설정 및 설치
올바른 설치를 위해 다음 단계를 따르세요.
- 시스템 준비: Ensure the system is depressurized and drained before installation. Clean all piping and fittings to prevent debris from entering the valve.
- 설치: Mount the valve in a location that allows for easy access for maintenance and inspection. The valve can be mounted in any position without affecting operation, but mounting with the solenoid upright is generally preferred to extend life.
- 파이프 연결: Connect the piping to the valve's NPT ports. Use a suitable thread sealant (e.g., PTFE tape or pipe dope) on the male threads. Do not overtighten connections, as this can damage the valve body. Ensure the flow direction matches the valve's design (if applicable, though for 3-way, ports are typically marked).
- 전기 배선: Connect the 125VDC power supply to the solenoid coil terminals. Ensure wiring conforms to all local electrical codes. Verify the voltage matches the coil's rating (125VDC).
- 누출 확인: After installation, slowly pressurize the system and check all connections for leaks using an appropriate leak detection method.
작동 지침
The Red Hat 3-Way Solenoid Valve is a normally closed (NC) valve. This means:
- 비활성화 상태: When no power is applied to the solenoid coil, the valve is in its normal (closed) state. In a 3-way normally closed configuration, this typically means one port is connected to a common port, and the third port is blocked or vented. For this specific valve, it means the inlet port is closed, and the exhaust port is open to the common port.
- 활성화 상태: When 125VDC power is applied to the solenoid coil, the valve shifts to its open state. The inlet port opens to the common port, and the exhaust port is closed.
To operate, simply apply or remove the specified DC voltage to the solenoid coil as required by your control system.
유지
Regular maintenance ensures optimal performance and extends the life of your solenoid valve. Always depressurize and disconnect power before performing any maintenance.
- 정기 검사: Regularly inspect the valve for signs of leaks, corrosion, or damage to the coil.
- 청소: If the valve is exposed to dirty media, periodic cleaning of internal components may be necessary. Consult a qualified technician for disassembly and cleaning procedures.
- 씰 교체: Over time, seals may wear out. Replacement kits are typically available from the manufacturer.
- 코일 확인: Ensure the coil is free from excessive heat buildup or physical damage.
문제 해결
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| 밸브가 열리거나 닫히지 않습니다. | 코일에 전원이 공급되지 않음; 볼륨이 잘못되었습니다tage; Damaged coil; Obstruction in valve; Low pressure differential | Check power supply and wiring; Verify voltage matches coil rating; Replace coil; Clean valve internals; Ensure minimum pressure differential is met |
| 밸브 외부 누출 | Loose connections; Damaged body or seals | Tighten connections (do not overtighten); Inspect and replace damaged seals or valve body |
| Valve leaks internally (passing fluid) | Worn seals; Debris lodged in valve seat | Replace internal seals; Disassemble and clean valve internals |
| Excessive coil heat | 잘못된 볼륨tage; Continuous duty cycle not intended for coil; High ambient temperature | 올바른 볼륨 확인tage. 필요한 경우 코일이 연속 작동에 적합한지 확인하십시오. 밸브 주변의 환기를 개선하십시오. |
