist settlement is bigger than 2.0m L, the relative humidity of the region of a nozzle head approaches saturation, the glass nozzle can not crystallize after being used for long time, and the repeatability of the salt mist settlement is good.
Description
Technical field
The utility model belongs to the climatic environment experimental facilities, relates in particular to speciogenesis salt fog injection nozzle.
Background technology
The device that salt fog forms is necessary for the anti-smog corrosivity of some equipment of detection or machine.
The glass atomizer that existing salt fog forms in the device is extensive use of in environmental experiment equipment industry, but its salt fog settling amount is only at 1～2mL/80cm
2.h, can not satisfy U.S. MIL-STD-810F.509.4 (2000) release criteria.Simultaneously, existing glass atomizer is easily separated out crystallization when long-term the use, and the quality of the salt fog settling amount of generation is descended.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of long-term use to be difficult for separating out crystallization, the no glass ceramics nozzle of salt fog settling amount favorable reproducibility.
The technical solution of the utility model is summarized as follows:
A kind of no glass ceramics nozzle, the front portion of valve is provided with the water bowl, the middle part of described valve is connected with water nozzle by support, described water nozzle afterbody internal diameter is first cylindrical channel, the diameter of described first cylindrical channel is 0.9～1.4mm, the length of described first cylindrical channel is 0.9～2mm, described water nozzle end is provided with the diffusion hydraucone, the formed β of described diffusion hydraucone angle is 105～115 °, the internal diameter of described valve front end is second cylindrical channel, the diameter of described second cylindrical channel is 0.65～1.1mm, and the length of described second cylindrical channel is 2.5～6mm, and described valve and the formed α of described water nozzle angle are 86～90 °.
The volume of described water bowl is 4～8mL.
Beneficial effect: a kind of no glass ceramics nozzle of the present utility model is arranged on the salt fog spraying equipment and uses, and can satisfy U.S. MIL-STD-810F.509.4 (2000) release criteria.Be fit to salt fog settling amount 1～3mL/80cm
2.h requirement, salt fog settling amount〉2.0mL, head of nozzle zone relative humidity is near saturated, use for a long time non-crystallizable, salt fog settling amount favorable reproducibility.
