| 1. | Wedge ? fully guided wedge precision fitted to body seats for maximum shutoff
楔形闸板-全导向楔形结构，精密配合阀体阀座，实现最有效的关闭。 |
| 2. | Consult factory for centerline to top dimensions ( open and closed ) for split wedge valves
对于拼合楔形闸板阀门的中心线至顶端(开启和关闭状态下)的尺寸，请咨询工厂。 |
| 3. | Flexible or split wedges are recommended for service above 500 ? to avoid wedge binding due to thermal expansion
对于温度超过260的应用环境，建议采用柔性或拼合式楔形闸板，避免楔形闸板由于热膨胀而被卡住。 |
| 4. | For the following valves with his option the center to top dimensions ( open and closed ) must be increased approximately 2 inches , consult factory for exact dimensions
对于拼合楔形闸板阀门的中心线至顶端(开启和关闭状态下)的尺寸，请咨询工厂。 |
| 5. | Another important aspect in the manufacture of these valves is the clearances at the critical metal interfaces ( wedge / body guides , stem / back seat bushing , etc . )
这种阀门的制造中的另一个重要方面是关键金属表面(楔形闸板/阀体导向，阀杆/后阀座衬套，等等)的之间的间隙。 |
| 6. | Gate valves are offered in two designs : parallel disc and flexible wedge . parallel disc are position seated ; flexible wedge are torque seated when closing
我们提供的闸阀的结构形式具有两种：平行阀瓣和弹性楔形闸板。平行阀瓣为定位阀座密封；弹性楔形闸板在关闭时则是扭矩阀座密封。 |
| 7. | Parallel seat gate and seat ring construction can be furnished for high differential pressure services or where high piping loads or thermal expansion may cause sticking of a wedge type gate
平行阀座闸阀和阀座环结构可以应用在高压差应用环境中，或者高管道负载，或可能导致楔形闸板闸阀卡住的热膨胀应用环境中。 |
