Problems solved by technology

[0004] (2) When the pressure in the liquid delivery pipeline in the liquid spraying device is constant, the nozzle can only spray at a constant flow rate
[0005] (3) At present, the spraying effect of the nozzle still has a large gap with the ideal requirements in many aspects such as the uniformity after spraying and the coverage area.

Embodiment Construction

[0028] A drip-proof and throttling nozzle device of the present invention and its application method in conjunction with its application in train antifreeze spraying devices will be described in further detail below in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, a drip-proof and throttling nozzle device of the present invention is composed of a gap diaphragm 1, a nozzle top core 2, a nozzle bottom core 3, a slotted pan head screw 4 and a nozzle cover 5. The gap diaphragm is placed in the circular groove on the upper end surface of the nozzle top core 2; the outer part of the nozzle top core 2 has metric threads on the two cylindrical surfaces with different radii, and the metric thread on the cylindrical surface with the smaller radius is used For the connection between the nozzle top core 2 and the antifreeze liquid delivery pipeline, the metric thread on the surface of the cylinder with a larger radius is used for the connection between t...

Abstract

The invention relates to a drip-proof throttling nozzle device and a usage thereof, which belong to the field of mechanic design, in particular to a drip-proof throttling nozzle device which effectively prevents residual liquid flows down in a large amount after spraying liquid on the nozzle and adjusts the flow of liquid and a technical scheme of the usage. The drip-proof throttling nozzle device consists of a gap membrane, a nozzle top core, a nozzle bottom core, a slotted pan head screw and a nozzle outer cover. In the invention, the nozzle is provided with a gap membrane assembly and a nozzle bottom core assembly and the two and other assemblies of the nozzle and related assembling relationship are arranged so that drip-proofing and adjustment of flow are realized when the nozzle sprays, deficiency that the residual liquid flows down in a large amount after spraying liquid on the nozzle is overcome and the flow of liquid flowing through is controlled by adjusting the nozzle. And the opening form of the nozzle is designed so that the liquid sprayed is in form of a fan to improve the spraying uniformity and covering area.

Description

technical field [0001] The invention relates to an anti-drip and throttling nozzle device and its use method, belonging to the field of mechanical design, and in particular to an anti-dripping device that effectively prevents a large amount of residual liquid from flowing down after the nozzle sprays liquid and realizes that the nozzle can adjust the flow of liquid passing through it. A dripping and throttling nozzle device and a technical proposal of a using method thereof. Background technique [0002] As a very important part of the liquid spraying device, the nozzle is widely used in many fields such as mining, metallurgy, chemical industry, automobile, electronics, agriculture, papermaking, printing, environmental protection, power generation, water treatment and precision machinery. In modern production practice, the requirements for the use of nozzles are getting higher and higher. It is not only required to shorten the follow-up cleaning tasks of workers after sprayi...
