泄壓閥的檢查與維護（中英文）
Pressure Relief Valve Inspection and Maintenance
每次容器裝滿時都應檢查泄壓閥，而且每年至少檢查一次。一旦泄壓閥有任何異狀，就必須更換它。
Relief valves should be inspected each time the container is filled but no less than once a year. If there is any doubt about the condition of the relief valve, it must be replaced.
決定泄壓閥“壽命”的主要因素
Major Factors to determine “Life” of Relief Valves
? 積水/積冰
Water/Ice Accumulation
? 腐蝕
Corrosion
? 污垢——碎屑
Dirt – Debris
? 損害
Damage
? 正常老化
Normal Aging
在壓力下檢查泄壓閥時必須戴護目鏡。 切勿在壓力下直視泄壓閥，或將身體的任何部位放在泄壓閥排放可能影響的位置。 在某些情況下，建議在進行目視檢查時使用手電筒和小鏡子來提供幫助。
Eye protection must be worn when performing inspection on relief valves under pressure. Never look directly into a relief valve under pressure or place any part of your body where the relief vale discharge could impact it. In some cases, a flashlight and a small mirror are suggested to assist when making visual inspections.
1 防雨帽 / Rain cap
檢查位于閥門中或管道末端的保護帽是否安裝牢固。保護帽有助于保護泄壓閥免受雨、雨夾雪、雪、冰、沙、污垢、鵝卵石、昆蟲、其他碎屑和污染物可能引起的故障。 立即更換損壞或丟失的蓋子，并始終保持蓋子在原位。
Check protective cap located in valve or at end of pipe away for a secure fit. Protective caps help protect the pressure relief valve against possible malfunction caused by rain, sleet, snow, ice, sand, dirt, pebbles, insects, other debris and contamination. REPLACE DAMAGED OR MISSING CAPS AT ONCE AND KEEP A CAP IN PLACE AT ALL TIMES.
2 打開排水孔 / Open weep holes
污垢、冰、油漆和其他異物會妨礙閥體正常排水。 如果無法清除滲漏孔，請更換泄壓閥。
Dirt, ice, paint and other foreign particles can prevent proper drainage from the valve body. IF THE WEEP HOLES CANNOT BE CLEARED, REPLACE THE PRESSURE RELIEF VALVE.
3 泄壓閥彈簧老化腐蝕 / Deterioration and corrosion on pressure relief valve spring
暴露于高濃度的水、鹽、工業(yè)污染物、化學品和道路污染物中可能會導致金屬部件失效。 如果彈簧上的涂層破裂或碎裂，請更換泄壓閥。
Exposure to high concentrations of water, salt, industrial pollutants, chemicals and roadway contaminates could cause metal parts to fail. IF THE COATING ON THE SPRING IS CRACKED OR CHIPPED, REPLACE THE PRESSURE RELIEF VALVE.
4 物理損壞 / Physical damage
積冰和不正確的安裝可能會導致機械損壞。 如果有任何損壞跡象，請更換泄壓閥。
Ice accumulations and improper installation could cause mechanical damage. IF THERE ARE ANY INDICATIONS OF DAMAGE, REPLACE THE PRESSURE RELIEF VALVE.
5 篡改或重新調整 / Tampering or readjustment
泄壓閥在出廠時設置為在指定壓力下排放。如果有任何篡改或重新調整的跡象，請更換泄壓閥。
Pressure relief valves are factory set to discharge at specified pressure. IF THERE ARE ANY INDICATIONS OT TAMPERING OR READJUSTMENT, RELPACE THE PRESSURE RELIEF VALVE.
6 閥座泄漏 / Seat leakage
使用非腐蝕性泄漏檢測溶液檢查閥座區(qū)域是否有泄漏。如果有任何泄漏跡象，請更換泄壓閥。 切勿強行關閉泄壓閥并繼續(xù)使用。這可能會導致閥門損壞，并可能導致安裝減壓閥的容器或管道破裂。
Check for leaks in the seating area using a non-corrosive leak detection solution. REPLACE THE PRESSURE RELIEF VALVE IF THERE ARE ANY INDICATION OF LEAKAGE. Never force a pressure relief valve closed and continue to leave it in service. This could result in damage to the valve and possible rupture of the container or piping on which the pressure relief valve is installed.
7 腐蝕和污染 / Corrosion and contamination
如果有任何腐蝕或污染的跡象，請更換泄壓閥。
REPLACE THE PRESSURE RELIEF VALVE IF THERE ARE ANY SIGNS OF CORROSION OR CONTAMINATION.
8 泄壓閥中有水分、異物或污染物 / Moisture, foreign particles or contaminates in the pressure relief valve
泄壓閥部件中的油漆、焦油或冰等異物會影響閥門的正常工作。 放置在閥體中的潤滑脂可能會隨著時間的推移變硬或聚集污染物，從而影響減壓閥的正常運行。 請勿在閥體中加入潤滑脂。 如果有任何跡象表明有水分或異物，請更換泄壓閥。
Foreign material such as paint, tar or ice in pressure relief valve parts can impair the proper functioning on the valves. Grease placed in the valve body may harden over time or collect contaminates, thereby impairing the proper operation of the pressure relief valve. DO NOT PLACE GREASE IN THE VALVE BODY. REPLACE THE PRESSURE RELIEF VALVE IF THERE ARE ANY INDICATIONS OF MOISTURE OR FOREIGH MATTER.
9 容器連接處腐蝕或泄漏 / Corrosion or leakage at the container connection.
使用非腐蝕性泄漏檢測溶液檢查容器與泄壓閥的連接。 如果連接處和容器有任何腐蝕或泄漏跡象，請更換泄壓閥。
Check container to pressure relief valve connection with a non-corrosive leak detection solution. REPLACE THE PRESSURE RELIEF VALVE IF THERE IS ANY INDICATION OF CORROSION OR LEAKAGE AT THE CONNECTION AND CONTAINER.
注意 / Caution：
切勿堵塞減壓閥的出口。 任何用于停止正常運行的泄壓閥的流動的裝置都會引起嚴重的安全問題。
Never plug the outlet of a pressure relief valve. Any device used to stop the flow of a properly operating pressure relief valve that is venting an overfilled or over pressurized container – raises serious safety concerns.
