安全阀

If refinery staff detects a higher-than-intended pressure in the space between the rupture disk and the relief valve, then the situation can be investigated, evaluated, and remedied.

如果炼厂职员发现爆破片和安全阀之间的压力超过正常的压力，这情况就能被检查、评估和纠正。

On the other hand, if the rupture disk experiences a pinhole leak, the pressure in the space between the rupture disk and the relief valve can equalize with the system pressure.

另一方面，如果爆破片出现泄露，爆破片和安全阀之间的压力就等于系统压力。

In such cases, provision should be made to always vent above flood level or for a pit drain to ensure an adequate air gap below the relief port.

如果要在坑内更换，则应该采取措施保证排放总是在地面上。或者，对于坑内排放，确保在安全阀下方配置适当的气隙。

The petrochemical industry mainly uses API standard gate valve, globe valve and check valves; electricity sector, mainly in power stations using high-temperature pressure valve, globe valve, check valve and safety valve, and part Reducing Valves of the low-pressure water supply and drainage valve butterfly valve, gate valve; the chemical industry mainly uses stainless steel valve, globe valve, check valve; metallurgical industry mainly uses low-voltage large-diameter butterfly valve, oxygen valve and oxygen valves; urban construction department used mainly low-pressure valve, such as urban water mainly in the large-diameter pipeline valve, the main floor, blending the building used by the center line butterfly valve, urban heating mainly in the metal sealing butterfly valve and so on; oil pipeline used mainly flat gate valve and ball valve; the pharmaceutical industry mainly uses stainless steel ball valve; the food industry mainly uses stainless steel ball valve and so on.

石化行业主要采用API标准的闸阀、截止阀和止回阀；电力部门主要采用电站用高温压闸阀、截止阀、止回阀和安全阀及一部分给排水阀的低压蝶阀、闸阀；化工行业主要采用不锈钢闸阀、截止阀、止回阀；冶金行业主要采用低压大口径蝶阀、氧气截止阀和氧气球阀；城市建设部门主要采用低压阀，如城市自来水管道主要采用的大口径闸阀，楼寓建设主要采用的中线蝶阀，城市供热主要采用的金属密封蝶阀等；输油管线主要采用平板闸阀和球阀；制药行业主要采用不锈钢球阀；食品行业主要采用不锈钢球阀等。
