| 5. | A . s . m . e rated * , csa listed . self - closing t & p relief valves for water heaters up to 100 , 000 btu / hr 2合1温度压力安全阀,对于温度过高,压力过大的紧急状态提供成本最低,最有效的保护方案。 |
| 6. | By doing so , the det keeps the system pressure below the relief setting of the temperature and pressure relief valve 通过这种功能, det系列将系统压力保持在温度压力安全阀的排放设置下。 |
| 7. | The combined 2 in 1 t & p relief valve provides the least expensive and proven means for protection against both excessive temperature and pressure emergency conditions 2合1温度压力安全阀,对于温度过高,压力过大的紧急状态提供成本最低,最有效的保护方案。 |
| 8. | Pressure relief valves should be tested periodically to ensure that the product has not been affected by corrosive water conditions and to ensure that the valve and discharge piping have not been altered or tampered with 压力安全阀应该定期进行测试,以确保安全阀不会受到腐蚀性水环境的影响,确保安全阀和排泄管道不被篡改或损坏。 |
| 9. | When a reducing valve is used , it makes a closed system ; therefore , a pressure relief valve must be installed in the downstream side of the regulator to protect equipment against excess pressure which is built up by the expansion of water from the domestic hot water supply tank or heater 如果采用减压阀,将形成一个封闭系统;因此必须在调节阀的下游位置安装一个压力安全阀,以保护设备不会由于室内热水供应容器或热水器造成的水膨胀而变得压力过大。 |
| 10. | Warning : reinspection of t & p relief valve : temperature and pressure relief valves should be inspected at least once every three years by a licensed plumbing contractor or authorized inspection agency , , to ensure that the product has not been affected by corrosive water conditions and to ensure that the valve and discharge line have not been altered or tampered with illegally 警告:重新检查温度压力安全阀:温度压力安全阀每年应该由有资格证书的管道承包商或经过批准的检查机构来至少检查一次,以确保这种产品不会受到腐蚀性水的影响,确保阀门和排泄管道不会被不合理的更换或损坏。 |
