3. 제품 오버view
The Febco Series 860 Reduced Pressure Zone (RPZ) Assembly is a backflow prevention device designed to prevent the backflow of contaminated water into the potable water supply. It features a bronze body construction with quarter-turn shutoff valves for isolation and test cocks for field testing.

그림 1: Febco 1313 860 Reduced Pressure Zone Assembly. This image displays the complete bronze assembly with two blue quarter-turn shutoff handles on either side, and multiple test cocks on the top and bottom sections. An arrow indicates the direction of water flow.
주요 구성 요소:
- Inlet Shutoff Valve: Controls water flow into the assembly.
- Outlet Shutoff Valve: Controls water flow out of the assembly.
- Reduced Pressure Zone: The central section containing two independently operating check valves and an automatically operating differential pressure relief valve.
- 테스트용 수탉: Ports for connecting test equipment to verify proper operation.

5. 설정 및 설치
Installation of the Febco Series 860 RPZ Assembly requires adherence to local plumbing codes and should be performed by a licensed plumber or certified backflow prevention specialist.
- 사이트 선택: Choose a location that is easily accessible for testing and maintenance, protected from freezing, and allows for proper drainage of the relief valve discharge.
- Piping Preparation: Ensure the piping system is clean and free of debris. Flush the upstream piping thoroughly before connecting the assembly.
- 정위: Install the assembly in the correct orientation as indicated by the flow arrow on the body (refer to Figure 1). The assembly must be installed horizontally.
- 사이: Use appropriate female threaded connections. Apply pipe sealant or Teflon tape to male threads only. Do not overtighten connections.
- 지원하다: Provide adequate support for the assembly to prevent stress on the piping.
- Initial Pressurization: Slowly open the upstream shutoff valve to gradually fill the assembly and piping. Allow air to escape through the test cocks or by slightly opening the downstream shutoff valve.
- Relief Valve Screws: During initial pressurization or after maintenance, ensure the four screws near the relief valve discharge are positioned correctly. These screws should be turned horizontally (parallel to the ground) to prevent water from shooting out. Their purpose is typically for air release or specific testing procedures.
6. 사용 설명서
The Febco Series 860 RPZ Assembly operates automatically to prevent backflow. User interaction is primarily for isolation during maintenance or testing.
- 정상 작동: Both inlet and outlet quarter-turn shutoff valves should be fully open. The device will automatically maintain a reduced pressure zone to prevent backflow.
- 물 차단하기: To isolate the assembly, first close the downstream quarter-turn shutoff valve, then close the upstream quarter-turn shutoff valve. This prevents water hammer.
- Restoring Water: To restore water flow, slowly open the upstream quarter-turn shutoff valve, then slowly open the downstream quarter-turn shutoff valve.
7. 유지관리
Regular maintenance is crucial for the continued proper function and compliance of your backflow prevention assembly.
- 연간 테스트: This assembly must be tested annually by a certified backflow prevention device tester to ensure it is operating correctly and in compliance with local regulations.
- 시각적 검사: Periodically inspect the assembly for any signs of leaks, corrosion, or damage. Ensure the area around the relief valve discharge is clear and allows for proper drainage.
- 겨울철 : In climates where freezing temperatures occur, the assembly must be properly winterized to prevent damage. This typically involves shutting off the water supply, draining the assembly, and insulating it. Consult local guidelines for specific winterization procedures.
