阀弹簧

When the external control pressure increases to the shutoff pressure setting point of the valve, the external control pressure acting on the underside of the diaphragm, which breaks the balance of the compression of the pressure spring and the latch lever, triggers the latch and disengages valve disc arm from the latch.

当外接控制感应压力﹝即减压下游压力﹞升到此阀关断压设定点时，控制压作用于皮膜下层破坏压力弹簧压缩与闩杆间的平衡，然后扳开闩扣并从闩扣释放阀门封盘。

Position upper and lower stem butterfly Butt-clamped rubber-lined butterfly valve spring seal body, providing a sealing surface pressure of making the two-paste together tightly.

上下两位置的阀杆蝶形弹簧密封机构，提供了一个压力使得两密封面紧紧地贴在一起。

These two components take the corresponding measures are:① in the needle pre-set multi-stage filter, filter mesh filter Kong progressively reduced, in order to retain solid particles of impurities;② rubber diaphragm with high-quality products, and regularly check the diaphragm and the hydraulic control valve spring situation.

对这两个部件采取的相应措施是：①在针阀前设置多级过滤器，过滤器滤网孔目逐级缩小，以截留固体颗粒杂质；②橡胶隔膜采用优质产品，并定期检查隔膜和水力控制阀内弹簧的情况。

When the device has just started, low-temperature condensed water pipe occurs, double metal film is flat, the spool of elastic in the spring, the valve in the open position.

当装置刚启动时，管道出现低温冷凝水，双金属片是平展的，阀芯在弹簧的弹力下，阀门处于开启位置。

When the device just starting when the low-temperature condensed water pipe occurs, double metal film is flat, and the elastic spring heart valve, the valve in the open position.

当装置刚起动时，管道出现低温冷凝水，双金属片是平展的，阀心在弹簧的弹力下，阀门处于开启位置。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
