 使用指导：

 向球阀加注VAL-TEX阀门清洗液的步骤

1.    如有可能，操作阀门以确定他的状况。球体的动作将有助于移出阀门内部的碎屑和堆积物。

2.     将阀门置于全开或全关位置。

3.     确定阀座密封脂注嘴的数量。一般有2个或4个注嘴。

4.    从用量卡上找到你阀门的类型、尺寸和用量。你阀门的总用量是清洗液加注的最小量。

5.    将总用量除以两个阀座密封脂注嘴的总数量。你应该将阀门清洗液通过密封脂注嘴注入一个阀座。然后采用同样的步骤清洗另一个阀座。记住在液压注枪上作记号以纪录你注入的量。从注枪的螺纹炳上计量，每11/8英寸=1盎司。

   如果阀门是埋地的，注嘴延长管的容积必须增加到注入量的计算

Inside Diameter内径        OuncesPer Foot 盎司/英尺

1/4                      0.5

3/8                      1.3

1/2                      2.0

3/4                      4.0

6.    采用缓慢和均匀的压力来注入清洗液。这样可以有助于持续的流速和均匀的分配。快速的加注能引起清洗液从边缘或防垃圾密封或O型环变形处溢出。许多球阀的防垃圾密封设计无法保持压力。当操作时，可以使用带15,000psi压力表的液压手动枪。使用这种注枪能让操作者比使用机械式或气动设备更精确地观察到结果。

7.    注脂时，请保持最少高出管线压力1000psi的压力。一般来说，对于卡麦隆阀门，过高的注脂压力似乎不太安全。任何时候当采用O型环作为密封时，你必须小心不要过压使之被冲出。咨询你的制造厂以确认你作业时的注意事项。

8.    如果你不能保持希望的压力，一种可能是注入的材料没有到达出问题的地方而是溢入到管线。请考虑以下的选择：

A.尝试注入密封脂建立一个临时的密封（10到20%的阀门所需量）堵住泄漏点，以获得机会保持住压力。重新尝试清洗步骤直到足量的阀门清洗液全部注入。

     B.对于卡麦隆球阀有旋转阀座时，操作阀门尝试将有问题的区域靠近注脂口。

注：一些老的卡麦隆球阀可能没有边缘或防垃圾密封。由于不能保持，这
