球形阀门 [qiú xíng fá mén]
ball check
- 注意：这种阀门是采用两个球形制动器实现静电接地，确保阀杆阀体和球体之间的电镀连续性。
Note: Valves are static grounded by two ball detents that insure electro-continuity between the stem body and ball. - 重力球形止回阀可以变为通风阀，只需用漂浮球体更换标准球体，然后在安装时将阀门倒置，使其阀座向上即可。
Gravity ball check valves are converted to vent valves by replacing the standard ball with a floater ball and inverting the valve at installation–with seat up. - 未来的客户发现它能够制造成铸模绝缘材料、阀门零件、细长的物品、台球、球形柄、纽扣、刀柄以及各种各样的物件。
Would-be customers discovered it could be fashioned into molded insulation, valve parts, pipe stems, billiard balls, knobs, buttons, knife handles and all manners of items.
