Y-type filter capable of discharging sewage on line

Abstract

The invention belongs to the technical field of filtration of pipeline systems, and particularly relates to a Y-type filter capable of discharging sewage on line. The invention aims at developing theY-type filter capable of discharging the sewage on line. The Y-type filter is convenient to install, operate and maintain, capable of achieving the function of discharging the sewage on line after installation and good in sewage discharge effect, and the running demands of a system are not affected during sewage discharge. The filter is characterized by comprising a filter cylinder, a locating support ring, a cleaning brush assembly, a first O-type sealing ring, an end cover, a handle, a second O-type sealing ring, a shaft sleeve, a sewage discharge valve, a sealing ring gland and a filteringbarrel. The filter has the advantages that the structural strength is high, the pressure resistance effect is good, the corrosion resistance is excellent, the internal and external structures are attractive, the smooth finish of the internal and external surfaces is high, the transition of the internal circulation area is smooth, the operation and maintenance are convenient, and the online sewagedischarge effect is good. The sewage is effectively discharged on line, various risks caused by isolating overhaul are greatly reduced at the same time, and the running reliability of equipment and the running efficiency of a system are improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline system filtration, and in particular relates to a Y-shaped filter capable of on-line sewage discharge. Background technique [0002] Y-type filter is an indispensable filter device for the pipeline system of conveying medium. Y-type filter is usually installed at the inlet of pressure reducing valve, pressure relief valve, fixed water level valve or other equipment to remove a small amount of solid in the medium. The small equipment with particles can protect the normal operation of the equipment. When the fluid enters the filter cartridge with a certain size filter, the impurities are blocked, and the clean filtrate is discharged from the filter outlet. When it needs to be cleaned, just put it The disassembled filter cartridge is taken out and reinstalled after processing. None of the Y-type filters stipulated in the current national standards can conveniently realize online sewage discharge. A...

Problems solved by technology

None of the Y-type filters stipulated in the current national standards can conveniently realize online sewage discharge. After checking the national patent network, there is no corresponding online sewage discharge Y-type filter. During the operation of nuclear power plants, the important pumps involved in some systems Shaft seal water isolation is more complicated and difficult, and it takes time and effort to isolate the sewage, and there are certain industrial safety risks. Therefore, a filter that can discharge sewage online is needed, and it can meet the needs of system operation when the filter is discharged online.
