| 1、用途Use |
适用于区域供热（热电联产）、输热、输油及除氧水等工业管钱。
Suitable for the pipeline to transfer cogeneration,cogeneration,heating,oil,deoxygenized water and etc. |
| 2、结构特性Structure Features |
阀门是由全焊接的阀体和增强四氟密封垫组成，阀门可在有杂质化学物质的情况下进行频繁操作，运行可靠。采用浮动球结构，斜面弹性垫圈保证密封圈紧压在球体之上，即使在压力不稳定的情况下，阀门也可以保证良好的密封性。阀杆可加长，易用于保温。
The valve is composed by a full welding body together with the RPTFE sealing which ensures the valve can work well in case of there are imoutries or chemical substance.Floating ball structure and the flexible seat will ensure the ball and the sealing connects each other tightly.Evon when the pressure is not stable,the valve can also have a good sealing. The stem can be extended which is good for keeping the tempeture stable. |
