I. Introduction. As an important control element, high-pressure solenoid valve has a wide range of applications in the field of industrial automation. It has the advantages of simple structure, convenient control and high reliability, so it is favored by engineers and technicians. However, in the face of a dazzling array of high-pressure solenoid valve products on the market, how to choose the product that suits your needs has become a question worth pondering. This article will introduce in detail the working principle, selection parameters, brand selection and other aspects of high-pressure solenoid valves to help readers better understand and choose high-pressure solenoid valves.
Second, the working principle of high-pressure solenoid valve.
The high-pressure solenoid valve is a kind of valve that uses electromagnetic force to control the on-off of the medium, and its working principle mainly includes four parts: electromagnet, valve core, valve seat and medium. When the electromagnet is energized, the generated electromagnetic force attracts the valve core, so that the sealing surface between the valve core and the valve seat is separated, and the medium can be accessed; When the electromagnet is de-energized, the electromagnetic force disappears, and the pressure of the spring or the medium itself resets the valve core, so that the sealing surface between the valve core and the valve seat is closed, and the medium stops the passage. The control of the medium is achieved by controlling the on/off of the electromagnet.
3. Selection parameters of high-pressure solenoid valves.
1.Valve body material: The body material of high-pressure solenoid valve is usually made of corrosion-resistant materials such as stainless steel and copper alloy to adapt to the use environment under various harsh working conditions.
2.Valve port diameter: according to the medium flow and pressure to determine the valve port diameter, in general, the flow rate, high pressure occasions need to choose a large diameter of the high-pressure solenoid valve.
3.Working pressure: When selecting a high-pressure solenoid valve, it is necessary to consider the working pressure range of the medium to ensure that the selected products can meet the requirements of the actual working conditions.
4.Control mode: according to the actual control requirements, choose normally open or normally closed high-pressure solenoid valves, as well as different types of products such as one-way control or two-way control.
5.Temperature range: Considering the temperature range of the medium, select high-pressure solenoid valve products that can adapt to the temperature requirements under actual working conditions.
Fourth, the brand selection of high-pressure solenoid valves.
In the market, there are many high-pressure solenoid valve brands to choose from, such as Fuji Electric, SMC, Honeywell and other well-known brands. When choosing a brand, there are a few things to consider:
1.Brand awareness: Choose a well-known brand, which can usually guarantee product quality and after-sales service.
2.Technical support: Some well-known brands have strong technical support teams that are able to provide professional technical advice and solutions.
3.Products**: Products of different brands vary greatly and need to be selected according to the actual budget.
4.Product performance: Compare the product performance parameters of different brands and choose the products that meet your needs.
V. Conclusion. As an indispensable control component in the field of industrial automation, high-pressure solenoid valves need to consider many factors in the purchase process. By understanding its working principle, selection parameters and brand selection, I believe readers have a clearer understanding of how to choose a high-pressure solenoid valve that suits their needs. In the future engineering practice, it is hoped that readers can choose high-pressure solenoid valve products with superior performance and reliable quality according to the guide provided in this article, so as to provide strong support for the smooth progress of the project.
