蝶阀的另一个名字是翻板阀。蝶阀的作用是在低压管道中关闭开关。蝶阀的阀门企业可以通过控制存在很多东西，比如空气和谁，以及社会各种腐蚀性的东西。在相关管道中，主要起到调解和切割的作用。蝶阀的起闭件在外观上看起来像一个通过圆盘蝶板，可以我们绕着自己体内的轴板旋转，最终能够达到企业关闭和调解的效果。

Another name for butterfly valve is flap valve. The function of butterfly valve is to close the switch in low-pressure pipelines. Butterfly valve enterprises can control many things, such as air and others, as well as various corrosive substances in society. In the relevant pipelines, it mainly plays a role in mediation and cutting. The opening and closing components of butterfly valves look like a disc butterfly plate in appearance, which can rotate around the axis plate inside our body, ultimately achieving the effect of enterprise closure and mediation.

蝶阀的蝶板由阀杆驱动。如果旋转90度，则达到关闭程序。介质的流量可以通过调节蝶板的偏转角度来控制。

The butterfly plate of the butterfly valve is driven by the valve stem. If rotated 90 degrees, the program will be closed. The flow rate of the medium can be controlled by adjusting the deflection angle of the butterfly plate.

蝶阀和闸阀的工作范围：

The working range of butterfly valves and gate valves:

蝶阀的应用范围很多，如天然气和天然气工业、液化石油气和冷热空气工业。在建筑业中，蝶阀可用于输送各种腐蚀性介质，也可用于调节和相介质。

Butterfly valves have many applications, such as natural gas and natural gas industry, liquefied petroleum gas and hot and cold air industry. In the construction industry, butterfly valves can be used to transport various corrosive media, as well as to regulate and phase media.

闸阀在这里的作用研究相对比较单一，只能起到全开或全关的作用，在密封面角度进行工作人员容易导致产生偏差，所以我们这种闸阀也叫弹性闸阀。

The research on the role of gate valves here is relatively limited, and they can only play a fully open or fully closed role. Working at the sealing surface angle can easily cause deviations, so our type of gate valve is also called an elastic gate valve.

闸阀关闭时，只能通过介质产生的压力在密封面上达到密封效果。大部分闸阀是强制密封的。闸阀关闭时，利用外力保证相关密封面的密封性能。

When the gate valve is closed, the sealing effect can only be achieved on the sealing surface through the pressure generated by the medium. Most gate valves are forced to seal. When the gate valve is closed, external force is used to ensure the sealing performance of the relevant sealing surface.

蝶阀和闸阀在运动方式上有什么区别？

What is the difference in motion between butterfly valves and gate valves?

移动时，闸阀上方的闸板与阀杆一起工作，也称为开杆闸阀。当通过阀体上方的导槽时，旋转功能可以转化为直线运动。打开阀门时，无法监控流体通道。全阀打开时，可根据闸板位置确定。手动传动阀杆时，可提升相关闸板。这种阀门叫做暗杆闸阀。

When moving, the gate above the gate valve works together with the valve stem, also known as an open stem gate valve. When passing through the guide groove above the valve body, the rotational function can be converted into linear motion. When the valve is opened, the fluid channel cannot be monitored. When the full valve is open, it can be determined based on the position of the gate. When manually driving the valve stem, the relevant gate can be raised. This type of valve is called a concealed stem gate valve.
