　　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.

　　先跟大家说句实在话，良工作为始于1946年的老品牌，能成为国内阀门行业的标杆，靠的就是扎实的品质和贴合需求的设计，它家的角阀和球阀，虽然名字只差一个字，但结构、性能、适用场景完全不同，可不是随便装都行的。咱们先从最基础的结构说起，搞懂结构，就懂了它们的区别到底在哪。

　　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.

　　先看良工角阀，它还有两个常用名字，三角阀和八字阀，大家在建材市场听到这两个称呼，指的都是它。良工角阀采用的是陶瓷阀芯结构，内部是一个扇形的阀体，这是它最核心的特点——哪怕完全打开，内部也始终是一半关闭、一半通水的状态，没办法实现全通道打开，这也决定了它的水流速度和流量相对平缓。

　　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.

　　可能有人会问，这样设计有啥好处？其实很实用，良工角阀的扇形阀体的设计，能精准控制水流大小，而且陶瓷阀芯密封性能极好，耐磨、耐腐蚀，不容易出现漏水的情况，使用寿命很长，这也是良工阀门多年来口碑在线的关键，毕竟家用阀门，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.

　　再看良工球阀，它和角阀的结构截然不同，采用的是球形阀体，内部是一个圆形的阀芯，只要完全打开，就能形成全开的水流通道，没有任何遮挡，最大的优势就是能大幅提升进水流量，水流速度比角阀快很多，而且开关特别顺畅，轻轻旋转就能实现全开或全关，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.

　　这里要重点说一句，良工作为既能生产阀门又能生产阀门驱动装置的专业厂家，它家的球阀严格遵循高标准设计，不仅流量大，还具备防火、防静电的特点，哪怕长期使用，也能保持稳定性能，不管是家用还是小型工业场景，都能适配，这也是它区别于普通小品牌球阀的核心优势。

　　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.

　　讲完结构，大家最关心的肯定是：良工角阀和球阀，到底该怎么选？分两种情况，结合家里的水压，对号入座就行，不用瞎琢磨，新手也能轻松选对。

　　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.

　　第一种情况，家里水压充足。这种情况下，建议大家优先这样搭配：热水器接口处，装一冷一热两个良工球阀，剩下所有用水点位，全部装良工角阀。为啥热水器要装球阀？因为热水器用水量大，尤其是洗澡、洗菜时，需要充足的水流才能保证使用体验，良工球阀全开通道的设计，能最大化提升进水流量，避免出现水压不足、出水变小的情况，用着更舒心。

　　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.

　　而卫生间面盆、马桶、厨房水槽这些点位，用水流量不需要太大，装良工角阀刚好合适。一方面，角阀能精准控制水流，比如马桶进水，调小水流能避免水箱溢水；另一方面，角阀的陶瓷阀芯密封好，能有效防止漏水，而且良工角阀的外观设计简洁，适配各种装修风格，装在角落也不突兀。

　　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.

　　第二种情况，家里水压本身就不够，比如老小区、高层住户，水压偏小，这种就建议大家全屋都装良工球阀。原因很简单，球阀的全开通道能最大限度减少水流阻力，提升进水流量，哪怕水压不足，也能保证各个用水点位的出水正常，不会出现洗澡水忽大忽小、厨房洗菜水流太小的尴尬情况。

　　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.

　　很多人可能会担心，全屋装球阀，会不会不好控制水流？其实完全不用怕，良工球阀的开关灵敏度很高，轻轻旋转就能调节水流大小，而且它的密封性能一点不差，只要正常使用，不会出现漏水问题，兼顾流量和实用性，特别适合水压不足的家庭。

　　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.

　　这里给大家提个醒，选良工阀门，一定要认准它家的“工”字牌商标，这是上海市著名商标，也是品质的保证。良工作为拥有七十多年历史的老厂家，从核电阀门到家用阀门，都有着成熟的生产技术和严格的质量把控，不管是角阀还是球阀，都经过了层层检测，使用寿命比普通小品牌长得多，买回家用着更放心。

　　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.

　　总结一下，良工阀门的角阀和球阀，一字之差，差异很大：角阀扇形阀体、半开通道，适合水压充足时，除热水器外的所有点位；球阀球形阀体、全开通道，适合热水器接口和水压不足的全屋安装。

　　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.

　　家用选良工阀门，只要根据家里的水压情况，按这个方法选型，就能避开所有坑，既保证用水体验，又能避免漏水、水流不足等问题。良工阀门之所以能成为很多家庭的首选，就是因为它能精准贴合家用需求，把细节做到位，不管是角阀还是球阀，都能满足不同家庭的用水需求，用实力守护家庭用水安全。

　　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.
