- Падрыхтуйце трубаправоды: Ensure piping is clean, free of debris, and properly aligned. Cut pipe ends squarely.
- Нанесці герметык для разьбы: Apply an appropriate thread sealant (e.g., PTFE tape or pipe dope) to the male pipe threads. Do not apply sealant to the valve's internal threads.
- Рэзьбовы клапан: Hand-tighten the valve onto the pipe. Use a pipe wrench on the hex flats of the valve body to tighten, ensuring not to overtighten or apply torque to the handwheel or bonnet.
- падтрымка: Provide adequate support for the piping system to prevent strain on the valve.
- тэст: Пасля ўстаноўкі павольна стварайце ціск у сістэме і праверце на наяўнасць уцечак ва ўсіх злучэннях.
5. Інструкцыя па эксплуатацыі
The NIBCO T133 gate valve is designed for on/off service. It is not intended for throttling or flow regulation.
- Каб адкрыць: Turn the blue handwheel counter-clockwise until it stops. The non-rising stem will remain in place while the internal wedge lifts to allow full flow.
- Каб закрыць: Turn the blue handwheel clockwise until it stops. The internal wedge will lower to completely block flow. Do not overtighten.
6. Тэхнічнае абслугоўванне
The NIBCO T133 gate valve with its screw-in bonnet is designed for infrequent maintenance. Regular inspection is recommended to ensure optimal performance.
- Звычайная праверка: Periodically check for any signs of external leakage around the bonnet or threaded connections.
- Праверка працы: Cycle the valve (open and close) occasionally to ensure smooth operation and prevent internal components from seizing.
- Уборка: Keep the exterior of the valve clean to prevent corrosion and allow for easy inspection.

7. Выпраўленне непаладак
| праблема | Магчымая прычына | Рашэнне |
|---|---|---|
| Leakage at threaded connections | Improper thread sealant application or insufficient tightening. | Depressurize system, reapply thread sealant, and retighten connections. |
| Leakage around stem | Loose packing gland or worn packing. | Gently tighten packing gland nut. If leakage persists, packing may need replacement by a qualified technician. |
| Valve difficult to operate (turn handwheel) | Lack of lubrication, internal debris, or overtightened packing gland. | Loosen packing gland slightly (if overtightened). If problem persists, internal inspection by a professional may be necessary. |
| Valve not fully closing/opening | Internal debris obstructing wedge travel or damaged wedge/seat. | Flush system if possible. If mechanical damage is suspected, valve replacement may be required. |
