Y-STRAINER VALVE FLANGE END

First, the filter design standards and use:<br /> Y-type filter in accordance with HG / T2163-1991 standard water supply and drainage design, manufacture, there are interfaces in the form of flange and groove connections, according to ``JB / T9092, the valve inspection and testing 'inspection and testing, with a medium temperature adaptation -20 ~ 300 ℃ of water or other fluids, products used in petroleum, chemical, water vapor, metallurgy, heating, fire fighting water supply and drainage, as the filter pipeline row impurity effect, and may be available for filter media according to user requirements different filter (20 mesh to 180 mesh). Eliminate impurities media to protect the normal use of equipment. To ensure that the device has a good sewage inlet end performance.

The main performance parameters

Second, the structural characteristics and working principle:
Simple structure, high reliability, long life;

Structure Introduction

Easy disassembly, easy to clean and maintain;
Filter area, flow coefficient small group, a lower end portion provided with free flushing device, the filter specifications, to meet the requirements of different occasions filter;
4. Y-type filter to remove a small amount of solid particles in a liquid device, it can protect the normal operation of the apparatus, when the fluid is set into a certain size filter cartridge, its impurities are blocked, and clean filtrate from the Y-type filter outlet. When you want to clean, just take out the filter removed, you can reload after treatment.
Y-type filter structure:

Main parts and materials:

No. Part Name Material
1 Virological QT500-7
2 Strainer 304
3 Screw nut Carbon steel
4 Screw Carbon steel
5 Foreign plugs Copper
6 Filter cover QT500-7
7 Gaskets EPDM

Structure Introduction

Third, the installation and maintenance of:
1. Y-type filters can be installed horizontally or vertically downward direction of the arrow on the import and export orientation and the body should be consistent.
2. the filter and water treatment equipment for use, water treatment equipment should be installed in the front-end intake.
3. there should be between the filter and the actuator or meter distance is generally more than the nominal diameter of 6 to 10 times.
4. the proposed bypass, in order to filter the normal operation of cleaning or failure does not affect the system.
5. the filter of the core parts of the filter core, a filter from the filter frame filter screen, filter easily damaged, in need of protection.
6. when the filter is working for some time, the filter core precipitate impurities open plug before discharge.
7. the filter components need regular cleaning, cleaning agents and cleaning cycle is determined by the user according to their own conditions of use.
8. each maintenance, before cleaning, and should filter system with pressure isolation. After cleaning, re-install the seal is damaged, use a new Gaskets.

Structure Introduction

Fourth, the use of note:
1. note that when Y filter loading not violent bump, or easily damaged.
2. Y-type filters can not be installed using the operating pressure exceeds its rated working pressure of the pipeline.
3. Y type filter is not available for less than the rated temperature piping systems installed in the device does not allow flow back end.
4. each maintenance, before cleaning, and should filter system with pressure isolation. After cleaning the filter back in after installing the filter, observe the filter gasket for leaks happen, if a leak is discovered, the timely replacement of gaskets.

Structure Introduction

Fifth, failure and troubleshooting:

Failure may occur, causes and troubleshooting

Symptom Causes may occur Elimination
Filter distortion Not properly installed Use the correct installation method
Severe bump Handle with care
Virological filter cover leaks Gaskets Replace the seals, fastening
The outer tube stop leaks Seal damage Replace the seals, fastening
