球阀跟角阀它们的区别在于哪里？哪个地方应该用球阀，哪个地方应该用角阀给大家去讲一下。这是球阀里边它有个球，看到没？我打开以后它可以全部打开，我关上以后它可以全部关闭，这个是球阀，我们再看一下角阀，角阀是这种的，来大家看一眼，全部关闭以后它就关上了。我打开以后看到吗？我打开以后它只能打开一半。它过水量只能达到50%。

　　What is the difference between ball valves and angle valves? Where should ball valves be used and where should angle valves be used? Let me explain to you. This is a ball valve. It has a ball inside, do you see it? After I open it, it can be fully opened, and after I close it, it can be fully closed. This is a ball valve. Let's take a look at the angle valve again. The angle valve is like this. Let's take a look. Once it is fully closed, it will be closed. Do you see it when I open it? After I opened it, it could only be opened halfway. It can only reach a water flow rate of 50%.

　　好多人都觉得，唉，这种过水量少，我应该全部都用这个球阀，因为球阀数量大，是不是你感觉水压大，其实这样想是不对的哈，因为它的优点在于它的水量大，它的缺点也在于它的水量大。

　　Many people think, oh, this type of ball valve has less water flow. I should use this ball valve for all of them because the number of ball valves is large. Do you feel that the water pressure is high? Actually, this is not the right way to think, because its advantage is that it has a large water volume, and its disadvantage is also that it has a large water volume.

　　如果说我们用这个球阀给它安装在我们的马桶上，给它安装在我们的洗脸盆上，你会出现一个什么情况呢？就是我们的马桶。你用个一年左右的时间，你的水件会坏的特别快，因为它压力太大了，让你的水件漏水，然后还有就是我们的这个洗脸盆，洗脸盆，龙头，洗菜盆，龙头水压过大的情况之下也会造成它漏水，因为它长时间它的阀芯在高压之下，它特别容易出现损坏这种情况，那么我们就得搭配去使用。

　　What would happen if we install this ball valve on our toilet and washbasin? It's our toilet. If you use it for about a year, your water fittings will break very quickly because the pressure is too high, causing your water fittings to leak. In addition, our washbasin, washbasin, faucet, vegetable washing basin, and faucet can also leak when the water pressure is too high. Because its valve core is under high pressure for a long time, it is particularly prone to damage. Therefore, we need to use them together.

　　一般我们的什么马桶是用角阀洗脸盆儿，用角阀洗菜盆儿也用角阀，然后球阀的话呢，是用在我们的燃气热水器和电水器的。为什么说热水器用它呢？因为我们的电水器一般我们供的那个花洒都是大顶盆，大手盆，它需要的水量大，而且我们的燃气热水器的话呢，有时候你同时供两个卫生间，三个卫生间，所以说你的水量不能受影响，我们是用球阀的，它是分开的，它不是说全部都用角阀，也不是说全部都用球阀的，它俩是搭配去使用的。

　　Generally, our toilets use angle valves for washbasins, vegetable basins, and ball valves. They are used in our gas water heaters and electric water heaters. Why is it said that water heaters use it? Because our electric water heaters usually have large showerheads and large basins, which require a large amount of water. And for our gas water heaters, sometimes you supply two or three bathrooms at the same time, so your water volume cannot be affected. We use ball valves, which are separate. It doesn't mean that all of them use angle valves, nor does it mean that all of them use ball valves. They are used in combination.

　　还有就是不管是球阀也好，还是角阀也好，尽量去选这种红蓝分开的，因为你冷水有问题，你去检修冷水热水有问题你去检修热水很方便。

　　Also, whether it's a ball valve or an angle valve, try to choose this type of red blue separation, because if you have a problem with the cold water, it's very convenient for you to repair the hot water if you have a problem with the cold water.
