Water seal of high temperature resisting material isolates spring working parts from water during relief.

在泄压时,耐高温材料的水密封部件将水与其它活动部件隔离开来

属类：产品说明书-热水器说明-

An ASME Section IV certified pressure relief valve shall be installed on each boiler as noted. The valve shall have a BTU rating in excess of the BTU rating of the boilers heating output.

正如ASME(美国机械工程师协会)第四节所规定,每个锅炉都应该安装经过ASME认证的压力安全阀。这些安全阀额定的BTU必须超过锅炉加热过程所产生的BTU。

Each hot water space heating boiler shall be equipped with a pressure relief valve set to relieve below the maximum boiler working pressure.

每个热水供暖锅炉都必须配置压力安全阀,其设置的泄压压力必须小于锅炉的最大工作压力。

The safety valve shall feature a raised seat and non-mechanical disc alignment. Working parts and spring shall be isolated from any discharge by a high temperature resistant material.

安全阀必须配置凸出的阀座和非机械式阀瓣排列。活动部件和弹簧都应该耐采用高温材料密封件将其与排泄水隔离开来。

属类：产品说明书-热水器说明-

As thermal expansion conditions develop, pressure builds up to the setting of the relief valve. This will cause discharging of small quantity of water.

随着热量的增加,压力也随着增加,并达到安全阀的压力设置。此时将导致安全阀排泄出少量的水。

Should operating controls fail, permitting runaway firing, the boiler water may reach steam temperatures. The valve will then open to discharge steam at the rate or faster than the boiler can generate it, thus restoring system pressure to a safer level.

如果操作控制失效，火源又没有关闭，锅炉内水温将达到蒸汽高温。此时，安全阀将开启并以等于或大于锅炉所能产生蒸汽的能力排泄蒸汽，从而使得系统压力恢复到安全状态。

属类：产品说明书-热水器说明-

The discharge line must be the same size as the valve outlet, and must pitch downward from the valve to a safe place for disposal.

排泄管道必须与安全阀出口具有相同的口径,必须从安全阀的下方接到安全排放地点。

属类：产品说明书-热水器说明-

Valve lever must be tripped at least once a year to insure that waterways are clear. Safety valve is designed for emergency safety relief and shall not be used as an operating control.

阀门手柄每年至少要使用一次,以确保水路畅通。安全阀用于危机状态下的安全泄压,不应该作为操作控制的工具。
