蝶閥的另一個名字是翻板閥。蝶閥的作用是在低壓管道中關閉開關。蝶閥的閥門企業可以通過控制存在很多東西，比如空氣和誰，以及社會各種腐蝕性的東西。在相關管道中，主要起到調解和切割的作用。蝶閥的起閉件在外觀上看起來像一個通過圓盤蝶板，可以我們繞著自己體內的軸板旋轉，最終能夠達到企業關閉和調解的效果。

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.

蝶閥的蝶板由閥桿驅動。如果旋轉90度，則達到關閉程序。介質的流量可以通過調節蝶板的偏轉角度來控制。

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.

蝶閥和閘閥的工作范圍：

The working range of butterfly valves and gate valves:

蝶閥的應用范圍很多，如天然氣和天然氣工業、液化石油氣和冷熱空氣工業。在建筑業中，蝶閥可用于輸送各種腐蝕性介質，也可用于調節和相介質。

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.

閘閥在這里的作用研究相對比較單一，只能起到全開或全關的作用，在密封面角度進行工作人員容易導致產生偏差，所以我們這種閘閥也叫彈性閘閥。

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.

閘閥關閉時，只能通過介質產生的壓力在密封面上達到密封效果。大部分閘閥是強制密封的。閘閥關閉時，利用外力保證相關密封面的密封性能。

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.

蝶閥和閘閥在運動方式上有什么區別？

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

移動時，閘閥上方的閘板與閥桿一起工作，也稱為開桿閘閥。當通過閥體上方的導槽時，旋轉功能可以轉化為直線運動。打開閥門時，無法監控流體通道。全閥打開時，可根據閘板位置確定。手動傳動閥桿時，可提升相關閘板。這種閥門叫做暗桿閘閥。

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.
