Is the faucet thread left-hand or right-hand?

You can use the following methods to judge:

1. Direction of rotation: Threads are divided into left-hand and right-hand threads. The thread that is screwed in when turning clockwise is called a right-hand thread, and conversely, the thread that is screwed in when turned counterclockwise is called a left-hand thread.

2. If the thread or screw is perpendicular to the horizontal plane, you can see that each thread is inclined. If the right side is higher, the thread is right-handed. If the left side is high, the thread is left-handed.

Both stop valves and gate valves adopt the design principle of opening counterclockwise and closing clockwise. Old-fashioned faucets are stop valves. Nowadays, water valves commonly used in home decoration, such as hot and cold water mixing valves, angle valves, and quick-open faucets, are all ball valves. The opening and closing of the ball valve are related to the rotation angle. Ceramic valve core ball valve.
