1. مقدمه
This manual provides essential information for the safe and effective installation, operation, and maintenance of your dot 1/2" Stainless Steel 316 WYE Strainer Mesh Filter Valve. Please read this manual thoroughly before installation and retain it for future reference.
The WYE strainer is designed to remove unwanted particles from liquid or gas pipelines, protecting downstream equipment from potential damage and ensuring system efficiency. Constructed from Stainless Steel 316, it offers excellent corrosion resistance and durability across a wide range of temperatures and media.
2. اطلاعات ایمنی
Observe the following safety precautions to prevent injury and damage to the product or system:
- Ensure the system is depressurized and drained before installation or maintenance.
- از تجهیزات حفاظت فردی (PPE) مناسب، از جمله دستکش و محافظ چشم استفاده کنید.
- Verify that the strainer's material and pressure rating are suitable for the application.
- Do not exceed the maximum operating pressure or temperature.
- نصب و نگهداری فقط باید توسط پرسنل واجد شرایط انجام شود.
3. محصول تمام شدview
The dot 1/2" Stainless Steel 316 WYE Strainer is a Y-shaped device used to mechanically remove solids from flowing liquids or gases by means of a perforated or wire mesh straining element. It is typically installed in a pipeline to protect pumps, meters, control valves, steam traps, regulators, and other process equipment.

5. راه اندازی و نصب
- آماده سازی: Ensure the pipeline is clean and free of debris. Verify that the strainer's flow direction arrow (if present) aligns with the system's flow.
- موقعیت یابی: Install the WYE strainer in a horizontal or downward-sloping position to allow for proper collection of debris in the screen and easy access for cleaning.
- اتصال: Apply appropriate thread sealant (e.g., PTFE tape or pipe dope suitable for stainless steel and the media) to the male pipe threads. Carefully thread the strainer into the pipeline connections, ensuring a tight, leak-free seal. Do not overtighten.
- پشتیبانی: Provide adequate support for the strainer and associated piping to prevent stress on the connections.
- تست کردن: After installation, slowly pressurize the system and check for leaks. Rectify any leaks immediately.
6. دستورالعمل های عملیاتی
Once installed and the system is operational, the WYE strainer functions passively by filtering particles from the flowing media. No active operation is required beyond initial installation.
- جهت جریان: Ensure the media flows in the direction indicated by the arrow on the strainer body.
- Pressure Drop Monitoring: Monitor the pressure differential across the strainer. An increase in pressure drop indicates that the screen is accumulating debris and requires cleaning.
7. تعمیر و نگهداری
Regular maintenance is crucial for the optimal performance and longevity of the WYE strainer.
- Screen Cleaning Frequency: The frequency of cleaning depends on the amount of debris in the system. Initially, check the screen frequently (e.g., weekly) and adjust the schedule as needed.
- روش تمیز کردن:
- Isolate the strainer by closing upstream and downstream valves.
- Depressurize and drain the section of the pipeline containing the strainer.
- Carefully unscrew the hexagonal cap at the bottom of the "Y" branch.
- Remove the mesh screen.
- Clean the screen using a brush and appropriate cleaning solution (e.g., water, mild detergent). Ensure all debris is removed. Inspect the screen for damage or tears. Replace if damaged.
- Reinsert the clean screen into the strainer body.
- Replace the cap, ensuring the gasket (if present) is properly seated. Tighten securely but do not overtighten.
- Slowly return the system to pressure and check for leaks.

8 عیب یابی
| مشکل | علت احتمالی | راه حل |
|---|---|---|
| Reduced flow/Increased pressure drop | Clogged mesh screen | Clean the mesh screen (refer to Section 7). |
| Leakage at cap | Improperly seated cap or damaged gasket | Depressurize, remove cap, inspect/replace gasket, re-tighten cap. |
| Leakage at pipe connections | Insufficient thread sealant or improper tightening | Depressurize, disassemble, reapply thread sealant, re-tighten connections. |
