球閥，作為一種常見的閥門類型，在流體控制系統(tǒng)中扮演著舉足輕重的角色。特別是在商業(yè)大樓和公共建筑的暖通制冷系統(tǒng)中，球閥的通斷和流量調(diào)節(jié)控制功能發(fā)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(zhuǎn)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(nèi)的旋轉(zhuǎn)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(dāng)球體旋轉(zhuǎn)至與閥體通道重合時，閥門處于開啟狀態(tài)，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(dāng)球體旋轉(zhuǎn)至與閥體通道垂直時，閥門關(guān)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(zhuǎn)式的操作方式使得球閥具有開關(guān)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(jù)其結(jié)構(gòu)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(jù)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(jù)驅(qū)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(zhí)行器驅(qū)動球體旋轉(zhuǎn)，實現(xiàn)了對流體通斷和流量的遠程準(zhǔn)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(shè)計特點

　　【3】 The design features of this electric ball valve

　　①　在于其內(nèi)置一體式配流碟，這種設(shè)計不僅使得閥門在面臨反向壓差時仍能穩(wěn)定工作，而且還賦予了閥門執(zhí)行器手動功能，增強了其操作的靈敏性和可靠性。在商業(yè)大樓和公共建筑的暖通制冷系統(tǒng)中，熱水和冷凍水的通斷和流量調(diào)節(jié)是至關(guān)重要的。這款電動球閥通過準(zhǔn)確的流量控制，確保了系統(tǒng)的高能運行和溫度的穩(wěn)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(huán)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(nèi)置一體式的設(shè)計，使得閥門在統(tǒng)一孔徑下能夠提供不同的流量系數(shù)（KV）值，從而實現(xiàn)了等百分比流量特性，這對于準(zhǔn)確的溫度控制來說至關(guān)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(zhuǎn)式閥門，在流體控制系統(tǒng)中具有廣泛的應(yīng)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(shè)計和卓異的性能，在商業(yè)大樓和公共建筑的暖通制冷系統(tǒng)中發(fā)揮著不可或缺的作用。無論是其快速的開關(guān)速度、便捷的操作方式，還是其準(zhǔn)確的流量控制、可靠的安全性能，都使得它成為現(xiàn)代流體控制系統(tǒng)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.
