With flow through valve, primary check opens away from diaphragm seal.
清洗：检查或更换磨损的阀门阀瓣，断开控制管线，采用钝工具和锤打阀盖凸耳从阀体上旋下阀盖。
To CLEAN: Inspect or replace worn valve disc, disconnect control pipe and unscrew bonnet from valve body using blunt tool and hammer on bonnet lugs.
当流体通过阀门时，第一阀瓣开启，从隔膜密封上离开。
With flow through valve, primary disc opens away from diaphragm seal.
密封的弹性使得阀门阀体和阀瓣能够接触或扩张，避免了由于温度波动而产生堵塞的危险。
The resiliency of the seal allows the valve body and disc to contract or expand, without the risk of jamming due to temperature fluctuations.
阀门阀瓣可以迅速更换。
旋转式止回阀也可以安装在垂直位置，此时阀瓣应该无法达到阀门的位置。
The swing check valve can also be mounted to the vertical position, provided the disc should not reach the valve position.
可更换不锈钢阀座和阀门阀瓣。
这个阀瓣总成在阀门全行程中保持与导向装置的接触。
The disc assembly maintains contact with the guides through the full valve stroke.
这种阀门的进口和阀体为一件式铸件，确保了阀瓣，阀座和芯轴的对齐和平稳运动。
The valve inlet and body are one integral casting assuring proper alignment of disc, seat and spindle for smooth action.
阀瓣支架可拆卸进行阀瓣更换，无需拆卸阀门，不需要特殊工具。
Disc holder removable for replacement of disc without dismantling the valve - no special tools required.
第二瓣塞子上安装的高端核心的阀门打开。
A second valved stopper was installed on the top end of the core with the valve open.
除了TFE阀瓣和填料，以及标签牌以外，标准配置阀门中的所有部件都是相同的。
Except for TFE disc and packing, and identification tag, all parts are identical to standard valves.
同时，可以利用调整阀瓣的自重、弹簧的弹力以及阀瓣的底孔大小来确定阀门的开启压力和启闭时间。
Meanwhile, the flap valve can be used to adjust weight, spring tension and the bottom outlet valve flap valve opening size to determine the pressure and open and close time.
通常这种阀门是自动工作的，在一个方向流动的流体压力作用下，阀瓣打开；
This valve is normally automatic work, in a direction of flow of fluid under pressure, open the flap valve;
适用于各类阀门的阀座，阀瓣环形平面的密封研磨。
Suitable for various valve flap, flap ring panel seal grinding.
气动刀闸阀气动阀门价格表气动管夹阀气动角座阀闸阀的作用是利用阀瓣沿通路中心的垂直线方向移动来实现开启或关闭管道通路。
