Basic Introduction to Y-Type Filters

     The Y-type filter is an indispensable filtering device in pipeline systems for conveying media. It is typically installed at the inlet end of减压阀 (reducing valve),泄压阀 (relief valve),定水位阀 (level control valve), or other equipment, primarily functioning to remove

Impurities in the medium are removed to ensure the normal operation of valves and equipment. The Y-type filter boasts advanced structure, low resistance, and easy draining, making it suitable for various mediums, including water, oil, and gas.

Its application scope is extensive.Applicable to a wide range of industries, including metallurgy, chemical, petrochemical, papermaking, food, mining, and electricity.

The working principle of the Y-type filter:

The working principle of the Y-type filter is to filter impurities in the medium through its internal mesh structure. When the liquid passes through the filter, solid impurities are blocked by the mesh, while the clean fluid is discharged through the mesh.

When cleaning is needed, simply remove the detachable filter cylinder, clean out the impurities, and reinsert it for easy maintenance.

Application Range of Y-Type Filters:

Y-type filters are suitable for a variety of media, including water, oil, and gas. The mesh size for water flow is typically 18-30, for air flow 10-100, and for oil flow 100-480. The Y-type filter is applicable in the chemical and petrochemical industries.

Our company's refrigeration, food, and various other industries can handle materials with low corrosiveness, corrosive materials, and those with hygiene requirements.

Structural Features of the Y-Type Filter:

The Y-type filter boasts advanced structure, low resistance, and easy draining features. Its typical structure includes a cylinder, stainless steel filter mesh, drainage section, transmission device, and electrical control components. The filter is manufactured from stainless steel.

The inner tube is a perforated filter sleeve made of stainless steel thin plate, tightly fitted with a wire mesh structure, featuring a quick-release joint for easy disassembly and cleaning.

‌Please note the following points when using the Y-type filter:‌

Installation Direction:During installation, the Y-type filter must have the water flow direction aligned with the arrow on the valve, which can be mounted horizontally or vertically.

2. Sealability InspectionAfter installation, check if the filter is leaking. If a leak is detected, it may be due to a damaged sealing washer, which requires replacement.

3. Pressure Gauge InstallationPressure gauges should be installed at the inlet and outlet of the Y-type filter to monitor the pressure on both sides of the pipeline filter for normalcy.

 ‌4. Effluent and Backflush OperationsTo facilitate effluent discharge and cleaning of debris from the filter screen, Y-type filters should be designed with bypass piping. During normal operation, the bypass valve must be closed. When effluent discharge or backwashing of the filter screen is required, the inlet and outlet valves should be closed, and the bypass valve opened for pressure-free discharge. To thoroughly rinse away debris at the bottom of the cylinder and any dirt adhered to the filter screen, the outlet valve of the pipeline filter, which has been closed, can be slightly opened.

Flow rates are appropriately controlled, allowing the majority of water to continue recirculating, while a small portion returns to the filter for backflushing.

Regular CleaningThe Y-type filter requires regular cleaning after a period of use to maintain its filtration efficiency. The frequency of cleaning depends on operating conditions, typically not more than once a week.

6. Maintenance and ReplacementFor Y-type filters required in high humidity and high-temperature environments, filters with high-temperature resistance must be selected. For biological cleanrooms, filters with metal frames should be used, and their surfaces should be resistant to rust.

 7. Environmental AdaptabilityThe Y-type filter should be installed on a stable foundation and avoid placement in an unstable environment. Before maintenance, remove the filter screen after confirming there is no gas inside the filter.

Wash with soap and water, then air dry naturally, and reassemble.
