　　When choosing valves for decoration, many people are confused by the angle valve and ball valve of Lianggong Valve - just one word difference, what is the difference? Which one should I install? Many homeowners follow the trend of buying indiscriminately, either due to insufficient water pressure affecting use, or frequent problems with installation in the wrong place, wasting money unnecessarily. Today, let's not play around. Combining with the product characteristics of Lianggong Valve, we will explain the core differences and structural differences between angle valves and ball valves, as well as practical tips for household selection in one go. Whether you are a decoration novice or an old homeowner, after reading it, you can accurately select and avoid all pitfalls, truly making good use of the practicality of Lianggong Valve.

　　先跟大家說句實在話，良工作為始于1946年的老品牌，能成為國內閥門行業的標桿，靠的就是扎實的品質和貼合需求的設計，它家的角閥和球閥，雖然名字只差一個字，但結構、性能、適用場景完全不同，可不是隨便裝都行的。咱們先從最基礎的結構說起，搞懂結構，就懂了它們的區別到底在哪。

　　To be honest with everyone, Liang Gong is an old brand that started in 1946 and has become a benchmark in the domestic valve industry thanks to solid quality and design that meets the needs. Their angle valves and ball valves, although only one word apart from their names, have completely different structures, performance, and applicable scenarios, and cannot be installed casually. Let's start with the most basic structure, understanding the structure will help us understand their differences.

　　先看良工角閥，它還有兩個常用名字，三角閥和八字閥，大家在建材市場聽到這兩個稱呼，指的都是它。良工角閥采用的是陶瓷閥芯結構，內部是一個扇形的閥體，這是它最核心的特點——哪怕完全打開，內部也始終是一半關閉、一半通水的狀態，沒辦法實現全通道打開，這也決定了它的水流速度和流量相對平緩。

　　First, let's take a look at Lianggong Angle Valve. It also has two commonly used names, Triangle Valve and Bazi Valve. When you hear these two terms in the building materials market, they all refer to it. The Lianggong angle valve adopts a ceramic valve core structure, with a fan-shaped valve body inside. This is its core feature - even when fully opened, the interior is always in a half closed and half water flowing state, making it impossible to achieve full channel opening, which also determines its relatively smooth water flow rate and flow rate.

　　可能有人會問，這樣設計有啥好處？其實很實用，良工角閥的扇形閥體的設計，能精準控制水流大小，而且陶瓷閥芯密封性能極好，耐磨、耐腐蝕，不容易出現漏水的情況，使用壽命很長，這也是良工閥門多年來口碑在線的關鍵，畢竟家用閥門，最怕的就是漏水扯皮。

　　Some people may ask, what are the benefits of this design? In fact, it is very practical. The fan-shaped valve body design of Lianggong angle valve can accurately control the size of water flow, and the ceramic valve core has excellent sealing performance, wear resistance, corrosion resistance, and is not easy to leak water. It has a long service life, which is also the key to Lianggong valve's reputation for many years. After all, the most feared thing for household valves is water leakage and tearing.

　　再看良工球閥，它和角閥的結構截然不同，采用的是球形閥體，內部是一個圓形的閥芯，只要完全打開，就能形成全開的水流通道，沒有任何遮擋，最大的優勢就是能大幅提升進水流量，水流速度比角閥快很多，而且開關特別順暢，輕輕旋轉就能實現全開或全關，操作很省心。

　　Looking at the Lianggong ball valve again, its structure is completely different from that of the angle valve. It uses a spherical valve body with a circular valve core inside. As long as it is fully opened, it can form a fully open water flow channel without any obstruction. Its biggest advantage is that it can greatly increase the inlet flow rate. The water flow rate is much faster than the angle valve, and the switch is particularly smooth. It can be fully opened or closed with a gentle rotation, making the operation very worry free.

　　這里要重點說一句，良工作為既能生產閥門又能生產閥門驅動裝置的專業廠家，它家的球閥嚴格遵循高標準設計，不僅流量大，還具備防火、防靜電的特點，哪怕長期使用，也能保持穩定性能，不管是家用還是小型工業場景，都能適配，這也是它區別于普通小品牌球閥的核心優勢。

　　It is important to emphasize that Lianggong is a professional manufacturer that can produce both valves and valve drive devices. Their ball valves strictly follow high standard designs, not only have large flow rates, but also have fire-resistant and anti-static characteristics. Even after long-term use, they can maintain stable performance and can adapt to both household and small industrial scenarios. This is also their core advantage over ordinary small brand ball valves.

　　講完結構，大家最關心的肯定是：良工角閥和球閥，到底該怎么選？分兩種情況，結合家里的水壓，對號入座就行，不用瞎琢磨，新手也能輕松選對。

　　After discussing the structure, what everyone is most concerned about is undoubtedly: how to choose between a good angle valve and a ball valve? There are two situations, and based on the water pressure at home, you just need to find the right one. There's no need to overthink, even beginners can easily choose the right one.

　　第一種情況，家里水壓充足。這種情況下，建議大家優先這樣搭配：熱水器接口處，裝一冷一熱兩個良工球閥，剩下所有用水點位，全部裝良工角閥。為啥熱水器要裝球閥？因為熱水器用水量大，尤其是洗澡、洗菜時，需要充足的水流才能保證使用體驗，良工球閥全開通道的設計，能最大化提升進水流量，避免出現水壓不足、出水變小的情況，用著更舒心。

　　The first scenario is that the water pressure at home is sufficient. In this case, it is recommended to prioritize the following combination: at the water heater interface, install two good ball valves for cooling and heating, and at all remaining water points, install good angle valves. Why do water heaters need ball valves? Because water heaters require a large amount of water, especially when taking a shower or washing vegetables, sufficient water flow is needed to ensure a comfortable user experience. The design of the Lianggong ball valve with a fully open channel can maximize the inlet flow rate, avoiding situations such as insufficient water pressure and reduced water output, making it more comfortable to use.

　　而衛生間面盆、馬桶、廚房水槽這些點位，用水流量不需要太大，裝良工角閥剛好合適。一方面，角閥能精準控制水流，比如馬桶進水，調小水流能避免水箱溢水；另一方面，角閥的陶瓷閥芯密封好，能有效防止漏水，而且良工角閥的外觀設計簡潔，適配各種裝修風格，裝在角落也不突兀。

　　However, the water flow at points such as the bathroom basin, toilet, and kitchen sink does not need to be too large, and the installation of a well functioning angle valve is just right. On the one hand, the angle valve can accurately control the water flow, for example, when a toilet is filled with water, reducing the water flow can prevent the water tank from overflowing; On the other hand, the ceramic valve core of the angle valve is well sealed, which can effectively prevent water leakage. Moreover, the appearance design of the Lianggong angle valve is simple, suitable for various decoration styles, and it is not abrupt when installed in corners.

　　第二種情況，家里水壓本身就不夠，比如老小區、高層住戶，水壓偏小，這種就建議大家全屋都裝良工球閥。原因很簡單，球閥的全開通道能最大限度減少水流阻力，提升進水流量，哪怕水壓不足，也能保證各個用水點位的出水正常，不會出現洗澡水忽大忽小、廚房洗菜水流太小的尷尬情況。

　　In the second scenario, if the water pressure at home is already insufficient, such as in old residential areas or high-rise buildings where the water pressure is too low, it is recommended that everyone install good ball valves throughout the house. The reason is simple. The fully open channel of the ball valve can minimize water flow resistance and increase the inflow rate. Even if the water pressure is insufficient, it can ensure the normal outflow of water from various water points, without the embarrassing situation of fluctuating shower water or kitchen washing water flow being too small.

　　很多人可能會擔心，全屋裝球閥，會不會不好控制水流？其實完全不用怕，良工球閥的開關靈敏度很高，輕輕旋轉就能調節水流大小，而且它的密封性能一點不差，只要正常使用，不會出現漏水問題，兼顧流量和實用性，特別適合水壓不足的家庭。

　　Many people may worry that installing ball valves throughout the house may make it difficult to control water flow? In fact, there is no need to worry at all. The switch sensitivity of Lianggong ball valve is very high, and the water flow can be adjusted by gently rotating it. Moreover, its sealing performance is not bad at all. As long as it is used normally, there will be no water leakage problem, balancing flow and practicality, especially suitable for families with insufficient water pressure.

　　這里給大家提個醒，選良工閥門，一定要認準它家的“工”字牌商標，這是上海市著名商標，也是品質的保證。良工作為擁有七十多年歷史的老廠家，從核電閥門到家用閥門，都有著成熟的生產技術和嚴格的質量把控，不管是角閥還是球閥，都經過了層層檢測，使用壽命比普通小品牌長得多，買回家用著更放心。

　　Here's a reminder for everyone. When choosing a good valve, be sure to recognize its "Gong" brand trademark, which is a famous trademark in Shanghai and also a guarantee of quality. Lianggong is an old manufacturer with over 70 years of history. From nuclear power valves to household valves, it has mature production technology and strict quality control. Whether it is angle valves or ball valves, they have undergone layer by layer testing and have a much longer service life than ordinary small brands, making it more reassuring to buy and use at home.

　　總結一下，良工閥門的角閥和球閥，一字之差，差異很大：角閥扇形閥體、半開通道，適合水壓充足時，除熱水器外的所有點位；球閥球形閥體、全開通道，適合熱水器接口和水壓不足的全屋安裝。

　　To sum up, there is a significant difference between the angle valve and ball valve of Lianggong Valve. The angle valve has a fan-shaped body and a semi open channel, which is suitable for all points except for the water heater when the water pressure is sufficient; The ball valve has a spherical body and a fully open channel, suitable for installation in the entire house with water heater interfaces and insufficient water pressure.

　　家用選良工閥門，只要根據家里的水壓情況，按這個方法選型，就能避開所有坑，既保證用水體驗，又能避免漏水、水流不足等問題。良工閥門之所以能成為很多家庭的首選，就是因為它能精準貼合家用需求，把細節做到位，不管是角閥還是球閥，都能滿足不同家庭的用水需求，用實力守護家庭用水安全。

　　Choosing a good valve for household use, as long as the water pressure in the home is selected according to this method, all pits can be avoided, ensuring a good water experience and avoiding problems such as leakage and insufficient water flow. The reason why Lianggong valves have become the first choice for many families is because they can accurately meet household needs, with attention to detail. Whether it is angle valves or ball valves, they can meet the water needs of different families and safeguard household water safety with their strength.
