The one-way solenoid valve is a commonly used fluid control component, mainly used to achieve the on-off control, regulation and distribution of fluids. Its realization principle is to control the movement of the valve core through electromagnetic force, thereby changing the open and closed state of the fluid channel to achieve the control and regulation of fluids.
Firstly, the structure of the one-way solenoid valve consists of two parts: the electromagnetic part and the valve body part. Among them, the electromagnetic part includes the electromagnetic coil, iron core, spring, etc., which is mainly responsible for generating electromagnetic force; the valve body part includes the valve seat, valve core, sealing ring, etc., which is mainly responsible for controlling the on-off of the fluid. When the electromagnetic coil is energized, the generated electromagnetic force attracts the iron core, which in turn drives the valve core to move upward, opening the valve port and allowing the fluid to pass; conversely, when the electromagnetic coil is de-energized, the iron core loses its attraction, the valve core moves downward under the action of the spring, the valve port closes and the fluid flow is cut off. By controlling the on-off of the electromagnetic coil with different electromagnetic signals, the control and regulation of the fluid can be achieved.
Secondly, the working principle of the one-way solenoid valve has two ways: direct type and guided type. The inside of the valve body of the ultra-high pressure one-way solenoid valve is a direct channel, and the fluid passes directly along the channel when the valve core is open; when the valve core is closed, the fluid is cut off. The inside of the valve body of the guided one-way solenoid valve contains multiple guide holes or guide grooves. Different positions of the valve core can change the direction and position of the fluid inlet and outlet channels to achieve multi-directional control and regulation of the fluid.
In addition, the application range of one-way solenoid valves is very wide, mainly involving industrial automation, machinery manufacturing, petrochemical industry, pharmaceutical production, water treatment, environmental protection and other fields. For example, in industrial automation, one-way solenoid valves can be used in conjunction with control systems such as PLC to complete the fluid control and regulation in the automated production process; in the petrochemical industry, one-way solenoid valves can be used for the control and regulation of oil and gas pipelines to ensure the normal transportation and processing of oil and gas; in the water treatment industry, one-way solenoid valves can be used for the control and regulation of sewage treatment and water purification systems to improve the efficiency of water resource utilization, etc.
In conclusion, the one-way solenoid valve is a very important fluid control component that realizes the control and regulation of fluid on-off through electromagnetic force. Its application scenarios are very wide, which can not only improve production efficiency and product quality, but also contribute to people’s life and health protection.
Holian has been engaged in the manufacturing of spare parts for oxygen concentrator, such as solenoid valves, pressure regulating valves and check valves, for more than ten years. During the process of cooperating with numerous oxygen generator manufacturing enterprises and maintenance enterprises, it has accumulated rich technical experience and exquisite manufacturing techniques.
Meanwhile, considering the complex and changeable situations that oxygen generator maintenance enterprises face in various markets, Holian has demonstrated remarkable market adaptability. It has specifically selected elite personnel to form a special technical team, which has conducted in-depth investigations into the popular oxygen generator product models, common failure modes and maintenance pain points in different markets, and then developed accessories with extremely high universality accordingly. These universal accessories are just like master keys that can be adapted to a variety of oxygen concentrator of different brands and models but are widely popular in the local areas, which has greatly reduced the inventory pressure and procurement costs of spare parts for maintenance enterprises, brought unprecedented convenience to maintenance work, and thus won wide acclaim and deep trust from maintenance enterprises and end customers. The brand reputation has spread rapidly in the industry like a snowball.
The key secret that supports Holian’s technical team to make great progress and continue to improve all the way lies in its high attention to customer feedback. Whether it is the optimization suggestions put forward by manufacturing enterprises or the actual usage problems fed back by maintenance enterprises, Holian regards them all as extremely precious sources of inspiration for research and development. It organizes teams to conduct repeated discussions and simulation experiments, so that each product iteration and upgrade closely meets the market demands and truly realizes a customer-centered approach.
In the chain of ensuring product supply, Holian’s logistics department also plays an indispensable and crucial role, providing a strong backup support for the smooth operation of the entire business. For small-batch orders from small maintenance shops, start-up oxygen generator enterprises or temporary replenishment needs, Holian’s logistics team has shown extremely high flexibility and accurately matched global well-known courier companies such as Fedex and UPS. These courier companies, relying on their dense network layouts, efficient sorting processes and rapid transportation timeliness, ensure that each small package can start from Holian’s factory at the fastest speed, travel across thousands of mountains and rivers, and be accurately delivered to customers’ hands to meet their urgent needs.
When facing the batch orders of large oxygen generator manufacturing enterprises or the massive shipment tasks during the peak sales season, Holian skillfully relies on powerful Chinese international logistics enterprises that are deeply involved in the international logistics field, such as COSCO Air Freight and Sinotrans Air Freight. By virtue of these giants’ large-scale air transportation resources, professional logistics planning capabilities and mature customs declaration and clearance experience, Holian, on the premise of ensuring the on-time delivery of goods, reasonably reduces the high logistics costs through a series of refined operations such as optimizing transportation routes and integrating container space, so that each batch of goods carrying Holian’s quality and customers’ expectations can be steadily delivered to customers all over the world on time, further strengthening Holian’s competitiveness in the international market.
