Working principle of spray valve

In modern industry, agriculture and life, the spray valve, as a key equipment, plays a pivotal role. However, do you know how the spray valve works? This article will unveil the mystery of this device for you.

1、 What is a spray valve

Spray valve, called spray or atomizer, is a device used to convert liquid into mist. It mainly consists of nozzles, valves, and driving devices. The nozzle is the core component of the spray valve, which can disperse the liquid into tiny particles to form a fog, so as to better apply to specific fields.

2、 Working principle

The working principle of spray valve is based on two main processes: liquid atomization and droplet transmission.

1. Atomization of liquids

When a liquid passes through a nozzle, it is excited by high pressure or other forms of energy. Under the action of the nozzle, the liquid flow rate increases sharply and is subjected to severe shear forces. This high-speed flow and shear force disrupt the surface tension of the liquid, dispersing it into tiny droplets. The size and distribution density of these droplets depend on the design of the nozzle and the properties of the liquid.

2. Transport of mist droplets

After liquid atomization, droplets will be transported to the target surface through airflow or inertial motion. During this process, fog droplets may be affected by environmental factors such as air resistance, humidity, and temperature, leading to their evolution and dispersion during transportation.

3、 Application field

1. Industrial applications

In industrial production, spray valves are used for spraying, cooling, humidification, sand blasting, etc. In the spraying process, the spray valve can transform the liquid coating into fine particles, form a uniform coating, and improve the coating quality and efficiency.

2. Agricultural applications

Agricultural spray system is widely used in crop spraying and fertilization. Through the spray valve, the pesticide and fertilizer can be transformed into fog, which can achieve accurate application and reduce waste and environmental pollution.

3. Medical applications

The spray valve is used for drug atomization in the medical field. For example, atomizers can convert liquid drugs into mist and enter the lungs through the patient's breathing, used to treat respiratory diseases.

In a word, as a result of modern science and technology, spray valves play an important role in various fields. Through the working principle of the spray valve, we can transform the liquid into small droplets to achieve more efficient and accurate application. However, the development of spray valves is still advancing, bringing more opportunities and challenges. It is believed that in the future, with the further development of science and technology, spray valves will show great potential and value in more fields.
