The pipeline filter with an overflow valve is a specialized filtration equipment that integrates the functions of filtration and overflow control, primarily used in hydraulic systems to purify the medium and regulate system pressure. Below is a detailed introduction to this type of pipeline filter:
I. Working Principle
During operation, the pipeline filter with an overflow valve first filters the medium in the pipeline through its internal filter element, removing impurities, particles, suspended solids, and other contaminants to ensure the purity of the medium. Simultaneously, when the system pressure exceeds the preset safety limit, the overflow valve automatically opens, allowing excess medium (such as hydraulic oil) to flow back to the reservoir through the valve, thereby protecting the system from the adverse effects of excessive pressure.
II. Structural Characteristics
Filter Element: Typically made of corrosion-resistant materials like stainless steel, it boasts excellent filtration efficiency and high-temperature resistance. The filter element comes in various forms, such as pleated and cartridge types, to cater to diverse filtration requirements.
Overflow Valve: Integrated within the filter and connected to the piping system, the overflow valve promptly responds when the system pressure exceeds the set limit, opening a relief channel to discharge excess medium.
Housing: Constructed from sturdy and durable materials, the housing safeguards the internal components and withstands system pressure.
III. Application Areas
The pipeline filter with an overflow valve finds extensive application in hydraulic systems, lubrication systems, cooling systems, and other scenarios requiring precise pressure control and medium filtration. For instance, in industries like metallurgy, chemicals, power generation, and machinery, these filters are employed to safeguard equipment from contamination and excessive pressure, enhancing system stability and reliability.
