球閥，作為一種常見的閥門類型，在流體控制系統中扮演著舉足輕重的角色。特別是在商業大樓和公共建筑的暖通制冷系統中，球閥的通斷和流量調節控制功能發揮著不可替代的作用。那么，球閥究竟屬于什么閥門呢？

　　Ball valves, as a common type of valve, play a crucial role in fluid control systems. Especially in the HVAC systems of commercial and public buildings, the on/off and flow control functions of ball valves play an irreplaceable role. So, what kind of valve does a ball valve belong to?

　　球閥屬于旋轉式閥門的一種。

　　Ball valves are a type of rotary valve.

　　【一】它的工作原理是通過球體在閥體內的旋轉來控制流體的通斷和流量大小。

　　【1】 Its working principle is to control the on/off and flow rate of fluid through the rotation of a sphere inside the valve body.

　　①　當球體旋轉至與閥體通道重合時，閥門處于開啟狀態，流體可以順利通過；

　　① When the sphere rotates to coincide with the valve body channel, the valve is in the open state and the fluid can pass smoothly;

　　②　而當球體旋轉至與閥體通道垂直時，閥門關閉，流體被截斷。

　　② When the sphere rotates perpendicular to the valve body channel, the valve closes and the fluid is cut off.

　　這種旋轉式的操作方式使得球閥具有開關迅速、操作便捷的特點。

　　This rotary operation method makes the ball valve have the characteristics of quick opening and easy operation.

　　【二】在閥門的分類中，球閥還可以根據其結構和用途進一步細分。比如，

　　【2】 In the classification of valves, ball valves can be further subdivided based on their structure and purpose. for example,

　　①　根據球體與閥座之間的密封形式，球閥可以分為浮動球閥和固定球閥；

　　① According to the sealing form between the ball and the valve seat, ball valves can be divided into floating ball valves and fixed ball valves;

　　②　根據驅動方式的不同，又可以分為手動球閥、氣動球閥、電動球閥等。

　　② According to the different driving methods, it can be divided into manual ball valves, pneumatic ball valves, electric ball valves, etc.

　　而這款艾德默·ZEASY甄易系列電動球閥，正是球閥的一種變體，它通過電動執行器驅動球體旋轉，實現了對流體通斷和流量的遠程準確控制。

　　And this Edmo ZEASY Zhenyi series electric ball valve is a variant of the ball valve, which drives the ball to rotate through an electric actuator, achieving remote and accurate control of fluid on/off and flow rate.

　　【三】這款電動球閥的設計特點

　　【3】 The design features of this electric ball valve

　　①　在于其內置一體式配流碟，這種設計不僅使得閥門在面臨反向壓差時仍能穩定工作，而且還賦予了閥門執行器手動功能，增強了其操作的靈敏性和可靠性。在商業大樓和公共建筑的暖通制冷系統中，熱水和冷凍水的通斷和流量調節是至關重要的。這款電動球閥通過準確的流量控制，確保了系統的高能運行和溫度的穩定性。

　　① Due to its built-in integrated distribution disc, this design not only ensures stable operation of the valve when facing reverse pressure differentials, but also endows the valve actuator with manual function, enhancing its sensitivity and reliability in operation. The on-off and flow regulation of hot and chilled water is crucial in the HVAC systems of commercial and public buildings. This electric ball valve ensures high-energy operation and temperature stability of the system through accurate flow control.

　　②　此外，該電動球閥采用石墨增強PTEE材料作為閥座，這種材料在銹水環境中具有突出的無泄漏壽命和密封性能，大大提高了閥門的使用壽命和安全性。

　　② In addition, the electric ball valve adopts graphite reinforced PTEE material as the valve seat, which has outstanding leak free life and sealing performance in rusty water environment, greatly improving the service life and safety of the valve.

　　③　配流碟內置一體式的設計，使得閥門在統一孔徑下能夠提供不同的流量系數（KV）值，從而實現了等百分比流量特性，這對于準確的溫度控制來說至關重要。

　　③ The integrated design of the distribution plate allows the valve to provide different flow coefficient (KV) values under a uniform aperture, thereby achieving equal percentage flow characteristics, which is crucial for accurate temperature control.

　　綜上所述

　　In summary

　　①　球閥作為一種旋轉式閥門，在流體控制系統中具有廣泛的應用。

　　① Ball valves, as a type of rotary valve, have a wide range of applications in fluid control systems.

　　②　而這款電動球閥，以其獨特的設計和卓異的性能，在商業大樓和公共建筑的暖通制冷系統中發揮著不可或缺的作用。無論是其快速的開關速度、便捷的操作方式，還是其準確的流量控制、可靠的安全性能，都使得它成為現代流體控制系統中不可或缺的一部分。

　　② This electric ball valve, with its unique design and outstanding performance, plays an indispensable role in the HVAC and refrigeration systems of commercial and public buildings. Whether it is its fast switching speed, convenient operation mode, accurate flow control, or reliable safety performance, it has become an indispensable part of modern fluid control systems.
