一、进口铜闸阀产品概述：

进口铜闸阀关闭时,密封面可以只依靠介质压力来密封，即只依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封，这就是自密封。大部分闸阀是采用强制密封的，即阀门关闭时，要依靠外力强行将闸板压向阀座，以保证密封面的密封性。闸阀是通过手轮转驱闸板沿通道轴线垂直方向移动切断接通介质流的控制部件，在使用过程中，阀门必须是全开或全关，不能用作调节流量。

1、 Introduction of imported bronze gate valve products:

When the imported bronze gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, only rely on the medium pressure to press the sealing surface of the gate to the seat on the other side to ensure the sealing surface, which is self sealing. Most gate valves are forced to seal, that is, when the valve is closed, the gate should be forced to the valve seat by external force, so as to ensure the tightness of the sealing surface. The gate valve is a control component which cuts off the medium flow through the vertical movement of the gate along the channel axis through the hand wheel. In the process of use, the valve must be fully open or closed, and can not be used to adjust the flow.
