瓣阀

Should re-adjust the amount of compression spring or a heavy hammer position; valve flap and valve seat stick.

应重新调整弹簧的压缩量或重锤的位置；阀瓣与阀座粘住。

To examine the seat, continue spring compression until the clapper has moved approximately 1 from the seat.

检查阀座，继续压缩弹簧直到阀瓣丛阀座上移动大约1英寸。

The following procedures provide information for replacing the diaphragm, the relief valve disc, and the relief valve seat.

下列提供的资料是更换隔膜、安全法阀瓣和安全法阀座的程序。

Following testing and soon after commissioning of a system, if either the Model-B or Model-C valve develops a leak at the top bearing, the flange face-seal, and/or across the valve disk, the most likely suspicion would be inappropriate selection of the elastomeric seat and seals.

在系统测试和试运转后不久，如果型号B或型号C阀门的任何一种在阀门的顶部轴承、法兰面密封，以及阀门阀瓣等部分出现了泄漏，则很有可能是由于选择了错误的弹性材料阀座和密封。

After extended operation, if leakage should occur at the top bearing or across the valve disk of either the Model-B or Model-C valve, this is an indication of wear to the elastomeric seat and/or O-ring seals, requiring their replacement. In most cases, valve replacement will be found less expensive than parts replacement.

在进行操作后，如果泄露出现在型号B或型号C阀门的顶部轴承或阀门阀瓣上，则表明弹性材料阀座和/或O形环密封出现磨损，这时就需要进行更换。

Thus, the combination of a sensitive, powerful thermostatic force combined with a free-moving, high-temperature-resisting rubber disc assures longer valve life and more satisfactory system performance.

因此，这种灵敏有力的温度调节装置组合体，结合自由移动、耐高温橡胶阀瓣确保了更长的阀门使用寿命和更令人满意的工作性能。

The level of valve lift check valve should be installed in horizontal pipelines.

升降式水平瓣止回阀应安装在水平管道上。

Vertical valve lift check valve should be installed in the vertical pipe.

升降式垂直瓣止回阀应安装在垂直管道上。

The seat, disc and pivot pins are combined into one subassembly secured to the inlet side of the body with a locking ring in sizes 3 and smaller.

阀座，阀瓣和枢轴销构成一个分总成，采用尺寸3英寸或更小的锁环固定在阀体进口一侧。

Flap valve pin and WA44C Type Pound-Grade Balance Bellows Spring-Loaded Safety Valvevalve shaft axial clearance between the bearing face not less than 0.25mm.

阀瓣轴销与阀体支承端面之间的轴向间隙不应小于0.25mm。
